how to display conditionally a custom page
How can I display a custom page during setup depending on a variable ?
I have a variable, which if it is true allow me to display a custom page before going on with my setup and if it is false I just want to continue without displaying my custom page.

Thx

hello,
have a look at InstallOptions.nsi in your "NSIS\Examples\Modern UI" folder. there are a few custom pages.
for example you have for the second page


CustomPageB

 !insertmacro MUI_HEADER_TEXT "$(TEXT_IO_TITLE)" "$(TEXT_IO_SUBTITLE)"

 !insertmacro MUI_INSTALLOPTIONS_DISPLAY "ioB.ini"

>FunctionEnd 

>

if you add one line, a comparation, it will not be displayed all the time, depending on your selection. the line is already used for displayng a message box if the section was selected. try it.


CustomPageB

 !insertmacro MUI_HEADER_TEXT "$(TEXT_IO_TITLE)" "$(TEXT_IO_SUBTITLE)"

 StrCmp $INI_VALUE "1" "" +2

 !insertmacro MUI_INSTALLOPTIONS_DISPLAY "ioB.ini"

>FunctionEnd 

>

have a look at StrCmp in NSIS manual.
hope it helps.
