Also, for testing purposes, what numbers do I use in Genuine(X,Y,true/false, true/false) to be able to test for genuine every launch?
Don't check at every launch. IsGenuine() with no parameters will do it. But you shouldn't use that in production.
Whether the application was activated online or off, would like to check if key genuine every x days. If online, do check, if not online, launch program normally. Continue checking every launch for as long as it takes until online and then check if genuine, and reset back to x days. (am using Xojo for development). ie, I don't need a grace period in the normal sense.
No that's not possible because users would just block connections to the activation servers. If you want to do completely offline verification then use IsActivated(). Otherwise use IsGenuine(X, Y, ...)
