Timer.Change Method (UInt32, UInt32)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Changes the start time and the interval between method invocations for a timer, using 32-bit unsigned integers to measure time intervals.
Assembly: mscorlib (in mscorlib.dll)
'Declaration <CLSCompliantAttribute(False)> _ Public Function Change ( _ dueTime As UInteger, _ period As UInteger _ ) As Boolean
Parameters
- dueTime
- Type: System.UInt32
The amount of time to delay before the invoking the callback method that was specified when the Timer was constructed, in milliseconds. Specify UInt32.MaxValue to prevent the timer from restarting. Specify 0 (zero) to restart the timer immediately.
- period
- Type: System.UInt32
The time interval between invocations of the callback method that was specified when the Timer was constructed, in milliseconds. Specify UInt32.MaxValue to disable periodic signaling.
| Exception | Condition |
|---|---|
| ObjectDisposedException | The Timer has already been disposed. |
The callback method is invoked once after dueTime elapses, and thereafter each time the time interval specified by period elapses.
If dueTime is 0 (zero), the callback method is invoked immediately. If dueTime is UInt32.MaxValue, the callback method is never invoked; the timer is disabled but can be re-enabled by calling Change and specifying a positive value for dueTime.
If period is 0 (zero) or UInt32.MaxValue, and dueTime is not UInt32.MaxValue, the callback method is invoked once; the periodic behavior of the timer is disabled but can be re-enabled by calling Change and specifying a positive value for period.
