为什么当我添加自定义 nsDialog 页面时，我的 NSIS 脚本似乎跳过了 MUI_PAGE_INSTFILES 等安装页面？答案

【问题标题】：Why does my NSIS script appear to be skipping over installation pages like MUI_PAGE_INSTFILES when I add custom nsDialog pages?为什么当我添加自定义 nsDialog 页面时，我的 NSIS 脚本似乎跳过了 MUI_PAGE_INSTFILES 等安装页面？

【问题描述】：

这是我最新的 NSIS 安装脚本，它已经成长为一个野兽。

我的问题是，如何将 HW_DATA_DIR、HW_WORKSPACE_DIR 和可能的 %HEADWAVE_ROOT_DIR% 的所有部分放在一个页面中？我猜我必须以某种方式使用nsDialog。我的主管希望我这样做，因为有很多单独的安装页面，您必须不断点击并点击太多次才能完成安装。

我尝试了以下方法，但在函数中添加 nsDialog 就像 Page custom HeadwaveConfiguration 所做的那样似乎不太适合程序流程。这是我的代码修改：

Var headwaveConfigDialog
Var headwaveConfigDataDirLabel
Var headwaveConfigDataDirText
Var headwaveConfigWkDirLabel
Var headwaveConfigWkDirText

!define MUI_PAGE_CUSTOMFUNCTION_PRE SelectFilesCheck
!define MUI_PAGE_CUSTOMFUNCTION_LEAVE ComponentsLeave
!insertmacro MUI_PAGE_COMPONENTS

## This is the title on the Headwave Data Directory page
;!define MUI_DIRECTORYPAGE_TEXT_TOP "$(MUI_DIRECTORYPAGE_TEXT_TOP_HW)"
;!define MUI_PAGE_HEADER_TEXT "Headwave configuration"
; !define MUI_PAGE_HEADER_SUBTEXT "Select the folder which Headwave can use as a data storage."
Page custom HeadwaveConfiguration

; ; HW Data 
; !define MUI_PAGE_CUSTOMFUNCTION_PRE hw_data_pre
; !define MUI_PAGE_CUSTOMFUNCTION_SHOW hw_data_dir
; !define MUI_DIRECTORYPAGE_VARIABLE $HW_DATA_DIR
; !insertmacro MUI_PAGE_DIRECTORY

; ## This is the title on the Headwave Workspace Directory page
; !define MUI_DIRECTORYPAGE_TEXT_TOP "$(MUI_DIRECTORYPAGE_TEXT_TOP_HW_WK)"
; !define MUI_PAGE_HEADER_TEXT "Choose Headwave Workspace directory"
; !define MUI_PAGE_HEADER_SUBTEXT "Select the folder which Headwave can use as a workspace."

; # HW Workspaces
; !define MUI_PAGE_CUSTOMFUNCTION_PRE hw_wk_pre
; !define MUI_PAGE_CUSTOMFUNCTION_SHOW hw_wk_dir 
; !define MUI_DIRECTORYPAGE_VARIABLE $HW_WORKSPACE_DIR
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro MUI_PAGE_INSTFILES    
 
## This is the title on the Headwave installation Directory page to obtain directory for %HEADWAVE_ROOT_DIR
!define MUI_DIRECTORYPAGE_TEXT_TOP "$(MUI_DIRECTORYPAGE_TEXT_TOP_HW_INST)"
!define MUI_PAGE_HEADER_TEXT "Choose Headwave Plugin installation directory"
!define MUI_PAGE_HEADER_SUBTEXT "Select the folder where Headwave is presently installed to set environment variable."
 
!define MUI_PAGE_CUSTOMFUNCTION_PRE SelectFilesHeadwaveProg
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro MUI_PAGE_INSTFILES

; ...

Function HeadwaveConfiguration
  !insertmacro MUI_HEADER_TEXT "Headwave configuration" "Select the respective folders for Headwave."
  nsDialogs::Create 1018
  Pop $headwaveConfigDialog

  ${NSD_CreateLabel} 0 0 100% 12u "Select the folder which Headwave can use as a data storage:"
  Pop $headwaveConfigDataDirLabel
       
  ${NSD_CreateText} 10% 20u 80% 12u "C:\HW-Data"
  Pop $headwaveConfigDataDirText
  StrCpy $HW_DATA_DIR $headwaveConfigDataDirText   
  
  ${NSD_CreateLabel} 0 40u 80% 12u "Select the folder which Headwave can use as a workspace:"
  Pop $headwaveConfigWkDirLabel

  ${NSD_CreateText} 10% 60u 80% 12u "C:\HW-Workspaces"
  Pop $headwaveConfigWkDirText
  StrCpy $HW_WORKSPACE_DIR $headwaveConfigWkDirText        

  ;${NSD_CreateLabel} 0 80u 80% 12u "Select the folder where Headwave is installed:"
  ;Pop $headwaveConfigProgramDirLabel

  ;StrCpy $headwaveConfigProgramDirText $HeadwaveInstallDir
  ;${NSD_CreateText} 10% 100u 80% 12u $HeadwaveInstallDir
  ;Pop $headwaveConfigProgramDirText
  ;StrCpy $HeadwaveInstallDir $headwaveConfigProgramDirText           

