[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.

Thansk marcel

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?
