Accessing OLE Automation Objects

To access exposed objects, you can create OLE Automation controllers using Microsoft Visual Basic™, Microsoft Visual C++™, Microsoft Excel, Microsoft Project, and other applications and programming languages that support OLE. This chapter discusses several strategies for accessing exposed objects:

  • Creating scripts with Microsoft Visual Basic

  • Creating your own controllers that manipulate objects

  • Creating type information browsers

Regardless of the strategy you choose, your OLE Automation controller needs to follow these steps:

To initialize and create the object

  1. Initialize OLE.

  2. Create an instance of the exposed object.

To manipulate methods and properties

  1. Get information about the object's methods and properties.

  2. Invoke the methods and properties.

To release OLE when your application or programming tool terminates

  1. Revoke the active object.

  2. Unitialize OLE.
