This time, let’s learn how to get
factorial numbers in VB.Net. If we say factorial number, it means a number which is
multiply itself to its decreasing numbers and it is denoted by the symbol (!). Like for example the factorial number or value of 5. This is how it looks like, 5! = 5 x 4 x 3 x 2 x 1 = 120. Now, let’s try doing this with codes in VB.Net. Just simply follow the instructions below.
Creating Application
Step 1
Open
Microsoft Visual Studio 2015 and create a new windows form application.
Step 2
Add the Label, Button and a TextBox inside the Form.
Step 3
Double click the button and do the following code inside the
sub procedure for getting factorial numbers.
Dim n, f, i As Integer
f = 1
n = Val(TextBox1.Text)
For i = 1 To n
f = f * i
Next
MsgBox(“Factorial is :” & f, vbInformation, “Factorial”)
