DirectX9 FullScreen Issues

[InfernoTK]

I'm new to Windows programming and DirectX, but I feel I'm moving along at a good pace, but I seem to have hit a wall. I just learned about fullscreen mode with DirectX, and I successfully programmed a working program that just drew a rectangle the size of the screen that constantly changed colors. Now I am trying to make a program that draws a rectangle of random size, randomly on the screen, and then have it bounce around the screen without going off (while changing its color). This program works 100% in windowed mode, but in fullscreen mode I get an error when the Direct3D Device is trying to be created... here is the code (for fullscreen mode, only thing i change between fullscreen and windowed mode is the d3dpp.windowed = true/false);

here is the code...

Try running with the DirectX debugging applet. It should point out any errors you may have.
