  • Drawing rectangles on a grid in a web browser

    - by Dhruv
    I would like to create an online, simple WYSIWYG drawing editor allowing people to draw rectangular shapes. I'm thinking of a grid which the lines and points can snap on to, ensuring that the lines are strictly vertical or horizontal. I will be parsing the rectangular shapes to obtain some area calculations and compute certain things. How can I achieve the drawing ability? The new canvas tag is good but people have been telling me that IE does not support it. I found some Java applets but I have never programmed in Java before. Is there a way to do this using pure javascript or jquery? Does ASP.NET help at all? Thanks.

  • How can I configure Windows Server 2008/IIS 7 to send email via an asp.net web application?

    - by Steve French
    I recently moved a long-functioning web app from a Windows 2003 server to a windows 2008 server. Everything works fine, save for the email service (send password and the like). The code works on my local machine and the original web server. The system throws no errors, but the message stays endlessly in the Queue. I have granted full access to all relevant users (Network Service, IISUsers, etc). Is there something I'm missing, or does IIS7 just not send email via web applications?

  • Web Service returning object with null fields

    - by Xaiter
    Never seen this one before. WebService.Implementation imp = new WebService.Implementation(); WebService.ImplementationRequest req = new WebService.ImplementationRequest(); return imp.GetValue(req); The object that imp returns is not null. It's returning an ImplementationResponse, as expected. But all of the fields in that object are null. Which is not expected. The WebService, currently, just returns some constant dummy data. We've tested this on another developer's machine, works just fine. I suppose I should also note that the WebService should throw an exception if I pass null into the GetValue method. It doesn't. Not for me. Any idea what could be wrong with my environment that could make a WebService return an object, but make every value in that object null? And somehow 'magically' return this mystery object when it should be throwing an exception?

  • Web script to click some buttons and save some html pages

    - by Serge
    I am trying to go through a site with a bunch of links. I click on a link, save the page, click on a button, save a page. Then go back and repeat it for a huge number of links. I want to write a script to do that for me. I know C++ but I want to do Javascript for this, what is a good place to get me started? What would be a good IDE to use?

  • "Easiest" way to track unique visitors to a page, in real time?

    - by Cooper
    I need to record in "real time" (perhaps no more than 5 minute delay?) how many unique visitors a given page on my website has had in a given time period. I seek an "easy" way to do this. Preferably the results would be available via a database query. Two things I've tried that failed (so far): Google Analytics: Does the tracking/reporting, but not in real time - results are delayed by hours. Mint Analytics ( http://www.haveamint.com/ ): Tracks in real time, but seems to aggregate data in a way that prevents reporting of unique visitors to a single page over an arbitrary time frame. So, does anyone know how to make Mint Analytics do what I want, or can anyone recommend an analytics package or programmed approach that will do what I need?

  • CSS content overflowing containing div

    - by kaese
    Hi, Currently have a problem with some DIVs overlapping their containing DIVs. See image below (the 3 products at the bottom): All the body content of the page is held within the #content DIV: div#content { width: 960px; float: left; background-image: url("../img/contentBg.png"); background-repeat: repeat; margin-top: 10px; line-height: 1.8em; border-top: 8px solid #5E88A2; padding: 10px 15px 10px 15px; } And here is the CSS for the product boxes within the #content div: .upper { text-transform: uppercase; } .center { text-align: center; } div#products { float: left; width: 100%; margin-bottom: 25px; } div.productContainer { float: left; width: 265px; font-size: 1em; margin-left: 50px; height: 200px; padding-top: 25px; text-align: right; } div.product { float: left; width: 200px; } div.product p { } div.product a { display: block; } div.product img { float: left; } div.product img:hover { opacity: 0.8; filter: alpha(opacity = 80); } div.transparent { opacity: 0.8; filter: alpha(opacity = 80); } And here is the HTML for the boxes: <div class="productContainer"> <div class="product"> <h2 class="upper center">A2 Print</h2> <a href='../edit/?productId=5&amp;align=v' class='upper'> <img src="../../wflow/tmp/133703b808c91b8ec7e7c7cdf19320b7A2-Print.png" alt="Representation of image printed at A2 Print through MyPersonalPoster." /></a> <p class="upper">16.5 inches x 23.4 inches<br /><strong>&pound;15.99</strong></p> <p class="upper smaller"><em><span><span class="yes">Yes</span> - your picture quality is high enough for this size</span> </em></p> <p><a href='../edit/?productId=5&amp;align=v' class='upper'><span>Select</span></a></p> </div> </div> <div class="productContainer"> <div class="product transparent"> <h2 class="upper center">A1 Print</h2> <a href='../edit/?productId=11&amp;align=v' class='upper'> <img src="../../wflow/tmp/133703b808c91b8ec7e7c7cdf19320b7A1-Print.png" alt="Representation of image printed at A1 Print through MyPersonalPoster." /></a> <p class="upper">23.4 inches x 33.1 inches<br /><strong>&pound;19.99</strong></p> <p class="upper smaller"><em><span><span class="no">Warning</span> - your picture quality may not be sufficient for this size</span> </em></p> <p><a href='../edit/?productId=11&amp;align=v' class='upper'><span>Select</span></a></p> </div> </div> <div class="productContainer"> <div class="product transparent"> <h2 class="upper center">Poster Print (60cm x 80cm)</h2> <a href='../edit/?productId=12&amp;align=v' class='upper'> <img src="../../wflow/tmp/133703b808c91b8ec7e7c7cdf19320b7Poster-Print-(60cm-x-80cm).png" alt="Representation of image printed at Poster Print (60cm x 80cm) through MyPersonalPoster." /></a> <p class="upper">23.6 inches x 31.5 inches<br /><strong>&pound;13.95</strong></p> <p class="upper smaller"><em><span><span class="no">Warning</span> - your picture quality may not be sufficient for this size</span> </em></p> <p><a href='../edit/?productId=12&amp;align=v' class='upper'><span>Select</span></a></p> </div> </div> Any idea what could be causing these DIVs to overlap? What I'd like is for all the boxes to fit within the #container div as expected. It's driving me crazy! Cheers

