Hi There,

working with a treeview, I need to refresh it when the value of another control changes. For that purpose, I clear it simply by MyTreeView.nodes.clear . Then, I repopulate it. However, though any intermediate check on the number of nodes shows that the number of nodes corresponds to my expectations, when the treeview is redisplayed, it has kept the whole history on display as if the clear would impact the counters, but not the actual contents...

(framework 2.0 SP1)

Any idea ?

Found the issue.

Since I develop in VB, I needed to pass a treenode to a function. However, I passed it by reference, rather than by value. It looks like internally I got a pointer of pointer rather than a simple pointer (which is one of the reasons why I am going to move to C# soon to have more direct control over pointers), causing duplicates. Though I am not exactly sure why duplicates appear, fixing the call by passing the treenode by value has fixedit.
