One way to do implement this functionality, that whenever a user login make an entry in DB as a loggedin user, once another user try to login with same user, allow to him for login but at the same remove the netry fro first user, and on evry postback check from whether the user has entry in db, if not then make him logout.
Its better I think if a user has logged in from one pc then dont allow from other pc , just show a message a user has already loggedin.

Yes I am agree with you brij. Other wise its unnecessary hitting of DB on every post back which impact badly on performance.

thank u sir,
i was doing the same as you are saying.and i am entering browser name also in my loginentry table(temp table).
so that suppose if user login from ie browser and now he opens new ie and enter login page of application then user should not have login page because user has logged in once and it shows direct user home page.but if he enter login url in mozilla or any other browser then he should have login page.
but at the same time if i am opening my login page from another system then again user home page is displaying.but it should be login page.

You should also store the IP of the system along with the browser.So the you can check from which system user is trying to login.If request comes from another Ip then dont allow to be logged in.
To get the IP of the client system, you can get using srever variables as Request.ServerVariables["REMOTE_ADDR"]

thanks sir
i tried your suggestion.but problem was same.if i am login from pc1 and at the same time i am trying to login from another pc then both are working while according to my requirement second should be on login page.that means both ip of the system are same is it possible? on the page load i am doing this.
string ipaddress = Request.ServerVariables["REMOTE_ADDR"];
if (usr_val.Tables.Count > 0)
{
if (usr_val.Tables[0].Rows.Count > 0)
{
string ip = usr_val.Tables[0].Rows[0]["ipaddress"].ToString();
HttpBrowserCapabilities bro = new HttpBrowserCapabilities();
bro = Request.Browser;
if(ip==ipaddress )
{
if (bro.Browser.ToString() == expl.ToString())
{
Session["Roles"] = "Admin";
Session["customer"] = usr_val.Tables[0].Rows[0]["userid"].ToString();
Session["sessionid"] = usr_val.Tables[0].Rows[0]["sessionid"].ToString();
Response.Redirect("Admin/AdminHome.aspx");
}
}
}
}
is there another way for take the ip of client system?

Hello Guys....
I am trying to Bind DropDownList with enum as follows.
cmbFromShape.DataSource = Enum.GetValues(typeof(KavirDiam.Common.Shape));
cmbFromShape.DataBind();
Following is my enum:
public enum Shape
{
Any,
Round,
Princess,
Emerald,
Asscher,
CushionBrilliant,
CushionModify,
Pear,
Radiant,
SQRadiant,
Heart,
Marquise,
Oval
}
While getting Selected Item/Value/Index it is always...returning me 'Any' i.e first member.
I am not able to get the value of selected member.

Because you need to give the value as weel for the dropdown list.
Try This :
foreach (Shape shp in Enum.GetValues(typeof(Shape)))
{
ListItem Lstitem = new ListItem(Enum.GetName(typeof(Shape), shp), shp.ToString());
DropDownList1.Items.Add(Lstitem );
}
I have found few things over here also.
How do you bind an Enum to a DropDownList control in ASP.NET?[^]
Thanks !

1. You don't need to shout!
2. You want to see coding then find a place where it is written! I would suggest, you write yourself and then see it!
If you have tried something and have specific issues/problems, post here.

Hi,
Can somebody help me to Implimeting indian regional languages(like punjabi,tamil,hindi etc) in asp.net web application its very urgent.
Thanks and regards

The logic behind regional language is to convert the regional text into unicode (the language supported by browser)and this can be done through language converters.
Second way to do is make .eot or .pfr files of your font and access that file in your ASP.NET page.
You have to download WEFT by which you can make eot files of your font.
Just search in Google or you can get it on Microsoft site also.
Something like:
*********************************
<style type="text/css" >
@font-face
{
font-family: AkrutiDevYoginiUnicode;
font-style: italic;
font-weight: normal;
src: url(AKRUTID0.eot);
}
</style>

My requirment is that the asp.net web apllication will chane in the laguage choosen from dropdown.
Thanks in advance
