Three ways you can do this – from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol – this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load from the dropdown.
A second way to do it is programmatically – somewhere (constructor maybe) you’d need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);
A third way using the designer (probably the quickest) – when you create a new form, double click on the middle of it on it in design mode. It’ll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you’re good to go!
