I want to create a HTML5 Application on a Windows 8 Computer which provides product information for a user in the store. Does anyone know if it is possible to set up the windows 8 in a such away, that the user cannot exit the HTML5 App?
This isn't possible on Windows 8; the soon to be released Windows 8.1 has a "Kiosk Mode", which seems to be what you are looking for. From Windows 8.1 kiosk mode locks systems to a single app:
Generally speaking, kiosk mode is something that’s intended for use in corporate and shared computing settings — like public information terminals. It would, for example, make an excellent way to lock a point-of-sale terminal in to the “cash register” app and prevent would-be procrastinators from tabbing out and surfing the web.

Is it possible to tap a windows phone to a NFC reader connected to a windows laptop running a windows store app?
what I want to achieve is to send a message from windows phone to windows store app, and trigger a registration action.
any advice will be greatly appreciated.
Yes, it's fully supported through the Windows.Networking.Proximity APIs. However, the problem you may hit is that it's difficult to find desktop/laptops that support NFC proximity. You can easily find NFC readers that can read smart cards and tags, but most of these don't support proximity.
The only USB dongle I've seen that supports proximity is this Sony one, however I've also heard that there are reliability problems with it: http://www.sony.net/Products/felica/business/products/RC-S380.html
I have been programming for windows since about v2.1 and am interested in some apps for the phone now that it seems to be coming of age.
Search as I might, I cannot find a developer's unlocked version of a phone other than CDMA one and I can't use that as there is only AT&T and TMo available out here in the boonies.
Buying a dev's version for Android was simple as going to Moto's site and dropping one in the shopping cart.
If msoft are wondering why there are so few win-phone devs and/or, they might start looking at how hard or easy it is to get started. I have installed the SDK and the emulator is OK, but not something I would trust enough without testing it on my own phone.
Any helpful thoughts and suggestion on where to get a phone that it is not against the warranty to unlock?
You can use any windows phone as long as it supports the OS version (windows phone 8/8.1 is not supported in the older models) you're coding for. You don't need a developer version of a phone.
You need a developer's account though (should be 20/year now) and take a look at this page for registering your device. For older devices you need Zune software but it's not needed for windows phone 8 and up.
And if you want to use a real device for testing, without wanting to buy a device, you could use the Remote Device Access service
With it you can use a real device (located in Tampere/Finland) over the internet with your browser. Limitations include the lack of physically touching/rotating the device, and that calls/SMS are disabled both incoming & outgoing ones.
Per the Windows 8.1 documentation, the UIElement.Holding event, the "exact timing of what the system interprets as a holding action is adjustable by users through system settings"
What exactly is meant by this? It would suggest that the user should be able to change the timing of what is interpreted as a holding action through the device's settings, but I see no such option on Windows Phone 8.1.
Or is this an option available to the developer? If so, how can the developer modify this setting for the app?
Thanks
As per the comment here on the Microsoft Phone Dev Center forums from Rob Caplan (a Microsoft employee),
"This is not adjustable by apps. It is a user setting. I believe that
on Windows systems it will be based on the double click rate (most UI
timings are based on that). I'm not sure on the phone. There may be an
adjustment in the ease of access centre."
There is no such adjustment on Windows Phone 8.1 Developer Preview in the Ease of Access settings.
It seems like there is nothing I can do here. Perhaps it is possible to code your own gestures in Silverlight?
I know this is a very basic question but I really want to know if regularly testing your app on windows phone 8 developer unlocked device adversely affects the device performance and working or in some manner can affect device?
I've done this on 3 separate phones and I've never noticed any difference!
If your apps are all well behaved and you don't reach the limit of 10 such apps installed on your phone then the answer is no. If you do have 10 such well behaved apps installed then you will not be able to test more apps until you uninstall one of the previous apps.
If your apps are badly behaved with memory leaks, battery hogging etc. then of course they will adversely affect your phone until you uninstall them.
If you develop very large apps which use large amounts of storage then you may run out of storage on your phone until you uninstall them.
If you are trying to develop some kind of phone app virus and you succeed then again installing (which will happen automatically if you test on the device) will install the virus on your phone. Hopefully such an app would fail MS certification.
I Have windows phone 8 And I want to Develop apps and Deploy it Freely.is this possible.
Ya, max 10 developer app or unsigned apps are allowed to install in your phone.
I assume what you want to do is sideload the apps . For that you need to developer unlock you lumia620 first , which obviously is going to cost you.Please check price for developer unlocking you phone with microsoft.
Other than that it is impossible to load apps freely ,if it is not through App store.
Hope my answer helped you.
It is possible to load any number of unsigned xap files onto a Windows Phone device provided it is fully unlocked (interop unlock). How you go about getting your device to that state presents a challenge. So far, only the Samsung ATIV S has been unlocked to that level for Windows Phone 8.
Once you have fully unlocked your phone you effectively have free reign over your device being able to fully access components such as the registry or file system.
Both Samsung and LG have provided back door diagnostic tools on their phones that facilitate making the needed registry changes to completely unlock their phones. Whether such features are available on other brands has yet to be discovered.
If you are a software developer, you will probably want to get your hands on an ATIV S before they disappear.
