Otherwise, you will end up with an endless loop that runs forever. Much like the situation with a Do.Loop without a condition, you should be sure that the code inside your While and Do loops eventually causes the condition to be satisfied. The example below shows two loops one testing the condition at the beginning and the other testing it at the end: Do loops provide more flexibility than While loops because they allow you to test the condition at the beginning or end of the loop. While loops on the other hand execute as long as the condition remains True. Do loops continue to execute all lines of code between the Do and Loop statements until a particular condition is True.

The Do.Loop is similar to the While loop but a bit more flexible. If the variable i was not less than ten in the first place, the contents fo the loop are skipped entirely and execution would continue at the line of code after the Wend statement. This continues until the condition is no longer True. The variable i is incremented by one and the loop returns to the top where the While statement checks to see if the condition is still True and if it is, then the code inside the loop executes again. Because zero is less than ten, execution will move inside the While.Wend loop. The variable “i” will be zero by default when it is created by the Var statement. The code between these statements is executed repeatedly, provided that the condition passed to the While statement continues to evaluate to True. If you need to use the variable after the loop executes, define it outside the loop, so that it is local to the method.Ī While.Wend loop executes one or more lines of code between the While and the Wend statements. It goes out of scope after the condition of the loop is satisfied. When you define a local variable inside a loop structure, its scope is local to the structure itself, not the entire method. You can declare local variables inside a loop structure. For.Each: The loop runs repeatedly for each element in an array.A local counter variable controls the execution of the loop. For.Next: The loop runs a specified number of times given in the For statement.Do.Loop: The loop runs until the condition specified in the Do or Loop statements are satisfied.

While.Wend: The loop runs until the condition specified in the While statement is satisfied.The following types of loop structures are available: Loops execute one or more lines of code over and over again.

How do you solve this problem? The answer is a loop. But suppose you need it to count fifty times or perhaps until a certain condition is met? Simply repeating the code over and over in these cases will either be just tedious or not possible.
