Security noteSecurity Note

This sample code is provided to illustrate a concept and should not be used in applications or Web sites, as it may not illustrate the safest coding practices. Microsoft assumes no liability for incidental or consequential damages should the sample code be used for purposes other than as intended.

Building and Running the Sample

To build and run the OLEVIEW sample

  1. Open the solution oleview.sln.

  2. On the Build menu, click Build.

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.

Note that this sample application cannot display information for all the objects, but rather only for objects that support the IViewer interface.
