Windows 8學習筆記（七）–Input輸入裝置

Windows.Device.Input介面提供了識別可用的輸入裝置並獲得這些裝置的資訊

KeyboardCapabilities

用於判斷當前是否串連了鍵盤裝置

其屬性KeyboardPresent進行判斷，當為0時表示未串連，不為0時表示已串連

Windows.Devices.Input.KeyboardCapabilities KeyboardCapabilities = new Windows.Devices.Input.KeyboardCapabilities();string status = string.Format("There is {0} keyboard present\n", KeyboardCapabilities.KeyboardPresent != 0 ? "a" : "no");

MouseCapabilities

用於判斷當前是否串連了滑鼠裝置

其屬性比KeyboardCapabilities多了些，如下：

HorizontalWheelPresent 該值表明是否有帶水平滾輪的滑鼠串連

MousePresent 表明是否有滑鼠串連

NumberOfButtons 該值表明當前串連的滑鼠中按鈕的數量，若有多個滑鼠串連，則返回滑鼠按鍵個數最多的數量

SwapButtons 該值表明當前串連的滑鼠裝置中是否具有左右交換按鈕的

VerticalWheelPresent 該值表明當前串連的滑鼠裝置中是否有垂直的滾輪

Windows.Devices.Input.MouseCapabilities MouseCapabilities = new Windows.Devices.Input.MouseCapabilities(); String info = string.Format("There is {0} mouse present\n", MouseCapabilities.MousePresent != 0 ? "a" : "no"); info += string.Format("There is {0} vertical mouse wheel present\n", MouseCapabilities.VerticalWheelPresent != 0 ? "a" : "no"); info += string.Format("There is {0} horizontal mouse wheel present\n", MouseCapabilities.HorizontalWheelPresent != 0 ? "a" : "no"); info += string.Format("The user has {0}opted to swap the mouse buttons\n", MouseCapabilities.SwapButtons != 0 ? "" : "not "); info += string.Format("The mouse has {0} button(s)\n", MouseCapabilities.NumberOfButtons);

TouchCapabilities

獲得串連的觸摸數字化儀的功能

Contats 表明支援所有數字化儀的最小連絡人數量

TouchPresent 表明當前終端是否有資料化儀

Windows.Devices.Input.TouchCapabilities TouchCapabilities = new Windows.Devices.Input.TouchCapabilities(); String info = string.Format("There is {0} digitizer present\n", TouchCapabilities.TouchPresent != 0 ? "a" : "no");info += string.Format("The digitizer supports {0} contacts\n", TouchCapabilities.Contacts);

PointerDevice

識別串連的指標裝置及它們的功能

var PointerDeviceList = Windows.Devices.Input.PointerDevice.GetPointerDevices();            string device="";            foreach (Windows.Devices.Input.PointerDevice PointerDevice in PointerDeviceList)            {                 if (PointerDevice.PointerDeviceType == Windows.Devices.Input.PointerDeviceType.Mouse)                {                    device ="mouse";                }                else if (PointerDevice.PointerDeviceType == Windows.Devices.Input.PointerDeviceType.Pen)                {                    device= "pen";                }                else                {                    device= "touch";                }             }

 今天就看了一點輸入裝置的功能用法,研究SMS收發資訊的功能時,卻被剛開始的SmsDevice.GetDefaultAsync()擷取資訊裝置給絆住了,報的錯誤是”服務尚未啟動。 (異常來自 HRESULT:0x80070426) ”,不知道是不是要先開啟什麼,望知者還能提醒一番^_^
