Active Directory - check if password never expires?

Question

Is there a way in Visual Basic to check if the user's password is set to never expire in Active Directory?

I've found a way to find the last date it was changed, but I can't find the other available options.

Dim de As DirectoryServices.DirectoryEntry = GetUser(uDetails.username)
Dim objUser = GetObject(de.Path)
If objUser.PasswordLastChanged < DateTime.Now.AddMonths(-3) Then
...

Where can I find a list of all available objUser properties?

Answer 1

public bool isPasswordExpired(String p_UserName, String p_DomainName)
{
    bool m_Check=false;

    int m_Val1 = (int)de1.Properties["userAccountControl"].Value;
    int m_Val2 = (int) 0x10000;

    if (Convert.ToBoolean(m_Val1 & m_Val2))
    {
        m_Check = true;
    } //end

    return m_Check
}
