//  The mailman object is used for receiving (POP3)
//  and sending (SMTP) email.
Chilkat.MailMan mailman = new Chilkat.MailMan();

//  Any string argument automatically begins the 30-day trial.
bool success;
success = mailman.UnlockComponent("30-day trial");
if (success != true) {
    MessageBox.Show("Component unlock failed");
    return;
}

//  Set the POP3 server's hostname
mailman.MailHost = "mail.chilkatsoft.com";

//  Set the POP3 login/password.
mailman.PopUsername = "matt@chilkatsoft.com";
mailman.PopPassword = "****";

Chilkat.StringArray sa;

sa = mailman.GetUidls();
int i;
int n;
n = sa.Count;

for (i = 0; i <= n - 1; i++) {
    textBox1.Text += sa.GetString(i) + "\r\n";
    textBox1.Refresh();
