Get and Display all Computer Ports in VB.NET

[Ikuyy]

In this tutorial, we will going to create a program that will get and display all the computer ports in vb.net. COM Ports are serial communications port on a PC.

Now, let's start this tutorial!

1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application.

2. Next, add only one Button named Button1 and labeled it as "Get Computer Ports". Insert a ListBox named ListBox1 for displaying all the COM Ports. You must design your interface like this:

3. Put this code in your Button1_Click. This will trigger to get and display all the available COM Port in the ListBox.

1. Private
   
   Sub
   
   Button1_Click(
   
   ByVal
   
   sender As
   
   System.
   
   Object
   
   , ByVal
   
   e As
   
   System.
   
   EventArgs
   
   )
   
   Handles
   
   Button1.
   
   Click
   
2. For
   
   Each
   
   portName As
   
   String
   
   In
   
   My.
   
   Computer
   
   .
   
   Ports
   
   .
   
   SerialPortNames
   
3. ListBox1.
   
   Items
   
   .
   
   Add
   
   (
   
   portName)
   
4. Next
   
5. End
   
   Sub
   

We have created a For Each loop statement that has the variable portName as String that has all the value of the Serial Port names. This For Each...Next Statement repeats this group of serial ports to be displayed in ListBox1 as we have the Add function of this control.
