Hello Sir,
This is Chandra and Working as Software Engineer. I got a really weird
problem with ComboBoxes.
I have set the ComboBox DroppedDown Property to true.
Now the actual problem is When the ComboBox DroppedDown is Shown I have to
actually click twice to get out of the form or need to click twice to do
anything.

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;

Hello,
I know this has been discussed a lot already because I've been searching
around for information the last few weeks.
I'm trying to implement a DataGridComboBoxColumn class. I've found
several examples on the web. They all seem to have problems, though

VB 7.1 and windows.forms.
I have a comboBox on a form.
When the user goes with TAB-Key to the comboBox,
the comboBox should dropDown the ListBox automatically
and show ALL entries.
The user has no possibility to use a mouse !!
How can I program a automatic dropDown ( Showing all entries ),

Hello.
I want a combo to open automatically when it gets the focus. I've been
looking for it on the Internet, but I've just found with the API.
It'd be OK, but it uses combo.hwnd, and I don't know which is the
equivalent to hwnd in VB.NET.
Can anyone help me in how to open the combobox, or how to work with the
hwnd for it?

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
