wParam = 0;
lParam = (LPARAM) (const TV_ITEM FAR*) pitem;
Parameters
pitem
Pointer to a TV_ITEM structure that contains the new item attributes. The hItem member identifies the item, and the mask member specifies which attributes to set.
If mask specifies the TVIF_TEXT value, the pszText member is the pointer to a null-terminated string and the cchTextMax member is ignored.
If mask specifies the TVIF_STATE value, the stateMask member indicates which item states to change and the state member contains the values for those states.
Return Values
Returns zero if successful or -1 otherwise.
