Vb.Net - How do you clear crystal reports parameters

Question

Hi,

I have an application that uses Crystal Reports. If I run a report e.g. Report A, works fine. Then I try running a different report e.g. Report B that has more parameters than Report A, I get an error message "The parameter is incorrect". I then try running Report A and get the same error message. To run a different report I have to come out of the application and then go back in.

The question is, How do I clear the previous crystal report to run another?

What syntax should I use e.g Close.

Any ideas?

Hi,

Try this if could help.

Right click the body of your Crystal Report
then goto:

Design -> Default Settings.. ->Reporting

Check the checkbox

Discard Saved Data When Loading Reports.

Click Ok then Save the report.

Please remember to mark the replies as answers if they help and unmark them if they provide no help.

Thanks for all your solutions.

I was missing one wee bit of code once the report was finished.

parameterfields.Clear()

Adding this line cleared the parameters.
