Solved: Issue with Excel VB.net Code – Find Function Not Triggering TryCatch

Troubleshooting Question

I’m encountering an issue in my VB.net Excel Add-in. Specifically, I’m attempting to search for a value within a worksheet. I’ve implemented a Try…Catch block to handle any potential errors, but I’m facing a problem. It seems that even though I have error handling in place, the code is not moving to the Catch part as expected. Instead, it appears to be getting stuck at the Find function, which is depicted in the image I’ve provided.

What Could Be Causing This Behavior?

This situation raises the question: why is the Try…Catch block not functioning as intended, and why is it not capturing the error when the Find function encounters a problem?

In this scenario, it’s essential to explore potential reasons behind this behavior and determine how to resolve it effectively. By addressing this issue, we can ensure that error handling in the Excel VB.net code functions as expected, leading to a smoother and more reliable experience within the Excel Add-in.

Troubleshooting Compiler Breaks for Exception Handling in Your Code

When your code encounters a specific type of exception and the compiler seems to halt, it could be pausing just before reaching the Catch block. To investigate and address this issue, you have a couple of options:

Option 1: Set a Breakpoint and Resume Execution

Step 1: Place a breakpoint at the line in your code where the exception occurs (in this case, at the “M=” line).

Step 2: Hit the “F5” key or use your IDE’s “Run” command to continue the code execution.

Step 3: Observe if the breakpoint at the problematic line is hit during runtime. This will help you understand why the code isn’t proceeding to the Catch block.

Option 2: Adjust Exception Settings

Step 1: In your development environment, locate the “Exception Settings.”

Step 2: Find the checkbox labeled “Break when this exception type is thrown.”

Step 3: Uncheck this box for the specific exception type that’s causing the problem.

Step 4: Retry running your code to see if it now proceeds without breaking at that point.

By following these steps, you can investigate and potentially resolve the issue where your code is halting when it encounters a specific exception type, ensuring smoother exception handling in your development process.
