_T是什么意思，另外还有TV_DISPINFO结构，msdn中怎么没有

[cnfire]

_T 是一个宏，用来把字符串常量字符设置为中性

[weakpig]

The _T macro is used to maintain compatibility between different string representations, and it must be used for all literal strings in an ActiveX control project.

typedef struct _TV_DISPINFO{
NMHDR hdr;
TV_ITEM item;
}TV_DISPINFO;

其中
typedef struct _TV_ITEM{ tvi
UINT mask;
HTREEITEM hItem;
UINT state;
UINT stateMask;
LPSTR pszText;
int cchTextMax;
int iImage;
int iSelectedImage;
int cChildren;
LPARAM lParam;
}TV_ITEM, FAR *LPTV_ITEM;
