The code below works fine if I rename the .dbf to something with equal or less then eight characters before the extension.
Unfortunately the dbf is created by another program and is updated a few times per hour, so renaming it all the time is the last on my list of options to fix this problem.
So I used the GetShortPathName function, but that introduced the next problem.
I think the tilde ~ causes a syntax error, but as I'm very new to .NET I don't know how to fix it. Hopefully it is something simple.

 
'get datetime
Dim Vandaag As DateTime = DateTime.Today
'extract the year
Dim jaar As String = Vandaag.ToString("yy")
'put the year in the filename
Dim bestandsnaam As String = "F:\ICONNECT\tracerap_" & jaar & ".DBF"
'shorten the filename
bestandsnaam = GetShortFileName(bestandsnaam)
'and grab the last 12 characters
bestandsnaam = bestandsnaam.Substring(bestandsnaam.Length - 12, 12)
'the result for this year is TR39C1~1.DBF
'set up the query
Dim ConnectionString As String
ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\Fileserver\DATA\ICONNECT;Extended Properties=dBase IV"
Dim dBaseConnection As New System.Data.OleDb.OleDbConnection(ConnectionString)
dBaseConnection.Open()
Dim QueryString As String = "SELECT * FROM " & bestandsnaam
'this line is where the syntax error is reported
Dim dBaseCommand As New System.Data.OleDb.OleDbCommand(QueryString, dBaseConnection)
Dim dBaseDataReader As System.Data.OleDb.OleDbDataReader = dBaseCommand.ExecuteReader(System.Data.CommandBehavior.CloseConnection)


Who can help me with this?
TIA for your time.

PS F:\\ and \\Fileserver\DATA\ point to the same location

Thank you very much. :)
Can you explain why this matters?
For the simple filenames it worked fine without the brackets.
