我嘗試註冊我的指針輸入C#WPF窗口,讓所有的觸摸輸入被重定向到它,但RegisterPointerInputTarget正在恢復對正在傳遞的目標窗口句柄假。 我的代碼如下RegisterPointerInputTarget()函數提供虛假
//declarations
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
IntPtr hWnd;
int abc;
public MainWindow()
{
InitializeComponent();
System.Windows.Interop.WindowInteropHelper windowHwnd = new System.Windows.Interop.WindowInteropHelper(this);
hWnd = windowHwnd.EnsureHandle();
hWnd = windowHwnd.Handle;
Minimize.Enable(this);
this.abc = IWrapper.Rpit(hWnd);
}
internal class IWrapper
{
const string SHADOW_DLL_NAME = "RPIT_TEST.dll";
[DllImport(SHADOW_DLL_NAME)]
public static extern int Rpit(IntPtr hwnd);
}
}
}
而且RegisterPointerInputTarget功能在RPIT_TEST.dll定義(作爲一個C++函數)如下:
extern "C" int __declspec (dllexport) __stdcall Rpit(HWND hwnd)
{
typedef enum tagPOINTER_INPUT_TYPE {
PT_POINTER = 0x00000001,
PT_TOUCH = 0x00000002,
PT_PEN = 0x00000003,
PT_MOUSE = 0x00000004
} POINTER_INPUT_TYPE;
return RegisterPointerInputTarget(hwnd,PT_POINTER);
}
我尋覓了很多可能存在的錯誤 任何幫助將不勝感激
我試圖調試我的uiAccess的項目設置爲true,我得到類似這樣的錯誤, http://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/7a42efab-5ce8-456f- 8a58-dfedbc2cefcb/debugging-with-uiaccesstrue 你知道如何克服這個問題嗎? –
更新:我跟着步驟從這裏, http://stackoverflow.com/questions/12192504/debugging-with-visual-studio-2012-windows-8-and-user-account-control ,似乎執行,但函數仍然返回false:/ –
