  • This property cannot be set after writing has started! on a C# WebRequest Object

    - by EBAGHAKI
    I want to reuse a WebRequest object so that cookies and session would be saved for later request to the server. Below is my code. If i use Post function twice on the second time at request.ContentLength = byteArray.Length; it will throw an exception This property cannot be set after writing has started! But as you can see dataStream.Close(); Should close the writing process! Anybody knows what's going on? static WebRequest request; public MainForm() { request = WebRequest.Create("http://localhost/admin/admin.php"); } static string Post(string url, string data) { request.Method = "POST"; byte[] byteArray = Encoding.UTF8.GetBytes(data); request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = byteArray.Length; Stream dataStream = request.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); WebResponse response = request.GetResponse(); Console.WriteLine(((HttpWebResponse)response).StatusDescription); dataStream = response.GetResponseStream(); StreamReader reader = new StreamReader(dataStream); string responseFromServer = reader.ReadToEnd(); Console.WriteLine(responseFromServer); reader.Close(); dataStream.Close(); response.Close(); request.Abort(); return responseFromServer; }

  • Pyramid.security: Is getting user info from a database with unauthenticated_userid(request) really secure?

    - by yourfriendzak
    I'm trying to make an accesible cache of user data using Pyramid doc's "Making A “User Object” Available as a Request Attribute" example. They're using this code to return a user object to set_request_property: from pyramid.security import unauthenticated_userid def get_user(request): # the below line is just an example, use your own method of # accessing a database connection here (this could even be another # request property such as request.db, implemented using this same # pattern). dbconn = request.registry.settings['dbconn'] userid = unauthenticated_userid(request) if userid is not None: # this should return None if the user doesn't exist # in the database return dbconn['users'].query({'id':userid}) I don't understand why they're using unauthenticated_userid(request) to lookup user info from the database...isn't that insecure? That means that user might not be logged in, so why are you using that ID to get there private info from the database? Shouldn't userid = authenticated_userid(request) be used instead to make sure the user is logged in? What's the advantage of using unauthenticated_userid(request)? Please help me understand what's going on here.

  • jQuery DataTables is messing op my CSS grids in IE8, how to fix?

    - by Brendan Vogt
    I am using ASP.NET MVC3 with the jQuery Datatable plug in. I am having an issues with my CSS layout when the datatable is on a page. If there is no datatable then everything displays fine. When the datatable is on the screen then it overlaps the footer of my website. I can't seem to get this to display correctly. I have a grid layout using the YUI3, and this is what I all use from YUI3 (in this order): cssreset-min cssfonts-min cssgrids-min cssbase-min This works fine in the latest version of FireFox. I am only testing on IE8, this is a requirement and most of the people at my work uses IE8. I have minified my HTML so that only the bare minimum is available. This is my HTML: <!DOCTYPE html> <html> <head> <title>My Website</title> <meta charset="utf-8" /> <meta http-equiv="X-UA-Compatible" content="IE=Edge" /> <link href="/Assets/Stylesheets/hef2.css" rel="stylesheet" /> <link href="/Assets/Stylesheets/jQuery-DataTables/css/jquery.dataTables.css" rel="stylesheet" /> </head> <body> <div id="hd">Lorem ipsum dolor sit amet, consectetuer adipiscing elit.

I have tried tried adding clear:both but it didn't work. Is the an online service like jsbin where I can paste/upload my HTML/CSS code/files? Code can viewed at: http://live.datatables.net/efosuj/3/edit. It displays correctly in the available viewer but when run separate in IE8 then it gives issues. UPDATE 2012-06-12 I managed to add the following and it works, but I would like to add it in a style, tried it but it didn't work: if (navigator.userAgent.toString().indexOf('MSIE') >= 0) { jQuery('#main-container').css('overflow', 'auto'); } This was added after the grid was loaded. Is this the only way to do this?

  • How do I use a different image for each JQuery UI Slider handle

    - by Tom
    I'm using a JQuery UI slider which has two handles (a.k.a range slider). I know how to style the first handle: .ui-slider-horizontal .ui-slider-handle {background: white url(http://stackoverflow.com/content/img/so/vote-arrow-down.png) no-repeat scroll 50% 50%;} But how do I style the second handle differently? Using Firebug I can see Jquery does not uniquely identify each handle: <div id="hourlyRateSlider" class="ui-slider ui-slider-horizontal ui-widget ui-widget-content ui-corner-all"> <div class="ui-slider-range ui-widget-header" style="left: 26%; width: 46%;"/> <a class="ui-slider-handle ui-state-default ui-corner-all" href="#" style="left: 26%;"/> <a class="ui-slider-handle ui-state-default ui-corner-all" href="#" style="left: 72%;"/> </div> So I imagine I have to use either a CSS child selector which could be cross-browser problematic. Or I could use some JQuery trickery to add a CSS class to the second handle? Anyone done this in a neat way before?

  • Where Googlebot starts crawling?

