Hi,
I have an original dataset. It is copied to 2 different forms. Each form
adds a new row to the same table in that dataset. When I merge these 2
dataset back to original one, the 2 new rows merge to one!
My question is how I can still keep them as 2 rows in that table, not merge
to one?
Thanks.

be very simple to solve, we were just point the mail merge data source to

hello,
i have a web app that allows users to query our oracle db and produce a
dataset of report data. they then have the option to serialize this
data and store it in the database. later, then can re-run the report
and get fresh data. now, they would like to be able to compare the
fresh data to the stored data, getting a break-down of
added/deleted/changed rows.
on the surface, this sounded plausible -- by deserializing the stored

Hi there,
Can anyone explain the following (very) simple scenario.
1) I make an exact copy of my "DataSet" and delete one record from a given
table (in the copy)
2) I invoke "DataSet.GetChanges()" on the above copy and pass the results to
"DataSet.Merge()" on the original copy
3) If I now inspect the original copy, it shows that the record has *not*
been deleted from the table. However, a call to "GetChanges()" does show my

I am trying to get my head around dataset merging but despite a little
research I could still use a pointer (or ten). Basically I want to perform
an outer join operation on a dataset (created from a file operation) and the
resulting sql query based on the contents of said dataset. Effectively I
would end up with two dataset tables in my application. If I were writing
this to action from two tables it would be thus:
SELECT ds.id, db.*

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,...
