I need to rotate an image clockwise only just once after a certain operation. I felt so lazy to include rotating logic to my current image operations class then I come with this idea. What I need is already built within windows explorer, so is it possible to trigger windows explorer's rotate operations within a c# application for a valid file specified?
I have doubts that I can't access to that kind of functionality but I wanted to ask to make sure.
Thanks!
You're better off not relying on the feature since it is not part of the API and can disappear at any time. You should just do your own image rotation.
I don't think its possible to do it with Windows Explorer's integrated photo rotating, but you should check out the awesome image editing/processing library called ImageMagick. The original API is a native windows (dll) API, but there is a good .NET wrapper that is easy to use.
Here it is:

There are also wrappers for two dozen or so other languages, linked at ImageMagick's site:

I need to implement some sort of library that allows me to pick (one or multiple), edit, crop, resize, move and apply other effects on user's photos that will be sent to a server later.
I tried to write my own code to do so but it takes much more time and it's quite difficult.
Do you know some libs (open-source or not) that give me the chance to do so?
For editing I know:
Media plugin https://github.com/jamesmontemagno/MediaPlugin
UCrop: https://github.com/NAXAM/ucrop-android-binding
You can bind any library from native to xamarin
Just use SkiaSharp, its free has tons of documentation and is cross-platfrom
I've been running around the web for a while now looking for a solution to this problem, but I'm quite disheartened by now to find something that will fit all of my requirements. So here goes.
I'm trying to build a desktop application that uses the Kinect for Windows sensor to control a visualization of digital library (as in, the place you go to for books) assets. I'm quite versed in using the official MS Kinect SDK and already have a neat utility framework for prototyping at hand, so I'd obviously love to make use of it. This plus the desktop app theme of things says the whole shebang will need to be in C#, which is fine by me.
On the other hand, the visualization part already exists and looks gorgeous, but it's JavaScript (and specifically, JIT i.e. javascript infovis toolkit). It has all the bells and whistles I need and it's neatly animated. Also, I'm a noob at JavaScript.
The point is, how do I avoid rewriting either one into the other's language while still allowing them to talk at runtime?
So, do you know any way to either
A) embed a JIT visualization (e.g. radial tree visualization) in a windows application in a way that allows me to manipulate the graph at runtime from a C# class (e.g. selecting a new node to be animated into focus) or
B) send C# events to JS to react to gesture input at runtime? Is this something ASP.NET can do?
I have a feeling the result will be a weird mix of desktop and web technology, but any pointers to the right sort of technology is greatly appreciated.
Maybe you should look at this projects about using Kinect with JavaScript:

My C# application uses DirectShow and requires DirectX to run. I would like check that DirectX is enabled at start-up, can anyone advise the correct method to do so?
Thanks
DirectShow is not a part of DirectX. There is only some intersection in video renderer using DirectDraw and Direct3D, and wrappers over audio APIs which are in fact no longer independent but wrappers over other APIs. I would say there is nothing to check for and DirectShow is already an OS core component, but if you have some specific concerns then what are they? Maybe you could attempt to create some DirectX object directly on app startup and see if this attempt is successful.
I think I'm right in saying if the DirectX DLLs aren't installed on the host machine, your application wont even start. Beyond that, you should always be checking that creation of DirectX objects succeeds before attempting to use them.
I am not able to apply 3D effects on WPF's built-in WebBrowser, because it is just a thin wrapper around the native ActiveX-Webbrowser, which isn't based on WPF. I saw most of the places people suggested about one Link ,but I m not able to make it work in my application and it is having so many dlls which I don't want. Can anybody suggest me any other good alternative solution present then?
Maybe you forget to copy the needed awesomium.dll & AwesomiumProcess.exe with your executing assembly (which are not .Net assemblies).
I also have some difficulties to run with awesomium but it's not impossible.
I can recommand you the Troymium/TroymiumNet which is actively maintain by its developers.
I use it on Microsoft Surface to connect people to their facebook account.
I've never used it, but you could try Berkelium with berkelium-sharp.
Using ExternalInterface in AS3 is it possible to call OS (C#?) functions within XP?
Example: Set the desktop background to a image supplied by a flash app?
If it is possible would it be different calls when applied to different OS. And what about cross over the Mac?
Any information would be great
Thanks
If you're launching the swf from within a C# app, external interface will do just fine. Nothing will change on the flash side, but you'll need to go through a couple hoops to get it to work in C#. It's not as simple as AMF or External Interface to JS.
All the communications to C# get converted to XML describing the data, and you've gotta write XML to send back to flash. Other than that though, its relativly simple.
Here's some info on how to do it. The AS portion is Flash 8/AS2, but the C# portion should say the same.
When working with Flash from a webpage or as a desktop app, you are limited to a small security sandbox and you will not be able to make any relevant OS call. I thought that switching to AIR would give the developper more flexibility but it doesn't seem correct either. From "The Pros and Cons of Adobe Air":
AIR apps have
file access, clipboard access, support
multiple windows, support drag and
drop, and can trigger notifications
(toast in Windows). If you app needs
to interact with the desktop in other
ways, the chances are that AIR is not
suitable. For example, there is no
access to COM automation, and no way
to execute external applications. The
reason is to maintain cross-platform
compatibility. That's a worthy goal,
but it would be good to have a way out
of the sandbox. Unlike Java or .NET,
you cannot extend AIR with custom
native code libraries. Nor can you
call operating system APIs.
As Alex Jillard commented, if your swf is called inside a C# desktop application, you should be able to access more OS funcionalities although I'm not sure how.
You could use as already mentioned AIR. Another idea would be to use HippoHX (I haven't written this, the similarity with my username is just coincidence). It runs on top of the NekoVM and gives you unrestricted (so no limitations like in AIR ) access to the system.
