SignatureProvider.GetProviderDetail method (Office)

  • Article

Queries the signature provider add-in for various details.

Syntax

expression.GetProviderDetail(sigprovdet)

expression An expression that returns a SignatureProvider object.

Parameters

Name Required/Optional Data type Description
sigprovdet Required SignatureProviderDetail Contains an enumerated value representing the type of information to query the add-in for.

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; 
 } 
 }

Note

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