Default Why do I keep getting a blank page?

Im trying to implement the example in CH2 on page 61 in the ASP.NET 1.1 Book. All this example does is extract some data from an access database table and puts it into a datagrid on the web page.

My problem is every time I run this, it just gives me a blank page. It seems to compile and run with out any errors. I have copied the code right out of the book and just substituted a database that I had saved on my C drive instead of using there database.

Can anyone here help me with this? Does anyone have any suggestions or ideas? Im starting to pull my hair with this already.
Here is the code.

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="WebForm1.aspx.vb" Inherits="DataControlCH2.WebForm1" debug="True"%>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.Oledb" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<script language="vb" runat="server">
Sub Page_Load(Sender as Object, E as EventArgs)
    Dim myCNN as OleDbConnection
    Dim objCommand as OleDbDataAdapter
    Dim mySQL as string
    Dim strConnect as string
    Dim DataSet1 as DataSet
    strConnect= "Provider=Microsoft.Jet.OLEDB.4.0;"
    strConnect+= "Data Source=C:\Access Work\CompanyDatabase.mdb;"
    strConnect+= "Persist Security Info=False"
    mySQL= "Select SSN,FName,LName from Employee"
    myCNN= New OleDBConnection(strConnect)
    objCommand=New OleDBDataAdapter(mySQL,myCNN)
    objCommand.Fill(DataSet1,"Employee")
    DataGrid1.DataSource=DataSet1.Tables("Employee").D efaultView
    DataGrid1.DataBind()
End Sub
</script>

Try this and see if it fixes the problem:

1) Open a command window. (Click Start, click Run, type cmd, and then click OK.)
2) Navigate to the directory of the Aspnet_regiis.exe version you want to use. Remember that each version of the .NET Framework comes with its own version.

The file is usually located in the following directory:
for XP c:\windows\Microsoft.NET\Framework\<versionNumber>
for 2000 c:\winnt\microsoft.net\framework\<versionNumber>

Then type aspnet_regiis.exe -i

Also note that setting the height of the datagrid might not display all of the table.

Thanks for the help.

I ran that regiis.exe and it successfully installed ASP.NET 1.1.
But it still did process the aspx page correctly.
When Installed IIS and Visual Studio about a year ago. From I remember I installed the whole Visual Studio first and now I found out that the IIS needs to be installed first.
Do you think I should uninstall both IIS and Visual Sudio and re-install them both. Starting with the IIS first? Do you think that might be causing the preblem?

Also do you know if I need any addition Service Packs?
