This is particularly usefull for applications when a phisical detach would be expected.</p><p>Remember that many of the methods, if called on an unattached device, will throw a PhidgetException. This Exception can be checked to see if it was caused by a device being unattached, but a better method would be to regiter the detach handler, which could notify the main program logic that the device is no longer available, disable GUI controls, etc.</p><p>There is no limit on the number of detach handlers that can be registered for a particular Phidget.</p></div></div><p><div id="footer"> </div>Assembly: Phidget21.NET (Module: Phidget21.NET) Version: 2.1.3.23</p></div></body></html>?? 快捷鍵說明
