Problem

You'd like a sample showing how verifiers can be defined in a configuration file, or the resource file used for validation error messages.

Solution

The download includes the following:

1. An app.config showing the <verifiers> section of the ideablade.configuration with a few verifiers defined.  If you define verifiers in a configuration file you must call DiscoverVerifiersFromConfig to load the verifiers.
   

   C#	var manager = new NorthwindIBEntityManager(); manager.VerifierEngine.DiscoverVerifiersFromConfig();
   VB	Dim manager = New NorthwindIBEntityManager() manager.VerifierEngine.DiscoverVerifiersFromConfig()

2. The VerifierErrorsResource.resx file used by DevForce validation.  You can modify this resource file to localize or modify the standard validation error messages.  Set the ErrorsResourceManager to your custom resource file:
   

   C#	var manager = new NorthwindIBEntityManager(); manager.VerifierEngine.ErrorsResourceManager = MyErrorMessages.ResourceManager;
   VB	Dim manager = New NorthwindIBEntityManager() manager.VerifierEngine.ErrorsResourceManager = MyErrorMessages.ResourceManager

   
   If you set the ErrorsResourceManager, the DevForce-supplied VerifierErrorsResource file is used as a fallback.
