Open Visual Studio 2003 solution

[gushchin]

Hello,

I opened the Visual Studio 2003 solution and need to add a C# file to it.
Is there any ability to add a file so it will appear in the Visual Studio project? Is there any ability for developers to work from the multiple IDEs (Visual Studio and SlickEdit) with the same solution?
If not - how do I suppose to build the solution? Do I need to add a file to the Nant file or something like this?

Thank you!

I'm sorry for distrubing: but I would repeat my question.
Have anyone used the Slickedit with the Visual Studo together?
How do you do it?

Adding files to vcproj's should work. At least it works for me
Just activate 'Projects' toolbar and use the context menu (r-click on it) or use the menu 'Project->Project Properties->...'.
Except a few 'advanced' VS features SE provides good VS solutions/projects (interworking) support.
