I have run into problems from time to time (and this is
one of those times) using visual basic to access an
external database and perform a basic select from
statement. When the table is extremely large and
performance low, the application freezes. It seems that
it is timing out. Recently I was trying to hit an oracle
database and got the same problem. In this case, I query
a view. When I query a view on a large database, the
progam hangs and never comes back. When I query on a view
on a smaller database, the app runs fine. One solution
may be to create a materialzied view so that my app does
not have to wait for the regular view to finish
executing. However, I wonder if I can control the timing
in my vb app. I am using the current version of visual
studio.net. Is there a way to solve such a problem in
visual basic? Can I make the app wait longer.
Thank you

Norm,
Execute the query on a thread (System.Threadi ng.Thread).

I have a system on a network and want to determine if anyone is currently

An interesting twist is that I have noticed that some users can be connected
(have the front end open at the first form) and even though this links to
the back-end files, there are no ldb files created.
This is so I know when it is safe to compact the back-end files without

I was wondering what is the best concept or idea to mixing visual basic with ASP.net page that runs a SQL query on a database. The Visual Basic would be pulling data from another source that is not a database and needs to place the data results along with the SQL Query results.
Any advice would be helpful.
Thanks.

Hello all,
I am using Visual Basic to open a saved query and then save
information in the query to an array for later use. The problem is
that the same query shows different results when opened directly vs.
when opened by Visual Basic. It is as if Visual Basic is not letting
the query fully evaluate before processing records.
The query is a subtotal query that contains several criteria set up as
"where" in the group-by box. Most of...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
