Why not GetWindowText()?

Do you know there is a GetWindowText() API call?
In any event, here is a homemade GetWindowText(), which uses SendMessage() and WM_GETTEXT, as you requested (it is also using the string object from STL:
std::string GetWindowText( HWND wnd )
{
std::string text;
WPARAM length = SendMessage( wnd, WM_GETTEXTLENGTH, 0, 0 );
if( length > 0 )
{
char *buffy = new char [length+1];
LRESULT got = SendMessage( wnd, WM_GETTEXT, length+1, (LPARAM)buffy );
if( (LRESULT)length == got )
text = buffy;
delete [] buffy;
}
return text;
}
(sorry about the lack of formatting; it looks like the tags support in the forum is temporarily not working)
