Deleting rows in Access database table

G

Guest

I get an error message when deleting rows from a table in Access database.

My understanding is that the error message relates to the sharing of the
Inetpub and the wwwroot directory.

While I have set the directories to "Share" in the properties window, it
still does not allow row removal.

I'm running Microsoft Windows XP, Professional, Version 2002, Service Pack 1.

The code is as follows and the error message is after it.


***************** Start Code ********************
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.Oledb" %>

Sub Page_Load(Sender as object, e as EventArgs)
if not isPostBack then

Dim Con As OleDbConnection = New OleDbConnection
Dim DA As OleDbDataAdapter = New OleDbDataAdapter
Dim ConnectString, delCmd, x as String

x = Server.Mappath("\ASPClass\FinalProj\DB.mdb")

ConnectString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & x

Con.ConnectionString = ConnectString


delCmd = "DELETE * FROM ORDERS"

DA.DeleteCommand = New OleDbCommand(delCmd, Con)
Con.Open
DA.DeleteCommand.ExecuteNonQuery()

end if
End Sub

DELETE * FROM ORDERS

I believe this is incorrect.

Try "DELETE FROM ORDERS"

Thanks for your comments.

I changed the SQL to "DELETE FROM ORDERS" but still get the same error.

I have been led to believe that the problem is not with the SQL, but is file
sharing related.

All of the directories within the directory path of the Access database have
been set to "Share the folder" with the permissions set to "Full Control" via
the directory's Properties Window. But to no avail. (The Database resides
in the c:\Inetpub\wwwroot\ASPClass\FinalProj directory.)

I'm running Microsoft Windows XP, Professional, Version 2002, Service Pack 1.

Is there aonther newsgroup which is focused on file sharing issues?

Thanks,

Mark

Sharing has nothing to do with web apps -- just networking. You want
to right-click on either the folder containing the DB or the DB file
itself and choose "Properties". On the security tab, you want to give
read/write permissions to either "Everyone" (not recommended for
production environments but OK for local projects) or the asp.net
account, usuall called "Launch IIS Process Account
(machinename\IWAM_machinename).

Cheers,
