I am writing my first aspx file to connect to a standalone SQL Server which is separated from the IIS webserver. The code is
<HTML>
<HEAD>
<TITLE>Store Locator</TITLE>
<script runat="server">
Sub Page_Load(ByVal Sender as Object, ByVal E as EventArgs)
if Not IsPostBack Then
Dim DBConn as OleDbConnection
Dim DBCommand As OleDbDataAdapter
Dim DSPageData as New DataSet
DBConn = New OleDbConnection("Provider=sqloledb;" _
& "server=dailyplanet;" _
& "Initial Catalog=JAVSTORE;" _
& "User Id=javtrader;" _
& "Password=rage123;")
DBCommand = New OleDbDataAdapter _
("Select * " _
& "From JAVInventory " _
& "Where ID > ((Select COUNT(ID) " _
& "From JAVInventory ) - 100)" _
& "Order By ID DESC", DBConn)
DBCommand.Fill(DSPageData, _
"RecentJAVs")
' ddlZipCode.DataSource = _
' DSPageData.Tables("RecentJAVs").DefaultView
' ddlZipCode.DataBind()
End If
End Sub
I used Visual .Net and Web Matrix and was able to connect to the sql server with the Data Connection to view the tables. However, when I use IIS or the Visual .Net debugger to run the aspx file, it get the following error.. please help..
Server Error in '/javtrade' Application.

This can be formed in two ways, one using a trusted connection, or the other being uid=; and pwd=; the login and password for sql respectively. Either version of the connection string must include the server name, which is localhost, 127.0.0.1 if on the localmachine or the actual name or ip of the server.
