Get length of array?

Getting the Length of an Array: Explained and Solved! 📏

So, you want to get the length of an array but keep encountering the dreaded "Object required" error? Fear not! In this blog post, we will dive into the common issues surrounding this problem and provide you with easy-to-follow solutions. By the end, you'll be armed with the knowledge to conquer this error and retrieve the length of your arrays effortlessly! 💪

Understanding the Error 🛠️

The "Object required" error message occurs when you try to access a property or method that requires an object, but you haven't assigned a valid object reference. In this case, the array's Length property is being accessed incorrectly, triggering the error.

The Solution: a Simple Syntax Correction ✅

To obtain the length of an array in VBA, you need to use a different property called "UBound," which stands for "upper bound." This property returns the highest available subscript for a particular array dimension.

In the provided example, instead of using "columns.Length," you should use "UBound(columns) + 1" to retrieve the length of the array. Let's update the code snippet accordingly:

Dim columns As Variant
columns = Array( _
"A", "ID", _
"D", "Name")
Debug.Print UBound(columns) + 1

By making this small syntax correction, you will successfully retrieve the length of your array without encountering the "Object required" error.

Example: Understanding the Updated Code 🔍

To help you grasp the solution conceptually, let's break down what happens in our updated code using the provided example:

1. Array Initialization: The columns variable is assigned an array value using the Array() function. In this case, the array contains four elements: "A," "ID," "D," and "Name."

2. Retrieving Length: We use the UBound(columns) function to determine the highest subscript (index) in the columns array. Since arrays in VBA are zero-based, the highest subscript will be one less than the length of the array. To get the actual length, we add 1 to the result using the + 1 syntax.

3. Printing the Result: Finally, we use Debug.Print to display the length of the array in the Immediate window. This way, you can easily verify that the length is correctly obtained.
