Maybe, if there's only one group, allow to not show the list of groups since it's kind of useless to reserve space to show only one item.
Packing in-memory table
Filter on LargeInt Int64 values
It works, thank you.
I'm using the released version 7.0.1. You said that it was fixed in 7.0.2, but it is nowhere to be seen. If you check the latest version of the file dbf_prssupp.pas (https://sourceforge.net/p/tdbf/code/HEAD/tree/trunk/src/dbf_prssupp.pas) at line 356, the variable IntValue is still of type Integer instead of Int64. This cause a range check error at line 367 ou 369 (IntValue := Val) for very large values of Val. I hope it's just a commit problem. If not, I'll try to make a sample.
Is this correction is supposed to be in SVN? Beacause it is not.
