COM was created to replace DDE since its text-based conversation and Windows messaging design was not flexible enough to allow sharing application features in a robust and extensible way. In 1994, the OLE custom control (OCX) technology, based on COM, was introduced as the successor to VBX. At the same time, Microsoft stated that OLE 2 would be ...
ActiveX is a deprecated software framework created by Microsoft that adapts its earlier Component Object Model (COM) and Object Linking and Embedding (OLE) technologies for content downloaded from a network, particularly from the World Wide Web. [1] Microsoft introduced ActiveX in 1996.
OLE 1.0 later evolved to become an architecture for software components known as the Component Object Model (COM), and later DCOM. When an OLE object is placed on the clipboard or embedded in a document, both a visual representation in native Windows formats (such as a bitmap or metafile) is stored, as well as the underlying data in its own ...
Solving the dependencies for one software may break the compatibility of another in a similar fashion to whack-a-mole. If app1 depends on libfoo 1.2 , and app2 depends on libfoo 2.0 , and different versions of libfoo cannot be simultaneously installed, then app1 and app2 cannot simultaneously be used (or installed, if the installer checks ...

Distributed Component Object Model (DCOM) is a proprietary Microsoft technology for communication between software components on networked computers. DCOM, which originally was called "Network OLE ", extends Microsoft's COM , and provides the communication substrate under Microsoft's COM+ application server infrastructure.
With interface injection, dependencies are completely ignorant of their clients, yet still send and receive references to new clients. In this way, the dependencies become injectors. The key is that the injecting method is provided through an interface. An assembler is still needed to introduce the client and its dependencies.
Dependencies and transitive dependencies can be resolved at different times, depending on how the computer program is assembled and/or executed: e.g. a compiler can have a link phase where the dependencies are resolved. Sometimes the build system even allows management of the transitive dependencies. [citation needed]
