That's possible Esper. But very limited, you would also need a .ini file for the path of the game. Because the startup.exe would not know where the game is and what the name is, because all the startup.exe does is run a file by a given path and then retrieve the HWND of it, send messages to that HWND in a loop with the HWND of the startup.exe, as soon as the lite-c application catches it I can terminate the startup.exe cause it just retrieved the HWND of the startup.exe.

What if you wanted to have a button, or two. What if you wanted to have an animation of a logo. Or something moveing around in the window, custom cursor, music for background, sounds for the buttons. All these are possible in WinForms with .NET in visual studio 2008.
