    Question Reading a TrackBar's position.

    I have this Trackbar with the handle of 'hTrackVolume' and with a control ID of 104. I have set up all of it's parameters. But it's useless if I don't know how to detect it's position. How do I do that?

    Thanks in advance, August.

    You can't using standard C/C++. You can using whatever OS platform you use as a target for your project. This site offers boards specializing in C#, Windows and Linux OS. Posting on the board appropriate for your target is the best idea I can give you at the moment.

    You can literally find this in a matter of seconds on MSDN. Anyway, you'll want to use the message TBM_GETPOS

    Something like:
    Code:
    DWORD dwPos;
    dwPos = SendDlgItemMessage(hDlg, IDC_SLIDER1, TBM_GETPOS, 0, 0);

    You've been here long enough, Cool-August, to know not to cross-post(see 4.):

    It's also a windows specific question.
