I get the error message indicated in the title each time I log off the computer after the application is closed.

The .net application uses a crystal reports active-x.

How do i get rid of this error?

Can you change the application?

How is the application calling the reports?

Any idea what version of Crystal?

How do you close the report viewer?

How do you assign the report file to the viewer?

I was hoping this forum would tell me how to close the reportviewer. THe report file code is already attached -- crv.ReportSource = rptSecur03;.

I used the folowing code on form_closing to clear the com object from memory

private void clearReportsFromMemory(CrystalDecisions.CrystalReports.Engine.ReportDocument rpt)
        {
            try
            {
                if(rpt != null)
                {
                    if (rpt.IsLoaded)
                    {
                        rpt.Database.Dispose();
                        rpt.Close();
                        rpt.Dispose();
                        GC.collect

                    }
                }
                   
             
            }
