  • ASP.NET MVC Response file should not download

    - by Shawn Mclean
    I am generating a .cxml file on the server and pushing it to the browser based on certain queries. If I just link to a .cxml, it does what I expected and opens it in the respective application. How can I generate a file and push it to the browser just like if it was linked to a file without it asking me to download it? The link looks something like: http://localhost/MyController/GetFile?q=TheQueryStringParam Thanks.

  • The server method xxx failed (asp.net ajax)

    - by vikasde
    I have a website project, that is working fine. However every once a while certain ajax pages (that make calls to a webservice) throw a "the server method xxx failed". I have ELMAH installed, however do not see any stacktrace or anything. The worst is that I can not reproduce the error locally. I just get an email notification from ELMAH. Does anybody know how I can fix this issue?

  • ASP.NET Dashboard / Widgets

    - by davemackey
    I'd like to build a dashboard interface for an application I am working on. I want users to logon and get a birds eye view of the status of applications, outstanding issues, etc. I'm wondering if there are some good, pre-made controls rather than writing these from the ground up?

  • non contiguous String object C#.net

    - by Kazoom
    By what i understand String and StringBuilder objects both allocate contiguous memory underneath. My program runs for days buffering several output in a String object. This sometimes cause outofmemoryexception which i think is because of non availability of contiguous memory. my string size can go upto 100MBs and i m concatenating new string frequently this causes new string object being allocated. i can reduce new string object creation by using Stringbuilder but that would not solve my problem entirely Is there an alternative to a contiguous string object?

  • Variable scope and the 'using' statement in .NET

    - by pete the pagan-gerbil
    If a variable is at class level (ie, private MyDataAccessClass _dataAccess;, can it be used as part of a using statement within the methods of that class to dispose of it correctly? Is it wise to use this method, or is it better to always declare a new variable with a using statement (ie, using (MyDataAccessClass dataAccess = new MyDataAccessClass()) instead of using (_dataAccess = new MyDataAccessClass()))?

  • Call .NET Webservice with Android

    - by Lasse P
    Hi, I know this question has been asked here before, but I don't think those answers were adequate for my needs. We have a SOAP webservice that is used for an iPhone application, but it is possible that we need an Android specific version or a proxy of the service, so we have the option to go with either SOAP or JSON. I have a few concerns about both methods: SOAP solution: Is it possible to generate java source code from a WSDL file, if so, will it include some kind of proxy class to invoke the webservice and will it work in the Android environment at all? Google has not provided any SOAP library in Android, so i need to use 3rd party, any suggestion? What about the performance/overhead with parsing and transmitting SOAP xml over the wire versus the JSON solution? JSON solution: There is a few classes in the Android sdk that will let me parse JSON, but does it support generic parsing, like if I want the result to be parsed as a complex type? Or would I need to implement that myself? I have read about 2 libraries before here on Stackoverflow, GSON an Jackson. What is the difference performance and usability (from a developers perspective) wise? Do you guys have any experince with either of those libraries? So i guess the big question is, what method to go with? I hope you can help me out. Thanks in advance :-)

  • ASP.NET/IIS: Tell IIS do not check for file existence

    - by AgileMeansDoAsLittleAsPossible
    In my Global.asax.cs, I have: routes.MapRoute("AssetCss", "css/{*path}", new { controller = "Asset", action = "Index" }); I also have this in a view: <link href="/css/Root/index.css" rel="stylesheet" type="text/css" /> The problem is that the AssetController does not invoke Index when /css/Root/index.css is requested. This is because a file actually exists at the path /css/Root/index.css. If I recall correctly, there's a checkbox setting in IIS that basically says "Do not check that a file actually exists at the request path [instead, let the RouteTable handle it]." (At least there is in IIS 6.) Is there something I can put in my Web.config that sets this IIS setting to true? How do I tell IIS to let my MVC routes handle the path even if a file exists at the path?

