MFC程序记录下用户所做的操作和修改，写入数据库里怎么做

[Clampard]

新手，吧里大神可以说说思路吗，

例如qq上的个人资料框，有昵称、个性签名、电话、邮箱、地址 一个用户改了昵称和个性签名， 数据库把这个操作记录下来，例如数据库记录了：把昵称XXX改为XXX, 把个性签名XXX改为XXX。 这样要怎么实现呢？

数据库可以简单的就是记录每次用户最新的信息，然后你需要知道这个变化分析就再对数据库同一个用户进行记录分析等。

我在数据库有一个操作日志表用来记录用户操作，而且程序里可以查询得到，如果可以实现以上功能，这样用户都可以看到别人干了什么，自己干了什么，看上去直接了当，目前就是比较难下手，。

先实现数据库增、删、改、查的函数，然后直接调用就行了。

如果一个对话框上的编辑框太多了，怎么找出改变过的编辑框

试试 CBTProc The CBTProc hook procedure is an application-defined or library-defined callback function used with the SetWindowsHookEx function. The system calls this function before activating, creating, destroying, minimizing, maximizing, moving, or sizing a window; before completing a system command; before removing a mouse or keyboard event from the system message queue; before setting the keyboard focus; or before synchronizing with the system message queue. A computer-based training (CBT) application uses this hook procedure to receive useful notifications from the system. The HOOKPROC type defines a pointer to this callback function. CBTProc is a placeholder for the application-defined or library-defined function name. LRESULT CALLBACK CBTProc( int nCode, // hook code WPARAM wParam, // depends on hook code LPARAM lParam // depends on hook code ); Parameters nCode Specifies a code that the hook procedure uses to determine how to process the message. This parameter can be one of the following values: Value Meaning HCBT_ACTIVATE The system is about to activate a window. HCBT_CLICKSKIPPED The system has removed a mouse message from the system message queue. Upon receiving this hook code, a CBT application must install a WH_JOURNALPLAYBACK hook procedure in response to the mouse message. HCBT_CREATEWND A window is about to be created. The system calls the hook procedure before sending theWM_CREATE orWM_NCCREATE message to the window. If the hook procedure returns a nonzero value, the system destroys the window; theCreateWindow function returns NULL, but theWM_DESTROY message is not sent to the window. If the hook procedure returns zero, the window is created normally. At the time of the HCBT_CREATEWND notification, the window has been created, but its final size and position may not have been determined and its parent window may not have been established. It is possible to send messages to the newly created window, although it has not yet received WM_NCCREATE or WM_CREATE messages. It is also possible to change the position in the Z order of the newly created window by modifying the hwndInsertAfter member of the CBT_CREATEWND structure. HCBT_DESTROYWND A window is about to be destroyed. HCBT_KEYSKIPPED The system has removed a keyboard message from the system message queue. Upon receiving this hook code, a CBT application must install a WH_JOURNALPLAYBACK_hook hook procedure in response to the keyboard message. HCBT_MINMAX A window is about to be minimized or maximized. HCBT_MOVESIZE A window is about to be moved or sized. HCBT_QS The system has retrieved a WM_QUEUESYNC message from the system message queue. HCBT_SETFOCUS A window is about to receive the keyboard focus. HCBT_SYSCOMMAND A system command is about to be carried out. This allows a CBT application to prevent task switching by means of hot keys. If nCode is less than zero, the hook procedure must pass the message to the CallNextHookEx function without further processing and should return the value returned by CallNextHookEx. wParam Depends on the nCode parameter. For details, see the following Remarks section. lParam Depends on the nCode parameter. For details, see the following Remarks section. Return Values The value returned by the hook procedure determines whether the system allows or prevents one of these operations. For operations corresponding to the following CBT hook codes, the return value must be 0 to allow the operation, or 1 to prevent it: HCBT_ACTIVATE HCBT_CREATEWND HCBT_DESTROYWND HCBT_MINMAX HCBT_MOVESIZE HCBT_SETFOCUS HCBT_SYSCOMMAND For operations corresponding to the following CBT hook codes, the return value is ignored: HCBT_CLICKSKIPPED HCBT_KEYSKIPPED HCBT_QS Remarks The hook procedure should not install a WH_JOURNALPLAYBACK_hook hook procedure except in the situations described in the preceding list of hook codes. This hook procedure must be in a dynamic-link library (DLL). An application installs the hook procedure by specifying the WH_CBT hook type and the address of the hook procedure in a call to the SetWindowsHookEx function.
