Is there a way to compare the values of portions of two rows? For example,
can I test if RowA, columns A,B,C are equal to RowB columns A,B,C and all
the while ignoring columns D,E, and F?

In my case, the column is defined as PK in Enterprise Manager. My issue is
adding a new row to a dataset which includes the PK/Auto increment column.
Without setting a value for that column, I get a Null error on the
column.add method. I'm going to get to reading your suggestion.

I've created an object that collates data from multiple calls from separate
databases. The primary key column is a string, the idea being that the most
recent calls' values will possibly overwrite values from prior calls to
other databases.

Is there a way that will allow a column to be updated within a DataRow
without affecting the RowState?
I have a Datatable filled with data, but need to be able to update a column
with a new value for display purposes, but do not want it to affect the

I need to copy records from table A to a new table B (overwrite if exists)
based on a flag field not set in table A. I then need to set flag for all
records in table A that are also in table B. How can I do this in ado.net
using vb.net?

Where can I go to read about performance issues when
dealing the sql connections in ADO.NET?  Specifically, I
am looking for some place that discusses the pros and cons
of using a single connection vs. using multiple connections.

i've already sent a request concerning row deletion in a datagrid.my

How do I build a dataview.rowfilter that will return a row for each

Is there a way to perform a compute using a DataView that is already
Filtered?
I am trying to do some statistics on data from a dataset, grouping by day.
I have my DataView set up to filter out the appropriate range, project, etc.

I have a stored procedure that returns a single row, depending on the
condition the stored procedure will sometimes return some null columns. Is
there a way to evaluate if the control is null and then suppress it from
display.

I have a table in a dataset, and I want to find if a record or row exists in
the table of the dataset where 3 separate columns have values I pass. I
tried using the row filter property but I don't think I am using it right.

I'm having some trouble with a typed dataset that contains fields that
should technically be considered null. I've loaded my typed dataset from SQL
server. One particular table contains only one row. It has two fields:
Agency and CaseType. In the SQL Server table, the Agency field ...

I have the following situation which I use often, but now produces strange
behavior:
- I have a class derived from a typed dataset.
- In this class I defined a method Read for reading data from a web service.
