NMTVDISPINFO
typedef struct tagNMTVDISPINFO {
    NMHDR hdr; 
    TVITEM item; 
} NMTVDISPINFO, FAR *LPNMTVDISPINFO; 
Contains and receives display information for a tree view item. This structure is identical to the TV_DISPINFO structure, but it has been renamed to follow current naming conventions.
hdr
NMHDR structure that contains information about this notification message.
item
TVITEM structure that identifies and contains information about the tree view item. The mask member of the TVITEM structure specifies which information is being set or retrieved. It can be one or more of the following values:

TVIF_CHILDREN The cChildren member specifies, or is to receive, a value that indicates whether the item has child items.
TVIF_IMAGE The iImage member specifies, or is to receive, the index of the item's nonselected icon in the image list.
TVIF_SELECTEDIMAGE The iSelectedImage member specifies, or is to receive, the index of the item's selected icon in the image list.
TVIF_TEXT The pszText member specifies the new item text or the address of a buffer that is to receive the item text.
If the structure is receiving item text, you typically copy the text to the buffer pointed to by the pszText member of the TVITEM structure. However, you can return a string in the pszText member instead. If you do so, you cannot change or delete the string until the corresponding item text is deleted or until two additional TVN_GETDISPINFO notification messages have been sent.
