Licensing a component without a user interface at design / compile time

[Neil Davidson]

We have a component without a user interface which we want to license
at design time.

If someone has a design-time license then they should be able to
compile applications using the component, but if they do not have a
design time license then they should not be able to do this.

The component does not have a user interface so its constructor is
never called at design- or compile- time. The LicenseProvider
attribute does not seem to work in this case.

Is there any way to do this?

Thanks,

Neil

Hi Neil,

Did you component inherit from System.ComponentModel.Component? Based on my
test, its New method will be executed when we add it to a form at design
time. Therefore, we can add the license validating code here.

Thanks for the reply. The component has no UI so it isn't added to the form
at design time.

I figured out what the problem was eventually though; I didn't understand
the role of the licenses.licx and didn't realize I needed to create it
manually. Once I'd done that it worked fine.
