Difference between same database.

What's the connection string of 
DBConn_SI
& 
DBConn


Please paste code for DBConn_SI.drugInsert_SI &  DBConn.drugInsert

Sumit, i used one database in form which is called Items Avaliable and the other database in the form which is Items Sell both have same coloums.

yaa sure i paste my source code of form 1 and form 2 both.


thanks sumit for help :)

Source Code form 1 (Insert):

 private void btninsert_Click(object sender, EventArgs e)
        {
            if (txtparticular.Text.Length > 0 && txtquantity.Text.Length > 0)
            {
                int k = DBConn_SI.drugInsert_SI(txtparticular.Text, Int32.Parse(txtquantity.Text), Int32.Parse(txtrate.Text), DateTime.Parse(txtdatetime.Text));
                if (k > 0)
                {
                    dgvDrugs_SI.DataSource = DBConn_SI.getAllDrugs();
                }
                else
                {
                    MessageBox.Show("No record inserted");
                }
            }
            else
            {
                MessageBox.Show("Please fill in ID and Name of the drug");

            }

Source Code of form 2 (Insert):
private void btninsert_Click(object sender, EventArgs e)
   {
       if (txtparticu.Text.Length > 0 && txtquanti.Text.Length > 0)
       {
           int k = DBConn.drugInsert(txtparticu.Text, Int32.Parse(txtquanti.Text), Int32.Parse(txtrate.Text), DateTime.Parse(txtdatetime.Text));
           if (k > 0)
           {
               dgvDrugs.DataSource = DBConn.getAllDrugs();
           }
           else
           {
               MessageBox.Show("No record inserted");
           }
       }
       else
       {
           MessageBox.Show("Please fill in ID and Name of the drug");
       }
   }

First of all I would like to know the reason behind using two databases. Two forms and two dbs, what's the rationale behind it. 

Anyway, ideally it's not possible that query fired over 1 db inserts record into other db. It's very strange. Can you please paste code for any operation say Insert?
