Well, I think I know what you're going for. With, for example, the Treeview control, you can get an object reference through the key that uniquely defines the node. Something like
oNode = ThisForm.Treeview1.Nodes(ThisForm.cKey)
where ThisForm.cKey holds a string with the key. Unfortunately, the Controls collection can't be similarly referenced. However, if you stored the numeric value as a property of the form you could.
