This tool is a component of a cross-platform auto-update system.
It is responsible for performing the installation of an update after
the necessary files have been downloaded to a temporary directory.
It was originally written for use with Mendeley Desktop (see www.mendeley.com)
The tool consists of a single small binary which performs update installation,
an XML file format describing the contents of an update (an 'update script')
and a tool to create update scripts from a directory containing an installed application.
To perform an update, the application (or another separate tool) needs to download
the updater binary, an update script and one or more compressed packages
containing the files for the update to a temporary directory. It then needs
to invoke the updater, specifying the location where the application is installed,
the location of the compressed packages and the path to the update script.
Once the updater has been started, it:
1. Waits for the application to exit
2. Acquires the necessary priviledges to install the updates, prompting
the user if necessary.
3. Installs the updates, displaying progress to the user in a small dialog
4. Performs cleanup and any additional actions required as part of the update
5. Starts the new version of the main application.
In the event of a failure during the update, the installation is rolled back
to its previous state and a message is presented to the user.
## Building the Updater
Create a new directory for the build and from that directory run:
cmake <path to source directory>
make
The updater binary will be built in the src/ directory.
You should also run the tests in src/tests to verify that the updater is
functioning correctly.
## Preparing an Update
1. Create a directory containing your application's files,
laid out in the same way and with the same permissions as they would be when installed.
2. Create a config file specifying how the application's files should be
partitioned into packages - see tools/config-template.json
3. Use the tools/create-packages.rb script to create a file_list.xml file
and a set of package files required for updates.
4. Upload the file_list.xml file and packages to a server
After step 4 is done, you need to notify existing installs that an update
is available. The installed application then needs to download the
relevant packages, file_list.xml file and updater binary to a temporary
directory and invoke the updater.
See doc/update-hosting for more details on hosting and delivering the updates.
## Invoking the Updater
Once the application has downloaded an update, it needs to invoke it. The syntax is:
updater --install-dir <install-dir> --package-dir <package-dir> --script <script file>
Where `<install-dir>` is the directory which the application is installed into,
`<package-dir>` is the directory containing the packages required for the update
and `<script>` is the `file_list.xml` file describing the update.
Once the updater has run, it will launch the file specified in the `file_list.xml` file
as being the main application binary.
See the updater test in `src/tests/test-update.rb` for an example
of how to invoke the updater.
You should design the process used to download and launch the updater so that new
versions of the updater itself can be delivered as part of the update if necessary.
## Customizing the Updater
To customize the application name, organization and messages displayed by the updater:
1. Edit the AppInfo class (in AppInfo.h, AppInfo.cpp) to set the name
of the application and associated organization.
2. Replace the icons in src/resources
3. Change the product name and organization in src/resources/updater.rc
4. If you are building the updater on Windows and have a suitable Authenticode
certificate, use it to sign the Windows binary. This will make the application
show a less scary UAC prompt if administrator permissions are required
to complete the installation.
## Updater Dependencies
The external dependencies of the updater binary are:
* The C/C++ runtime libraries (Linux, Mac),
* pthreads (Linux, Mac),
* zlib (Linux, Mac)
* native UI library (Win32 API on Windows, Cocoa on Mac, GTK on Linux if available)
## Full and Delta Updates
The simplest auto-update implementation is for existing installs
to download a complete copy of the new version and install it. This is
appropriate if a full download and install will not take a long time for most users
(eg. if the application is small or they have a fast internet connection).
With this tool, a full-update involves putting all files in a build of
the application into a single package.
To reduce the download size, delta updates can be created which only include
the necessary files or components to update from the old to the new version.
The file_list.xml file format can be used to represent either a complete
install - in which every file that makes up the application is included,
or a delta update - in which case only new or updated files and packages
are included.
There are several ways in which this can be done:
* Pre-computed Delta Updates
For each release, create a full update plus delta updates from the
previous N releases. Users of recent releases will receive a small
delta update. Users of older releases will receive the full update.
* Server-computed Delta Updates
The server receives a request for an update from client version X and in response,
computes an update from version X to the current version Y, possibly
caching that information for future use. The client then receives the
delta file_list.xml file and downloads only the listed packages.
Applications such as Chrome and Firefox use a mixture of the above methods.
* Client-computed Delta Updates
The client downloads the file_list.xml file for the latest version and
computes a delta update file locally. It then downloads only the required
packages and invokes the updater, which installs only the changed or updated
files from those packages.
This is similar to Linux package management systems.

http://www.hackorama.com/anyoption/
AnyOption is a C++ class for easy parsing of complex commandline options. It also parses options from a rsourcefile in option value pair format.
AnyOption implements the traditional POSIX style character options ( -n ) as well as the newer GNU style long options ( --name ). Or you can use a simpler long option version ( -name ) by asking to ignore the POSIX style options.
AnyOption supports the traditional UNIX resourcefile syntax of, any line starting with "#" is a comment and the value pairs use ":" as a delimiter.
An option which expects a value is considered as an option value pair, while options without a value are considered flags.
Please read the header file for the documented public interface, and demo.cpp for an example of how easy it is to use AnyOption.
