When using a macro or add-in in VS 2005 to iterate the nodes of the Solution Explorer, some nodes inside solution folders are not returned if you didn't expand them previously by hand.

+1 for this as bug. This issue causes serious problems when developing VS addins. If this is by design, then this design is flawed and should be really reconsidered.

Actually I submitted (or was going to submit) a similar issue by myself, and I'm very surprised to learn that this behavior is considered 'by design'. What happens is that a specific API (UIHierarchyItems) Visual Studio exposes simply doesn't work as one can reasonably expect it to. Is it by design? If it is, please reconsider this design. For whatever reason it works the current way, any 'normal' external user / extender will think this is a BUG.

By design? Do they realize that the Expanded = true doesn't WORK!? I can't wait for this to be fixed. IT IS A BUG!

You could try to implement a fix this way:

- For each node, use a flag that indicates if the children nodes have been retrieved or not.
- When the user expands a node, change the flag.
- When the nodes are iterated recursively, if the flag indicates that the children nodes were not retrieved previously, then retrieve them (without expanding the node!).

I know that the current behavior is by design, but it is a bad design, a lazy one, it did not happen in previous VS versions and it does not help at all, it causes problems in addins...

Thanks for reporting this issue. This is actually By Design since the hierarchy doesn't know about the children until the nodes are explicitly expanded.
