I want to make a charting control for an embedded device using Silverlight for Windows Embedded. Currently i am planning to use line shape for drawing the graph.
My question is if its a good approach(performance wise) or should i look for other options.
Or if any controls are available for SWE.
Thanks
Silverlight is not a proper answer to drawing charts on an Windows Embedded Compact device. You should go for using (or creating) a native GDI element. If performance is very important (e.g. for a fast-updating chart), you might also consider DirectDraw.
The best way in a commercial project would probably be to use a readymade component, such as this one.
You can find somebody else's experiences and advice here for pointers to what to look for when doing this yourself. If you expand your post with more details about what you are actually trying to achieve, I might give you a more detailed response.
The answer is stop using Silverlight, since Microsoft is abandoning the product. Do it in Flash—or better yet, use HTML5 and JavaScript.
In recent windows embedded applications that use windows universal apps I would highly recommend oxyplot.

These plots are the best I've found on the internet so far and very easy to use. Best of all they are free. You can get these using a NuGet Package manager which makes getting updates fairly simple.

I need to be able to use the modern CSS3 and javascript support of Chrome in a powerbuilder classic 12 project.
I found this post Memory leak with Chromium Embedded interop ActiveX control using CEFSharp WPF
where it seems that a member has successfully created an interop activex control. This is what I need to do and I need some help doing so.
If you want to USE the interop ActiveX control like mentioned in the post you included than simply use it the same way the other person did. Find out where they got the interop control and use it like normal in PB.
I think that you are wanting to develop an ActiveX wrapper which will then be used in PB. As the name implies (wrapper) just create an ActiveX project in Visual Studio and start mapping the properties/events/functions until your wrapper is complete. If you didn't know the basic steps for creating a wrapper than it shouldn't take more than ten minutes on the internet to get an idea of what that is and how to do it.
Also to help you out being a new StackOverflow member, I'd suggest using better tags for the best results. I see why you chose a few of them but 3 of 4 have fewer than 100 followers so your question is not being seen much at all (thank goodness for you on this one). I'd have put this under .NET, C# for top exposure and maybe keep the chromium tag which will help people searching for the answer down the road, it isn't helping you find the answer with less than 100 followers.
Oh, if you need someone to write the wrapper- I am looking for work and can do it for few hours/days pay depending on how much you need exposed.
i wanted to develop a DICOM Image editor in Asp.net
are there any library available for that.
or can i do something like
create an Jpeg from DICOM editor. edit the same image with lines or shapes and convert it back to DICOM Image file is that possible? if yes how?
i am new to DICOM. hence please help me to understand the DICOM.
There are a number of DICOM libraries for .NET. Refer to this question for more info.
UPDATED: another one
As far as an ASP.NET viewer - what do you want this viewer to do. In other words, what is the target audience? Is it mobile users? Then silverlight, wcf and flash are out - the most used web-based larger-screen mobile device is the iPad, which supports none of those technologies. Is it desktop users? Flash could be the answer then, the install-base is quite high, and Flash has good support for a variety of image formats.
Do you need this viewer to be diagnostic-grade? In other words, do you need 16 bit window/level? cine loop for ultrasounds at the correct frequency? If yes, then you'll need to figure out some of this yourself. Existing mobile tools aren't so great at some of the above (specifically 16 bit grayscale).
HTML5 has some of the above capabilities, and is mobile-friendly. Anyway, start with the intended use for this tool, and that will lead you into a specific direction based on the requirements you come up with!
Here's a good place to get started:
Medical Image Format FAQ - DICOM Information Sources
An open-source library that could be suitable for ASP.NET development is mdcm that allows you to develop Silverlight assemblies that could be used from your web application.
There is also a successor to mdcm denoted fo-dicom, however I am not sure whether fo-dicom currently is applicable to Silverlight.
There are about four implementations I can think of that are capable of loading SVG graphics into a Delphi application.
One of those, by Mattias Andersson, who is the author of FMX.Canvas.VPR
, works with FireMonkey, but he's not yet prepared to release the code.
A second one, by Martin Walter, works with the VCL, but developer has quit Delphi and has no plans to convert to FireMonkey.
A third one, part of the AGGPAS framework, works with the VCL, but no FireMonkey.
A fourth one is in development by Jason Southwell, but no date has been fixed yet.
So my question: what road to take if I want an SVG component today, without trying to reinvent the wheel a fifth (and probably more) time?
I'm Mattias Andersson -- the author of FMX.Canvas.VPR; I can say that I'm still actively working on the SVG solution. I guess once I have properly added support for gradients and text rendering then I can release a first beta version. I'm relying on TXMLDocument and that is a bit restrictive in what you are permitted to do (IMO), so I've had to invent some workarounds (maybe a better option would have been to implement my own XML class from scratch.) Also, I've had to do some run-time patching of the FireMonkey classes in order to make everything work correctly. The good part is that I'm actually implementing things according to the SVG interface specifications.
The SVG component I've been working on has been released as part of our Apesuite for Firemonkey.

