[Warning: Form must be shown after is created: MainForm]

Hi

 

I´m trying to develop a login form form a sample project

After i click the "Ok" button in the login form, i receive this message:

 

Warning: Form must be shown after is created: MainForm

 

the Ok button code is:

 

 

 

procedure TformLogin.UniButton1Click(Sender: TObject);

var

   LoginString : string;

begin

     LoginString := 'SELECT * FROM tbluser ';

     LoginString := LoginString + 'WHERE login = ' + #39 + (edtLogin.Text) + #39;

     LoginString := LoginString + ' AND password = ' + #39 + (edtPassword.Text) + #39;

 

     MainForm.qryLogin.Close;

     MainForm.qryLogin.SQL.Clear;

     MainForm.qryLogin.SQL.Add(LoginString);

     MainForm.qryLogin.open;

 

     if not MainForm.qryLogin.IsEmpty then  // check if query is empty

     Begin

          if MainForm.qryLogin.FieldByName('status').AsString='0' then  // check the user status, user may be inactive (0-inactive, 1-active)

          begin

               showmessage('User inactive'); // inform the user status

               MainForm.Close;  // close the application

          end

          else

          begin

               ModalResult:=mrOK;

               Mainform.ShowModal();

               MainForm.UniStatusBar1.Panels[1].Text := 'User:' + formLogin.edtLogin.Text; // write user name in status bar

          end;

     end

     else

     begin

           showmessage('Login or password is not correct!');

           edtLogin.Text := '';

           edtPassword.text := '';

           edtLogin.SetFocus;

           ModalResult := mrNone;

     end;

end;

 

any suggestion on how to solve this error message would be fine

thanks

[undeclared identifier in screensize demo]

Hi

 

the undeclared identifier happens after this steps:

a) i open the demo screensize

included a new button

c) INCLUDED the new form in the USES section

d) the code is just the show command, so main form can call the second form

when i try to run happens the error undeclared identifier informing that the second unit is not declared!

 

any ideas?

thanks

Hi Emiliano

Best regards

notify about map events through AjaxEvent like zoom , click , markerclick and

get some object properties like Length , Area etc.
