How do I block all short cut keys or Alt-F4 using vba Excel User Form?

[milankanbi]

Ok I have created a secure login in excel. so I have used a User form- for the user interface and two modules - One for opening the user form when excel loads, the other to remove the close button using Microsoft api. These two modules are successful in terms of security for the client. However, I have encountered a way of bypassing the user form with the simple ALT + F4 Key, and this risk I cannot allow. So, how would I remove/disable the ALT+F4 KEY or even better remove/disable all short cut keys temporally while the user is logging in.

In VBA Programming language NOT Macro please.

Thanks

This will block Alt+f4 (as well as X - easier than API!)