August 2004, added bug-fixes, and updates send by Michael Peters of Sandia Lab.
September 2006, fix from Boyan Asenov for a bug in mixing up option type indexes.
July 2011, fix from Min KJ and Costantino G for string allocation.

<h1> TinyXML </h1>
TinyXML is a simple, small, C++ XML parser that can be easily
integrated into other programs.
<h2> What it does. </h2>
In brief, TinyXML parses an XML document, and builds from that a
Document Object Model (DOM) that can be read, modified, and saved.
XML stands for "eXtensible Markup Language." It allows you to create
your own document markups. Where HTML does a very good job of marking
documents for browsers, XML allows you to define any kind of document
markup, for example a document that describes a "to do" list for an
organizer application. XML is a very structured and convenient format.
All those random file formats created to store application data can
all be replaced with XML. One parser for everything.
The best place for the complete, correct, and quite frankly hard to
read spec is at <a href="http://www.w3.org/TR/2004/REC-xml-20040204/">
http://www.w3.org/TR/2004/REC-xml-20040204/</a>. An intro to XML
(that I really like) can be found at
<a href="http://skew.org/xml/tutorial/">http://skew.org/xml/tutorial</a>.
There are different ways to access and interact with XML data.
TinyXML uses a Document Object Model (DOM), meaning the XML data is parsed
into a C++ objects that can be browsed and manipulated, and then
written to disk or another output stream. You can also construct an XML document
from scratch with C++ objects and write this to disk or another output
stream.
TinyXML is designed to be easy and fast to learn. It is two headers
and four cpp files. Simply add these to your project and off you go.
There is an example file - xmltest.cpp - to get you started.
TinyXML is released under the ZLib license,
so you can use it in open source or commercial code. The details
of the license are at the top of every source file.
TinyXML attempts to be a flexible parser, but with truly correct and
compliant XML output. TinyXML should compile on any reasonably C++
compliant system. It does not rely on exceptions or RTTI. It can be
compiled with or without STL support. TinyXML fully supports
the UTF-8 encoding, and the first 64k character entities.
<h2> What it doesn't do. </h2>
TinyXML doesn't parse or use DTDs (Document Type Definitions) or XSLs
(eXtensible Stylesheet Language.) There are other parsers out there
(check out www.sourceforge.org, search for XML) that are much more fully
featured. But they are also much bigger, take longer to set up in
your project, have a higher learning curve, and often have a more
restrictive license. If you are working with browsers or have more
complete XML needs, TinyXML is not the parser for you.
The following DTD syntax will not parse at this time in TinyXML:
@verbatim
<!DOCTYPE Archiv [
<!ELEMENT Comment (#PCDATA)>
]>
@endverbatim
because TinyXML sees this as a !DOCTYPE node with an illegally
embedded !ELEMENT node. This may be addressed in the future.
<h2> Tutorials. </h2>
For the impatient, here is a tutorial to get you going. A great way to get started,
but it is worth your time to read this (very short) manual completely.
- @subpage tutorial0
<h2> Code Status. </h2>
TinyXML is mature, tested code. It is very stable. If you find
bugs, please file a bug report on the sourceforge web site
(www.sourceforge.net/projects/tinyxml). We'll get them straightened
out as soon as possible.
There are some areas of improvement; please check sourceforge if you are
interested in working on TinyXML.
<h2> Related Projects </h2>
TinyXML projects you may find useful! (Descriptions provided by the projects.)
<ul>
<li> <b>TinyXPath</b> (http://tinyxpath.sourceforge.net). TinyXPath is a small footprint
XPath syntax decoder, written in C++.</li>
<li> <b>TinyXML++</b> (http://code.google.com/p/ticpp/). TinyXML++ is a completely new
interface to TinyXML that uses MANY of the C++ strengths. Templates,
exceptions, and much better error handling.</li>
</ul>
<h2> Features </h2>
<h3> Using STL </h3>
TinyXML can be compiled to use or not use STL. When using STL, TinyXML
uses the std::string class, and fully supports std::istream, std::ostream,
operator<<, and operator>>. Many API methods have both 'const char*' and
'const std::string&' forms.
When STL support is compiled out, no STL files are included whatsoever. All
the string classes are implemented by TinyXML itself. API methods
all use the 'const char*' form for input.
Use the compile time #define:
TIXML_USE_STL
to compile one version or the other. This can be passed by the compiler,
or set as the first line of "tinyxml.h".
Note: If compiling the test code in Linux, setting the environment
variable TINYXML_USE_STL=YES/NO will control STL compilation. In the
Windows project file, STL and non STL targets are provided. In your project,
It's probably easiest to add the line "#define TIXML_USE_STL" as the first
line of tinyxml.h.
<h3> UTF-8 </h3>
TinyXML supports UTF-8 allowing to manipulate XML files in any language. TinyXML
also supports "legacy mode" - the encoding used before UTF-8 support and
probably best described as "extended ascii".
Normally, TinyXML will try to detect the correct encoding and use it. However,
by setting the value of TIXML_DEFAULT_ENCODING in the header file, TinyXML
can be forced to always use one encoding.
