如何禁用Wpf中的acrobat reader contextmenu？

Question

我在使用Acrobat ActiveX的應用程序中顯示PDF文檔。 我想知道是否可以禁用右鍵單擊PDF文檔？

我以前的解決方案沒有工作，所以還有一個解決方案。您只需在接收鼠標通知的子窗口上設置鼠標鉤子。

public class AcrobatReader : AxAcroPDF 
{ 
    private const int WH_MOUSE_LL = 14; 
    private const int WM_RBUTTONDOWN = 0x0204; 

    private static LowLevelMouseProc _proc = HookCallback; 
    private static IntPtr _hookID = IntPtr.Zero; 

    public AcrobatReader() 
    { 
     _hookID = SetWindowsHookEx(WH_MOUSE_LL, _proc, FindWindow(null, "avpageview"), 0); 
    } 

    ~AcrobatReader() 
    { 
     if (_hookID != IntPtr.Zero) 
     { 
      UnhookWindowsHookEx(_hookID); 
      _hookID = IntPtr.Zero; 
     } 
    } 

    private static IntPtr HookCallback(int nCode, IntPtr wParam, IntPtr lParam) 
    { 
     if (nCode >= 0 && (IntPtr)WM_RBUTTONDOWN == wParam) 
     { 
      return new IntPtr(1); 
     } 
     return CallNextHookEx(_hookID, nCode, wParam, lParam); 
    } 

    private delegate IntPtr LowLevelMouseProc(int nCode, IntPtr wParam, IntPtr lParam); 

    [DllImport("user32.dll", SetLastError = true)] 
    private static extern IntPtr SetWindowsHookEx(int idHook, LowLevelMouseProc lpfn, IntPtr hMod, uint dwThreadId); 

    [DllImport("user32.dll", SetLastError = true)] 
    [return: MarshalAs(UnmanagedType.Bool)] 
    private static extern bool UnhookWindowsHookEx(IntPtr hhk); 

    [DllImport("user32.dll", SetLastError = true)] 
    private static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode, IntPtr wParam, IntPtr lParam); 

    [DllImport("user32.dll", SetLastError = true)] 
    private static extern IntPtr FindWindow(string lpClassName, string lpWindowName); 
}
