This can be easily done by using map network drive in Network Neighbourhood or My Computer but it can be useful to be able to do this in Visual Basic.  I will now show you how to do this using Windows API.  Here is the example: Also includes how to delete a connection. Start a new Standard-EXE project, form1 is created by default Add a standard module and add a command button to form1 Type the following in the standard module. Option Explicit Declare Function WNetAddConnection Lib "mpr.dll" Alias _ "WNetAddConnectionA" (ByVal lpszNetPath As String, _ ByVal lpszPassword As String, ByVal lpszLocalName _ As String) As Long Declare Function WNetCancelConnection Lib "mpr.dll" _ Alias "WNetCancelConnectionA" (ByVal lpszName _ As String, ByVal bForce As Long) As Long Const WN_SUCCESS = 0 ' The function was successful. Const WN_NET_ERROR = 2 ' An error occurred on the network. Const WN_BAD_PASSWORD = 6 ' The password was invalid. Function AddConnection(MyShareName As String, _ MyPWD As String, UseLetter As String) As Integer On Local Error GoTo AddConnection1_Err AddConnection = WNetAddConnection(MyShareName, _ MyPWD, UseLetter) AddConnection_End: Exit Function AddConnection_Err: AddConnection = Err MsgBox Error$ Resume AddConnection_End End Function Function CancelConnection(DriveLetter As String, _ Force As Integer) As Integer On Local Error GoTo CancelConnection_Err CancelConnection = WNetCancelConnection(DriveLetter, _ Force) CancelConnection_End: Exit Function CancelConnection_Err: CancelConnection = Err MsgBox Error$ Resume CancelConnection_End End Function to add a connection call by: varible = AddConnection(<SharePath>, <Password>, <DriveLetter>) To cancel a connection type: varible = CancelConnection(<SharePath, <Force>) Run the project.
