Visual Basic Programming freezing when using do while loop

Question

I have a VB project for school and it requires to use a loop. I'm trying to test it on my computer but each time I press "OK" on my program the program freezes and nothing is added onto the listbox. The only thing that appears new is the scroll bar on the listbox.

    Dim counter As Integer = 0

    If total = 5 Then
        Do While counter < 5
            Marks.Items.Add(studentNumber)
        Loop
    End If

Answer 1

You have to increment the counter

Dim counter As Integer = 0

Do While counter < 5
   Marks.Items.Add(studentNumber)
   counter += 1
Loop

If you want to add 5 items to your list, it is not necessary to use the If statement, because the while loop will be executed exactly 5 times
