I have a datagrid in a windows forms application. The datagrid gets its
data via a web service. Users can modify rows in the datagrid then post
their changes. However, when changes are made the rowstate remains
"Added" for all the rows--those that were modified AND those that were
unchanged. Here is the code I am using to test (dsitems is the
underlying dataset):
private void btnSave_Click(object sender, System.EventArgs e)

I have set a DataTable and one of the columns I set "AutoIncrement" to True.
I then populate the Table by setting the columns to values then add the row
to the table. I inadverently set the AutoIncrement Columns to different
values but didn't get any errors. Should I be able to set the value of an
AutoIncrement Column? I would have thought it couldn't be done as the column
value was set when a row was added.

I have setup a master-detail dataset and have a couple of textboxes from the

I have a navigation pallete with the usual arrows. All arrow btn's are

I have a Windows form that displays a database table in a DataGrid. When you
click on a row, the row's values get copied to bound TextBoxes below, and
when the "Save" button is clicked the database is updated (as is the DataGrid
row) with changed values in the TextBoxes. Here are some observations:
1) When changes are typed into a text box and "Save" is clicked, the changes
are reflected in the DataSet.Tables().Rows().ItemArray value, but...

- all tables have a primary key (PK)
- many of the PK will become FK(Foreign Key) in other table(s)

I'm getting really strange behaviour where the data source RowState is not being updated to modified in some circumstances.
I place my controls on a form, bind them through a BindingSource control to a DataSet. If I don't do anything to the DataSet other than load data normally through TableAdapters everything works fine.
If I load a table(static data for ComboBox) in the DataSet manually; the DataSet now says it has changes. I call...

Hello All, I could use some help on an error that is just now popping it's
head up.
Seems that the autoincrement numeric has hit 32,767. The autoincrement is
used in various locations in the database, but in this case (log sheets), we
have hit 32k log entries over the past 2 years.
Is there a simple switch to set the autoincrement from integer to long
integer?

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