TinyXML will assume Legacy Mode until one of the following occurs:
<ol>
<li> If the non-standard but common "UTF-8 lead bytes" (0xef 0xbb 0xbf)
begin the file or data stream, TinyXML will read it as UTF-8. </li>
<li> If the declaration tag is read, and it has an encoding="UTF-8", then
TinyXML will read it as UTF-8. </li>
<li> If the declaration tag is read, and it has no encoding specified, then TinyXML will
read it as UTF-8. </li>
<li> If the declaration tag is read, and it has an encoding="something else", then TinyXML
will read it as Legacy Mode. In legacy mode, TinyXML will work as it did before. It's
not clear what that mode does exactly, but old content should keep working.</li>
<li> Until one of the above criteria is met, TinyXML runs in Legacy Mode.</li>
</ol>
What happens if the encoding is incorrectly set or detected? TinyXML will try
to read and pass through text seen as improperly encoded. You may get some strange results or
mangled characters. You may want to force TinyXML to the correct mode.
You may force TinyXML to Legacy Mode by using LoadFile( TIXML_ENCODING_LEGACY ) or
LoadFile( filename, TIXML_ENCODING_LEGACY ). You may force it to use legacy mode all
the time by setting TIXML_DEFAULT_ENCODING = TIXML_ENCODING_LEGACY. Likewise, you may
force it to TIXML_ENCODING_UTF8 with the same technique.
For English users, using English XML, UTF-8 is the same as low-ASCII. You
don't need to be aware of UTF-8 or change your code in any way. You can think
of UTF-8 as a "superset" of ASCII.
UTF-8 is not a double byte format - but it is a standard encoding of Unicode!
TinyXML does not use or directly support wchar, TCHAR, or Microsoft's _UNICODE at this time.
It is common to see the term "Unicode" improperly refer to UTF-16, a wide byte encoding
of unicode. This is a source of confusion.
For "high-ascii" languages - everything not English, pretty much - TinyXML can
handle all languages, at the same time, as long as the XML is encoded
in UTF-8. That can be a little tricky, older programs and operating systems
tend to use the "default" or "traditional" code page. Many apps (and almost all
modern ones) can output UTF-8, but older or stubborn (or just broken) ones
still output text in the default code page.
For example, Japanese systems traditionally use SHIFT-JIS encoding.
Text encoded as SHIFT-JIS can not be read by TinyXML.
A good text editor can import SHIFT-JIS and then save as UTF-8.
The <a href="http://skew.org/xml/tutorial/">Skew.org link</a> does a great
job covering the encoding issue.
The test file "utf8test.xml" is an XML containing English, Spanish, Russian,
and Simplified Chinese. (Hopefully they are translated correctly). The file
"utf8test.gif" is a screen capture of the XML file, rendered in IE. Note that
if you don't have the correct fonts (Simplified Chinese or Russian) on your
system, you won't see output that matches the GIF file even if you can parse
it correctly. Also note that (at least on my Windows machine) console output
is in a Western code page, so that Print() or printf() cannot correctly display
the file. This is not a bug in TinyXML - just an OS issue. No data is lost or
destroyed by TinyXML. The console just doesn't render UTF-8.
<h3> Entities </h3>
TinyXML recognizes the pre-defined "character entities", meaning special
characters. Namely:
@verbatim
&amp; &
&lt; <
&gt; >
&quot; "
&apos; '
@endverbatim
These are recognized when the XML document is read, and translated to there
UTF-8 equivalents. For instance, text with the XML of:
@verbatim
Far &amp; Away
@endverbatim
will have the Value() of "Far & Away" when queried from the TiXmlText object,
and will be written back to the XML stream/file as an ampersand. Older versions
of TinyXML "preserved" character entities, but the newer versions will translate
them into characters.
Additionally, any character can be specified by its Unicode code point:
The syntax "&#xA0;" or "&#160;" are both to the non-breaking space characher.
<h3> Printing </h3>
TinyXML can print output in several different ways that all have strengths and limitations.
- Print( FILE* ). Output to a std-C stream, which includes all C files as well as stdout.
- "Pretty prints", but you don't have control over printing options.
- The output is streamed directly to the FILE object, so there is no memory overhead
in the TinyXML code.
- used by Print() and SaveFile()
- operator<<. Output to a c++ stream.
- Integrates with standart C++ iostreams.
- Outputs in "network printing" mode without line breaks. Good for network transmission
and moving XML between C++ objects, but hard for a human to read.
- TiXmlPrinter. Output to a std::string or memory buffer.
- API is less concise
- Future printing options will be put here.
- Printing may change slightly in future versions as it is refined and expanded.
<h3> Streams </h3>
With TIXML_USE_STL on TinyXML supports C++ streams (operator <<,>>) streams as well
as C (FILE*) streams. There are some differences that you may need to be aware of.
C style output:
- based on FILE*
- the Print() and SaveFile() methods
Generates formatted output, with plenty of white space, intended to be as
human-readable as possible. They are very fast, and tolerant of ill formed
XML documents. For example, an XML document that contains 2 root elements
and 2 declarations, will still print.
