In my example I was populating a temporary file and my report didn’t have any parameters. If you want to know how to populate the parameters, here’s how you do it:

crxReport.ParameterFields(1).SetCurrentValue("Houston Department")

In case you need it, use the following to get the type of parameter. It returns a number (here are the common ones—7=Number; 8=Currency; 9=Boolean; 10=Date; 11=Time; 12=String; 16=DateTime):

crxReport.ParameterFields(1).ValueType

To get the parameter prompt, use:
crxReport.ParameterFields(1).Prompt

And this is how you get the number (count) of parameters:
crxReport.ParameterFields.Count

>Per the example you posted to generate a crystal reports viewer with-in a screen useing the crviewer class, how do you pass parameters to the report thus preventing the user from being prompted for the parameters?
