c#实现魔兽(warIII)中显血和改键功能 (附源码)(不影响聊天打字)

在论坛中看到有人提到 这个功能，感觉应该能实现，周末就抽时间写出来了，在这里分享下：

思路：Hook+SendMessage，

首先，因为我们要改的键war3不是自己写的程序，所以只能用Hook来监控键盘的按键：

键盘Hook：

using System;

using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace quickey
{
    public class KeyboardHook
    {
        private const int WM_KEYDOWN = 0x100;//按下消息
        private const int WM_KEYUP = 0x101;//松开消息
        private const int WM_SYSKEYDOWN = 0x104;
        private const int WM_SYSKEYUP = 0x105;

        //全局事件
        public event KeyEventHandler OnKeyDownEvent;
        public event KeyEventHandler OnKeyUpEvent;
        public event KeyPressEventHandler OnKeyPressEvent;

        static int hKeyboardHook = 0;

        //鼠标常量
        public const int WH_KEYBOARD_LL = 13;

        public delegate int HookProc(int nCode, Int32 wParam, IntPtr lParam);

        //声明键盘钩子事件类型
        HookProc KeyboardHookProcedure;

        /// <summary>
        /// 声明键盘钩子的封送结构类型
        /// </summary>
        [StructLayout(LayoutKind.Sequential)]
        public class KeyboardHookStruct
        {
            public int vkCode;//表示一个1到254间的虚拟键盘码
            public int scanCode;//表示硬件扫描码
            public int flags;
            public int time;
            public int dwExtraInfo;
        }

        //安装钩子
        [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
        public static extern int SetWindowsHookEx(int idHook, HookProc lpfn, IntPtr hInstance, int threadId);
        //下一个钩子
        [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
        public static extern int CallNextHookEx(int idHook, int nCode, Int32 wParam, IntPtr lParam);
        //卸载钩子
        [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
        public static extern bool UnhookWindowsHookEx(int idHook);

        private int KeyboardHookProc(int nCode, Int32 wParam, IntPtr lParam)
        {
            if ((nCode >= 0) && (OnKeyDownEvent != null || OnKeyUpEvent != null || OnKeyPressEvent != null))
            {
                KeyboardHookStruct MyKBHookStruct = (KeyboardHookStruct)Marshal.PtrToStructure(lParam, typeof(KeyboardHookStruct));

                //引发OnKeyDownEvent
                if (OnKeyDownEvent != null && (wParam == WM_KEYDOWN || wParam == WM_SYSKEYDOWN))
                {
                    Keys keyData = (Keys)MyKBHookStruct.vkCode;
                    KeyEventArgs e = new KeyEventArgs(keyData);
                    OnKeyDownEvent(this, e);
                }
            }
            return CallNextHookEx(hKeyboardHook, nCode, wParam, lParam);
        }

         public void Start()
        {
            if (hKeyboardHook == 0)
            {
                KeyboardHookProcedure = new HookProc(KeyboardHookProc);
                //hKeyboardHook = SetWindowsHookEx(WH_KEYBOARD_LL, KeyboardHookProcedure, Marshal.GetHINSTANCE(System.Reflection.Assembly.GetExecutingAssembly().GetModules()[0]), 0);
                using (System.Diagnostics.Process curProcess = System.Diagnostics.Process.GetCurrentProcess())
                using (System.Diagnostics.ProcessModule curModule = curProcess.MainModule)
                hKeyboardHook = SetWindowsHookEx(WH_KEYBOARD_LL, KeyboardHookProcedure,GetModuleHandle(curModule.ModuleName), 0);

                if (hKeyboardHook == 0)
                {
                    Stop();
                    throw new Exception("Set GlobalKeyboardHook failed!");
                }
            }
        }
        public void Stop()
        {
            bool retKeyboard = true;
            if (hKeyboardHook != 0)
            {
                retKeyboard = UnhookWindowsHookEx(hKeyboardHook);
                hKeyboardHook = 0;
            }
            if (!retKeyboard)
                throw new Exception("Unload GlobalKeyboardHook failed!");
        }

        //构造函数中安装钩子
        public KeyboardHook()
        {
            Start();
        }
        //析构函数中卸载钩子
        ~KeyboardHook()
        {
            Stop();
        }
    }
}

创建全局Hook：

        KeyboardHook hook = new KeyboardHook();
private void Form1_Load(object sender, EventArgs e)
        {
            hook.OnKeyDownEvent += new KeyEventHandler(hook_OnKeyDownEvent);

        }

        void hook_OnKeyDownEvent(object sender, KeyEventArgs e){
//在这里就可以截获到所有的键盘按键了
MessageBox.show(e.keyValue.toString());
}

打开war3，在里面按了几下键盘，弹出了看，有好几个对话框，说明可以监测到war3里面的按键，

我的思路是向窗口发送消息，必须找到获取窗口的句柄才行：

        [DllImport("USER32.DLL")]
        public static extern IntPtr FindWindow(string lpClassName,string lpWindowName);

bool isHookEnable = true;//全局变量，指示Hook是否作用
private const int WM_KEYDOWN = 0x100;
private const int WM_KEYUP = 0x101;
void hook_OnKeyDownEvent(object sender, KeyEventArgs e)
{
	if (e.KeyCode == Keys.Scroll)
	{
		isHookEnable = !isHookEnable;
		this.Text = isHookEnable ? "quickey-开启":"quickey-停用";
		notifyIcon1.Text = this.Text;
	}
	if (isHookEnable)
	{
		IntPtr war3 = FindWindow(null, "Warcraft III");
		if (war3 != IntPtr.Zero)
		{
			MessageBox.show("找到war3了");
		}
	}
}

运行，按了下弹出“找到war3了”这样就获得了war3窗口的句柄了

，剩下就是向窗口发送按键的消息了：

先声明：
[DllImport("User32.DLL")]
public static extern int SendMessage(IntPtr hWnd,uint Msg, int wParam, int lParam);

if (isHookEnable)
{
	IntPtr war3 = FindWindow(null, "Warcraft III");
	if (war3 != IntPtr.Zero)
	{
		if (e.KeyCode == Keys.D)
                        SendMessage(war3, WM_KEYDOWN, (int)Keys.C, 0);
	}
}

打开war3到创建游戏界面，按了下D，嗯？创建游戏了，说明消息发送成功

这样就可以将截获的按键来发送指定消息来“更改”按键了

private const int KEY_QUOTLEFT = 219;//键盘上 [ 键的代码
private const int KEY_QUOTRIGHT = 221;//键盘上 ] 键的代码
if (isHookEnable)
{
	IntPtr war3 = FindWindow(null, "Warcraft III");
	if (war3 != IntPtr.Zero)
	{
		SetForegroundWindow(war3);//将war3窗口置前，这一句我自己测试时可以不用，但去掉这一句后朋友那里说不行
         SendMessage(war3, WM_KEYDOWN, KEY_QUOTLEFT,0);//按下[键就可以显示友军的血了
         SendMessage(war3, WM_KEYDOWN, KEY_QUOTRIGHT, 0);
         
		SendMessage(war3, WM_KEYDOWN, int.Parse(hash[e.KeyValue.ToString()].ToString()), 0);//按下
		SendMessage(war3, WM_KEYUP, int.Parse(hash[e.KeyValue.ToString()].ToString()), 0);//松开
	}
}

ok,大体 就是这个思路，具体的代码可以到下面下载，

jardyson 写道

LZ标题是显血，怎么内容就成SENDMESSAGE了呢，这两者完成搭不着边，显血是要找WAR的人物血条基址，跟发送窗口信息没关系。

不玩魔兽的吧你
里面有快捷键的
