figure out how to fill a dataset with the same query but run against
multiple SQL servers, the query , table structure and username, password etc
will be exactly the same for each server, the only thing that will change is
the server name. Idealy I would like to get the server names from a seperate
dataset so there could be any number of servers, allthough in...

I know I'm doing something wrong, and it's something simple but I can't
figure it out. I'm new at this and it's only a little more than a
hobby so please bear with me.
I'm writing a VB shell around an Access database. I have an object
that handles the communication of data between my main form and the
database. It creates a oledb data connection, - no problems. It then
builds an adapter and fills a dataset of customer information, -...

I am playing around with making a dataset with the designer in vb.net
2005. I realize you can add parameters to select statement and then
filter off of those parameters. What I would like to do is to take the
dataset that the designer made and add the whole where clause to it at
run time. Is this possible?

I create 2 data OleDbDataAdapters, one with the wizard, and one in
code. I know the adapter created in code is OK because I use it to
fill a data table.
However, when I try to use the same SQL insert statement in the two
adapters, the adapter created with the wizard works fine, but the
adapter created in code gives me an error "Object reference not set to
an instance of an object". The code is below. What am I doing wrong?

Hi !
I get the error below sometimes when retrieving a big amount of data using Datadapter.Fill(dataset,"table"). But when I send the command Fill again, there is no error. Is it a fault of IBM.Data.DB2.iSeries; Version: v1.0.3705 (is there an newer one for OS/400 Version ist V5R3 ?) or is it a hardware faoult (memory of as400 or pc) ?

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
