How to get stack info programatically?

General
1

Hello,

I’m trying to debug some code in the field. I would like to add some code to a project so that whenever it pops out of a loop, I can have a record to show me what function it goes into and some properties I have built in.

Is there a way to do this? If so, how??

Thanks,
Tim

Check into the Runtime object.

You can use my ExceptionHandler for this. See Xojo + Alfred .

Hi Eric.

I don’t think that will do it. Something like CurrentMethodName that I can get from anywhere in the project.

@Beatrix_Willius - Thank you, I will look into your suggestion!

Hello Beatrix

The example for Alfred, did not come down as a project or anything that I can load into Xojo. I am using a Windows 11 machine, which may make a difference.

You can raise an exception whenever you want, just catch it and inspect the stack.

try
  raise new RuntimeException

catch ex as RuntimeException
  // ex.Stack

end try
