"a","b","c"
可能我們並不希望它這樣顯示,有可能希望它顯示成種狀態
a,b,c
如果想這樣,我們可以修改DBGRIDEH裡面的DBGridEhImpExp.pas文件
具體修改如下:增加一個自己的導出到CSV的類
{ TMyDBGridEhExportAsCVS }
TMyDBGridEhExportAsCVS = class(TDBGridEhExportAsText)
private
FSeparator: Char;
protected
procedure CheckFirstCell; override;
procedure WriteTitle(ColumnsList: TColumnsEhList); override;
procedure WriteDataCell(Column: TColumnEh; FColCellParamsEh: TColCellParamsEh); override;
procedure WriteFooterCell(DataCol, Row: Integer; Column: TColumnEh; AFont: TFont;
Background: TColor; Alignment: TAlignment; Text: String); override;
public
constructor Create; override;
property Separator: Char read FSeparator write FSeparator;
end;
{ TMyDBGridEhExportAsCVS }
procedure TMyDBGridEhExportAsCVS.CheckFirstCell;
var s: String;
begin
if FirstCell = False then
begin
s := Separator;
StreamWriteString(Stream, s);
// Stream.Write(PChar(s)^, Length(s))
end else
FirstCell := False;
end;
constructor TMyDBGridEhExportAsCVS.Create;
begin
Separator := ',';
inherited Create;
end;
procedure TMyDBGridEhExportAsCVS.WriteDataCell(Column: TColumnEh; FColCellParamsEh: TColCellParamsEh);
var s: String;
begin
CheckFirstCell;
s := FColCellParamsEh.Text;
StreamWriteString(Stream, s);
// Stream.Write(PChar(s)^, Length(s));
end;
procedure TMyDBGridEhExportAsCVS.WriteFooterCell(DataCol, Row: Integer;
Column: TColumnEh; AFont: TFont; Background: TColor;
Alignment: TAlignment; Text: String);
var s: String;
begin
CheckFirstCell;
s := Text;
StreamWriteString(Stream, s);
// Stream.Write(PChar(s)^, Length(s));
end;
procedure TMyDBGridEhExportAsCVS.WriteTitle(ColumnsList: TColumnsEhList);
var i: Integer;
s: String;
begin
CheckFirstRec;
for i := 0 to ColumnsList.Count - 1 do
begin
s := ColumnsList[i].Title.Caption;
if i <> ColumnsList.Count - 1 then
s := s + Separator;
StreamWriteString(Stream, s);
// Stream.Write(PChar(s)^, Length(s));
end;
end;
Good luck!
