Silent Installer using NSIS

Hello Team,

I am overwhelmed to be part of this forum.
I am a newbie started using NSIS since Nov 2014 extensively to create a client installer for our product.

Currently i am working on converting the same installer to silent mode.
I have created a installer which accepts Login and Password as parameter.
1. I check using inetc:😛ost method and pass username and password to for existense of those accounts in my db
2. I authenticate using inetc::get method
3. I pull a certificate based on the user details using inetc::get method
4. Install the content

I use Setsilent method on Function .OnInit to test for now.

Function .onInit

MessageBox MB_YESNO|MB_ICONQUESTION "Would you like the installer to be silent from now on?" \
/SD IDYES IDNO no IDYES yes
yes:
SetSilent silent
Goto Installer
no:
SetSilent normal
Installer:

Following observations i made upon trying out silent installation.

as soon i select silent installation all inetc methods are not executing but content is dropped to expected folder.
No authentication , no certficate is getting downloaded.

Can you help me with this problem.

Thank you in advance.
Awaiting for your reply

There are no pages in silent mode. Therefore if you have any code in page callbacks, they will never execute in silent mode.

Can you suggest any other way where i can perform my operation and compatible to silent too.

You can use IfSilent or ${If} ${Silent} to perform required operations in your sections...

Hello team,

Thank you for your time and hint.
This is a code snippet which i want to make silent
Can you give me an example using the same code snippet.
This would be of great help to us.

Function Authenticate
#Call to REST API for user authentication
nsJSON::Set /file "c:\temp\<some file>"
ShowWindow $WAITMSG ${SW_SHOW}
${NSD_SetText} $WAITMSG "User authentication in progress...."

Hello team,

I request experts , Moderator, Senior Member to help me with this.

Perhaps something like this (untested):

Function Authenticate
#Call to REST API for user authentication
nsJSON::Set /file "c:\temp\<some file>"
IfSilent skipGuiStart
  ShowWindow $WAITMSG ${SW_SHOW}
  ${NSD_SetText} $WAITMSG "User authentication in progress...."
  AnimGif:lay /NOUNLOAD /HALIGN=83 /VALIGN=73 $PLUGINSDIR\a.gif
skipGuiStart:
inetc:ost "grant_type=password&username=$UserNameText&password=$UserPwdText" /SILENT "<URL>" "c:\temp\<some file>" /END
NsisCrypt::Base64Encode $UserNameText
Pop $1
#MessageBox MB_OK $1
nsJSON::Set /file "c:\temp\<some file>" /END
nsJSON::Get /exists "access_token" /END
Pop $0
${If} $0 == "yes"
nsJSON::Get "access_token" /END
Pop $TOKEN
#MessageBox MB_OK $TOKEN
StrCpy $isValidUser "true"
#Call to REST API for getting the institution details
IfSilent skipGuiSetText
  ${NSD_SetText} $WAITMSG "Getting Institution details...."
skipGuiSetText:
inetc::get /SILENT "<URL>" "c:\temp\<some file>" /END
nsJSON::Set /file "c:\temp\<some file>" /END
nsJSON::Get /count /END
Pop $INSTITUTIONCOUNT
${Else}
StrCpy $isValidUser "false"
${EndIf}
#delete "c:\temp\<some file>"
IfSilent skipGuiEnd
  ShowWindow $WAITMSG ${SW_HIDE}
  AnimGif::stop
skipGuiEnd:
