How to use the Media Viewer in a WP8 app - c#

I'm trying to add a media viewer page on my app (very similar to the photo app on WP), so my first idea was to open a new Pivot Page with one photo on each page, but it overload the memory when there is to much photos and I don't have the zoom in / zoom out fonctionnality.
Then I found this cool example provided by Microsoft who do exactly what I wanna do :

The problem is, I've tried many things, but I can't get it to work. Do you have any idea how I could use this cool Media Viewer ? What classes should I import? How to implement it in my project?

The Media Viewer class is indeed not that simple!
I've also started to tweak it so it would fit my purpose, the solution isn't finished, but you can already take a look at it here: https://github.com/Depechie/ImageSliderMediaClass
I changed the class so that it would act as one horizontal image scrolling overview, without the zooming capability.

How to take a photo without preview. Android. Xamarin. C#

I have a sample code from xamarin.com:
How to click the Button and take a photo without preview?
Maybe you have an articles, or videos. I'm new at Xamarin, so it will be awesome, if i'll get as more details as possible.
This article will get you started with a stream of the camera to a surface in your app. It shows you how to get to the Camera class, which in turn has a TakePicture method that you could use for your problem.
Please also take a look at this answer on SO on a similar question (native Android, but the same concepts apply), which suggest showing the preview on a 1x1 surface because you can't really prevent the preview on Android as far as I know.
PS: don't forget to add the correct permissions in your manifest for Camera access.

Windows Phone Custom Control Design and Implementation

I am working on a windows phone app, in which I will need to add a costom "cover-flow" kind of control like how it looks like in the Spotify app below:
Note: user can swipe from right to left to change song.
I don't think Windows Phone SDK provide any controls support this, so I was wondering how such a thing is implemented.
I think it is either faked by a pivot page with dynamically adding/deleting pivot items, or maybe it is a custom control.
If I want to implement this as a custom control, does anyone has experience about it, or any sample code/tutorial will be very helpful.
Thank you
You're looking at a Panorama control. It is available out of the box with the Windows Phone SDK.
Telerik makes a great control that does just this. It's called the SlideView control. I know it's not free, but it is only $99. Given that it might take you about 4-10 hours to create this control yourself, I'd say it's worth it. If you join the Nokia Premium Developer Program you get Telerik's controls for free.
Note: I do not work for Nokia or Telerik and this is NOT a paid advertisement :)
The swipping effect is because of Panorama page. to change music you need to handle gestures that will be a tough task . The solution is to find a hack or have some control in the background that registers the touch event and changes the music

Get Video from webcam / Ip-camera

I'm trying to implement camera security in my application. I got some SDK's from some security companys to implement there system but they all use ActiveX. My view right now is that ActiveX is kinda old?
But what is the newest way to get video from devices and display (stream) them on a screen?
What control to use in .net 4.5 WPF (and Windows 8)
I'm working on video WPF app for two years now and we had a fundamental problem with video and WPF which was never resolved, and that's variable fps-rate. This blog post goes into details.
There's also a nice library called Media Kit (by Jeremiah Morrill), it might be suitable for your problem.
In our solution we had no choice but to expose HWND's for our rendering DirectX engine. We accomplished this by using HwndHost class and extending it to our custom WPF control. Note this is the base class for windows forms host, so you get the same amount of problems as with WinForms-WPF inter op.
Also, ActiveX is the only way to display professional camera video streams in web interfaces, it's still a defacto industry standard, you'll get it from MOXA, Acti, Vivotek and various other camera equipment manufactureres.
One more thing, if you need to perform some advanced analysis of video, I'd suggest OpenCV.

Image gallery swipe UI in MonoTouch

I am looking to create a UI experience almost identical to swiping through images in the Camera Roll on the iPhone. I have 5 images that I simply want to be able to swipe through. This view will be the first view of a Tab Bar Controller that I have in place. This is my first iPhone (iOS) app attempt so if anyone feels this question needs to be broken down into smaller chunks, please let me know.
Here's an example of the paging control for MonoTouch I developed some time ago: https://github.com/escoz/monotouch-controls
Take a look at the PagedViewController. That code is actually used in my app, Quicklytics.
Use Pagecontroller.
In this example they have add label, instead of that you add your imageView.
EDIT:
For Monotouch.
The Photos module of Nimbus is exactly what you are looking for.

The MonoTouch bindings can be found here.

C# - Winforms - Animated Slideshow

Well i am developing an application whose interface requires an animated slide show
and by animated slide show i means UI components placed together change their positions after regular intervals in a sliding (animated) fashion. Let me illustrate my idea with the following image,
(source: deviantart.com)
in the image above there are three columns of UI components that i want to slide, what i could do is simply write a module to change x,y coordinates of the components that would give the animated slide effect but that does not work fine, because it is heave takes time in processing and all plus the coding will be complex and layer adjustment and all.
is there any slide show component on which instead of image i can place UI components
What are the other options i have or what is the right way to do it. Please need help.
Sounds like are looking for a carousel feature for you component. Winforms were not intended to be animated. Fortunately some companies have worked on products that support animaiton in this area but most are moving to the Silverlight and WPF platforms for those updated features. As a reader of MSDN Magazine I often come accross some interesting advertisements of Winform components that are quite interesting. Please take a look at this link. The cost of the product is quite high.
Telerik Sample Applications using Carousel feature in Win Forms
Also check out the following link to MSDN. It explains how you can reference the silverlight component as a COM object.
Using Silverlight in a Windows based application using COM
In this scenerio it could also be possible to embed a flash player with a flash animation, using one of the many (commercial and free) xml-based slideshows avaible for flash. This one for example http://www.flshow.net/.
