How tp pass discrete value from VB6 to CR ?

I am using VB 6 and Crystal Reports 9. How can I pass a discrete value to
Crystal report ? What references should I include ? Thanks.

What do you mean by a 'discrete' value?

You can use the parameters collection.

VB Code:

'Add first parameter
oReport.ParameterFields.Item(1).ClearCurrentValueAndRange
oReport.ParameterFields.Item(1).AddCurrentValue dStartDate
'Add second parameter
oReport.ParameterFields.Item(2).ClearCurrentValueAndRange
oReport.ParameterFields.Item(2).AddCurrentValue dEndDate
