void SetForegroundWindowInternal(HWND hWnd)
{
 if(!::IsWindow(hWnd)) return;

 //relation time of SetForegroundWindow lock
 DWORD lockTimeOut = 0;
 HWND  hCurrWnd = ::GetForegroundWindow();
 DWORD dwThisTID = ::GetCurrentThreadId(),
  dwCurrTID = ::GetWindowThreadProcessId(hCurrWnd,0);

 //we need to bypass some limitations from Microsoft :)
 if(dwThisTID != dwCurrTID)
 {
  ::AttachThreadInput(dwThisTID, dwCurrTID, TRUE);

  ::SystemParametersInfo(SPI_GETFOREGROUNDLOCKTIMEOUT,0,&lockTimeOut,0);
  ::SystemParametersInfo(SPI_SETFOREGROUNDLOCKTIMEOUT,0,0,SPIF_SENDWININICHANGE | SPIF_UPDATEINIFILE);

  ::AllowSetForegroundWindow(ASFW_ANY);
 }

 ::SetForegroundWindow(hWnd);

 if(dwThisTID != dwCurrTID)
 {
  ::SystemParametersInfo(SPI_SETFOREGROUNDLOCKTIMEOUT,0,(PVOID)lockTimeOut,SPIF_SENDWININICHANGE | SPIF_UPDATEINIFILE);
  ::AttachThreadInput(dwThisTID, dwCurrTID, FALSE);
 }
