Passing a parameter to ReportPro 2.30a

[Anonymous]

Hi again. I'm sure that many many moons ago, I was able to make ReportPro pop up a dialog asking for a parameter such as a date from/date to. Sure, I can do it from within VO no problem at all, but I'm sure you can do it using ReportPro also, I cannot for the life of me find it anywhere in sample RP files, or the RP help. I used to use RP 2.17 maybe it was a feature in earlier versions, but not 2.30a?

Anyway, my memory is usually pretty good with things like that.. Is my memory correct? If so, how do you do it please. All I want to achieve is have the user put either Y/N and based on the response print or not print a particular field. As I say, I can do it from within VO, but once I start on something, I don't like it beating me...

Thanks in advance..... again!

Jeff,
There is a method ExpressionBuilder on the RpReport class to bring up an expression builder.
You can use the result of this expression builder this for the Seek expression, While expression, Filter Expression and also for the Variable Init expressions and Variable Update Expressions.

As far as I know there has never been a dialog to enter parameters or variables.
There is a SetVariableValue method that allows you to set the value of a variable at runtime.

Whilst on ReportPro - something that came up today trying to export a report >100 pages to PDF:

The following error was encountered while fetching the next logical record:

Maybe I was thinking of Crystal Reports Robert? I used to use that also...
