<br />
 function writeCookie()<br />
    {<br />
      var txtuname=  document.getElementById('TxtBxUserName');<br />
      var txtpass=  document.getElementById('TxtBxPassword');<br />
       <br />
        <br />
        var exdate=new Date();<br />
        exdate.setDate(exdate.getDate()+15);<br />
<br />
        if(document.getElementById('CheckBox1').checked)<br />
        {<br />
          alert( txtuname.value+"="+escape(txtuname.value+"|"+txtpass.value)+";expires="+exdate.toGMTString());<br />
            document.cookie= txtuname.value+"="+escape(txtuname.value+"|"+txtpass.value)+";expires="+exdate.toGMTString();<br />
            <br />
        }<br />
        else<br />
        {<br />
            alert("Check box is not selected ");<br />
                 <br />
        }<br />
    }<br />
    <br />
    function readCookie()<br />
    {<br />
   <br />
      var txtuname=  document.getElementById('TxtBxUserName');<br />
      var txtpass=  document.getElementById('TxtBxPassword');<br />
      <br />
<br />
  if (document.cookie.length>0)<br />
  {<br />
   var  c_start=document.cookie.indexOf(txtuname.value);<br />
   //alert(document.cookie);<br />
   //alert("to search txtvalue "+txtuname.value);<br />
  <br />
      if (c_start!=-1)<br />
        { <br />
        c_start=c_start + txtuname.value.length +1 ;<br />
      //   alert(" start "+c_start);<br />
    var    c_end=document.cookie.indexOf(";",c_start);<br />
  //  alert("end "+c_end);<br />
                if (c_end==-1) <br />
                {<br />
                    c_end=document.cookie.length;<br />
    //                alert(c_end);<br />
                }<br />
           var value= unescape(document.cookie.substring(c_start,c_end));<br />
         //  alert("value "+value);<br />
           var arr = new Array(2);<br />
           arr= value.split('|',2)<br />
           alert("Username "+arr[0]);<br />
           alert("Password "+arr[1]);<br />
           txtuname.value=arr[0];<br />
           txtpass.value=arr[1];<br />
           } <br />
           else<br />
           {<br />
                 txtpass.value="";<br />
           }<br />
    }<br />
<br />
    } <br />
<br />

only thing that you have to call from page

<br />
 LoggedInButton.Attributes.Add("OnClick", "javascript:writeCookie();");<br />
 TxtBxPassword.Attributes.Add("OnFocus", "javascript:readCookie();");<br />

Hi
Sorry for late reply you can't add password frm server side check the javascript function readCookie() you have to call this function onFocus of password textbox and set the cookies when user looged in
See what you have to do
1) first of all if userName and password are correct then you have to write them in cookies ok
2) Second whenevr user starts to write his username then on pass word text box focus you have to call javascript .

<br />
protected void LoggedBtn_Click1(object sender, EventArgs e)<br />
    {<br />
         // First check enter user name and password are right or not if <br />
// they are then write the cookie <br />
       if(CheckCredentials(txtBxUserName,txtBxPassword))<br />
        if (CheckBox1.Checked)<br />
        {<br />
            HttpCookie cookie = new HttpCookie(TxtBxUserName.Text);<br />
            cookie.Values.Add("",TxtBxUserName.Text + "|" + TxtBxPassword.Text+";");<br />
            cookie.Expires.AddDays(30);<br />
            Response.Cookies.Add(cookie);<br />
<br />
    <br />
        }<br />
       <br />
    }<br />
// in page load register the java script to retrive the cookies value <br />
 TxtBxPassword.Attributes.Add("OnFocus", "javascript:readCookie();");<br />

Thanks and Regards
Sandeep

Hey sandeep its working now, but when I enter any other user name and password and then logout it is not store in cookies. Can u please tell me what might be the problem.

Ex: Suppose I first logon as varsha and password also varsha
and do login and logout and when I again login with varsha it shows by password.
But now if i logon as sandeep and password also sandeep and check the checkbox of remember me and do login it gets login but then value in the cookies are varsha.

Can we have the new value in cookies???

