C#实现驱动级模拟按键

Home / Article MrLee 2016-8-31 4200

原来看过winio.dll，但是好多人说没用。后来也没有再研究。这里发篇文章，博主说已经成功。既然如此，收藏吧！
昨天没事又玩了下仙剑4(俺是仙剑迷

), 由于仙4已经玩了好几次,于是准备写个VBS脚本来实现一些自动打怪和自动行走功能,结果发现除了发送F1到F12有效外,其他按键对游戏完全没有效果。(在打怪界面使用keybd_event还有点效果) 经过了解和查看了仙4的安装要求,确定应是DirectX的原因,(仙4要求DirectX9.0以上) DirectX为了提高游戏的响应速度直接是读端口的输入,也难怪对我的模拟按键不理睬。由于网上已经有使用Winio.dll实现驱动级按键,我这就直接拿来.全部代码如下:

            btScancode = MapVirtualKey((byte)vKeyCoad, 0);
            KBCWait4IBE(); // 'wait for buffer gets empty
            SetPortVal(KBC_KEY_CMD, (IntPtr)0xD3, 1);// 'send write command
            KBCWait4IBE();
            SetPortVal(KBC_KEY_DATA, (IntPtr)(btScancode | 0x80), 1);// 'write in io
        }
        /// Simulate mouse up
        public static void MyMouseUp(int vKeyCoad)
        {
            int btScancode = 0;
            btScancode = MapVirtualKey((byte)vKeyCoad, 0);
            KBCWait4IBE(); // 'wait for buffer gets empty
            SetPortVal(KBC_KEY_CMD, (IntPtr)0xD3, 1); //'send write command
            KBCWait4IBE();
            SetPortVal(KBC_KEY_DATA, (IntPtr)(btScancode | 0x80), 1);// 'write in io
        }
    }
}

然后新建一个窗体应用,在Form1_Load事件中添加WinIo.Initialize();来初始化驱动,在Form1_FormClosed事件中使用WinIo.Shutdown();卸载驱动。
在button事件中实现模拟按键如下:

     private void button1_Click(object sender, EventArgs e)
        {
            int hwnd = FindWindow(null, "PAL4-Application");
            IntPtr p = new IntPtr(hwnd);
            if (p == IntPtr.Zero)
                return;
            SetActiveWindow(p);
            //设置为活动窗体，防止被其他窗口挡住
            SetForegroundWindow(p);
            Thread.Sleep(1000);
            int i = 0;
            while (i < 5)
            {
                WinIo.MykeyDown(VKKey.VK_SPACE);
                Thread.Sleep(100);
                WinIo.MykeyUp(VKKey.VK_SPACE);
                Thread.Sleep(100);
                WinIo.MykeyDown(VKKey.VK_S);
                Thread.Sleep(100);
                WinIo.MykeyUp(VKKey.VK_S);
                Thread.Sleep(500);
                WinIo.MykeyDown(VKKey.VK_D);
                Thread.Sleep(100);
                WinIo.MykeyUp(VKKey.VK_D);
                Thread.Sleep(500);
                WinIo.MykeyDown(VKKey.VK_A);
                Thread.Sleep(100);
                WinIo.MykeyUp(VKKey.VK_A);
                i++;
            }
        }

注意上面的代码是运行在unsafe模式下的,其中FindWindow、SetForegroundWindow、 SetActiveWindow导入如下:
[DllImport("user32.dll", EntryPoint = "FindWindow")] public static extern int FindWindow(string lpClassName, string lpWindowName);
[DllImport("user32.dll", EntryPoint = "SetForegroundWindow")] public static extern bool SetForegroundWindow(IntPtr hWnd); [DllImport("user32.dll")] static extern IntPtr SetActiveWindow(IntPtr hWnd); 64位的WinIo包括源码下载地址: http://www.internals.com/
如果出现WinIo.Initialize()初始化驱动失败的情况,有几点就要注意:
1.确保你当前用户的权限为管理员权限;
2.使用命令“bcdedit /set testsigning on”进入WIN7测试模式,然后重启电脑后再运行上面的代码。
3.64位系统应加载WinIo64.dll,32位系统加载WinIo32.dll.(我的环境是WIN7 64位),PS:不需要引用dll的,PInvoke模式是使用DllImport特性或LoadLibrary来加载非托管代码的,所以无论你怎么引用都会报"未能加载***.dll"的错误的。
接下来就自己写自动行走和打怪的WG吧。(注意:很多网游保护都会检测这种驱动级按键,自己小心被封号吧)
