| bool | Whether the last execution of the handler finished with the exception. |
Sample code
Suppose you have the following class definition.

| 4: | endmethod |
| 5: | endclass |
Usage of the IsError getter is as follows.
| 1: | handle h = new handle(); |
| 2: | timer tim = new timer(h,"THandler(dictionary)", 1000); |
| 3: | tim.StopWithException = false; // Non-stop timer handler. |
| 4: | tim.ShowException = false; // No error message dialog. |
| 5: | tim.Start(); // Start timer handler. |
| 6: | sleep slp. |
| 7: | slp.Freeze(10000); // It wait 10sec, the handler will be called and an exception will be thrown. |
| 8: | bool occur = tim.IsError; // It returns true because the handler will throw exception. |
Notes
Returns true if the last execution of the handler finished with the exception. Otherwise, returns false.
