delphi如何利用Excel97生成报表，十万火急！！！！！！（300大元奉上）(100分)

利用Excel97生成报表，最好可以给出例子。

可以调用OFFICE的宏来实现啊。调用OFFICE的宏能实现任何OFFICE功能（基本上）。
我这儿没有现成的怎么样来控制EXCEL的代码，虽然以前用过，可惜不在了。不过有怎么
样来控制WORD的代码，均测试通过的，其基本功能有书签定位、插入表格、替换字符等等
功能。我想原理是一样的，可以触类旁通嘛。
要不要，要的话，给你发一个过去。

我也要可以发一个吗？gyzly@263.net

实际上就是office vba,delphi5已经做了很多封装了

....
ExcelApplication1: TExcelApplication;
ExcelWorkbook1: TExcelWorkbook;
ExcelWorksheet1: TExcelWorksheet;
....

procedure Tfrmexcel.FormClose(Sender: TObject;
var Action: TCloseAction);
begin

Try
ExcelWorksheet1.Disconnect;
ExcelWorkbook1.Disconnect;
ExcelApplication1.Disconnect;
ExcelApplication1.Quit;
Except
on e:exceptiondo

showmessage(pchar('退出excel时出错,如果不能再次使用,请先结束任务:'+e.message);
end;

end;


procedure Tfrmexcel.createexcelform;
begin

try
ExcelApplication1.Connect;
ExcelApplication1.Visible[0]:=True;
ExcelWorkbook1.ConnectTo(ExcelApplication1.Workbooks.Add(EmptyParam,0));
// ExcelWorkSheet1.Activate;
ExcelWorkSheet1.ConnectTo(ExcelWorkbook1.WorkSheets.Add(EmptyParam,EmptyParam,EmptyParam,EmptyParam,0) as _WorkSheet);
ExcelWorkSheet1.Activate;
except
on e:exceptiondo

begin

showmessage(pchar('启动excel时出错,检查是否安装了excel:'+e.message));
ExcelWorksheet1.Disconnect;
ExcelWorkbook1.Disconnect;
ExcelApplication1.Disconnect;
ExcelApplication1.Quit;
exit;
end;

end;

end;

procedure Tfrmexcel.BitBtn2Click(Sender: TObject);
var i: integer;
begin

//创建excel
createexcelform;
//输出数据
Try
with datasetdo

begin

disablecontrols;
first;
while not eofdo

begin

for i:=0 to 域count-1do

begin

ExcelWorkSheet1.Cells.Item[RecNo,i+1] := Fields.AsVariant;
end;

next;
end;

enablecontrols;
end;

Except
on e:exceptiondo

begin

showmessage(pchar('输出数据时出错:'+e.message));
exit;
end;

end;

end;

还不行呀。我是要往一个已经做好的格式固定的excel表里面加数据。
现在有两个问题没法解决：
1。如何打开已经存在的excel表。
2。如何往表里添数据。

很简单，象上面的例子一样，先建立一个OLE Automation对象，然后用这个对象控制,你想
干什么都可以的。给你个例子，希望你看的懂：

if gb_ExcelHaveOpen = False then

begin

vExcel := CreateOleObject('Excel.Application');
sPath := ExtractFilePath(Application.ExeName);
sFile := sPath + CSTR_TRANVELPLACEMONTH;
vExcel.WorkBooks.Open(sFile);
vSheet := vExcel.WorkBooks[1].WorkSheets[1];
end;

with wwDBE_Monthen
tNo.DataSource.DataSetdo

begin

sYear := FieldByName('INFO_YEAR').AsString;
sEntNo := FieldByName('ENT_NO').AsString;
vSheet.Cells[5, 3] := FieldByName('ENT_NAME').AsString;
vSheet.Cells[6, 3] := FieldByName('ENT_NO').AsString;
.
.
.
end;

这方面的资料太多了。建议你最好把它做成一个控件。
通过控件到自动把数据库的数据写到Excel文件中。如果需要我这边有一堆资料。发给你

Excel也能当成数据库来操作。

Excel也能操作数据库。

jollier,用你的方法，我已经完整解决了问题。
其它朋友也提出了很好的办法。不过不太适合我的要求。在此也谢谢你们。

请热水发资料到zhao_jw@263.net 另外大家能否从使用模板定义的方式定义一个表
并从程序中得到数据入手，做出一个可用户定制的报表呢？希望大家讨论

可以发给我一份吗？急需多谢了。
