Delphi2007自己定义了TBytes
type
  TBytes = array of Byte;

在SysUtils单元下，Delphi7中没有。

Answer 3

unit uUIBaseFun;interfaceuses
  Windows, SysUtils, StrUtils, DateUtils, Controls, Forms, uComPram, udmCommon,
  EZDSLHsh, GridsEh, DBGridEh, DBClient, IdGlobal, StdCtrls;
  
function UILogin: Boolean;function UISelectSvr: Boolean;procedure UIAbort;procedure UICloseAbout;function InitSocketConnection: Boolean;procedure InitDBGridColumeTitle(Grid: TDBGRIDEH; TableName: string);procedure InitDBGridColumeTitle_BJDB(Grid: TDBGRIDEH; TableName: string);function EnCryptSFile(EnPack: TBytes): string;//这里就错了

Answer 4

Delphi7中没有，你可以修改成下面这样：unit uUIBaseFun;interfaceuses
  Windows, SysUtils, StrUtils, DateUtils, Controls, Forms, uComPram, udmCommon,
  EZDSLHsh, GridsEh, DBGridEh, DBClient, IdGlobal, StdCtrls;
  
type
  TBytes = array of Byte;function UILogin: Boolean;function UISelectSvr: Boolean;procedure UIAbort;procedure UICloseAbout;function InitSocketConnection: Boolean;procedure InitDBGridColumeTitle(Grid: TDBGRIDEH; TableName: string);procedure InitDBGridColumeTitle_BJDB(Grid: TDBGRIDEH; TableName: string);function EnCryptSFile(EnPack: TBytes): string;//这里就错了
