how to hide a form when you are in a different method

hi..

I have the following question. How can I hide a form ? when while i'm not in form itself?? I go from my form to my BusinessLocig to my DataAccesLayer. I want to hide the form in the dataAccessLayer because there it checked if the user is logged in. However when I use Login(form name).Hide() it doesn;t hide.

here is my code"

// method on form login
private void login_button_Click(object sender, EventArgs e)
{
var organisationId = Convert.ToInt32(organissationlabel.Text);
string connectionString;
Password.Text = Encrypt(Password.Text);
using (var connection = DatabaseLayer.OpenConnection())
connectionString = ConnectionstringBusinessLogic.GetConnectionStringByOrgid(connection, null, Convert.ToInt32(organissationlabel.Text));
using (var connection = DatabaseLayer.OpenSecondConnection(connectionString))
using (var transaction = connection.BeginTransaction())
{
var userAmmountByOrgId = UserBusinessLogic.GetUserAmmountByOrgId(connection, transaction, organisationId);
var userAmmountContract = UserBusinessLogic.GetAllowedUsersByOrgId(connection, transaction, organisationId);
if (userAmmountByOrgId >= userAmmountContract)
label2.Visible = false;
UserBusinessLogic.UserLogin(connection, transaction, Username.Text, Password.Text, organisationId, connectionString);
transaction.Commit();
Hide(); // hier moet nog naar gekeken worden
}
}
1. public static void UserLogin(SqlConnection connection, SqlTransaction transaction, string username, string password, int organisationId, string connectionString)
2. {
3. UserDal.UserLogin(connection, transaction, username, password, organisationId, connectionString);
4. }
6. public static void UserLogin(SqlConnection connection, SqlTransaction transaction, string username, string password, int organisationId, string connectionString)
7. {
8. if (!username.Equals("") | !password.Equals(""))
9. {
10. try
11. {
12. using (var command = connection.CreateCommand())
13. {
14. command.Transaction = transaction;
15. command.CommandText = "SELECT * FROM Employes WHERE Username=@Username and Password=@Password and OrgId=@OrgId";
16. command.Parameters.Add("@Username", SqlDbType.NVarChar).Value = username;
17. command.Parameters.Add("@Password", SqlDbType.NVarChar).Value = password;
18. command.Parameters.Add("@OrgId", SqlDbType.Int).Value = organisationId;
19. using (var reader = command.ExecuteReader())
20. {
21. if (reader.Read())
22. {
23. MessageBox.Show(Resources.Login_login_button_Click_Login_Successful);;
24. var form = new Form1(connectionString);
25. form.Show();
26. // the hiding should take place here but how ?? login.hide doesn't hide
27. }
28. else
29. MessageBox.Show(Resources.Login_login_button_Click_Invalid_Credentials__Please_Re_Enter);
30. }
31. }
32. }
33. catch (Exception ex)
34. {
35. MessageBox.Show(ex.Message);
36. }
37. }
38. }

well the thing you suggested didn't quite work, but I fixed itusing a function to return a tulpe. so now now I can check and hide it when the conditions are true but thanks anyway

I would suggest you to look at this sample, if you have access for the forms,
privatevoidbutton1_Click_1(objectsender,EventArgse)
{
if(richTextBox1.Text!=null)
{
this.Visible=false;
Form2form2=newForm2();
form2.show();
}
elseMessageBox.Show("InsertAttributesFirst!");
}
