In a WinForms app, how to implement the analog of global variables in a VB6
app ?

You should really, really avoid global variables, they are bad(TM).

If you have no other option, create a class with static properties/fields
for each variable you need. For good measure, declare a private constructor
so the class cannot be instantiated.

Everything John said is sensible - although IMHO there are definitely times
when global variables make sense.

But, as evil as it may be, one can still implement a VB Module, which is
roughly the equivalent of a VB6 "General" or BAS module.

It appears that the way .NET treats these is essentially what John
recommends to do - it creates a static (or Shared in VB) entity - which
looks an awful lot like a class - where all routines are automatically also
shared.

Anyone know exactly what a VB Module is ?

Anyway, that is one way to implement global members.

Sorry - got the names swapped - John asked the original question - it was
Peter that offered a response! Duh!

So, Everything PETER said is sensible ... etc ...

Since I don't know very little about VB your suggestion might be a lot
better than mine.
