Obtaining the handle of CD drive

Hi,

I am using the following piece of code to obtain the handle to CD drive. This piece of code is working in WinXP and Win2k but its not able to get the handle in Win98.

HANDLE m_hDevice;
m_hDevice = CreateFile("\\\\?\\G:", GENERIC_READ, FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_READONLY, NULL);
if (m_hDevice==INVALID_HANDLE_VALUE)
{
AfxMessageBox("Cannot get handle");
}


Can someone help me ?

Regards
Gaurav

What happens when you remove/change the "FILE_SHARE_WRITE"

from MSDN

CreateFile
The CreateFile function creates or opens the following objects and returns a handle that can be used to access the object:

Consoles
Communications resources
Directories (open only)
Disk devices (Windows NT/2000 only)
^^^^^^^^^^^^^^^^^^^^^^^^^^
Files
Mailslots
Pipes

Thanks Dear. Do you know some other way to get the handle of CD drive in Win98.

What was the Error you are getting...

you can get it by using GetLastError()...
