After some tinkering, I've figured out how to get a parameter passed from a VB.NET form to a Crystal Report:
Dim paramFields AsNew CrystalDecisions.Shared.ParameterFields()
Dim paramField AsNew CrystalDecisions.Shared.ParameterField()
Dim discreteVal AsNew CrystalDecisions.Shared.ParameterDiscreteValue()
paramField.ParameterFieldName = "MyDateRange"
discreteVal.Value = Common.MyDates
paramField.CurrentValues.Add(discreteVal)
paramFields.Add(paramField)
crvBalances.ParameterFieldInfo = paramFields
This works just fine when the report is first opened in the Crystal Report Viewer. If I open the report a second time, however, using a different parameter, the old data is still on the report, and when I click the Refresh button in the report viewer, up pops that Parameter dialog box. I set the option to discard any saved data when loading the report, but that didn't help at all. Is there a way to KEEP the parameter dialog box suppressed and be able to refresh the report?
I'm running Visual Studio 2008, and using the version of Crystal that comes with same. Any help anyone can provide would be greatly appreciated.
