Why can't I set a connectionString?

[Dave Midgley]

I am writing a VB app (called FISWDC) with a data environment (called DataEnv). I believe I should be able to do: DataEnv.Connection.connectionString = "File Name=" & App.Path & "\FISWDC.UDL;" or, at least DataEnv.Connection.connectionString = "File Name=FISWDC.UDL;" or maybe DataEnv.Connection.Open "File Name=" & App.Path & "\FISWDC.UDL;" or something like that, but whatever I do I just keep getting the error "The parameter is incorrect" or "Connection was denied. New connection you requested has different characteristics than the one already in use." Can anyone help? Dave

Have you double-checked the UDL-files contents? Try using the UDL on a clean connection object: Dim cnn As New ADODB.Connection cnn.Open "File Name=c:\test\file.udl"
