OLEVIEW: ActiveX Object Viewer

  • Article

The OLEVIEW sample illustrates how to implement ActiveX™ Object viewers through custom ActiveX interfaces. These custom interfaces are implemented in Iviewers.dll.

This sample includes two projects that you need to build: Iviewers.mak and Oleview.mak. To run OLEVIEW, make sure that Iviewers.dll is in the same directory as Oleview.exe or in a directory in your path.

The application has an SDI interface with two panes. The left pane allows you to browse the registry by means of a tree control. Once you select a node, the right pane will display the pertinent information.

If you select a type library in the tree control and double-click it, the type library viewer will be called.

This sample demonstrates the following keywords:
