Called before IFileDialogEvents::OnFolderChange. This allows the implementer to stop navigation to a particular location.
Type: IFileDialog*
A pointer to the interface that represents the dialog.
Type: IShellItem*
A pointer to an interface that represents the folder to which the dialog is about to navigate.
Type: HRESULT
Returns S_OK if successful, or an error value otherwise. A return value of S_OK or E_NOTIMPL indicates that the folder change can proceed.
The calling application can call IFileDialog::SetFolder during this callback to redirect navigation to an alternate folder. The actual navigation does not occur until IFileDialogEvents::OnFolderChanging has returned.
If the calling application simply prevents navigation to a particular folder, UI should be displayed with an explanation of the restriction. To obtain a parent HWND for the UI, obtain the IOleWindow interface through IFileDialog and call IOleWindow::GetWindow.
