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();
}
Best Regards

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 ?
Thanks and Regards

Hello,
I have a website where customers can register for classroom training. After answering all the questions, I'd like asp.net to send a calendar notice to the users inbox. From what I've seen, I have to attach an ics file that represents an iCalendar. I'm successfully sending emails to the customers...I just have to find out how to add the ics attachment and set the parameters (e.g. remind the customer 24 hrs prior to training day, day of training, etc...).
My users are using Outlook 2003 and greater. I'm using asp.net 2.0. Any ideas?

Hi all,
I have a GridView (grv) that contain a HyperLinkField ( "MyLink" ).
I have a DataTable (dt) that contain data for GridView. ( I don't use SqlDataSource )
When i click "MyLink", "MyLink"'s NavigateUrl will be Default.aspx?id=param1&idU=param2.
How could i do that?
|
|
|
|

You can do it easily in Mygridview_OnRowDataBound event. While binding the grid this event fire on row level then just get the id & idU from other cell and build url string then set it to the Your Link NavigateURL.
