How to Scan & Fix ActiveX, OLE and COM error

COM

- Microsoft defines COM or Component Model as "a platform-independent, distributed, object-oriented system for creating binary software components that can interact. COM is the foundation technology for Microsoft's OLE (compound documents), ActiveX? (Internet-enabled components), as well as others". More details...

ActiveX

- An ActiveX control is essentially a simple OLE object that supports a variety of interfaces. More details...

OLE

- OLE (Object Linking and Embedding) is a standard developed by Microsoft. It allows you to create objects with one application and then link or embed them in a second application. Embedded objects retain their original format and links to the application that created them. In other words, OLE allows objects from one application to be embedded or linked within another (e.g., taking an Excel spreadsheet and putting it into a Word document). More details...

Scan & Fix ActiveX, OLE and COM error in Windows XP with Registry Cleaner software

Almost all Registry Cleaner software can Scan & Fix ActiveX, OLE and COM error, such as Registry Mechanic, Regcure Registry Optimizer, and Registry Booster. Following is the detailed guide on Registry Booster.

Registry Booster will search for currently installed COM and ActiveX objects. Registry Booster performs complete heuristic analysis of ActiveX, OLE, COM sections as they are interlinked and interdependent.

1. Run Registry Booster, Select "Registry Scan";

2. Select "Activex, OLE, COM sections";



3. Click "Start Scan".

COM

COM (Component Object Model) is a technique or an interface standard which objects and applications use to communicate. The standard is required since not all objects within your system 'know' each other's attributes, properties and capabilities. Therefore, an interface is required to allow standard ways of querying objects for respective functionality and subsequent execution of that functionality. Microsoft emphasises "COM specifies an object model and programming requirements that enable COM objects (also called COM components, or sometimes simply objects) to interact with other objects. These objects can be within a single process, in other processes, and can even be on remote machines. They can have been written in other languages, and they may be structurally quite dissimilar, which is why COM is referred to as a binary standard¡ªa standard that applies after a program has been translated to binary machine code...A COM object is one in which access to an object's data is achieved exclusively through one or more sets of related functions. These function sets are called interfaces, and the functions of an interface are called methods. Further, COM requires that the only way to gain access to the methods of an interface is through a pointer to the interface".

Therefore, COM is a software architecture or standard developed (by Microsoft) to build component- (or object-) based applications. COM objects have a unique identity, which expose interfaces thereby allowing applications and other components to access a variety of features. COM objects are more versatile than DLLs because they are entirely language-independent, have built-in inter-process communications capabilities, and fit easily into an object-oriented program design. COM was first released in 1993 with OLE2, largely to replace the interprocess communication mechanism DDE used by the initial release of OLE. ActiveX also is based on COM.

Put simply, COM is a technology that allows objects to interact across process and machine boundaries as easily as within a single process. COM enables this by specifying that the only way to manipulate the data associated with an object is through an interface on the object

ActiveX

An ActiveX control is essentially a simple OLE object that supports a variety of interfaces. ActiveX Controls have become the primary architecture for developing programmable software components for use in a variety of different containers, ranging from software development tools to end-user productivity tools. ActiveX controls register themselves in the Windows Registry.

OLE

OLE documents (also known as compound documents) seamlessly integrate various types of data, or pbjects. Sound clips and spreadsheets are good examples of components found in OLE documents. For example, if you are working on a Word document and create a linked to a number of cells in an Excel spreadsheet, the data for the linked item is stored in the original spreadsheet document. The Word document contains only the link to the original Excel spreadsheet. When you double-click the cells, Excel is launched and the original spreadsheet document is loaded from where it was stored.

OLE incorporates many other different concepts that all work toward the goal of seamless interaction between the applications installed on your computer. These areas include the following:

Linking and Embedding
Linking and embedding are the two methods for storing items created inside an OLE document that were created in another application as explained by the above examples.

In-Place Activation
Activating an embedded item in the context of the container document is called in-place activation. The container application's interface changes to incorporate the features of the component application that created the embedded item - if you double click on a linked Excel sheet within a Word document, you will notice how part of the user interface around the Excel document changes.
