unit1.pas

目前最简单的10和16进制互相转化的代码了

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Edit2: TEdit;
    Button1: TButton;
    Edit3: TEdit;
    Button2: TButton;
    Edit4: TEdit;
    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);
begin
  if Copy(Edit1.Text,1,1)<>'$' then
   begin
Edit1.Text:= '$' + Edit1.Text;
Edit2.Text:=IntToStr(StrToInt(Edit1.Text)); //这里要求16进制前加$号
Edit3.Text:=IntToStr(StrToInt(Edit2.Text) + 1);
   end
   else
   begin
Edit2.Text:=IntToStr(StrToInt(Edit1.Text)); //这里要求16进制前加$号
Edit3.Text:=IntToStr(StrToInt(Edit2.Text) + 1);
   end;
end;

procedure TForm1.Button2Click(Sender: TObject);
var
i:Integer;
begin
Edit4.Text:=Format('%x',[StrToInt(Edit3.Text)]);  //[]内为integer类型
i:=Length(Edit4.text);
 case i of
 6:Edit4.Text:='$00' + Edit4.Text;
 end;
end;
