Click on the "Publish Project" toolbar button and if you keep your eye on the output frame you'll notice the automatically incremented publish version value.

Changing your perspective back to that of the user, use the Windows Start menu to run the example application again. Your application has transparently downloaded the application's manifest and detected that there is a new version available. You, the user, see a notification window displaying that a new version of the application is available. Click OK to download and install the update.

Open the "About" window and there you are. You'll see that the static text control's background color is now green, the "G" or second in our RGB sequence. You'll also note that the application's Start menu shortcut's values have changed if you've taken advantage of that option. For the sake of the next section of this article, leave the application running and return to the PowerBuilder IDE.

The Update Notifier Feature
How this feature manifests itself to the user is two fold. At runtime it consists of a pop-up window originating from the system tray that notifies the user of various application update status conditions, as well as a pop-up menu that enables the user to take certain actions and modify certain options that concern updates to their application.

In the PowerBuilder 11 IDE, change the background color of the static text control on w_mss_about to the blue in our RGB sequence. Save and close w_mss_about. I'll also navigate to the Notify tabpage of my WinForm project and choose to use a non-default background image for my Notifier window. When you choose to use non-default values, the display size of Notifier's icon is 16x16 and the display size of background image I've used is 148x120. I'll also change the Notifier window's title value to "MSS." Publish your application once more, and then activate the running instance of it once the Publish is complete.
