    Hi Mike

    I think I've come up with a simply solution on how to create an icon with
    the shadow effect, but I need a little help please.

    I had a Picture Box control on to a Form and then used the SHGetFileInfo API
    to get a handle to the small icon with an Alpha Channel. I then used the
    DrawIconEx API to draw the icon on to the Picture Boxes DC. The icon is drawn
    with the shadow effect.

    This is what I'm thinking as a solution:
    - Use the SHGetFileInfo to get a handle to the small file icon
    - Create a DC using the CreateCompatibleDC API
    - Draw the icon on to the DC using the DrawIconEx API (so that the alpha
    channel is drawn as the shadow effect)
    - Use the GetIconInfo API to get the Icon info
    - Replace the icon bitmap with the image that was drawn in the DC. There is
    no need to change the mask
    - Convert the icon into a StdPicture object

    It the "Replace the icon bitmap with the image that was drawn in the DC" bit
    I don't know how to do.

    Can you please show me how to do that bit?

    Thanks again

    Regards
    Mark
