Enabling a button from another form and closing the form...
===

I have Form1 and Form2
 
Form1 I have a button that is disabled, but if I click on the menustrip on Form1 I go to Form2. On Form2 I log into a database. After I logged in successfully, I want Form2 to close and I want the button on Form1 to be enabled.
 

Here is my code:
 
                        



         private void button1_Click(object sender, EventArgs e)
 
        {
 
           

            

                     SqlConnection connection = new SqlConnection(@"Data Source=VS124ITM;Initial Catalog=KnowledgeEssentials;Integrated Security=True");
 
            

                     SqlCommand command = new SqlCommand("SELECT * FROM UserT WHERE UserName ='" + textBox1.Text + "' AND password ='" + textBox2.Text + "'", connection);
 
                     connection.Open();
 
            

                     SqlDataReader reader = null;
 
                     reader = command.ExecuteReader();
 
            

                     if (reader.Read())
 
                       {
 
                

                           MessageBox.Show("Welcome " + reader["UserName"].ToString());
 
                           Form1 lfm = new Form1();
 
                          lfm.button1.Enabled = 

true;
 
                    

                                  Form2 fm = new Form2();
 
                                  fm.Close();
 
                

                                      }
 
            

                                     else
 

                                       {
 
                

                               MessageBox.Show("Username and password " + textBox1.Text + "does not exist");
 
                                          }
 
            


 

        }
