How to obtain the resource manager (floder explorer), click the folder/file event

CodePudding user response:

Resource manager own implementation IShellBrowser don't need you to write a,

Resource manager for the implementation of the IWebBrowser2 is to give the Document property returns the current ShellFolderView, DWebBrowserEvents2: such as: NavigateComplete2 event triggers, hanging on to the current value of the Document DShellFolderViewEvents: : the SelectionChanged went, of course BeforeNavigate2 and exit to cancel to this event listener can have leak, otherwise

From the resource manager IShellWindows IWebBrowser2 methods refer to https://devblogs.microsoft.com/oldnewthing/20040720-00/? P=38393. Then I can hang DWebBrowserEvents2,

Since using ATL, need not taught how to hang events,
