Random Number Generator using VB.NET
Submitted by donbermoy on Monday, February 10, 2014 - 14:12.
Hi! this is my another tutorial for VB.NET entitled "Random Number Generator".
Some of the systems and applications today are using a Random Number Generator to generate random id number which will be used for their id in the database or let's just say an application by guessing a number.
So, now let's start making this program!
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, and choose Windows Form Application.
Next, add one button and named Button1. Have it also labeled as "Create Random Number". Follow this designed layout:
Next, in the code tab, create a code for your Button1_Click. Type this code below:
We declare 
Click OK button in the MessageBox again. It will generate again a random number like this:
Lastly, click the OK button. It will generate again a random number like this:
We can only generate random number three times as we conditioned For i = 1 to 3.
Download the source code below and try it! :)

Next, in the code tab, create a code for your Button1_Click. Type this code below:
- Public Class Form1
- Public random As New Random()
- Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
- Dim i As Integer
- For i = 1 To 3
- Next
- End Sub
- End Class
Public random As New Random() as our Global Variable for instantiating a Random Object (New Random()) that holds the variable random. We also initializes Dim i As Integer as our integer so that we can generate three random numbers (For i=1 to 3) when we click OK button in the MsgBox.
MsgBox(Convert.ToString(random.Next(0, 1000))) syntax is for displaying the random number. random.Next(0, 1000) initializes a random number from 0 to 1000, then the output is converted into a string using Convert.ToString syntax.
Now, click your Button. It will now generate random number like this:
Click OK button in the MessageBox again. It will generate again a random number like this:
Lastly, click the OK button. It will generate again a random number like this:
We can only generate random number three times as we conditioned For i = 1 to 3.
