[2005] DRIVE MAPPING PAssing the User ID. (using WNETAddConnection Function )

Hello community,

Im connecting to a mapped drive via a smal app im trying to write.
Im using the WNETAddConnection Function but i noticed it only takes 3 parameters.

I need to pass it my user ID since the Authentication on the server im connectiong to uses a different USer ID for me instead of my systems ID.

Is there a parameter im missing or am i using the correct function??

Code:

---

Private Declare Function WNetAddConnection Lib "mpr.dll" Alias "WNetAddConnectionA" (ByVal lpszNetPath As String, ByVal lpszPassword As String, ByVal lpszLocalName As String) As Long)

---

Look at the wnetaddconnection2 function

http://msdn2.microsoft.com/en-us/library/aa385413.aspx

OK thanks , i see the description so now im building the app but i have another question

I see the new Methods for WNET..2 , the first parm LpNetResource is a structure.

DO i have to populate all of the entrys within that structure or can i just populate the path and letter?

Code:

    Public Const ForceDisconnect As Integer = 1
    Public Const RESOURCETYPE_DISK As Long = &H1

Public Structure NETRESOURCE
        Public dwScope As Integer
        Public dwType As Integer
        Public dwDisplayType As Integer
        Public dwUsage As Integer
        Public lpLocalName As String
        Public lpRemoteName As String
        Public lpComment As String
        Public lpProvider As String
    End Structure


Dim nr As NETRESOURCE

 nr = New NETRESOURCE
        nr.lpRemoteName = UNCPath
        nr.lpLocalName = DriveLetter & ":"
        strUsername = Nothing '(add parameters to pass this if necessary)
        strPassword = Nothing '(add parameters to pass this if necessary)
        nr.dwType = RESOURCETYPE_DISK

 Try
            result = WNetAddConnection2(nr, strPassword, strUsername, 0)
        Catch ex As Exception
            MessageBox.Show("Error in MapDrive: " & vbCrLf & ex.Message.ToString)
        End Try

This is my code, I have looked over it and found no eerors form what everyone has helped with.

My environment is a XPpro system connecting to a Oracle server(unsure of OS nx or ms).

I get no error and my message box returns false as it should since i have not connected. I triple verified my pw and id's to make sure they were correct by watching the values as the app debuged.
any advice would be welcome.

You should note that if a system is already has a mapped drive using user A credentials, you can not map another drive using different credentials... You should try this manually and you'll see what I'm taking about.

OK,

Ill explain my setup. Currently my org is logged into a domain under the following format.

Username[at]sub3.sub2.sub1
and all of our drives our mapped under this context.


the drive i'm trying to reach is :
Username[at]sub2.sub1

I can in fact connect to this drive manualy by typing in the information and User and PW info but when i try to use WNET..2 it fails and also fails with WNET..

The domain is under Novell if im not mistaken, might this have an issue to do with it?

Try to map a drive using NET USE command from command prompt. If you succeed, simply write a function to map your drive using a process to start net use....
