Default Form in a DLL file for VB6

  Hi there . . .
  I´m trying to create a simple DLL in VB, but it have to contain a FORM (simple one) and I have to call this form from the EXE (also in VB).

  . . . is there some one here who can help me ?
  (a simple code example will be welcome)

The way I do this is to have a method on a public class (for example, a class whose Instancing is set to Multiuse).
The purpose of this method is to instantiate the form and display it.

For example - this method is on the public class named Class1 in the Dll project (Project2.Class1) - this assumes you have a form named Form1 in the Project2 project:

Public Sub ShowForm()
    Dim f As Form1
    Set f = New Form1
    f.Show vbModal
End Sub

You call it from the Exe like so (assuming you are referencing Project2):

Private Sub Command1_Click()
Dim c As Project2.class1
Set c = New Project2.class1
End Sub

I hope that helps

In vb.net I can add a assembly to call the sub from the dll. How can I do this from vb6?
If I use:
Declare Auto Sub ShowTestForm Lib "FormInDll.dll" Alias "ShowTestForm" ()
I get an error like this:
Unable to find an entry point named 'ShowTestForm' in DLL 'FormInDll.dll'.
