Custom License Page - big license file
  Hello,

I am new in NSIS.

I have to add a "Save License File" button on (a custom) license page.

My problem is that if the license.txt is bigger than 1024 B, the file is displayed trimmed.

        FileOpen$0 "$INSTDIR/License.txt" r 

         StrCpy $file"" ; initialize! 

        loop: 

             FileRead $0 $2 

              IfErrors done 

              StrCpy $file "$file$2" 

              Goto loop 

         done: 

             FileClose $0 

   !insertmacro CHANGETEXTFIELD "${DIALOG1}" "${CMD_FIELD_2}" $file 

>

  !macro CHANGETEXTFIELD FILE ELEMENT VALUE

  Push $R0; holds value

 !insertmacro MUI_INSTALLOPTIONS_WRITE ${VALUE} "${FILE}" "${ELEMENT}" "State"

 !insertmacro MUI_INSTALLOPTIONS_READ $R0 "${FILE}" "${ELEMENT}" "HWND"

 SendMessage $R0 ${WM_SETTEXT} 0 "STR:${VALUE}"

  Pop $R0

 !macroend

I've tried to add a custom button on the a default License page. But if I add a custom button over the existing controls, the "old" controls disappears.

define MUI_PAGE_CUSTOMFUNCTION_PRE lic_pre

>!insertmacro MUI_PAGE_LICENSE "License.txt" 

lic_pre

 !insertmacro MUI_HEADER_TEXT "Title" "Subtitle"  

  nsDialogs::Create 1018 

        ${NSD_CreateCheckbox} 60% 90% 50% 6% "Show button below"

        Pop $hwnd

       ${NSD_OnClick} $hwnd EnDisableButton

   ${NSD_CreateButton} 25% 25% 50% 50% "Hello World"

        Pop $button

        ShowWindow $button${SW_HIDE} # start out hidden

  nsDialogs::Show 

FunctionEnd

Can you please give me a hint ...?

Search the forum for EM_STREAMIN or something like that and you should find a thread about reading large license files
