I have a web application (SnapshotServer) which uses a WebBrowser control to take a snapshot images of a web page.
I use a WebBrowser control within SnapshotServer to navigate to a entry page of a secure web application (ImageHost) and then redirects me to my required page.The ImageHost application is protected by FormsAuthentication, which uses cookies. The entry page I navigate to takes care of logging me in - which will create an Auth cookie.
Once a response is generated from the ImageHost, I convert the result within the WebBrowser control to an image.
Issue:
When I run SnapshotServer on my PC (Windows 7, IE8), using IIS7, and navigate to ImageHost on my development server (Windows 2008 R2, IE8), the result is as required - I'm logged into ImageHost and redirected to the page I want an image of. When I run SnapshotServer on any Windows 2008 R2 server, using IIS7, and navigate to ImageHost on my development server (Windows 2008 R2, IE8), the result is not as required - ImageHost fails to log in - so my image is of the login page. The reason it fails to log in is that it isn't creating an Auth cookie.
So I'd like to know if anyone can tell me why the WebBrowser control, when run from a Windows 2008 server, cannot create cookies.
I want to create a custom attribute to check if the browser has cookies and javascript enabled. I'm guessing I would create a ActionFilterAttribute that would redirect to a controller action to load a page to check cookies and javascript on the client side. If they are enabled then it would redirect to the desired action, otherwise display an error message. Is this a correct approach or is there a better way to do this?
I am using asp.net with c#.My issue is this that I am setting cookies to check that the same user is returning or not but user are returing from the same machine with different browser. Is their any alternate I would know that same machine user had visited my site.
The Request.Browser.Cookies property (of type bool) attribute stores information whether client's browser supports cookies and whether or not they are enabled.How reliable is the property Request.Browser.Cookies? Is it guaranteed to be correct ? Or should I rather implement redirection technique suggested by Software Monkey in this question?Please note: This in not a question "are cookies reliable" ? This is a question: "Is the information whether users browser accepts cookies reliable?"
This thing has just came to my head and I wanna share it.Note : I could easily test it but I am being lazy here to see if anybody has ever experienced something like that before.Let's assume that I have a web site which built-in membership structure of asp.net has been implemented on. What will happen to asp.net membership if the client browser blocks cookies? Does framework throw an exception when a user tries to log in or do something else?
As we know that closing a browser will delete cookie if the cookie does not set an expired date. However, I want to set an expired date to all of my cookies and also delete them when browser closed.
But how can I read each one of them in JavaScript because I want to populate the text boxes next time the user come to the form? I have tried this but it does not work:
var cookieName = ReadCookie("Name"); document.getElementById('txtName').value = cookieName;
Edit with Answer:
I used this code.
<script type="text/javascript"> function getCookie(c_name) { if (document.cookie.length>0) { c_start=document.cookie.indexOf(c_name + "="); if (c_start!=-1) { c_start=c_start + c_name.length+1; c_end=document.cookie.indexOf(";",c_start); if (c_end==-1) c_end=document.cookie.length; return unescape(document.cookie.substring(c_start,c_end)); } } return ""; } function checkCookie() { Name = getCookie('Name'); Surname = getCookie('Surname'); Email = getCookie('Email'); Company = getCookie('Company'); Title = getCookie('Title'); if (Email!=null && Email!="") { //Populate the text boxes. document.FormName.txtName.value = Name; document.FormName.txtSurname.value = Surname; document.FormName.txtEmail.value = Email; document.FormName.txtCompany.value = Company; document.FormName.txtjob.value = Title; } } </script>
And called the checkCookie() function like so from the window.onload
I would like to set the Login which will log auto when he return to site, if the user hasent logged off the site.and if he enter the site again he'll be logged in already.
I'm handling cookies using JavaScript to store some values in my asp.net web application.I use document.cookie to save some values (converted into a lengthy string). But i want that value to be accessible across all the pages in my application.When i try to get that value from a different page, i get the values pertaining to the document in the current URL.
In short i save the value in the cookie in http://myapp/doc1.aspx and want to retrieve it in http://myapp/doc2.aspx
So is document.cookie is pertaining to a single document scope? How can i save/read cookies across the site?
Update.This is how i get and set cookies
function getCookie(c_name) { try{ [code]...
But i'm getting different values for the cookies in different pages.
I have been experimenting with code that will clear all of the cookies in an HttpContext.Response.Initially, I used this:
DateTime cookieExpires = DateTime.Now.AddDays(-1); for (int i = 0; i < HttpContext.Request.Cookies.Count; i++) { HttpContext.Response.Cookies.Add( new HttpCookie(HttpContext.Request.Cookies[i].Name, null) { Expires = cookieExpires }); }
this will error with an OutOfMemoryException because the for loop never exits - each time you add a cookie to the Response, it also gets added to the `Request.
I know that if I have set a cookie on a previous request, it will show up in my Request.Cookies collection. I want to update my existing Cookie. Are the cookies from my Request.Cookies collection already copied to my Response.Cookies collection? Do I need to add a new cookie with the same key using Response.Cookies.Add(), or do I need to use Response.Cookies.Set()?
In Visual Studio 2008 Express there is no folder browser to allow me to select a destination folder for downloading.
There is a FileUpload, but it requires a filename. I just want to select a folder only, and get its full path information.
In Windows API, there is a folder browser that I called in MS Access using VBA code.
Can someone supply me the code or tell me how to generate a folder browser to select a destination folder for downloading data to !! I would like it in VB.
I do have an .exe that generates a browser, but you can't run it on a website.
I'm trying to learn Visual Web Developer 2008 and web site design. I have created a website with a 'contact us' section and it is working fine. On this page I have appx 6 Input text boxes but lots of graphics and such on the page. I'm trying to figure out how to get started building a simple version of the same page so that blackberries, android, iphone, etc... could fill out and submit the form. I don't want anything fancy on the form, just labels and text boxes.
I'm been searching the web and everything leads me to add a mobile web form to my project but in VWB 2008 there is no such thing (at least that I can find)
how to prepopulate an outlook email's body and subject using the mailto: form of an anchor tag.
What I'd like to see is some examples of Outlook automation code on the server, that creates an Outlook template file (.ost?) and binary writes it to the browser - the browser recognising the extension and firing up outlook with the template.
This is internal and the user will definitely have Outlook.
When a .NET server control is rendered in a browser it is rendered as a html control. Then how a browser differentiate between a server control and a html control. If the two control rendered as same then how server side events fire for a server control? If u say by using runat="server" attribute then also we can add runt="server" for html controls to work at server side... so then how these are recognized?
