Call an external procedure from a class

[lstephane]

Hi,

I have a form with some sub-procedures including my errors handling.

Now, I need to call my error handling sub procedure from a class but can't remember how to call a sub-procedure of a form from a class.

Anybody can help me on this ?

Thanks !

FirstAidMan,

It may not be as simple as this but I exepect you would have to make the sub procedure in your form public and then call it using MyForm.MyProcedure.

It's kind of a backwards way of doing it. Your form should be using the class, the class should not be aware of what methods are on the form.

A better design would be to have an ErrorOccurred event in the class, and the form listens for the event (by using the WithEvents keyword when declaring the object). When the class detects an error, it raises the ErrorOccurred event (possibly passing a description as a parameter - or you might make a separate LastError property in the class that the form can read). In the Object_ErrorOccurred procedure on the form, it could pass the error up to your central error handler.
