Displaying files

[mstone42]

In my first foray into NSIS (and installers in general) I have almost finished my very first installer, but the last step is causing me some serious headaches. I would like to read in a file (e.g. Release Notes or Change Log) and display that as the last page of the installer. It's working (sorta), but the file is over 2K in size. Registers only hold 1K, so I'm filling registers as the file is read, but the control element on the screen also only holds 1K. I thought about using the License page, but it has that "I Agree" button on it. Any (better/alternate) ideas?

Thanks!

Here's the code so far:

code:


; ---------------------------

; header stuff here...

; ---------------------------



Page instfiles

Page custom PageReleaseNotes "" ""



; ------------------------------------------------------------------

; Reads in the Release Notes and displays at end of installtion



Var Dialog

Function PageReleaseNotes  

  nsDialogs::Create /NOUNLOAD 1018

  Pop $Dialog

  ${If} $Dialog == error

    Abort

  ${EndIf}

  

  StrCpy $R1 ""

  StrCpy $R2 ""

  

  ClearErrors

  StrCpy $R0 "Release Notes$\r$\n"

  

  StrCpy $9 0

  FileOpen $1 "$INSTDIR\icw\release_notes.txt" r

  IfErrors ReadErr

  

  ReadLoop:

    FileRead $1 $2

    IfErrors LoopErr

    

    StrLen $5 $R0

    ${If} $5 >= 1000  ;; we're about to exceed register capacity

      StrLen $5 $R1

      ${If} $5 > 0

        StrCpy $R2 $R0

      ${Else}

        StrCpy $R1 $R0

      ${EndIf}

      StrCpy $R0 ""

    ${EndIf}

    StrCpy $4 $R0

    StrCpy $R0 "$4 $\r$\n $2"

    IntOp $9 $9 + 1

      

    GoTo ReadLoop



  LoopErr:

    StrCpy $4 $R0  ; make sure we grab that last line read in

    StrCpy $R0 "$4 $\r$\n $2"

    

    FileClose $1

  ReadErr:  

  

  nsDialogs::CreateControl /NOUNLOAD ${__NSD_Text_CLASS} \

    ${DEFAULT_STYLES}|${WS_TABSTOP}|${ES_AUTOHSCROLL}|${ES_MULTILINE}|${WS_VSCROLL} \

    ${__NSD_Text_EXSTYLE} 0 0 100% 100% "$R1 $R2 $R3"

  Pop $0

  

  ; Display the dialog

  nsDialogs::Show
