I ran the sample application called Petstore from msdn.
Everything went fine until I tested Update button on the
web form to update the database through Datagrid.
I have been searching the web to track down this error,
but none of them really explain this problem/solution
very well.
I tried hard to debug this, but debuggin itself was
impossible.
The error message is as follows:
Server Error in '/Pets' Application.

There is an article Microsoft Knowledge Base Article -

In this Pet application, Datagrid_Update Command is not
even accessed due to this error.
Please somebody provide explanation and workaround for
this.
I'd appreciate sooo much.
Thank you.

Hello all,
I've been trying to figure this out for a few days now, and still have
no clue what's going on...
I have a few related tables in MS Access (Clients, Cars, Sales), and a

Here's a catch - whenever I select a client, and then find a car which
belongs to this client, and click on empty space in datagrid (that is
in gray area below rows) - I get "Index was outside the bounds of the
array" error......

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
