I am updating MS access tables with data in an xml

one for new data. I fill the first dataset with the
records from MS Access, the second with data from the xml
Document. Both datasets are populated properly. When the
new data contains records that exist in the existing
Access table but with changes in individual elements, the
matching records in the first dataset are not changed...

I have a ListBox built of a simple custom object for the
ListItems used to be able to hold a Data Value, and a
Display Value, with accessors for each. I have
overridden the ToString method to display the Display
value.
(Two examples that I have seen, including an MS example,
suggest that the DisplayMember and ValueMember properties
of the ListBox can be used in this way, I could not get
it to work using the ListItems.Add method -...

As a Listbox.item, rather than using a string I'm using a ListItems object,
overriding the ToString method
When I add items to listbox.items, my strings are shown correctly.
On the otherhand, when I update the "value" field the listbox doesn't update
to reflect the new value.
What do I need to do to the following code to correct this please (if it's
possible) ?

Hi, I'm doing something where I add custom objects to a ListBox which have
aToString() method overriden so it displays what I want. When adding
instances of these custom objects to the ListBox I also put the same
references in a Hashtable so my program can obtain and modify these objects
without iterating through entire ListBox looking for what I want.
The problem is though, when I update these objects the changes are not being
reflected...

I have a listbox which is data bound to a query that incorporates several
tables.
I want to be able to update the listbox with new items (from another
"master" listbox), remove existing items, etc... then update the db with the
new contents of the listbox after the user clicks on a Save button.
Not sure exactly how to do this. Any suggestions?
Thanks.

In win32 there was a way to 'turn off' a listbox from updating until
you were done adding elements. Is there a way to do this in .NET?

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,...
