application.
The Windows Form application will call the WebServices to retrieve data from
database. The data will be returned as DataSet.
Now, here's the problem. On .NET Framework 1.1, if any rows in the dataset
returned contain errors (marked by calling the SetColumnError() method or

I have a web interface where the user types in ID's one at a time. After an
ID is typed in, a button is clicked and the button click event has code that
does a query and returns a data reader and then appends the data to a
dataset that is built in the Page_Load code in the if(!isPostBack) block.
When I try to add a row in the button click event code I get an error saying
that "Object reference not set to an instance of an object". I'm...

OK, I have filled a DataSet with an SqlDataAdapter and I just want the data
in one column of one row. How can I do this since the following gives me
the infamous 'Object reference not set to an instance of an object' error:
strng = datset.Tables("Users").Rows(0).Item("Users").ToString()
My table is called Users and I want the first row, and the only column is
also called Users.
I broke it down by declaring a DataTable and a DataRow etc...

I need to custom build and use a dataset in c# to use with xml. Does anybody
know where I can find out how to do something like this? I was going to
create a class that generated the dataset and its data to hide all of the
complex (or should I say the huge chuncks of code) from the page itself.

g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
