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？

Question

Here is my latest NSIS installation script, which has grown into quite a beast.

https://pastebin.com/eSABLLsi

My question is, how can I put all of the sections for HW_DATA_DIR , HW_WORKSPACE_DIR , and possibly %HEADWAVE_ROOT_DIR% into a single page? I am guessing that I would have to use nsDialog somehow. My supervisor wants me to do this because there are so many separate install pages where you have to keep clicking and clicking too many times to complete the installation.

I have tried the following, but adding an nsDialog as Page custom HeadwaveConfiguration does in a function does not seem to fit well within the program flow. Here are my code modifications:

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

;!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."

; ...

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

  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

But the problem is that it the HeadwaveConfiguration nsDialog page gets calls to obtain HW_DATA_DIR and HW_WORKSPACE_DIR , but then it just jumps to start installing MyApp instead of first installing the Headwave components and then moving on to install MyApp

Does anyone have any suggestions? TIA.

UPDATE:

Here is how I have updated the code, but it still does not install the Headwave components before it jumps to the MyApp install page:

!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_CUSTOMFUNCTION_PRE HeadwaveConfigurationPre
!define MUI_PAGE_CUSTOMFUNCTION_SHOW HeadwaveConfigurationShow
!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)"

I would have thought since HeadwaveConfigurationPre should be called first so that $HW_DATA_DIR should be C:\HW-Data but instead one of the messageboxes I added shows this:

Headwave Plugin #2: HW_DATA_DIR = 6494062

UPDATE 2:

Thanks for the feedback, @Anders.

Here is my latest code, where initially it is getting the values for $HwDataDir and $HwWorkspaceDir :

https://pastebin.com/VsT0MJf1 NOTE: I previously pasted only partial code in https://pastebin.com/DJTLQ05D

Here is a dialog box that shows the values are being obtained initially:

Next it gets to the plugin installation page:

But then eventually, it gets to this line of code:

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

In which case the $HwDataDir has a number again:

Could you please tell me, how could that happen? Why would the value change from C:\HW-Data to 1181026? TIA.

Answer 1

You cannot use MUI_PAGE_CUSTOMFUNCTION_* with nsDialogs. In your last update $HwDataDir contains a number because it is the handle to the text control, not its text. Even if you asked for its text it would be the wrong time, you should do that in the leave callback. Custom pages only have create and leave callbacks, not pre and show!

Here is part of the example code from the nsDialogs documentation:

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

Your code contains other issues like

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

which makes no sense, you can't check itself like that. The IsPROG0HwDataSelected function is so broken you should rewrite it from scratch with ${If} and a proper section index.

Update 2:

In your new code, StrCpy $HwDataDir $headwaveConfigDataDirText is where it gets "corrupted" with the handle. You don't need StrCpy, all you need in the leave function is ${NSD_GetText} $headwaveConfigDataDirText $HwDataDir .
