  • which technology is best for a Facebook application Ruby on Rails or C# and ASP?

    - by Johnny
    hi, My friend and I want to write a Facebook application. We've narrowed down the list of possible technologies to Ruby on Rails and C# with ASP. Here are the pros and cons we've thought of. Cons: ASP - proprietary tools like Visual Studio etc. cost (lots of) money. We both don't know ASP (although we're not bad at C#). RoR - It's scripting so might be harder to maintain. My friend doesn't know RoR at all (but he's a fairly proficient programmer so will probably be able to pick it up quickly). Pros: ASP - Facebook has an official SDK for .NET. RoR - I know RoR. It's open source, free and has fast development time. What says the community? Is there something we haven't thought of?

  • How to Automatically Refresh Data on Page Using Ajax on an Interval?

    - by Karnak
    I would like to load an XML file every 30 seconds and display its contents inside an HTML page. So far I know how to load the file, but I don't know how to automatically refresh it and display its updated contents. It would also be great if it did some error checking and if it displayed error.png image when it's not able to load data.xml file. Here is my code: <head> <script> window.XMLHttpRequest { xmlhttp = new XMLHttpRequest(); } xmlhttp.open("GET", "data.xml", false); xmlhttp.send(); loadXMLDoc = xmlhttp.responseXML; f = loadXMLDoc.getElementsByTagName("foo") function buildBar(i) { qux = (f[i].getElementsByTagName("qux")[0].childNodes[0].nodeValue); document.getElementById("displayBar").innerHTML = qux; } </script> </head> <body> <script> document.write("<ul>"); for (var i = 0; i < f.length; i++) { document.write("<li onclick='buildBar(" + i + ")'>"); document.write(f[i].getElementsByTagName("bar")[0].childNodes[0].nodeValue); document.write("</li>"); } document.write("</ul>"); </script> <div id="displayBar"> </div> </body> After searching the internet for a few hours I found many examples on how to do this, but I didn't know how to implement it in my particular case. I am not a programmer, so please be kind. I would really appriciate any help. It would mean a lot.

  • Where to find .NET version usage statistics?

    - by Mash
    There are some technologies like LINQ and WPF which are nice, but installation of .NET 3.5 is still slow procedure. It's important to understand - among Windows users how many of them have .NET 3.5 installed? Is there any good up to date stats gathered about .NET Version availability/usage? I've searched a lot, but can't find. Update: .NET version IS present in web-agent strings for FF and IE at least. So there SHOULD be somebody who have that information. Anyone with access to really large web-site logs? Update 2: I also understand Vista means that user have 3.5, but XP is still dominating the market.

  • ASP.NET GridView throwing error: "Update is disabled for this control".

    - by NTDLS
    I have the absolutely most simple setup imaginable. A single table defined in an Entity model in ASP.net v4, the model is bound directly to a GridView with AutoGenerateEditButton enabled. However, each time I hit edit, then save, the page throws the error “Update is disabled for this control" for which I cannot find a solution. What is causing this error? What can do to resolve it? <% <asp:GridView ID="MenuItemsGrid" runat="server" DataSourceID="gridDataSource" AutoGenerateEditButton="true" AutoGenerateColumns="true"> </asp:GridView> <asp:EntityDataSource ID="gridDataSource" runat="server" ConnectionString="name=dataEntitiesModel" DefaultContainerName="dataEntities" EntitySetName="MenuItems" /> %>

  • Updating .net 4.0 machine.config seems to have no effect

    - by Jon P
    I'm feeling stupid. I've just created my first ASP.net 4.0 site after working my way though over the years from 1.1 upwards. We have several settings at the machine.config level that I need to migrate to the new 4.0 machine.config. I though I had be adding the required connection strings to the connection string section of the following two files: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\machine.config C:\Windows\Microsoft.NET\Framework\v4.0.30319\machine.config When I created a new website in IIS and assigned it to the ASP.net 4.0 Application pool I only get the default LocalSqlServer connection string. I tried editing the name of this in the two files above to indicate which file it was in, but there was no change. Are there machine.config files in other locations I should be looking at?

