SignatureProvider.GetProviderDetail Method

Queries the signature provider add-in for various details.

Note
Signature providers are implemented exclusively in custom COM add-ins and cannot be implemented in Microsoft Visual Basic for Applications (VBA).

Syntax

expression.GetProviderDetail(sigprovdet)

expression An expression that returns a SignatureProvider object.

Parameters

Return Value
Variant

Remarks

The SignatureProvider object is used exclusively in custom signature provider add-ins. This method is used to query the add-in for three pieces of information:

• What hash algorithm does the add-in support?
• Is the add-in only a user interface (UI) or does it support hashing and verification? If TRUE is returned, Microsoft Office does not call the add-in to hash or verify, only to display the UI.
• What URL should the add-in provide for users if they are missing the signature add-in?

Example

The following example, written in C#, shows the implementation of the GetProviderDetail method in a custom signature provider project.

 public object GetProviderDetail(SignatureProviderDetail sigProvDetail) { switch (sigProvDetail) { case Microsoft.Office.Core.SignatureProviderDetail.sigprovdetHashAlgorithm: return this.HashAlgorithmIdentifier; case Microsoft.Office.Core.SignatureProviderDetail.sigprovdetUIOnly: return false; case Microsoft.Office.Core.SignatureProviderDetail.sigprovdetUrl: return this.ProviderUrl; default: return null; } }
