How do I determine whether a virtual character is from a Sony Jog Dial or the Palm clock silkscreen button?
Ans :- There is an overlap in the virtual character values of the key events generated by the Sony Jog Dial hardware and the clock silk-screened button of specific Palm-branded handhelds running Palm OS 4.0. Specifically, the Palm m500 and m505 handhelds incorrectly generate a virtual key event, which was previously allocated for Sony’s use. Generally speaking, this problem does not affect most applications. However, there are two situations when developers may need to verify what generated the virtual character before using it. Applications that use the Sony SDK and make use of the Jog Dial When your application is running on an affected Palm handheld, the virtual key event generated by a tap on the clock silkscreen is handled within SysHandleEvent of the Event Loop by launching the clock application. SysHandleEvent then returns true. If your application handles Jog Dial events after SysHandleEvent in the Event Loop, such as within a form handler, it will not misread the clock virtual
