Using a datareader multiple times

Can you use a datareader multiple times?

Close() it, reopen it, and Read() it again!

I tried that and it still fails. I must be having a different problem then.

Thanks.

Maybe you have to reassign it with the ExecuteReader() method, because it is a forward-only IO object.

This is some sample code of how I might do it:

VB Code:

MyODBCConn = New Microsoft.Data.Odbc.OdbcConnection(myConnectionString)
 
 
        For MyI = 0 To UBound(mPrinters)
            MyFiles = System.IO.Directory.GetFiles(LogDir & mPrinters(MyI).pName & "\temp\", mPrinters(MyI).pLogNameHint & "*")
            For MyJ = 0 To 0 'UBound(MyFiles)
                strSQL = "SELECT DISTINCT cms.print_history_log.log_file_name FROM cms.print_history_log WHERE cms.print_history_log.log_file_name = '" & mPrinters(MyI).pName & "\" & System.IO.Path.GetFileName(MyFiles(MyJ)) & "' "
                MyODBCConn.Open()
                MyODBCCommand = New Microsoft.Data.Odbc.OdbcCommand(strSQL, MyODBCConn)
                MyODBCReader = MyODBCCommand.ExecuteReader(CommandBehavior.CloseConnection)
                'MsgBox(MyODBCReader.GetName(0).ToString)
                If MyODBCReader.Read = True Then
                    'move file to main
                    MyMovePath = LogDir & mPrinters(MyI).pName & "\" & System.IO.Path.GetFileName(MyFiles(MyJ))
                    System.IO.File.Move(MyFiles(MyI), MyMovePath)
                End If
                MyODBCReader.Close()
                MyODBCCommand.Dispose()
                MyODBCConn.Close()
                Me.Text = MyI & "_" & UBound(mPrinters) & " " & MyJ & "_" & UBound(MyFiles)
                Application.DoEvents()
            Next
        Next
        MyODBCConn.Close()
        MyODBCConn.Dispose()
