    Question Slider not incrementing with the video.?


    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.

    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.

    However, this thread may be of interest
    All advice is offered in good faith only. All my code is tested (unless stated explicitly otherwise) with the latest version of Microsoft Visual Studio (using the supported features of the latest standard) and is offered as examples only - not as production quality.
