I want to write a Add-In for the development enviroment: "Microsoft Visual Basic for Applications" which I have to use.
I want to add some convenience functions.
Unfortunately I cant find anything about this because as soon as I search for "Microsoft Visual Basic for Applications" or "Add-In" it tells me how to write Add-in with VBA. But I want to know how I write a Add-In in any language (if possible everything else but vba) for the development enviroment: "Microsoft Visual Basic for Applications"
