Remarks

Use the Certificate property of the Signature object to return a Certificate object.

This type or member can be accessed only from code running in forms opened in Microsoft InfoPath Filler.

Examples

In the following example, the Status property of the Certificate class is used to determine the status and other information about the digital certificate used for the first signature on the first set of signed data (or for the entire form, if the entire form is configured to be signed), and display that information in a message box.

public void CertificateStatusAlert()
{
    Certificate myCertificate = 
       this.SignedDataBlocks[0].Signatures[0].Certificate;
    MessageBox.Show("IssuedTo: " + myCertificate.IssuedTo + 
        "\nIssuedBy: " + myCertificate.IssuedBy + 
        "\nExpirationDate: " + myCertificate.ExpirationDate + 
        "\nStatus: " + myCertificate.Status.ToString());
}

Imports Microsoft.VisualBasic.ControlChars
Public Sub CertificateStatusAlert()
    Dim myCertificate As Certificate = _
       Me.SignedDataBlocks(0).Signatures(0).Certificate
    MessageBox.Show("IssuedTo: " & myCertificate.IssuedTo & _
        NewLine & "IssuedBy: " & myCertificate.IssuedBy & _
        NewLine & "ExpirationDate: " & myCertificate.ExpirationDate & _
        NewLine & "Status: " + myCertificate.Status.ToString())
End Sub
