NSIS2 + Modern UI + Control 'back' button

Hi,
I have an installer that have 3 custom pages w/ io, and i do some operations before and after and when the user clicks back, i want to do nothing after displaying.
note: i cant do before display the next custom page.
not using the modern ui i will try the next

Function CP_SetDBEngine

    ;if the section is checked continue else exit

   SectionGetFlags ${SecEnvironment} $0

   IntCmp $0 1 lbl_SetDBSetup_Continue

   Goto lbl_SetDBSetup_Exit



   lbl_SetDBSetup_Continue:



   ;some instructions

   

   installoptions::show "ioDBSetup.ini"

   Pop $0



   StrCmp $0 "success" "" lbl_SetDBSetup_Exit



   ;some instructions



   messagebox mb_ok "hey! it continues!"



   lbl_SetDBSetup_Exit:

FunctionEnd

trying with modern ui, this code always goes lbl_SetDBSetup_Exit

Function CP_SetDBEngine

    ;if the section is checked continue else exit

   SectionGetFlags ${SecEnvironment} $0

   IntCmp $0 1 lbl_SetDBSetup_Continue

   Abort

   lbl_SetDBSetup_Continue:



   ;some instructions

   

   !insertmacro MUI_INSTALLOPTIONS_DISPLAY "ioDBSetup.ini"

   Pop $0



   StrCmp $0 "success" "" lbl_SetDBSetup_Exit



   ;some instructions



   messagebox mb_ok "hey! it continues!"



   lbl_SetDBSetup_Exit:

FunctionEnd

someone knows how can i do this?
thanks & sorry about my poor english 🙄

The Modern UI macro MUI_INSTALLOPTIONS_DISPLAY "eats" the return value of InstallOptions for you. The macro only calls InstallOptions and "eats" the return value so you can use the normal InstallOptions::show.

BTW, welcome to the forums 😁

Hasta que me encuestro alguien que hable español 😛

dark_boy: y eso? a que viene?
kichik: thanks. 😁 it works with next code:

   ; some instructions

   Push $0

   InstallOptions::dialog "$PLUGINSDIR\ioDBSetup.ini"

   Pop $0

   StrCmp "$0" "success" lbl_DBSetup_Display_Success

   Abort



   lbl_DBSetup_Display_Success:

   ;next instructions
