I can't quite see your point not to use reflection. Reflection is VERY fast,
especially compared to the time needed to actually show a form. The
framework uses it all the time, probably without you even noticing. Also, if
you're using Reflection on your own assemblies, there shouldn't be a problem
with any restrictions. And I guess that VB6 also uses some internal
reflection algorithm if you do f = Forms("frmMain").
So if you want to give Reflection a try, do something like this (assuming
the form to display is in the same assembly):
Dim ty As Type =
System.Reflection.Assembly.GetExecutingAssembly.GetType("frmMain")
Dim f As System.Windows.Forms.Form = Activator.CreateInstance(ty)
f.Show()

Been under the impression that you incur some extra overhead that can
slow things down. Probably inconsequential in this circumstance I know.
Reflection would be convenient, but I don't want to get lazy and start
reflecting everything. Also, I will eventually need to implement some
restrictions on the app (similar to the current thread about allowing
the assembly to be used only from a specific exe) and am concerned that
I'll put myself behind the proverbial 8-ball when those restrictions are
implemented.

I am not sure if this is available, but I wondered why you want to avoid
reflection? That seems like the natural case for solving this.
Thanks,
