JLI Spieleprogrammierung

Ich hätte da mal ne Frage.
Was passiert, wenn ich einen Timer mit SetTimer() erstell und dann unglücklicherweise einen 2 mit der selben ID erstell? Wird der 1. "gekillt", oder lässt sich der 2. gar nicht initalisieren?
Oder laufen beide Parallel, so dass doppelt soviele Timeouts eintretten?

Und was passiert, wenn ich KillTimer verwende, ohne einen Timer gesetzt zu haben? Ist das, wie wenn man auf nicht reservierten Speicher zugreift??

Ich danke für Antworten

Schauen wir mal was die MSDN dazu sagt:
Parameters

hWnd
[in] Handle to the window to be associated with the timer. This window must be owned by the calling thread. If this parameter is NULL, no window is associated with the timer and the nIDEvent parameter is ignored.
nIDEvent
[in] Specifies a nonzero timer identifier. If the hWnd parameter is NULL, this parameter is ignored. If the hWnd parameter is not NULL and the window specified by hWnd already has a timer with the value nIDEvent, then the existing timer is replaced by the new timer. When SetTimer replaces a timer, the timer is reset. Therefore, a message will be sent after the current time-out value elapses, but the previously set time-out value is ignored.
uElapse
[in] Specifies the time-out value, in milliseconds.
Windows NT/2000/XP: If uElapse is greater than USER_TIMER_MAXIMUM, the timeout is set to 1.

Windows 2000/XP: If uElapse is less than USER_TIMER_MINIMUM, the timeout is set to USER_TIMER_MINIMUM.

Windows Server 2003: If uElapse is greater than USER_TIMER_MAXIMUM, the timeout is set to USER_TIMER_MAXIMUM.

Windows XP SP2/Windows Server 2003 SP1: If uElapse is less than USER_TIMER_MINIMUM, the timeout is set to USER_TIMER_MINIMUM. If uElapse is greater than USER_TIMER_MAXIMUM, the timeout is set to USER_TIMER_MAXIMUM.

lpTimerFunc
[in] Pointer to the function to be notified when the time-out value elapses. For more information about the function, see TimerProc. If lpTimerFunc is NULL, the system posts a WM_TIMER message to the application queue. The hwnd member of the message's MSG structure contains the value of the hWnd parameter.


und:

An application can process WM_TIMER messages by including a WM_TIMER case statement in the window procedure or by specifying a TimerProc callback function when creating the timer. When you specify a TimerProc callback function, the default window procedure calls the callback function when it processes WM_TIMER. Therefore, you need to dispatch messages in the calling thread, even when you use TimerProc instead of processing WM_TIMER.

The wParam parameter of the WM_TIMER message contains the value of the nIDEvent parameter.

The timer identifier, nIDEvent, is specific to the associated window. Another window can have its own timer which has the same identifier as a timer owned by another window. The timers are distinct.

SetTimer can reuse timer IDs in the case where hWnd is NULL.

und was ist wenn man kein Englisch kann? (ich mein wenn man schon in Anbetracht zieht, dass blinde Leute ... ich lass es mal lieber)

@ Threadersteller
Falls das je passieren sollte, wird der alte Timer durch den neuen erstetzt. Verschiedene Fenster können je einen Timer mit gleicher ID haben. Um das einfach mal dem von unsigned geposteten Artikel zu entnehmen...
