NSIS Multiple components option - nsis

I am a newbie in NSIS. I need some help regarding the MUI Components page. I am adding 3 section Group and different sections inside the Section Groups. I need to do different actions based on the user selection. Users have the options to select multiple options.
So can anyone please help me with a sample code which is having more than 3 sections and verifying the user selection of those options and based on that displaying different message boxes

It is very unclear to me what your real goal is but checking section states can be done like this:
!include LogicLib.nsh
page components
page instfiles
SectionGroup /e "Group 1"
Section "G1S1" SEC_G1S1
SectionEnd
Section /o "G1S2" SEC_G1S2
SectionEnd
SectionGroupEnd
SectionGroup /e "Group 2"
Section /o "G2S1" SEC_G2S1
SectionEnd
Section "G2S2" SEC_G2S2
SectionEnd
SectionGroupEnd
Section -Hidden
${If} ${SectionIsSelected} ${SEC_G1S1}
MessageBox mb_ok "G1S1 is selected"
${EndIf}
${If} ${SectionIsSelected} ${SEC_G1S2}
MessageBox mb_ok "G1S2 is selected"
${EndIf}
# Check the other sections here ...
SectionEnd

write in header section of custom installer page (without MUI)

I used this guide to create custom page in my installer:
nsDialogs
and its working without a problem, this is the code:
!include nsDialogs.nsh
!include LogicLib.nsh
XPStyle on
Var Dialog
Page custom nsDialogsPage nsDialogsPageLeave
Function nsDialogsPage
nsDialogs::Create 1018
Pop $Dialog
${If} $Dialog == error
Abort
${EndIf}
...
nsDialogs::Show
FunctionEnd
Function nsDialogsPageLeave
...
FunctionEnd
Section
SectionEnd
But the only thing missing is this part:
Could someone help me out and show how to add text there, but without this MUI, all the guides i tried to find are refering to the MUI way but i went with Pages instead so i would like to keep it that way, surely there is a way. Thank you in advance!
Your screenshot looks like MUI. Even when using MUI, custom pages still use Page Custom ....
The MUI has a helper macro to set the text on the top for your custom pages:
!include MUI2.nsh
...
Function nsDialogsPage
!insertmacro MUI_HEADER_TEXT "Blah" "Blah blah"
nsDialogs::...
...
FunctionEnd
This macro is documented in the MUI readme. It is not in the nsDialogs documentation because these labels are in the outer dialog, not in the inner page dialog.
In the unlikely event that you are not using MUI (but you are using the MUI dialog layout and ChangeUI) you can copy the MUI_HEADER_TEXT macro from the MUI(v1) source file or write your own custom macro based on the MUI source.

How do I make only some sections readonly for a section group in NSIS?

I have a section group, and in this group I have 4 sections.
What I want: make only the first two section readonly for the group, and leave the rest optional, in the uninstall part.
My code is the following:
Function un.onInit
!insertmacro SetSectionFlag ${firstUnSec} ${SF_RO}
!insertmacro SetSectionFlag ${secondUnSec} ${SF_RO}
FunctionEnd
SectionGroup "What to delete" groupsec
Section "un.First part" firstUnSec
Call "un.DropFirst"
SectionEnd
Section "un.Second part" secondUnSec
Call "un.DropSecond"
SectionEnd
Section "un.Third part" thirdUnSec
Call "un.DropThird"
SectionEnd
Section "un.Forth part" forthUnSec
Call "un.DropForth"
SectionEnd
SectionGroupEnd
But it makes only the group readonly, and every section inside the group are optional! Why is that?
Thanks!
Code that uses the section index must come after the section itself in the .NSI file.
SectionGroup "What to delete" groupsec
Section "un.First part" firstUnSec
Call "un.DropFirst"
SectionEnd
SectionGroupEnd
Function un.onInit
!insertmacro SetSectionFlag ${firstUnSec} ${SF_RO}
FunctionEnd
You don't need any code if it's always read only, you can set the section attribute at compile-time:
SectionGroup "What to delete" groupsec
Section "un.First part" firstUnSec
SectionIn RO
Call "un.DropFirst"
SectionEnd
SectionGroupEnd