C style input:
- based on FILE*
- the Parse() and LoadFile() methods
A fast, tolerant read. Use whenever you don't need the C++ streams.
C++ style output:
- based on std::ostream
- operator<<
Generates condensed output, intended for network transmission rather than
readability. Depending on your system's implementation of the ostream class,
these may be somewhat slower. (Or may not.) Not tolerant of ill formed XML:
a document should contain the correct one root element. Additional root level
elements will not be streamed out.
C++ style input:
- based on std::istream
- operator>>
Reads XML from a stream, making it useful for network transmission. The tricky
part is knowing when the XML document is complete, since there will almost
certainly be other data in the stream. TinyXML will assume the XML data is
complete after it reads the root element. Put another way, documents that
are ill-constructed with more than one root element will not read correctly.
Also note that operator>> is somewhat slower than Parse, due to both
implementation of the STL and limitations of TinyXML.
<h3> White space </h3>
The world simply does not agree on whether white space should be kept, or condensed.
For example, pretend the '_' is a space, and look at "Hello____world". HTML, and
at least some XML parsers, will interpret this as "Hello_world". They condense white
space. Some XML parsers do not, and will leave it as "Hello____world". (Remember
to keep pretending the _ is a space.) Others suggest that __Hello___world__ should become
Hello___world.
It's an issue that hasn't been resolved to my satisfaction. TinyXML supports the
first 2 approaches. Call TiXmlBase::SetCondenseWhiteSpace( bool ) to set the desired behavior.
The default is to condense white space.
If you change the default, you should call TiXmlBase::SetCondenseWhiteSpace( bool )
before making any calls to Parse XML data, and I don't recommend changing it after
it has been set.
<h3> Handles </h3>
Where browsing an XML document in a robust way, it is important to check
for null returns from method calls. An error safe implementation can
generate a lot of code like:
@verbatim
TiXmlElement* root = document.FirstChildElement( "Document" );
if ( root )
{
TiXmlElement* element = root->FirstChildElement( "Element" );
if ( element )
{
TiXmlElement* child = element->FirstChildElement( "Child" );
if ( child )
{
TiXmlElement* child2 = child->NextSiblingElement( "Child" );
if ( child2 )
{
// Finally do something useful.
@endverbatim
Handles have been introduced to clean this up. Using the TiXmlHandle class,
the previous code reduces to:
@verbatim
TiXmlHandle docHandle( &document );
TiXmlElement* child2 = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).Child( "Child", 1 ).ToElement();
if ( child2 )
{
// do something useful
@endverbatim
Which is much easier to deal with. See TiXmlHandle for more information.
<h3> Row and Column tracking </h3>
Being able to track nodes and attributes back to their origin location
in source files can be very important for some applications. Additionally,
knowing where parsing errors occured in the original source can be very
time saving.
TinyXML can tracks the row and column origin of all nodes and attributes
in a text file. The TiXmlBase::Row() and TiXmlBase::Column() methods return
the origin of the node in the source text. The correct tabs can be
configured in TiXmlDocument::SetTabSize().
<h2> Using and Installing </h2>
To Compile and Run xmltest:
A Linux Makefile and a Windows Visual C++ .dsw file is provided.
Simply compile and run. It will write the file demotest.xml to your
disk and generate output on the screen. It also tests walking the
DOM by printing out the number of nodes found using different
techniques.
The Linux makefile is very generic and runs on many systems - it
is currently tested on mingw and
MacOSX. You do not need to run 'make depend'. The dependecies have been
hard coded.
<h3>Windows project file for VC6</h3>
<ul>
<li>tinyxml: tinyxml library, non-STL </li>
<li>tinyxmlSTL: tinyxml library, STL </li>
<li>tinyXmlTest: test app, non-STL </li>
<li>tinyXmlTestSTL: test app, STL </li>
</ul>
<h3>Makefile</h3>
At the top of the makefile you can set:
PROFILE, DEBUG, and TINYXML_USE_STL. Details (such that they are) are in
the makefile.
In the tinyxml directory, type "make clean" then "make". The executable
file 'xmltest' will be created.
<h3>To Use in an Application:</h3>
Add tinyxml.cpp, tinyxml.h, tinyxmlerror.cpp, tinyxmlparser.cpp, tinystr.cpp, and tinystr.h to your
project or make file. That's it! It should compile on any reasonably
compliant C++ system. You do not need to enable exceptions or
RTTI for TinyXML.
<h2> How TinyXML works. </h2>
An example is probably the best way to go. Take:
@verbatim
<?xml version="1.0" standalone=no>
<!-- Our to do list data -->
<ToDo>
<Item priority="1"> Go to the <bold>Toy store!</bold></Item>
<Item priority="2"> Do bills</Item>
</ToDo>
@endverbatim
Its not much of a To Do list, but it will do. To read this file
(say "demo.xml") you would create a document, and parse it in:
@verbatim
TiXmlDocument doc( "demo.xml" );
doc.LoadFile();
@endverbatim
And its ready to go. Now lets look at some lines and how they
relate to the DOM.
