I am trying to populate a combobox with a lisy of items. I want the 1st item
to be "Make a Selection" and the following items will be names from a table
in my DB (See code below).
When I run the project, the combox box initially displays an empty
selection. When I click on the drop down arrow I see the "Make a Selection"
followed by the other choices.
How can I move everything up so that the "Make a Selection" is the default
value in...

Hi All,
When you add an object to a combobox, and run the application, you'll get
something like this:
System.Windows.Forms.Button, Text: Button1
(for example).
Is it possible to have just the text/value in the object to be displayed in

Hi,
I have a ComboBox of +- 15.000 items in it, via a DataSource. On Top of the
Items-list, I want to add some values, based on a user choise (via a filter
on the DataSource). Does anybody know how I can do this? When just adding
them with ComboBox.items.Insert I get an "Items collection cannot be
modified when the DataSource property is set".
Does anybody has a solution for this? i'm surely not the first to do this
:-) I'm using...

Hi,
I am new to .Net.
I am using a Combo Box in my windows forms. I am adding the items by
creating the instances and adding the same to the list.
My questions/doubts are:
1. If I have 25 to 30 options in each combo box and like that if we have 6
or 7 combo boxes in a form, isnt it a problem in creating that number of
instances everytime the form is opened/activated
2. How do I dispose the Combo Box items.

I wanted to add a Combobox to a toolbar... Kind of the look you get on
VisualStudio's toolbar.
I've been able to find some VB 6 samples, but the placeholder option is no
longer available for ToolbarButtons...
Does anyone know how this could be done?
Looking forward to hear from you,

I need a right-click menu on a form list control with combobox
controls.
I used View->Toolbars->Customize to create a toolbar.
I added ComboBox through commands tab.
I set properties to Popup making it a shortcut menu.
I have no problem linking it to the list control.
The menu comes up when I right-click the list control.

I have a ComboBox and a List of objects to popolate items.
I use the DataSource property and not the List collection:
List<foolst = new List<foo>;
//add elements into the list
//...
comboBox1.DataSource = lst;
This work fine, items appear.
Now I have a button near the combo box and I want to add a new element

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:

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,...

Hello
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...
