Hi I was wondering is there a preexisting piece of software (free or paid) that would allow people attending an event to browse content like photos, pdfs and video on a touchscreen. It needs to prevent them from clicking off the filebrowser onto the desktop etc.
I tried modifying the homescreen on a lenovo touchscreen running windows 8 but it doesn't seem very intuitive to people who have never used windows 8 before.

We have implemented a tablet-based application using Oracle MAF. The application runs on Windows UWP. When it was rolled out last year, it has been working fine until the customers upgraded Windows UWP on their laptops to Windows Anniversary edition. After some investigation, We found the following issues:
When user clicks on input text fields in a popup dialogue, the
application randomly crashes (not always but frequently).
When user clicks on input text fields in a normal window (i.e. not in a popup dialogue), and if the screen resolution is scaled (e.g. 150%), the
application also randomly crashes.
When screen resolution is not scaled (i.e. 100%), clicking on input text fields in a normal window
does not seem to cause crash. However, clicking on input text fields
in a popup dialogue can still cause crash.
We could not find any useful/relevant info in Windows log or in our application log.
We have also tested our application with the latest Windows Creator Edition and MAF 2.4.1, we found that the chances of random crashing seemed to have decreased, but crashing could still happen.
We have checked the Oracle MAF certification information at http://www.oracle.com/technetwork/developer-tools/maf/documentation/maf241certmatrix-3746359.html.
It states that "Any tablet or desktop running Windows 10 with Intel processor" are supported. Our customers' laptop specs are:
Lenovo Yoga with Intel Core i5 processor;
Windows 10 Anniversary Edition;
Full High Resolution screen (1920x1080)
Therefore, we believe the customer laptops provide certified runtime environment for MAF applications.
We have researched various technical forums. There seems to be little information about using MAF under Windows UWP environment.
Because our application has been used in production, and the customer corporate mandate is to use Windows 10 Anniversary edition, the customer expressed grave concerns to us for choosing MAF as the mobile platform technology, and we are now under enormous pressure to fix this issue. Any suggestions and pointers will be highly appreciated.
If you can create a reusable test case, my recommendation to you is to lodge a Service Request with Oracle Support so Oracle's development teams can look at this.
We have done further investigation on the issue "input text field causing crash on Windows 10 Anniversary Edition". This time we used the demo CompGallery application from Oracle. We navigated to the "text box" tab, clicked on the text box in "outside a form", entered some text, then clicked on "inside a form" text box. The application crashed (or repeat the above sequence a couple of times on Windows Creator Edition, the application would crash). Note by using "tab" key or screen tapping to navigate between input text fields, we can avoid crashing. With extra clicks on different input text fields before entering text, we can avoid crashing as well.
The CompGallery screen is shown below:
We then looked at the Windows log, not much details were revealed. It contains an event related to the failure of edgethtml.dll, as shown in the screenshot below.
I have a desktop application for my telephone which launches a call on selection+ctrl+left click on any proper telephone number that appears in my desktop, by opening that application. I wanted to do similar functionality for Windows 8 store application. Is that possible?

I think the functionality you're after would be closest to a secondary tile. Have a look here for a sample.
After Googling for about the past hour and a half, I have been unable to find out any definitive information on how the start menu and how windows 8 style applications work behind the scenes. I was under the impression that Windows 8 Style applications were processes which created fullscreen windows and that the Windows 8 start menu was created by explorer.exe in much the same way. But there are incompatibilities between Windows 8 the 1.x version Sysinternal's Desktops utility, I have to imagine that something more complex is going on.
However, in Spy++, each Windows 8 style application appears as standard Window with the WS_EX_TOPMOST style set, which would make sense, assuming they are nothing special. With respect to the Start Menu, it appears as a window of class ImmersiveLauncher created by explorer.exe. Perhaps explorer has developed an aversion to having multiple instances...
Using the old version of SysInternal's Desktops, the explorer instances in the additional desktops work fine, but do not load pinned items nor load the desktop background and icons.
Is there any documentation on why Windows 8 behaves differently from past versions when multiple copies of explorer.exe are running in different desktops?
(This is purely for curiosity's sake)
(Yes, I know there is a Desktops 2.0 version available which supports Windows 8, but it uses interesting workarounds, like switching to the original desktop when the windows key is pressed. It also seems to trigger some initialization within explorer.exe when the desktop is loaded for the first time beyond simply starting the process.)
I am developing an educational software solution where I need to clone the screen of one computer on 5 or 6 LCD screens. The screens would be 15-20 feet apart.
Is there any hardware or software that can help me do this? Each screen will just replicate the screen of the computer. I basically need to split and duplicate the video & audio signal.
I need the solution for Windows or Linux (any one) on the computer. The cloned display screens have no software - they are just LCD TVs.

If you have seen a Dell XPS in actions you probably have noticed its nice media buttons above the normal keyboard:
alt text http://blog.evolvedsoftwarestudios.com/wp-content/uploads/2008/03/img-1397.jpg
They are flashing when the notebook is starting and when you touch them.
Does anybody know how to make these buttons flash programmatically?
I had an old IBM laptop that had a keyboard light LED mounted in the top of the LCD frame (where the iSight is on a MacBook or MacBook Pro). I found that I could access this light via /proc/acpi under Linux.
I wrote a simple script that flashed the light on and off by interacting with /proc. There's a posting on my blog with the code.
You might want to try running an Ubuntu live CD and seeing if it detects the buttons, and if you can access them via /proc. A quick search showed that the newer XPS systems work out of the box with Ubuntu, so it'd be a good starting point.
