Thread: cannot convert from HBITMAP__* to unsigned long

Code:

HBITMAP Ball = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_BALL));
			HBITMAP BallMask = CreateBitmapMask(Ball, RGB(255,0,255));

Code:

HBITMAP CreateBitmapMask(COLORREF hbmColour, COLORREF crTransparent);

HBITMAP CreateBitmapMask(HBITMAP hbmColour, COLORREF crTransparent)
{
	HDC hdcMem, hdcMem2;
	HBITMAP hbmMask;
	BITMAP bm;

	GetObject(hbmColour, sizeof(BITMAP), &bm); //bm holds ship info now
	hbmMask = CreateBitmap(bm.bmWidth, bm.bmHeight, 1, 1, NULL); //create a bitmap with same size

	hdcMem = CreateCompatibleDC(0); //two new DCs
	hdcMem2 = CreateCompatibleDC(0);

	SelectObject(hdcMem, hbmColour); //ship into MemDC
	SelectObject(hdcMem2, hbmMask);  //blank bitmap, same size, into MemDC #2

	SetBkColor(hdcMem, crTransparent); //background of DC with ship is pink

	BitBlt(hdcMem2, 0, 0, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);
	//ship with pink background blitted onto blank bitmap

	BitBlt(hdcMem, 0, 0, bm.bmWidth, bm.bmHeight, hdcMem2, 0, 0, SRCINVERT);
	//hDCMem2 has small bitmap w/ pink background

	DeleteDC(hdcMem);
	DeleteDC(hdcMem2);

	return hbmMask;
}

c:\documents and settings\administrator\desktop\leegames\pong\main. cpp(36) : error C2664: 'CreateBitmapMask' : cannot convert parameter 1 from 'struct HBITMAP__ *' to 'unsigned long'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast

i get that error when trying to make the bitmap mask

anyone know why?

LOL!

After reading my own post I saw the answer!

excuse me for such a stupid post.....
