Hello,
I am beginning to write a custom combobox control. Right now it doesn't do
anything special. I created a class that extends ComboBox:
public class TimeSelector : System.Windows.Forms.ComboBox
and in its constructor I call Populate:

I fill a table in a dataset with values that will be used by a combobox
for the combobox's items. The combobox is a drop down list that only
allows the user to select from the list but not enter any new values.
What I need to do is include a blank row in the list so that when it is
selected, the SelectedValue property returns a Null. I don't want to
add a record in the database with some field set to null because this
would have to be...

Is there any way to detect when an item has been added to the Items
collection of a combobox or listbox? I am inheriting a Combobox and want to
validate items before they are added to the combobox, but I can't find
anything that will let me do that.

How can you display more than one field in the displaymember property of a

Hi. New member here
Im sat at work, pounding my head off the desk because this tiny bit of simple code refuses to work.
The sub is intended to pull data from the "companyname" column in the "cmSelectAllCompanyNames" table, and put all the company names it finds into the "cbFilterCompanyName" combo box.

Greetings,
I have to load 30,000 unique names into a combox. Filling a dataTable takes
only a few milliseconds. But populating the combobox and displaying the list
takes several seconds - way too long. A user selects a name from the
combobox and runs a query.
Originally, this combox was on a form in an MS Access ADP which was linked
directly to our sql server. The combobox populated withins millisecnods.
How can I achieve this...

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,...
