I added a timer by overwriting OnTimer:

void CTestPhasePPMDlg::OnTimer(UINT_PTR nIDEvent)
{
CDialog::OnTimer(nIDEvent);
}

I can Set the timer with
SetTimer(1, 2000, NULL);

but how shall I kill the timer with
KillTimer(...);

if I do not know the variable of the timer?

CWnd::SetTimer returns an UINT_PTR, you can store this value e.g. as a
member variable of your dialog class, and pass that value to
KillTimer.

e.g.

  // Timer ID (member variable)
  UINT_PTR m_nTimer;

  // Set the timer
  m_nTimer = SetTimer(1, 2000, NULL);

  ...

  // Kill tht timer
  KillTimer( m_nTimer );
  m_nTimer = 0;

In addition.
If more than one timer, in handler's body, they should be identofied by
their ids;
void CTestPhasePPMDlg::OnTimer(UINT_PTR nIDEvent)
{
if (nIDEvent == m_nTimer1)
{
}
else if (nIDEvent == m_nTimer2)
{
}

CDialog::OnTimer(nIDEvent);
}
