I guess I should be directing these questions to Stephen Walther directly
but I am not sure how to contact him.
In ASP.NET Unleashed (pp. 274-275) There is a sample
<Script runat="Server">
Sub Page_Load
Dim strFeatured As String
Dim RanNum As New Random
Dim ctlControl As Control
strFeatured = "Featured" & RanNum.Next( 1, 3 ) & ".ascx"
ctlControl = LoadControl( strFeatured )
Ctype( ctlControl, FeaturedProduct ).BackColor="Orange"
plhFeatured.Controls.Add( ctlControl )
End Sub
</Script>
<html>
<head><title>DisplayFeaturedProductCodeBehind.aspx</title></head>
<body>
<asp:PlaceHolder
id="plhFeatured"
Runat="Server" />
</body>
</html>
When I try to run it I get the following error. Any idea what is wrong? I
have recompiled the FeaturedProduct.vb code behind and made sure that it is
in the bin directory but I still get the error.
