EXCEL的例子:var aSheet:Variant; i:integer;begin //显示Ms-excel的执行过程 ExcelApplication1.Visible[0]:=True; ExcelApplication1.WorkBooks.Add(xlWBATWorksheet,1); aSheet:=ExcelApplication1.Worksheets.Item[1]; aSheet.cells[1,1].Value:='会员卡号'; aSheet.cells[1,2].Value:='会员姓名'; aSheet.cells[1,3].Value:='累计消费金额'; aSheet.cells[1,4].Value:='职业'; aSheet.cells[1,5].Value:='会员级别'; aSheet.cells[1,6].Value:='专卖店名称'; //asheet.cells[20,1].Value:='总计'; i:=2; with adoquerytotal do begin first; while not eof do begin aSheet.cells[i,1].Value:=FieldbyName('hykh').Asstring; aSheet.cells[i,2].Value:=FieldbyName('name').Asstring; aSheet.cells[i,3].Value:=FieldbyName('column1').Asstring; aSheet.cells[i,4].Value:=FieldbyName('job').Asstring; aSheet.cells[i,5].Value:=FieldbyName('hyjb').Asstring; aSheet.cells[i,6].value:=FieldbyName('zmdname').AsBoolean; i:=i+1; next; //aSheet.SaveAs('d:\qqq.xls'); // OleContainer1.CreateobjectFromFile('d:\qqq.xls',false); // aSheet.Application1.quit; end; end;
给你一个转EXCEL的例: procedure Tfrmtoexcel.BitBtn1Click(Sender: TObject); var i,j:integer; f:TextFile; sl:TStringList; begin with dm.tbtoexcel do begin if (not dm.tbtoexcel.Active) then Exit; if (not SaveDialog1.Execute) then Exit; AssignFile(f,SaveDialog1.FileName); try Rewrite(f); except Showmessage('保存文件失敗!'); CloseFile(f); Exit; end; Screen.Cursor := crHourGlass; DisableControls; sl := TStringList.Create; sl.Clear; for i:=0 to FieldCount-1 do begin if (Fields[i].Visible) then sl.Add(Fields[i].DisplayLabel); end; writeln(f,sl.CommaText); First; for j:=0 to RecordCount-1 do begin sl.Clear; for i:=0 to FieldCount-1 do begin if (Fields[i].Visible) then sl.Add(VarToStr(Fields[i].Value)); end; writeln(f,sl.CommaText); Next; end; sl.Free; CloseFile(f); EnableControls; Screen.Cursor := crDefault; end; // withend; 我还尝试过用BCP, 也是可行的,不过需SQL SERVER后台数据库.
5) 添加新工作表: var Temp_Worksheet: _WorkSheet; begin Temp_Worksheet:=ExcelWorkbook1. WorkSheets.Add(EmptyParam,EmptyParam,EmptyParam,EmptyParam,0) as _WorkSheet; ExcelWorkSheet1.ConnectTo(Temp_WorkSheet); End;
aSheet:Variant;

//显示Ms-excel的执行过程
ExcelApplication1.Visible[0]:=True;
ExcelApplication1.WorkBooks.Add(xlWBATWorksheet,1);
aSheet:=ExcelApplication1.Worksheets.Item[1];
aSheet.cells[1,1].Value:='会员卡号';
aSheet.cells[1,2].Value:='会员姓名';
aSheet.cells[1,3].Value:='累计消费金额';
aSheet.cells[1,4].Value:='职业';
aSheet.cells[1,5].Value:='会员级别';
aSheet.cells[1,6].Value:='专卖店名称';
//asheet.cells[20,1].Value:='总计';
i:=2;
with adoquerytotal do
begin first; while not eof do begin

aSheet.cells[i,5].Value:=FieldbyName('hyjb').Asstring;
aSheet.cells[i,6].value:=FieldbyName('zmdname').AsBoolean;
i:=i+1; next;
//aSheet.SaveAs('d:\qqq.xls');
// OleContainer1.CreateobjectFromFile('d:\qqq.xls',false);
// aSheet.Application1.quit; end;
end;
procedure Tfrmtoexcel.BitBtn1Click(Sender: TObject);
var
i,j:integer;
f:TextFile;
sl:TStringList;

if (not dm.tbtoexcel.Active) then

try

except

CloseFile(f);

end; Screen.Cursor := crHourGlass;
DisableControls;
sl := TStringList.Create;
sl.Clear;
for i:=0 to FieldCount-1 do
begin
if (Fields[i].Visible) then

