>>>When I select a cursor in the DE, and drop down the property in the prop sheet for BufferModeOverride, I see six

>>Strange. Probably options 3 and 5 (optimistic buffering) are the most important ones, but that is really no reason to eliminate all the other options from help.

>>For your information, here is the help (more complete) for VFP 6:

>>0 None. No buffering is done.
>>1 (Default) Use form Setting. Uses the BufferMode property set at the form or form set level.
>>2 Pessimistic row buffering. Locks the record and buffers the changes until the record pointer moves. You can use TABLEREVERT( ) to undo your changes.
>>3 Optimistic row buffering. Allows edits to a single record and locks the record only when it is written to disk. You can use TABLEREVERT( ) to undo your changes.
>>4 Pessimistic table buffering. Locks each record edited, but records are not written to disk until TABLEUPDATE( ) is called. You can use TABLEREVERT( ) to undo your changes.
>>5 Optimistic table buffering. Allows edits to all records and does not lock them until the records are written to disk with TABLEUPDATE( ). You can use TABLEREVERT( ) to undo your changes.

>the form's setting", and 2-5 are the same as CURSORSETPROP,so it sort of makes sense.
>Although I agree - all should be in the help.


This sure looks like a Help bug. Please post it on Connect.
