是否可以使用Inno Setup“固定到开始菜单"? [英] Is it possible to 'Pin to start menu' using Inno Setup?

问题描述

我使用的是出色的Inno Setup安装程序，我注意到某些应用程序(通常来自Microsoft)已安装，并且其启动图标在开始菜单(在Windows 7中)中已经高度可见(固定"?).我是完全依赖最近使用的算法来使我的图标在开始"菜单中变大"吗，还是可以通过安装程序来升级我的应用程序?

I'm using the excellent Inno Setup installer and I notice that some Applications (often from Microsoft) get installed with their launch icon already highly visible ('pinned?') in the start menu (in Windows 7). Am I totally reliant on the most-recently-used algorithm for my icon to be 'large' in the start menu, or is there a way of promoting my application from the installer please?

推荐答案

可以固定程序，但不能正式固定程序.基于

It is possible to pin programs, but not officially. Based on a code posted in this thread (which uses the same way as described in the article linked by @Mark Redman) I wrote the following:

[Code]
#ifdef UNICODE
  #define AW "W"
#else
  #define AW "A"
#endif

const
  // these constants are not defined in Windows
  SHELL32_STRING_ID_PIN_TO_TASKBAR = 5386;
  SHELL32_STRING_ID_PIN_TO_STARTMENU = 5381;
  SHELL32_STRING_ID_UNPIN_FROM_TASKBAR = 5387;
  SHELL32_STRING_ID_UNPIN_FROM_STARTMENU = 5382;

type
  HINSTANCE = THandle;
  HMODULE = HINSTANCE;

  TPinDest = (
    pdTaskbar,
    pdStartMenu
  );

function LoadLibrary(lpFileName: string): HMODULE;
  external 'LoadLibrary{#AW}@kernel32.dll stdcall';
function FreeLibrary(hModule: HMODULE): BOOL;
  external '[e-mail] stdcall';
function LoadString(hInstance: HINSTANCE; uID: UINT;
  lpBuffer: string; nBufferMax: Integer): Integer;
  external 'LoadString{#AW}@user32.dll stdcall';

function TryGetVerbName(ID: UINT; out VerbName: string): Boolean;
var
  Buffer: string;
  BufLen: Integer;
  Handle: HMODULE;
begin
  Result := False;

  Handle := LoadLibrary(ExpandConstant('{sys}\Shell32.dll'));
  if Handle <> 0 then
  try
    SetLength(Buffer, 255);
    BufLen := LoadString(Handle, ID, Buffer, Length(Buffer));

    if BufLen <> 0 then
    begin
      Result := True;
      VerbName := Copy(Buffer, 1, BufLen);
    end;
  finally
    FreeLibrary(Handle);
  end;
end;

function ExecVerb(const FileName, VerbName: string): Boolean;
var
  I: Integer;
  Shell: Variant;
  Folder: Variant;
  FolderItem: Variant;
begin
  Result := False;

  Shell := CreateOleObject('Shell.Application');
  Folder := Shell.NameSpace(ExtractFilePath(FileName));
  FolderItem := Folder.ParseName(ExtractFileName(FileName));

  for I := 1 to FolderItem.Verbs.Count do
  begin
    if FolderItem.Verbs.Item(I).Name = VerbName then
    begin
      FolderItem.Verbs.Item(I).DoIt;
      Result := True;
      Exit;
    end;
  end;  
end;

function PinAppTo(const FileName: string; PinDest: TPinDest): Boolean;
var
  ResStrID: UINT;
  VerbName: string;
begin
  case PinDest of
    pdTaskbar: ResStrID := SHELL32_STRING_ID_PIN_TO_TASKBAR;
    pdStartMenu: ResStrID := SHELL32_STRING_ID_PIN_TO_STARTMENU;
  end;
  Result := TryGetVerbName(ResStrID, VerbName) and ExecVerb(FileName, VerbName);
end;

function UnpinAppFrom(const FileName: string; PinDest: TPinDest): Boolean;
var
  ResStrID: UINT;
  VerbName: string;
begin
  case PinDest of
    pdTaskbar: ResStrID := SHELL32_STRING_ID_UNPIN_FROM_TASKBAR;
    pdStartMenu: ResStrID := SHELL32_STRING_ID_UNPIN_FROM_STARTMENU;
  end;
  Result := TryGetVerbName(ResStrID, VerbName) and ExecVerb(FileName, VerbName);
end;

上面的代码首先从Shell32.dll库的字符串表中读取用于固定或取消固定应用程序的菜单项的标题.然后连接到Windows Shell，并连接到目标应用程序.路径会创建 Folder 对象，然后获取 FolderItem 对象，并在此对象上迭代所有可用动词，并检查它们的名称是否与从Shell32.dll库字符串表中读取的动词匹配.如果是这样，它将通过调用 DoIt 方法并退出迭代.

The above code first reads the caption of the menu item for pinning or unpinning applications from the string table of the Shell32.dll library. Then connects to the Windows Shell, and for the target app. path creates the Folder object, then obtains the FolderItem object and on this object iterates all the available verbs and checks if their name matches to the one read from the Shell32.dll library string table. If so, it invokes the verb item action by calling the DoIt method and exits the iteration.

以下是上述代码的一种可能用法，用于固定:

Here is a possible usage of the above code, for pinning:

if PinAppTo(ExpandConstant('{sys}\calc.exe'), pdTaskbar) then
  MsgBox('Calc has been pinned to the taskbar.', mbInformation, MB_OK);
if PinAppTo(ExpandConstant('{sys}\calc.exe'), pdStartMenu) then
  MsgBox('Calc has been pinned to the start menu.', mbInformation, MB_OK);

并取消固定:

if UnpinAppFrom(ExpandConstant('{sys}\calc.exe'), pdTaskbar) then
  MsgBox('Calc is not pinned to the taskbar anymore.', mbInformation, MB_OK);
if UnpinAppFrom(ExpandConstant('{sys}\calc.exe'), pdStartMenu) then
  MsgBox('Calc is not pinned to the start menu anymore.', mbInformation, MB_OK);

请注意，即使此代码可在Windows 7上运行(并且在我测试过的Windows 8.1上也可以将任务栏固定)，但这确实是一种骇人听闻的方法，因为没有正式的方法可以将程序程序化地固定到任务栏上，开始菜单.这是用户应自行选择的方式.

Please note that even though this code works on Windows 7 (and taskbar pinning also on Windows 8.1 where I've tested it), it is really hacky way, since there is no official way to programatically pin programs to taskbar, nor start menu. That's what the users should do by their own choice.
