Help needed on having user pass data to installer

Any help/example with this would be super-appreciated...

So I have a function that replaces, during the install, a variable called @IPADDRESS@ with an actual value (e.g. 255.255.255.0). Problem is, right now I am hardcoding the 255.255.255.0 in the function itself.

What I would love to be able to do, is to have a custom screen displayed to the user that asks for that information, stores it into a variable and then passes it to the stringreplace function i have. Below is what i am talking about. I'd like to replace that 255.255.255.0 with a variable coming from the custom screen:

Section "Update Configuration Files"
; Replace IP address with hardcoded value for config.txt
Push @IPADDRESS@ #text to be replaced
Push "255.255.255.0" #replace with
Push all #replace all occurrences
Push all #replace all occurrences
Push C:\TestInstall\ZipExample2\Config1\config.txt #file to replace in
Call AdvReplaceInFile
SectionEnd


THANKS!!!!

Hi again,

Use InstallOption (this example is for Modern UI)
*)NSIS\Contrib\InstallOptions\Readme.html
*)NSIS\Contrib\Modern UI\Readme.html


1) create ini file with description of your dialog:

[Settings]

NumFields=1



[Field 1]

Type=Text

State=255.255.255.0

Left=6

Right=130

Top=7

Bottom=20

2) in your script in .onInit section

Function .onInit

  ...

  InitPluginsDir

  SetOutPath $PLUGINSDIR

  !insertmacro MUI_INSTALLOPTIONS_EXTRACT "IniFile"

  ;optionally - change default value in $0

  !insertmacro MUI_INSTALLOPTIONS_WRITE "IniFile" "Field 1" "State" "$0"  

  ...

FunctionEnd

3) in your script among other pages

Page custom yourPage yourPageValidate

4) somewhere in your script

Function yourPage 

  ...

 !insertmacro MUI_INSTALLOPTIONS_INITDIALOG "IniFile"

  ...

 !insertmacro MUI_INSTALLOPTIONS_SHOW

  ...

FunctionEnd

5) somewhere in your script

Function yourPageValidate 

  ...

  ReadINIStr $0 "$PLUGINSDIR\IniFile" "Settings" "State"

  StrCmp $0 1  validateAddr

  Abort 

validateAddr:

   ;do some validation

   Abort

FunctionEnd

6) get the value passed by user

  !insertmacro MUI_INSTALLOPTIONS_WRITE "IniFile" "Field 1" "State" "$0"  

   MessageBox MB_OK "Value: $0"

Uff..., I hope there is no mistake ... 😉

Kobus

thanks! ill try all that

Ok, i know i sound totally clueless with this (maybe it's cause i am...).. I have the following items in my page and function sections. Yet my debug messages are not returning anything...And the custom screen is not displayed when i test the installer...

Page custom configPage "" "Configuration Options"

Function .onInit
File /oname=configPage.ini configPage.ini
FunctionEnd

Function configPage
Push $R0
InstallOptions::dialog "configPage.ini"
MessageBox MB_OK 'The ini file is called "$R0"'
Pop $R0
ReadINIStr $R1 "configPage.ini" "Field 2" "Machine"
MessageBox MB_OK 'The machine name entered was "$R1"'
Pop $R1
FunctionEnd

try this ...

Function .onInit

  InitPluginsDir

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

FunctionEnd



Function configPage

  ...

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

  ...

FunctionEnd

I've got the following, but it's not working. The first message box does return the temp location of the ini file, but the second one does not return anything for the "machine". Am i not doing the pop/push right or something?
Again, your help is v. much appreciated!


Function .onInit
File /oname=configPage.ini configPage.ini
FunctionEnd

Function configurationPage
GetTempFileName $R0
File /oname=$R0 configPage.ini
InstallOptions::dialog $R0
MessageBox MB_OK 'The ini file is called "$R0"'
ReadINIStr $0 "configPage.ini" "Field 2" "Machine"
MessageBox MB_OK 'Machine name is:"$0"'

FunctionEnd

change
ReadINIStr $0 "configPage.ini" "Field 2" "Machine"
to
ReadINIStr $0 "configPage.ini" "Field 2" "State"

should work
Kobus

It still doesn't work. Why would State work better than Machine anyway?
I really don't see what my problem is, because i'm doing what many posts say i should do, yet it doesn't work...I'm attaching my nsi file, maybe you could take a look at it:

attach your configPage.ini also ...

this work for me ..., (I've generated some ini file with 3 text fields for testing 🙂 )

Function .onInit

 ;set output path - in here all files from now goes to user temporary directory

 SetOutPath $TEMP

 ;extract configPage.ini to user temporary directory

 File configPage.ini

FunctionEnd



Function configurationPage

 InstallOptions::dialog $TEMP\configPage.ini

 MessageBox MB_OK 'The ini file is  called "$TEMP\configPage.ini"'

 ;There is nothing like "Machine" value in configPage.ini

 ;value of the field is stored in State

 ReadINIStr $0 "$TEMP\configPage.ini" "Field 3" "State"

 MessageBox MB_OK 'Machine name is:"$0"'

FunctionEnd

This is my ini file:
