Hi,I am having problem in displaying the returned value from one function.I write one function for creating db connection,in that function I returned the string value of username.I want to display the string username value in different label through a button click event.What is the C# ASP.NET syntax ?Can any one help me..?Thanks.......

Hi,You gave one syntax know,that is not working, Again I have some error...So,I discribed my problem here again ....
In that function I return one string value,I want to display the string value in another project by calling the dll of this.How can I display..?
Could you tell the code is correct or not for creating the db connection ?

public string FuncAuthentication(string txtusername)
{
string conn ="server=IDC-DEVELOPMENT ;uid=sa;pwd=password;database=SCBNotis";
string comm = "Select ADMINUSERID from ADMIN where ADMINUSERID='admin'";
SqlDataAdapter da =new SqlDataAdapter(comm,conn);
DataSet ds = new DataSet();
da.Fill(ds,"ADMIN");
DataTable dt = ds.Tables[0];
DataView dv;
dv = ds.Tables[0].DefaultView;
foreach(DataRow dr in dt.Rows)
{
txtusername=(dr [ "ADMINUSERID" ].ToString ( ));
}
return txtusername.ToString();
}

here, let me clean up your code so that it more cleanly does what you have it doing now

publicstring FuncAuthentication(string txtusername)
{
return "admin";
}

you're missing the point, which is that you're sql query isn't going to work.
It is always going to return either null or "admin"
