I'm looking to write a very simple program which asks a user to enter a number between 20 and 50. The program would display the letter 'I' in a textbox to correspond to the number the user entered (i.e. if the user entered 34 then 34 I's would be displayed. I'm not entirely sure of what commands would make this happen.

View 5 RepliesI have set up text boxes for user to pick a number 1-20 and to enter a word as well. Then, press submit button.

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.

I am trying to run a nested loop; it should call a result from a MDB database. Which it does, when I run the single loop it goes thru all of the entries. But when I try to get a number to display twice it stops on the second entry. Having it display the number twice is just a test to make sure it does work, I am going to modify it after I can prove the loop works. The count on the Message Box is correct, but the number displayed is wrong?I want it to display each number twice and then move on to the next number. [code]
