filling passwords needed in a silent installation

[glenncarr]

Take a look at the GetOptions macro defined in FileFunc.nsh. It allows command line options like /RESPONSE=responsefile.ini. If you format it as an .ini file, you can use the ReadINIStr commands to pull information out of it, such as usernames and passwords.

In our case we simply supply a sample response.ini file, so that our user can create their own to do silent installs like this:

OurSetup.exe /S /RESPONSE=responses.ini

...where responses.ini might contain:

code:
; Global installation options

[Options]

InstallDir=C:\Program Files\MyApp

Password=password

Here's some sample script for getting the values:

code:


!include FileFunc.nsh



...



!insertmacro GetOptions



...



StrCpy $1 ""

${GetOptions} $0 "/RESPONSE=" $1



IfErrors 0 RespExists

  DetailsLogSet on

  DetailPrint "*** No response file was specified for silent installation, setup will abort."

  Abort



RespExists:

  IfFileExists $1 RespFile

    DetailsLogSet on

    DetailPrint "*** Response file specified was not found for silent installation, setup will abort."

    Abort



RespFile:

  StrCpy $RespFile $1



  ReadINIStr $0 $RespFile "Options" "InstallDir"

  StrCmp $0 "" NoDir

  StrCpy $INSTDIR $0



NoDir:

  DetailsLogSet on

  DetailPrint "Using response file $RespFile"

(You'll need to remove or replace the DetailsLogSet unless you use the build I posted about earlier, or replace it with LogSet and use LogText instead of DetailPrint.)
