Mapping a network drive and checking for its existence in VBScript

问题


I need to map a network drive into a network path using VBScript. The network path is read directly from input. How should I map the network drive and how to check whether the entered network path already exists?

I created a subroutine to map drives...

    MapDrive "H:","\\server\share"

    Sub MapDrive(letter, uncpath)
         on error Resume Next
         dim drivetype, currentmapping

        dim objWMIService 
        dim colDisks, objDisk

        'Set wshnetwork = CreateObject("Wscript.Network")
        Set objWMIService = GetObject("winmgmts:" & _
             "{impersonationLevel=impersonate}!\\.\root\cimv2")
        Set colDisks = objWMIService.ExecQuery _
            ("Select * from Win32_LogicalDisk Where Name = """ & letter & """")
        For Each objDisk In colDisks        
             drivetype = objDisk.DriveType      
            currentmapping = objDisk.ProviderName
        Next    


        if (drivetype <> 4 and drivetype <> 0) then
            NotifyUser ucase(letter) & " cannot be mapped due to a physical device already reserving that drive letter" & vbcrlf & _
                        "This is most frequently caused by a thumbdrive or external disk.",5
            exit Function
        end if

        if (ucase(currentmapping) = ucase(uncpath)) then
            exit function
        end If

        if (drivemappings.Exists(uncpath)) then
            drivemappings.Add uncpath & "(" & letter & ")", letter
        else 
            drivemappings.Add uncpath, letter
        end if

        if (currentmapping <> "") then
                wshnetwork.RemoveNetworkDrive letter,,True
        end if

        wshnetwork.MapNetworkDrive letter, uncpath, true

        on Error goto 0
     End Sub

I leave it up to you do handle error checking etc. Alternatively if you prefer the net use route you could do something like..

dim wshShell
Set wshShell = CreateObject("WScript.Shell")
wshshell.run "cmd /c net use H: ""\\server\share""",1,True

You can take it a step further to automagically use the next available drive letter to map drives using an example The Scripting Guys created.

Set objDictionary = CreateObject("Scripting.Dictionary")

strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")

Set colDisks = objWMIService.ExecQuery("Select * from Win32_LogicalDisk")

For Each objDisk in colDisks
    objDictionary.Add objDisk.DeviceID, objDisk.DeviceID
Next

For i = 67 to 90
    strDrive = Chr(i) & ":"
    If objDictionary.Exists(strDrive) Then
    Else
        Wscript.Echo strDrive & " is the next available drive letter."
        Wscript.Quit
    End If
Next
Wscript.Echo "There are no available drive letters on this computer.”

I hope this is helpful.




回答2:


run the following command in you vbscript file:

net use [NetDrive:] [Network Path]

for example:

net use Z: \\Hadi\temp

The sample command will map \Hadi\temp to Z:

Also take a look at this VBScript file for mapping network drives.
