How to Properly Assign Values to Class Variables in VBA Excel

If you're working with VBA in Excel and encountered issues with class variables not being assigned their values correctly, you're not alone. Many new VBA users face similar challenges when their variables don't seem to be set as expected. In this post, we'll explore a common scenario and provide you with clear guidance on how to solve the problem.

Understanding the Problem

You may have a situation where you're trying to assign a value to a class-declared variable in your VBA code, but it doesn't seem to carry over when you need it. Here’s a specific example of such a case:

You have a class module with a declared variable (e.g., table).

Debugging shows that the variable contains the correct value initially, but it appears empty when accessed later.

Analyzing the Solution

Thanks to feedback from helpful community members, we discovered that the order of operations is crucial when working with class variables. To solve the problem, follow these steps:

1. Initialize the Class Instance

In your module, ensure that you create a new instance of the class and set it up properly before trying to assign values to its variables. Here’s how your module should look:

3. Understanding the Show Method

The key takeaway here is that you need to assign the value to the variable before calling the Show method of your form (or popup). This ensures that when the event associated with your form (like a button click) occurs, it can access the correctly assigned variable.

Conclusion

By following the outlined steps to properly assign values to class declared variables in VBA Excel, you can ensure that your variables retain their assigned values and your functions run smoothly. Always remember that the timing of your assignments is just as crucial as the syntax itself!
