    Question Slider not incrementing with the video.?

    Hi,

    I am using DirectShow to play/pause/stop a video file. I am having a slider control which increments with the playing video. I have done some calculation to find the exact step to forward or backward the video.
    On dragging the slider to any position, video forwards/backwards to the new position, but slider doesn't get increment. Say I drag the slider from 10 to 50, video goes to the new position, but on releasing the capture slider again jumps back to the previous position from where it was dragged.

    Any idea of where is the problem with this issue.?

    Need some help regarding this.

    Regards,
    Mbatra

    How do you handle slider notifications (TB_THUMBTRACK, TB_THUMBPOSITION, TB_ENDTRACK)?

    As you haven't posted your code we can't really say what is the problem.
