Thinking two things,
1- Creating a userControl -yeah you guessed it, a multi column drop down
combobox - I've looked at several articles and did not find what I need, one
that's bindable and that I can use in a datagrid view.
2- Extending the datagridview so that it can be added to the list in the
column types when editing columns in the datagridview.
I'm really getting PO'd at Microsoft for not including a multi column
combobox both a...

VS2005 and I have a DataTable displayed in a DataGridView that needs custom
sorting, with the DataSource of the grid set to the DataTable and the
SortCompare event just won't fire.
Then I found this in the docs "This event occurs only when the DataSource
property is not set and the VirtualMode property value is false"
This seems really odd but may be true. I can't see what the purpose of this
event is then, how else will one use the...

I have been trying to figure out how to use DataSets, BindingSources,
DataGridViews, and XML together, but it is a challenge. I understand how
to populate a DataGridView with XML basically as:
DataSet ds = new DataSet();
ds.ReadXml(@"\usr\tmp\sample.xml");
dataGridView.DataSource = ds;
dataGridView.DataMember = "targetElement";
What I found through experimentation is that the DataMember may specify

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

Hey everyone...
I've got three problems with a custom DataGridView column I've built
following the "How To: Host Controls in Windows Forms DataGridView
Cells" article. The base editing control is a ComboBox which is
similar to the built-in Combo column but will hopefully be more
flexible.
First: I am using this control in multiple columns which _should_ hold
unique items. However, the items added to column A are visible in

I'm doing a Component class that inherits from DataGridView.
One thing that it does is to add a default column in the grid.
I put the code for this in the class and when I drag the control to my form
i VS2005 it appears just as expected in the designer.
The problem is that when I run the application it adds the column twice so I
get 2 columns in runtime.
The reason is that when I drag my custom control to the form it generates
code i the...

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...

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,...

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...
