You have to re-import the ActiveX. Otherwise the classwizard generated wrapper class for your interface won't contain the new interface function.
By registering the component you simply add information to the registry, e.g. where the typelib for the component can be found. The registration procedure does not magically change any code in your client.
Of course you can "manually" add the new interface function to your client's interface wrapper class without re-importing the component. Have a look at how "funl" is handled and you should be able to figure it out. Just be careful to get the dispid and the argument list correct.
Hope this helps

Hi Roger,
I'm not importing ocx, as you mentioned.
I'm using Coledispatchdriver class instead. By some efforts, I found that, the problem occurs on m/c , having this activex installed previously(old version, without new function). In that case, after registration, new value named InprocServer32 (its not key), is stored under key InprocServer32. Which contains some garbage.
If I delete that value, it works fine  .
Still cant figure out problem.
thanks for your concern.

Sorry Prasad, I cannot figure that one out. At least not right now.
But I must say I don't really get your problem... 
1. You have an older version of the ActiveX without the new function that works fine.
2. When you register the newer version it adds the InprocServer32 value below the InprocServer32 key and fills it with "garbage".
3. If you delete the InprocServer32 value, the new version works fine.
Is this correctly understood?
What happens if you unregister the previous version before registering the new?
Is the "garbage" a MULTI_SZ similar to the same value for the "Microsoft ProgressBar Control, version 6.0" (CLSID = {35053A22-8589-11D1-B16A-00C0F0283628})?
What happens if you change the contents of the InprocServer32 value instead of deleting it? Error messages when trying to create the server?

No success.

yes, its similar to it.

Haven't tried it. But , as mentioned earlier, deleting it was the solution( obviosly, cant ask user to do that  , i.e. to play registry).
I tried to access added function from activex control test container. I can see it in list. But again show no effect on pressing invoke. Same thing happen when tried to access new function in vb code. Intellisense shows added function. But in run , error comes, telling 'object doesn't support this property/method'.
thanks.

The InprocServer32 key's default value is always the path to the library containing the server, but I haven't seen the value with the same name before.
So: I've google'd around trying to get some information about this mysterious InprocServer32 value.
It turns out that the most usual usage of this value is by installing the server with InstallShield and provides some kind of support for update service.
I have to dig deeper to get more out of it, but perhaps I don't have to...
Now to the obvious question: are you at some point using and/or registering InstallShield, or any external installer...? Or am I barking up the wrong tree?

No I'm just using regsvr32 commandline.

I found this[^] KB article at InstallShield's site.
It seems like it is the "Microsoft Windows Installer Service" that uses this registry value on "recent" platforms, i.e. w2k and later.
Since you're simply registering the server through command line, I suspect you're building the server with a MSVC version greater than 6.0 and the registration of this value is burried somewhere in the framework. Usually I'm working with MSVC6 so I'm not that familiar with later versions.
If you put a breakpoint inside the server's DllRegisterServer you should get to the code that registers this value...eventually.
Doesn't sound like much fun though. I think it would make sense if you could disable this feature somewhere in the call chain of DllRegisterServer.
BTW, are you able to call any other interface function of your server successfully?

I have been trying to expose an ATL or class objects from an ActiveX control I have created using VC6 MFC.
Any Genius out there who have experience with this?
What I want is to have an ActiveX control "ControlX" what have a property "PropertyY" that is actually a class/ATL with methods and properties.
So If I am using VB6 to call a method in "PropertyY":
call ControlX.PropertyY.MethodZ
Any suggestions are welcome!

You can use #import to get wrapper classes for the stuff implemented, providing that the DLL has a typelibrary embedded in it.

Thanx Steve
Did u mean i should call getprocaddress on all functions i needed from that dll and make a wrapper around those functions...

You need to use #import "yourdll.dll" statement in your code. Doing so, .tlh, and .tli will be generated in debug/release folder. You can use .tlh as header.

Thanx prasad
I have used #import "mydll.dll" in my code but it giving error as
"fatal error C1083: Cannot open type library file: 'mydll.dll': Error loading type library/DLL"
Any alternative do you want to suggest,i think type library is not embeded in this dll...

You need to give, full path, mentioning "\\".

Hello,
In my VC++.NET 2003 multithreaded application I need to use some COM server. I can call it from both threads using RCW, but after some period of time I have this error message: “COM object that has been separated from the underlying RCW can not be used” from the main thread. I don’t use Marshal::Release(…) explicitly, it means garbage collector decided to free some memory and destroyed my object. I already tried to increase reference count using Marshal::AddRef(…) and I tried to create additional global instance of this object. Both approaches didn’t work. How to tell Framework not to destroy this object? Please help!
Regards,
Leonid

Hi
I am using COM object in Web Application. There is a problem to solve authentication & authorization issue for Server site. At the time of using the COM object it shows the error " ACCESS DENIED ". If I am writing <identity impersonate="true"> in web.config, it is OK but the AJAX file is not accessible for that reason.
if I am using iisreset in Run command, then the whole application is OK, but it is not possible to reset iis again and again in production server. Have you any idea for this?
For more clarification, suppose there is a link in a Web page interface. After click the link, one Word document will open. How we solve authentication/authorization issue in iis without affecting to other files like AJAX.
I am using ASP.NET with C#. I am not using MTS.
any idea, please write.
regards

Hi
I am using static binding i.e the use of dll of MS OUTLOOK 2003 in my Windows application to extract FROM,TO,CC,BCC,MESSAGE email addresses and their names etc. and store it into an MS ACCESS database. The module is working fine in my machine and also in client machines, but some of the clients are complaining that they are getting the error at the time of running the module. They are also using MS Office Outlook 2003. They are getting the error when try to run the application.
The error is like this:
System.IO.FileNotFoundException: The specified module could not be found.
I think sometimes CLR fails to load unmanaged dll of OUTLOOK. I have tried by using most of things but till now there is no success. All the dlls are present in applications root folder.
Is there any idea?
regards

Hello,
I write an ActiveX control that automates MS Word. Specifically, the control embeds MS Word into a PowerPoint presentation. The problem that I faced is a thin border around the control when the presentation is run. I need to get rid of it so that there are no any borders around the control. I have tried to resize the control by calling the main frame's MoveWindow hoping the border will move out of the visible area, but the border still persists. Apparently, the border has nothing to do with the main frame. So the question is - how to get rid of this border?
Thanks in advance.
Dennis.
