I think you are trying to mix C# and VB.Net. In VB you access application settings using My.Settings, and the form closing event is declared like this]

VB

Private Sub Form1_FormClosing(sender As System.Object, e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing

    End Sub

You also don't say how your user is creating new items to enter into the combo box, and what method is used to save these temporarily, before closing the form.

Solution 2

What is or should properties be?
As its looking for an object or variable called properties

Are you developing something in XNA? as a quick Google shows that this is used heavily in XNA.
