procedure TForm1.Button1Click(Sender: TObject);

var
S:string;
begin
if MessageDlg('提示框',mtInformation,[mbok,mbyes],0)=mryes then
messagebeep(MB_ICONEXCLAMATION);
end;

TMsgDlgType = (mtWarning, mtError, mtInformation, mtConfirmation, mtCustom);

TMsgDlgBtn = (mbYes, mbNo, mbOK, mbCancel, mbAbort, mbRetry, mbIgnore,
mbAll, mbNoToAll, mbYesToAll, mbHelp);

const
mrNone = 0;
mrOk = idOk;
mrCancel = idCancel;
mrAbort = idAbort;
mrRetry = idRetry;
mrIgnore = idIgnore;
mrYes = idYes;
mrNo = idNo;
mrAll = mrNo + 1;
mrNoToAll = mrAll + 1;
mrYesToAll = mrNoToAll + 1;

MessageDlg()信息的汉化 
Delphi中的常量都放在consts.pas中,修改它可以达到汉化的目的.如: 
MessageDlg()显示的窗口标题及其中的 
按钮标题都是英文,虽然不影响使用,但在一个中文软件中总显得有些不协调. 
为此在consts.pas中查找以下内容: 
"SMsgDlgWarning" 
把

---

 

SMsgDlgWarning = 'Warning';
SMsgDlgError = 'Error';
SMsgDlgInformation = 'Information';
SMsgDlgConfirm = 'Confirm';
SMsgDlgYes = '&Yes';
SMsgDlgNo = '&No';
SMsgDlgOK = 'OK';
SMsgDlgCancel = 'Cancel';
SMsgDlgHelp = '&Help';
SMsgDlgHelpNone = 'No help available';
SMsgDlgHelpHelp = 'Help';
SMsgDlgAbort = '&Abort';
SMsgDlgRetry = '&Retry';
SMsgDlgIgnore = '&Ignore';
SMsgDlgAll = '&All';
SMsgDlgNoToAll = 'N&o to All';
SMsgDlgYesToAll = 'Yes to &All';

---

 

改成

---

SMsgDlgWarning = '警告';
SMsgDlgError = '错误';
SMsgDlgInformation = '提示';
SMsgDlgConfirm = '确认';
SMsgDlgYes = '是(&Y)';
SMsgDlgNo = '不(&N)';
SMsgDlgOK = '确定';
SMsgDlgCancel = '取消';
SMsgDlgHelp = '帮助(&H)';
SMsgDlgHelpNone = '没有该帮助信息';
SMsgDlgHelpHelp = '帮助';
SMsgDlgAbort = '放弃(&A)';
SMsgDlgRetry = '重试(&R)';
SMsgDlgIgnore = '忽略(&I)';
SMsgDlgAll = '全部(&A)';
SMsgDlgNoToAll = '全都不(&O)';
SMsgDlgYesToAll = '全都是(&A)';

然后重新编译Consts.pas,把Consts.duc 
拷到delphi的lib和slib子目录下,就一劳永逸啦!
