Timer::Change Method (UInt32, UInt32)
Changes the start time and the interval between method invocations for a timer, using 32-bit unsigned integers to measure time intervals.
This API is not CLS-compliant.
Assembly: mscorlib (in mscorlib.dll)
public: [CLSCompliantAttribute(false)] bool Change( unsigned int dueTime, unsigned int period )
Parameters
- dueTime
-
Type:
System::UInt32
The amount of time to delay before the invoking the callback method specified when the Timer was constructed, in milliseconds. Specify Timeout::Infinite to prevent the timer from restarting. Specify zero (0) to restart the timer immediately.
- period
-
Type:
System::UInt32
The time interval between invocations of the callback method specified when the Timer was constructed, in milliseconds. Specify Timeout::Infinite 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 zero (0), the callback method is invoked immediately. If dueTime is Timeout::Infinite, 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 zero (0) or Timeout::Infinite, and dueTime is not Timeout::Infinite, 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.
The Change method can be called from the TimerCallback delegate.
