Using the OLE/COM Object Viewer

You can use the OLE/COM Object Viewer to view a control's interfaces.

To use the OLE/COM Object Viewer

  1. Start the OLE/COM Object Viewer (oleview.exe), which is located in the \Program Files (x86)\Windows Kits\8.0\bin\x86\ folder.

  2. In the Object Classes, Grouped by Component category in the viewer, open the Automation Objects folder to view the registered Automation objects.

  3. Select one of the controls. Several tabs appear in the right pane; the interfaces that are implemented by the control are displayed on the Registry tab.

    • If you open the shortcut menu for a control in the left pane and then choose View Type Information, the ITypeInfo Viewer displays a reconstructed .idl or .odl file.

    • If you expand the control node in the left pane, a list of the interfaces in the object is displayed. If you select an interface, its registry entry is displayed in the right pane.

    • If you open the shortcut menu for an interface and then choose View, the OLE/COM Object Viewer displays a dialog box that shows the GUID for the interface and an option to view type library information, if it is available. Selecting View Type Info displays a portion of a reconstructed .idl file that is specific to the interface in the ITypeInfo Viewer.

    • In the ITypeInfo Viewer, you can select an interface member in the tree view to display the accessor method signatures in the right pane.
