Call a .NET component from an ASP page - Error: Server.CreateObject Failed - 800401f3

Yes, I ran sn with /codebase to create the tlb file.

Could you explain this more or what steps I should take to verify?

" Also, if the ID specified for the anonymous user in IIS doesn't match the ID of the user the com+ client was exported to impersonate, it will show that error. "

Also how can I be sure my asp page can find my dll?

Does it need to be in the same directory?

I put it in a directory called bin. I didn;t register the dll, because I didn't think it was necessary (regsvr32 myObject.dll)

jp,
It's been a few years since I've done this. Lemme parallel you in doing sdome research. Hopefully some other experts can pitch in.

Ok....when I run the following I get a return of 'True' for file found, but then a CreateObject Error:

  Dim fileObject
       Set fileObject = Server.CreateObject("Scripting.FileSystemObject")
       Response.write fileobject.FileExists("C:\Program Files\Numara Software\Numara Track-It! 8\Web Add-On\Web\Scripts\TIWebPortal\ClassLibraryPrintWorkOrder.dll")

        Dim Obj
        Set Obj = Server.CreateObject("ClassLibraryPrintWorkOrder.Class1")
        Obj.Print(rsWorkOrder("WOID").value)
       
I believe that I am calling it correctly, here is code from my class1.vb file:
Imports System.IO
Imports System.Data
Imports System.Data.Sql
Imports System.Data.SqlTypes
Imports Microsoft.SqlServer.Server
Imports System.EnterpriseServices

<Assembly: ApplicationName("ClassLibraryPrintWorkOrder")>
<Assembly: ApplicationActivation(ActivationOption.Server)>
<Assembly: ApplicationAccessControl(False, AccessChecksLevel:=AccessChecksLevelOption.ApplicationComponent)>

Public Class Class1
 <Microsoft.SqlServer.Server.SqlProcedure()> _
Public Sub Print(ByVal wid As Int32)

--More Code---

End Sub

MY PROBLEM IS:
After I build my .dll from Visual Studio 2005 I do not see my dll in the registry. I am trying to build the dll on a dev machine (with success) and then copy it to a webserver to instantiate from....how to I properly register my dll?

Anyone? Thanks.

I just noticed your last posts.  My window had sat for a bit.  Hopefully the answer to your latest question is in my first paragraph.  Let me know if you have a question.

b0lscott,

Yes, please give me the steps to try this test.....

Can you run the code locally (i.e. in a VBS file)?  Does the object get created when tried that way?

Let me know if you have a question about any step or how this works.

I am now getting this error when I try to call a function from the .dll I compiled: (And I can see it in the registry)

ERROR:
ClassLibraryPrintWorkOrder error '80004003'

Object reference not set to an instance of an object.

VB CLASS CODE:
Imports System.IO
Imports System.Data
Imports System.Data.Sql
Imports System.Data.SqlTypes
Imports Microsoft.SqlServer.Server
Imports System.EnterpriseServices
<Assembly: ApplicationName("ClassLibraryPrintWorkOrder")>
<Assembly: ApplicationActivation(ActivationOption.Server)>
<Assembly: ApplicationAccessControl(False, AccessChecksLevel:=AccessChecksLevelOption.ApplicationComponent)>
Public Class Class1
Public Function Print() As String
Dim pr As String = System.Configuration.ConfigurationManager.AppSettings("PrinterName").ToString
Return pr
End Function
End Class

ASP CODE:
Dim Obj
Dim val
Set Obj = Server.CreateObject("ClassLibraryPrintWorkOrder.Class1")  
val = Obj.Print()
Response.Write(val)

I'm glad I could help.  Thanks for the grade, the points and the fun question.

Likewise. Wish I could have helped more.
