jacob操作outlook
大家好,我想知道为explorer 里 除了outlook Selection(当前选中)还有哪些选项,比如所有的,比如未读的,已读的，删除的。草稿箱。 这些参数要怎么写，我怎么知道它里面有哪些参数？ 跪求！ 我很奇怪既然是固定参数为什么不定义一个常量类。

 ActiveXComponent xl = new ActiveXComponent("Outlook.Application");  

    	  

         Dispatch explorer = Dispatch.get(xl,"ActiveExplorer").toDispatch();  

         Dispatch selection = Dispatch.get(explorer, "Selection").toDispatch();  

         Variant count = Dispatch.get(selection, "Count");  

   

         for (int mailIndex = 1; mailIndex <= count.toInt(); mailIndex++ ) {  

             Dispatch mailItem = Dispatch.call(selection, "Item", new Variant(mailIndex)).toDispatch();  

   

             Variant senderName = Dispatch.get(mailItem, "SenderName");  

             Variant subject = Dispatch.get(mailItem, "Subject");  

             Variant body = Dispatch.get(mailItem, "HTMLBody");  

       

             String emailFileName = subject.toString() +".txt";    

               

             try {  

                 File email = new File(emailFileName);  

                 PrintWriter writer = new PrintWriter( new FileWriter(email) );  

                 writer.println("From: "+ senderName );  

                 writer.println("Subject: "+ subject);  

                 writer.println("");  

                 writer.print( body );  

                 writer.close();  

             }  

             catch (IOException e) {  

                 System.out.println("IOException writing e-mail with subject: '"+ subject +"'");
