Hi i'm really new to c++ (i can only do basic stuff so far) but i was wondering if there was somehow a way to make a program open your cd tray???

The program is actually quite simple once you understand the code. Try this..

#include

void __fastcall Open()
{
DWORD bytes;
HANDLE hDevice = CreateFile("\\\\.\\D:", GENERIC_READ, FILE_SHARE_READ ,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_READONLY, NULL);
DeviceIoControl(hDevice,IOCTL_DISK_EJECT_MEDIA,NULL,0, NULL, 0, &bytes,
(LPOVERLAPPED) NULL);
CloseHandle(hDevice);
}

void __fastcall Close()
{
DWORD bytes;
HANDLE hDevice = CreateFile("\\\\.\\D:", GENERIC_READ, FILE_SHARE_READ ,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_READONLY, NULL);
DeviceIoControl(hDevice,IOCTL_DISK_LOAD_MEDIA,NULL,0, NULL, 0, &bytes,
(LPOVERLAPPED) NULL);
CloseHandle(hDevice);
}

Euh, not every CD Drive is Drive D.

Yeah, if you wanted to open a CD, you need to decide to get the drive letter by:

a) A registry value, saved after you query the user as to the CD drive they prefer
-or-
b) Enumerate the drives and check each drive's type (and then open ALL CDROM drives)
-or-
c) Same as b), but open only the first CDROM
-or-
d) Hardcode the letter (not recommended for a program you're distributing, but easiest for your own use).

If you're installing the program from a CD initially, it's easy to simply use the letter of the drive they installed from.

I think the best way to do it is enumerate the cd drives, and query the user if there is more than one drive.
