The TVM_SETITEM message sets some or all of a tree-view item's attributes. You can send this message explicitly or by using the TreeView_SetItem macro.

Syntax

        lResult = SendMessage(     // returns LRESULT in lResult
        (HWND) hWndControl,        // handle to destination control
        (UINT) TVM_SETITEM,        // message ID
        (WPARAM) wParam,           // = 0; not used, must be zero
        (LPARAM) lParam            // = (LPARAM) (const LPTVITEM) pitem
		
        - Version 4.71 and later -
		
        (WPARAM) wParam,           // = 0; not used, must be zero
        (LPARAM) lParam            // = (LPARAM) (const LPTVITEMEX) pitem
		
   );

Parameters

pitem

Pointer to a TVITEM structure that contains the new item attributes. With version 4.71 and later, you can use a TVITEMEX structure instead.

Return Value

Returns TRUE if successful, or FALSE otherwise.

Remarks

The hItem member of the TVITEM or TVITEMEX structure identifies the item, and the mask member specifies which attributes to set.
