Debugging can be easy or hard. It’s easy if you have an easily reproducible error. This morning I wrestled a bug where a screen just stopped showing data. Nothing. Zilch.
When I debugged through, I watched every piece of data get properly set to labels in my Winforms view that were visible, but the screen shows up without the data!! What gives?
Ultimately, I was looking at the wrong instance of my screen/view.
Here’s a debugging tip to use if you watch the code executing properly but it still doesn’t work in the end:
Make sure you are looking at the right object.
In the debugger, set a breakpoint in the constructor and ensure you are watching the right instance. In the immediate window, use the hashcode to track the instance:
This way, you can clearly identify the object.
