Code Debug Issue

Working with the Head First C# ebook. entered the single line of code in

messageBox.show ( "Contact List 1.0. \nWritten by: Phil Pense", "About") ;

Same line of code was entered in two separate but identical projects. Debug of the first goes to completion and generates the About panel. the second does not generate the About panel. The debug readout is as follows:

I write as a novice and can see no apparent error that would prevent the "About" panel to present itself. IDE image is uploaded to:https://skydrive.live.com/redir?resi...F3F75A51A!1393 Guidance sought

Most likely, the click event for your picture box is not hooked up to the pictureBox1_Click(...) method.
(Provided that there is a picture box on the form.)

This could happen if you entered the code from the book, but didn't follow the steps in detail (or if it wasn't explained in detail).
Normally, you would add a picturebox (or some other control) to your form in the designer, select it, check out it's properties panel, click on the little yellow thunderbolt icon [http://i3.msdn.microsoft.com/dynimg/IC90369.gif] to show it's events, double click the "Click" event in the list, and the IDE would then automatically generate the appropriate handler method, and hook it up.

But, since you already have a method defined, just find the Click event in the properties panel, and open the dropdown next to it - it show's a list of all the compatible methods available; pictureBox1_Click should be shown, select it and you're done.

You'll learn later on that this can be done in code as well.
