TVM_SELECTITEM Selects the specified tree-view item, scrolls the item into view, or redraws the item in the style used to indicate the target of a drag-and-drop operation. You can send this message explicitly or by using the TreeView_Select, TreeView_SelectItem, or TreeView_SelectDropTarget macro. TVM_SELECTITEM wParam = (WPARAM) flag; lParam = (LPARAM) (HTREEITEM) hitem; Parameters flag Action flag. This parameter can be one of the following values: TVGN_CARET Sets the selection to the specified item. The tree-view control's parent window receives the TVN_SELCHANGING and TVN_SELCHANGED notification messages. TVGN_DROPHILITE Redraws the specified item in the style used to indicate the target of a drag-and-drop operation. TVGN_FIRSTVISIBLE Ensures that the specified item is visible, and, if possible, displays it at the top of the control's window. Tree-view controls display as many items as will fit in the window. If the specified item is near the bottom of the control's hierarchy of items, it might not become the first visible item, depending on how many items fit in the window. hitem Handle to an item. If hitem is NULL, the control is set to have no selected item. Return Values Returns TRUE if successful, or FALSE otherwise. Res If the specified item is the child of a collapsed parent item, the parent's list of child items is expanded to reveal the specified item. In this case, the control's parent window receives the TVN_ITEMEXPANDING and TVN_ITEMEXPANDED notification messages. Using the TreeView_SelectItem macro is equivalent to sending the TVM_SELECTITEM message with flag set to the TVGN_CARET value. Using the TreeView_SelectDropTarget macro is equivalent to sending the TVM_SELECTITEM message with flag set to the TVGN_DROPHILITE value. Using TreeView_SelectSetFirstVisible is equivalent to sending the TVM_SELECTITEM message with flag set to the TVGN_FIRSTVISIBLE value.
