Inno Setup在所有用户的所有桌面上创建单独的快捷方式 [英] Inno Setup Create individual shortcuts on all desktops of all users

问题描述

我正在使用Inno Setup在用户桌面上创建快捷方式:

Name: "{commondesktop}\Setup"; Filename: "{app}\Setup.exe"; WorkingDir: "{pf}\Program"; IconFilename: "{app}\Setup.ico"

但是没有管理员权限的用户无法删除此快捷方式，如何向普通用户授予权限以删除此图标?应该在每个用户的桌面上创建图标，但是用户应该有权删除它.

解决方案

{commondesktop}快捷方式在通用桌面上共享.因此，该快捷方式只有一个副本.

如果允许用户删除，则当一个用户删除该图标时，该图标将被其他用户删除.这就是为什么不允许普通用户修改/删除共享快捷方式.

虽然您可以向所有用户授予对该快捷方式的删除权限，但这不是您应该做的.

如果每台计算机仅由一个用户使用，则将图标安装到userdesktop而不是commondestop.但这仅在该用户(而非管理员)实际运行安装程序时才有效.有关此问题的一般讨论，请参见为以管理员身份运行的Inno Setup安装程序为当前登录用户安装应用程序. >

没有简单的方法将图标安装到所有桌面.您必须使用Pascal Scripting并迭代所有配置文件.

简便的方法是迭代C:\Users的子文件夹，在每个用户的子文件夹的Desktop子文件夹中创建快捷方式:

 procedure CurStepChanged(CurStep: TSetupStep);
var
  UsersPath: string;
  CommonDesktopShortPath: string;
  DesktopPath: string;
  ShortcutPath: string;
  FindRec: TFindRec;
  ShortcutsCount: Integer;
begin
  { Once the files are installed }
  if CurStep = ssPostInstall then
  begin
    Log('Creating shortcuts');
    { Assuming the common users root (typically C:\Users) is two level up }
    { from the current user desktop folder }
    UsersPath :=
      AddBackslash(ExtractFilePath(RemoveBackslash(ExtractFilePath(
        RemoveBackslash(ExpandConstant('{userdesktop}'))))));
    Log(Format('Users root [%s]', [UsersPath]));
    CommonDesktopShortPath := GetShortName(ExpandConstant('{commondesktop}'));
    Log(Format('Common desktop [%s]', [CommonDesktopShortPath]));

    ShortcutsCount := 0;

    { Iterate all users }
    if FindFirst(UsersPath + '*', FindRec) then
    begin
      try
        repeat
          { Just directories, not interested in files }
          if FindRec.Attributes and FILE_ATTRIBUTE_DIRECTORY <> 0 then
          begin
            { Check if there is a Desktop subfolder }
            DesktopPath := UsersPath + FindRec.Name + '\Desktop';
            if DirExists(DesktopPath) then
            begin
              if CompareText(CommonDesktopShortPath, GetShortName(DesktopPath)) = 0 then
              begin
                Log(Format('Skipping common desktop [%s]', [DesktopPath]));
              end
                else
              begin
                ShortcutPath := DesktopPath + '\My Program.lnk';
                Log(Format(
                  'Found desktop folder for user [%s], creating shortcut [%s]', [
                  FindRec.Name, ShortcutPath]));
                try
                  ShortcutPath := CreateShellLink(
                    ShortcutPath, 'My Program', ExpandConstant('{app}\MyProg.exe'), '',
                    ExpandConstant('{app}'), '', 0, SW_SHOWNORMAL);
                  Log(Format('Shortcut [%s] created', [ShortcutPath]));
                  Inc(ShortcutsCount);
                except
                  Log(Format('Failed to create shortcut: %s', [GetExceptionMessage]));
                end;
              end;
            end;
          end;
        until not FindNext(FindRec);
      finally
        FindClose(FindRec);
      end;

      Log(Format('%d shortcuts created', [ShortcutsCount]));
    end
      else
    begin
      Log(Format('Error listing [%s]', [UsersPath]));
    end;
  end;
end;

仅当台式机位于本地且位于公共位置时，该代码才有效.

