Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
I don't really know what you mean by get the outlet. An outlet is just a pointer to an object and the sender variable is already a pointer to the button so...
And I don't really know how to help you create non repetitive code unless I know exactly what you plan to do. Maybe post 2 examples of what you would put in the if statement?
