Can u tell me how toset a reminder in a calendar and it should show out as a popup notification two hours before the event to occur.
I see problems with your post. First you ask for a "Calendar Even" then later it becomes an event. Another typo in "toset." As a programmer typos can really upset your web pages and code. Try to take time to craft your post and be clear about the title and content.
Finally you did well to add the tags, get in the right forum but then didn't share what you have so far and tell where you are stuck.
