示例中，dbgrid(DBGrid1)具有一个弹出菜单，它给出两个选项："Send to Excel" 和 "Copy". 下面给出用到的方法: //注意：下面的方法必须包含 ComObj, Excel97 单元 //----------------------------------------------------------- // if toExcel = false, export dbgrid contents to the Clipboard // if toExcel = true, export dbgrid to Microsoft Excel procedure ExportDBGrid(toExcel: Boolean); var bm: TBook; col, row: Integer; sline: String; mem: TMemo; ExcelApp: Variant; begin Screen.Cursor := crHourglass; DBGrid1.DataSource.DataSet.DisableControls; bm := DBGrid1.DataSource.DataSet.GetBook; DBGrid1.DataSource.DataSet.First;
// create the Excel object if toExcel then begin ExcelApp := CreateOleObject('Excel.Application'); ExcelApp.WorkBooks.Add(xlWBatWorkSheet); ExcelApp.WorkBooks[1].WorkSheets[1].Name := 'Grid Data'; end;
// First we send the data to a memo // works faster than doing it directly to Excel mem := TMemo.Create(Self); mem.Visible := false; mem.Parent := MainForm; mem.Clear; sline := '';
// add the info for the column names for col := 0 to DBGrid1.FieldCount-1 do sline := sline + DBGrid1.Fields[col].DisplayLabel + #9; mem.Lines.Add(sline);
// get the data into the memo for row := 0 to DBGrid1.DataSource.DataSet.RecordCount-1 do begin sline := ''; for col := 0 to DBGrid1.FieldCount-1 do sline := sline + DBGrid1.Fields[col].AsString + #9; mem.Lines.Add(sline); DBGrid1.DataSource.DataSet.Next; end;
// we copy the data to the clipboard mem.SelectAll; mem.CopyToClipboard;
// if needed, send it to Excel // if not, we already have it in the clipboard if toExcel then begin ExcelApp.Workbooks[1].WorkSheets['Grid Data'].Paste; ExcelApp.Visible := true; end;

please send me one
btw:有无将execel数据导入dbgrid或者sql的好方法啊
