Introduction: The Challenge of Error Handling in Excel VBA

Excel spreadsheets are powerful tools, but they can also be sources of confusion, especially when dealing with errors. If you’re writing VBA code to find specific error messages (like -VALUE!, -N/A, and -REF!), it's crucial to ensure that your script not only identifies these errors but also responds appropriately. So, how can you create a VBA subroutine that alerts you when these errors occur and prevents subsequent operations if they are found?

In this guide, we’ll explore a solution to this exact problem. You’ll learn how to check for multiple error strings, display a message box when found, and call another sub if no errors are detected.

Understanding the Problem: What You Need to Fix

In the original code provided, the main issue was that even if the error strings were found, the subroutine continued to execute, leading to unwanted behavior. The goal was to halt the execution of certain actions unless no errors were found in the worksheet.

The Initial Code

Here’s a brief look at the code that needed to be improved:

The Solution: Revised Code Structure

To resolve the issues in the original code, we need to introduce a boolean variable that keeps track of whether any errors were found. Here's an updated version of the code:

Key Changes Made to the Code

Boolean Flag: Introduced blnCheckErrors to track if any errors were found during the search.

Conditional Execution: After the loop, checked the boolean flag to decide whether to execute zwrot2. This ensures that zwrot2 is only called if no errors were found.

Optimized Worksheet Reference: Used .Cells with the With statement to avoid redundant worksheet references.

Conclusion: Efficient Error Handling in VBA

By incorporating these improvements, your VBA code will not only search for error messages effectively but will also respond appropriately based on the results of that search. This results in a cleaner, more reliable subroutine that enhances the overall functionality of your Excel applications.

Feel free to implement this code in your projects, and modify it further based on your specific needs! Happy coding!
