## Timer::Change(int64_t, int64_t) method

```cpp
bool System::Threading::Timer::Change(int64_t dueTime, int64_t period)
```


| Parameter | Type | Description |
| --- | --- | --- |
| dueTime | int64_t | [Timeout](../../timeout/) before next invocation of callback function, in milliseconds; negative values cancel timer even if it was scheduled. |
