[2005] Map Network Drives

[campster]

I need to map a network drive via code and found that .Net cannot do this directly so I tied to use API calls. Below is a start. The problem is that none of the errors are defined. To find the one that is shown, I forced an error then stepped through the code. There has to be a better way.

Private Sub MapDrive(ByVal strDrive As String, ByVal strPath As String)
 
        Dim err As Long
        Dim ERROR_ALREADY_ASSIGNED As Long = 8192874795449188437
 
 
        err = WNetAddConnection(strPath, "", strDrive)
 
        Select Case (err)
            Case ERROR_ALREADY_ASSIGNED
                WNetCancelConnection(strDrive, CType(True, Integer))
                WNetAddConnection(strPath, "", strDrive)
 
        End Select
 
    End Sub

I figured that the mapped drive was simply a key in the registry and I was correct (sort of). I can do this and create a key in the registry.

Private Sub MapDrive(ByVal strDrive As String, ByVal strPath As String)
 
        Dim regKey As RegistryKey = _
            Registry.CurrentUser.CreateSubKey("Network\" & strDrive)
        If Not (regKey Is Nothing) Then
            regKey.SetValue("ConnectionType", 1)
            regKey.SetValue("DeferFlags", 4)
            regKey.SetValue("ProviderName", "Microsoft Windows Network")
            regKey.SetValue("ProviderType", 131072)
            regKey.SetValue("RemotePath", strPath)
            regKey.SetValue("UserName", 0)
        End If
 
    End Sub

This makes a correct entry into the registry and the newly mapped drive appears in both the "Map Network Drive" and "Disconnect Network Drive" dialogs but it does not appear in "My Computer". I like this method because it modifies the registry even if the drive already exists. Can someone shed some light on what I'm missing with the registry approach?

I just found that if I create the registry key then restart my PC the drive is properly mapped. There must be a service that gets started/restarted when a drive is mapped using the API.
