Examples

In the following example, created by adding the OnSign event to the form by selecting Programming from the Tools menu in the InfoPath designer user interface, a digital signature is added to the form by using the Sign() method of the SignatureObject object:

public void <span class="label">OnSign</span>(SignEvent e)
{
// The OnSign handler can be customized only in fully trusted form templates.
Signature thisSignature = e.SignedDataBlock.Signatures.Create();

// You can add other pieces of information to sign by modifying the signature
// template in thisSignature.SignatureBlockXmlNode.
thisSignature.Sign();
e.ReturnStatus = true;
}

// You can add other pieces of information to sign by modifying the signature

thisSignature.Sign();
e.ReturnStatus = true;
}

Remarks

You can use the OnSign event to add additional data to the digital signature. For example, you can add data from a trusted timestamp server, or add a server-side countersignature of the transaction. You can also use the OnSign event to block signing if the current user is not a member of a particular group.
