This thread is for discussions of Virtual Drive.

It really works!
And fast too!!

Be very careful using the SUBST command on WinNT/2000/XP, it is dangerous.  NTFS permissions can conflict with each other say drive F: is actually a drive created from a subdir of Drive C:, applying NTFS permissions to drive C: that conflict with drive F: can cause NTFS corruption.  You may find yourself logged in as Admin and no longer able to access files or whole directories due to the corruption.  Microsoft has acknowledged this and suggests against the usgae of SUBST on WinNT based machines.  Win9x/ME does not have this issue due to lack of NTFS.

But here's a much cleaner method...



Option Explicit

Private Const DDD_REMOVE_DEFINITION As Long = &H2

Private Declare Function DefineDosDevice Lib "kernel32" Alias "DefineDosDeviceA" (ByVal dwFlags As Long, ByVal lpDeviceName As String, Optional ByVal lpTargetPath As String = vbNullString) As Long


Public Function Subst(ByVal Drive As String, ByVal Path As String) As Boolean
  Subst = CBool(DefineDosDevice(0, Drive, Path))
End Function

Public Function UnSubst(ByVal Drive As String) As Boolean
  UnSubst = CBool(DefineDosDevice(DDD_REMOVE_DEFINITION, Drive))
End Function



...and an example...


If Not Subst("P:", "C:\My Documents\Shameless Porn") Then MsgBox Err.LastDLLError

...and, subsequently....

If Not UnSubst("P:") Then MsgBox Err.LastDLLError


... Groovy, no?

OK..nice code.. but how about this..can anybody help e to solve this problems.

-->i'm planning to create the virtual drive in windows 2000 and map some webserver folder or ftp folders to that  
    drive and allow client to work as his physical drive..
--> pls Help me as soon as possible

I have XP with my primary drive NTFS but I intend to use this program for an external FAT32 drive. Will I still risk NTFS corruption, or am I safe with the FAT32?

Sorry for being a bit of a thick. Please can tell me how you got the code to work. I'm using VB 2005 express edition, and have managed to build and execute the code. But all I get is a virtual hard drive. I don't see how the code in the module gets called. Its the same as if I  use subst from the command line.
