You could always paste it on Rafb and leave whether it is too big or not up to the discretion of the person helping you.

People aren't going to get a lot out of semi-cryptic messages from the console when they don't have the code in front of them. And also, are you building in Debug mode on purpose?

well, it seems you're declaring the event receiver twice...
look at the first both messages:

Code: Select all

they tell you pretty well what you did wrong and where and what you should do... ;)

Never include cpp files is a good hint.

It's MastEventReceiver not MastEventReciever.

I'm not talking about the filename, but about the classname. Which you probably copy&pasted, so I guess it's still MastEventReceiver and therefore your variable using an unknown class MastEventReciever.
