I am using Visual Basic and DirectX to create my application. I want to blit a black background to the screen so that if no other images are being blitted, the user only sees black. I have an ongoing loop, with the following code. However, the black isn't appearing. Do you know why? Or how else could I do this? Does the backbuffer have some sort of attribute that will make it black at all times? Currently, if I am not blitting an image, I can just see my VB form in the newly set resolution. Code: ----- rBack.Left = 0 rBack.Right = mScreenWidth rBack.Top = 0 rBack.Bottom = mScreenHeight ddrval = backbuffer.BltColorFill(rBack, vbBlack) 'flip the back buffer to the screen primary.Flip Nothing, DDFLIP_WAIT ----- Please help me.

trace out the "ddrval" you get from BltColorFill() an look it up in the SDK.
