No, I'm not using SSL. And in this test program, all three methods are
sharing the same set of variables for System, User, and password.

Interesting that I also asked my friend, who is a VB.NET professional,
and he hasn't ever seen this error before either. Maybe it's related to

I'll keep working on it...

Are you using SSL by chance? Or are you sure you are passing the
username and password properly? Just a couple ideas. I haven't come
across that error before.

OK, I have a test program that uses all 3 methodologies -
IBM.DTA.DB2.iSeries, OleDB, and ODBC. On the OleDB and ODBC
connections, I keep getting the following error:

A first chance exception of type 'System.Security.SecurityException'
occurred in System.Data.dll

The error occurs at the datatable fill statement in both cases.
Obviously, I'll be using the IBM.DTA provider, since that's what works
now. But I'm curious why I'm getting this error and how to resolve it.

Anyone have any ideas?

I am also just learning the .NET. I'm using C# so far, but all .NET
languages are very much alike nowadays.

IBM advises using IBM.Data.DB2.iSeries provider for our beloved IBM i,
so that's what I've been using in my learning projects. It has worked
well so far.

I am using DataGridView component for this experimentation. That also
is working well so far.

I don't think there's anything wrong with using OleDb or ODBC providers.
The only thing is that they're unmanaged code so it sort of goes against
the general .NET philosophy. Since I'm in the academic phase yet, I
wanted to remain in the managed code. When I get to the "real" stuff,
who knows.

I am fairly new to VB.NET. I have a simple project that I'm working on
to get my feet wet. I have the data stored on my i5. This will be a
simple file maintenance app - add/delete/edit records, etc.

I know there are several ways to connect to a database. But, in your
opinion, what's the best way to connect to the i5 to pull data into your
VB.NET app? And why?
