Find Min/Max from 1 textbox

I'm trying to find the Min/Max value of a textbox that has 1 variable and display it to the user, so the variable changes everytime the button is clicked. How would I find the maximum value of something that is constantly changing? The trick is that I can NOT use if statements or case statements. I'm totally at a loss here.

Ok, the things that limit you.

  • One variable
  • no if/case statements

The lesson seems to revolve around using Math.Max().

Math.Max(), as we can see on MSDN returns

the larger of two 32-bit signed integers.

The one variable we are going to use needs to exist outside of the button's click event. So, just make it a class variable.

This variable will essentially store the largest value. Math.Max() returns the largest of two values... see what I am getting at here? You can pass the current largest variable as a parameter to Math.Max() without any issues.

Example:

Dim max As Integer

max = Math.Max(1, 100)
'max would be 100
max = Math.Max(max, 10)
'max would be 100
max = Math.Max(max, 1000)
'max would be 1000
