<h3><a name="platforms">Which Windows platforms are supported?</a></h3>
-wxWidgets 2 can be used to develop and deliver applications on Windows 3.1, Win32s,
-Windows 95, Windows 98, Windows NT, Windows 2000, and Windows XP. A Windows CE
-
version is being looked into (see below).<P>
+wxWidgets can be used to develop and deliver applications on Windows 95, Windows 98, Windows NT,
+Windows 2000, Windows XP, and Windows Vista. A Windows CE
+
port is also available (see below).<P>
-wxWidgets 2 is designed to make use of WIN32 features and controls. However, unlike Microsoft,
-we have not forgotten users of 16-bit Windows. Most features
-work under Windows 3.1, including wxTreeCtrl and wxListCtrl using the generic implementation.
-However, don't expect very Windows-95-specific classes to work, such as wxTaskBarIcon. The wxRegConfig
-class doesn't work either because the Windows 3.1 registry is very simplistic. Check out the 16-bit
-makefiles to see what other files have been left out.
-<P>
-16-bit compilation is supported under Visual C++ 1.5, and Borland BC++ 4 to 5.

+From wxWidgets 2.5, the XP manifest is included in wx/msw/wx.rc and
+so your application will be themed automatically so long as you include wx.rc
+in your own .rc file.<P>
+
+For versions of wxWidgets below 2.5, you need to provide the manifest
+explicitly, as follows.<p>
+
In the same directory as you have your executable (e.g. foo.exe) you
put a file called foo.exe.manifest in which you have something like
the following:
1 24 "winxp.manifest"
</PRE>
-In wxWidgets 2.5, this will be in the wx/msw/wx.rc and

good, it's very stable, the documentation is extensive, and it generates small executables.
Since project files are plain text, it's easy for me to generate appropriate project files
for wxWidgets samples.<P>

Yes (using the Visual C++ or Borland C++ makefile), but be aware that distributing DLLs is a thorny issue
and you may be better off compiling statically-linked applications, unless you're
docs/msw/install.txt for details. You may find that using configure instead
of makefile.g95 is easier, particularly since you can maintain debug and
release versions of the library simultaneously, in different directories.
-Also, run 'strip' after linking to remove all traces of debug info.

+<h3><a name="#dspfmt">Why does Visual C++ complain about corrupted project files?</a></h3>
If you have downloaded the wxWidgets sources from the cvs using a Unix cvs
client or downloaded a daily snapshot in <tt>.tar.gz</tt> format, it is likely
But the most important thing is to use the <strong>same</strong> CRT setting for
all components of your project.
+<h3><a name="#directx">Why do I get compilation errors when using wxWidgets with DirectShow?</a></h3>
+
+If you get errors when including Microsoft DirectShow or DirectDraw headers,
+the following message from Peter Whaite could help:
+<blockquote>
+> This causes compilation errors within DirectShow:
+>
+> wxutil.h(125) : error C2065: 'EXECUTE_ASSERT' : undeclared identifier
+> amfilter.h(1099) : error C2065: 'ASSERT' : undeclared identifier
+
+The reason for this is that __WXDEBUG__ is also used by the DXSDK (9.0
+in my case) to '#pragma once' the contents of
+DXSDK/Samples/C++/DirectShow/BaseClasses/wxdebug.h. So if __WXDEBUG__
+is defined, then wxdebug.h doesn't get included, and the assert macros
+don't get defined. You have to #undef __WXDEBUG__ before including the
+directshow baseclass's <streams.h>.
+</blockquote>
+
+
+<h3><a name="#handlewm">How do I handle Windows messages in my wxWidgets program?</a></h3>
+
+To handle a Windows message you need to override a virtual
+<tt>MSWWindowProc()</tt> method in a wxWindow-derived class. You should then
+test if <tt>nMsg</tt> parameter is the message you need to process and perform
+the necessary action if it is or call the base class method otherwise.
