DB Connectivity Problem
Hi
I am trying to display MS Access Data thru aspx page. But getting errors.
Code is as follows :
------------------------------------------------------------------------------------
<%@ Page Language="vb" Debug="true" %>
<%@ Register TagPrefix="wmx" Namespace="Microsoft.Matrix.Framework.Web.UI" Assembly="Microsoft.Matrix.Framework, Version=0.6.0.0, Culture=neutral, PublicKeyToken=6f763c9966660626" %>
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.OleDb" %>
<script runat="server">
Sub Page_Load(sender As Object, e As EventArgs)
'declarations
Dim conTest As OleDbConnection
Dim cmdTest As OleDbCommand
Dim rdrTest As OleDbDataReader
conTest = New OleDbConnection( _
"Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:\TestNet.mdb")
conTest.Open
cmdTest = New OleDbCommand ( "select * from Emp", conTest)
rdrTest = cmdTest.ExecuteReader
gridTest.DataSource = rdrTest
gridTest.DataBind
rdrTest.Close
cmdTest.Dispose
conTest.Close
End Sub
</script>
<html>
<head>
<title>Test of dot net for database connections - uses Test</title>
</head>
<body text="#000000" bgcolor="#ffffff">
<h1>Listing from Test accounts using dot net
</h1>
<asp:DataGrid id="gridTest" accessKey="<%# Page %>" runat="server" itemstyle-verticalalign="top" headerstyle-font-bold="true" headerstyle-backcolor="lightsteelblue" autogeneratecolumns="false" font-size="8pt" cellpadding="5" width="92%">

pretty sure you can't do this:
Code:
accessKey="<%# Page %>"
, take it out and see if it works. Why were you putting that in there?

Hi pvb
That MS Access connetivity worked using following code.
Sub Page_Load(sender As Object, e As EventArgs)
Dim conTest As OleDbConnection
Dim cmdTest As OleDbCommand
Dim rdrTest As OleDbDataReader
conTest = New OleDbConnection( _
"Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:\TestNet.mdb")
conTest.Open
cmdTest = New OleDbCommand ( "select * from Emp", conTest)
rdrTest = cmdTest.ExecuteReader
gridTest.DataSource = rdrTest
gridTest.DataBind
rdrTest.Close
cmdTest.Dispose
conTest.Close
End Sub
But now facing SQL Server connectivity problem.
Pls kindly refer to new thread
