Custom Class Library

[Guest]

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.
