HRESULT DoDialog()
Microsoft Exchange calls the IExchExtAdvancedCriteria::DoDialog method when the user selects the Advanced button in the Find dialog box. The extension object should display a dialog box that enables the user to specify search criteria. The dialog box should be modal to the window specified in the hwnd parameter of IExchExtAdvancedCriteria::InstallAdvancedCriteria.
