博客给出了两个与DBGrid数据复制相关的程序。CopyCurrentDBLine程序用于复制当前DBGrid行数据到剪贴板，CopyDBData程序则可复制DBGrid的所有数据到剪贴板，涉及Integer和String类型变量的使用。

procedure CopyCurrentDBLine(DBGrid: TDBGrid);
var
i: Integer;
Line: String;
begin
for i := 0 to DBGrid.Columns.Count - 1 do begin
    if Assigned(DBGrid.Columns.Grid.Fields[i]) then
      if Line = '' then
        Line := DBGrid.Columns.Grid.Fields[i].Text
      else
        Line := Line + ' ' + DBGrid.Columns.Grid.Fields[i].Text;
end;
Clipboard.SetTextBuf(pchar(Line));
end;
//感谢深思提供技术支持：）

procedure CopyDBData(DBGrid: TDBGrid);
const
CRLF = #13#10;
var
i: Integer;
Lines: String;
BookMark: Pointer;
begin
BookMark := DBGrid.DataSource.DataSet.GetBookmark;
DBGrid.DataSource.DataSet.First;

while not DBGrid.DataSource.DataSet.Eof do begin
    for i := 0 to DBGrid.Columns.Count - 1 do begin
      if Assigned(DBGrid.Columns.Grid.Fields[i]) then
        if Lines = '' then
          Lines := DBGrid.Columns.Grid.Fields[i].Text
        else
          if i = 0 then
            Lines := Lines + DBGrid.Columns.Grid.Fields[i].Text
          else
            Lines := Lines + ' ' + DBGrid.Columns.Grid.Fields[i].Text;
    end;
    Lines := Lines + CRLF;
    DBGrid.DataSource.DataSet.Next;
end;
ClipBoard.SetTextBuf(PChar(Lines));
DBGrid.DataSource.DataSet.GotoBookmark(BookMark);
end;
