I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Here is code I found to add a dsn (user but should work for others as well)  the problem is that when it adds the Microsoft text driver dsn it sets use current directory flag instead of taking the path I pass to it.  what do I need to change to get this to work

Private Declare Function SQLConfigDataSource Lib "ODBCCP32.DLL" (ByVal _
    hwndParent As Long, ByVal fRequest As Long, ByVal lpszDriver As String, _
