CA Gen as an OLE Automation Controller

An OLE automation controller is an application that accesses and controls OLE automation objects.

CA Gen can be an automation controller. For example, OLE automation allows you to remotely operate OLE server applications such as Microsoft Word or Excel. The following illustration shows this role.

In the illustration, communication is from the CA Gen application to the desktop application (for example, an Excel spreadsheet). CA Gen acts as an OLE automation controller. CA Gen initiates the communication. The desktop application is presented in its own window in the CA Gen application.

The other OLE application can have the following characteristics:

• Be completely external, including all of its presentation.
• Have its presentation embedded in the window of the CA Gen application. For more information, see CA Gen Control through Embedding.
