Thread: Draw a semi-transparent icon in winapi.

People.
How can I draw a semi transparent icon in winapi with WM_PAINT ?
I mean i'm using functions like

Code:

HICON hIconPic =  LoadImage(_hInstance, MAKEINTRESOURCE(IDI_ICON), IMAGE_ICON, 320, 240, LR_LOADTRANSPARENT);
HDC dcIconPic = CreateCompatibleDC(0);
HICON hSecondIcon = (HICON)SelectObject(dcIconPic, hIconPic);
DrawIconEx(ps.hdc, 0, 0, hIconPic, 0, 0, 0, NULL, DI_NORMAL );

to draw an Icon in winapi window, but the transparency of the icon image is only fully transparent.
Semi-transparency doesn't work ! The semi transparency shown as white color. Can it be implemented somehow easily?

I don't think so. The icon alpha channel isn't natively supported in XP and below. You'll have to make your own function for that, or install a library or graphics engine of some kind.