  • Serialize ASP.NET Web Service HTTP POST request results

    - by nigative
    I am trying to serialize my webmethod output (rename XML element with results), So far [return: System.Xml.Serialization.SoapElementAttribute("results")] before method declaration works fine with soap requests, but I am looking for something that would work the same way with HTTP POST/GET requests as well (right now I get return class name as element name)

  • Are there any Spreadsheet apps that are as easy and powerful to use as Vim?

    - by ovatsug25
    I'd like to use a spreadsheet that lets me move around cells like I do in Vim. As well, the more commands that are attributed to keyboard shortcuts, the better. Particularly stuff like making Text-to-Columns which is one of my more frequently used features in Excel. I don't mind learning the shortcuts if they allow me to just look at the spreadsheet page and forget about everything else. edit: The way I am thinking about the Spreadsheet right now is as if every cell is its own unique file. There should be a command where I choose to open that file and edit it right on the spot within the view of the spreadsheet. So I guess I want different modes like in vim which have commands and there should be one mode that is hooked up just to do operations or formatting which would be similar to command mode in Vim.

  • WCF interoperability with WSDL proxy and performance consideration advise.

    - by user194917
    I'm essentially writing a broker service. The requirement is that I write an API that acts as an intermediary broker between our in-house developed services and a 3rd party provided API. The intention being that my API abstract the actual communication with the 3rd party API from our internal systems. The architect on the project chose WCF as the communication framework. The problem is that 70 percent of our subscriber applications are written in .Net 2 and as such have no access to the class libraries required to implement a WCF proxy. The end result being that our proxy classes are loosely based on the code auto generated by the WSDL tool as opposed to the SvcUtil tool. My question is, although I have no issues implementing the required proxy classes using basicHttp as the actual binding and using the WSDL tool, are there any special considerations that I need to take into account in this scenario? I.E proxy optimizations and the like. Thanks in advance.

  • aptana/eclipse blocks other apps

    - by waquner
    Hi, I've got a fresh win7 installation, the only apps installed so far are aptana (beta 3)/eclipse and firefox + chrome (except antivirus and drivers) Every time I start aptana, chrome and firefox are blocked, so firefox can't load a webpage (or sometimes takes veeeery long) and chrome doesn't even take care of events (so for example hovering over a link doesn't change the cursor and a click does...nothing or typing in an url, press enter - nothing happens) First I thought, aptana downloads something and blocks my internet connection... but IE works well and also there are no signs in the taskmanager (cpu%, network or memory) When I close Aptana, all works as before. I tried updating Java, which didn't help... On my office-computer I use the same apps and it works perfect. Got any ideas? TIA, waquner

  • Deserialising Json to derived types in Asp.Net Web API

    - by IoChaos
    I'm calling a method of my WebAPI sending a json that I would like to match (or bind) with a model. In the controller I have a method like: public Result Post([ModelBinder(typeof(CustomModelBinder))]MyClass model); 'MyClass', wich is given as a parameter is an abstract class. I would like that at, depending of the type of json passed, the correct inherited class is instantiated. To achieve it, I'm trying to implement a custom binder. The problem is that (I don't know if it's very basic but I can't find anything) I don't know how to retrieve the raw Json (or better, some kind of serialization) that comes in the request. I see: actionContext.Request.Content But all methods are exposed as async. I don't know who this fits with passing the generate model to the controller method... Thanks a lot!

