Hi, I'm using VS 2005, .net 2.0 and C#.  I developed my crystal report using the developer version, 11.0 and then add the report to my proejct.  In my project, I have a winform that has a CrystalReportViewer control on it.  I would like to use this form to produce report preview for all the reports in my project.  So, I would like to assign different reprotPath to the CrystalReportViewer control and also different dataset.  

For my first report, I created a dataset in my proejct, dsEventLog.xsd.  I created a table in this dataset in the designer with the columns.  I use the following code to run my report but the crystal report displays none of the data that I entered as rows in my code to this dataset's table.  What am I doing wrong here?  Thanks.




        private void btnOK_Click(object sender, EventArgs e)
        {
            dsEventLog dsLog = new dsEventLog();
            String padEventType = null;          
           
            // Associate the instance of 'EventLog' with local System Log.
            EventLog padEventLog = new EventLog("Directory Service", ".");

                padEventType = "Information";

            EventLogEntryCollection padLogEntryCollection = padEventLog.Entries;
            int logCount = padLogEntryCollection.Count;
            string user;
            // Iterate through all 'EventLogEntry' instances in 'EventLog'.
            for (int i = logCount - 1; i > 0; i--)
            {
                System.Diagnostics.EventLogEntry padLogEntry = padLogEntryCollection[i];
                // Select the entry having desired EventType.
                if (padLogEntry.EntryType.ToString().Equals(padEventType))
                {
                    DataRow dr = dsLog.Tables[0].NewRow();
                    dr["Date"] = padLogEntry.TimeGenerated.ToShortDateString();
                    dr["Time"] = padLogEntry.TimeGenerated.ToShortTimeString();
                    dr["Source"] = padLogEntry.Source.ToString();
                    dr["Category"] = padLogEntry.Category.ToString();
                    dr["Event"] = padLogEntry.InstanceId.ToString();
                    if (padLogEntry.UserName == null)
                        user = "N/A";
                    else
                        user = padLogEntry.UserName.ToString();
                    dr["User"] = user;
                    dr["Computer"] = padLogEntry.MachineName.ToString();
                    //string[] logItem =
                    //dr.ItemArray = new string[] { padLogEntry.TimeGenerated.ToShortDateString(),
                    //    padLogEntry.TimeGenerated.ToShortTimeString(), padLogEntry.Source.ToString(),
                    //    padLogEntry.Category.ToString(), padLogEntry.InstanceId.ToString(),
                    //    padLogEntry.UserName.ToString(), padLogEntry.MachineName.ToString()}; ;
                    dsLog.Tables[0].Rows.Add(dr);                
                }
            }
            int rows = dsLog.Tables[0].Rows.Count;
            ReportPreview logPreview = new ReportPreview();
            string reportPath = Application.StartupPath + "\\" + "EventLogReport.rpt";
            logPreview.crViewer.ReportSource= reportPath;

            logPreview.crViewer.Refresh();
            logPreview.crViewer.RefreshReport();

            if (ckbPreview.Checked == true)
            {
                logPreview.ShowDialog();
            }
            else
            {
                logPreview.crViewer.PrintReport();
            }
            //myDoc.Dispose();
            logPreview.Dispose();

            //All done, clean up
            dsLog.Tables.Clear();
            dsLog.Dispose();
            GC.Collect();
            Cursor = Cursors.Default;

        }

I think you should take alook at all your clean up code like logpreview.dispose(),dslog.tables.clear(),dslog.dispose can you try without these...

and one more question how are you assigning the datasource to .rpt file.

When I created the crystal report I selected the dsEventLog.xsd that I created in my C# proejct.  All the data field in my CR are from this dataset's table.  I don't thknk             dsLog.Tables.Clear();
            dsLog.Dispose();
would be the problem but I tried it as you suggested and it doesn't make any difference as I thought.  
 
Thanks.
