众所周知：WIN32子动态库user32.dll 封装了系统定义的全局标准控件类和WNDPROCESS,然后共享给各个Application,系统启动会加载入user32，然后注册它们的.仅仅是感兴趣没有其他目的
俺是一个小菜鸟,结合2k代码只分析应用层。 机器环境双核 xp sp2。
user32.dll中的函数命名一般有统一性,很有意思.呵呵.算是它的native风格定义吧。它们会进一步校验上层传的参数,并且适当设置GetLastError等细节,然后继续分发到ntdll Native层,或经过系统中断服务层进入win32.sys驱动层完成调用等.
比如:DispatchMessageA 调用DispatchMessageWorker，又而会调用 UserCallWinProcCheckWow,然后最终调用到InternalCallWinProc,把消息分发到我们的窗口的WinProc过程. 这个过程完全是在应用层进行的。
再如:SendMessageA -->SendMessageWorker---> UserCallWinProcCheckWow---> InternalCallWinProc-->MyDiyWinProc。也是在应用层。
这个:DefWindowProc-->DefWindowProcWorker--->InternalCallWinProc--->RealDefWindowProcWorker-->消息表---事件表调度>NtUserMessageCall--->进入内核和win32.sys-->处理完毕，返回应用层。有内核辅助处理。
先看看user32注册控件类的地方:

Win2k头文件 user.h中找了fnid的说明,fnid更类似(窗口类的)索引,有起始范围。有兴趣的可以看看.
/*
* Server side address constants. When we want to call a server side proc,
* we pass an index indentifying the function, rather than the server side
* address itself. More robust. The functions between WNDPROCSTART/END
* have client side sutbs which map to this routines.
*
* Adding a new FNID (This is just what I figured out...so fix it if wrong or incomplete)
* -Decide what range it should be in:
* FNID_WNDPROCSTART to FNID_WNDPROCEND: Server side proc with client
* stub
* FIND_CONTROLSTART to FNID_CONTROLEND: Client side controls with no
* server side proc
* After FNID_CONTROLEND: other, like server side only procs or client
* side only....
* -Make sure to adjust FNID_*START and FNID_*END appropriately.
* -If the ID is to be associated with a window class, and it is for all
* windows of the class, make sure that the InternalRegisterClassEx call
* receives the id as a parameter.
* -If in FNID_WNDPROCSTART-END range, make the proper STOCID call in InitFunctionTables.
* -Add proper FNID call in InitFunctionTables.
* -If the class has a client side worker function (pcls->lpfnWorker) or you expect
* apps to send messages to it or call its window proc directly, define
* a message table in kernel\server.c and initialize it in InitMessageTables.
* -If there is a client side for this proc, you probably need to add it to
* PFNCLIENT.
* -Add the debug-only text description of this FNID to in gapszFNID in globals.c
* -See if you need to modify aiClassWow in client\client.c
* -Modify the gaFNIDtoICLS table in kernel\ntstubs.c

===================================================================================
另外user32有两个辅助表用于继续分发消息，比较有意思！
一个是消息表:MessageTable。记的笨笨雄也以前提出来过这个东东！
一个是消息所对应跳转的事件表:gapfnScSendMessage 。
两个表在下面给出：
首先根据消息的ID在MessageTable表取出消息ID所对应的sig,然后与3F相加,
得出的结果是它所对应事件表gapfnScSendMessage的索引然后跳到到它的事件地址中。
随便找个消息分发函数比如：DefWindowProc--->RealDefWindowProc--> RealDefWindowProcWorker，
真正用到MessageTable 索引是到了RealDefWindowProcWorker这个函数中.win2k代码好象没有找到个函数！
这个过程用od跟不错,od跟踪到这里：

77D1B41B 33C9 xor ecx, ecx
77D1B41D 8A8F E814D177 mov cl, byte ptr [edi+77D114E8]---->7D114E8就是MessageTable表，edi是消息ID号！
77D1B423 83E1 3F and ecx, 3F------>运算一下
77D1B426 FF148D E818D177 call dword ptr [ecx*4+77D118E8] ------->77D118E8就是gapfnScSendMessage的地址,ecx*4它的索引！

上面汇编对应的win2k代码()：
pmsg->message >= WM_USER ? (ULONG_PTR)SfnDWORD :
(ULONG_PTR)gapfnScSendMessage[MessageTable[pmsg->message].iFunction];
win2k定义MessageTable表部分如下(message.h)：

NtUserMessageCall是个native api，它又跑到系统核心层去了。其他的fnCBGETEDITSEL，fnIMECONTROL等感兴趣的自己跟或者查看2k代码。
最后给出DefWindowProcWorker关系处理的win消息,感兴趣的可以看看精简了一下：

其他的公共控件见comdlg32等库.敢兴趣的自己鼓捣吧,提供一个小思路,虽然2k代码有点老,不过参考还是很不错!
基本完毕了,没有哈目的,纯熟兴趣!
俺是一只小菜鸟,多谢大家指教!!!
