hey guys
is there a way to close a wxMessageBox with an external input  (like input 0 for example?)
i use it as a warning message for the user when a safety door is open and i want it to go away once it's closed.
thanks!

in the screen plc code read the state of the input and generate the message.. make sure you keep track and only do on a transition so it doesn't generate the message every scan.. and simply either lockup Mach4, crash or both. 

my mistake.. not sufficient coffee this morning... no.. I don't see any method to close a message box using an input.. why don't you simply write into the bottom message banner when the guard is open.. you can clear that from the plc script.. or put a box on the screen and then make it invisible. Or you could do something really crazed and try to stuff keystrokes into the keyboard buffer to clear the box.. now that would be something to post!!! 

Hey. Thanks for taking the time to reply.
That's what I thought, but was hoping for someone to have a better idea... 

and while this would be beyond my really truly meager capabilities.. I guess you could somehow retrieve the message box instance itself (or its thread or whatever id or position in the Ether it holds) and kill that in code.. way past anything I would attempt myself.
