This very simple function will handle all Checkboxes (parents & childs) of a TreeView control.
If you click a child node it will check all parents of this node. Also, if you "uncheck" a child node when nomore nodes are checked on the same hierarchy, this code will auto uncheck all the parents.
Simple function. Recursive calls.
The code encapsulated in a separated .BAS.
Only add this .BAS in your project and enjoy.
If you have any doubts, please let me know.
Sorry by the horrible english...
