The TVM_GETVISIBLECOUNT message obtains the number of items that are fully visible in the client window of a tree-view control. You can send this message explicitly, or by using the TreeView_GetVisibleCount macro.

wParam = 0;

lParam = 0;

Return Values

Returns the number of items that are fully visible in the client window of the tree-view control.