  • Where is the windows app installed + .NET + VS2005

    - by The King
    I deployed a windows application in the following website http://StagingServer/MyProgs/MPP/ on my intranet site, using the Publish Wizard of VS 2005... I accepted all defaults (including Offline support). My users were also able to install the same from the path specified. But when I try to find out the exact location of the EXE in the client, it is not pointing anywhere. I also tried a file search but in vain. Initially I thought the application is running from the server itself, but we were able to start the app, even when the server is down (ofcourse it takes more time to search for updates initially). Ps : The app is showing even in control panel... Raja

  • .NET, ASHX, "Server cannot append header after HTTP headers have been sent" after sending PDF Streem

    - by Inturbidus
    I visit my ASHX file, and it outputs a PDF perfectly. If I visit the very same ASHX with a different query string (I append DateTime.Now.Ticks to the end each visit), and I get this error: Server cannot append hader after HTTP headers have been sent. My code is below: copy.CloseStream = false; document.Close(); var r = context.Response; r.ExpiresAbsolute = DateTime.Now; r.BufferOutput = true; r.ContentType = "application/pdf"; r.AppendHeader("Content-Type", r.ContentType); r.AppendHeader("Content-disposition", "inline; filename=" + context.Server.UrlEncode(formType.File_Name)); r.BinaryWrite(copyStream.ToArray()); r.StatusCode = 200; r.End(); originalReader.Close(); copy.CloseStream = true; copy.Close(); There is no other place in this code that headers are sent. You are seeing the entire interaction with the Response object. I've tried to use r.Flush(); and r.End(); I've also tried not sending them if they are already there, but this causes other issues.

  • Making a button click and process using javascript with Asp.Net

    - by user944919
    I'm having two buttons and one button is hidden. Now when I click the visible button I need to do two things 1.Open Iframe. 2.Automatically make the 2nd Button(Hidden)to be clicked. When the second button is clicked I need to display the message on top of the IFrame which I have mentioned as function showStickySuccessToast() Now I am able to open IFrame but I'm unable to make the Hidden button clicked automatically. This is what I'm having: <script type="text/javascript"> $(document).ready(function(){ $("#<%=Button1.ClientID%>").click(function(event){ $('#<%=TextBox1.ClientID%>').change(function () { $('#various3').attr('href', $(this).val()); }); }); function showStickySuccessToast() { $().toastmessage('showToast', { text: 'Finished Processing!', sticky: false, position: 'middle-center', type: 'success', closeText: '', close: function () { } }); } }) </script> Here are my two buttons how I'm working with: <a id="various3" href="#"><asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="Button2_Click"/></a> <asp:Button ID="Button2" runat="server" Text="Button" Visible="False" OnClick="Button2_Click"/> And in the button2_Click event: Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, GetType(Page), "Script", "showStickySuccessToast();", True) End Sub

  • Querystring formatting in asp.net MVC 2

    - by Stuart
    Seems like a straitforward question but I can't quite figure it out myself... I have an actionlink like so Html.ActionLink( "Test", "test", new { q = "search+twitter" } ) This produces a url string as follows http://myserver/test?q=search%2Btwitter But i would like to preserve the plus sign (which i assume is being UrlPathEncoded) so that I get the following url http://myserver/test?q=search+twitter Is there an easy way to do this whilst still using Html.ActionLink ?

  • Unique visitor counting in ASP.NET MVC

    - by Max
    I'd like to do visitor tracking similar to how stackoverflow does it.. By reading through numerous posts, I've figured out some details already: Count only 1 IP hit per 15 minutes (if anonymous) Count only 1 unique user-Login (per day?) Now that leaves the question of the real implementation.. Should I log the two factors live into a table (and increase count) | IP | timestamp | pageurl | Or do the counting AFTERWARDS (e.g. using IIS log files - which don't include the user, right? I know there're some similar posts outside, but NONE really has a great solution in my opinion yet..

  • Losing context from JQuery post with ASP.Net MVC

    - by Dan
    I have a JQuery dialog box on a page that calls something like this: $.post("/MyController/MyAction", { myKey: key} //... And this successfully gets here: [HttpPost] public ActionResult MyAction(int myKey) { //do some stuff return RedirectToAction("AnotherAction"); } The problem is that the RedirectToAction has no effect on the webbrowser. I am guessing this is because the JQuery post is kinda on a different 'tread' so it doesn't know where to send the response? How do I get the browser to load the new response?

  • .NET Web Service Proxy is adding special characters in XML

    - by xkingpin
    My web service proxy seems to be adding special characters like "*" and "#" etc. within the xml nodes. My proxy created lists using arrays of objects. I am trying to create a generic list and then doing list.ToArray() to set the proxy MyProxyObject[] object. Is this the cause of the problem I am having? I plan on running fiddler on the request later but it is over SSL and I do not have access to the URL at the moment. Here is an example of the XML that is generated: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> * <soap:Body> o I'm a little concerned because the special characters are even occuring before the array nodes
