This message changes the text of a list-view item or subitem. You can send this message explicitly or by using the ListView_SetItemText macro.
LVM_SETITEMTEXT wParam = (WPARAM)(int) i; lParam = (LPARAM)(LVITEM FAR *) pitem;
Index of the list-view item.
Pointer to an LVITEM structure. The iSubItem member is the index of the subitem, or it can be zero to set the item label. The pszText member is the address of a null-terminated string containing the new text; it can also be NULL.
The pszText member can also be LPSTR_TEXTCALLBACK to indicate a callback item for which the parent window stores the text. In this case, the list-view control sends the parent an LVN_GETDISPINFO message when it needs the text.
