我剛剛開始使用InjectTouchInput for Windows 8 Consumer Preview。我一直在繞圈轉圈試圖讓這件事情起作用,但似乎無法讓它實際上互動。我正在使用C#,目前我只是在兩個文本框和按鈕中創建一個帶有x和y座標的地鐵界面,它們調用下面的函數在這些座標處觸摸屏幕。這是做這件事的正確方法嗎?InjectTouchInput Windows 8 C#不工作(返回false)

protected unsafe class TouchDriver 
    { 


     public struct POINTER_TOUCH_INFO { 
      public POINTER_INFO pointerInfo; // An embedded POINTER_INFO header structure. 

      public TOUCH_FLAGS touchFlags;   // Currently none. 

      public Rect rcContact;    // Pointer contact area in pixel screen coordinates. By default, if the device does not report a contact area, this field defaults to a 0-by-0 rectangle centered around the pointer location. 

      public UInt32 orientation;   // A pointer orientation, with a value between 0 and 359, where 0 indicates a touch pointer aligned with the x-axis and pointing from left to right; increasing values indicate degrees of rotation in the clockwise direction. 
             // This field defaults to 0 if the device does not report orientation. 

      public UInt32 pressure;   // Pointer pressure normalized in a range of 0 to 256. 
             // This field defaults to 128 if the device does not report pressure. 
             // Question: Can this go from 0 to 1024 to match pen pressure?

幾乎所有我試圖從我在網上找到的InjectTouchInput API中解除。我可以InitializeTouchInject罰款,其注入位返回false,我不知道爲什麼。

調用InjectTouchInput後GetLastError返回什麼? InjectTouchInput對於它的輸入參數很挑剔,可能有些東西並不完美。 – 2012-04-14 22:26:59

我繼續在C++中基於Microsoft提供的示例創建一些自定義函數,然後使用與之前相同的定義將其導入到C#中,但沒有與所有類型檢查,指針和參數放在一起之前引起頭痛。

,我已經使用的DLL文件是TouchInjectionDriver.dll並且可以在這裏找到:

下面是我用來實現它的C#代碼。

太棒了!你是如何將TouchInjectionDriver.dll引用到你的C#項目中的?對於我來說,當我嘗試在Visual Studio中添加引用時,我得到「無法添加引用...請確保該文件是可訪問的,並且它是有效的程序集或COM組件」。任何想法? 我也在命令提示符下嘗試過「regsvr32 TouchInjectionDriver.dll」,但得到了類似的錯誤! 謝謝! – ala 2012-04-16 12:10:15

您不需要在項目中包含.dll作爲參考。 (事實上,除非你正在構建一個C++項目,否則你不能) 儘管如此,你可以將它包含在資源中,所以你知道它將與你的信息一起打包和部署。 只要你的可執行文件可以找到dll,包裝代碼應該可以運行 – 2013-04-11 21:48:44

我得到了這個運行,但是託管的InjectTouch也爲我返回false,兩者都連接了真實的觸摸屏。 – 2013-12-21 00:14:26
