Hi all,
I have a control that extends the ComboBox object. It
updates the selected item based on what the user enters in
the text area.
In the OnLeave event of the combobox, the selected index
is set to the proper item. However, when accessing its
selectedindex later it has reverted to the previous
value. The selectedindex value is always one behind what

Hello,
For my new Windows application, all I want is to create an initial
form to demo to the user to show them how it looks like with some data
on it. So I figure the fastest way is to create some comboBox-es to
show some data on them manually entered in the code without connecting
to the database yet. It should be simple but somehow I can't make it
work.
First, I drag a comboBox from the ToolBox to the form. Then,

ComboBox databindng Problem
== How the ComboBox is setup and used:
My comboBox is populated by a lookup table. The ValueMember is the
lookup table's Id and the DisplayMember is the text from a
corresponding field in the lookup table. In my data table we store the
ID in what I will call the 'key' field.

Hi Everyone,
I am at my wit's end here. I have a combobox (combyQueryTitle) that I
need to use in order to select a query for my database project. Therefore,
I am using the comboQueryTitle_SelectedIndexChanged handler to, when a new
selection is made, update the query and refresh the display. The only
problem is that the program seems to inexplicably start with the
..selectedindex property at -1! This makes no sense to me. ...

Can I use a bound ComboBox for both browsing and editing?
I'm working on a small, standalone database application using Visual
C#.NET 2003 and an Access data file.
In order to keep the number of different screens down to a minimum,
I'm trying to use the same Windows Forms for both browsing and for
updating. This works fine for TextBoxes, but I'm running into
problems with my DropDownLists (ComboBoxes).

I've spent the last four hours Google searching for a way to disable
items in a Combobox. I found one example in C++ which I can't get to
work and another in C# that I couldn't get to work either.
Does anyone have some good code for an owner-drawn combobox?

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

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,...
