We'll be doing a more formal writeup of this, but here are some notes to get anyone who is interested in this started:

Every verifier has a ErrorMessageInfo property which in turn has a ResourceName property. This name is automatically generated (and set) during code gen for attribute based verifiers. For example, note the �autogenerated� ErrorMessageResourceNames below.

[IbVal.StringLengthVerifier(MaxValue=15, IsRequired=false, ErrorMessageResourceName="Employee_Country")]

public string Country { � }

[IbVal.RequiredValueVerifier(ErrorMessageResourceName="OrderDetail_Quantity")]

public short Quantity { � }

The resource name can also be set programmatically for any verifier defined in code.

The VerifierEngine has an �ErrorResourceManager� property that can assigned to with a statement like the following

_verifierEngine.ErrorsResourceManager = MyErrorMessages.ResourceManager;

where �MyErrorMessages� is the name of the strongly typed �designer.cs� class generated by the .NET ResX editor. The VerifierEngine will look up each verifiers �ResourceName� in the registered ErrorsResourceManager in order to generate validation error descriptions.

Regarding localization of these messages, please see Microsoft�s documentation for more information on this topic.

The VerifierEngine has a fallback ResourceManager it uses for system default error messages. These resource names may be overridden in the programmatically specified ResourceManager. The fallback manager ResX is listed at the bottom of this post.

Most error messages contain substitution parameters. The meaning and order of these substitution parameters is defined by the type of verifier involved. For example:

{0} is required

{0} must be between {1} and {2} character(s)

By simply including {0} {1} and {2} in any message, you can easily determine what parameters are used for that verifier.
