c++ - Controls blanked using XP themes -
i have been learning win32 api, , have been stumped this:
when run on windows 7 in both "classic look" , "windows 7 aero glass" look, ok, , has aero on controls, normal appearance. when run on xp machine, again, "classic look", looks ok, when run on xp "windows xp theme", above get.
following microsoft's guidelines on visual styles @ http://msdn.microsoft.com/en-us/library/bb773175%28vs.85%29.aspx there 3 things needed do:
1 . link comctl32.lib , call initcommoncontrols.
check, did this, added comctl32 linker settings.
2 . add file called yourapp.exe.manifest source tree has xml manifest format.
check, did this. had version using, safe, tried version suggested on site, renamed started specified cover bases. (yes, know give name of application....)
3 . add manifest application's resource file follows:
check, did this. added specified line suggest rc file.
so, under conditions, works, except windows xp style theme.
the thing thinking remains somehow not responding wm_paint message, passing default window proc, allow windows thing in regard. (i couldn't see if wasn't working, wouldn't work anywhere else.)
i saw similar post post, , said use initcommoncontrolsex, did too, no avail.
i stumped.

if want remove black background of controls, can try enablethemedialogtexture().
the second method(from correctly drawn themed dialogs in winxp):
// wm_initdialog rect rc; getwindowrect(hwnd,&rc); hdc hdc=getdc(hwnd); hdc hdcmem=createcompatibledc(hdc); hbitmap hbmp=createcompatiblebitmap(hdc,rc.right-rc.left,rc.bottom-rc.top); hbitmap hbmpold=(hbitmap)selectobject(hdcmem,hbmp); sendmessage(hwnd,wm_printclient,(wparam)hdcmem,(lparam)(prf_erasebkgnd|prf_client|prf_nonclient)); hbrush=createpatternbrush(hbmp); // hbrush hbrush global selectobject(hdcmem,hbmpold); deleteobject(hbmp); deletedc(hdcmem); releasedc(hwnd,hdc); //wm_ctlcolorstatic rect rc; setbkmode((hdc)wparam,transparent); getwindowrect((hwnd)lparam,&rc); mapwindowpoints(null,hwnd,(lppoint)&rc,2); setbrushorgex((hdc)(wparam),-rc.left,-rc.top,null); return (lresult)hbrush;
