Hello all

This question is strangely derived from this post.

I wanted to ask you how to set properly a timer. Three options:

Generally, you have to avoid situation where callback is invoked after target instance is destroyed.

Quote:

1. Inside a class derived from Ctrl
SetTimeCallback(time, THISBACK(callbackFunction));

In client code, use TimerCallback. TimerCallback destructor removes the callback from the timer queue if necessarry.

You can use SetTimeCallback directly, but then you have to rember id and remove in destructor.

Quote:

2. In a GUI program, in a class not derived from Ctrl

Use SetTimeCallback directly, but remember to remove callback from the queue as necessary.

Quote:

3. In a console program

You cannot. It is CtrlCore feature...
