mscrm4ever: CRM 4.0 Multi Lingual Support in Plug-ins

==============

The following code presents a simple yet very effective way to handle and return multi-lingual error messages form a plug-in.

So how does it work?

Basically I created a base class for Custom Exceptions. All custom exceptions that you use in your code derive from this class. The base class overrides the Exception class Message property and returns the error message from a resources dictionary.

The resource dictionary holds the translations for each local id e.g. (1033, 3082). When an exception is thrown the user local id (LCID) is taken from the current running thread Culture Info object.

The Inner translation dictionary manages the each error message depending on the exception type. This way when the code throws a specific exception the correct error message is fetched from the dictionary.

Enjoy…
