Custom Class Library

I would like to create an add-in with one or more custom classes. Then, as long as the add-in is loaded, I would like to be able to create objects of type "custom class" (as defined in the add-in) witin other workbooks. Is this possible?

This is a tricky one and something which took me ages to work out when trying this before.

In your add-in add a function like this in a standard module:-

Public Function ReturnClass() As ProjectName.Class1
Set ReturnClass = New Class1
End Function


Where ProjectName is the name of your add-in as specified in the Properties window when you select the add-in.

Now, in the workbook where you want to use the classes try this:-

Select a reference to the add-in from Tools, References. Then you'll be able to do this:-

Dim c As ProjectName.Class1

Sub test()
Set c = ProjectName.ReturnClass
c.DoSomething
End Sub

I don't believe you can directly create classes defined in another project, but this seems to work well enough. Please let me know if something is unclear.

Thank you very much for taking the time to help me out. I will give this a try.
