Pixel Shading DDraw with HDC problem

Basically what I am trying to do is make sprites that have different color of ugly pink be able to be set to a specific rgb value before they are loaded as a surface into direct draw, this just saves me time so I only have to draw one set of sprites, I wrote something like this for vb and it worked, but I don''t see whats wrong here, this is called in ddutil in the function DDCopyBitmap() right after it calls: GetObject(hbm, sizeof(bm), &bm); dx = dx == 0 ? bm.bmWidth : dx; dy = dy == 0 ? bm.bmHeight : dy; Just to give you an idea of where this is in the code. There are no compiler errors, however when I run the program it never shades the bitmap, its probally something stupid so please help me: (btw if it is something stupid you can make fun of me) for(int y = 0; y >= bm.bmHeight; y++) { for(int x = 0; x >= bm.bmWidth; x++) { if(GetPixel(hdcImage,x,y) == (COLORREF)RGB(255,0,255)) { SetPixel(hdcImage, x, y, RGB(r, g, b)); } else if(GetPixel(hdcImage,x,y) == RGB(200,0,200)) { SetPixel(hdcImage, x, y, RGB(r - 40, g - 40, b - 40)); } else if(GetPixel(hdcImage,x,y) == RGB(255,100,255)) { SetPixel(hdcImage, x, y, RGB(r + 60, g + 60, b + 60)); } } } The GetPixel() doesnt seem to work, I tried putting message boxes inside the if() if they were to be set off, but they never came up.

When posting code on these forums use the and [ / s o u r c e ] tags (minus all those spaces) to insert a code box. Sorry I can''t help you with your problem <img src="sad.gif" width=15 height=15 align=middle>.
