sharok,
The FiveWin 1.92 version is quite old and several things does not work well but I think the EditCol() method (not the lEditCol() method) should exist. It is the non-modal cell editor. If not, sorry.
I have the spanish 1.95 version that I adapted with classes developed by FivewWin users droped in the FiveWin NG. Many of theese classes are included in the newer versions. (the newest is 2.3).
Personaly, I would not let the end-user edit a cell in non-modal mode. I use only modal dialogs and that saved lots of troubles opening several times the same dbf file at the same time and GPF´s because the user left open a lot of child windows and now is working wit a new one.
Regards
Sandor
