You can't unblock them?

Well, I don't really use VB, so I don't know how to add a Flash control to a form. However, there is indeed a way to do it, there have been countless programs that do that. The whole sending keys thing is kind of unclear to me if it can be done without the Flash Control being in focus. I don't understand why you don't want it to be in focus. The thing is that what reads the key input would be the Flash client (the flash control), and it can only read inputs if it's in focus. You can probably force it to be in focus whenever you need to send keys, I'm sure the Flash Control has to have a property to set it in focus.
