Thank you Alaric. I tried it and it works. Now I would like to switch to SQL SERVER 2005 instead of SQL Server Express. How should I change the connection string? Thanks, Hezi

I try to open the SQL Server Express database file "sample.mdf" but it doesn't work. Here is the code: -------------------------------------------------------------------------- using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Data.OleDb; using System.Data.SqlClient; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //OleDb-ACCESS //-------------- //OleDbConnection con = new OleDbConnection(); //string comPath = Server.MapPath("~" + @"\") + @"app_Data\webTest.mdb"; //string coS = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + comPath; //SqlClient-SQL server express //------------------------------ System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection(); string comPath = Server.MapPath("~" + @"\") + @"app_Data\sample.mdf"; string coS = "Data Source=.\\SQLEXPRESS;AttachDbFilename=" + comPath + ";Integrated Security=True;User Instance=False;"; //OleDb-SQL server express //------------------------- //OleDbConnection con = new OleDbConnection(); //string comPath = Server.MapPath("~" + @"\") + @"app_Data\sample.mdf"; //string coS = "Provider=SQLOLEDB.1;" + "Data Source=" + comPath; con.ConnectionString = coS; con.Open(); } } -------------------------------------------------------------------------- 1. Code OleDb-ACCESS (commented) works OK. 2 . When I run the code in section: SqlClient-SQL Server express, I get error: Server Error in '/myWeb/trySqlServer' Application. -------------------------------------------------------------------------- CREATE DATABASE permission denied in database 'master'. An attempt to attach an auto-named database for file C:\MyPrograms\web\trySqlServer\app_Data\sample.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I have a matrix of checkboxes and I would like to get the id on which the mouse is over. I set the onMouseOver handler programmatically by the following C# code in the Page_Load procedure: checkBoxObject.Atributes.Add("onMouseOver","mouseOverHandler(this)"); The client's MouseOverHandler function (JavaScript) is: Function mouseOverHandler(this) { alert(document.getElementById(me.id)) } When I move the mouse over a checkbox I get an empty alert box. It seems that the function "mouseOverHandler " does not get the firing checkbox in the argument"me". The same code works correctly when I change the triggering event from "onMouseOver" to "onClick". 1. Why does it work with "onClick" and dose not work with "onMouseOver" 2. How can I make it to work with "onMouseOver" Thank you Hezi
