以下是详细说明

//ShowMessage:
begin
ShowMessage(‘提示内容’);      {标题默认工程名, 如: Proect1}

Application.Title := ‘警告’; {如果修改工程标题…}
ShowMessage(‘提示内容’);      {标题是’警告’}

ShowMessage(‘第一行’ + #13#10 + ‘第二行’); {提示信息换行}
ShowMessage(‘第一行’#13‘第二行’);     {也可以}
end;


//InputBox:
var
s: string;
begin
s := InputBox(‘标题’,‘提示信息’,‘默认输入’);
ShowMessage(s); //显示输入的内容
end;


//InputQuery:
var
s: string;
begin
InputQuery(‘标题’,‘提示信息’,s); //为字符串变量 S 输入值, 返回布尔型
ShowMessage(s); //显示输入的内容
end;


//MessageBox:
var
i: Integer;
begin
i := MessageBox(0,‘提示内容’,‘标题’,mrOk); //第一个参数一般用 Self.Handle, 0代表桌面

//可选参数  
//mrNone
//mrOk
//mrCancel
//mrAbort
//mrRetry
//mrIgnore
//mrYes
//mrNo
//mrAll
//mrNoToAll
//mrYesToAll

ShowMessage(IntToStr(i));

//还可以组合第四个参数以调用不同的图标:
MessageBox(0,‘提示内容’,‘标题’,mrOk + MB_ICONHAND);

//MB_ICONHAND
//MB_ICONQUESTION
//MB_ICONEXCLAMATION
//MB_ICONASTERISK
//MB_USERICON
//MB_ICONWARNING
//MB_ICONERROR
//MB_ICONINFORMATION
//MB_ICONSTOP
end;

//后来补充, 还是应该使用 API 的原有参数更好些:
{可选参数或它们的组合}

//MessageDlg:
var
i: Integer;
begin
MessageDlg(‘提示信息’,mtWarning,mbYesNo,0);

//第二个参数调用不同的图标:
//mtWarning
//mtError
//mtInformation
//mtConfirmation
//mtCustom

//第三个参数调用不同的按钮:
//mbYesNo = [mbYes, mbNo];
//mbYesNoCancel = [mbYes, mbNo, mbCancel];
//mbYesAllNoAllCancel = [mbYes, mbYesToAll, mbNo, mbNoToAll, mbCancel];
//mbOKCancel = [mbOK, mbCancel];
//mbAbortRetryIgnore = [mbAbort, mbRetry, mbIgnore];
//mbAbortIgnore = [mbAbort, mbIgnore];
//可以直接输入集合元素,譬如: MessageDlg(‘aaa’,mtWarning,[mbYes],1);

//第四个参数帮助ID, 没有添0
//还有重载的第5个参数是设定默认按钮
//如果要本地话显示需要修改源文件, 一般可以用 MessageBox 代替
end;


//MessageDlgPos:
begin
MessageDlgPos(‘提示信息’,mtCustom,mbYesNoCancel,0,400,100);
//比 MessageDlg 多出两个参数来控制显示位置
end;
