    Question Transparent .gif, flickering.

    I have a control with a transparent .gif in a imagecontrol.
    Behind it there are moving lines.

    When the lines move fast and at a high framerate, the .gif "window" flickers, showing the color set as transparent.

    How can I stop this?

    LockWindowUpdate API might do.

    Or load the gif manually, and draw the display manually using a backbuffer. Definate flicker-free results!

    That API doesn't do it.

    How do I control this backbuffer in VB6?
    I am using a standard VB6 imagecontrol.
