2.4 About the example OLE/COM programs
2.4.1 OLE examples
The OLE examples are in the OLE folder under the Examples subfolder to your top-level Functional Developer installation folder:
- Bank
A three-tier example application that illustrates the use of custom (dual) interfaces to provide the intrastructure of a banking application.
- OCX-Scribble
An OLE control that implements a simple drawing application.
- OLE-Scribble
An OLE compound document server that implements a simple drawing application.
The applications in OCX-Scribble and OLE-Scribble are functionally the same except that one is built as a control and the other as a compound document server. (Thus they must support different COM interfaces in order to function as a control or server.)
- Button-OCX
An OLE control that uses a DUIM gadget to implement a simple button.
- Sample-DUIM-Container
An OLE container application, which uses a DUIM framework for the user interface, that can embed graphical objects from other programs.
The examples listed below demonstrate the use of low-level OLE interfaces to support creating and embedding graphical objects.
- Sample-OLE-Server
- An OLE compound document server application that can create COM objects that can be embedded in a compound document container application.
- Sample-OLE-Container
- An OLE compound document container application that can embed COM objects created by compound document server applications.
