Convert Number to Hexadecimal in VB.NET

Submitted by donbermoy on Thursday, April 10, 2014 - 13:46.

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: design

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.

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

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.
