Name of offending code

Hi, In an attempt to simplify the debugging process, I wrote a public sub EC (ErrorCatcher), that I can call from anywhere in my app, which writes all necessary information to a text file. Something like:
Public Sub EC(Byval err As Exception) dim line as string = Now & " - Error: " & Err.TargetSite.Name & " - " & Err.Message 'write line to file, etc. End Sub Private Sub MyCode() Try 'some error happens here Catch ex As Exception EC(ex) End Try End SubThisErr.TargetSite.Nameis just my latest attempt, but it does not tell me that the error took place in Private Sub MyCode. Is there any way (other than passing it to the EC sub as a handwritten string) at all to find out in what part of the code the exception occurred, at runtime, and if yes then how? Any help or suggestions appreciated. JohanMy advice is free, and you may get what you paid for.

Yes, you can get the stack trace from the exception object and print it, it will tell you what method threw the exception, and a call stack down from there.

Hi, rather than using Exception.Message and/or Exception.StackTrace you really should use Exception.ToString() it will show you at least the Message and the StackTrace but also: - additional information (e.g. the filepath on a File Not Found) - information about "inner exceptions" :)

Thanks Luc, I'll definitely give this a try.

Thanks Christian, Steve also suggested this, and according to Luc I can get even more information out of an exception by simply using Exception.ToString(). Thank all you guys, this really helps.
