使鼠标单击左键的VB命令是什么？

Question

我说的不是触发控件的click事件后执行指定命令，而是触发了某一事件后使鼠标在指定坐标单击左键。

麻烦再说一下使单击右键，双击左键和滑动滚轮的命令

　1、首先我们要用FindWindow,知道游戏窗口的句柄，因为我们要通过它来得知游戏的运行后所在进程的ID，下面就是FindWindow的用法：

HWND FindWindow(

LPCTSTR lpClassName, // pointer to class name
LPCTSTR lpWindowName // pointer to window name
);

　　2、我们GetWindowThreadProcessId来得到游戏窗口相对应进程的进程ID，函数用法如下：

DWORD GetWindowThreadProcessId(

HWND hWnd, // handle of window
LPDWORD lpdwProcessId // address of variable for process identifier
);

　　3、得到游戏进程ID后，接下来的事是要以最高权限打开进程，所用到的函数OpenProcess的具体使用方法如下：

HANDLE OpenProcess(

DWORD dwDesiredAccess, // access flag
BOOL bInheritHandle, // handle inheritance flag
DWORD dwProcessId // process identifier
);

　　在dwDesiredAccess之处就是设存取方式的地方，它可设的权限很多，我们在这里使用只要使用PROCESS_ALL_ACCESS 来打开进程就可以，其他的方式我们可以查一下MSDN。

　　4、打开进程后，我们就可以用函数对存内进行操作，在这里我们只要用到WriteProcessMemory来对内存地址写入数据即可（其他的操作方式比如说：ReadProcessMemory等，我在这里就不一一介绍了），我们看一下WriteProcessMemory的用法：

BOOL WriteProcessMemory(

HANDLE hProcess, // handle to process whose memory is written to
LPVOID lpBaseAddress, // address to start writing to
LPVOID lpBuffer, // pointer to buffer to write data to
DWORD nSize, // number of bytes to write
LPDWORD lpNumberOfBytesWritten // actual number of bytes written
);

　　5、下面用CloseHandle关闭进程句柄就完成了。

　　这就是这类游戏外挂的程序实现部份的方法，好了，有了此方法，我们就有了理性的认识，我们看看实际例子，提升一下我们的感性认识吧，下面就是XX游戏的外挂代码，我们照上面的方法对应去研究一下吧：

const
ResourceOffset: dword = $004219F4;
resource: dword = 3113226621;
ResourceOffset1: dword = $004219F8;
resource1: dword = 1940000000;
ResourceOffset2: dword = $0043FA50;
resource2: dword = 1280185;
ResourceOffset3: dword = $0043FA54;
resource3: dword = 3163064576;
ResourceOffset4: dword = $0043FA58;
resource4: dword = 2298478592;
var
hw: HWND;
pid: dword;
h: THandle;
tt: Cardinal;
begin
hw := FindWindow('XX', nil);
if hw = 0 then
Exit;
GetWindowThreadProcessId(hw, @pid);
h := OpenProcess(PROCESS_ALL_ACCESS, false, pid);
if h = 0 then
Exit;
if flatcheckbox1.Checked=true then
begin
WriteProcessMemory(h, Pointer(ResourceOffset), @Resource, sizeof(Resource), tt);
WriteProcessMemory(h, Pointer(ResourceOffset1), @Resource1, sizeof(Resource1), tt);
end;
if flatcheckbox2.Checked=true then
begin
WriteProcessMemory(h, Pointer(ResourceOffset2), @Resource2, sizeof(Resource2), tt);
WriteProcessMemory(h, Pointer(ResourceOffset3), @Resource3, sizeof(Resource3), tt);
WriteProcessMemory(h, Pointer(ResourceOffset4), @Resource4, sizeof(Resource4), tt);
end;
MessageBeep(0);
CloseHandle(h);
close;

这么复杂？
没有一个简单的单词或词组加坐标的方法么？

追答

前面带private的都是定义，看起来复杂，其实后面加注释的才是真正有用的方法。
