discover if drive is CD-ROM, CD-R, DVD-Rom etc

[Guest]

Hi

Can someone please tell me how I can go about discovering whether a CD drive
is a ROM, R, RW or DVD-ROM, R, RW?

IMAPI is not possible for me because some of the PC's will be WindowsME
systems.

regards

Steve,

See this sample

Set a reference to System.Management.dll
Imports System.Management
..
..
..
Public Enum DriveType
Unknown = 0
NoRootDirectory = 1
RemoveableDisk = 2
LocalDisk = 3
NetworkDrive = 4
CompactDisk = 5
RamDisk = 6
End Enum

Public Function GetDriveType(ByVal strDrive As String) As DriveType
strDrive = "Win32_LogicalDisk='" & strDrive.Substring(0, 2) & "'"
Dim moDisk As ManagementObject = New ManagementObject(strDrive)
Return _
DirectCast( _
[Enum].Parse(GetType(DriveType),
moDisk("DriveType").ToString()), _
DriveType _
)
End Function
..
..
..
Dim astrDrives() As String = Environment.GetLogicalDrives()
Dim strDrive As String
For Each strDrive In astrDrives
MessageBox.Show( _
"Drive: " & strDrive & ControlChars.NewLine & _
"Type: " & GetDriveType(strDrive).ToString() _
)
Next strDrive
///
I hope this helps a little bit?

Hi Steve,

As far as I know, it's hard to detect if a CD Drive is a ROM, R, RW without
using IMAPI. In this case we have to use DeviceIoControl API to get these
information from the device driver directly. For more information about
this function, please check the following link.
