Innosetup打包自动下载.net framework 动态库及替换卸载程序图标.

    1. 在使用了一段时间微软自带的安装包打包工具后,总感觉不太顺利,于是便想着找一种更简单稳定的打包工具,这类工具其实还不少,最终经过各种考量,我们选择了 InnoSetup ,

      该工具是一个完全免费的Windows打包工具,涉及的功能比较全面,并且采用脚本式编辑,完美支持 Pascal 语言.本文简单描述一下如何自动下载安装 .net framework 框架 及更新卸图标的小技巧,当然本文部分内容借鉴了网上一部分的解决方案.在此整理一下已备忘同时分享给有类似需求的朋友.

    2. 替换卸载程序图标
                   该工具制作的安装包,默认生成的卸载程序使用的是和安装程序一样的图标,这样感觉不够直观,可通过 "UpdateIcon.dll" 插件完成. 如下脚本所示.  
      [Files]
      Source: "UpdateIcon.dll"; Flags: dontcopy
      Source: "uninstall.ico"; Flags: dontcopy [Icons]
      Name: "{group}\卸载"; Filename: "{uninstallexe}" [Code]
      function UpdateIcon(const hWnd: Integer; const exeFileName, exeIcon, IcoFileName: String; wlangID: DWORD): Boolean;
      external 'UpdateIcon@files:UpdateIcon.dll stdcall'; //替换卸载图标
      function UpdateUninstIcon(const IcoFileName: String): Boolean;
      begin
      Result:= UpdateIcon(MainForm.Handle, '', '', IcoFileName, );
      end; //安装步骤进行开始替换卸载图标
      procedure CurStepChanged(CurStep: TSetupStep);
      var
      sIcon: String;
      begin
      if CurStep=ssInstall then
      begin
      sIcon:= ExpandConstant('{tmp}\uninstall.ico'); //定义卸载图标
      ExtractTemporaryFile(ExtractFileName(sIcon)); //释放卸载图标
      UpdateUninstIcon(sIcon);//替换卸载图标
      end;
      end;
    3. 自动下载.net framework 组件并安装 
             可通过 “isxdl.dll” 扩展实现,动态从网络上添加一个待下载的文件,并在下载完之后自动运行.见如下示例.
    4. [Code]
      var
      dotNetDownloadNeeded: boolean;
      dotNetLocalPath:string; procedure isxdl_AddFile(URL, Filename: PAnsiChar);
      external 'isxdl_AddFile@files:isxdl.dll stdcall';
      function isxdl_DownloadFiles(hWnd: Integer): Integer;
      external 'isxdl_DownloadFiles@files:isxdl.dll stdcall';
      function isxdl_SetOption(Option, Value: PAnsiChar): Integer;
      external 'isxdl_SetOption@files:isxdl.dll stdcall'; //检测是否存在特定版本的.net framework
      function IsDotNetDetected(version: string; service:cardinal): boolean;
      // Indicates whether the specified version and service pack of the .NET Framework is installed.
      //
      // version -- Specify one of these strings for the required .NET Framework version:
      // 'v1.1.4322' .NET Framework 1.1
      // 'v2.0.50727' .NET Framework 2.0
      // 'v3.0' .NET Framework 3.0
      // 'v3.5' .NET Framework 3.5
      // 'v4\Client' .NET Framework 4.0 Client Profile
      // 'v4\Full' .NET Framework 4.0 Full Installation
      // 'v4.5' .NET Framework 4.5
      //
      // service -- Specify any non-negative integer for the required service pack level:
      // 0 No service packs required
      // 1, 2, etc. Service pack 1, 2, etc. required
      var
      key: string;
      install, release, serviceCount: cardinal;
      check45, success: boolean;
      begin
      // .NET 4.5 installs as update to .NET 4.0 Full
      if version = 'v4.5' then begin
      version := 'v4\Full';
      check45 := true;
      end else
      check45 := false; // installation key group for all .NET versions
      key := 'SOFTWARE\Microsoft\NET Framework Setup\NDP\' + version; // .NET 3.0 uses value InstallSuccess in subkey Setup
      if Pos('v3.0', version) = then begin
      success := RegQueryDWordValue(HKLM, key + '\Setup', 'InstallSuccess', install);
      end else begin
      success := RegQueryDWordValue(HKLM, key, 'Install', install);
      end; // .NET 4.0/4.5 uses value Servicing instead of SP
      if Pos('v4', version) = then begin
      success := success and RegQueryDWordValue(HKLM, key, 'Servicing', serviceCount);
      end else begin
      success := success and RegQueryDWordValue(HKLM, key, 'SP', serviceCount);
      end; // .NET 4.5 uses additional value Release
      if check45 then begin
      success := success and RegQueryDWordValue(HKLM, key, 'Release', release);
      success := success and (release >= );
      end; result := success and (install = ) and (serviceCount >= service);
      end; //准备安装.net framework需要的条件(本地还是联网)
      function PreInstallDotNet(dotNetName:string;dotNetDownloadUrl:string):boolean;
      begin
      if (not IsAdminLoggedOn()) then begin
      MsgBox('您电脑安装 Microsoft .NET Framework 需要管理员权限', mbInformation, MB_OK);
      Result := false;
      end else begin

      if not FileExists(dotNetLocalPath) then begin
      isxdl_AddFile(dotNetDownloadUrl, dotNetLocalPath);
      dotNetDownloadNeeded := true;
      end;
      end; SetIniString('install', 'dotnetRedist', dotNetLocalPath, ExpandConstant('{tmp}\dep.ini'));
      end; end; //执行安装.net framework
      function DoInstallDotNet():boolean;
      var
      hWnd: Integer;
      ResultCode: Integer;
      begin
      result := true;
      hWnd := StrToInt(ExpandConstant('{wizardhwnd}')); // don’t try to init isxdl if it’s not needed because it will error on < ie 3
      if dotNetDownloadNeeded then begin
      isxdl_SetOption('label', '正在下载 Microsoft .NET Framework');
      isxdl_SetOption('des-c-r-i-p-tion', '您还未安装Microsoft .NET Framework. 请您耐心等待几分钟,下载完成后会安装到您的的计算机中。');
      if isxdl_DownloadFiles(hWnd) = then result := false;
      end; if result = true then begin
      if Exec(ExpandConstant(dotNetLocalPath), '/qb', '', SW_SHOW, ewWaitUntilTerminated, ResultCode) then begin
      // handle success if necessary; ResultCode contains the exit code
      if not (ResultCode = ) then begin
      result := false;
      end;
      end else begin

      end;
      end;
      end;
      end;

      关于通用
            可以将以上两个小功能点分别保存为独立的innosetup 脚本文件(“.iss”),然后在主安装包脚本中引入这两个文件.如下所示.

    5. #include "dotnetSetup.iss"
      #include "updateuninstallIco.iss"
