mciSendString

Could anyone help me with this problem? I can't get it to run with VS C++ 6.0... Thanx

Code:

#include <iostream> 
#include <windows.h> 
#include <mmsystem.h>
using namespace std;

int main() 
{ 
mciSendString("set cdaudio door open",NULL,0,NULL); 
Sleep(5000); 
mciSendString("set cdaudio door closed",NULL,0,NULL); 
return 0; 
}

What do you mean?...cant get it to compile??

If so add winmm.lib

Thanx! It compiled as soon as I added the winmm.lib.

Persoanlly I dont use this to open the CDROM.......you find that if you have 2 drives (as I do - 1 CDRW, 1 DVD), then you might want control over one of them.

If you have WinNT or above, you can use CreateFile to open a handle the drive (as a device - not just a disk). Then you can control each device seperately

For instance I have E drive and D Drive as CDROMs

Code:

#include <windows.h>
#include <winioctl.h>


int main()
{
	HANDLE hD = 0,
		hE = 0;
	enum DRIVE_{D_DRIVE = 0,E_DRIVE} e_drive = D_DRIVE;
	DWORD dwDummy;

	hD = CreateFile("\\\\.\\D:",GENERIC_READ,0,0,OPEN_EXISTING,
		FILE_ATTRIBUTE_READONLY,0);
	hE = CreateFile("\\\\.\\E:",GENERIC_READ,0,0,OPEN_EXISTING,
		FILE_ATTRIBUTE_READONLY,0);

	if(hD != INVALID_HANDLE_VALUE && hE != INVALID_HANDLE_VALUE)
	{
		for(int i = 0;i < 6;++i)
		{
			DeviceIoControl((e_drive ? hE : hD),
				IOCTL_STORAGE_EJECT_MEDIA ,0,0,0,0,&dwDummy,0);
			Sleep(3000);
			DeviceIoControl((e_drive ? hE : hD),
				IOCTL_STORAGE_LOAD_MEDIA,0,0,0,0,&dwDummy,0);
			Sleep(3000);
			e_drive = (e_drive ? D_DRIVE : E_DRIVE);
		}
	}

	if(hD)CloseHandle(hD);
	if(hE)CloseHandle(hE);
	return 0;
}

Sounds like little too complicated for me as of right now... but i'll save your code and see how far i can get with it. Actually i will have only one cd/rw on the system, and it is will be either Win NT 4.0 (presently) or Win XP (in the near future).
I already posted another thread with my next question that i have stuck with:

Check for a blank cd-r

Thanks, I'm learning a lot though all these posts.
