[Visual Basic]
Public ReadOnly Property ValidDate As Boolean[C#]
public bool ValidDate {get;}[C++]
public: __property bool get_ValidDate();A boolean indicating whether or not the certificate has a valid date.
If the current date-time is greater than Certificate.IssueDate and less than Certificate.ExpirationDate, this property will return true. Otherwise, this property will return false indicating an invalid date.
The following example demonstrates creating a simple secure client.
[Visual Basic]
Private Sub CertificateReceived(ByVal sender As Object, ByRef e As CertificateReceivedEventArgs) Handles Tcp1.CertificateReceived
Dim msg As String = "The certificate was invalid for the following reason(s)" + vbCrLf
' Check to see if the certificate is from a trusted root.
If Not e.TrustedRoot Then
msg += "This certificate is not from a trusted root" + vbCrLf
End If
' Check to see if the certificate has a valid date.
If Not e.ValidDate Then
msg += "This certificate does not have a valid date" + vbCrLf
End If
' Check to see if the certificate has a valid name.
If Not e.ValidName Then
msg += "This certificate does not have a valid name" + vbCrLf
End If
If msg <> "" Then
msg += "Would you like to accept this certificate anyway?"
If MessageBox.Show(msg, "Invalid Cert Received", MessageBoxButtons.YesNo) = DialogResult.Yes Then
e.Accept = True
End If
End If
End Sub
[C#]
private void CertificateReceived(object sender, CertificateReceivedEventArgs e)
{
string msg = "The certificate was invalid for the following
reason(s)\n";
// Check to see if the certificate is from a trusted root.
if(!e.TrustedRoot)
msg+= "This certificate is not from a trusted root\n";
// Check to see if the certificate has a valid date.
if(!e.ValidDate)
msg+= "This certificate does not have a valid date\n";
// Check to see if the certificate has a valid name.
if(!e.ValidName)
msg+= "This certificate does not have a valid name\n";
if(!e.Accept)
{
msg += "Would you like to accept this certificate anyway?";
if(MessageBox.Show(msg, "Invalid Cert
Received", MessageBoxButtons.YesNo) == DialogResult.Yes)
e.Accept = true;
}
