On Error Goto ....

[MTSkull]

I notice in the error object we have an err.erl property, which the program tells me is the line where the error occurred. However when my program is running and calls this property it is always passing zeros. Is this an unimplemented feature or do I have to do something special to make it work?

Under .Net you really should be looking at using Exceptions rather than the on error goto method.

Use Try..Catch

Try
   'Code that can crash

Catch IOExc as IO.IOException
   Messagebox.Show("File Error: " & IOExc.Message)
Catch Exc as Exception
   Messagebox.Show("General Error: " & Exc.Message)
End Try

Yeah, avoid On Error Goto. Structured Exception Handling is the way to go.

 

To get the line number of the offending code, you can use the StackFrame class. There's a good sample from the 101 VB.NET Samples available from MS.

Thanks, I will look into that.
