ISAM error

Hello Again.. i have yet another question.. BTW, you all have been very kind to offer assistance.. I have an error message that reads the following:

Server Error in '/6152' Application.
--------------------------------------------------------------------------------

Could not find installable ISAM.
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.

Exception Details: System.Data.OleDb.OleDbException: Could not find installable ISAM.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

<%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

Version Information: Microsoft .NET Framework Version:1.0.3705.209; ASP.NET Version:1.0.3705.0

I am trying to connect to an access db using the following code:

<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.OleDb" %>
<script Language="c#" runat="server">
void Page_Load(object sender, EventArgs e){
OleDbConnection objConnection;
OleDbDataAdapter objCommand;
string strConnect;
string strCommand;

DataSet DataSet1 = new DataSet();
strConnect = @"Provider=Microsoft.Jet.OLEDB.4.0;";
strConnect += @"DataSource=C:\Inetpub\wwwroot\campus.mdb;";
strConnect += "Persist Security Info=False";

strCommand = "SELECT vtpdomain FROM VLANs";

objConnection = new OleDbConnection(strConnect);
objCommand = new OleDbDataAdapter(strCommand, objConnection);
objCommand.Fill(DataSet1, "VLANs");
DataGrid1.DataSource=DataSet1.Tables["VLANs"].DefaultView;
DataGrid1.DataBind();

}
</script>

<html>
<head>
<title>Data Grid example</title>
</head>
<body>

<asp

ataGrid id="DataGrid1" runat="server" />
</body>
</html>

Any suggestions? Thanks in advance!

This is being run on your local system I assume. You don't seem to have the DB drivers installed properly or at all.

Do a search at http://www.microsoft.com for "MDAC".

I believe they are up to version 2.7. Install that and try again.
