SetTimer Function call ...

Is there someone out there who can give me an example of the CListBox.SetTimer(), CListBox.OnTimer() and CListBox.KillTimer()?

What exactly are you trying to do?  The CListBox does not have a timer function of its own that I am aware of.  I can help you write a Timer if you will tell me what you want to do with it... with respect to the CListBox.

These are members of CWnd, the base class of CListBox (and a lot of other classes too, such as CView).

Look for examples of CWnd::SetTimer

Typically, the timer is set within the controlling window's message loop and not within the control itself.  Then on the OnTimer, you will update the list box accordingly.  Otherwise, you'll will have to override the CListBox with a class of your own.

I want to create some kind of buffer. When a user presses a key then a stringbuffer is created related to a timer. That buffer stays active for 1sec and is destroyed again unless the user pressed a key within that 1sec. The the timer is restarted again.

Alright, here's some pseudo-code.  I call it pseudo code in case I make a mistake :)

#define ID_TIMER_ON_CHAR  WM_USER + 102

CMyListBox::OnChar( )
{
.
   SetTimer( ID_TIMER_ON_CHAR, 1000, NULL );
}

// Override the WM_TIMER

void CMyListBox::OnTimer( UINT uiEvent )
{
   if( uiEvent == ID_TIMER_ON_CHAR )
   {
   // do what you want here!
      KillTimer( ID_TIMER_ON_CHAR );
   }

   CListBox::OnTimer( uiEvent );
   return;
}
