Syntax
Parameters
flag
Action flag. It is one of the following values:
| Value | Description |
| 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
TRUE indicates success. FALSE indicates failure.
Remarks
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.
