In the first part of this series I showed how to make your compact framework application full screen or remove the Start icon from the menu bar. Now we will take a look at the task bar.
The task bar is at the top of your screen (except for fullscreen applications) and shows valuable information like the connection status, battery status or the current time.
Not full screen, taskbar not locked
This is a kiosk mode risk. The user is able to click the symbols in the taskbar and gets a popup menu with some icons. These icons enable the user to change connection settings, power management settings and others. You propably do not want to allow the user to make changes to some or all of the possible changes.
For example, clicking on the phone or signal strength icon will bring up this dialog:

I would like to start a series of articles of how you can lockdown your application user in your application. How can you achieve a kiosk mode application, where the user is only allowed to do what you define.
The first article is about the Windows Start and Done Icon in menu bar and about fullscreen. You may already know, how to hide the start and done icon permanently from a Windows Embedded Handheld (Windows Mobile 6.5.3) device: Link
But there is also a temporary way using the same approach. The trick is to change the registry keys, that make the OS believe you have hardware buttons for Start and Done, BEFORE you show your CSharp form.
Before Windows Embedded Handheld (WEH, or Windows Mobile 6.5.3), you are able to use SHFullScreen API calls. But this will not work with WEH. Neither the flags SHFS_HIDESIPBUTTON nor SHFS_HIDESTARTICON will work. The LockDown.cs class also includes code for that and you may test the functions with the Test-Application.
The class I am talking about is called LockDown. There is also a Test-Application (OEMTitleBarHandler, dont ask me about the name selection) to test all functions I will describe.
