Well, actually I've seen demo-applications which spawn new windows of the same instance (the same process) but have different taskbar groups. But I want to do the inverse thing ^^ (well, this demo was for the ITaskBar3 object introduced in Windows 7, but I'm pretty sure this is already possible with the legacy taskbar).
Anyway, I've already tried SetParent. But this wasn't what I've looked for, if I use "SetParent(hWnd,My_Application_Window)" the Engine window is "inside" my application. So that won't work for me.
Any other ideas would be great
