I am developing a LOB web app using jquery mobile for Windows tablets. I was going to use the feature that was available on Windows 8 which is to take a picture on the file picker. and send the image in a form. However, since I updated yesterday my computer to win 8.1 there is no Camera App in the file picker anymore. I don't know if there is a way to have it back there. Or if there is another photo app that implements the filepicker contract.
Thanks

We have developed an app using Xamarin Forms which targets iOS, Android and Windows Phone. We are using camera feature to take/select photos to be uploaded to the app and the feature works well on all three mentioned platforms.
We have some users facing issues on few windows devices. When a user tries to download the app from Windows App Store, they receive following error:
"This app is not available for your phone because it requires front facing camera”
I have attached screen shot showing the error for reference. The screen shot is taken from Nokia Lumia 635. Our finding that this device has only back camera, no front camera and we believe this might be the reason for above mentioned issue.
Ideally, users should not get this error as this device has back camera and they still can get the photos.
Is this a known issue in windows phone world?
Can this be fixed from code, device permissions?
Is this a device specific problem?
Any ideas?
I have an application written in VB.NET that I want to move to Win10. It will always be a desktop application, however I would like it to have a start icon / tile in Win 10. Looking around I found this exact question which suggests to create a Metro App (now I believe called Windows App) which launches the desktop app. This is also discussed in this thread. So the questions;
These threads are a little old is the best way in Win10 to give a desktop app a Windows App Tile by using a Windows App as the Launcher for the desktop app?
It appears that in Win10 Microsoft has now allowed non-store apps to be installed in Update Security > SideloadApps. This needs to be enabled to install the App, but does this need to be always enabled. For example what happens after install if the user turns it off, will the app then not start?
For example I see in this link that there are 2 Registry keys to change, basically AllowAllTrustedApps and AllowDevelopmentWithoutDevLicense. Is it possible for my desktop installer to change these keys, install the Windows App (and everything else) and then change the keys back again?
Uninstalling? If I created a Windows App which only launched my desktop app then there is a possibility that the user uninstalls or deletes the Windows App, meaning my desktop app would be orphaned and lost. Any suggestion on solving this?
According to your description, I think what you need is Desktop Bridge. There is no need to use a Windows App as the Launcher for the desktop app.
You can try with Desktop App Converter, with this you can bring your existing desktop apps written for .NET 4.6.1 or Win32 to the Universal Windows Platform (UWP).
And after converting, you can replace the Assets generated by Desktop App Converter (DAC) automatically to provide custom Tiles/Icons. For more, you can refer to Manually convert your app to UWP using the Desktop Bridge.
Is it possible to upload an image created by the phone using Sencha Touch but without any dependency on PhoneGap? Basically my app will be accessible via the web, and not installed natively on the device. I want to be able to select an image from the phone storage and then be able to upload it to the service. I effectively want the same functionality as you would get with the file upload control on a normal desktop browser.
Is this possible, and if so how?
There is a current solution in its infancy, but it works. I tested it on my Nexus 7 using Chrome. Here is the list of compatibility:
Android (4.0 up) browser support as regular
Google Chrome for desktop and mobile
iOS Safari browser support from version 6.0 (not tested on mobile)

Desktop webbrowser and mobile browser are different in lot many cases. To access file upload option you need to access the OS API which is not possible using javascript only. Phonegap provides us option to connect js with device API. If you can find a way to do this, without using Phonegap, then may be you can fix, or else its not possible.
Is it possible to create an app that "only" shows while using Share charm? I do not want the fullscreen app to be opened via live tile as there is no content to be displayed. I want it to be displayed only through Share charm.
No, it is not possible for an app to be shown only as a Share target. All Windows Store apps have a tile on the Start Screen that can be used to launch the app.
We have created a C# windows form application that uses an ActiveX control to display video stream. Now we are planning to develop the same application in windows phone.
Is it possible to use ActiveX controls (OCX Files) in windows phone development?
No its not. You can only use Silverlight and XNA on Windows Phone.
You already have a Media content available using Silverlight that you can use to stream Video. You can find more information here:

It can get as simple as something like this:
