It seems like this should be easy, but it has proven to be quite
painful.
I have an existing dataset, which I used the GetChanges and WriteXML
functions upon to write out a DiffGram to a local XML file. I want to
use this same dataset (in another instance of the application) and the
DiffGram to display the changes in the DataGridView as they existed
after the user made his/her change.

I'm a little confused about DataTable.Merge(). I have two DataTable
objects with the same structure - dtOrig and dtCurrent. The end result
I'm trying to achieve is to get all the rows in dtCurrent that are in
some way different from the corresponding rows in dtOrig so those new/
modified/deleted rows can be processed. My idea was to use
dtOrig.Merge(dtCurrent), and then call dtOrig.GetChanges(). But what I
found is that when the...

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

Hi guys, I'm really hoping that someone can help me...
I have 3 datasets. One that will contain the initial information when I open up the database; one that will pull in information afterwards; and a 3rd to show the changes that have occured since merging #1 and #2.
Now when I'm testing this data, it seems that HasChanges always returns true.
Am I invoking something wrong? Am I not using AcceptChanges and HasChanges properly??

Hello there,
I have the following code; I do this as a work around for a
dataset.haschanges method which doesnt appear to work correctly either
For Each dt As DataTable In myDs.Tables
If Not dt.GetChanges(DataRowState.Added) Is Nothing Then hasChanges=true
If Not dt.GetChanges(DataRowState.Modified) Is Nothing Then
hasChanges=true
If Not dt.GetChanges(DataRowState.Deleted) Is Nothing Then

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,...