  ;MessageBox MB_OK 'HeadwaveConfiguration: HeadwaveInstallDir = $HeadwaveInstallDir; headwaveConfigProgramDirText = $headwaveConfigProgramDirText'

  SetCtlColors $headwaveConfigHwnd 0xFF0000 0xFFFFFF
  
  nsDialogs::Show        
FunctionEnd

但问题是HeadwaveConfiguration nsDialog 页面被调用以获取HW_DATA_DIR 和HW_WORKSPACE_DIR，但随后它只是跳转开始安装MyApp，而不是先安装 Headwave 组件然后继续安装MyApp

有人有什么建议吗？ TIA。

更新：

这是我更新代码的方式，但在跳转到 MyApp 安装页面之前它仍然没有安装 Headwave 组件：

!define MUI_PAGE_CUSTOMFUNCTION_PRE SelectFilesCheck
!define MUI_PAGE_CUSTOMFUNCTION_LEAVE ComponentsLeave
!insertmacro MUI_PAGE_COMPONENTS

!define MUI_DIRECTORYPAGE_TEXT_TOP "$(MUI_DIRECTORYPAGE_TEXT_TOP_HW)"
!define MUI_PAGE_HEADER_TEXT "Headwave configuration"

!define MUI_PAGE_CUSTOMFUNCTION_SHOW HeadwaveConfigurationShow
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro MUI_PAGE_INSTFILES

我会认为应该首先调用 HeadwaveConfigurationPre 以便 $HW_DATA_DIR 应该是 C:\HW-Data 但我添加的消息框之一显示了这一点：

Headwave Plugin #2: HW_DATA_DIR = 6494062

更新 2：

感谢@Anders 的反馈。

这是我最新的代码，最初它获取$HwDataDir 和$HwWorkspaceDir 的值：

https://pastebin.com/VsT0MJf1 注意：我之前只在https://pastebin.com/DJTLQ05D中粘贴了部分代码

这是一个对话框，显示最初获取的值：

接下来进入插件安装页面：

但最终，它到达了这行代码：

MessageBox MB_OK 'Headwave Plugin #2: HwDataDir = $HwDataDir'

在这种情况下，$HwDataDir 又有一个数字：

你能告诉我，这是怎么发生的吗？为什么值会从 C:\HW-Data 变为 1181026？ TIA。

【问题讨论】：

我已经告诉过你这个数字是从哪里来的，它是nsDialogs文本控制句柄。您发布的代码甚至不包含 HeadwaveConfiguration 页面功能。请尽量减少与问题无关的代码量。 !define MUI_PAGE_CUSTOMFUNCTION_PRE SelectFilesHeadwaveProg 显然是错误的或在错误的地方等。
抱歉，我在将其放入 pastebin 时遗漏了一些代码。请立即查看pastebin.com/VsT0MJf1。根据您的解释，在我看来，代码${NSD_CreateText} 10% 20u 80% 12u "C:\HW-Data" 和Pop $headwaveConfigDataDirText 中的$headwaveConfigDataDirText 应该有数字句柄。我认为Function HeadwaveConfigurationLeave 中的$HwDataDir 与Section "Headwave Plugin" SEC1 中的$HwDataDir 有所不同
请注意，我再次更新了pastebin.com/VsT0MJf1 中的代码，所以它可以编译。现在我收到了这个警告，这对我来说没有意义，因为HwDataDir 在脚本中的多个位置使用：6001: Variable "HwDataDir" not referenced or never set, wasting memory! 你有什么建议吗？ TIA。
你永远不会写信给它。你甚至没有看我回答中的编辑吗？

标签： nsis

【解决方案1】：

您不能将 MUI_PAGE_CUSTOMFUNCTION_* 与 nsDialogs 一起使用。在您上次更新 $HwDataDir 包含一个数字，因为它是文本控件的句柄，而不是它的文本。即使您要求它的文本也是错误的时间，您应该在离开回调中这样做。自定义页面只有 create 和 leave 回调，没有 pre 和 show！

这是来自 nsDialogs 文档的示例代码的一部分：

Page custom nsDialogsPage nsDialogsPageLeave
Page instfiles

Function nsDialogsPage

    nsDialogs::Create 1018
    Pop $Dialog

    ${If} $Dialog == error
        Abort
    ${EndIf}

    ${NSD_CreateLabel} 0 0 100% 12u "Hello, welcome to nsDialogs!"
    Pop $Label

    ${NSD_CreateText} 0 13u 100% -13u "Type something here..."
    Pop $Text

    nsDialogs::Show

FunctionEnd

Function nsDialogsPageLeave

    ${NSD_GetText} $Text $0
    MessageBox MB_OK "You typed:$\n$\n$0"

FunctionEnd

您的代码包含其他问题，例如

Section "MyPartnerApp Plugin" SEC1
  ${If} ${SectionIsSelected} ${SEC1}

这没有意义，你不能这样检查自己。 IsPROG0HwDataSelected 函数已损坏，您应该使用 ${If} 和适当的节索引从头开始重写它。

更新 2：

在您的新代码中，StrCpy $HwDataDir $headwaveConfigDataDirText 是句柄“损坏”的地方。你不需要StrCpy，你只需要在leave函数中是${NSD_GetText} $headwaveConfigDataDirText $HwDataDir。
