I would like to add graphing to my User Controls in ASP.NET MVC. I am hoping for some ideas or a guide on how to approach this issue. I have searched around and found no helpful answers to resolve this issue. I was thinking of doing crystal reports but they don't boat over well in ASP.NET from my previous experience. I would just like to know some ways to go about tackling this problem. So again what I'm trying to do is add graphing to MVC User Controls from a ViewDataDictionary that's passed to my User Control.
You could go with google charts for free, or something like Dundas (which is EXCELLENT) if you are willing to pay.
I hope I've understood your question.
I have been happy using the JFreeChart.net graphing system. It is a port / semi-port of javas famous JFreechart. It has alot of capabilities, and the output looks very good.
It took me 30 minutes to do my first graph, but that was mostly because you have to pay for the documentation (not the code), so i was working off the samples, which I later found to be very adequate.
Screenshots and examples are shown here

Flex Charting, ChartDirector and Yahoo's Charts are decent. Chart Director has a good support net, and the guy is very responsive to questions and feature requests.
You could also check out .dot net charting. We've been using it for a few years at my job and it's worked fairly good for us. We build reports internally through various systems and it has served us well so far.

I recently watched great google talks speech about Cling - C++ language interpreter. But I wonder if anyone except people at CERN (where it is developed) are using Cling, and how good it is from non-collider-physics-scientist point of view, can you write desktop apps with it?
There are some videos of uses cases different from the High Energy Physics: http://www.youtube.com/results?search_query=cling+c%2B%2B (I think first couple are the relevant ones)
It has the potential to be very useful, but it is very young. There is no documentation that I could find, no dedicated mailing list, no online tutorials. I was able to get small toy code to run, but couldn't figure out how to use it productively on a large library yet.
Cling project is well established one. You can find more information in their official website cling. They also have a forum
Thanks
Does it happen that no one ever needs histogram in Delphi ?
Google gave me a bunch of half-baked code snippets. But it means that each time you need one - you have to invent one more ad hoc bycicle.
Torry mostly told me about some very expensive closed source Math Statistics or Financial packages, that as a subproduct have histograms. But they are very expensive and since you have no source code, each time you install update onto IDE/RTL/VCL you're probably screwed, until the vendor would make (soon ? ever?) updated packages. Given thatvendor is still does exists.
S.O. told me nothing, nil.
For what i found...
Mitov.com provides some histograms in PlotLab. which told to be free for non-commercial. Alas, it is again closed-source, and if the Histogram - quite fancy let's admit -is the onlything i need from it - why pay the whole price ?
One more example http://DSpatial.sf.net
Just few years ago i used it in Delphi 5, but even then i felt the author is loosing interest in the project. I made few enhancement, fixed some bugs, he merged them and that's all. The component was not very useful and lacked upon features, yet better than nothing. Now the project seems to be completely dead. Good old days, etc. But i do not want them back :-)
And Stack Overflow seemingly carries no single question about it. But maybe just no one bothered to create topic, after search found nothing ? I mean, Delphi was created for database access, histograms are one of basic ways to visualize data, and no one crosses them ? Something with nice style, with rich mouse tooltip like in HTML/CSS/JS on http://www.moskva.fm/stations/FM_95.2 ?
Or is this too domain-related and not ever possible to have good abstraction ?
TChart is a control that ships with most versions of Delphi. TChart can be used to make histograms (bar charts) in style. The following give you some ideas about how to use it: http://www.digitalcoding.com/tutorials/delphi/Simple-steps-to-create-Delphi-chart.html and http://delphi.about.com/od/adptips2006/qt/chart_selectbar.htm .
If you need something with code, google the pages at delphiforfun.org/programs/oscilloscope.htm . These are not controls. The oscilloscope article has a histogram with source. Some of the other projects at the site have other histogram graphs with source..not elegant but useful and free. Use them as a template to make your own control.
The link at http://delphiforfun.org/programs/Math_Topics/probability_distributions.htm shows how to make your own statistics displays with "histograms." This example makes use of TChart.
Here is some more stuff to try I found looking at my resource file:
http://wiki.lazarus.freepascal.org/TAChart, http://members.home.nl/mvanwesten/en_lazarus.html , http://www.martinole.org/TAChart.html ...some of these are GPU components that supposedly work with some versions of Delphi. Perhaps this is your lucky day as there is some source code. The first and third listed probably will work reasonably for histograms. You may have to write your own statistics algorithms.
Found this thread while doing some searching. The ImageEn component suite has a THistogramBox component. It's the NOT prettiest thing in the world, but it's the only one I've found so far.

