Harold, I found a way to hide a window from appearing in taskbar when it is visible.
The technique I used was showing the window as a dialog with parent as MS-Windows
desktop
desktophwnd=GetDesktopWindow();
int ret = DialogBox(GetModuleHandle(NULL),
MAKEINTRESOURCE(IDD_ABOUT), desktophwnd, AboutDlgProc);
Where "about" window wont appear in taskbar.
Also it wont be a modal window.
To make it more convincing I hide the calling window.
I am attaching the example
While running, do "Tools\About" from the menu
So will it be possible to use this with "XWin.exe -nodecoration"
cheers
