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...

I have a Windows Forms application where I need to be able to drag and
then drop onto a datagridview control. I already have the code
necessary to make the drag part work. I am having problems, however,
when I attempt to drop onto a cell in the datagridview. So far
I have done the following with the datagridview control...
1. I set "AllowDrop" to true.
2. In the DragEnter event I put this...

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'm baffled. I have a column in a SQL Server Express database called
"Longitude," which is a float. When I view the table in a DataGridView,
some of the numbers, which only have two decimal places in the database
show up with *15* decimal places and are ever so slightly off (in the
example in the subject line, by about 2E-15).
I'm not doing any operations on this column. It's just running a stored
procedure which performs a pretty basic...

Does anyone know if it's possible to prevent a user from entering a
particular "DataGridView" cell. I simply want to redirect them into the next
available cell but nothing I try works. Setting the "CurrentCell" property
for instance causes no end of problems. If I call it in a "CellEnter"
handler I get the error "Operation is not valid because it results in a
reentrant call to the SetCurrentCellAddressCore function" (which others on

Hello this is probably very simple to do
But i have a DataGridView, which im using to display registration data. I dont want the user to be able to edit/remove/add data. Ive set it all up fine and ive made the table readonly which solves the above problem.
The only problem im having is when i load up the grid i get a grey cell in the top left hand corner which im guessing is the default selected grid. Is there any property to be able to...

When viewing a datatable in a datagridview one of the columns in it is a
"note" field which can be quite long. I would like to have the note
field of the currently selected row of the datagrid display in a textbox
below the datgridview. I currently have it fixed so if you click on a
row the note field from that row is put in the textbox. I'd like this
to be automatic as they move through rows.
Also the note field is one of two fields...

I'm trying to make a datagridview column to act like a datetimepicker column (C#.Net 2005). These are the behaviours that the dgv should have:
1) Initially all the cells of the dtp column should be blank unless they are filled by the user.
2) As soon as the user enters a cell, the dtp control should appear as the editing control of that cell. If there's a value in the cell beforehand, that value is set as the value of the dtp editing control...

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...

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

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...
