How do I get the function/procedure name when an error occurs?

Zones: Microsoft Visual Basic.Net, Visual Studio .NET 2005, .NET Framework 3.x versions

Tags: VB.NET, VS 2005, .NET version 3.0

I am trying to create a procedure that when called will write to a log file the following:

Exception message, name of the procedure or function in which the error occured and the system time
Maybe even the users AD ID, but I just thought of that while I was typing. :)

I have pasted the code I have to write to the log file, I'm just not sure how to get the name of the procedure/function object.

I tried creating an exception and then looking through that, but I didn't see the name of the function object anywhere. I also tried looking at what was under ME. while in debug and it might even be in there somewhere, but I didn't see it. I know I can show what form the error occured in, but I would like to get something like APP Name.form Name.procedure name.

Thanks,

I imagine you could parse those from the first line of Exception.StackTrace

rgn2121:

I will check that, but I created exceptions and debugged and read through the stack trace...I never saw the name of the current procedure.

rgn2121:

I looked through it, but didn't see the name of the current procedure.

Okay...looks like it is the very last few lines of the stack trace. I am not sure how to get that info in a veriable though. I would like to have the frmFORM_NAME.readOracleInfo from the snippet below, but I am not sure how to get that no matter where is my app it happens.

I think string has methods that let you find the last index position of a character within a string. You could use that to find the last newline character. Then extract the string from that position to the end. Then get the index of the first period and the first (, and extract the string between those positions. That would be what you are looking for. Or maybe start by doing a split on "at " and work with the last element of the returned array.
