View 2 RepliesI'm trying to read the table of contents from a CD and am having problems with the DeviceIOControl function. When I call it with a control code of IOCTL_CDROM_EJECT_MEDIA or IOCTL_CDROM_LOAD_MEDIA it works fine, and opens or closes the CD drawer. But when I call it with a code of IOCTL_CDROM_READ_TOC_EX it gives an error code of 6 (ERROR_INVALID_HANDLE). I'm using the same handle, so I can't see why it's complaining. It's possible that the input data that I'm giving it is wrong, but I don't think that it should give this particular error in that case.
