You're not calling Application.Run in, so your form is never running a
message pump.
In Class1 you're creating a new form, but never displaying it. If you
pass a reference to the current form to the addstatustoo method (as an
extra parameter) and act on that instead, you'll see it works.

Well, if I make it a static method:
public static void addstatus(strin g status)
{
Form1 obj = new Form1();
obj.textBox1.Ap pendText(status + "\r\n\r\n") ;
obj.ShowDialog( );
}
This works, but it displays a new window for everytime I write to it. For
my purposes I need to have the class be able to write to the form - without
having the form pass a reference.

That's fine so long as there's only ever one textbox you need to write
to, but it's very inflexible.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