Sandeep Akhare11-Sep-07 1:02

11-Sep-07 1:02

<br />
HttpCookie cookie = new HttpCookie(TxtBxUserName.Text);<br />
            cookie.Values.Add("",TxtBxUserName.Text + "|" + TxtBxPassword.Text+";");<br />

It is happening because you need to store the cookies with different name see above code where i have created cookie with name USername and pass it value as "" and password . i think you are creating cookies with same name/key again check whether you are resetting the cookies you should not reset cookies.I hope you got the point Blush | :O

Re: Password in Cookies [modified]

11-Sep-07 1:20

I am implementing Logout ie When I logout all the cookies must be removed and when I login with new user name cookies should be replace with that. Here is the code:
Login.asp.cs
protected void Page_Load(object sender, EventArgs e)
{
Session["CompanyName"] = "FLAG";
txtPassword.Attributes.Add("OnFocus", "javascript:readCookie();");
}

protected void ibtnLogin_Click(object sender, ImageClickEventArgs e)
{
clsFunctions cs = new clsFunctions();
DataSet ds = new DataSet();
String str = "Select LoginId,LoginName ,Password from tbUser where LoginName= '" + txtId.Value + "' and Password ='" + txtPassword.Value + "' and UserGroupId= 1";
ds=cs.Return_Dataset(str,cs.connectionDBcentral() );
lblMessage.Visible = false;
if (ds.Tables[0].Rows.Count > 0)
{
HttpContext.Current.Cache.Insert(txtId.Value, ds.Tables[0].Rows[0][0]);

if (chkRememberMe.Checked)
{
HttpCookie RememberMe = new HttpCookie("RememberMe");

RememberMe.Values.Add("", txtId.Value + "|" + txtPassword.Value + ";");
RememberMe.Expires.AddMinutes(2);
Response.Cookies.Add(RememberMe);

Session.Add("Check", "On");
Session.Add("Country", "0");
Session.Add("logname", txtId.Value);
Session.Add("loginId", ds.Tables[0].Rows[0][0]);
Response.Redirect("Home.aspx");
}
else
{
HttpContext.Current.Cache.Insert(txtId.Value, ds.Tables[0].Rows[0][0]);
Session.Add("Check", "On");
Session.Add("Country", "0");
Session.Add("logname", txtId.Value);
Session.Add("loginId", ds.Tables[0].Rows[0][0]);
Response.Redirect("Home.aspx");
}
}
else
{
Session.Add("Check", "Off");
lblMessage.Text = "Invalid LoginName and Password";
lblMessage.Visible = true;
}
}

JavaScript function:

function readCookie()
{
var txtuname= document.getElementById('txtId');
var txtpass= document.getElementById('txtPassword');
if (document.cookie.length>0)
{
var c_start=document.cookie.indexOf(txtuname.value);

if (c_start!=-1)
{
c_start=c_start + txtuname.value.length +1 ;
var c_end=document.cookie.indexOf(";",c_start);
if (c_end==-1)
{
c_end=document.cookie.length;
}
var value= unescape(document.cookie.substring(c_start,c_end));
var arr = new Array(2);
arr= value.split('|',2)
alert(arr[0]);
// alert("Username "+arr[0]);
// alert("Password "+arr[1]);
txtuname.value=arr[0];
txtpass.value=arr[1];
}
else
{
txtpass.value="";
}
}
}

Logout.aspx.cs

protected void Page_Load(object sender, EventArgs e)
{
HttpContext.Current.Cache.Remove(Session["logname"].ToString());
Session["Check"] = "off";
//Cache.Remove("RememberMe");
//HttpCookie RememberMe = new HttpCookie("RememberMe");
//RememberMe.Expires = DateTime.Now;

Response.Cookies["RememberMe"].Expires=DateTime.Now;

Session.Abandon();
FormsAuthentication.SignOut();
Response.Redirect("Login.aspx?action=SessionExpired", true);
}

I am not getting how to do.

Thanks again.

Hi All,
I want to change the number format to Local Culture in Java Script by reading culture value from Web Config. I have a function like below,but the following reads the culture from system settings,instead of this i need a code which reads the Culture from the webconfig and changes the format according to that.

function changeculture()
{

var num = new Number(document.getElementById("arun").value);
document.getElementById("arun").value = num.toLocaleString();
}

i think you want to store that data only in Dataset not in database. You can put that it quite simple .. How much data is present in the dataset ? (how many users data present in dataset a perticular instant ) if it is only one then you can change the data at any time ... Whats the problem are you facing ?
