Guys,

This piece of code to insert a new student into the DB was working perfectly, i dont know hwat i did to screw it up but maybe the error is blatantly obvious to someone more experienced.

<%@ Page Language="VB" Debug="True" %>
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.OleDb" %>
<script runat="server">

    Sub btnInsertClick(Sender As Object, E As EventArgs)

         Dim aConnection As OleDbConnection = New OleDbConnection
         Dim aConnectionString As String
         Dim aQuery As String
         aConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\Inetpub\wwwroot\records.mdb"
         aConnection.ConnectionString = aConnectionString
         Dim aCommand As OleDbCommand = New OleDbCommand
         aConnection.Open()
         aQuery = "Insert Into Students(StudentID, FirstName, LastName, EmailName, BirthDate, Pword) VALUES ('"& StudID.Text &"', '"& F_Name.Text &"', '"& L_Name.Text &"', '"& Email.Text &"', '"& D_O_B.Text &"', '"& Pword1.Text &"')"
         aCommand.Connection = aConnection
         aCommand = New OleDbCommand(aQuery, aConnection)
        
    End Sub

</script>

No error message, just when i click the submit button the password fileds clear and usually after i did that it was entered but now it doesnt enter it. Is it a problem with where i have my DB?? All my files are in the wwwroot folder and i have my DB there as well.

omg.. you cannot be serious?

a line causes an error and you just "take it out" to try to fix it?  lol.. you got some issues ahead if thats your method of solving problems.....

that line i post is what actually runs the query you are presenting the database... your code w/o it never says "do it"

and that "updatable query" error message (as i believe this is in borgs tutorials section) means that the database is in a directory which the web server doesn't have the proper permissions... which it sure in hell shouldn't since your database is sitting in the root of your web application (easily the WORST place for a database to exist)....

you gots some readin' to do... starting with here and that PM i sent you

You could make the sub actually handle something. I don't see where you call the sub when the button is clicked, but that could be me, since I just ran quickly trough it.

EDIT: Alright! I've seen it. But using the Handles.Button might be better.

My solution is easy. Build it again! Sometimes I screw up to, and rebuilding the thing from scratch is the best solution.