    - by Nirmal
    Say if I register a domain and have developed it into a complete website. From where and how Googlebot knows that the new domain is up? Does it always start with the domain registry? If it starts with the registry, does that mean that anyone can have complete access to the registry's database? Thanks for any insight.

  • WYSIHAT Installation - not saving photos - Ruby on Rails

    - by bgadoci
    I just successfully installed WysiHat in my rails blog. Seems that the 'add a picture' feature is not working. It successfully allows me to find and select a picture from my desktop but upon clicking save, it does nothing. I also have Paperclip successfully installed. I am wondering if this may have something to do with it. Perhaps Paperclip is getting in the way, or, perhaps I need to connect Paperclip and WysiHat somehow. Any ideas? (let me know if I need to post any code).

  • All Countries States Cities and Zipcodes in a Application

    - by Rishav Rastogi
    Is there a way getting all countries, states,cities zipcodes/ in one single database. I have been looking all over. I discovered geonames.org, which has I guess all of the content. But there is no way to fetch that data directly. I am using rails. If there any helpers or Plugins, it'd be great. It would be awesome if there is a complete resource in any parsable format which I can use to get this database in place. Please recommend if you any thanks I do have the iso country code list but no States for some countries. Thanks in advance

  • Displaying most popular posts on my blog - Ruby on Rails

    - by bgadoci
    I have created a simple blog application using Ruby on Rails, both of which I am new to. I am trying to get my most 'voted' posts to display in my /views/posts/index.html.erb view. Here are the basics. I have created a votes table and successfully allow a user to 'vote' for a post on the /views/posts/show.html.erb page. When they vote, it passes '1' to the votes table and I return the vote count via ajax to the same show page. Vote belongs_to :post and Post has_many :votes. I would like to display in /views/posts/index.html.erb the post title and the amount of times it has been voted for, ordered by posts with the highest vote count. Any ideas on how to do this?

  • Django development targeting both the Google App Engine and Py2Exe

    - by bp
    I must hand in a mostly static database-driven website on a topic on my choice by the end of June as both a hosted version live on the internet and a stored version on a cd-rom. "Ease of launching" is one of the bulletpoints for evaluation of the project. (Yeah, I know.) I and my project mate are currently comparing various frameworks and technologies to help us deliver and deploy this as quickly and painlessly as possible. Theoretically, by using Django, I can target the Google App Engine (which I guess would provide us reliable, free-as-in-beer hosting) or the Py2Exe system + SQLLite (which I guess would make starting the website server from disk as hard as doubleclicking on an .exe file). Sounds better than what PHP and MySQL can ever hope to bring me, right? However, we need to target both Py2Exe and the GAE. How much of the differencies between these wildly different configurations are hidden by Django? What will instead require special attention and possibly specialized code on my end?

  • Playing flash (.flv) videos on the web in a way that portable devices can view them

    - by Evan
    A friend of mine has created a movie for my site, it's in .flv format. I've heard of the popular flash player called flowplayer, but I have a bad feeling such a player will not work on the ipad and other devices which do not support flash. Is there a way to play a video in the flash format through a non-flash player so that the content can be viewed on all devices? I'm open to any ideas. Perhaps I may even need to convert the video to another format somehow. Thanks for any help, Evan

  • How Gridview co-operates with ObjectDataSource?

    - by sanjuro
    Hi, how Gridview co-operates with ObjectDataSource internally? When you set DataSourceID of GridView, assigned ObjectDataSource take care of such things as paging and sorting, but i don't have full control above databinding itself, on the other side when i set datasource of gridview in code-behind: protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { testGridView.DataSource = testObjectDataSource.Select(); testGridView.DataBind(); } } Now i have full control, but i have lost the advantage of comfort sorting and paging. And that co-operation between ObjectDataSource and Gridview became mystery for me. So can anybody explain me in details how ObjectDataSource and Gridview co-operates under the hood? I want to understand it in order to write my own smart code or own gridview that will mimic this co-operation. Many thanks for answers.

  • Why "alt" attribute for <img> tag has been considered mandatory by the HTML validator .. ?

    - by infant programmer
    Is there any logical or technical reason (with the W3C validation) for making alt as required attribute .. This is my actual problem:though my page is perfect enough with respect to W3C validation rules .. Only error I am getting is line XX column YY - Error: required attribute "ALT" not specified I know the significance of "alt" attribute and I have omitted that where it is unnecessary .. (to be more elaborate .. I have added the image to increase the beauty of my page and I don't want alt attribute to show irrelevant message to the viewer) getting rid of the error is secondary .. rather I am curious to know whether is it a flaw with validation rules .. ?? I thank stackOverflow and all the members who responded me .. I got my doubt clarified .. :-)

  • Difficulties using custom control - RichTextEditor

    - by Chris
    I am working on a school project that uses ASP.NET. I found this TextEditor control ( http://blogs.msdn.com/kirti/archive/2007/11/10/rich-text-editor-is-here.aspx ) that I am trying to include but it isn't working. The error I am getting is: Error Rendering Control - TextEditor. An unhandled exception has occurred. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index. I see this error when I go Design part of the editor. I just don't understand this error at all. Also I am a lil bit confused as there is no parameter called index. :( What I have done is reference the binary in my project and then on the page I am trying to use it have registered its namespace and assembly with this line: <%@ Register Assembly="RichTextEditor" Namespace="AjaxControls" TagPrefix="rtt" %> I then go ahead and try to add the control to the page with this line of code: <rtt:richtexteditor ID="TextEditor" Theme="Blue" runat="server" /> Any help would be much appreciated. I haven't done anything like add a custom control before.

