People, I am at my wit's end.
I am using the exact code from
http://aspnet.4guysfromrolla.com/articles/071002-1.aspx
And yet, the code does not manage to update the database. When I go to
update my database, I am able to get the form fields, and I am able to
replace the data, but when I go "update", the old data remains.

How can I fix this? When I do the below I get the error message:
"Cannot insert explict value for identity column in table
'Employees' when IDENTITY_INSERT is set to OFF."
To get this message, I click the Add button to add a new row to the
database, and then I click the Update button to save the new database
to the external memory.
The methods I used are below.

Hi guys -
I have written a form, and a stored procedure to update the said form.
It really is as simple as that. A user can go into the form, update some fields and hit the update button to update the information which is stored in a SQL database.
In testing we noticed that the form was updating correctly but the update mechanism was also updating the first record of the table in the sql database every time. No error messages are on...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
