/**
通用控件 需要捕获notify消息
WM_NOTIFY 消息
当事件发生或控件需要一些信息时，由公共控件发送到其父窗口。
参数
wParam
发送消息的公共控件的标识符。 不保证此标识符是唯一的。
应用程序应使用 NMHDR 结构的 hwndFrom 或 idFrom 成员 (作为 lParam 参数传递) 来标识控件。
lParam
指向包含通知代码和其他信息的 NMHDR 结构的指针。 对于某些通知消息，此参数指向将 NMHDR 
结构作为其第一个成员的较大结构。扩展：获取更详细的列表通知信息 LVM_GETITEMTEXTW
当通知码是LVN_xxx（列表专属）时，lParam可强转为NMLISTVIEW结构体（包含项索引、列索引、状态等）：
typedef struct tagNMLISTVIEW {NMHDR   hdr;        // 基础NMHDR结构体int     iItem;      // 项索引（-1表示无）int     iSubItem;   // 列索引UINT    uNewState;  // 新状态UINT    uOldState;  // 旧状态UINT    uChanged;   // 变化的状态类型POINT   ptAction;   // 操作的坐标LPARAM  lParam;     // 项关联的自定义数据
} NMLISTVIEW, *LPNMLISTVIEW;
