Ejecting CD-ROM

[imagenetics]

There is a combo-box in my program listing all available CD-ROM drives, by their letters (D:\, E:\, F:\, ...). I wish to add a button which will eject the selected drive. I know there is a mciSendString() to do this but no matter which drive I select in the combo, my audio drive is ejected every time. Is there a way to eject certain CD-ROM drive based on its letter?

You might want to look at the TMediaPlayer. It encapsulates the mciSendString() and will allow you to select which drive to eject.

Do you mind elaborating on that? What should I do? I'll appreciate a code example. Thanks.

You can create a new media player or drop the component on your form. The your code might look something like this:

MediaPlayer1->DeviceType = dtCDAudio; // I think this must be set to something
// Look at the help for the different devices.
MediaPlayer1->FileName = "D:"; // For example, maybe D:\*.*
MediaPlayer1->Open();
MediaPlayer1->Eject();
MediaPlayer1->Close();

I'm going from memory here, so watch out!

That doesn't seem to work exactly as I expect, but thanks anyway.
