I have an add-in I'm developing that basically analyzes multiple projects'
codemodels in a solution.
It has a tree view and when you double-click a node representing a
codeelement, it should open the containing document of the codeelement and
navigate to the line and position it starts at. How can I determine the
codeelement, given some basic information? I don't mind iterating until I
do/don't find my item. I would just like an idea where to start.

Given the following string:
TestHGrid: M:TestHGrid.TestIHGrid.#ctor(System.Drawing.Color)

I know that this is in the project TestHGrid. Can I reference that project
using:
Dim proj As Project = Me._applicationObject.Solutions.Item("TestHGrid")
? Will that give me a reference to the project I want, or do I have to
iterate?

What if there are two projects named TestHGrid in my solution? Hadn't
thought of that until just now.

I know that this method is a constructor (In VB.Net, Sub New()) that takes a
single Color object as a parameter.
I know that it has two parent objects, TestIHGrid and TestHgrid,
respectively, which could be namespaces, classes, interfaces, modules, etc
(which I don't definitively know).

Should I just iterate over the codemodel eleemts looking for matches by name
(which if anything is overloaded, could produce duplicates), or is there a
more intuitive way?

Once I know the codeelement, it is easy enough to get the StartPoint. How do
I navigate to it, once I have that?

Any help is appreciarted.
Thanks in advance.
