OpenCV in Windows Phone 7 - windows-phone-7

I want to use opencv in windows phone and not sure if any support available for that. any link / sample code would be highly appreciated

You can't. WP7 only supports managed code, OpenCV is native library.
You have 3 options:
Target WP8 instead.
Some companies (e.g. Tango, Spotify) somehow convinced Microsoft to allow native code development for WP7 platform.
Look for alternatives to OpenCV, such as AForge.NET.

Can I create an app for Google Play Store in C++?

I need to know whether I can create an app for Google Play Store in C++, or whether I have to use Java.
I don't have a JDK, so if I can use C++, then that would make things easier and cheaper.
You can look at the Qt library at http://www.qt.io/
From the Tools and Versions page for the latest version (5.5) it states:
Android NDK r10c r10c r10c
Android SDK r24.0.2 r24.0.2 r24.0.2
And in the Play Store there are a few Qt example applications:
Introduction to Qt 5
Qt 5 Everywhere
You can download an open source version of Qt from here
There are also some steps on the Getting Started with Qt for Android documents page.
PS:
I have not attempted to use Qt for Mobile (Android, Win Phone, iPhone) development but I am planning to test this sometime this year.
Edit: I see you do need the Android SDK, NDK and Java JDK but at least you don't need to code in Java if that helps.
Thank you everyone for you quick replies!
Based on your answers, it looks like it's time to give me laptop new life so I can use pure Java.
Thanks again!

DirectX sample code c++

I'm looking for source code (as I bet a lot of others are / were and will) for learning purposes of DirectX. I would like something similar to the vs2013 Graphics Editor when dealing with *.fbx files, etc. Every thing I find is old and outdated, or way to simple and does not show the basics like transformation cursor, picking objects or points on objects. I'm just looking for something basic.
many thanks in advance
The DirectX Tool Kit is a good place to start and includes some tutorial content as well. It supports loading models using the VS 2013 content pipeline that produces CMOs from FBX files.
You didn't state if you were looking to write a Windows desktop application (aka a Win32 application) or if you were looking to write for Windows Store / Windows phone. DirectX Tool Kit supports either, although the tutorial is written using a Windows desktop application template so that developers using Windows 7 could also utilize it.
You should also refer to the DirectX SDK Samples Catalog for locations of updated versions of the legacy DirectX SDK samples that build fine using VS 2013 only.

How to develop SIP (VOIP) application

I developed sip application in Android. and now I am developing it in Windows Phone 8. I am new in Windows phone and don't know anything that Which library should be use here? Do Microsoft provide free library for SIP?
Please any suggest me Which way will be best for developing or any source code or library or demo application?
I think you can start from this example.
There is a full sample app there.
Take a look at boghe, it's the SIP video client for Windows Phone 8 and Surface Pro. You'll learn a lot from there.
It also cover VoIP apps for Windows Phone 8, which teaches you to integrate VoIP into WP8 experience

Do Windows Mobile 6.5 applications work on Windows Phone 7?

And if not then what do I have to do to make them?
(Our apps are in latest C# .NET.)
No. You would need to port your apps to the WP7 platform. You may be able to reuse some code, but the UI model is completely different.
Much of the C# sharp code is most likely the same but some things like saving and loading are different as well as you having a choice between XNA and Silverlight. The link below should contain a lot of the information you need.

Is it possible to write shared libraries between iPhone, Android, Blackberry, Mac and Windows?

I'm tasked with "porting" a few apps from a Windows environment to various mobile platforms and Mac as well.
I plan on writing MVC patterned apps in which I write as many controllers as I can in some sort of universal library, probably in C or C++. Then writing the views in various choice languages (Objective C, Java, .NET, whatever) for the target OSes.
I've never attempted anything like this before, so my questions are: Is it possible to write and compile one library that can be used on iPhone, Android, Blackberry, Windows and Mac? Is it even wise to try this?
I understand that certain native methods simply won't be available on each platform.
You can create a library whose source code is portable, assuming that you properly abstract away any platform-dependent calls. You can't, however, create such a library, compile it, then use it anywhere; you'll have to compile it for each platform.
Your should take a look at the Mono Project. http://www.mono-project.com
...more specifically at :
MonoTouch: To develop iPhone applications in .NET
MonoDroid (BETA): To develop Android applications in .NET
Mono plugin for MeeGo: To develop MeeGo applications in .NET
And you know that you can develop on Windows Mobile in .NET already.
I've haven't found anything related to BlackBerry yet.
There are services like Rhomobile and Appcelerator which will allow you to do this sort of cross compiling.
I've never used either however.
