except for one issue.

anywhere else, the dropdown gets hidden. i am trying to replicate
this behavior and have tried using the Leave and LostFocus events. i
have had marginal success when my dropdown is visible and i...

Howdy, all.
Appreciate your help. Have a one to many relation between a client and
visit table.
In the visit subform, I have a visittype and counselor field which are
comboboxes. If I set either field to drop down via Me.dropdown in the
GotFocus event for the field, each time the client record changes the
visittype or counselor field drops down - only have the GotFocus event set
to one combobox at the moment - unless I move the cursor...

I use the DataSource like below to fill a Combobox:
comboBox1.DataSource = dataSet1.Tables;
comboBox1.DisplayMember = "ProductName";
When the user types any keyboard key i use the DROPDOWN
property, like below, to show all combobox itens:
this.comboBox1.DroppedDown = true;

For fun, I am developing a combobox control look-alike.
The only way that I was able to accomplish creating a dropdown list was to
basically show up a form right underneath my custom combobox that acts as
the dropdown. This form does not have any borders on it and it only hosts a
list box control so it looks like a real dropdown.

I've looked high and low for some code that will allow me to have a combobox
with a flat borderstyle. I found a few examples, but nothing that was
really usable for me. I had the following criteria that I wanted to meet,
but nothing did:
- No reliance on a separate library
- No unmanaged code
- Easy subclassing of System.Windows.Forms.Combobox (i.e. no custom control
monstrosity)
- No extra funky features that I didn't need

Hello (again),
Within my datagrid I add a control to the datagridtextboxcolumn when
the underlying textbox receives focus as follows:
Combobox1.Size = New Size(Datagrid1.GetCurrentCellBounds().Width + 3,
combobox1.Size.Height)
sender.Controls.Add(Combobox1)
This works great. The problem is that when focus is set on the

Hi I am still having problems with Tabbing through a DataGrid with a
DataGridComboBox Column.
I need to allow the User to Type the value into the ComboBox so consequently
its ComboBoxStyle is set to DropDown. This causes the Tabbing to work
incorrectly. Even though I am consuming the Windows Message WM_KEYUP, it
still Tabs through the ComboBox Column on to the next Column.
I found if I do not give the keyboard focus ie remark out...

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'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...
