倾家荡产，求备份和恢复ACCESS的源码

Answer 1

ACCESS只有用COPY文件的方法来实现备份哟，你是要压缩和修复，是不是呀，有一个COMPACT方法可以实现压缩的

unit unAccessTools;interfaceuses Sysutils,ComObj,Dialogs;function DaoActive(var DaoObject:OleVariant):Boolean;
function DaoCompactDB(const FileName:string):Boolean;
function DaoRepairDB(const FileName:string):Boolean;implementationfunction DaoActive(var DaoObject:OleVariant):Boolean;
begin
  Result:=False;
  try
    DaoObject:=GetActiveOleObject('DAO.DBEngine.36');
    Result:=True;
  except
    try
      DaoObject:=CreateOleObject('DAO.DBEngine.36');
      Result:=True;
    except
      DaoObject:=Null;
    end;
  end;
end;//压缩Access数据库
function DaoCompactDB(const FileName:string):Boolean;
var
  db:OleVariant;
  TempFile:string;
begin
  Result:=False;
  try
    if not DaoActive(db) then
      Exit;
    try
      TempFile:=ExtractFilePath(FileName)+'msaTemp.mdb';
      db.CompactDatabase(FileName,TempFile);
      DeleteFile(FileName);
      RenameFile(TempFile,FileName);
      Result:=True;
    except
      on E:EOleException do
        ShowMessage(E.Message);
    end
  finally
    db:=Unassigned;
  end;
end;//修复Access数据库
function DaoRepairDB(const FileName:string):Boolean;
var
  db:OleVariant;
begin
  Result:=False;
  try
    if not DaoActive(db) then
      Exit;
    try
      db.RepairDatabase(FileName);
      Result:=True;
    except
      on E:EOleException do
        ShowMessage(E.Message);
    end
  finally
    db:=Unassigned;
  end;
end;end.

备份及恢复就只能COPY了，呵呵
