    uniquely identifying TreeNodes

    I need to be able to identify a TreeNode in a TreeView uniquely so that I can get the TreeNode only by knowing the unique value. I tried to use the TreeNode.Index property but that is only unique to the TreeNode list that it is in (it doesn't take into consideration parent nodes, etc). Does anyone have an idea on how I can do this?

    Set the Tag-attribute to something unique, like an integer that is constantly increased for each node, possibly reusing old indexes if nodes are removed? Perhaps use the "pointer" value of the node itself (dunno how accurate this is)?

    ahh ok didn't think of the tag idea there. I am currently using the HWND and it appears to work. Only thing that I can so go wrong there is if anouther peice of code removes the treenode, like unmanaged code. I doubt that'll happen though, and if it does I didn't do it.
