Hi Al,

Don't know if this will help; found it at MS site:

-----------------------------------------------------------------
DrawIconEx Function

The DrawIconEx function draws an icon or cursor into the specified device
context, performing the specified raster operations, and stretching or
compressing the icon or cursor as specified.

Syntax

BOOL DrawIconEx(      

    HDC hdc,
    int xLeft,
    int yTop,
    HICON hIcon,
    int cxWidth,
    int cyWidth,
    UINT istepIfAniCur,
    HBRUSH hbrFlickerFreeDraw,
    UINT diFlags
);

Parameters

    hdc
[in] Handle to the device context into which the icon or cursor will be
        drawn.
    xLeft
[in] Specifies the logical x-coordinate of the upper-left corner of the
        icon or cursor.
    yTop
[in] Specifies the logical y-coordinate of the upper-left corner of the
        icon or cursor.
    hIcon
[in] Handle to the icon or cursor to be drawn. This parameter can
        identify an animated cursor.
    cxWidth
[in] Specifies the logical width of the icon or cursor. If this
        parameter is zero and the diFlags parameter is DI_DEFAULTSIZE, the function uses
        the SM_CXICON or SM_CXCURSOR system metric value to set the width. If this
        parameter is zero and DI_DEFAULTSIZE is not used, the function uses the actual
        resource width.
    cyWidth
[in] Specifies the logical height of the icon or cursor. If this
        parameter is zero and the diFlags parameter is DI_DEFAULTSIZE, the function uses
        the SM_CYICON or SM_CYCURSOR system metric value to set the width. If this
        parameter is zero and DI_DEFAULTSIZE is not used, the function uses the actual
        resource height.
    istepIfAniCur
[in] Specifies the index of the frame to draw, if hIcon identifies an
        animated cursor. This parameter is ignored if hIcon does not identify an animated
        cursor.
    hbrFlickerFreeDraw
[in] Handle to a brush that the system uses for flicker-free drawing. If
        hbrFlickerFreeDraw is a valid brush handle, the system creates an offscreen
        bitmap using the specified brush for the background color, draws the icon or
        cursor into the bitmap, and then copies the bitmap into the device context
        identified by hdc. If hbrFlickerFreeDraw is NULL, the system draws the icon or
        cursor directly into the device context.
    diFlags
[in] Specifies the drawing flags. This parameter can be one of the
        following values:

        DI_COMPAT
Draws the icon or cursor using the system default image rather than
            the user-specified image. For more information, see About Cursors. Windows NT4.0
            and later: This flag is ignored.
        DI_DEFAULTSIZE
Draws the icon or cursor using the width and height specified by the
            system metric values for cursors or icons, if the cxWidth and cyWidth parameters
            are set to zero. If this flag is not specified and cxWidth and cyWidth are set to
            zero, the function uses the actual resource size.
        DI_IMAGE
            Draws the icon or cursor using the image.
        DI_MASK
            Draws the icon or cursor using the mask.
        DI_NOMIRROR
Windows XP: Draws the icon as an unmirrored icon. By default, the
            icon is drawn as a mirrored icon if hdc is mirrored.
        DI_NORMAL
            Combination of DI_IMAGE and DI_MASK.

Return Value

    If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error
    information, call GetLastError.


Remarks

The DrawIconEx function places the icon's upper-left corner at the location
    specified by the xLeft and yTop parameters. The location is subject to the
    current mapping mode of the device context.

    To duplicate DrawIcon (hDC, X, Y, hIcon), call DrawIconEx as follows:

DrawIconEx (hDC, X, Y, hIcon, 0, 0, 0, NULL, DI_NORMAL | DI_COMPAT |
DI_DEFAULTSIZE);
