Like many programming languages out there, VB 6 also has loop control statements. In this article, you will learn about While loop which helps in repeating a block of code until loop is terminated.
Syntax: While Loop
The general structure of while loop is given below.
While condition [expression or statements] Wend
The condition is very important in
while loop because that is what decides when the loop will be terminated.
Consider the example below.
Dim index As Integer index = -1; While index < 10 MsgBox (index + 2) Wend
In the example above, we have put a condition for
while loop that the loop should continue unti
l index variable is equal to or greater than 10.
Dim Sum As Integer, i As Integer i = 0; While i < 10 Sum = Sum + i i = i + i Wend MsgBox ("The Value of Sum is " + Sum)
Output – While Loop
The program loop through and add the value of
i to Sum which is incremented by
1 at each iteration.
