debugging classes

[WindAndWaves]

Hi Gurus

I noticed that when you have a class module without error handling, you can
not actually debug it. That is to say, you will get an error when calling
the class, but it does not tell you where the error takes place. This is
especially difficult if you have several stacks within the class itself.

Here is what I do

1. create new instance of class
2. "let" some values in class
3. call a procedure in the class (open report)
4. this public sub, open report, calls several functions in the class itself
(private functions).

I get an error at 3, but I can not work out exactly where at 4 the error
occurs. Is there a way to work this out?

When debugging, in the VB Editor, go to Tools -> Options, and somewhere in
there, you'll find 3 error handling options. The default option is to break
on unhandled errors, but there are 2 other options, Break in Class Module, and
Break on All Errors. If you select either of those other 2 options, the code
will stop on the line that has your error and ignore the active error handling
in the calling code. Remember to set that back to the default later.

A Guess (since I use error trapping, never ran into this problem)
From code window, Tools->Options->General->Break in Class Module.

But you should error trap the code anyway.

You can change the options for error handling to Break in Class module but
you should be error trapping in the class module anyway. If you want the
error to propagate to the calling code then you should do this explicitly
using err.raise.
