What I need is a method to display a graph of data from a tab delimited file uploaded to a website. Once the file is uploaded the program will convert the data to a graph or the graph be generated locally and sent to website, but it needs to be automated and in realtime.
Thanks,
Antone
Your question is rather broad.
The answers to these questions usually depend upon what sort of programming framework you will be using for your website. For example, PHP has some native libraries to generate graphs based on submitted data in multiple formats. But that may not be what you are looking for and using something like dojo or ExtJS might be better. Or if you are a Java/JSP person, then there are lots of frameworks that can handle this. Of course .NET might be better. I am sure the Python and Ruby folks have their own thoughts as well and then of course there is Delphi.

I have a series of pictures from some old documents which I want to digitize them and convert them to excel file or other things like this.what is the best way to do this?
Depending on the pictures you are using, you might want to consider looking into a toolkit that supports both scanning in images and OCRing them such as the LEADTOOLS Document SDK, which has TWAIN and WIA scanning features for scanning in the document images as well as OCR features can be used to convert images into document formats. As I work with the vendor of this toolkit, I can suggest a number of approaches to improve OCR recognition of the text in your images, if this is indeed something that is suitable for you.
But without knowing more details, it is difficult to give a precise answer for what you need. You should provide more information when posting a question like this. For example, describing the input pictures in more details, giving examples on what exactly they are and how do you expect to handle them, as well as elaborating on the outline of the final Excel output you are seeking.
I'm looking to create a website around a tool that plugs info from different sites into a form on mine. I'd like to eliminate/streamline data-entry. Anyone know a good way to accomplish this?
There are plenty of web scraper scripts available on github that can do data capture from web.
You will still need programming skills to change and plug those scripts as per your requirement. Here is one such parser but you must know basic DOM and programming to access information of your need from a website.
Apart from this you can also use excel sheet to access web data and then you can fill your form with that data.
You should try to learn web scraping using python. Threre are plenty of web based tutorials for it. Youtube may also be helpful.
I am planning to make a web application, using silverlight for frontend. requirement is: this frontend will be just an empty shell, and it must be language independent. it will get everything it needs to display and use from server, therefore making it language independent.
i tried to find tutorials, but there is nothing.
as far as i understand, silverlight uses xaml for all its data, so just generating it with whatever language i want shouldn't be a problem. but i don't have any silverlight experience or knowledge, so i'm not sure what is the best way to do this. for example, i don't know how will new content be generated, and what kind of structure silverlight requires.
can anyone give me some starting points?
Your requirements are rather demanding. If i can summarise:
silverlight will be the front end (or container)
you don't know what it will be showing
the content may be dynamically generated
everything, including the visual content, will be retrieved from the server
If i have misunderstood then by all means correct me or adjust your question.
Those requirements are not trivial, especially when you have no prior experience in Silverlight. Fetching data from the server is a normal behaviour in Silverlight, but fetching any generated UI content will be a slow and inefficient use of the technology platform. Silverlight is delivered via the browser, and runs on the client. If you are going to have generated UI, then you may want to consider using straight HTML instead (you can generate the contents using ASP.Net or a scripting language such as PHP). Alternatively, you can generate your required UI views from within the Silverlight app itself by either swapping in and out the appropriate pre-built piece of UI (or controls), programmatically adding new controls into the visual tree, or by loading XAML using the XamlReader class.
This answer may or may not help you much, but like i said before - put some more specific details into your question and you will get more specific answers (either add comments under your question, or post a new more specific question if you cannot edit your current one).
Edit: i have just come across this blog article from Jeff Prosise explaining the use of the INavigationContentLoader interface in Silverlight 4 to dynamically load pages from either remotely or locally. It is a detailed write-up, with a lot of code samples, it may be of use to you.
I would suggest you start at http://Silverlight.net
The "Learn" section has lots of videos that can get you started. http://www.silverlight.net/learn/
I need to put together a team to build a silverlight based application that will read an xml file and generate a Mind Map diagram based on that file.
I am new to silverlight and I need to find out what skills do I need and how difficult is it to do something like this.
I expect the typical Mind Map features available in a commercial Mind Map software, like the ability to open and collapse nodes and to move the nodes around the screen.
There is a pretty well known Silverlight implementation here: http://code.msdn.microsoft.com/SilverlightMindMap
Might get you on your way to assess what is required.
i have played around with dynamic data website. is there something similar for winforms.
if there isn't anything out there for doing the same with winforms than the question would be why not? we have a massive ERP application that we want to migrate from AS400 to .Net
Winform application. my initial thoughts were to have all the maintenances be as simple as Dynamic Data Website project.
I would think that WPF would be a better starting point then WinForms, as it has support for style to say how item of data are displayed.
Dynamic Data makes it easy to edit your DB on the web. For desktop (and web) apps take a look at the new Microsoft LightSwitch:
http://msdn.microsoft.com/en-us/lightswitch/gg441300
LightSwitch doesn't use Windows Forms. Rather it creates a Silverlight App that can run both on the desktop and the web. Pretty cool.
Dynamic data is using the routing functionality of the MVC framework. In Windows forms we don't have this approach of fetching data with URLs from a server.
I am not sure how this model could fit into Windows forms.
I think it's pretty hard to create something like dynamic data for Windows Forms.
My biggest concern is here, once you created that Framework, how do you configure it? I mean if you want to change 1 form to be a bit different than the others :-)
I think its better to generate Forms for the various tables in the Database context, using a powerful Grid control from one of the big vendors. And then you can configure those.
Remember this is a different approach then the dynamic data one, where no code is generated before compile time
I think the reason you don't see something like this in winform applications is because it's much easier to store a HTML page inside a database and then display it on the screen formatted properly when using a web application because your browser knows how to format the HTML.
You would have to, stored in the database, know where each label and field would go on the form in some sort of co-ordinates fashion (or you could use a layout 3rd party control) but the amount of work that would take might be tedious to do properly.
The dynamic data website I worked on did not take input from the user. It only displayed different web pages to the user and allowed the admin person to easily make changes to the content. If you wanted a user to beable to save data then that would even be more complex because you have to worry about validation, required fields, etc.
If you have lots of users that need to see different information based on their access level then I would just suggest having a table in the database that tells the system whether or not they should see the field on the form. Then use a 3rd party layout panel to format the visible fields.
my 2 cents
As much as Dynamic Data looks simple and cheap enough to access a database it wouldn't work for an ERP system anyways. Business systems are more than moving data between database and the user interface, they require business rule actions when saving data and while retrieving the may require some massaging to ensure meaningful presentation of storage optimized data.
If you still like to pursue this option it would be very easy to create an application that is build on top of Entity Framework.
I'm not aware of a Dynamic-Data-alike, but (having written one before, years ago, for ASP) I don't actually think it would be that hard, particularly with WPF and its templating support.
Actually if you were really clever you could probably 'borrow' the backend from Dynamic Data, and just reimplement the UI as WPF.
Would make a fun little project actually.
Alternative answer: Use Microsoft Access. No really.
Alternative answer #2: So why not just use Dynamic Data then?
