dotnet distributed apps : My Serviced component doesn't expose any methods!
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.
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: #ServicedComponent RegistrationException - Invalid Derived Classes http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=138251&SiteID=1 Sincerely, Steven Cheng Microsoft MSDN Online Support Lead Delighting our customers is our #1 priority.

I believe COMVisible attribute is what I forgot!
I'll check on Monday! Thanks! [quoted text, click to view] "Steven Cheng [MSFT]" wrote:

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. Sincerely, Steven Cheng Microsoft MSDN Online Support Lead Delighting our customers is our #1 priority.

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. ? /kk [quoted text, click to view] "Steven Cheng [MSFT]" wrote:

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? ? /kk [quoted text, click to view] "Steven Cheng [MSFT]" wrote:

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! /kk [quoted text, click to view] "Steven Cheng [MSFT]" wrote:

One step closer:
I added ProgID attribute to your code and got my client to work! [quoted text, click to view] "Steven Cheng [MSFT]" wrote:

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! [quoted text, click to view] "Steven Cheng [MSFT]" wrote:

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: ============ [quoted text, click to view] > 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.

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.

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 Microsoft MSDN Online Support Lead Delighting our customers is our #1 priority.
