I am about to start making a simple little video editing application, and I was trying to decide what system to create the GUI in. I know a lot about the Windows API, and actually, all of my programs thus far have been written in it. I would really like to use the new WPF framework though; however, I am a bit concerned about the fact that C# may not be ideal for a performance-oriented application. And I'm not positive, but I don't think it is possible to use SIMD instructions in C#?? Of course, my video editing program will use DirectX, and then I've read about problems of using that in C#. So then I had the idea that maybe I'd write the "core" of the program in C++ and somehow link it to its GUI through DLLs or something. Of course, that could be really messy... Any ideas? Thanks!
Why not managed C++ and either winforms or c#/WPF ui?
I wouldn't use MFC.
WPF has a future, and skills learned in it are saleable. Not so sure about MFC...
I wouldn't worry about performance of C# versus C++; there have been several benchmarks that show an approx. 10% speed increase using C++. The major issue is object creation/deletion. Reducing this is one of the main issues with C# performance.

I work for a small Point of Sale Company, and we are working on a in-house tool to make our lives easier when it comes to ticketing and troubleshooting. Part of my task in this tool is to write a 'softphone' in C# WPF that we can use to accept incoming and make ongoing calls with.
We currently use OnSIP as our SIP provider, and are looking to build custom software to essentially allow us to auto-generate support tickets based on the phone number of the incoming call. In addition we will need call transferring, recording, hold/wait, etc.
The question that seems to be causing me the most trouble is really where to begin on something like this. Thoughts?
I'm presuming this is a desktop application?
Lookup pjsip.org, it's a portable C library which is very well proven. It will allow you to do all that you are asking, although it'll take you some time to write the wrapper code - you can find examples on the internet, however we have written a wrapper ourselves which I'll check on as we had intended open sourcing it. This is because when we did this last year, the examples just didn't work too well :-)

Let's say that someone decides to create a game without a game engine or library of any sort.
C# (or any popular language) is used
They have 2D sprites and 3D models with animations
They aren't sure of what IDE to use
Based on this information how would they get images displayed onto the screen?
I imagine that a console window would be out of the picture. (Pun intended)
Yes, a console window would be out of the question :)
You need to access the built-in Graphics API. On Windows computers, this is DirectX. On other operating systems, it is typically OpenGL.
Both APIs are very cumbersome, and are completely different. Without a library you typically have to be in C/C++ to use them.
As far as IDEs it depends on what you are developing for. Visual Studio is fine for windows, others you need to find something that compiles for it (probably using gcc). Anything will work, its just standard native code.
Good luck!

I have done some development in C# and I love the language and the environment. I am taking a Perl class, and yes it sounds like easy learning curve, but there are some questions which I think need to be asked essentially as a server-side developer.
So far, if I want to create a stripped-down program which runs on a Windows machine then I can create a console application. C# + .NET are good enough that I can achieve most of the functionality.
Now, when scripting languages come into picture, I agree that they are easy to use and easy to write. The languages have super-rich functional libraries. But is is just a choice that we make to use a scripting language as opposed to a fully-fledged framework like .NET? Or are there some things that only scripting languages can do, and would be very difficult to achieve from languages like C# and Java?
C# is Turing-complete, so the answer to your question is "no".
.NET has nothing to do with your question; other languages have their own "full fledged framework"s (or more than one).

I want to write simple application with some 3D objects for Windows OS.
The application is very simple, like a gallery where we can move and see some pictures. When users go to the some picture and click on it a window will open and show picture with some information.
Which is the best framework for this task WPF, XNA, or something else? Application will be written in C#.
I can not say which is best, but I have done a while ago some things with the WPF 3D API and I liked it.
It was IMO very simple to use and the rendering seemed to be relatively fast. A really nice thing I found, was that it has an object-model that contains high-level-events such as mouse-down and click. Therefore you don't have to do much math. However, maybe provide also other APIs such high-level services, I don't know.
I would not try to create an action-game with it, but for a small app as you have described, I think it is worth a try.
Unity has been used for similar stuff. It can work on browsers (via a plug-in) or as a program, has a lot of documentation and most of the work involved in creating a 3D environment and interface is already done. Code can be written in Mono (open source C# implementation), JavaScript or a Boo, a modified Python scripting language.
It works in Windows, MacOS, iPhone, iPad and Android. And it is free in the standard version, or really cheap.
XNA is a little lower level, so it will require more work to get things started. It supports Windows, WP7 and Xbox 360.

Here's the situation:
I need to develop a desktop tool that will take in an input from Oracle (text) and it's output is a print of a layout generated by that tool.
The tool needs to be fast and able to print easily and not much extra software required on client PC's which ALL run Windows.
Now i've studied Java, PHP in the past however I don't want to use PHP for the Desktop App
and I have my doubts about Java in regards to Printing and developing the GUI.
It seems to me like with C# I can develop the GUI easier and faster, and most PC's have a lot of the tools required for the GUI in the OS (.net framework).
A tool like NetBeans helps, but more often than not the GUI design is either broken
or shoots across the screen when I make a simple change.
So now I'm thinking about starting in Visual C#, however I would like to get your
opinion.
And from my past VERY short .NET programming experience, I can still remember that deploying over the internet is easy as well, with JAVA I've had some issues with that as well before I got it to work.
So in short:
Windows environment
Lot of GUI design
Fast app that runs on client Windows PC's without much 'extra' software installing
Easy print programming
THANK YOU!
My preference would be C# or VB.NET with Windows Forms. WPF is also worth looking at, and will give you the most modern UI, but it has debatably a steeper learning curve attached.
