Out Of Memory Error

Hello fellow Database guru's,
I'm using the VB DataControl to handle a large Access 7 database.

The code works fine on smaller databases, but when I attempt to use it on my large database, setting the recordsource to a SQL statement the system generates:
system error &H800040005 (-2147467259).

The error handling routine in the code shows:
Data error event hit err:Out of memory.

Does anyone know what causes this, and how I can get round it?

Thank you!

Which error do you mean
&h80040005  or &h80004005
Most likely the second on E_FAIL.
The system just fails with an unspecified error.

Can you post the SQL for your recordsource?  Also, have you tried executing the exact same SQL inside Access 7?

Are you returning a huge number of rows from your query?  If so, try binding your control as a virtual control.  Grids especially consume large amounts of resources trying to fill themselves with entire recordsets.  Virtual binding can avoid this problem.

One more thing:  Consider re-coding your query to return less data based on user input.  

The narrower you make your select statement, the faster your app will run.  When you're binding large recordsets it's especially important.  You probably already know this stuff... but it's usually the cause of the problem you're experiencing.