@verbatim
<?xml version="1.0" standalone=no>
@endverbatim
The first line is a declaration, and gets turned into the
TiXmlDeclaration class. It will be the first child of the
document node.
This is the only directive/special tag parsed by TinyXML.
Generally directive tags are stored in TiXmlUnknown so the
commands wont be lost when it is saved back to disk.
@verbatim
<!-- Our to do list data -->
@endverbatim
A comment. Will become a TiXmlComment object.
@verbatim
<ToDo>
@endverbatim
The "ToDo" tag defines a TiXmlElement object. This one does not have
any attributes, but does contain 2 other elements.
@verbatim
<Item priority="1">
@endverbatim
Creates another TiXmlElement which is a child of the "ToDo" element.
This element has 1 attribute, with the name "priority" and the value
"1".
@verbatim
Go to the
@endverbatim
A TiXmlText. This is a leaf node and cannot contain other nodes.
It is a child of the "Item" TiXmlElement.
@verbatim
<bold>
@endverbatim
Another TiXmlElement, this one a child of the "Item" element.
Etc.
Looking at the entire object tree, you end up with:
@verbatim
TiXmlDocument "demo.xml"
TiXmlDeclaration "version='1.0'" "standalone=no"
TiXmlComment " Our to do list data"
TiXmlElement "ToDo"
TiXmlElement "Item" Attribtutes: priority = 1
TiXmlText "Go to the "
TiXmlElement "bold"
TiXmlText "Toy store!"
TiXmlElement "Item" Attributes: priority=2
TiXmlText "Do bills"
@endverbatim

////////////////////////////////////////////////////////
// Acknowledgements:
// Thanks to Adam Szulc for his initial CString code.
////////////////////////////////////////////////////////
// cstring.h
// Declaration of the cstring.h
// This class is intended to provide a simple alternative to the MFC/ATL
// CString class that ships with Microsoft compilers. The CString class
// specified here is compatible with other compilers such as Borland 5.5
// and MinGW.
// Differences between this class and the MFC/ATL CString class
// ------------------------------------------------------------
// 1) The constructors for this class accepts only TCHARs. The various text conversion
// functions can be used to convert from other character types to TCHARs.
//
// 2) This class is not reference counted, so these CStrings should be passed as
// references or const references when used as function arguments. As a result there
// is no need for functions like LockBuffer and UnLockBuffer.
//
// 3) The Format functions only accepts POD (Plain Old Data) arguments. It does not
// accept arguments which are class or struct objects. In particular it does not
// accept CString objects, unless these are cast to LPCTSTR.
// This is demonstrates valid and invalid usage:
// CString string1(_T("Hello World"));
// CString string2;
//
// // This is invalid, and produces undefined behaviour.
// string2.Format(_T("String1 is: %s"), string1); // No! you can't do this
//
// // This is ok
// string2.Format(_T("String1 is: %s"), (LPCTSTR)string1); // Yes, this is correct
//
// Note: The MFC/ATL CString class uses a non portable hack to make its CString class
// behave like a POD. Other compilers (such as the MinGW compiler) specifically
// prohibit the use of non POD types for functions with variable argument lists.
//
// 4) This class provides a few additional functions:
// b_str Returns a BSTR string. This an an alternative for casting to BSTR.
// c_str Returns a const TCHAR string. This is an alternative for casting to LPCTSTR.
// GetErrorString Assigns CString to the error string for the specified System Error Code
// (from ::GetLastErrror() for example).
// GetString Returns a reference to the underlying std::basic_string<TCHAR>. This
// reference can be used to modify the string directly.

//
// * Users of Win32++ are advised to begin their resource IDs from 120 to
// allow for possible expansion of Win32++.

// are special window types such as buttons, edit controls, tree views,
// list views, static text etc.
// The layout of a dialog is typically defined in a resource script file
// (often Resource.rc). While this script file can be constructed manually,
// it is often created using a resource editor. If your compiler doesn't
// include a resource editor, you might find ResEdit useful. It is a free
// resource editor available for download at:
// http://www.resedit.net/
// CDialog supports modal and modeless dialogs. It also supports the creation
// of dialogs defined in a resource script file, as well as those defined in
// a dialog template.
// Use the Dialog generic program as the starting point for your own dialog
// applications.
// The DlgSubclass sample demonstrates how to use subclassing to customise
// the behaviour of common controls in a dialog.

