The timer control allows you to set specific time intervals until some code has to be executed. Here is how you program the timer control in VB.net

Difficulty: Easy

Instructions

Things You'll Need:

VB.net

Step 1

Open VB.net and create a new windows application.
Step 2

Listbox

Add a listbox to the form. We are going to use the listbox to add items to it every time the timer control gets exceuted.
Step 3

Timer Control

Add the timer control to your form. Notice how the timer control is not actually shown on the form but instead in a different panel at the bottom.
Step 4

Timer Properties

Click on the timer control and press the F4 key to bring up the timer's property window.

Step 8

Code

In the tick event we are going to add the code:
ListBox1.Items.Add(ListBox1.Items.Count)

What this does is add to our listbox the number of items in the listbox each time the tick event executes which we set earlier to 1000 or about every second.
Step 9

Run the program by pressing the F5 key on your keyboard.
Step 10
