Two things that bog down Access 2000 and 2002 are Name Autocorrect and Subdatasheets. If you turn those two things off, you'll see an improvement in performance. Subdatasheets also need to be turned off in the backend.

Subject: [AccessD] Performance ADO - DAO or ??
Dear group,
It has been a while since I looked into this group. My daughter (7 months) took up most of my time recently. But work goes on so I would like to ask you the following.
I am strugling with the following. I have about 6 access 2000 applications distributed among several customers. All database use DAO and have a FE and BE. It works fine but know customers start complaining about performance. Expecially on a network envirnement. I have
- Looked through all the queries and changed all the SELECT * queries with only the data wich is used
- closed all recordset and database connection at the end of eacht function of module.
- Removed databound forms as much as possible. This is a lot of work and I do not know if i want to do this.
But this all did not improved much.
I am thinking about the following
- Is it a option to move to ADO instead of DAO. Does this improve performance?. In my tests it does not matter much but perhaps I am missing something
- The performance analyser in Access tells me to use fewer controls on a form. If I do this does this improve performance
- moving to sql server. But this will cost my customer a lot of money and the won´t be happy.
Any suggestions, ideas??
I am thinking to rewrite the programms to VB, anyone experience, tips, tricks in this.

Subject: [AccessD] ado recordcount
I am opening a recordset (raw table) that contains records. Move last, move first. EOF and BOF are both false.
Recordcount = -1
What gives? How do I tell how many records in the recordset?
