WPF app won't run in kiosk mode

I have a WPF application that is designed for a touchscreen kiosk. Users will not have access to a keyboard or mouse. The application runs fine when started normally from the program icon in windows. However, when it is set up to run automatically at startup (by replacing the Windows shell using a registry key), the application does not function properly.

The application reads an XML file that lists available videos, then displays buttons to show the videos. When run in "kiosk mode," it does not seem to have access to the files in its media directory (the XML file and presumably the videos as well). I suspect that because the application is running in place of the windows explorer, it is missing resources it needs for file access that are normally loaded by windows explorer.

I have not been able to find any info on this -开发者_如何转开发 there is plenty of info on how to get an app to run at startup, but not much on how to make sure it will actually function in that environment. The PC is running Windows 7 Professional.

Is my assumption about the problem correct, or is it likely something else (e.g. permissions - we checked the permissions, but maybe they operate differently when you replace the windows shell?) If it is because needed resources are not loaded, does anyone have pointers on how to make sure my app loads them?

Perhaps you have file access occurring via a file dialog? This might explain a bit further. What is the minimum functionality needed to create Shell Replacement for Windows?

because you have stopped windows default running explorer.exe , your program can not get access to default xml directory therefore you should specify the complete path for example like below:

stream = File.Open(@"C:\x86\Debug\xml.xml", FileMode.OpenOrCreate);
