adding to Tim's reply,

Thing is... you can have several instances of a class. That means you
need to be specific about the instance you're trying to use.

I'm not sure how your dll's put together but it probably starts with a
class that loads the forms. If you're not doing so already, those forms
should be created using object variables instead of writing something
like Form1.Show since there may be several instances of your main class
running as well.... anyway, your form needs a reference to the class you
want to use so you'll need something that looks a little like....

Private Sub Form_Load()
Dim o As Class1
Dim i As Integer

Set o = New Class1
i = o.TheNameOfYourFunction

Note that, if the name of your function doesn't show in intellisense
when you hit the period after the "o" above, there's a problem somewhere.

Also note that you should declare the function as Friend unless you plan
to use it from outside of the DLL. If you declare it Public, you won't
be able to change anything about its interface (name/args/etc) without
breaking Binary Compatibility... if you break, you'll have to rebuild
any apps that use the DLL.
