Hi all, I'm working my way through Jonathan Harbour's Beginning Game Programming - everything was going great until I hit the end of chapter 5 - where you create a full screen window. The windowed mode worked fine but when I made the changes to the code and ran it in fullscreen mode all that happens is a white rectangle appears (it's size depends on the width and height parameters) and hitting escape does nothing. I also did the first part of chapter 6 which is supposed to have the moving rectangle around the window - but nothing... same white rectangle. I'm not getting any errors - anyone have any ideas? I should mention I have Vista - and fairly new computer (about a year old) - video card is gforce 8800... I guess I should insert the code...

Please post the topic onto the correct category.

Which is? My difficulties are with Directx - this seemed like the right category...

Anyone else have any ideas?

In your WinMain function right before entering the main loop you forgot to call Game_Init.

Thank You very much!! That was exactly the problem!