  • Why can't I open a new window on my jquery ajax callback?

    - by KyleGobel
    to show my problem in a couple examples... THIS WORKS $.post("SomePage.aspx", { name : "value" }, function (data) { alert(data); }, "text"); THIS DOESN'T WORK $.post("SomePage.aspx", { name : "value" }, function (data) { window.open("http://www.google.com"); }, "text"); In the first example, I get alerted with what i'm expecting. In the second example, nothing happens. No window is opened. If I add an alert or something before or after the window.open call, the alert works fine, but the window doesn't open. If I add a window.open completly after the $.post method, the window opens fine (of course this doens't help me at all). I'm wondering why I can't open a window in the callback. What do I have to do to be able to open a window? I'd like to open a window to show some fancy results. Any help is appreciated, thanks.

  • How do I call C++/CLI (.NET) DLLs from standard, unmanaged non-.NET applications?

    - by tronjohnson
    In the unmanaged world, I was able to write a __declspec(dllexport) or, alternatively, use a .DEF file to expose a function to be able to call a DLL. (Because of name mangling in C++ for the __stdcall, I put aliases into the .DEF file so certain applications could re-use certain exported DLL functions.) Now, I am interested in being able to expose a single entry-point function from a .NET assembly, in unmanaged-fashion, but have it enter into .NET-style functions within the DLL. Is this possible, in a simple and straight-forward fashion? What I have is a third-party program that I have extended through DLLs (plugins) that implement some complex mathematics. However, the third-party program has no means for me to visualize the calculations. I want to somehow take these pre-written math functions, compile them into a separate DLL (but using C++/CLI in .NET), but then add hooks to the functions so I can render what's going on under the hood in a .NET user control. I'm not sure how to blend the .NET stuff with the unmanaged stuff, or what to Google to accomplish this task. Specific suggestions with regard to the managed/unmanaged bridge, or alternative methods to accomplish the rendering in the manner I have described would be helpful. Thank you.

  • Best way to get a date in .NET?

    - by frenchie
    I'm getting a string back from my page and I want to make sure it's a date. This is what I have so far (it works) and I just want to know if this is the "best" way to do it. I'm using .NET 4. int TheMonth =0; int TheDay = 0; int TheYear = 0; DateTime NewDate; var TheIncomingParam = Request.Params.Get("__EVENTARGUMENT").ToString(); char[] TheBreak = { '/' }; string[] TheOutput = TheIncomingParam.Split(TheBreak); try { TheMonth = Convert.ToInt32(TheOutput[0]); } catch { } try { TheDay = Convert.ToInt32(TheOutput[1]); } catch { } try { TheYear = Convert.ToInt32(TheOutput[2]); } catch { } if (TheMonth!=0 && TheDay!=0 && TheYear!=0) { try { NewDate = new DateTime(TheYear, TheMonth, TheDay); } catch { var NoDate = true; } }

  • How do you make the script wait for the status of an Ajax get request before continuing?

    - by codeninja
    Basically what I'm doing is checking for the existence of an object, if it's not found, the script will try to load the source file using getScript. I only want to check this once though then return true or false to the function that calls fetch() fetch:function(obj){ ... isReady = false; $.getScript(obj.srcFile,function(){ isReady=true; warn("was able to load object "+key); }); return isReady; } but return kicks in before the script loads =/ later the script is loaded but the function returned false. This is the beauty of asynchronous I suppose... What's the best way to handle this... Maybe I could check again at some other point if the object exists? Or maybe there's a better way to do this where I dont have to potentially lock the browser?

  • What are supported clients for an asp.net webpage?

