Question

            appWord.ActiveWindow.View.Type = WdViewType.wdOutlineView;
            appWord.ActiveWindow.View.SeekView = WdSeekView.wdSeekCurrentPageFooter; 
            appWord.ActiveWindow.ActivePane.Selection.InsertAfter("打印日期：2010.5.28");
            appWord.Selection.ParagraphFormat.Alignment = Microsoft.Office.Interop.Word.WdParagraphAlignment.wdAlignParagraphCenter; // 设置右对齐
            appWord.ActiveWindow.View.SeekView = WdSeekView.wdSeekMainDocument;希望打印日期四个字是粗体的。这个怎么弄啊？
