Question

我的要求是，每个语言环境（语言）都有特定的文件（Dll，Chms等）。我需要根据语言环境加载这些文件并生成安装程序。并且在卸载时，我也应该从traget目录中卸载这些文件。

这是我在.onInit函数中所做的工作，使用GetUserDefaultUILanguage（）我正在获取语言环境并检查此语言环境并在该语言环境下加载文件。

这是正确的方法吗？请提供有关此代码的任何建议。

我们还需要在“ Languages”部分之前使用“ Pages”部分吗？

因为我在编译时收到警告，请在;语言部分之前使用;页面部分。

以下是我编写的代码段：

; LocaleDlls.nsi
;
;
; It will install LocaleDlls.nsi into a directory that the user selects.

;--------------------------------
!include LogicLib.nsh
 !include "MUI2.nsh"
; The name of the installer in the path C:\Program Files\LocaleDlls
Name "LocaleDlls"

; The file to write  in the path E:\Code\PCPE\NULLSOFT\src
OutFile "LocaleDlls.exe"

; The default installation directory in the path C:\Program Files\LocaleDlls
InstallDir $PROGRAMFILES\LocaleDlls

; Registry key to check for directory (so if you install again, it will
; overwrite the old one automatically) It shows the path the path C:\Program Files\LocaleDlls
InstallDirRegKey HKLM "Software\NSIS_LocaleDlls" "Install_Dir"

; Request application privileges for Windows Vista

您不需要致电GetUserDefaultUILanguage，NSIS会致电GetUserDefaultUILanguage来尝试设置默认的$language。如果找不到匹配的语言，则使用.NSI中指定的第一种语言。所有这些都在调用.onInit之前发生，您无需执行任何操作。但是，如果您对NSIS选择的语言不满意，可以在$language中更改.onInit。您还可以使用!insertmacro MUI_LANGDLL_DISPLAY显示语言选择对话框。

使用MUI时，需要在语言之前插入页面，因为语言宏需要知道页面需要哪些字符串。使用MUI页面宏MUI_PAGE_ *而不是本机页面很重要：

!insertmacro MUI_PAGE_WELCOME
Page Custom MyPage ; There is no MUI_PAGE_* macro for this
!insertmacro MUI_PAGE_COMPONENTS
!insertmacro MUI_PAGE_INSTFILES

!insertmacro MUI_LANGUAGE "English" ; Must come after all MUI_PAGE_* macros.

如何基于语言环境加载文件并使用NSIS生成安装程序？
