My application will start (dataset filtered by username/date) and if it's the first time the user has used it today it will be a blank entry form because there is no record for today created. The user can just type data into the blank form and close it. On the form closing event I want it to run a tableadapter.insert(username, date, x,x,x).
If it starts a second time it will load showing today's entry because today's date was inserted previously when they closed the form. So this time when they close the form I want the form closing event to just run a tableadapter.updateall(dataset) command. I need some help with my form closing event...