Getting involved with Mattias Andersson in the development is the best option:
FMX.Canvas.VPR by Mattias Andersson looks promising and VPR is proven to be an excellent project
No spoon-fed SVG FireMonkey component working out-of-the-box is available as of the time of posting (extensive web search made in general).
You could also consider using Chromiumembedded. Just load the svg in the embedded browser. You can then mix Delphi code with javascript, mix in html and css, etc.
This way, you can just leave it up to Chrome how to draw stuff fast (for example whether to employ gpu acceleration or not).
You'll get proper svg support, it's easy to integrate into your application, it's flexible, and there is lots of documentation and example code available online.
I need to create a photo gallery for a website running IIS 4.0 or IIS 5.0 (im not sure which). It needs to display a low resolution version of the gallery to anyone, and it must show both the low and high resolution images for "priviledged" users. So I need access priviledges, photo albums and once the site is complete, the person I am doing this for needs to be able to upload their own images to the gallery. It also needs to have a minimal interface as it needs to be integrated into an existing website.
So I need some advice on this with the direction I should approach it.
Does anyone know if their is a customisable gallery out there that can do something like this, such as Coppermine or Jgallery or something. The alternative is to use a web framework like Ruby on Rails, CodeIgniter or Sproutcore (each which require learning a new language). The framework would be more work, but the existing galleries may not be customisable enough. The important bit is the user privileges in an admin panel.
I am relatively new to "web programming", although not new to normal/games programming. I have a few years experience with C/C++ OpenGL and Java. I have also read up on MVC etc, and did hello world with sproutcore, so I kinda get the idea. Although learning a framework is a much heavier investment.
What are your thoughts?
If you don't want to re-invent the wheel you could use Gallery2 (requirements here). It runs on IIS -- you'd just need PHP and a database. It's very configurable (including user accounts), has lots of plugins, and its open source if that's not enough. Also, the development and support communities are large and active.
you could always go the route of Dotnetnuke and then use Ventrian's Simple Gallery module (http://www.ventrian.com/Products/Modules/SimpleGallery/Demo.aspx)
Using DNN offers a ton of functionality, including the security you need, and it would save you from doing any web development.
If you are a bit more adventurous, try Smaltalk based Aida/Web and specially Aida/Scribo CMS (currently still in beta), which include Gallery so called scriblet as well. Scribo scriblets are otherwise web components which you can include directly into a text. You therefore add a gallery directly into a surronding text. See for instance a presentation as a Gallery for example.
I would recommend my own but... If it weren't for the low/high resolution thing with permissions I think it would fit the rest of your needs. I'm going to leave a link just in case you want to take a look at it:

It's also open-source (although the license is not the best) and you can change it at will if you want. The code itself is clean and self-explanatory. The downside is that I haven't developed it for some time now :(
Having faced a similar dilemma myself I have to say that I found Gallery2 and Coppermine both far too all-encompassing and difficult to customise to the degree I would have wished. I ended up rolling my own using straight, procedural PHP with various bits of jQuery for the GUI fancy bits. At the same time I was able to bake in some e-commerce and data gathering for my wedding photography clients, ending up with something which exactly matched my needs. Certainly, the gallery aspects of this project were, for a complete programming (although not HTML) neophyte, the least challenging - it's exactly the sort of thing PHP is made for.
I'm now taking my first faltering steps with CodeIgniter for my next project (photoblogging software) and I can already see that the framework would make a gallery project very quick, simple and secure.
Flickr.com and their API may be suitable from what you described.

I'm currently working on upgrading a product for the Chinese market. The target is a ARMTDMI7 with a QVGA display. Most resources I've located on the net are targeted at desktop or web programming rather than embedded devices.
Can anyone suggest some tools and
resources that might be useful?
What are the best techniques for
extracting literal strings and
communicating with translators?
I suggest looking at EasyGUI but that depends on what graphics controller you use.
EasyGUI is a tool that simplifies design of user interfaces and comes with complete source code and driver for a varity of display controllers.
For localization you can use EasyTranslate that gives the translater a graphical representation of the interface. This lets the translator see how the translated texts fit on the screen.
EasyGUI is available with unicode support aswell as right to left script.
Freetype might be good for rendering fonts.

There are many ARM microcontroller forums which will help you find what you're looking for.
Atmel has a line of ARM7 processors, and they are pretty friendly to those who make a hobby out of this, so there's a lot of information on this processor. It won't be the same, but generally the tools and libraries can be used across the ARM line so you might find some help here - you'll want to focus on the AT91SAM7 series.
If you have more specific questions, you will probably get some reasonable response here.

It sounds like you need to upgrade an existing codebase to make it support multiple languages.
If so, the fact that this is on a microcontroller shouldn't be an issue - I'd drop that fromt he title and focus on the language you're using (c?) and ask how to convert your program for internationalisation.
This is a problem many people have solved on a variety of platforms, and the fact this you're on a microcontroller doesn't mean that the same tools and such don't apply - the relevant factor is the language you're using
