To check if a referenced class object is already active or not

MyFriendPM asked:

Open original thread
I have two windows application projects. I referenced one of the project in the other project and created an instance(object) for the referenced project class.

First project is referenced in the second project.

Scenario:
Second project is my start-up project. When I click a button in my second project, the first project's form will get opened [ obj1.show(); ]. So at this point of time, both the forms will be active.

Question:
When I click another button in the second project's form, is there a possibility to check if my first project's form is already open or closed ?

Kindly help me out.
