OLE

These articles explain the fundamentals of OLE programming using MFC. MFC provides the easiest way to write programs that use OLE:

  • To use OLE visual editing (in-place activation).
  • To work as OLE containers or servers.
  • To implement drag-and-drop functionality.
  • To work with date and time data.
  • To manage the state data of MFC modules, including exported DLL function entry points, OLE/COM interface entry points, and window procedure entry points.

You can also use Automation or Remote Automation to operate another program from your program.

Note   The term OLE denotes the technologies associated with linking and embedding, including OLE containers, OLE servers, OLE items, in-place activation (or visual editing), trackers, drag and drop, and menu merging. The term Active applies to the Component Object Model (COM) and COM-based objects such as ActiveX controls. OLE Automation is now called Automation.
