TVM_ENSUREVISIBLE  5K3LS3 

The TVM_ENSUREVISIBLE message ensures that a tree-view item is visible, expanding the parent item or scrolling the tree-view control, if necessary. You can send this message explicitly or by using the TreeView_EnsureVisible_321YM macro.

TVM_ENSUREVISIBLE

wParam = 0;

lParam = (LPARAM) (HTREEITEM) hitem;

Parameters

hitem

Handle to the item.

Return Values

Returns TRUE if the system scrolled the items in the tree-view control to ensure that the specified item is visible. Otherwise, the message returns FALSE.

Remarks

If the TVM_ENSUREVISIBLE message expands the parent item, the parent window receives the TVN_ITEMEXPANDING and TVN_ITEMEXPANDED notification messages.
