My Serviced component doesn't expose any methods!

My Serviced component doesn't expose any methods!

Hello,
PLs help:
I have a component written in VB2005. It contains a class that inherits 
System.EnterpriseServices.ServicedComponent.
The class contains a default constructor without any parameters or 
implementation.
It also contains several public instance methods.
The component installs as a COM+ application under Component Services on an 
XP machine, with all interfaces present.
However, the class interface (_classname) exposes no methods at all!
Could anyone please advice on how to address this.

Thankx in advance!

RE: My Serviced component doesn't expose any methods!

Hi Karre,

From your description, you're encountering some error when try calling a 
.NET serviced component ,correct?

Based on my experience, for serviced component, you can check the following 
things to see whether there is anything incorrect:

** the attributes and class/method setting in the serviced component 
asssembly. Have you marked the class and methods as public, whether the 
class is COM visible or have you apply a strong-name for the assembly

** the deployment of the serviced component assembly. Whether you've added 
the assemly into GAC(better to do this), and did you use regsvcs to 
explicitly install it(any error or warning occurs)?

Here is a simple test serviced component I've used which worked correct on 
a local XP box:

================================
Imports System.EnterpriseServices
Imports System.Data.SqlClient
Imports System.IO
Imports System.Runtime.InteropServices

<ComVisible(True)> _
<Transaction(TransactionOption.RequiresNew)> _
Public Class VBServCom
    Inherits EnterpriseServices.ServicedComponent

    Public Sub New()


    End Sub

    <AutoComplete()> _
    Public Sub DoTxAuto()

        Dim sw As New StreamWriter("e:\temp\servicedcomponent.log")
        sw.WriteLine("VBServCom+DoTxAuto: {0}", Date.Now)
        sw.Close()

    End Sub

End Class


================================


========in assemblyInfo,vb===============

<Assembly: ComVisible(False)> 
<Assembly: ApplicationActivation(ActivationOption.Library)> 
<Assembly: ApplicationName("SimpleTrans")> 
<Assembly: Description("Simple Transactional application to show Enterprise 
Services")> 

============

also, I applied a strong-name to the assembly and installed it into GAC.

here is another web thread mentioend some potential problem which may be 
also helpful:

I believe COMVisible attribute is what I forgot!
I'll check on Monday!
Thanks!

RE: My Serviced component doesn't expose any methods!

Thanks for your reply Karre,

BTW, you can apply ComVisible attribute at both class level and assembly 
level, make sure you properly set both ones. You can refer to the examples 
I pasted previously.  Feel free to let me know if you've got it resolved.

RE: My Serviced component doesn't expose any methods!

I'm not sure if my previous post disappeared:
When using regsvcs I get a Warning:
"The assembly does not declare an ApplicationAccessControl Attribute.
Application security will be enabled by default.
No matter how I apply these settings I get the same warning.
?

RE: My Serviced component doesn't expose any methods!

Intriguing:
I backed down, tried to install your sample component in my COM+.
gacutil returns "Assembly successfully added to the cache." 
regsvcs returns "WARNING: The assembly does not declare an
ApplicationAccessControl Attribute. Application security will be enabled by 
default."

!!!
So, is it my environment?
Some setting from my VB6 COM+ component?
Or what?
?

RE: My Serviced component doesn't expose any methods!

Hi Kkarre,

I'm sorry to hear that it still not work. As for the warning you mentioned 
below:

==========
ns "WARNING: The assembly does not declare an
ApplicationAccessControl Attribute. Application security will be enabled by 
default."
=======

I also got this warning since this is a simple test assembly. I ignored 
this warning when testing.  You can add the following attribute in 
AssemblyInfo.vb file so as to eliminate the warning:

=================
<Assembly: ApplicationAccessControl(AccessChecksLevelOption.Application)> 
========================

Also, for gacutil, I haven't used it, but directly add/remove the 
strong-named dll via drag/drop in the c:\windows\assembly folder.  I've 
also tried using GacUtil.exe to add/remove the assembly and it also worked. 
 BTW, as you mentioned:

============
> So, is it my environment?
> Some setting from my VB6 COM+ component?
===========

i"m not sure whether there is anything involved VB6 here? So far my testing 
is through a Enterprised component assembly created via VB.NET class 
library project. For VB6 dll it can not be used via those .NET tools such 
as GACutil or regsvcs

If necessary, I can send you the test component I used on my side.

RE: My Serviced component doesn't expose any methods!

Hi Steven, thanks for your reply!
I did apply the <Assembly: 
ApplicationAccessControl(AccessChecksLevelOption.Application)> setting in my 
component
but somehow it didn't "stick". It seems to take a while, maybe today...
Your component installs fine in GAC today, d&d or gacutil equally works fine.
However when I add it to a COM+ application in Component Services there's
trouble: I get all interfaces, including the class interface _TestClass.
All interfaces show their methods EXCEPT the class interface.

Am I adding it the wrong way? I use 'Install New Component' and I browse to 
the
dll I used as original and drag'n'dropped it into GAC. The wizard won't let 
me select the one inside the GAC.

As for VB6, my project is migrating a VB6 COM+ installed component of 30+ 
dlls.
The code is now in VB2005 but I thought that the Upgrade Wizard might have 
brought a component setting or something from VB6 to VB2005.

I've tried calling the component anyway but gets error of kind
"couldn't create ActiveX component". This might be because the VB2005 dll
references three COM components still in VS6/C++ through COMInterop.
Perhaps it's impossible to use COMInterop inside COM+?
Wouldn't be logical - that's the perfect place for COM Interop; large 
enterprise apps
where you migrate step by step.

I'd be happy to try your code on my machine to rule out funny policies or 
something on my machine.
 
Thanks in advance!

RE: My Serviced component doesn't expose any methods!

One step closer:
I added ProgID attribute to your code and got my client to work!

RE: My Serviced component doesn't expose any methods!

Thanks for your reply Karre,

So the problem is at the Com+ registring stage. Why did you manually 
register it into COM+ applications?  As I mentioned in previous messages, 
in my test, I used the .NET framework regsvcs.exe tool to install the 
serviced component into COM+ applications.

#.NET Services Installation Tool (Regsvcs.exe)  
http://msdn2.microsoft.com/en-us/library/04za0hca(VS.80).aspx

The command is quite simple. For example, for my case the serviced 
component is named "SVCCOMLib.dll", I just run the following command in 
Visual Studio command prompt:

regsvcs.exe  SVCCOMLib.dll

and it will automatically do all the things without requiring me to do 
anything in the COM+ management console.

Sincerely,

Steven Cheng

RE: My Serviced component doesn't expose any methods!

I have used both regsvcs and the COM+ UI.
regsvcs returns a happy message but I can't see the COM+ application that 
has the installed component.
The people that will maintain this solution wanted to see the COM+ application
and components/interface/methods in it, so I tried that with COM+ Management 
console.
I'll try to read up on regsvcs to see how COM+ Management Console can show the
installed component!
Thanks!

RE: My Serviced component doesn't expose any methods!

Hi Karre,

Have you got any progress on this?
When you use regsvcs.exe to install the servicedcomponent into COM+ 
applications, it will create the COM+ application by the name you specified 
through 

<Assembly:ApplicationName("...." )> 

attribute(not the class name or assembly name), have you checked to see 
whether there is a COM+ application with this name? Also, are you using an 
administrator account when perform these tasks on the machine?

Sincerely,

Steven Cheng
