Next construction runs a set of statements once for each element in a collection. For more information, see For.Next Statement. You specify the starting and ending values for this counter, and you can optionally specify the amount by which it increases from one repetition to the next. It uses a loop control variable, also called a counter, to keep track of the repetitions. Next construction performs the loop a set number of times. For more information, see Do.Loop Statement.
You can also specify whether to repeat the loop while the condition remains True or until it becomes True. Loop construction allows you to test a condition at either the beginning or the end of a loop structure.
For more information, see While.End While Statement. End While construction runs a set of statements as long as the condition specified in the While statement is True. The following illustration shows a loop structure that runs a set of statements until a condition becomes true: You can repeat the statements in a loop structure until a condition is True, until a condition is False, a specified number of times, or once for each element in a collection. Visual Basic loop structures allow you to run one or more lines of code repetitively.
