VC++ Can't manipulate forms

[f9073341]

I'm running Visual Studio Express 2008 and I'm currently using a Windows Form Application.

I really just want to know how to update my form (.h file) from outside the form (if that makes sense). E.g. Update the text in a text box from a management class outside of the form. Or maybe you can suggest a better design here?

I thought this might be the answer, but I'm not familiar with properties:

Thanks.

I think the main problem is this auto-generated statement in main().

Application::Run(gcnew form1()));

Because it sets up the message loop, I can't seem to interact with the form.
