show page according to section
Hello forum.

I've created a script with several custom pages. One of them is:

Page custom UserCredentialsPage UserCreadentialsPageLeave

And several sections, one of them is:

Section "Licence"
        ...
SectionEnd

, that retrives via a webservice the licence. The problem is that, I need UserCreadenticalsPage page isn't showed if this section isn't selected.

How can I set that NSIS doesn't show my custom page if a section isn't selected?

Thanks for all.

Call abort in the page's pre-function to skip that page from being displayed - check section flags to see if the section was selected or not. Use LogicLib to make all this a lot easier.

Section "License" LicenseSectionName
...
SectionEnd

Function UserCredentialsPage
  ${Unless} ${SectionIsSelected} LicenseSectionName
    Abort
  ${EndUnless}
FunctionEnd

I've written it:

Page custom UserCredentialsPage UserPageLeave

Function UserCredentialsPage
        ${Unless} ${SectionIsSelected} LicenseSection
                Abort
        ${EndUnless}
        nsDialogs::Create /NOUNLOAD 1018
        Call setApparence
        Pop $Dialog
        
        ${If} $Dialog == error
              Abort
        ${EndIf}
        
        Call UIUser
              
        nsDialogs::Show
FunctionEnd

Function UIUser
        ${NSD_CreateLabel} 0 0 100% 12u "..."
        Call setApparence
        Pop $UserLabel

        ${NSD_CreateLabel} 15% 15% 15% 12u "Usuario: "
        Call setApparence
        Pop $UserLabel

        ${NSD_CreateText} 30% 15% 60% 12u $User
        Pop $UserText

        ${NSD_CreateLabel} 15% 30% 15% 12u "Password: "
        Call setApparence
        Pop $PasswdLabel

        ${NSD_CreatePassword} 30% 30% 60% 12u $Passwd
        Pop $PasswdText

        ${NSD_CreateLabel} 15% 45% 15% 12u "E-Mail: "
        Call setApparence
        Pop $MailLabel

        ${NSD_CreateText} 30% 45% 60% 12u $Mail
        Pop $MailText
FunctionEnd

Section "Licencia/Demo" LicenseSection
        ...
SectionEnd

But it doesn't work. After I've unselected LicenseSection, UserCreadentialsPage is showed.
What Am I do wrong?

Make sure the section is defined above your function and it should be ${LicenseSection} for your SectionIsSelected check.

darn edit limitation...

so my earlier example should have been:

; write your sections first!
; Give your sections a name that you can reference easily
Section "License" LicenseSectionName
...
SectionEnd

; and your functions later, so it can find the defined sections!
; refer to the section by name
Function UserCredentialsPage
  ${Unless} ${SectionIsSelected} ${LicenseSectionName}
    Abort
  ${EndUnless}
FunctionEnd
