Trim those Textbox Values Ex: TextBox1.Text.Trim while inserting those values and Checking for Duplicate Data.

Take Backup of your Database and Restore that in his System.

use DateTime.Now.ToString("hh:mm:ss")

you can use CheckBoxList instead of creating Checkbox Dynamically.. and for CheckBoxList you can Bind the values form Database.. and onclick of OK, you can loop through CheckBoxList.Items.Count to check which is Selected and You can take only Selected Values..

Use document.getElementById ("<%=TextBox1.ClientId%>").value

give some error message for your required field Validator like rfv1.ErrorMessage ="Some Message"

try this one... Dim strcomputername As String Dim host As System.Net.IPHostEntry host = System.Net.Dns.GetHostEntry(Request.ServerVariables.Item("REMOTE_HOST")) strcomputername = host.HostName
