nsKeyHook plug-in
Wrote this small plug-in so I could validate input of a product key in a client's installer. They've let me release it 🙂. You can handle WM_CHAR for example to only allow alphanumeric input and WM_PASTE to only allow paste of alphanumeric text. You can also handle WM_PASTE to automatically fill all product key fields (e.g. 5 text boxes for a 25 character product key).
