I'm using an in-core DataSet as an image of my application's
'database' (a multi-table Access97 mdb file). Updates are made to
the DataTables within the DataSet via forms with bound TextBoxes,
then written to the database... or at least that's what's supposed
to be happening.
Unfortunately, I've discovered that while it appears that when I
create a new record/row I'm successfully updating the Access
database, once the Update is...

Hello,
How come when I add a new row to my dataset table it shows up as changed
(agencyData.Haschanges() = True) but when I delete a row the dataset thinks
here are no changes(agencyData.Haschanges() = False)????
The bizaar thing is the row count before the delete and after is different
so it definately is being deleted but I cannot update my main database table
because the dataset thinks there are no changes?

OK i have came to the conclusion that since this app will be run on multiple computers that loading a complete database and then updating on exit is a moot point. I have tried several ideas submitted, but i am unable to get one of them to work completely. Here is the code i had before i realized that when i filled the dataset in the form load procedure that it would "ruin, replace, mess up" the dataset named the same thing on the other form....

My experience with databases using C# has been pretty limited thus far.
Mostly I just use a SELECT statement to populate a DataSet, which is
just read-only (mostly for display on a web page), or maybe go so far as
to build an UPDATE or INSERT query with a couple parameters and just
execute it against the database. Currently, this is all done within a
web service, which acts as a kind of protective barrier between the
actual database and...

Im using the new binding features of Visual Studio 2005. I have done the
steps to create a bound data source, and selected all 40 tables from the
database. The wizard generated the necessary code for the dataset and can be
seen in the solution explorer under "db_exampledataset.xsd".
My worry is the size of the dataset definition, specifically that the
"db_exampledataset.Designer.cs" is huge, about 51000 lines of code, the

Overview:
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,...
