程序关联实现

程序中readme是个.sos文件，点吉它实现如下：

基本实现如下：

unit Unit1;

interface

uses

Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

Dialogs,

Registry,shlobj, StdCtrls, ExtCtrls;

type

TForm1 = class(TForm)

Memo1: TMemo;

Panel1: TPanel;

Button1: TButton;

procedure Button1Click(Sender: TObject);

procedure FormCreate(Sender: TObject);

private

procedure reg;

{ Private declarations }

public

{ Public declarations }

end;

var

Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.reg;

var

reg: TRegistry;

begin

reg := TRegistry.Create;

reg.RootKey := HKEY_CLASSES_ROOT;

reg.OpenKey('.sos', true);

reg.WriteString('', 'myzip');

reg.CloseKey;

reg.OpenKey('myzip\shell\open\command', true);

//用于打开.sos文件的可执行程序

reg.WriteString('', '"' + application.ExeName + '" "%1"');

reg.CloseKey;

reg.OpenKey('myzip\DefaultIcon',true);

//取当前可执行程序的图标为.sos文件的图标

reg.WriteString('',''+application.ExeName+',0');

reg.Free;

//立即刷新

SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, nil, nil);

end;

procedure TForm1.Button1Click(Sender: TObject);

begin

reg;

end;

procedure TForm1.FormCreate(Sender: TObject);

var

sFile: string;

begin

if ParamCount > 0 then

begin

(* 取得参数内容 *)

sFile := ParamStr(1);

if LowerCase(ExtractFileExt(sFile))='.sos' then memo1.Lines.LoadFromFile(sfile);

end;

end;

end.