  • Amazon EC2 - network issues

    - by Algorist
    Hi, We are launching hadoop cluster on amazon ec2 and recently we are having network issues like master unable to connect to slave. We thought the reason is due to amazon throttling the network connections over a limit. So, we tried to establish a connection after a random delay from each slave node. But, that didn't help. Are there any other suggestions? Thank you Bala

  • mosso versus gogrid which is better?

    - by goodwill
    I have reasonable experience to manage my own server, so gogrid style management is not a problem. But seems mosso is a tag cheaper somewhat- except the very difficult to access compute cycles terms. Anyone could share about this would be very welcomed.

  • ajax call to servlet puzzler

    - by vector
    Greetings! I'm having a problem getting a text value of a captcha from a servlet through ajax call. When my captcha gets created, its text value is written to session, but after refreshing the image itself though ajax call, I only get one old value of the text. Refreshing the image itself works ok, but I'm stuck getting the correct values from the session on subsequent call. On page reload I get both the new image and its new text value, no joy with ajax though. This works great for the image refresh: $("#asos").attr("src", "/ImageServlet?="+((new Date()).getTime()) ) This call to another method to get text value gives me old stuff: $.ajax({ url:"checkCaptcha", type:"GET", cache: false, success: function( data) { alert(data); } }); Any feedback will be appreciated. ps: here's the meat of the method getting the call: PrintWriter out = response.getWriter(); response.setContentType("text/html"); response.setDateHeader("Expires", 0 ); // Set standard HTTP/1.1 no-cache headers. response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate"); // Set IE extended HTTP/1.1 no-cache headers (use addHeader). response.addHeader("Cache-Control", "post-check=0, pre-check=0"); // Set standard HTTP/1.0 no-cache header. response.setHeader("Pragma", "no-cache"); out.print( request.getSession( ).getAttribute("randomPixValue") ); out.close();

  • Creating meaningful routes in wizard style ASP.NET MVC form

    - by R0MANARMY
    I apologize in advance for a long question, figured better have a bit more information than not enough. I'm working on an application with a fairly complex form (~100 fields on it). In order to make the UI a little more presentable the fields are organized into regions and split across multiple (~10) tabs (not unlike this, but each tab does a submit/redirect to next tab). This large input form can also be in one of 3 views (read only, editable, print friendly). The form represents a large domain object (let's call it Foo). I have a controller for said domain object (FooController). It makes sense to me to have the controller be responsible for all the CRUD related operations. Here are the problems I'm having trouble figuring out. Goals: I'd like to keep to conventions so that Foo/Create creates a new record Foo/Delete deletes a record Foo/Edit/{foo_id} takes you to the first tab of the form ...etc I'd like to be able to not repeat the data access code such that I can have Foo/Edit/{foo_id}/tab1 Foo/View/{foo_id}/tab1 Foo/Print/{foo_id}tab1 ...etc use the same data access code to get the data and just specify which view to use to render it. My current implementation has a massive FooController with Create, Delete, Tab1, Tab2, etc actions. Tab actions are split out into separate files for organization (using partial classes, which may or may not be abuse of partial classes). Problem I'm running into is how to organize my controller(s) and routes to make that happen. I have the default route {controller}/{action}/{id} Which handles goal 1 properly but doesn't quite play nice with goal 2. I tried to address goal 2 by defining extra routes like so: routes.MapRoute( "FooEdit", "Foo/Edit/{id}/{action}", new { controller = "Foo", action = "Tab1", mode = "Edit", id = (string)null } ); routes.MapRoute( "FooView", "Foo/View/{id}/{action}", new { controller = "Foo", action = "Tab1", mode = "View", id = (string)null } ); routes.MapRoute( "FooPrint", "Foo/Print/{id}/{action}", new { controller = "Foo", action = "Tab1", mode = "Print", id = (string)null } ); However defining these extra routes causes the Url.Action to generate routs like Foo/Edit/Create instead of Foo/Create. That leads me to believe I designed something very very wrong, but this is my first attempt an asp.net mvc project and I don't know any better. Any advice with this particular situation would be awesome, but feedback on design in similar projects is welcome.

  • Centering a percent-based div

    - by Sarfraz
    Hello, Recently, a client asked that his site be percent-based rather than pixel-based. The percent was to be set to 80%. As you guys know, it is very easy to center the container if it is pixel-based but how do you center a percent-based main container? #container { width:80%; margin:0px auto; } That does not center the container :(