Change default buttons name NSIS

I am very new to NSIS,
I created a simple installer with 2 screens,
!include LogicLib.nsh
!include nsDialogs.nsh
Page custom someName someEndmethod
Page instfiles
First one is a custom page (nsDialogs) and on it the default button is "install" and i have 2 questtions :
How do i bound a method to its click event ?
How do i change the text on that button ?
BTW - I am not using MUI .
The best reference i could found regarding the nsDialogs was the following:
http://nsis.sourceforge.net/Docs/nsDialogs/Readme.html
but could not seem to find answer to those simple questions.
Thanks
!include WinMessages.nsh
Function MyPageCreate
GetDlgItem $0 $hwndparent 1 ; Get the handle to the button
SendMessage $0 ${WM_SETTEXT} 0 `STR:$(^NextBtn)` ; The part after STR: can be any string, using the next button language string here
nsDialogs::Create 1018
pop $0
nsDialogs::Show
FunctionEnd
Function MyPageLeave
MessageBox mb_yesno "User clicked Next/Install, allow the page change?" IDYES allow
Abort
allow:
FunctionEnd
Page Components
Page Custom MyPageCreate MyPageLeave
Page InstFiles
If you just want to change the string on the install button no matter which page it is on (The page before the instfiles page) you can change it with LangString instead.

Go back a few pages when back button pressed

I've been trying to figure out how to do that for a few days but no luck. I'm trying to go back a few pages when back button pressed during the installation.
I want to do that in the creater procedure of the page.
Page custom printerPage1 verifyPrinterFunc1 ": 1. Printer Bilgileri"
Normally I'm able to skip pages during installation by RelGotoPage Function.
Function RelGotoPage
IntCmp $R9 0 0 Move Move
StrCmp $R9 "X" 0 Move
StrCpy $R9 "3"
Move:
SendMessage $HWNDPARENT "0x408" "$R9" ""
FunctionEnd
But I can't do that in the back button pressed event (E.x. ${NSD_OnBack})
I'm stuck and need help from the experienced minds. Thank you.
!include nsDialogs.nsh
Licensedata "${__FILE__}"
InstallDir $temp
Page directory
Page components
Page license
Page custom printerPage1 verifyPrinterFunc1 ": 1. Printer Bilgileri"
Function onBack
; Go back two pages to the components page
System::Call 'USER32::PostMessage(i$HWNDPARENT,i0x408,i-2,i0)'
Abort
FunctionEnd
Function printerPage1
nsDialogs::Create 1018
Pop $0
${NSD_OnBack} onBack
nsDialogs::Show
FunctionEnd
Function verifyPrinterFunc1
FunctionEnd

Calling PRE functions of MUI in NSIS installer, skipping pages/dialogs in NSIS installer

Can PRE function of a MUI dialog be called only when required?
!define MUI_PAGE_CUSTOMFUNCTION_PRE SkipComponentsPage
!insertmacro MUI_PAGE_COMPONENTS
Function SkipComponentsPage
Abort
MessageBox MB_OK "You chose to UPDATE your current version"
FunctionEnd
//This section will be checked by default, that is , user will not be able to select or unselect this section , this has to be executed..........how to do this?To hide it , i have included a - sign in its name. its name is "mandatory"
Section "-mandatory" SEC_UPDATE
#Do update............
SectionEnd
I have two RadioButtons (Demo & Update) on my custom dialog page in the NSIS installer.
I want that when the user choses to install the UPDATE (choses the UPDATE RadioButton), then the Components Page is skipped , and a specified Section is auto CHECKED and executed.
But if the user choses to install the DEM (choses the DEMO RadioButton) , then the Components page is not skipped & the user can Check or Uncheck Sections on that Component page.
A page callback is always called, but you can put logic inside the function:
...
section "" SEC_UPDATE
sectionend
Function SkipComponentsPage
!insertmacro UnSelectSection ${SEC_UPDATE} ; Don't include update with demo by default?
${If} $InstallType == UPDATE
!insertmacro SelectSection ${SEC_UPDATE}
Abort
${EndIf}
Functionend
It is not really clear to me if you want the user to be able to choose update in the demo mode, but if you want to force the update you can make the section read only:
section "Update" SEC_UPDATE
SectionIn RO
sectionend
(And remove the UnSelectSection call from the pre function)
...or just make the section invisible with the -name prefix like you suggested.
