Description

The generic function report-active-component-failure is used to report on failures to find or create a component.

component-name is the name of the component it tried to find.

error-string is the error string.

function-name is the name of the function that actually failed.

hresult is the hresult that came back. It may be nil if the error is that the guid of the named component could not be found.

When the system fails to open the component, it calls report-active-component-failure, with the first argument the ole-control-pane pane . The default method for ole-control-pane tries to call report-active-component-failure again on its top level interface. The default method on interface calls error.

You can add your own methods, specializing on subclasses of ole-control-pane or subclasses of interface.
