HELP W/ Device Contexts!!!

I am trying to set up a double buffering system for a program I am making so that I can draw images to a blank window without flicker. One problem!!! Lemme explain my code first, and then tell you the problem:

Code:

---

HDC prime, second;
HBITMAP hbmp;

prime = GetDC( hWnd );
second = CreateCompatibleDC( prime );
hbmp = CreateCompatibleBitmap( prime, wndWidth, wndHieght );
SelectObject( second, hbmp );
// Draw something on secondd here...
//
BitBlt( prime, 0, 0, wndWidth, wndHeight, second, 0, 0, SRCCOPY );

---

wndWidth and wndHeight are set to equal the width and height of the client rect, and hWnd is set to the window's handle.

My problem is: Whe i run the program the client rect is filled with all sorts of colors, looks like a mixed-up, jumbled picture of vc++ and my code!!! I even tried to set the DC to completely white first, but it doesnt work!!! I can still draw to the DC, but i can't figure out why its doing that. Does anyone know?

Does it only do it when you've *first started* the program? Try drawing a grey rectangle (filled) across the entire DC right after you've created it. Sounds like the memory isn't being reset properly somewhere (which it shouldn't be, I don't think).

I have tried that, not only with white, but with other colors. It's so wierd!!! I can draw anything on the DC but when I try to draw a rectangle the whole size of the window, it doesnt do anything!!! It just gives me that jumbled up picture.

Post the code.
