如何使用Office相关的那些控件

Question

首先可以参考delphi自带的demo，在activex/oleauto/word8目录

Answer 1

我给你一个使用Excel的例子
先将在Form中添加
    ExcelApplication1: TExcelApplication;
    ExcelWorkbook1: TExcelWorkbook;
    ExcelWorksheet1: TExcelWorksheet;
使用Excel
Try
        ExcelApplication1.Connect();
      Except
      End;
      ExcelApplication1.Visible[0]:=True;
      //增加一个Workbook
      ExcelWorkbook1.ConnectTo(ExcelApplication1.Workbooks.Add(EmptyParam,0));
      Temp_Worksheet:=ExcelWorkbook1.Worksheets[1] as _WorkSheet;
      ExcelWorksheet1.ConnectTo(Temp_Worksheet);
      ExcelWorksheet1.Cells.Item[1,1]:='营业部简称';
      ExcelWorksheet1.Cells.Item[1,2]:='交易日期';
Except
        ShowMessage('Excel非法退出！！');
        Exit;
      end;
另外在ExcelApplication的WindowDeactivate事件中添加以下代码
procedure ExcelApplication1WindowDeactivate(Sender: TObject;
  var Wb, Wn: OleVariant);
begin
  inherited;
  Try
    ExcelApplication1.Quit;
    ExcelWorksheet1.Disconnect;
    ExcelWorkbook1.Disconnect;
    ExcelApplication1.Disconnect;
  Except
  End;
end;

Answer 2

补充上面
var
  Temp_Worksheet: _WorkSheet;
