Upgrading from 4.6 to 8.5 1

[wawanz]

Hi, I'm a VB6 programmer and have always used the Crystal Reports (version 4.6 I think) that came with VB6..

I'm thinking of upgrading my Crystal Reports to 8.5 BUT I have worries: will it have the same procedure to call the report from my VB6 application? Example:

when I want to show a report (4.6), this is what I do:
Reportfilename=...
LogOnInfo(0)=...
SQLQuery/SelectionFormula=...
Formulas(0)=...
Action=1

People have been telling me to upgrade because of the limitations in 4.6,...but I'm always worried that the later versions of CR wouldn't use the same procedure ('cause then I have to spend time to re-code my applications).

Opinions and info please...

You must be using the Crysal Report Control (.ocx) currently. While the OCX is still supported up to 8.5, as of version 7 (I think), Crystal introduced the Report Designer Component (RDC). They've been suggesting for a few years that developers move from the OCX to the RDC. Why? Because the OCX is no longer supported after Crystal 8.5...

If you purchase 8.5 Developer, there's a guide that comes with it with a chapter on migrating from the OCX to the RDC. I also believe the same document exists on the Business Objects site.
