SetWindowsHookExA的问题，求大佬

若梦随遇而安

#WH_CALLWNDPROC 请问能不能获取到#WM_SETTEXT的消息跟消息内容呢

南风知意

CallWndProc
The CallWndProc hook procedure is an application-defined or library-defined callback function used with the SetWindowsHookEx function. The system calls this function whenever theSendMessage function is called. Before passing the message to the destination window procedure, the system passes the message to the hook procedure. The hook procedure can examine the message; it cannot modify it.

The HOOKPROC type defines a pointer to this callback function. CallWndProc is a placeholder for the application-defined or library-defined function name.

LRESULT CALLBACK CallWndProc(
  int nCode,      // hook code
  WPARAM wParam,  // current-process flag
  LPARAM lParam   // address of structure with message data
);

Parameters
nCode
Specifies whether the hook procedure must process the message. If nCode is HC_ACTION, the hook procedure must process the message. If nCode is less than zero, the hook procedure must pass the message to the CallNextHookEx function without further processing and must return the value returned by CallNextHookEx.
wParam
Specifies whether the message was sent by the current thread. If the message was sent by the current thread, it is nonzero; otherwise, it is zero.
lParam
Pointer to a CWPSTRUCT structure that contains details about the message.

typedef struct tagCWPSTRUCT { // cwps
    LPARAM  lParam;
    WPARAM  wParam;
    UINT    message;
    HWND    hwnd;
} CWPSTRUCT;

msdn中都有详细的定义,lParam在易语言中设置为CWPSTRUCT类型即可 ,会自动传入一个指针读取到结构,判断message是否为WM_SETTEXT类型即可

可以啊。WH_CALLWNDPROCRET 这个也可以

大佬，你好，请问一下。那么如何取到消息值呢。我百度了很多资料，基本都是LPARAM 然后直接转一下就可以了。E中如何取到这个消息值呢

我有尝试过用RtlMoveMemory将结构体复制出来，但其中的message好像并不正确
