Convert Number to Hexadecimal in VB.NET

[shakira]

In this article, we will create a program that can convert a given number into hexadecimal equivalent. Hexadecimal describes a base-16 number system, that is 0 to 9 and A to F.

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 "Convert". Insert two textboxes named TextBox1 for inputting a desired number and TextBox2 for displaying the output in the hexadecimal equivalent. You must design your interface like this:

3. Put this code in your Button1_Click. This will trigger to convert the inputted number in textbox1 and display the output in hexadecimal form in textbox2.

1. Private
   
   Sub
   
   Button1_Click(
   
   ByVal
   
   sender As
   
   System.
   
   Object
   
   , ByVal
   
   e As
   
   System.
   
   EventArgs
   
   )
   
   Handles
   
   Button1.
   
   Click
   
2. Dim
   
   hexNumber As
   
   String
   
   =
   
   Hex
   
   (
   
   TextBox1.
   
   Text
   
   )
   
3. TextBox2.
   
   Text
   
   =
   
   hexNumber
   
4. End
   
   Sub
   
5. 
   

We have first initialized variable hexNumber as a string that will hold the equivalent of a number inputted in textbox1 as we have the Hex function. Hex function returns a string that will represent the hexadecimal value of a number inputted in textbox1. Then the hexadecimal value equivalent in textbox1 will be displayed in textbox2.
