Some times when developing Windows Mobile Application you might want to make sure that users cannot navigate to and use any of the other programs except your program . This means that the windows start button in the taskbar must be disabled .
There are some predefined functions in the coredll.dll in Windows Mobile
<DllImport("coredll.dll")> _ Public Shared Function FindWindow(ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr End Function <DllImport("coredll.dll")> _ Public Shared Function ShowWindow(ByVal hWnd As IntPtr, ByVal visible As Integer) As IntPtr End Function
To Disable the Start Button , you can use
ShowWindow(FindWindow("HHTaskBar", Nothing), 0)
Note the HHTaskBar . This is a windows handle for the task bar , but when we hide this , this will hide the entire window along with the X button .
Instead , you can use the EnableWindow function with false as parameter to disable the window rather than hiding it or even the function SHFullScreen with the parameter ( SHFS_SHOWTASKBAR , SHFS_HIDETASKBAR,SHFS_SHOWSIPBUTTON,SHFS_HIDESIPBUTTON,SHFS_SHOWSTARTICON , SHFS_HIDESTARTICON ) .
Some times this might be more troublesome , if you want to disable the same on the other programs too like Calculator etc …but still enable the X button .
Here’s a simple Kiosk Mode Library that i found was simple and easy to use from the Windows CE Programming Blog
The functions are implemented in a Dll file (StartLock.dll) that is written using Embedded Visual C++ 4.0 , which means the functions are accessible from any managed language code like VB.NET / C# .
Simple isn’t it ?.
The list of functions supported by the library includes .
You can find more information on downloading and using the library in the Windows CE Programming’s
