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 OnSign(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.<span class="label">Sign</span>();
e.ReturnStatus = true;
}
Remarks
The Sign method can only be called from the OnSign event. Calling this method advances the Digital Signatures Wizard to the second step in the signing process, selecting a certificate.
