Egg like timer

Question

I am new vb.net user. I am attempting to create a timer which is started when a button is clicked and stopped when another button is clicked. The timer should be in the form of 00:00:00- hrs,mins,secs. The timer should be visually incrementing. I have no idea how to do this. This may be simple to someone else. I have no code as such but have spent 2 weeks looking for something on the internet with no luck. So can anybody please help me out?

Answer 1

For button Click you may refer following code:

 

 

 

 

bool blnFound = false;

SqlConnection sqlCon = null;

sqlCon = new SqlConnection(ConfigurationManager.AppSettings["con"].ToString());

sqlCon.Open();

SqlCommand cmd = new SqlCommand("select * from Users where", sqlCon);

SqlDataReader dr = cmd.ExecuteReader();

 while (dr.Read())

 {

   //validating user name

   if (dr["usr_vch_Name"].ToString() == cboUserName.Value)

         {

             // validating password

             if(dr["usr_vch_Password"].ToString()).ToString() == txtPassword.Text)

{

                   blnFound = true;

                // User validated successfully, code redirect to other pages

 

}

 

         }

 

 }
