BlitzPlusEXT DLL adds new commands

GadgetHidden(gadget)
Returns True if the gadget is hidden, otherwise False.

GetTreeViewNode(node,index)
Returns the child of the indicated tree view node. Use this to sort through tree views recursively:

For n=1 to CountTreeViewNodes(root)
	node=GetTreeViewNode(root,n)
	Next

I wouldn't charge for it, but I spent two days figuring this stuff out.

Buy the DLL.
