If you are using MFC, I recommend you go here:

for an excellent dialog box for picking directories.

>>Basically i need to locate where the cd drive is , that is the path.

If all you need is locating the CD drive, use this:

    DWORD   dwDrives;
    UINT    uDriveType;
    char    cDrive;
    char    acDriveName [   _MAX_DRIVE];

        for (   cDrive  =   0;  cDrive  <   26; cDrive++)
            {
                wsprintf    (   acDriveName,    "%c:\\",      cDrive      +      'A');

                uDriveType  =   GetDriveType(   acDriveName);
               
                if  (   DRIVE_CDROM ==  uDriveType)
                    {
                        // now acDriveName containes the drive letter of your CDROM...
                    }
            }

No, DRIVE_CDROM is #define'd in 'winbase.h'

Well, 'winbase.h' is usually being included by 'windows.h' anyway, so you shouldn't have to do that manually...
