I'm trying to get 'acts' and 'acts used' in order to let the customer know Total Activations allowed and used.
That information is not available from the TurboActivate API. You can store that information in custom license fields if you want.
I have looked at limelm.pkey.getDetails but don't know how to implement, or the correct syntax in my vb.net code to get to this information.
You shouldn't use web API in your app. Why? Because you app would need to contain the API Key, which allows anyone full access to your LimeLM account.
Make sense?
