Is there a way to tell gcc that the abstract class it's compiling does not need a virtual destructor (like COM-objects never have)? For example nsISupports always complains about the missing virtual destructor. Turning off the warning would not help as I may have non-COM-like classes, where I want this warning. So __attribute__((com_int...

I have a number of COM services in my system and I need to change default cloaking beahvior. In particular, I want to use dynamic cloaking. Since the product is a "closed" one, meaning that no other program/service will be installed on the machine, changing system defaults is one of the options. I am not willing to go into that directio...

I have been told to develop a virtual com port so an app the company has can read off com "comCompanyNameV1".. I tried to pick apart com0com, but it seem so incomplete I'm finding I have to kludge around large parts of it and I have yet to get anything to come close to compiling. Mostly because the tools that are outlined to use to build...

I've already written the functionality I need in C++: Basically, I have a manager class that use...
Is it possible to configure a REST (WCF) service to run as STA instead of MTA? This is approach is needed in order to run legacy COM objects. In order to configure ASMX web services to run as STA instead of MTA, there is a workaround available that uses an HTTPHandler to force the web service to run as STA. An article by Jeff Prosise ...

Hi, Consider me a novice to windows environment and COM programming. I have to automate an application (CANoe) access. CANoe exposes itself as a COM server and provides CANoe.h , CANoe_i.c and CANoe.tlb files. Can anyone specify how to write a C++ client, for accessing the object, functions of the application.

Our system looks like this: One or many applications containing one or many in-process COM component(s), that communicate with some hardware via a single COM server. (Hope that makes sense - please ask if it needs clarification) The design decisions that led to this system design have been lost in the mists of time, however I think tha...
I need to use a COM component (a dll) developed in Delphi ages ago. The problem is: the dll does not contain a type library... and every interop feature (eg. TlbImp) in .NET seem to rely on TLBs. The component has been used in Delphi programs here for many years without problems because "It's not much of a problem using COM objects from ...

I am building a C# UI to interact with a COM Service (.exe). The VS2005 COM project outputs a valid typelib (TLB), which is referenced by the C# project. However, the VS2005 C# project insists that the service be registered in order to build the C# project, even though the typelib appears perfectly valid when examined with the OLE Obje...
Say you do the following: 1) Load foo.dll using LoadLibrary. 2) Get a pointer to a function using GetProcAddress. 3) Invoke the function, giving you a reference to a COM object implememented in that module. 4) Free foo.dll by calling FreeLibrary. 5) Call a method on the COM object. Would you expect that step 5 succeeds and doesn't ...
Hi all, currently I'm struggling trying to use a COM dll on a simple system that I've made. Everything compiles successfully, but in runtime the CoCreateInstace is returning S_OK, but somehow my object pointer is returning NULL. This interface pointer is created on my class header. The weirdest thing is that instantiating this same po...
