1) I have a .NET Web Application called "Lesson18b" under
"C:\Inetpub\wwwroot\Lesson18b".
2) I have one Web Form on this Lesson called "Form18b.aspx"
3) In this same Folder under Inetpub I have the famous NorthWinds
Access Database called "FPNWIND.MDB"
4) I add an OleDBConnection called OleDBConnection1. I set the "New
Connection" Properties to: Provider is "Microsoft Jet 4.0 OLE DB
Provider". Database Name is "FPNWIND.MDB". User name is
"Admin". Blank Password is checked. I test the connection and it
states that the "Test Connection Succeeded". I choose not to
include a password in the connection string.
5) I then add an OleDBCommand called OleDBCommand1. I set the
connection to OleDBConnection1. For the command text I select the
"..." and when asked, I add table "Customers". I move "All
Columns" to the grid below, producing the SQL "SELECT
Customers.* FROM Customers". When I right click the bottom
grid and choose "Run", it fills the grid with data. So far, so
good.
6) Back on the form Form18.aspx I add a text field called
"txtResults" and a command button called "Button1".
7) Double-clicking on "Button1", I add the following lines of
code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim dr As OleDb.OleDbDataReader
OleDbConnection1.Open()
dr = OleDbCommand1.ExecuteReader
While dr.Read
txtResults.Text = dr.GetValue(0)
End While
End Sub
8) When I build, then run the application, and click on "Button1",
I get the following error:
We can't find
http://localhost/Lesson18b/Form18b.aspx
Error - Internal server error
9) If I debug the application, it bombs on the following line in
Button1:
OleDbConnection1.Open()
I'm trying to get the data to display on txtResults. This code works
fine in a regular VB App...but for some reason it will not work on this
Web VB App.
Does anyone have any ideas on why this is happening?
