    Question MFC Dialog :: Slider Control child notification messages?

    Hello, everyone. I have an MP3 file player application that I have been working on for quite a while. It uses the FMOD library, and MFC. I have MS Visual C++ 6.0 on a Windows 98 machine.

    Anyhow, it is coming along really well. I have the option to select a new directory (SHBrowseForFolder) for the "playlist" of files. I implemented a slider a few days ago, which displays the status of the track's time as it plays, which is no problem. BTW, this is an MFC Dialog-Based Application.

    With the slider, I would like the user to be able to drag the slider to select a new position in the song. The problem is, I don't know how to know when the slider's position has changed. Can anyone please tell me how to know when the user drags the tracker on a slider control? If so, I would really appreciate the help.

    Thanks for the help,
    Matt U.

    look at

    OnNMCustomdraw or NM_CUSTOMDRAW

    then get the slider pos and process.

    Talking Thanks for the reply ...

    Thanks for the reply. I figured it out myself. I just had to handle "OnHScroll" for a horizontal slider, and "OnVScroll" for a vertical slider. I just use the "TB_(Message)" messages for getting the new position.