如果您需要更强大的解决方案，则可以迭代

中列出的配置文件

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

或使用WMI查询，例如:

 SELECT * FROM Win32_UserAccount WHERE localAccount = true and disabled = false
 

I'm creating a shortcut on users Desktop with Inno Setup:

Name: "{commondesktop}\Setup"; Filename: "{app}\Setup.exe"; WorkingDir: "{pf}\Program"; IconFilename: "{app}\Setup.ico"

But users, with no admin rights, cannot delete this Shortcut, how to grant permissions to regular users, to delete this icon? Icon should be created on every user's desktop, but user should have permission to delete it.

解决方案

The {commondesktop} shortcut is shared on a common desktop. So there's only one copy of the shortcut.

If you allow the users to delete, when one user deletes the icon, it's deleted for every other user. That's why regular users are not allowed to modify/delete shared shortcuts.

While you can grant a delete permission to all users to that shortcut, this is not what you should do.

If each machine is used by one user only, install the icon to userdesktop, not commondestop. But that works only if that user (not Administrator) actually run the installer. For a general discussion about this problem, see Installing application for currently logged in user from Inno Setup installer running as Administrator.

There's no easy way to install the icons to all desktops. You have to use Pascal Scripting and iterate all profiles.

Easy way is to iterate subfolders of C:\Users, creating a shortcut in Desktop subfolder of each user's subfolder:

procedure CurStepChanged(CurStep: TSetupStep);
var
  UsersPath: string;
  CommonDesktopShortPath: string;
  DesktopPath: string;
  ShortcutPath: string;
  FindRec: TFindRec;
  ShortcutsCount: Integer;
begin
  { Once the files are installed }
  if CurStep = ssPostInstall then
  begin
    Log('Creating shortcuts');
    { Assuming the common users root (typically C:\Users) is two level up }
    { from the current user desktop folder }
    UsersPath :=
      AddBackslash(ExtractFilePath(RemoveBackslash(ExtractFilePath(
        RemoveBackslash(ExpandConstant('{userdesktop}'))))));
    Log(Format('Users root [%s]', [UsersPath]));
    CommonDesktopShortPath := GetShortName(ExpandConstant('{commondesktop}'));
    Log(Format('Common desktop [%s]', [CommonDesktopShortPath]));

    ShortcutsCount := 0;

    { Iterate all users }
    if FindFirst(UsersPath + '*', FindRec) then
    begin
      try
        repeat
          { Just directories, not interested in files }
          if FindRec.Attributes and FILE_ATTRIBUTE_DIRECTORY <> 0 then
          begin
            { Check if there is a Desktop subfolder }
            DesktopPath := UsersPath + FindRec.Name + '\Desktop';
            if DirExists(DesktopPath) then
            begin
              if CompareText(CommonDesktopShortPath, GetShortName(DesktopPath)) = 0 then
              begin
                Log(Format('Skipping common desktop [%s]', [DesktopPath]));
              end
                else
              begin
                ShortcutPath := DesktopPath + '\My Program.lnk';
                Log(Format(
                  'Found desktop folder for user [%s], creating shortcut [%s]', [
                  FindRec.Name, ShortcutPath]));
                try
                  ShortcutPath := CreateShellLink(
                    ShortcutPath, 'My Program', ExpandConstant('{app}\MyProg.exe'), '',
                    ExpandConstant('{app}'), '', 0, SW_SHOWNORMAL);
                  Log(Format('Shortcut [%s] created', [ShortcutPath]));
                  Inc(ShortcutsCount);
                except
                  Log(Format('Failed to create shortcut: %s', [GetExceptionMessage]));
                end;
              end;
            end;
          end;
        until not FindNext(FindRec);
      finally
        FindClose(FindRec);
      end;

      Log(Format('%d shortcuts created', [ShortcutsCount]));
    end
      else
    begin
      Log(Format('Error listing [%s]', [UsersPath]));
    end;
  end;
end;

The code will work only, if the desktops are local and in common locations.

If you need a more robust solution, you can iterate profiles listed in

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

Or use a WMI query like:

SELECT * FROM Win32_UserAccount WHERE localAccount = true and disabled = false
