Class	Description
bool	Whether the last execution of the handler finished with the exception.

Suppose you have the following class definition.

1:	class handle
2:	open method void LCHandler(dictionary dic)
3:	throw "exception"; // Exception occurs.
4:	endmethod
5:	endclass

Usage of the IsError getter is as follows.

1:	browser b = new browser();
2:	message m;
3:	handle h = new handle();
4:	switch sw = b.LoadCompleted(h,"LCHandler(dictionary)");
5:	sw.StopWithException = false; // Non-stop event handler.
6:	sw.ShowException = false; // No error message dialog.
7:	sw.Start(); // Start event handler.
8:	_br.LoadUrl("https://example.com/", true); // It is synchronously page loading.
9:	sleep slp.
10:	slp.Freeze(10000); // It wait 10sec, the handler will be called and an exception will be thrown.
11:	bool occur = sw.IsError; // It returns true because the handler will throw exception.

Returns true if the last execution of the handler finished with the exception. Otherwise, returns false.

None.
