delphi与excel的经典问题！困了我好长时间。希望大家帮忙？？ (50分)

在delphi中向excel导数，excelapp.open;导完以后excelapp.quit；但进程中的excel怎么也去不掉。
请大家帮忙。..
代码如下：
ExcelApp.Connect;//
ExcelApp.Visible[0]:=True;
// 打开已有的excel文件'e:/book1.xls'
excelworkbook1.ConnectTo(excelapp.Workbooks.Open('e:/book1.xls',NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
NULL,NULL,NULL,NULL,0));
excelworkSheet1.ConnectTo(excelworkBook1.Sheets['table1'] as _WorkSheet);
z:=wwtable1.RecordCount;
wwtable1.First;
excelworkSheet1.Cells.Item[1, 1] := 'A';
excelworkSheet1.Cells.Item[1, 2] := 'B';
for i:=2 to z do
begin
excelworkSheet1.Cells.Item[i, 1] := wwtable1.fieldbyname('A').asstring;
excelworkSheet1.Cells.Item[i, 2] := wwtable1.fieldbyname('B').asstring;
wwtable1.next;
next;
end;
///退出
try
// excelapp.Visible[0]:=true;
//excelapp.SaveWorkspace;
//excelapp.Save('e:/book1.xls');
excelApp.Disconnect;
excelworkbook1.disconnect;
excelworksheet1.disconnect;
excelApp.Quit;

正常不会出现这样的问题的。你的断开方式好象不太正确

>> excelApp.Disconnect;
>> excelworkbook1.disconnect;
>> excelworksheet1.disconnect;
>> excelApp.Quit;

应该
excelworksheet1.disconnect;
excelworkbook1.disconnect;
excelApp.Disconnect;
excelApp.Quit;

或直接EXCELAPP.QUIT也应该可以，你试试吧

excelApp.Quit;
excelApp:=nil;

接受答案了.
