仅将Inno Setup UI用作自解压器-无需安装 [英] Use Inno Setup UI as a self-extractor only - No installation

问题描述

我将Inno Setup用于许多标准"安装程序，但是对于此任务，我需要提取一堆临时文件，运行其中一个临时文件，然后将其删除并退出安装程序(实际上没有安装任何东西).

I use Inno Setup for many "standard" installers, but for this task I need to extract a bunch of temp files, run one of them, then remove them and exit the installer (without actually installing anything).

基本上，我希望在不使用安装程序"的情况下创建一个自解压程序，并且正在寻求通过inno设置获得最佳用户体验的方法.

Basically I'm looking to make a self-extractor with without it being an "installer", and am after the best user experience possible with inno setup.

我有以下几乎可以正常工作的代码:

I have the following code which almost works fine:

[Files]
Source: "dist\*"; Flags: recursesubdirs ignoreversion dontcopy;

[Code]
function InitializeSetup(): Boolean;
var
  ResultCode: Integer;
begin
  Result := True;
  MsgBox('Please wait a minute or two...', mbInformation, MB_OK);
  ExtractTemporaryFiles('{tmp}\*');
  Exec(ExpandConstant('{tmp}\MyScript.exe'), '', '', SW_HIDE, ewWaitUntilTerminated, ResultCode);
  Abort();
end;

问题在于，我在这里能做的最好的事情是显示一个消息框请稍等一两分钟..."，用户单击[确定]，然后等待，因为屏幕上没有任何显示的内容，但没有任何反应全部，然后MyScript.exe开始.

The problem is that the best I can do here is show a message box "Please wait a minute or two...", the user clicks [Ok], then waits as nothing appears to happen with nothing on-screen at all, then MyScript.exe starts.

我想要的是一个向导页面，该页面带有npbstMarquee样式进度条，上面写着请稍等，正在提取临时文件..."，然后在提取文件并启动脚本后消失.

What I'd like instead is a Wizard page saying "Please wait as temporary files are extracted..." with a npbstMarquee style progress bar, then is disappears once the files are extracted and my script starts.

我不认为有一种方法可以告诉Inno Setup在ExtractTemporaryFiles()进行时显示进度条(这是理想的选择)，并将其处理到自定义向​​导页面中会让我感到困惑.

I don't think there's a way to tell Inno Setup to display a progress bar while ExtractTemporaryFiles() is going (which would be ideal) and working this into a custom wizard page has got me baffled.

推荐答案

• 将文件安装"到{tmp}，而不是使用ExtractTemporaryFiles;
• 执行从Run部分提取到{tmp}的文件(或在安装文件后使用AfterInstall参数或CurStepChanged触发Pascal脚本代码)；
• 将 Uninstallable 设置为no；
• 将 CreateAppDir 设置为no;
• 使用 [Messages]部分来编辑向导文本以安装者为中心，满足您的需求.
• "Install" the files to {tmp}, instead of using ExtractTemporaryFiles;
• Execute the files extracted to {tmp} from Run section (or use AfterInstall parameter or CurStepChanged to trigger Pascal Script code after files are installed);
• Set Uninstallable to no;
• Set CreateAppDir to no;
• Use [Messages] section to edit the wizard texts that are too installer-centric for your needs.

[Setup]
Uninstallable=no
CreateAppDir=no

[Files]
Source: "dist\*"; DestDir: {tmp}; Flags: recursesubdirs

[Run]
FileName: "{tmp}\MyScript.exe"

注意:

• {tmp}文件夹在安装程序"关闭时自动删除；
• 在安装到新的空文件夹时，不需要ignoreversion标志.
• The {tmp} folder gets automatically deleted, when the "installer" is closing;
• No need for ignoreversion flag, when installing to new empty folder.
