VBA while loop

In VBA, loops are used to execute a set of statements repeatedly until a certain condition is met. The While loop is one of the most commonly used loops in VBA. The While loop will execute the statements inside the loop while the condition is true.

Syntax

The basic syntax for the While loop is as follows:

While condition
   'statements
Wend

The condition is a logical expression that returns either True or False. If the condition is True, then the statements inside the loop will be executed.

Example

Let's create a simple VBA code that uses a While loop to iterate through an array of integers and prints out the values that are less than 5:

Sub WhileLoopExample()
    Dim i As Integer
    Dim arr() As Integer
    
    arr = Array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
    
    i = 0
    While arr(i) < 5
        Debug.Print arr(i)
        i = i + 1
    Wend
End Sub

In this example, we declare a variable i and an array arr of integers. We assign values to the array and then use a While loop to iterate through the array until the value of arr(i) is greater than or equal to 5.

Conclusion

In conclusion, the While loop is a widely used loop in VBA that allows for repetitive execution of statements based on a specified condition. It is important to ensure that the condition is carefully defined to avoid infinite loop situations in the code.
