Hi, I'm working on an application where the form is ever hidden, the form
must appear only after the left mouse button is down for more than one or
two seconds with the cursor still. I this way the cursor is not on my active
form and the APIs don't work (GetMessage etc). Is there a function to that
allows  my application to listen the WM_LBUTTONDOWN message everywhere in
the system?
Code examples tested:

void __fastcall TForm1::Timer1Timer(TObject *Sender)
{
MSG msg;
GetMessage(&msg,NULL,0,0);
if(msg.message == WM_LBUTTONDOWN)

{
// It works only on the form (if  I don't hide it)
   Form1->Show();
   something to do;
  }
....
.....
.....
}

I tryed to add GetActiveWindow() but the application became very slow;

void __fastcall TForm1::Timer1Timer(TObject *Sender)
{
MSG msg;
HWND active_wnd = GetActiveWindow();
GetMessage(&msg,active_wnd,0,0);                                         //
This is very slow almost still
if(msg.message == WM_LBUTTONDOWN)
  {
   Form1->Show();
   something to do;
  }
....
.....
.....
}

 Many thanks in advance, Ferdinando Rizzi ferrizzi@libero.it
