hDeviceWindow = 0xcccccccc

All my calls to d3d9->CreateDevice fail and return the error code D3DERR_INVALIDCALL. I used the de bugger and it think I have traced to problem to the D3DPRESENT_PARAMETERS structure. whenever I instanciate it, it's variable hDeviceWindow is set to 0xcccccccc, the value that the compiler assigns to variables that are not explicitly instanciated. I am fairly certain this is the cause of the problem, but I have no idea how to fix it. Here is my source code:

still need to do:

1. initilize sound system

2. initilize input system

3. add particle structure and .x file functions

note: I am sorry for all the unneccessary error checking. it was part of my trying to fix the bug (at that point i didn't know that my call to CreateDevice was failing).
