How to use InstallOptions?

Hello,

I tried the last three days to find the solution,
but I couldn't managed it.

I will use a custom finish page for the classic installer.

I have used follow ini file (finish_page.ini):



[Settings]

NumFields=3



[Field 1]

Type=GroupBox

Left=0

Right=-1

Top=0

Bottom=-5

Text=Installation Complete



[Field 2]

Type=checkbox

Text=Create a shortcut on your desktop?

Left=10

Right=-10

Top=17

Bottom=25

State=1

Flags=GROUP



[Field 3]

Type=checkbox

Text=Launch MyApp!

Left=10

Right=-10

Top=43

Bottom=51

State=1

Flags=GROUP

and this working InstallOption page:



!define TEMP1 $R0 ;Temp variable



;The name of the installer

Name "MyApp"



;The file to write

OutFile "MyApp.exe"

InstallDir "$PROGRAMFILES\MyApp"

; Show install details

ShowInstDetails show



;Things that need to be extracted on startup

;Only useful for BZIP2 compression

;Use ReserveFile for your own InstallOptions INI files too!



ReserveFile "${NSISDIR}\Plugins\InstallOptions.dll"

ReserveFile "finish_page.ini"



;Order of pages

;Custom page. InstallOptions gets called in SetCustom.

Page custom SetCustom ValidateCustom ": Finish Page" 

Page instfiles



Section "Finish_page"

  ;Get Install Options dialog user input



  ReadINIStr ${TEMP1} "$PLUGINSDIR\finish_page.ini" "Field 2" "State"

  DetailPrint "Create Shortcut=${TEMP1}"

  

  ReadINIStr ${TEMP1} "$PLUGINSDIR\finish_page.ini" "Field 3" "State"

  DetailPrint "Start Game=${TEMP1}"

SectionEnd



Function .onInit

  ;Extract InstallOptions files

  ;$PLUGINSDIR will automatically be removed when the installer closes

  

  InitPluginsDir

  File /oname=$PLUGINSDIR\finish_page.ini "finish_page.ini"

  

FunctionEnd



Function SetCustom

  ;Display the InstallOptions dialog



  Push ${TEMP1}



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

    Pop ${TEMP1}

  

  Pop ${TEMP1}



FunctionEnd



Function ValidateCustom



  ReadINIStr ${TEMP1} "$PLUGINSDIR\finish_page.ini" "Field 2" "State"

  StrCmp ${TEMP1} 1 done

  ReadINIStr ${TEMP1} "$PLUGINSDIR\finish_page.ini" "Field 3" "State"

  StrCmp ${TEMP1} 1 done



  done:

 

FunctionEnd

Please can somebody add the script for the "Creating DesktopShortcut" and "Launching App"?
I doesn't understand the recognition of the used checkbox and the needed function for the checkbox.

I think for a profi it couldn't be difficult and perhaps you take a minute to help me.

Thank you! and best regards.

You need to compare the ${TEMP1} variable values with 1 (for selected).

E.g.

Function ValidateCustom

Push ${TEMP1}



## Create shortcut

ReadINIStr ${TEMP1} "$PLUGINSDIR\finish_page.ini" "Field 2" "State"

StrCmp ${TEMP1} 1 0 +2

 CreateShortcut ...



## Launch program

ReadINIStr ${TEMP1} "$PLUGINSDIR\finish_page.ini" "Field 3" "State"

StrCmp ${TEMP1} 1 0 +2

 Exec ...



Pop ${TEMP1}

FunctionEnd

Hi Afrow UK,

thank you for your help and for the correction of your
script, because first I add your script to this Section:



Section "Finish_page"

  ;Get Install Options dialog user input



  ReadINIStr ${TEMP1} "$PLUGINSDIR\finish_page.ini" "Field 2" "State"

  DetailPrint "Create Shortcut=${TEMP1}"

  ## Create shortcut

StrCmp ${TEMP1} 1 0 +2

 CreateShortcut ...

.

.

.

This works, but I have forgot that I would create a finish page with this options.
So I have change the order of the page list.

;Order of pages
Page instfiles
;Custom page. InstallOptions gets called in SetCustom.
Page custom SetCustom ValidateCustom ": Finish Page"
...

-> the result, all files and the options are installed
before I could make a choice!

After your correction I used your script in the "Function ValidateCustom" Section and this is really better.
🙂

Now, I have only one question. In the detail list of the installer I always see that the options are choiced before the finishpage.

The reason is this, I think:



Section "Finish_page"

  ;Get Install Options dialog user input



  ReadINIStr ${TEMP1} "$PLUGINSDIR\finish_page.ini" "Field 2" "State"

  DetailPrint "Create Shortcut=${TEMP1}"

  

  ReadINIStr ${TEMP1} "$PLUGINSDIR\finish_page.ini" "Field 3" "State"

    DetailPrint "Start Game=${TEMP1}"

SectionEnd

Can you tell me how I can correct this?

@Hello Lobo Lunar! Sorry, that I have not the time to
test your script. It is a bittle late, but I will test it tomorrow.

Thanks also for your help.

Good Night!

Sections are executed only on the Instfiles page, before your Custom page. Therefore, how can it see what your user has selected before they have selected it?

Why don't you just delete the whole "Finish_page" Section, as it isn't necessary.

Hello Afrow UK and Lobo Lunar,

thanks for your help. The script works now very fine
with all options and the wanted look.

@Lobo Lunar, with your script I have one problem.
If I choice "Launch MyApp! the app will run before it is installed!

io.ini



[Settings]

NumFields=3



[Field 1]

Type=GroupBox

Left=0

Right=-1

Top=0

Bottom=-5

Text=Installation Complete



[Field 2]

Type=checkbox

Text=Create a shortcut on your desktop?

Left=10

Right=-10

Top=17

Bottom=25

State=0



[Field 3]

Type=checkbox

Text=Launch MyApp!

Left=10

Right=-10

Top=43

Bottom=51

State=0

example.nsi



BesterSetCompressor lzma

XPStyle on



Name "MyApp"

OutFile "MyApp.exe"

InstallDir "$PROGRAMFILES\MyApp"

ShowInstDetails show



Page custom "my_own_page" "" ": This is my own page"

Page instfiles "" "inst_show" ""



Var HWND



Function .onInit

InitPluginsDir

File /oname=$PLUGINSDIR\io.ini "io.ini"

FunctionEnd



Function my_own_page

Push $HWND

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

Pop $HWND

FunctionEnd



Function inst_show

ReadINIStr $0 "$PLUGINSDIR\io.ini" "Field 2" "State"

StrCmp $0 1 lnk next

next:

ReadINIStr $1 "$PLUGINSDIR\io.ini" "Field 3" "State"

StrCmp $1 1 runme exit



lnk:

DetailPrint "I'm creating a  shortcut"

CreateShortCut "$DESKTOP\MyApp.lnk" "$INSTDIR\MyApp.exe"

Goto next



runme:

DetailPrint "I'm running my self"

Exec "$INSTDIR\MyApp.exe"

Goto exit



exit:

FunctionEnd



Section -default

; Set Section properties

	SetOverwrite on



	; Set Section Files and Shortcuts

	SetOutPath "$INSTDIR\"

	File "C:\Source\MyApp\MyApp.exe"

SectionEnd

Only for fun I don't need it any more!

Best regards!

You'd have to put that code to run MyApp in a Section with no name (Section "") after all of your sections.
