You are developing remote server applications, when you need to unregister. Early binding is the most efficient method of accessing an ActiveX component. The Dim statement, the Friend statement, the GetObject function, the Private. Exposing a VB5 app to GetObject I have an ActiveX EXE application written in VB5. I want to allow other applications to get a reference to it while it is running by calling GetObject('MyApp').

Hi The VB6 help on GetObject says 'You can't use GetObject to obtain a reference to a class created with.' My VB6 GUI exposes objects as an ActiveX exe, for other components to manipulate.

I want the other components to connect to the GUI that's already running, rather than start a new instance of the exe. I've found using GetObject does work, if you use GetObject(', 'ProjectName.ClassName').

It worries me that the help says this shouldn't work, although I have done quite a bit of testing and haven't found any problems so far. Any COM experts out there who can tell me whether I going to run into problems down the line?

Then the help is obviously wrong (but don't know the context in which that was stated). Maybe they meant - you cannot use GetObject against Private Classes in a given Project - and it also will not work against Public Classes which are hosted in an AX-Dll (these require CoCreateInstance or CreateObject). GetObject always expects an already *running* instance of a COM-Class, hosted in a Process, which is capable regarding (cross-process) OLE-Marshaling.

And a VB-ActiveX-Exe is such a 'marshaling-capable' hosting instance (process). Another such instance (more a sheduler) is for example the Running-Objects-Table. The ROT, which is visible system-wide and could also offer classes for OLE- marshaled access, reachable per GetObject then, when you register a 'normal Public Class' (which could also be defined in an AX-Dll) from a running Std- VB-Exe-Process. > My VB6 GUI exposes objects as an ActiveX exe, for > other components to manipulate.

That should work fine, as long as your hosting-process which offers these Object-interfaces for marshaling, always 'is there' for the other (satellite-)processes - be it in case of 'connecting' (per GetObject) - or in case of 'accessing and using the marshaled methods' from a client-processes point of view as long as the client (and the marshaled clientside object-ref) lives.

In case of a clientside connect-call you will get a nice Error-message (in case your AX-Exe-Server is not yet running) - more problematic to handle is the case, should the Server-Process go out of scope, in case the client-processes already got a marshaled ObjPtr to work against (the clientside Object- or Class-Variable). Method-Calls on such an Object-Variable (which are marshaled under the hood) always need special attention and error-handling in your client-apps. But that's a common problem, which is there in each cross-process COM-access scenario - it has nothing to do with GetObject (which is only the connect-call).

After a successful GetObject you got your marshaled (remote-) COM-ObjectVariable at hand in your App - you can then forget about GetObject - what now applies, are the rules, how to work with 'COM-Remote- Objects' (as for example is exactly the same as when you work against a 'remote-sheet' of an Excel-Instance).

Another point that might be worth exploring: According to the MSDN page your method will create a new instance. Dino Esposito says the same thing in his book. (I'm assuming the function works the same way in VBS as in VB, but I'm not certain.) He says that this always returns a new object: GetObject(', 'Server.Class') while this will return a running instance, or an error if there is no running instance: GetObject(, 'Server.Class') Further, he says that which instance you get is undefined but that in his own tests he always got the oldest instance. On the original issue, I don't know for sure, but I'm guessing they meant that you can't reference a class internally.

If the statement is taken literally then it implies that there are different kinds of publicly creatable COM objects.
