I want to calculate the virtual path of a file included in a visual
studio .net project. But unfortunately i'm only able to get the
physical pathname of the project item.
At the moment i recursivly search the project tree from top to bottom
until i find the projitem object. At the same time the path is
generated - but this is very slow for large projects.
Starting from the projectitem object, is there any possibility to go
upwards in the project tree until the project root is reached?

Thanks, Manfred

Yeah, but since i need to construct the virtual path I'll need the
predecessor of a projectitem in the project tree.

Yes, given a ProjectItem, ProjectItem.Collection returns the ProjectItems
collection it belongs to (do not confuse with ProjectItem.ProjectItems,
which is the collection of children), and then ProjectItems.Parent returns
the object parent , which can be a Project (you are done) or a ProjectItem
(such a folder, or a file which depends on, etc.). In the later case you
enter in recursion, etc.

Thanks for your help, but there is still a problem. As you mentioned,
ProjectItem.Collection returns the ProjectItems collection it belongs
to. But unfortunately this may not be the parent ProjectItem.

e.g. I need to calculate the virtual path to the selected project item
and therefore i retrieve my ProjectItems this way:

Dim proj as ProjectItem
Dim item As SelectedItem

For Each item In DTE.SelectedItems

proj = item.ProjectItem
...

Next

I have tried this, but the proj.Collection.Parent points to the DTE
object, not to the predecessor of the current ProjectItem in the tree.

Manfred

Hummm, interesting. It could be because you are getting the ProjectItem from
the DTE.SelectedItems collection, because if you get it from the
Solution.Projects, Project.ProjectItems, etc. it should work fine. Not sure
it this will work, but you could try to retrieve a ProjectItem whose parents
are more meaningful using:

myProjectItem = DTE.Solution.FindProjectItem(item.ProjectItem.FileNames(0))'

That is, FindProjectItem retrieves a ProjectItem from the solution given its
file name. Hopefully its parents are correct this time.

If've tested the code above but it seems that it doesn't work either
because when i retrieve my ProjectItem with the
Solution.FindProjectItem method, the myProjectItem.Collection property
is always nothing.
