ActiveX Objects
Movicon completely supports the new Microsoft ActiveX standard which allows response to events generated from objects which can be inserted in Movicon screens that have been created externally and not from within the system. This standard, known as ActiveX or OCX, allows you to enhance the operating possibilities of an Movicon application enormously, by letting the integration of any object created by third parties with any compiler or environment which supports this technology.
The ActiveX technology can be considered as an evolution of the OLE technology in the sense that an OLE object can be hosted, used and commanded by a container application which imparts orders and requests. An ActiveX object, however, in addition to this can take actions and generate events which the container application can respond to.
In general, the ActiveX objects are applications with .OCX extensions created by third parties based on Microsoft COM technology (Component Object Model).

Be able to dispose objects independently from applications, has its enormous advantages in terms of the re-usability of work carried out. In addition to this, there are companies who specialize in supplying specific objects as solutions to specific problems. This also adds a new element in the way of producing software. In the future it will be possible to get ready-made objects for inserting into personal applications, or sell parts of applications as ActiveX objects, independently from the language being used or from the type of application which the object is to be used by.
