Notifies the handler to display its UI.

Syntax

HRESULT ShowProperties(
  [in] HWND hwnd
);

Parameters

Return value

Type: HRESULT

This method can return one of these values.

Return code Description
S_OK
 The user changed one or more settings.
S_FALSE
 No settings were changed.

Remarks

A handler can display a UI, which is typically used to allow the user to select which files are to be cleaned up and how. To do so, the handler sets the EVCF_HASSETTINGS flag in the pdwFlags parameter when Initialize is called. The disk cleanup manager will then display a Settings button. When that button is clicked, the disk cleanup manager calls ShowProperties to notify the handler to display its UI.
