Hi!

Do you have any code in that grid methods? Do you access such things as RelativeRow or ActiveRow properties of the grid? How many columns are in the table? Do you have any field in the table that is longer than 200 characters? There are way too mach cases that I know about grid crash, but never seen grid crash because large number of record in it. Dod you tried just to open table in the command window and browse it by native VFP browse window? Does Browse window crash the same way? If not, than you grid is configured by such strange way that it cause crash, becuase grid control is built on the same engine as VFP browse window.



>Is there a limit on the number of rows a grid can display?
>I have a form with a grid that displays data from a table having ~74,000 records. Problem is that I can only get a little over half way into the records draging down the scroll bar. The grid seems to freeze up showing only some of the records, and not displaying the rest. If I click farther down, I get no response, and after a while I get a Fatal Error C0000005. The table is a historical table and is readonly, so I don't think buffering matters. Is there a memory limit. The table is on a LAN drive and not my local machine. I can get to all the records specifically from the main form, but If I am on a record more than halfway into the table and click on the button that brings up the grid form, the form displays with no records or grid lines or anything and doesn't respond. The done button on the form works, so I don't think Foxpro is hung up. I put a messagebox in the rightclick of the form and the grid record is not the same as the actual recno() when the lockup happens.

The professional level of programmer could be determined by level of stupidity of his/her bugs

It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
