<h3><a name="platforms">Which Windows platforms are supported?</a></h3>
wxWindows 2 can be used to develop and deliver applications on Windows 3.1, Win32s,
-Windows 95, Windows 98, and Windows NT. A Windows CE version is being looked into (see below).<P>
+Windows 95, Windows 98, Windows NT, Windows 2000, and Windows XP. A Windows CE
+version is being looked into (see below).<P>
wxWindows 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
the statically-linked 'minimal' sample), shoehorning wxWindows 2 into a Windows CE device's limited
storage should not be a problem.<P>
+<h3><a name="winxp">What do I need to do for Windows XP?</a></h3>
+
+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:
+
+<pre>
+<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
+<assembly
+ xmlns="urn:schemas-microsoft-com:asm.v1"
+ manifestVersion="1.0">
+<assemblyIdentity
+ processorArchitecture="x86"
+ version="5.1.0.0"
+ type="win32"
+ name="foo.exe"/>
+ <description>Foo program</description>
+ <dependency>
+ <dependentAssembly>
+ <assemblyIdentity
+ type="win32"
+ name="Microsoft.Windows.Common-Controls"
+ version="6.0.0.0"
+ publicKeyToken="6595b64144ccf1df"
+ language="*"
+ processorArchitecture="x86"/>
+ </dependentAssembly>
+ </dependency>
+</assembly>
+</pre>
+
<h3><a name="compilers">What compilers are supported?</a></h3>
Please see the wxWindows 2 for Windows install.txt file for up-to-date information, but
Yes, Unicode is fully supported under Windows NT/2000 (Windows 9x don't
have Unicode support anyhow).
+<h3><a name="doublebyte">Does wxWindows support double byte fonts (Chinese/Japanese/Korean etc.)?</a></h3>
+
+An answer from <a href="mailto:goedde@logosoft.de">Klaus Goedde</a>:<p>
+
+"For Japanese under Win2000, it seems that wxWindows has no problems to work with double byte char sets
+(I mean DBCS, that's not Unicode). First you have to install Japanese support on your Win2K system
+and choose for ANSI translation
+HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\CodePage=932 (default is 1252 for Western).
+Then you can see all the funny Japanese letters under wxWindows too.<P>
+
+In a wxTextCtrl control you have to set the window style "wxTE_RICH", otherwise this control shows the wrong
+letters.
+
+I don't now whether it works on non W2K systems, because I'm just starting using wxWindows."
+<P>
+
<h3><a name="dll">Can you compile wxWindows 2 as a DLL?</a></h3>
Yes (using the Visual C++ or Borland C++ makefile), but be aware that distributing DLLs is a thorny issue
by your application. So for example, the 'minimal' sample is less than 300KB using VC++ 6.<P>
If you want to distribute really small executables, you can
-use <a href="http://www.icl.ndirect.co.uk/petite/" target=_top>Petite</a>
+use <a href="http://www.un4seen.com/petite/" target=_top>Petite</a>
by Ian Luck. This nifty utility compresses Windows executables by around 50%, so your 500KB executable
will shrink to a mere 250KB. With this sort of size, there is reduced incentive to
-use DLLs.<P>
+use DLLs. Another good compression tool is <a href="http://upx.sourceforge.net/" target=_top>UPX</a>.
+<P>
<H3><a name="mfc">Is wxWindows compatible with MFC?</a></H3>
application. However, don't expect to be able to enable wxWindows windows with OLE-2
functionality using MFC.<P>
+<H3><a name="asuffix">Why do I get errors about FooBarA when I only use FooBar in my program?</H3>
+
+If you get errors like
+<p>
+<center>
+<tt>no matching function for call to 'wxDC::DrawTextA(const char[5], int,
+int)'</tt>
+</center>
+<p>
+or similar ones for the other functions, i.e. the compiler error messages
+mention the function with the <tt>'A'</tt> suffix while you didn't
+use it in your code, the explanation is that you had included
+<tt><windows.h></tt> header which redefines many symbols to have such
+suffix (or <tt>'W'</tt> in the Unicode builds).
+
+<p>
+The fix is to either not include <tt><windows.h></tt> at all or include
+<tt>"wx/msw/winundef.h"</tt> immediately after it.
+
<H3><a name="newerrors">Why my code fails to compile with strange errors about new operator?</a></H3>
The most common cause of this problem is the memory debugging settings in
all keyboard input. You should ensure that event.Skip() is called for all input that
isn'used by the event handler.
+<H3><a name="#regconfig">Why can I not write to the HKLM part of the registry with wxRegConfig?</a></H3>
+
+Currently this is not possible because the wxConfig family of classes is
+supposed to deal with per-user application configuration data, and HKLM is
+only supposed to be writeable by a user with Administrator privileges. In theory,
+only installers should write to HKLM. This is still a point debated by the
+wxWindows developers. There are at least two ways to work around it if you really
+need to write to HKLM.<P>
+
+First, you can use wxRegKey directly, for example:
+
+<pre>
+ wxRegKey regKey;
+
+ wxString idName(wxT("HKEY_LOCAL_MACHINE\\SOFTWARE\\My Company\\My Product\\Stuff\\"));
+ idName += packid;
+
+ regKey.SetName(idName);
+
+ {
+ wxLogNull dummy;
+ if (!regKey.Create())
+ {
+ idName = wxT("HKEY_CURRENT_USER\\SOFTWARE\\My Company\\My Product\\Stuff\\");
+ idName += packid;
+ regKey.SetName(idName);
+ if (!regKey.Create())
+ return FALSE;
+ }
+ }
+
+ if (!regKey.SetValue(wxT("THING"), (long) thing)) err += 1;
+
+ regKey.Close();
+
+</pre>
+
+Or, you can employ this trick suggested by Istvan Kovacs:
+
+<pre>
+class myGlobalConfig : public wxConfig
+{
+ myGlobalConfig() :
+ wxConfig ("myApp", "myCompany", "", "", wxCONFIG_USE_GLOBAL_FILE)
+{};
+ bool Write(const wxString& key, const wxString& value);
+}
+
+bool myGlobalConfig::Write (const wxString& key, const wxString& value)
+{
+ wxString path = wxString ("SOFTWARE\\myCompany\\myApp\\") + wxPathOnly(key);
+ wxString new_path = path.Replace ("/", "\\", true);
+ wxString new_key = wxFileNameFromPath (key);
+ LocalKey().SetName (wxRegKey::HKLM, path);
+ return wxConfig::Write (new_key, value);
+}
+</pre>
