I'm working on an application that has the user open a calendar view, and schedule different tasks (similar to what you can do in outlook). I have the Calendar view, but don't know where to go from here. This is borrowed code btw. I've updated some of it to meet some of my intent.
I'm thinking of using mysql as the database to store the task dates, but how do I populate my calendar with the dates from the database? I've attached the borrowed code. Any suggestions are welcome...
