I have five separate reports, each with around 150,000 lines (sometimes even more). right now, i populate each row one at a time, and it takes around 30 seconds to complete. I noticed a couple of functions in 11.22 called UseReportCustomHeap(), Use RowBatchAllocation(), and CXTPReportRows::ReserveSize(). I put UseReportCustomHeap() and UseRowBatchAllocation() in my apps, initinstance and it made report creation take 40 seconds instead of 30. I removed UseRowBatchAllocation() and it reverted to 30 seconds. I found ReserveSize() in the header, which I call like this:

m_DrawingReport.GetRows()->ReserveSize(25000,25000);

That had noaffect at all. I stepped into it, and it calls CArray::SetSize(), but changes my numbers to growby 1 and maxsize=10. I must be using them wrong.

Does anybody have any ideas?

Thanks!

Hi David,

The best explanation I've found of these methods can be found here:

Look for Sergey's response post, currently near the bottom of the thread.

This is the kind of stuff I wish CodeJock would address more thoroughly - either via the product documentation or in knowledge base articles of some kind.

Anyway, I believe you'll need to produce a release build of your application to notice the effect of these methods.
