Can somebody tell me how to delete multiple rows in a datagridview
selected by the user?
I tried the following two methods to no avail. I have a myDataGridView
that is bound to
myDataTable's myDataView. The column "Name" is the primary key.
I want to delete the rows selected by the user:

Need some help. I am using datagridview in 2005 with C#. I am calling a web
service and filling the datagridview with the data returned. This all works
fine. Next step is to take a value from one of the cells in the datagridview
and return it back with some other values in an object for another webservice
call. The problem is I dont know how to access a cell in a datagridview to do
this. Im pretty sure you have to do it thru the binding...

Hello All,
I'd like to find out the best way to add a cb column to a dgv and process efficiently. I see at least two ways of doing it.
-------------------------------
1) Add a cb to the dgv, iterate thru the dgv and update the bound fields if the cb has been checked. Then do the update and accept changes. How do I
access the cb and its checked status? How to iterate thru dgv?
Dim cbSelCol As New DataGridViewCheckBoxColumn

I've added a DataGridView and added some columns in the designer, now I want to add some rows with data applied via column name.
Having done some web trawling I've ended up with this:
private void AddRow(string thing,string thingdesc)
{
DataGridViewRow row = new DataGridViewRow();
row.CreateCells(MyGrid); // #1
row.Cells.Value = "Add"; // #2 this makes it work
MyGrid.Rows.Add(row); ...

Hi Everyone,
So I have a datagridview and it has a column called status. It has 3 values: New, Printed, and Shipped.
Now a user can select multiple rows and click "set to printed". I then do a foreach loop on datagridview.selectedrows and change the status to printed. Now the problem is that if the datagridview is sorted by status, when the status is changed from new to printed, that row is moved from being under new to printed and all...

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
Here is the code in...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
