Time must be egual to data system

Question

Hi,

 

I have on my form a Timer1, Label1 and Label2.

 

Then on my OnLoad Event I put:

Timer1.Start();
conn = new SqlConnection("Data Source = (LocalDB)\\MSSQLLocalDB; AttachDbFilename=C:\\myFolder\\App_Datas\\DB.mdf;Integrated Security = True;Integrated Security = True");
conn.Open();
string commandString = "select top 1 * from operation where S='" + "S" + "' order by nord desc";
SqlCommand comm = new SqlCommand(commandString, conn);
SqlDataReader read = comm.ExecuteReader();
if (read.HasRows)
{
while (read.Read())
{
Label1.Text = read["time"].ToString();
}
}
else
{
}
read.Close();
conn.Close();
if Label1.Text = DateTime.Now.ToString()
Label2.txt = "Yes";

On my timer_Click I put this:

Label1.Text = DateTime.Now.ToString("HH:mm");

What I need?

 

When the time its equal to the date system its should display on Label2 the word "yes". Otherwise its cant activate the second Label2.
