I was about to deploy my first website on the Internet only to discover that
the dataAdapter.Update() throws the Server Error in the third underline. It
was working fine before.

If an object implements the IDisposable interface, should I always call the
Dispose method or is just setting it to null and letting the GC handle it
sufficient? Here is the pattern I've been using but wasn't sure if it was
necessary:
DataAdapter da = null;
try {
// Some logic here...
} catch (Exception ex) {

Hello,
Let's say I open a form and populate a grid and a few textboxes with a
dataset, something like this (I won't go into detail, because the code does

Dim DataSet
Dim Connection
Open Connection

I know datasets have been beaten to death in here, I have what is hopefully
a simple question about the integrity of a dataset when used in an
application.
Scenario:
User A and User B are updating data in a SQL database via an application
that utilizes a dataset, dataadapter and datagrid.
User A retrieves data from data source and sits on the data for some time
User B retrieves SAME data from source, changes data via teh datagrid and

I keep getting a concurrency exception the second time I make a change and
attempt to update a dataadapter. It appears this is by design, so there must
be something I can do to avoid it.
Example:
I have a dataadapter that contains one table with one row. I change the
value of the 'FisrtName' column in that row from Jack to John. I call

column in that same row...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
