{RESOLVED} Creating Virtual Drives

[corydg]

I installed a program that created virtual drives. It created two drives that simply are alias' to my C drive. They aren't network drives which is why i'm baffled.

If anyone has a way to create and remove them, please tell.

I have Daemon Tools, which lets me use IMG files as a virtual drive, so that I don't have to burn a CD in order to install something.

I noticed that each of the drives point to a specfic like G point to C:\Spots and R point to C:\Cuts.

They are masked to look like their own drives, but they aren't. the capacity of them is the same as my C drive and the amount used is the same also.

They work just like normal hard drives, but they're not physical drives.

Same here. My F: drive reports in as a DVD player, the same size as my C: drive

Is there a way to create this in VB? They used C++ to do this.

Sure:

Private Declare Sub Sleep Lib "kernel32.dll" ( _
    ByVal dwMilliseconds As Long _
)
 
Public Function MapVirtualDrive(sDriveLetter As String, sPath As String) As Boolean
    'This function will try to map a virtual drive (sDriveLetter) to a physical path (sPath)
    'Returns True on success
    If Len(sDriveLetter)
        sDriveLetter = Left$(sDriveLetter, 1) & ":"
        If Len(Dir$(sPath, vbDirectory)) > 0 And Len(Dir$(sDriveLetter & "\", vbDirectory)) = 0 Then
            Shell "subst " & sDriveLetter & " " & sPath, vbHide
            Call Sleep(500)
            MapVirtualDrive = (Len(Dir$(sDriveLetter & "\", vbDirectory)) > 0)
        End If
    End If
End Function

that's a lot less code than i though i'd need,

Thanks,

How Do You Un-Map or Kill a virtual drive?

[Joacim Andersson]

Public Function UnmapVirtualDrive(ByVal sDriveLetter As String) As Boolean
    If Len(sDriveLetter) Then
        sDriveLetter = Left$(sDriveLetter) & ":"
        If Len(Dir$(sDriveLetter & "\", vbDirectory)) Then
            Shell "subst " & sDriveLetter & " /D", vbHide
            Call Sleep(500)
            UnmapVirtualDrive = (Len(Dir$(sDriveLetter & "\", vbDirectory)) = 0)
        End If
    End If
End Function
