Hi Bruce,

I don't know a whole lot about the subject but I did just read something that could confirm that.

Appearently VFP keeps an internal buffer open for itself. So VFP may have never written that hidden buffer back.

I'm sorry but I can't remember where I read it. I thought it was in 'effective techniques' but I can't find it now. If I do, I'll let you know.


>I'm offering a theory here that would account for lost data I posted about this morning. There are 3 tables on the server. A user opens them up EXCL in an app, does an hour of edits, the machine crashes, and all the edits are lost. This is with table buffering, and in spite of constant Tableupdates during the editing. All tables have edit timestamps, and no stamps were made for the editing period. All tables are fine otherwise, the editing was re-done without trouble.
