    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.
