Map network drive

[fallnwrld]

How would i go about mapping \\lab_techs\c\ when my program starts up? If possible assign it to letter T but if you just know how to map that directory it would be a big help thanks.

The WNetAddConnection function works and is simple.

However it is now obsolete (16-bit) and you should use
WNetAddConnection2 which is a little more complexe.

Here's some code that works - just copypaste it into a form
with a command button 'cmdMapDrive' and change the strNetResName var:
'================================
Option Explicit

Public Type NETRESOURCE
dwScope As Long
dwType As Long
dwDisplayType As Long
dwUsage As Long
lpLocalName As String
lpRemoteName As String
lpComment As String
lpProvider As String
End Type
'--------------------
' some error values - there's loads of these so check 'em out
Const ERROR_INVALID_PASSWORDNAME = 1216&
Const ERROR_ACCESS_DENIED = 5&
Const ERROR_BAD_DEVICE = 1200&
Const ERROR_BAD_PROFILE = 1206&
Const ERROR_DEVICE_ALREADY_REMEMBERED = 1202&
Const ERROR_DEV_NOT_EXIST = 55&
Const ERROR_ALREADY_ASSIGNED = 85&
Const NO_ERROR = 0
'--------------------
Const RESOURCETYPE_DISK As Long = &H1& 'dwType
'--------------------
Private Declare Function WNetAddConnection2 Lib "mpr.dll" _
Alias "WNetAddConnection2A" (lpNetResource As NETRESOURCE, _
ByVal lpPassword As String, _
ByVal lpUserName As String, _
ByVal dwFlags As Long) As Long
' dwFlags
Const CONNECT_UPDATE_PROFILE As Long = &H1&
'--------------------
Dim netRes As NETRESOURCE
Dim lResult As Long

' connect to the network drive
Private Sub cmdMapDrive_Click()
Dim strDriveLetter, strNetResName As String
Dim strPswd, strUser As String

strDriveLetter = "T:" + Chr$(0)
strNetResName = "\\some_network_computer\some_dir" + Chr(0)

With netRes
.dwType = RESOURCETYPE_DISK
.lpLocalName = strDriveLetter
.lpRemoteName = strNetResName
.lpProvider = ""
End With
' don't need to fill in the other fields in most cases

lResult = WNetAddConnection2(netRes, _
strPswd, _
strUser, _
CONNECT_UPDATE_PROFILE) '// update profile with connect information

' check for errors using const's defined above
Select Case lResult
Case NO_ERROR
' no problem
'Case any other erros
'.
'.
'.
Case Else
'problem
End Select

End Sub
'===========================
You should put a lot of this in a module or maybe make a
class out for it and include adequate error checking and
parameters etc. for modularity.
