手头的法度须要批改注册表, 以让当前法度成为某格局的默认打开法度并接洽关系图标; Vista 之后须要经管员权限才干操纵注册表, 很麻烦, 所以有了下面的测验测验.
unit Unit1;
interface
uses
Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls;
type
TForm1 = class(TForm)
Memo1: TMemo;
Button1: TButton;
procedure FormCreate(Sender: TObject);
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{¥R .dfm}
uses System.IOUtils, Winapi.ShellAPI, Winapi.ShlObj; //RegApp 函数用到的单位
//接洽关系默认法度的函数
procedure RegApp(const aExt, aAppName, aAppPath: string);
const
nRegFmt = Windows Registry Editor Version 5.00 + sLineBreak +
[HKEY_CLASSES_ROOT\%0:s] + sLineBreak +
@=%1:s + sLineBreak +
[HKEY_CLASSES_ROOT\%1:s\DefaultIcon] + sLineBreak +

@=%3:s;
var
RegStr: string;
str3, str4: string;
RegTmpFile: string;
begin
str3 := aAppPath.Replace(\, \\);
str4 := Format(%s %%1, [str3]).Replace(, \);
RegStr := Format(nRegFmt, [aExt, aAppName, str3, str4]);
RegTmpFile := TPath.GetTempPath + RegTmp.reg;
with TStringList.Create do begin
Text := RegStr;
SaveToFile(RegTmpFile);
Free;
end;
Shellute(0, nil, PChar(RegTmpFile), nil, nil, SW_SHOWNORMAL);
SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, nil, nil); //刷新图标显示
end;
procedure TForm1.FormCreate(Sender: TObject);
var
S: string;
begin
S := ParamStr(1);
if FileExists(S) then Memo1.Lines.LoadFromFile(S);
end;
//履行注册函数; 履行后, 可随便批改一个文本文件的后缀为 tst, 然后双击测试
procedure TForm1.Button1Click(Sender: TObject);
begin
RegApp(.tst, MyApp1, Application.ExeName); //假定法度名称是 MyApp1, 要打开的文件的后缀是 .tst
end;
end.
我俩之间有着强烈的吸引力。短短几个小时后,我俩已经明白:我们的心是一个整体的两半,我俩的心灵是孪生兄妹,是知己。她让我感到更有活力,更完美,更幸福。即使她不在我身边,我依然还是感到幸福,因为她总是以这样或者那样的方式出现在我心头。——恩里克·巴里奥斯《爱的文明》
