NSIS : Why "Text" from text box value became numeric?

I've created a custom page(.nsh) and there are 3 text boxes (url, user, password) for user typing in it and .NSI file will get these data to write into a properties file.

But those text became to numeric such 9502966, 4718976 and 8455398. What should I do?

This is my example code:

AcustomPage.nsh

...

!macro create_AcustomPage APP_NAME CUS_URL CUS_USER CUS_PWD
Page custom create_AcustomPage
Function create_AcustomPage
   ...
   ${NSD_CreateText} 60u 50u 60% 11u "${CUS_URL}"
   Pop $AcustomPage.url
   ${NSD_CreateText} 60u 50u 60% 11u "${CUS_USER}"
   Pop $AcustomPage.user
   ${NSD_CreateText} 60u 50u 60% 11u "${CUS_PWD}"
   Pop $AcustomPage.pwd
   ...
FunctionEnd
...
!macroend

Project.nsi

...

 !insertmacro create_AcustomPage "${NAME} ${VERSION}-${RELEASE}" "url.localhost" "username" "password"
...    
${ConfigWriteS} "$INSTDIR\configure.properties" "custom_url=" "$CUS_URL" $R0
${ConfigWriteS} "$INSTDIR\configure.properties" "custom_user=" "$CUS_USER" $R0
${ConfigWriteS} "$INSTDIR\configure.properties" "custom_password=" "$CUS_PWD" $R0

Result #configure.properties

addi_url=18940788
addi_user=6750598
addi_password=11469950

But it should be:

addi_url=usl.localhost
addi_user=username
addi_password=password

Thanks,

Solution

I'm guessing you are writing the controls handle to the file but it is impossible to know because of your poor example code.

It should probably look something like this:

InstallDir "$Temp\Test"

!include TextFunc.nsh
!include nsDialogs.nsh


var hCtlUrl
var hCtlUsr
var hCtlPwd

!define DefaultUrl "url.localhost"
!define DefaultUsr "foo"
!define DefaultPwd "bar"

Function mypageCreate
nsDialogs::Create 1018
Pop $0
${NSD_CreateText} 60u 30u 60% 11u "${DefaultUrl}"
Pop $hCtlUrl
${NSD_CreateText} 60u 50u 60% 11u "${DefaultUsr}"
Pop $hCtlUsr
${NSD_CreateText} 60u 70u 60% 11u "${DefaultPwd}"
Pop $hCtlPwd
nsDialogs::Show
FunctionEnd

Function mypageLeave
${NSD_GetText} $hCtlUrl $0
${ConfigWriteS} "$INSTDIR\configure.properties" "custom_url=" "$0" $R0
${NSD_GetText} $hCtlUsr $0
${ConfigWriteS} "$INSTDIR\configure.properties" "custom_user=" "$0" $R0
${NSD_GetText} $hCtlPwd $0
${ConfigWriteS} "$INSTDIR\configure.properties" "custom_password=" "$0" $R0
FunctionEnd
