C#钩子设置不成功的问题
我的应用程序的主窗体中包含了一个自定义控件，自定义控件相当于一个窗体容器，现在，我将windowWord窗体嵌套在这个自定义控件中，我想给windowWord窗体设置一个钩子用于获取这个窗体的鼠标键盘消息！注意，windowWord就是独立的一个MircsoftWord窗体，激活此窗体后，该窗体的进程ID与进程句柄应该都已经获取正确！
下面是我设置钩子的代码：
public void HookStart() { int wordCalcID = 0; int wordCalcProcess = 0; const int PROCESS_ALL_ACCESS = 0x1F0FFF; const int PROCESS_VM_READ = 0x0010; const int PROCESS_VM_WRITE = 0x0020; if(wordWnd!= null) { GetWindowThreadProcessId((System.IntPtr)wordWnd, out wordCalcID); wordCalcProcess = OpenProcess(PROCESS_ALL_ACCESS, false, wordCalcID); } else { MessageBox.Show("Not Found WordWindow"); } if (hKeyboardHook == 0) { // 创建HookProc实例 KeyboardHookProcedure = new HookProc(KeyAndMouseHookProc); // 设置线程钩子 if (wordCalcProcess !=0) { hKeyboardHook = SetWindowsHookEx(7, KeyboardHookProcedure,(System.IntPtr)wordCalcProcess, 0); // 如果设置钩子失败 if (hKeyboardHook == 0) { HookStop(); throw new Exception("SetWindowsHookEx failed."); } } else if (wordCalcProcess==0) { MessageBox.Show("ThreadId found error"); } } }
