Crystal Reports - Always saving data
Greetings,
My Crystal Report saves data and then on the next run, the data doubles. Below is my code:
Try
With crConnectionInfo
.DatabaseName = dbase
.UserID = ""
.Password = ""
End With
CrTables = cryRpt.Database.Tables
For Each CrTable In CrTables
crtableLogoninfo = CrTable.LogOnInfo
crtableLogoninfo.Connectio
CrTable.ApplyLogOnInfo(crt
Next
cryRpt.SetDatabaseLogon(""
crViewerStats.ReportSource
cryRpt.Refresh()
crViewerStats.Refresh()
crViewerStats.PrintReport(
Catch ex As Exception
MessageBox.Show("Problem printing reports: " & ex.Message, "", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
I refresh the report and viewer, but the report adds the new data to the previous data. It's obviously storing the data in the report.
Thanks
VW

Yes, I have the Save Data with Report unchecked . This is what makes no sense. With the Save data report unchecked, why would the data be reused. I checked the database to be sure that the data was not being doubled, but but it is being erased and then rewritten.
The cryRpt.DiscardSavedData command gives me the cannot resolve symbol error. ??

Try using only 1 refresh or remove both refreshes.
If there is no saved data then there is no need to refresh.

The problem has taken another turn. The process dumps exam scores to the database and then the CR generates standard stats (mean, median, mode, sd, reliability, etc. mimcc (above response) got me to thinking about the saved data. My first stat is a count of the records.
Count ({ExamGrades.Score})
This field keeps incrementing, but the other stats are being computed correctly. So, why would the count not correctly indicate the correct number or records?
Actually, I guess this may be a second question.

Does the process clear the database/table before adding records?

Yes, I delete all the records before I write to the table. When the report is stating that there are 400 records, i can pull up the database and only have 148
What SQL is the report running when it shows 400?

If you refresh the report does it show the correct amount?

I am using a Select All query. I had the refresh reports in, but will try putting them in again. The really strange part is if I run the report; open the database and manually adjust some of the scores, and then refresh the report, the stats are correctly changed, but the number of records is still incorrect.
One other point. I originally create the report in the IDE, but have occassionally used Crystal Reports 2008 to view the report and sometimes make minor changes to the formatting. Could this be a problem?
Thanks for your input and time.

How are you getting the number of records?
The editting in CR2008 is possibly the issue but CR4VS2010 was supposed to be CR v13 which I would think included all of CR2008 (v12)

I am using the CR Count{} funtion.
Can you upload the report?

The report and db did not upload. Will do it again tonight.

I don't see anything in the report that would cause the issue.
what code do you use to update the data?

I use oledb. I use a delete all before the insert into. After the insert there are only 148 records. How the count function returns there increasing number, is strange. Could the fact that the functions are in the header cause a problem?

I delete with code. I will modify to see the records. I delete the records and then open the report.
ASKER
I display the records in the report and there are approx 1200. ) It keeps incrementing each time.) While the report is being displayed, I open the database and there are 89 records.

Now for the strange part. If I print the scores in the detail section of the report and place the data in the Report Footer, everything prints correctly. I guess I will stay with this. I appreciate the input and time from mimcc and am going to award the points
Thanks again
Thanks again
If so turn it off
Try using this line before the refresh
cryRpt.DiscardSavedData
