vb.net 2010 desktop application and dropdown list boxes

Question

I am asking this question since this is the first time that I have been asked to work on a vb.net 2010 desktop application.

I have  been asked to accomplish the following tasks:

1. Add a dropdown list box to ask the user what vendor they want to work with. There will be a default vendor always selected.

2. Add a dropdown list box to ask the user what access 2013 database file they would like to work with. A default Access 2013 name will be in the dropdown list box.

 

Thus can you tell me how to accomplish this goal and/or point me to urls (links) that will tell me how to complete the complete these requests?