jpg | A jpeg resource file
ico | An icon resource file
bmp | A bitmap resource file
cur | A cursor resource file
manifest | A manifest resource file
txt | A text file
xml | An Extensible Markup Language file (defines the ribbon UI)
Supported Compilers and Integrated Development Environments (IDEs)
==================================================================
Win32++ supports the following:
* Borland Compiler Version 5.5
* Borland Developer Studio 2006
* Borland Turbo C++ 2006
* CodeBlocks
* Dev-C++
* MinGW GCC Compiler
* Visual Studio 6
* Visual Studio.net 2003
* Visual C++ Toolkit 2003
* Visual Studio.net 2005
* Visual Studio.net 2005 Express
* Visual Studio.net 2008
* Visual Studio.net 2008 Express
* Visual Studio.net 2010
CodeBlocks is an IDE. The project files are configured for the following
compilers:
* Borland Compiler Version 5.5
* MinGW GNU compiler
* Visual C++ Toolkit 2003
Dev-C++ is an IDE which supports the MinGW GNU compiler
Supported Operating Systems
===========================
The programs compiled with Win32++ can run on the following operating systems:
* Win95 (all versions, with or without Internet Explorer 4 installed)
* Win98 (both versions)
* WinME
* Windows NT 4
* Windows 2000
* Windows XP
* Windows XP x64
* Windows Vista
* Windows Vista x64
* Windows 7
* Windows 7 x64
* Windows Server 2003
* Windows Server 2003 x64
* Windows Server 2008
* Windows Server 2008 x64
* Windows CE
Note: Programs compiled with Visual Studio.net 2008 and Visual Studio.net 2008
Express will not run on Win32 operating systems earlier than Windows 2000.
Win32++ automatically detects if the operating system is capable of using
rebars. If rebars are not supported by the OS, Win32++ produces a frame without
rebars.
Win32++ is Unicode compliant and can therefore be used to develop Unicode
applications. Users are advised that older operating systems (namely Win95,
Win98 and WinME) don't support Unicode applications.
Win32++ supports 64bit compilers, and can be used to develop 64bit code.
Directory Structure
===================
When extracting the files from the zip archive, be sure to preserve the
directory structure. The directory structure will typically look like this:
.\include
.\new projects
.\output
.\samples
.\tools
.\tutorials
.\WCE samples
The files which form the Win32++ library are contained in the include
subdirectory.

// mdi.h
// Declaration of the CMDIChild and CMDIFrame classes
// The classes defined here add MDI frames support to Win32++. MDI
// (Multiple Document Interface) frames host one or more child windows. The
// child windows hosted by a MDI frame can be different types. For example,
// some MDI child windows could be used to edit text, while others could be
// used to display a bitmap. Four classes are defined here to support MDI
// frames:
// 1) CMDIFrame. This class inherits from CFrame, and adds the functionality
// required by MDI frames. It keeps track of the MDI children created and
// destroyed, and adjusts the menu when a MDI child is activated. Use the
// AddMDIChild function to add MDI child windows to the MDI frame. Inherit
// from CMDIFrame to create your own MDI frame.
//
// 2) CMDIChild: All MDI child windows (ie. CWnd classes) should inherit from
// this class. Each MDI child type can have a different frame menu.
// Use the MDIFrame generic application as the starting point for your own MDI
// frame applications.
// Refer to the MDIDemo sample for an example on how to use these classes to
// create a MDI frame application with different types of MDI child windows.

// menu.h
// Declaration of the CMenu class
// Notes
// 1) Owner-drawn menus send the WM_MEASUREITEM and WM_DRAWITEM messages
// to the window that owns the menu. To manage owner drawing for menus,
// handle these two messages in the CWnd's WndProc function.
//
// 2) The CMenu pointer returned by FromHandle might be a temporary pointer. It
// should be used immediately, not saved for later use.
//
// 3) The CMenu pointers returned by FromHandle or GetSubMenu do not need
// to be deleted. They are automatically deleted by the Win32++.
//
// 4) CMenu pointers returned by GetSubMenu are deleted when the parent CMenu is
// detached, destroyed or deconstructed.
//
// 5) The HMENU that is attached to a CMenu object (using the attach function) is
// automatically deleted when the CMenu object goes out of scope. Detach the
// HMENU to stop it being deleted when CMenu's destructor is called.
//
// 6) Pass CMenu objects by reference or by pointer when passing them as function
// arguments.
//
// 7) In those functions that use a MENUITEMINFO structure, its cbSize member is
// automatically set to the correct value.
// Program sample
// --------------
// void CView::CreatePopup()
// {
// CPoint pt = GetCursorPos();
//
// // Create the menu
// CMenu Popup;

About Win32++
-------------
Win32++ is simple and easy to understand framework for developing Win32
applications using C++. It brings an object oriented approach to programming
directly with the Win32 API. Each window created is a C++ class object capable
of having its own window procedure for routing messages.
Win32++ supports the following compilers and development environments:
* Borland C++ Compiler 5.5
* Borland Developer Studio 2006
* Dev-C++
* Microsoft Visual C++ Toolkit 2003
* Microsoft Visual C++ 2005 Express Edition
* Microsoft Visual C++ 2008 Express Edition
* Microsoft Visual C++ 2010 Express Edition
* Microsoft Visual Studio 6.0
* Microsoft Visual Studio.net 2003
* Microsoft Visual Studio.net 2005
* Microsoft Visual Studio.net 2008
* Microsoft Visual Studio.net 2010
* MinGW compiler
Win32++ supports the following operating systems
* Windows 95
* Windows 98
* Windows ME
* Windows NT 4
* Windows 2000
* Windows XP (32bit and 64bit)
* Windows 2003 Server (32bit and 64bit)
* Windows Vista (32bit and 64bit)
* Windows 2008 Server (32bit and 64bit)
* Windows 7 (32 bit and 64 bit)
* Windows CE from WCE400 (Windows mobile 2003) to WCE600 (Windows mobile 6)
Features
--------
Win32++ code has the following features
* Object Orientated
* Subclassing support
* Notification reflection and message reflection
* Unicode compliant, with multilingual support
* Multi-threaded support.
