    [RESOLVED] InitializeComponent Error

    I have been fixing up code that I wrote years ago before I knew what I was doing. I have mostly just changed syntax for variables and changed many Public functions to Friend.

    After completed this maintenance I now get a "object reference not set to instance of an object" error when I try to open a form at the InitializeComponent line of it's New sub. This doesn't happen at start up - only when I click a button to open a different form.

    I must have changed something I shouldn't have. I get this error whenever I forget to use the new keyword but I'm not sure how this applies to InitializeComponent().

    I copied the Call Stack which I really have never deciphered before so go easy on me please. Thanks in advance.


    Code:
    System.NullReferenceException was unhandled
      Message=Object reference not set to an instance of an object.
