Tree View Nodes

[campbere]

Can someone help explain the following code? I know that the Mid is evaluating Node.key starting at position 1 and ending at 1 but what is Node.key? I know that nodes make up a tree view but I dont know where the key falls into place.

If Mid(Node.key, 1, 1) = "#" And Has_data = True Then
num = Int(Mid(Node.key, 2))

Thanks,


campbere

A treeview's contents is a collection of Node objects. They can be accessed via the Treeview1.Nodes colelction. Each node can be given a unique key (String) with helps identify which node the user clicks. The code extract you poste does just that by checking o see if the first character of the current node's key has a hash mark in in. Maybe the original programmer used a Hash mark to denote the level that this node resides in the tree....