* Tracing
* 64 bit support
* Windows 7 ribbon support
* Themes support
* Network support (including IP version 6)
* Docking windows
* Tabbed MDIs
Frames produced by Win32++ include the following:
* Rebar
* Menubar
* Toolbar
* Status bar
* Tool tips

//
// This software was developed from code available in the public domain
// and has no copyright.
// About Shared_Ptr:
// Shared_Ptr wraps a reference-counted smart pointer around a dynamically
// allocated object. Unlike auto_ptr, the Shared_Ptr can be used as a smart
// pointer for objects stored in containers like std::vector. Do not use
// Shared_Ptr (or shared_ptr or auto_ptr) for dynamically allocated arrays.
// See below for advice on how to wrap dynamically allocated arrays in a
// vector.
//
// The next standard of C++ will also contain a shared_ptr. Some modern
// compilers already have a shared_ptr available as std::tr1::shared_ptr. If
// your compiler already provides a shared_ptr, or if you have Boost, you
// should use that smart pointer instead. This class has been provided for
// those users who don't have easy access to an "official" shared_ptr.
// Note that this class is "Shared_Ptr", a slightly different name to the
// future "shared_ptr" to avoid naming conflicts.
// Advantages of Shared_Ptr (or shared_ptr where available):
// - Shared_Ptr can be safely copied. This makes then suitable for containers.
// - Shared_Ptr automatically calls delete for the wrapped pointer when
// its last copy goes out of scope.
// - Shared_Ptr simplifies exception safety.
//
// Without smart pointers, it can be quite challenging to ensure that every
// dynamically allocated pointer (i.e. use of new) is deleted in the event of
// all possible exceptions. In addition to the exceptions we throw ourselves,
// "new" itself will throw an exception it it fails, as does the STL (Standard
// Template Library which includes vector and string). Without smart pointers
// we often need to resort to additional try/catch blocks simply to avoid
// memory leaks when exceptions occur.
// Examples:
// Shared_Ptr<CWnd> w1(new CWnd);
// or
// Shared_Ptr<CWnd> w1 = new CWnd;
// or
// typedef Shared_Ptr<CWnd> CWndPtr;
// CWndPtr w1 = new CWnd;
// or
// typedef Shared_Ptr<CWnd> CWndPtr;
// CWndPtr w1(new CWnd);
//
// And with a vector
// typedef Shared_Ptr<CWnd> CWndPtr;
// std::vector<CWndPtr> MyVector;
// MyVector.push_back(new CWnd);
// or
// typedef Shared_Ptr<CWnd> CWndPtr;
// CWnd* pWnd = new CWnd;
// std::vector<CWndPtr> MyVector;
// MyVector.push_back(pWnd);
//
// How to handle dynamically allocated arrays:
// While we could create a smart pointer for arrays, we don't need to because
// std::vector already handles this for us. Consider the following example:
// int nLength = ::GetWindowTextLength(m_hWnd);
// pTChar = new TCHAR[nLength+1];
// memset(pTChar, 0, (nLength+1)*sizeof(TCHAR));
// ::GetWindowText(m_hWnd, m_pTChar, nLength+1);
// ....
// delete[] pTChar;
//
// This can be improved by using a vector instead of an array
// int nLength = ::GetWindowTextLength(m_hWnd);
// std::vector<TCHAR> vTChar( nLength+1, _T('\0') );
// TCHAR* pTCharArray = &vTChar.front();
// ::GetWindowText(m_hWnd, pTCharArray, nLength+1);
//
// This works because the memory in a vector is always contiguous. Note that
// this is NOT always true of std::string.
// Summing up:
// In my opinion, "naked" pointers for dynamically created objects should be
// avoided in modern C++ code. That's to say that calls to "new" should be
// wrapped in some sort of smart pointer wherever possible. This eliminates
// the possibility of memory leaks (particularly in the event of exceptions).
// It also elminiates the need for delete in user's code.

// socket.h
// Declaration of the CSocket class
//
// The CSocket class represents a network socket. It encapsualtes many of
// the Windows Socket SPI fuctions, providing an object-oriented approach
// to network programming. After StartEvents is called, CSocket monitors
// the socket and responds automatically to network events. This event
// monitoring, for example, automatically calls OnReceive when there is
// data on the socket to be read, and OnAccept when a server should accept
// a connection from a client.
// Users of this class should be aware that functions like OnReceive,
// OnAccept, etc. are called on a different thread from the one CSocket is
// instanciated on. The thread for these functions needs to respond quickly
// to other network events, so it shouldn't be delayed. It also doesn't run
// a message loop, so it can't be used to create windows. For these reasons
// it might be best to use PostMessage in response to these functions in a
// windows environment.
