Delphi-Quellcode:

type
  PEnumInfo = ^TEnumInfo;
  TEnumInfo = record ProcessID: DWORD; HWND: THandle; end;

function EnumWindowsProc(Wnd: DWORD; var EI: TEnumInfo): Bool; stdcall;
    var
      PID: DWORD;
    begin
      GetWindowThreadProcessID(Wnd, @PID);
      Result := (PID <> EI.ProcessID) or (not IsWindowVisible(WND)) or (not IsWindowEnabled(WND));
      if not Result then EI.HWND := WND;
    end;

  function FindMainWindow(PID: DWORD): DWORD;
    var
      EI: TEnumInfo;
    begin
      EI.ProcessID := PID;
      EI.HWND := 0;
      EnumWindows(@EnumWindowsProc, Integer(@EI));
      Result := EI.HWND;
    end;
