Default Using Components - Beginning ASP.NET

ComponentProblemWrox


When I try and run the Hello World component in chapter 16 of the book: "Beginning ASP.NET 1.0 with Visual Basic.NET"
I get the following error:

WroxComponents.HelloVB' is not defined

What am I missing?

Here is the code for UseMyFirstComponent.aspx:

<%@ Import Namespace="WroxComponents" %>

<html>
<head><title>My First Component Example</title></head>
<body>

Our component says: <br /> <br />
<asp:Label id="label1" runat="server" />

<script language="vb" runat="server">

Sub Page_Load(Source As Object, E As EventArgs)
  Dim VBComponent as new HelloVB()
  label1.text=VBComponent.SayHello()
End Sub

</script>
</body>
</html>

Here is the code for MyFirstComponent.vb located in C:\Inetpub\wwwroot\WroxCode\ch16. I compiled it from the command line with the following .bat file


set indir=C:\inetpub\wwwroot\wroxcode\ch16\MyFirstComp onent.vb
set outdir=C:\inetpub\wwwroot\wroxcode\ch16bin\MyFirst Component.dll

vbc /t:library /out:%outdir% %indir%
pause


 to MyFirstComponent.dll in the C:\Inetpub\wwwroot\WroxCode\ch16\bin folder

MyFirstComponent.vb is below …

Namespace WroxComponents

  Public Class HelloVB
     Public Function SayHello() As String
      Return "Hello World - I'm a VB.NET component!"
    End Function
  End Class

End Namespace

********************_




I'm not using WebMatrix or VS. I'm trying to "use" the component described in chapter 16 of the book: "Beginning ASP.NET 1.0 with Visual Basic.NET"

Did you check if the dll exists under BIN folder?

If not, this could be the problem, Looks like you are missing a \ below before BIN.
set outdir=C:\inetpub\wwwroot\wroxcode\ch16\bin\MyFirstComponent.dll

Check if that helps.
