用WindowsAPI封装绘图窗口类，如何从窗口消息值转成可读消息字符串，Win32窗口生命周期消息

最近在写一个纯win32api方式创建窗口的绘图类的封装（摆脱mfc的束缚）。
从对win32api方式生成一个窗口过程中，观察窗口过程函数接受了哪些消息，了解窗口生命周期更深刻的认识。

第一步：实现实现一个windows消息id值到以"WM_"开头的可读的windows消息名字符串的转换函数（该函数由WinDef.h头文件制作而成），
代码如下：

C++ Code

//全局函数：取得windows消息码所对应的消息定义字符串，Release模式下返回一行表述函数已弃用的提示字符串，而不是NULL指针。
LPCTSTR GetWindowsMsgStringFromMsgID(UINT messageId){
#ifdef _DEBUG
#define ITERN_WNDDOWSMSGID2STRING( szName , nID ) case (nID):return _T(#szName);break
switch(messageId){
ITERN_WNDDOWSMSGID2STRING( WM_NULL                         , 0x0000
