Answer 2

为什麽只在第一次 能成功打开EXCEL，第二次就不行了
  excelapplication1.Connect;
  excelapplication1.Caption:='123';
  form1.ExcelApplication1.Visible[0]:=true;
  excelapplication1.Caption:='excel调用';
  form1.ExcelApplication1.Workbooks.Add(null,0);
  form1.ExcelWorkbook1.ConnectTo(excelapplication1.Workbooks[1]);
  form1.ExcelWorksheet1.ConnectTo(excelworkbook1.Worksheets[1] as _worksheet);
  form1.ExcelWorksheet1.Name:='第一页';
  form1.excelworksheet1.Activate ;

Answer 3

需要
ExcelWorksheet1.Disconnect;
ExcelWorkbook1.Disconnect;
ExcelApplication1.Disconnect;
都断开才行。

Answer 4

还是不行
form1.ExcelWorksheet1.Disconnect ;
  form1.ExcelWorkbook1.Disconnect ;
  form1.ExcelApplication1.Disconnect ;
  excelapplication1.Connect;
  excelapplication1.Caption:='123';
  form1.ExcelApplication1.Visible[0]:=true;
  excelapplication1.Caption:='excel调用';
  form1.ExcelApplication1.Workbooks.Add(null,0);
  form1.ExcelWorkbook1.ConnectTo(excelapplication1.Workbooks[1]);
  form1.ExcelWorksheet1.ConnectTo(excelworkbook1.Worksheets[1] as _worksheet);
  form1.ExcelWorksheet1.Name:='第一页';
  form1.excelworksheet1.Activate ;

Answer 5

excelapplication1.Quit;
excelapplication1.Disconnect;
这两句断开连接。也可以直接关闭EXCEL。
用WOM、超级兔子等查看进程，如有EXCEL则KILL。
最简单方法，CTRL+ALT+DEL，查看正在运行的程序，
如有EXCEL则KILL。

Answer 6

excelapplication1.Quit;
excelapplication1.Disconnect;
这两句也加上去了，怎样才能直接关闭EXCEL程序呢，我不能每次调用完后都按CTRL+ALT+DEL来关闭EXCEL啊

Answer 7

可以了，将CONNECTKIND改一下就可以了，糊弄了大家半天不好意思。

Answer 8

还是不行啊，进程中有太多的EXCEL程序在运行，都没有被关闭，这样很容易死机。
怎样彻底关闭EXCEL程序

Answer 9

难道就不能用ADO 操作EXCEL吗？
