在Inno Setup中，如何在安装和卸载时使用具有依赖性的DLL? [英] How to use DLLs with dependencies at install AND uninstall time in Inno Setup?

问题描述

我想在卸载应用程序时在我的.iss文件中导入两个dll.我找不到解决办法. 帮忙〜

I want to import two dlls in my .iss when uninstalled the app. I cannot find a way to do this. help~

procedure Installed();
external 'Installed@files:StatisticInstallInfo.dll,adcore.dll cdecl  setuponly ';

procedure Uninstalled();
external 'Uninstalled@{app}\StatisticInstallInfo.dll cdecl  uninstallonly';

我也想在过程Uninstalled中导入adcore.dll，但失败，如下所示；

I want import adcore.dll in procedure Uninstalled too.and it's failed as below shows;

[Files]
Source: {#MyDefaultPackDir}\adcore.dll; DestDir: "{app}"; Flags: ignoreversion
Source: {#MyDefaultPackDir}\StatisticInstallInfo.dll; DestDir: "{app}"; Flags: ignoreversion

[Code]
procedure Uninstalled();
external 'Uninstalled@files:StatisticInstallInfo.dll,adcore.dll cdecl  uninstallonly';

它不起作用.

推荐答案

运行安装程序时，Inno可以访问安装程序的内容，因此可以使用files:file1.dll,file2.dll语法提取所需的任何文件.

When the installer is running, Inno has access to the contents of the setup, and so can extract any files needed using the files:file1.dll,file2.dll syntax.

在卸载时，Inno不再具有访问安装程序内容的权限，因此它需要依赖您在安装时使用常规[Files]条目提取的任何内容.因此，它不再关心依赖项，而是由您自己决定.

At uninstall time, Inno no longer as access to the contents of the setup so it needs to rely on anything you extracted at install time using a normal [Files] entry. Because of this, it no longer cares about the dependencies and leaves that up to you.

[Files]
Source: "StatisticInstallInfo.dll"; DestDir: "{app}"
Source: "adcore.dll"; DestDir: "{app}"

[Code]
procedure Installed();
external 'Installed@files:StatisticInstallInfo.dll,adcore.dll cdecl setuponly';

procedure Uninstalled();
external 'Uninstalled@{app}\StatisticInstallInfo.dll cdecl uninstallonly';

根据何时调用该函数(如果在安装本身之后)，可以取消files:...语法，在两种情况下都只需使用{app}\StatisticInstallInfo.dll.

Depending on when you call that function (if after the install itself) you can scrap the files:... syntax and just use {app}\StatisticInstallInfo.dll in both cases.
