Im making an application that, initialy, it runs invisible. So, the property Form1.Visible is initialy False. But, when it starts, the application reads the procedure WndProc, and it turns that property to True. I tried to put an If structure at WndProc, like:
if a=0 then
  Form1.Visible := False
else
  Form1.Visible := True; ,
but, when i do that, the application doesn't appears anymore. What can i do and why the procedure WndProc is so unstable (it's readen more than 1000000 times at the start up).

Yo,
modify your project's source code like this:

begin
  Application.Initialize;
  Application.CreateForm(TForm1, Form1);
  Form1.Visible := false; // if not already set in object inspector
  Application.ShowMainForm := false;
  Application.Run;
end.
