Help disableling buttons after update (1 Viewer)

I need help with the attached MS task database, i want to do the flowing:

Once a task is created, i want the following fields on the "Task Details" to be disable and not enable unless a new Task is created.

Task Title, Assigned to, Priority and download date: i want these fields to be lock and the downloaded button to be disable for this task after "Close" button is click.

then when a user opens the task i want the user to only be able to modified: % complete, status, and check in and Check In button.

once the user clicks Check In i want to form to close automatically and the check in button to be disable for this task.

then when the user comes back to this task i want the user to only be able to modify "% completed, Status and Check out button", when the user click Check Out, to lock the 'Check Out" button and the form to close automatically.
hopefully someone can help me.

i attached a copy of the database

I would recommend using the Form's On Current event and VBA code to enable/disable the buttons and controls as needed.


or this is how I do it:


Both examples give the exact same results. The first one is easy to understand when learning VBA. The second one is very optimized.
