g_hWnd=m_hWnd 是什么意思？区别呢？g_hInst和g_hWnd;区别呢，这些变量时系统的还是可以人为定义

wykqhyjs 2010-07-23 02:34:55

下面代码中的g_hWnd=m_hWnd 是什么意思，另外HINSTANCE 和HWND 有什么区别
2.示例程序：
1.新建一基于对话框工程，InnerHook,此过程的钩子是只拦截本进程的。
2.在OnInitDialog()中添加代码：
g_hWnd=m_hWnd;
g_hMouse=SetWindowsHookEx(WH_MOUSE,MouseProc,NULL,GetCurrentThreadId());设置了鼠标钩子
g_hKeyboard=SetWindowsHookEx(WH_KEYBOARD,KeyboardProc,NULL,GetCurrentThreadId());设置了键盘钩子
3.完成钩子函数的编写：
HHOOK g_hKeyboard=NULL;
HHOOK g_hMouse;
HWND g_hWnd=NULL;

LRESULT CALLBACK MouseProc(
int nCode, // hook code
WPARAM wParam, // message identifier
LPARAM lParam // mouse coordinates
)
{
return 1;
}
下面代码中的g_hWnd=m_hWnd 是什么意思？什么用处

随便问下
HINSTANCE g_hInst;
HWND g_hWnd;
是经常看见的2个东东，他们分别是什么意思？区别呢？为什么他们的类型不同？一个是HINSTANCE 一个是HWND
另外HINSTANCE 和HWND 有什么区别
好几个问题谢谢

g_hWnd, g_hMouse,g_hKeyboard这三个变量应该是在类外部声明的全局变量，且在OnInitDialog()函数之前初始化为NULL；OnInitDialog()函数对其初始化赋值，并安装钩子，而后钩子响应函数开始运行。
HINSTANCE 是应用程序实例句柄，HWND 是窗口句柄

MSDN里面已经讲得很清楚了

代码中g_hWnd的定义是这样的：HWND g_hWnd=NULL;
m_hWnd是默认的窗口句柄只要在CWnd类继承的类都有
g_hWnd=m_hWnd就是窗口句柄的赋值

HINSTANCE g_hInst;不清楚

那赋值在逻辑上干嘛用啊

m_hWnd是CWnd类的成员变量，是CWnd对象相关联的窗口的句柄，你上面的代码应该是一个钩子代码，估计钩子程序在后面要用到这个下钩子的窗口的句柄，所以定义了一个全局变量g_hWnd用来保存这个句柄。
你所说的有什么用，从你的代码上看，g_hWnd应该是一个共享的变量，如果是全局钩子中要向下钩子的窗口发消息的话，一般就用到这个了。不过，这个用处只是我猜想的，总之，g_hWnd=m_hWnd就是将主对话框的窗口句柄保存下来，方便在别的地方用。

Question: HINSTANCE 和HWND 有什么区别

Answer: HINSTANCE 和 HWND都是句柄，但又有不同，

        HINSTANCE 是应用程序实例句柄， HWND 是窗口句柄

查了MSDN
An HINSTANCE to the current instance of the application. If called from within a DLL linked with the USRDLL version of MFC, an HINSTANCE to the DLL is returned.

大概意思就是Dll所返回的句柄
