    Sub(iStt As Integer)
    ' do job

    Dim temp As New Dummy(list(iStt), iStt, screen, P6, P4, tempFolder, pagesize, P7, P8, list.Count) '-- Create an instance of our dummy class with a string name.

    Sorry to mention that AR7 was declared a legacy product now. It is out of maintenance mode now. Hence, we do not provide support for the same or no bug fixing will be done in the same. I would recommend you use the latest version of ActiveReports i.e ActiveReports 13. Please refer to the following link for more information:

    It is very helpful for us if you provide a stripped-down sample so that I can look into this.