    - by Maestro1024
    What are supported clients for an asp.net web page? I am trying to document an asp.net website and I am unsure what I should say as far as client support. Are there limitations for asp.net as far as browsers? I have used IE and Firefox does it not work with some of the other browsers (chrome or safari)? Should I say the client is limited to any specific OS (I would expect it to work with a Mac or a Linux box)?

  • Trying to call JS Code that is passed back from AJAX call....

    - by Dutchie432
    Okay, so I have an javascript function that retrieves some HTML... function updateQuestions(i){ var url = 'getQuestions.php?sys=' + i; if (receiveReq.readyState == 4 || receiveReq.readyState == 0) { receiveReq.open("GET", url, true); receiveReq.onreadystatechange = handleQuestionsUpdate; receiveReq.send(null); } } function handleQuestionsUpdate() { if (receiveReq.readyState == 4) { var a=receiveReq.responseText; document.getElementById('questions').innerHTML=a; checkSpeakers(); //Error Occurs Here, even though checkSpeakers() is a function in the returned HTML chunk. } } This HTML is not just HTML, but it is more specifically a form and a chunk of javascript. The javascript is hard-coded into the HTML and not referenced by <script src=".."> Is it normal that this retrieved JS code isn't recognized upon call-time? If so, what is my alternative if I need the JS to change every time the div is update? Now

Can anyone spot the error? Data passed for the else clause is specifically "". Thank You.

  • Ajax request. Which callback is executed first complete or success?

    - by Gutzofter
    I could spike this to find out, but I'm going to use SO. In my unit tests (qunit) I use the asynchShould (alias for asynchTest) test. Part of the assertion is to wait for the completion/success of the request. Like this: asyncShould('talk to customer list server', 1, function() { stop(2000); var forCustomerList = newCustomerListRequest(); forCustomerList.page = 'helpers/helper.php'; forCustomerList.data += '&action=customerListServer&DB=11001'; var originalSuccess = forCustomerList.success; forCustomerList.success = function(msg) { if (msg.flash !== undefined && msg.data !== undefined && msg.status !== undefined) { ok(true, 'json structure correct') } else { ok(false, 'json structure not correct'); } originalSuccess(msg); start(); }; testController.getServerData(forCustomerList); })

  • Using AJAX in Rails: How do I change a button as soon as it's clicked?

    - by sdc
    Hey! I'm teaching myself Ruby, and have been stuck on this for a couple days: I'm currently using MooTools-1.3-compat and Rails 3. I'd like to replace one button (called "Follow") with another (called "Unfollow") as soon as someone clicks on it. I'm using :remote = true and have a file ending in .js.erb that's being called...I just need help figuring out what goes in this .js file The "Follow" button is in a div with id="follow_form", but there are many buttons on the page, and they all have an id = "follow_form"...i.e. $("follow_form").set(...) replaces the first element and that's not correct. I need help replacing the button that made the call. I looked at this tutorial, but the line below doesn't work for me. Could it be because I'm using MooTools instead of Prototype? $("follow_form").update("<%= escape_javascript(render('users/unfollow')) %") ps. This is what I have so far, and this works: in app/views/shared: <%= form_for current_user.subscriptions.build(:event => @event), :remote => true do |f| %> <div><%= f.hidden_field :event %></div> <div class="actions"><%= f.submit "Follow" %></div> <% end %> in app/views/events/create.js.erb alert("follow!"); //Temporary...this is what I'm trying to replace *in app/controllers/subscriptions_controller.rb* def create @subscription = current_user.subscriptions.build(params[:subscription]) @subscription.save respond_to do |format| format.html { redirect_to(..) } format.js {render :layout} end Any help would be greatly, greatly appreciated!

    Is there an advantage to learning Java or .NET first? (ie. would the transition from J2EE to .NET be significantly easier than the reverse?) Do you think that one platform has overtaken the other in terms of industry use? (feel free to be as biased or as objective as you like) see also: Java or .NET?
