Subj : Restore Application on TOP

Greetings,

I would like to have one instance of my application running.
When an instance is minimized or behind another application
(such as Windows Explorer), when I click again on the
executable, I would like the running instance to show on top of
all other applications.

I used the following method:

WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
 HANDLE hInstanceMutex = ::CreateMutex(NULL,TRUE, "ENZO.MUTEX");

 // If application already running
 if(GetLastError() == ERROR_ALREADY_EXISTS) {
        if(hInstanceMutex)  CloseHandle(hInstanceMutex);
        Application -> Title = "";
        HWND hPrevApp = ::FindWindow(NULL, "Project1");

        // Restore the application
        if(hPrevApp)
            PostMessage(hPrevApp, WM_SYSCOMMAND, SC_RESTORE, 0);

        return 0;
  }

  try
  {
       Application->Initialize();
       Application->CreateForm(__classid(TForm1),&Form1);
       Application->Run();
  }
  catch (Exception &exception)
  {
       Application->ShowException(&exception);
  }
  return 0;
}


This works fine when the application is minimize (it pops-up on top of all other applications). 
It does not work when it is BEHIND other applications (not minimized)!

Is there a way of putting my application ON TOP again? I tried also ShowWindow(hPrevApp, SW_RESTORE) without success.

Thanks in advance,
S.