I came across a histogram example in a gdiplus package available for download from code central. I don't know if it will do what you need but when I saw it I remembered your SO question.
HTH.
If you were using firemonkey, you could just created a series of TRectangles in series. They can be made unclickable by turning hittest off. Or is that too easy and straightforward?
I'm looking to revamp our mobile site with something simple for phones below the ambiguous smart phone category and something a little more interesting for the phones above this category. I'm not interested in WAP/WML for this project. I'm building a ASP.Net 4 MCV 2 app and using MBDF
What I'd like to know is how best to define this differentiation when using MBDF? Screen size, Javascript, SpportsTouchScreen etc. are all in MBDF along with others but I'm not sure where to draw the line and where the data is most accurate for the broad number of devices.
What do those of you out there developing for this spread of hardware & software split on?
Thanks,
Denis
P.S. I've done my research on xHTML MP1.0 - 1.2 and the best practises for implementation to ensure broad coverage but I don't want to restrict the newer phones out there to what the base line can see.
I personally use simple mobile browser dedection script and limit max screen width to 240px. I also use simple AJAX and JavaScript calls too.
Above setup works fine for 90% of my visitors but my sites aren't business critical sites.
You can try http://wurfl.sourceforge.net/ but .net api is not as good as PHP one
So after a bit of testing myself I think I'm going to stick with testing if they support JavaScript and Touch using the MBDF. This line in the sand isn't perfect but it seems like the best out there to me.
Here is a neat little tutorial on Browser Detection using JavaScript
Browser Detection
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:
nzFotolog
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.

What do you use to capture webpages, diagram/pictures and code snippets for later reference?
Evernote http://www.evernote.com and delicious http://www.delicious.com

I just have an emacs instance running on my home machine, under screen. Whereever I am (and have network) I can connect to it remotely. I stick all useful urls, birthday present ideas, future dates, code snippets, ideas for docs etcetc in there.
I rarely have doodles/diagrams I need to capture, I tend to draw them in ascii in my file if needed.
I must admit I'm a bit stuck if I have no network/wifi somewhere, but that's rarely the case.
I find google notebook is very good for drive by code snippeting and google bookmarks especially as when used with the google toolbar, for web pages.
The benefit of these tools are that they are available from any pc on the web, though a good use of semantic organisation using labels is recommended.
Here's my response to a similar question:
The combination of OneNote with a tablet PC is awesome! I was a bit of a skeptic at first. I used the trial version and then forgot about it. A year later I had an unruly collection of files, project related emails, notebooks and scraps of paper all scattered throughout my life. I went back to OneNote and all my problems went away. Some highlights:
Everything is searchable. The character recognition is good enough that my chicken-scratch meeting notes can be searched. Text within images is searchable.
OneNote syncs with Outlook so finding meeting notes is a breeze.
I now embed all files into OneNote - pdfs, spreadsheets, word docs, images, web clippings.
OneNote is constantly saving all changes so, combined with a scheduled automated backup, everything is in one place and is safe.
There are some built-in collaboration tools I have yet to try but that look useful.
It is SO worth the price. It allows you to get started on a project and avoid all that time spent deciding how to organize things.
Zotero, is a nice plugin for Firefox.
SnagIt
captures everything you could want, and lets you annotate it.
I prefer to use the good old url for delicious
Apart from that i use the Scrapbook extension in firefox when i want to save something on the disk. It's possible to tag the page, edit it and remove those stupids ads before saving it.
I also have a Wiki on a stick that i carry around on a usbkey for code snippets that should go to other clients when i'm travelling around
Mostly, my code snippets are embedded into projects i carry on the same usb key, which allows me to demonstrate some technologies right off to the client and get his advice based on a demonstration, not a listing of code...
For screen shots, I use a mix between ScrapBook and ScreenGrab. They are both firefox plugins that are pretty amazing when you need to get a screenshot of a page for editing. Works great for consulting.

It's a little primitive, but I've been using tiddlywiki (self-contained, single-file wiki) http://www.tiddlywiki.com/ which works good for basic text and markup. I combine it with a plugin to sync it with Outlook's notes (http://syncoutlooknotes.tiddlyspot.com/#SyncOutlookNotes) so that I can then sync it to my blackberry using the standard outlook-blackberry sync mechanism. This has the significant advantage that I can look at my notes and even write new notes when I'm out and about, away from my laptop, or just don't feel like lugging the laptop around to a meeting that I don't really need it for.
I'd prefer using something more advanced like Onenote, but being able to take my notes with my in the little blackberry has turned out to be a significant advantage.
Google Notebook is very convenient tool. You can clip and save any parts of web pages without leaving your browser tab. The Notebook plug-in automatically saves them as separate notes in your notebooks and keep the links back to the original web pages. You can organize your clippings later by moving them between your notebooks and/or tagging them. Very good for code snippets and references.
