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：

        }
        //析构函数中卸载钩子
        ~KeyboardHook()
        {
            Stop();
        }
    }
}
 

创建全局Hook：

view plaincopy to clipboardprint?
        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());  
} 
        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：

view plaincopy to clipboardprint?
        [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");  
        }  
    }  
} 
        [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：

view plaincopy to clipboardprint?
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);  
    }  
} 
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

view plaincopy to clipboardprint?
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  
    }  
} 
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，

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());  
} 
        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：

view plaincopy to clipboardprint?
        [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");  
        }  
    }  
} 
        [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：

view plaincopy to clipboardprint?
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);  
    }  
} 
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

view plaincopy to clipboardprint?
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  
    }  
} 
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，

界面如下：

 

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：

        }

        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());
}
