How do I find out what class called me

[Guest]

Hi,

I want to write an error handler for my project. I would call this handler
and have it print a message. What I'd like to be able to do is to have the
handler know which class called it. Also, since the class that called it may
have been passed bad data from another class, I'd like to pass the name of
the other class also (if applicable).

So, suppose Class A instantiates Class B. Can Class B know who Class A is
without Class A passing that information as a parameter?

I'd appreciate any suggestions or advice.

dim st as new stacktrace


Have a look at st.framecount and st.getframe and all the members of the
returned objects including the type information you get from them. See also
System.Reflection.MethodBase.GetCurrentMethod

I should add: When throwing an exception, you already have a stacktrace.

Wow, that's pretty badass. I am deeply impressed. I would never have
thought of that!

Armin,

Thanks very much for the help. This is a whole new area for me so it's
going to take some time to figure it all out.
