Finally, we have successfully developed our COM component HelloComponent using C++. Let’s summarize how we developed our COM component in this article. Microsoft’s Component Object Model (COM) is a specification to allow to write of reusable components and enables them to communicate with each other. COM depends on interfaces to achieve its goals. One of […]
CoCreateInstance depends on IClassFactory to create class instances. We have looked into IClassFactory‘s methods and we have implemented these methods in our previous article. Let’s include IClassFactory‘s implementation into our HelloComponent. We already have HelloComponent‘s declaration in the “HelloComponent.h” file and its implementation in the “HelloComponent.cpp” file. In the same way, we will add the IClassFactory […]
In our previous article, we have identified that CoCreateFunction is requesting an instance of IClassFactory. Why CoCreateInstance is requesting an instance of IClassFactory? One of the goals of the COM is to locate the objects easily without worrying about where they are located and where they are housed; whether they are housed in in-process, local, or remote. in-process means, the […]