end; // withend;
我还尝试过用BCP, 也是可行的,不过需SQL SERVER后台数据库.
一) 使用动态创建的方法首先创建 Excel 对象,使用ComObj:
var ExcelApp: Variant;
ExcelApp := CreateOleObject( 'Excel.Application' );1) 显示当前窗口:
ExcelApp.Visible := True;2) 更改 Excel 标题栏:
ExcelApp.Caption := '应用程序调用 Microsoft Excel';3) 添加新工作簿:
ExcelApp.WorkBooks.Add;4) 打开已存在的工作簿:
ExcelApp.WorkBooks.Open( 'C:\Excel\Demo.xls' );5) 设置第2个工作表为活动工作表:
ExcelApp.WorkSheets[2].Activate;
或
ExcelApp.WorksSheets[ 'Sheet2' ].Activate;6) 给单元格赋值:
ExcelApp.Cells[1,4].Value := '第一行第四列';7) 设置指定列的宽度(单位:字符个数),以第一列为例:
ExcelApp.ActiveSheet.Columns[1].ColumnsWidth := 5;8) 设置指定行的高度(单位:磅)(1磅=0.035厘米),以第二行为例:
ExcelApp.ActiveSheet.Rows[2].RowHeight := 1/0.035; // 1厘米9) 在第8行之前插入分页符:
ExcelApp.WorkSheets[1].Rows.PageBreak := 1;10) 在第8列之前删除分页符:
ExcelApp.ActiveSheet.Columns[4].PageBreak := 0;11) 指定边框线宽度:
ExcelApp.ActiveSheet.Range[ 'B3:D4' ].Borders[2].Weight := 3;
1-左 2-右 3-顶 4-底 5-斜( \ ) 6-斜( / )12) 清除第一行第四列单元格公式:
ExcelApp.ActiveSheet.Cells[1,4].ClearContents;13) 设置第一行字体属性:
ExcelApp.ActiveSheet.Rows[1].Font.Name := '隶书';
ExcelApp.ActiveSheet.Rows[1].Font.Color := clBlue;
ExcelApp.ActiveSheet.Rows[1].Font.Bold := True;
ExcelApp.ActiveSheet.Rows[1].Font.UnderLine := True;14) 进行页面设置:a.页眉:
ExcelApp.ActiveSheet.PageSetup.CenterHeader := '报表演示';
b.页脚:
ExcelApp.ActiveSheet.PageSetup.CenterFooter := '第&P页';
c.页眉到顶端边距2cm:
ExcelApp.ActiveSheet.PageSetup.HeaderMargin := 2/0.035;
d.页脚到底端边距3cm:

c.从A1位置开始粘贴:

ExcelWorkSheet1.ConnectTo(Temp_WorkSheet);
End;
6) 打开已存在的工作簿:

ExcelApplication1.ActiveWorkBook.Saved := True;25) 关闭工作簿:
ExcelApplication1.WorkBooks.Close;26) 退出 Excel:
ExcelApplication1.Quit;
ExcelApplication1.Disconnect;(三) 使用Delphi 控制Excle二维图
在Form中分别放入ExcelApplication, ExcelWorkbook和ExcelWorksheet
var asheet1,achart, range:variant;1)选择当第一个工作薄第一个工作表
asheet1:=ExcelApplication1.Workbooks[1].Worksheets[1];2)增加一个二维图
achart:=asheet1.chartobjects.add(100,100,200,200);3)选择二维图的形态
achart.chart.charttype:=4;4)给二维图赋值
series:=achart.chart.seriescollection;
range:=sheet1!r2c3:r3c9;
series.add(range,true);
5)加上二维图的标题
achart.Chart.HasTitle:=True;
achart.Char
明天叫020918.XLS
const
adClipString = 2;
ColumnDelimeter = ';';
RowDelimeter = #13#10;
var
s: string;
fs: TFileStream;
begin
// adoqTemp: TADOQuery;
adoqTemp.Open;
s := adoqTemp.Recordset.GetString(adClipString, adoqUserInfo.RecordCount,
ColumnDelimeter, RowDelimeter, '');
// export to a txt file
fs := TFileStream.Create('Temp.CSV', fmCreate);
try
fs.WriteBuffer(s[1], Length(s));
finally
fs.Free;
end;
ShowMessage('Temp.CSV has been saved');
end;
这样存的就是你要的日期格式的了!
与
aSheet.SaveAs('d:\qqq.xls');都可以保存,那区别是什么?
