其实,以上程序还有一个问题没有解决,就是当你输入大于32位的数值时程序将会出错,这个问题留待以后基础打牢点再解决了,呵呵。。
unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TForm1 = class(TForm) Edit1: TEdit; StaticText1: TStaticText; //这组件跟标签label效果差不多 StaticText2: TStaticText; Edit2: TEdit; Button1: TButton; Button2: TButton; procedure Button1Click(Sender: TObject); procedure Button2Click(Sender: TObject); private { Private declarations } public { Public declarations } end; var Form1: TForm1; implementation {$R *.dfm} procedure TForm1.Button1Click(Sender: TObject); //都是delphi自带函数,没什么好说的 var a:Integer; begin a:=StrToInt(Edit1.Text); Edit2.Text:=IntToHex(a,1); end; procedure TForm1.Button2Click(Sender: TObject); //都是delphi自带函数,没什么好说的 var i:Integer; begin i:=strtoint('$'+(Edit2.Text)); //加'$'后,原本的字符串就成了16进制数 Edit1.Text:=IntToStr(i); end; end.
