So I need to get a button to take the number that a user enters into a textbox, calculate the factorial from that number, and display it in another textbox. I can't seem to get this to come out right.
Here's some of the code I've been playing with. Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click Function Factorial(ByVal txtFactorial As Decimal) As Decimal If txtFactorial <= 1 Then MessageBox.Show("Enter a number greater than 1") Else txtAnswer = Factorial(txtfactorial - 1) End If End Function
Now I have to just work out the code part. Can a function be under a button? I'm getting an error about that. I'm also getting an error about the txtAnswer=Factorial(txtfactorial-1) part of the code.
