I have a single record DBF (not a view, not a free table) associated with an entry form. If I make a change to a textbox, then close the form, the DBF is not updated unless I move that cursor out of the textbox. I know this is an old problem and have solved it elsewhere by writing the value to the controlsource's field. However, in MM, I've traced the problem to the form's WriteBuffer() method (CBizObjForm class) which does the same thing (far more thoroughly than I did).

But, that method has a line:
IF CURSORGETPROP('Buffering') != 1 AND GETFLDSTATE(0) % 2 = 1

If that IF condition evaluates to .T., the controlsource field is updated. In my case, it's evaluating to .F. Further testing shows that CURSORGETPROP('Buffering') is indeed 1. Yet, in the BO builder, I've set the Data Access Buffer Mode override setting is 1 (use form setting) and the form's buffering property is set to 2 (optimistic).

Can anyone suggest what's going on? Or better yet, how to fix it?

Thanks,
Ken
