how to access existing solution directory in project template wizard

Hi,

I had project template with wizard and is working fine.

My problem is that I have to display all the projects,Classes and Methods from the solution to which we are going to add project template(Right Click Solution->Add New Project->My Own Project Template) in project template wizard(Windows form) as like Unit Test Wizard in Visual Studio 2010.

If I am able to access the directory of solution to which we are going to add project template in wizard then also it's ok for me.

Kindly suggest the solution.

Thanks and Regards,

Ganesh Gidde.
