I think this is the right group to post to, so here goes.

them into a datarow and using that datarow to update the database, but
its not working. The btn_update is where I am sending the information
back to the addclient...

The .NET 2.0 documentation states the following:
When using a DataSet or DataTable in conjunction with a DataAdapter & a
relational data source, use the Delete method of the DataRow to remove
the row. The Delete method marks the row as Deleted in the DataSet or
DataTable but does not remove it. Instead when the DataAdapter
encounters a row marked as Deleted, it executes its DeleteCommand
method to delete the row at the data source. The...

Mobile SQL 2005.
I need Data from a Database to be shown in a DataGrid, this works.
But now I want to be able to get the Data of the selected DataRow, for

I have the following code:
//delete the row in the table that has ID of 1. This line works fine.
DataSet.Table.Rows.Find(1).Delete();
//Accept the delete changes to the table. This row returns 'object set to a
null reference' exception. Why?
DataSet.Tables.Rows.Find(1).AcceptChanges();
Why does this happen if the DataRow.Delete method page on msdn says that you

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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,...
