Answer 1

I studied Background worker and i do it this way I put execution of my procedure on another thread and progress bar in GUI thread

 BackgroundWorker bg = new BackgroundWorker();
 Boolean stopwork = true;
 Private void btnYes_Click(object sender, EventArgs e)
        {
            if (DialogResult.Yes == MessageBox.Show(clsGlobalObjectRefrances.OMessageString.SureWant2UpdateMarks, "", MessageBoxButtons.YesNo))
            {
                try
                {

                    bg.DoWork += bg_DoWork;
                    bg.RunWorkerCompleted += bg_RunWorkerCompleted;
                    bg.RunWorkerAsync();
                    pgbUpdateMarks.Maximum = 60;
                    Stopwatch st = new Stopwatch();
                    st.Start();
                    while(stopwork)
                    {
                        pgbUpdateMarks.Value = st.Elapsed.Seconds;
                    }
                    pgbUpdateMarks.Value = 0;
                    MessageBox.Show("Executed sucessfully");
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message);
                }
            }
        }

Where DoWork is

 void bg_DoWork(object sender, DoWorkEventArgs e)
        {

        dbDataEntities db = new dbDataEntities();
        string myquery = "DECLARE @return_value int EXEC    @return_value = [dbo].[ssspUpdateMarksOfStudent] SELECT 'Return Value' = @return_value";
        db.Database.ExecuteSqlCommand("myquery");
        stopwork = false;
        }