  • Reading XML or objects from a Web service

    - by Shawn
    This is my first time working with webservices and I am a bit lost. I successfully called the functions, but I only can get one value from the service. I read that the easiest way is to read xml or create objects and then call their values. Currently I use functions that return the desired value but I need to call them 3 times to get all the data witch is a waste of time and resources. I tried to call the service with the URL and use it as a website or getting the service to work the same way without importing into the program. The thing is that i cant find a way to pass the values into the url, because of that i get only blank pages. What is the fastest way to get my data from the services? I need city name, temperature and a flag if the city is valid. I need to pass the zip code to the service. Thank you. My current code wetther.Weather wether = new wetther.Weather(); string farenhait = wether.GetCityWeatherByZIP(zip).Temperature; string city = wether.GetCityWeatherByZIP(zip).City; bool correct = wether.GetCityWeatherByZIP(zip).Success; I tried it that way // Retrieve XML document XmlTextReader reader = new XmlTextReader("http://xml.weather.yahoo.com/forecastrss?p=94704"); // Skip non-significant whitespace reader.WhitespaceHandling = WhitespaceHandling.Significant; // Read nodes one at a time while (reader.Read()) { // Print out info on node Console.WriteLine("{0}: {1}", reader.NodeType.ToString(), reader.Name); } This one works for the yahoo page but not for mine. I need to use this webservice - http://wsf.cdyne.com/WeatherWS/Weather.asmx

  • Best tool for monitoring Coldfusion interoperability with .Net web service

    - by John Galt
    Is there a tool to see the message sent to webservice hosted on an IIS server? I have a webservice written in .Net and our ColdFusion people are having trouble building a "complex" parameter. This problem is described from a ColdFusion perspective at: adobe forum question It runs when called from a .net client. While hosted on a server inside our LAN, I put it out on a public server so the WSDL could be viewed: please take a quick look at this WSDL here When the CF developer runs her code, she gets: java.lang.IllegalArgumentException: argument type mismatch ...and I am wondering if there is a tool I could run on the server that hosts my webservice to see if it is even entering the WS or is being rejected by Java code that CF uses and is not really even getting to my webservice.

  • How can you setup multiple WSGI apps on one server?

    - by Shakakai
    I'm working on a python based server product where a user can install WSGI-based python apps on their server. I can enforce any restriction on the application structure or format to make this easy. The user workflow would be: browse an app market, showing a list of WSGIpython apps select an app and choose "install" the app would be downloaded from a remote server to the user's server the http server would then have to be configured to start serving that application from the app's id, ex. a blog app with an id of "blog" at "/blog/", so all requests below /blog/ would be seen as root by the blog application. Any suggestions on how to set something like this up? Holler if my flow of consciousness lost you ;)

  • Web developement learning env

    - by David Oneill
    I am currently learning Ruby on Rails. I currently do all my development on my laptop. However, I know in all "real world" situations, I will be connecting to a dedicated server that will hold the site. So here is my question: what are the pros and cons of developing on the machine I use vs running the website on a separate server?

  • Office 2007 Mail Merge: How do I view field names instead of data?

    - by One Monkey
    I've just received a document which forms the basis of a mail merge as an attachment and I need to view the field names like they display in 2003 with the double chevrons e.g. <<titles>><<initials>><<surname>> However even though I get a dialogue as I open the docx file saying that it is going to attempt to merge from a file (which I don't have) and I cancel that operation the document still displays merge data e.g. Mr A Test Instead of the field names. I have clicked on the fields which turn grey to demonstrate that they are fields but I can't find a way to make it display the field names not the data. I don't even know where it's getting the data from as I don't have the data source file for the document to use.

  • The underlying connection was closed when using a WSDL web service

    - by joshlrogers
    I am trying to consume this WSDL service: Transit Time Service I successfully connect and get a response the first time but on subsequent calls I receive the exception: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. I overrode the GetWebRequest in the reference.cs file as such: protected override System.Net.WebRequest GetWebRequest(Uri uri) { HttpWebRequest webRequest = (HttpWebRequest)base.GetWebRequest(uri); webRequest.KeepAlive = false; return webRequest; } This hasn't yielded any improvement. I am at a loss as to what options I have now, does anyone have any other ideas that I could try so that I may avoid this error? Thanks in advance! Josh