// Refer to the network samples for an example of how to use this class to
// create a TCP client & server, and a UDP client and server.
// To compile programs with CSocket, link with ws3_32.lib for Win32,
// and ws2.lib for Windows CE. Windows 95 systems will need to install the
// "Windows Sockets 2.0 for Windows 95". It's available from:
// http://support.microsoft.com/kb/182108/EN-US/
// For a TCP server, inherit a class from CSocket and override OnAccept, OnDisconnect
// and OnRecieve. Create one instance of this class and use it as a listening socket.
// The purpose of the listening socket is to detect connections from clients and accept them.
// For the listening socket, we do the following:
// 1) Create the socket.
// 2) Bind an IP address to the socket.
// 3) Listen on the socket for incoming connection requests.
// 4) Use StartNotifyRevents to receive notification of network events.
// 5) Override OnAccept to accept requests on a newly created data CSocket object.
// 6) Create a new data socket for each client connection accepted.
// 7) The server socket uses the 'accept' function to accept an incoming connection
// from this new data socket.
// The purpose of the data socket is to send data to, and recieve data from the client.
// There will be one data socket for each client accepted by the server.
// To use it we do the following:
// * To recieve data from the client, override OnReceive and use Receive.
// * To send data to use Send.
// * OnDisconnect can be used to detect when the client is disconnected.
// For a TCP client, inherit from CSocket and override OnReceive and OnDisconnect.
// Create an instance of this inherited class, and perform the following steps:
// 1) Create the socket.
// 2) Connect to the server.
// 3) Use StartNotifyRevents to receive notification of network events.
// We are now ready to send and recieve data from the server.
// * Use Send to send data to the server.
// * Override OnReceive and use Recieve to receive data from the server
// * OnDisconnect can be used to detect when the client is disconnected from the server.
// Notes regarding IPv6 support
// * IPv6 is supported on Windows Vista and above. Windows XP with SP2 provides
// "experimental" support, which can be enabled by entering "ipv6 install"
// at a command prompt.
// * IPv6 is not supported by all compilters and devlopment environments. In
// particular, it is not supported by Dev-C++ or Borland 5.5. A modern
// Platform SDK needs to be added to Visual Studio 6 for it to support IPv6.
// * IsIPV6Supported returns false if either the operating system or the
// development environment fails to support IPv6.

////////////////////////////////////////////////////////
// The CThread class simplifies the use of threads with Win32++.
// To use threads in your Win32++ application, inherit a class from
// CThread, and override InitInstance. When your class is instanciated,
// a new thread is started, and the InitInstance function is called to
// run in the new thread.
// If your thread is used to run one or more windows, InitInstance should
// return TRUE, causing the MessageLoop function to be called. If your
// thread doesn't require a MessageLoop, it should return FALSE. Threads
// which don't run a message loop as sometimes referred to as "worker" threads.
// Note: It is your job to end the thread before CThread ends!
// To end a thread with a message loop, use PostQuitMessage on the thread.
// To end a thread without a message loop, set an event, and end the thread
// when the event is received.
// Hint: It is never a good idea to use things like TerminateThread or ExitThread to
// end your thread. These represent poor programming techniques, and are likely
// to leak memory and resources.
// More Hints for thread programming:
// 1) Avoid using SendMessage between threads, as this will cause one thread to wait for
// the other to respond. Use PostMessage between threads to avoid this problem.
// 2) Access to variables and resources shared between threads need to be made thread safe.
// Having one thread modify a resouce or variable while another thread is accessing it is
// a recipe for disaster.
// 3) Thread Local Storage (TLS) can be used to replace global variables to make them thread
// safe. With TLS, each thread gets its own copy of the variable.
// 4) Critical Sections can be used to make shared resources thread safe.
// 5) Window messages (including user defined messages) can be posted between GUI threads to
// communicate information between them.
// 6) Events (created by CreateEvent) can be used to comunicate information between threads
// (both GUI and worker threads).
// 7) Avoid using sleep to synchronise threads. Generally speaking, the various wait
// functions (e.g. WaitForSingleObject) will be better for this.
// About Threads:
// Each program that executes has a "process" allocated to it. A process has one or more
// threads. Threads run independantly of each other. It is the job of the operating system
// to manage the running of the threads, and do the task switching between threads as required.
// Systems with multiple CPUs will be able to run as many threads simultaneously as there are
// CPUs.
// Threads behave like a program within a program. When the main thread starts, the application
// runs the WinMain function and ends when WinMain ends. When another thread starts, it too
// will run the function provided to it, and end when that function ends.

// About different character and string types:
// ------------------------------------------
// char (or CHAR) character types are ANSI (8 bits).
// wchar_t (or WCHAR) character types are Unicode (16 bits).
// TCHAR characters are Unicode if the _UNICODE macro is defined, otherwise they are ANSI.
// BSTR (Basic String) is a type of string used in Visual Basic and COM programming.
// OLE is the same as WCHAR. It is used in Visual Basic and COM programming.
