With OLE, editing applications are able to export portions of documents to one another. For example, a photo editing application could export portions of text to a word processor, spreadsheet program or database application using OLE. The primary function and benefit of OLE is its ability to enable users to be able to export data from one kind of application to another kind of application, such as an image editor to a word processor. Through this process you have what is called a master file, which reflects the changes made to it from whichever program.

The primary responsibility of OLE is to manage these compound document types, but it can also be used for a variety of other tasks, such as dragging and dropping data amongst different applications.

Embedding, which is essentially what OLE is used for, is the central component of multimedia in web pages, because it enables you to merge animation, video and audio files to your HTML pages. Today’s internet browsers use a variety of embedding mechanisms, with OLE being amongst the most popular.

What Is An OCX?

Before you can understand OCX (ActiveX Control / OLE Control Extension), having some understanding of OLE is a must, which is why I ventured into it briefly above, all computers use a variety of software types that have their own unique functionality and characteristics. Tasks are completed when each of these applications are able to work together as a unit. There are situations when a user attempts to complete a specific task, which is beyond the capabilities of the specific application they are attempting to complete the task on. Because the application lacks the attributes that would otherwise enable it to complete the task, as a substitute it will call upon another application that does have the appropriate feature set to enable it to complete its task. As was explained above, the OLE is what makes this possible. OCX on the other hand is an updated version of OLE, with more advanced features, enabling developers to be to create an array of additional customisations.

You see working examples of OCX every day on the internet. Basically, whenever you visit a specific web page that fuses interactivity and dynamism to get its point across, in most cases, OCX is what is used to embed the various types of content onto the page.

If I were to delve deeper, this could get rather complicated, so I’m going to summary things for simplicity sake. The OCX is basically a more advanced version of OLE which gives certain applications their multifaceted nature, such as an internet browser.

OCX conflicts are not so common, but with anything computer related, there are times when things can and do break down. If you’re currently bogged down with OCX / ActiveX errors, (which is more than likely, if you’re here), then continue reading, to learn a variety of methods that you can use to verifiably fix this issue.
