An ActiveX control is a reusable part of data and code made utilizing ActiveX technology. It enables you to make segments that can be utilized as a part of any task straight away. This saves a considerable amount of development time. ActiveX speaks about binary interoperability. That implies just compiled parts are reusable and not source code.

  Here are the following properties defined by ActiveX controls.

  1. Stock: These are fundamental properties provided for each control, for example, font or color. The developer must enact stock properties. However, there is little, or no coding included.
  2. Extended: These properties are handled by the compartment, usually including placement and size on screen.

The IUnknown interface gives customers a chance to get pointers to different interfaces on a given object through the Query Interface strategy, and deal with the presence of the object through the IUnknown AddRef and IUnknown Release methods. IUnknown techniques can be utilized to switch between interfaces on an object, including references, and release objects.
ACTIVEX DLL: An in-process part, or ActiveX DLL, keeps running in another application’s procedure. Applications or other in-process segments utilize In-process parts. This enables you to wrap up basic functionality (like an ActiveX Exe).

ACTIVEX EXE:  An out-of-process segment, or ActiveX EXE, keeps running in its specified address space. The customer is usually an application running in another process. The code running in an ActiveX Exe is running.
