MVC :: How To Create Attribute To Check If Browser Has Cookies And Javascript Enabled
May 27, 2010
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'm opening new window from Code Behind for that I'm using Code :
Dim newWin As String = ("<script language='javascript'>" + "window.open('msgstat.aspx' , 'Print', 'height=200, width=220, menubar=no, toolbar=no, scrollbars=no, resizable=no'); </script>")
ClientScript.RegisterStartupScript(Me.GetType(), "pop", newWin)
Now, how can I check from codebehind that Browser's Popup Blocker is enabled or Disabled and show such message.

I want to check if a mobile browser has javascript enabled before displaying a page to the user. The code I've found from my research is:
System.Web.HttpBrowserCapabilities browser = Request.Browser;
Response.Write(browser.EcmaScriptVersion.ToString());
So to ensure that javascript is enabled on a browser, you need to check wheather the returned valued is either equal to or bigger than 1. This works on normal browsers, but when I test it on my phone the returned value is always 0.0, no matter if my javascript is enabled or disabled. Is there a way to check if javascript is enabled on a mobile browser or will the browser handle the incapability on it's own?

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 know how to write/create cookies in JavaScript.
//Create the cookies
document.cookie = "Name=" + Name + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Surname=" + Surname + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Number=" + Number + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Email=" + Email + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Country=" + Country + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Company=" + Company + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Title=" + Job + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
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
<SCRIPT TYPE='text/javascript' LANGUAGE='JavaScript'><!-- //
window.onload = initPage;
function initPage()
{
checkCookie();
}
//-->

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.

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' <!DOCTYPE html PUB'.
There are tons of references for this error message on the Web, but I can't figure it out. The problem is that the application works fine when I run it locally or when deployed to other servers. There is just one server where I get this error during a post back from an Update panel (it is supposed to populate and open a popup panel). There is no Response.Write() anywhere in the code and the other either. I think. The next thing I will try is install the remote debugger. In the meantime, can someone tell me how to check if server trace is enabled (IIS 6)?

My only requirement is to find a selected pdf in a folder is Reader enabled or not, more specifically if usage rights are defined in a way that allows people to add annotations (e.g. comments).
I am doing this in windows application. If I click a button, an event is triggered searching a folder for PDF files. This event needs to check whether or not the PDFs in the folder are Reader enabled for comments. If they are, I need to remove the comment usage rights or revert the PDF back to its original version.
My code can only find PDF files in the folder. I don`t know how to check if the selected PDF is comment enabled or not.
private void button1_Click(object sender, EventArgs e) {
{
string[] filePaths = Directory.GetFiles("D:myfolderpdffolder");
List<ListViewItem> files = new List<ListViewItem>();
foreach (string filePath in filePaths) {
---need to check comment enabled or not---
}
}
}

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?"

}
protected void Button1_Click(object sender, EventArgs e)
{
Label1.Text = Request.Cookies["a"].Value.ToString(); //it returns value
}
Why is this?

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?

Specifically we're making our application compatible with the Out Of Process Session State server where all types saved in session must be serializable. Is there a way to see at compile time that any type put into HttpSessionState is marked with the Serializable attribute. Something along the lines of this 'non-valid' code
public static void Put<T>( string key, T value ) where T : IsMarkedWitheSerializableAttribute
{
HttpContext.Current.Session[key] = value;
}
