Disable editing in combobox control in VB.Net

This is a very simple tutorial yet it's very helpful. We use combobox to dispaly an editable list of text/string but what if we do not want or allow our user to edit the items in a combobox? what we want is to select from list of choices. This codes will disallowing our user to modify or edit the text/string in our combobox control.

First drop a combobox control in the form and name it. Go to the code and declare a boolean variable and set it to false:

Public Class Form1
Dim editingInCombobox As Boolean = False

then create keypress event in the combobox control (creating event in vbnet code window).

Once you done, add the following line of codes in the keypress block:

If Not editingInCombobox Then e.Handled = True

Beep()

editingInCombobox = is the boolean variable we declared
Beep ( ) = Sounds a tone through the computer's speaker.

That's it, I hope you like it.
