PreviewToExcel := TExcelApplication.Create(Self);
PreviewToExcel.Connect;
PreviewToExcel.Workbooks.Add(NULL, 0);
RangeE := PreviewToExcel.ActiveCell;
for I := 0 to aDataSet.Fields.Count - 1 do
begin
RangeE.Value := aDataSet.Fields[I].DisplayLabel;
RangeE := RangeE.Next;
end;
aDataSet.DisableControls;
try
Bookmark := aDataSet.Bookmark;
try
aDataSet.First;
Row := 2;
while not aDataSet.EOF do
begin
RangeE := PreviewToExcel.Range['A' + IntToStr(Row), 'A' + IntToStr(Row)];
for I := 0 to aDataSet.Fields.Count - 1 do
begin
RangeE.Value := aDataSet.Fields[I].AsString;
RangeE := RangeE.Next;
end;
aDataSet.Next;
Inc(Row);
end;
finally
aDataSet.Bookmark := Bookmark;
end;
finally
aDataSet.EnableControls;
end;
RangeE := PreviewToExcel.Range['A1', chr(64 + aDataSet.Fields.Count) + IntToStr(Row - 1)];
RangeE.AutoFormat(8, NULL, NULL, NULL, NULL, NULL, NULL);
PreviewToExcel.Visible[0] := True;
PreviewToExcel.Disconnect;
end;
