CRW 7 RDC performance

[CW2002]

Because of concerns for the licensing restrictions imposed by CRW 8.x, I had to downgrade my application back to using CRW 7.0.

Now I'd like to stick with RDC when downgrading my application to version 7 (my original code is written using Crystal Automation Engine).

However, I have found that using ActiveX Viewer under ver 7 is extremely slow, compared to ver 8.x (by a factor about 40 times when I use subreports).

I am wondering if anyone has got any tips or tricks to speed up the performance here. I am still using the same code that I used in version 8 to load report in RDC, as per follows:

CRViewer1.ReportSource=MyCrystalReport
'MyCrystalReport is a report object
CRViewer1.ViewReport

Or am I better off going back to my original Crystal Automation Engine code?

Any idea?

Thanks in advance

One of the new features when CR8 was released was vastly improved performance!
From a runtime perspective, ignoring web reporting, there is no difference between 7 and 8 licensing. Andrew Baines

There are additional run-time license restrictions on so called "report distribution system" that could give rise to the requirement of having to acquire Broadcast License (at 20K a pop per year minimum)!

The additional charges are where you're automating distribution to more than 50 users.

We do automatically distribute stock information via email, customized to the top 10 most ordered items for each customer respectively, to our customers.

This is not something that can be automated using CE or Info, and thus we had to write our own code for it. (It's possible to do it using Info, but we would have to schedule one report for each customer, and add/delete thoese jobs when customers come and go, and it would be one heck of an administrative nightmare).
