In my web app, my report has the same data everytime I access it. I DO NOT have the Save Data with Report checked.  The only data that comes up is the data that gets displayed in design time.

I am updating my parameters but when i trace the stored procedure calls the parameters are not updated.

The data doesn't update whether I use crystal viewer or generate the report in pdf.

I am using crystal 9 advanced, Windows 2003, SQL Server. I have been at this for sometime now and cannot get it figured out!

Any help would be great.

Thanks, Jordan

It looks like you're getting the parameter values from a cookie.  Have you verified that the values in your code are changing correctly?  I'm thinking there could be a caching problem in your browser that may be sending the old params?

Well, some weird stuff is going on.

I was opening my reports in a new browswer, which I do on my production server currently and everything is great.

I set up a new server with Windows 2003 and things are acting up now.

I changed my reports to not spawn a new window and I also just now added:

crReportDocument.Refresh();

This has made my reports work just great. However, when I return to spawning the reports in a new window the cookies are not being found. I don't understand at all what is causing that.  It works fine.  I am wondering if it has something to do with 2003 and IIS6?

THanks,
Jordan

I think the problem is not with the execution of Crystal Rpt. Its due to some default options set during designing of Crystal Rpt.

If you used ADO/RDO/DAO to design a report, you need to paste a SQL qry during design time.
While executing this query thro Crystal report to bring "Data Fields" in to the report, Cr-Rpt Designer connects to DB and executes the SQL that you used during design time. That SQL may return a set of data, and that data will always be displayed in the Report during runtime. (I THINK THIS IS THE PROBLEM YOU ARE FACING)

* To rectify it open the report in Open the Rpt in "32 bit Crystal Report Designer".
* Verify the option in "File Menu>>> Save Data with Report".
   By default this is in checked state.
   Uncheck this option and execute as you did before.


This will solve the issue.
