D.4 Dump Content of Log Window to File

This function will dump the log of the installer (installer details) to a file of your choice. I created this function for Afrow_UK who requested a way to dump the log to a file in this forum thread.

To use it, push a file name and call it. It will dump the log to the file specified. For example:

GetTempFileName $0

Push $0

Call DumpLog

Here is the function:

!define LVM_GETITEMCOUNT 0x1004

!define LVM_GETITEMTEXT 0x102D



Function DumpLog

  Exch $5

  Push $0

  Push $1

  Push $2

  Push $3

  Push $4

  Push $6



  FindWindow $0 "#32770" "" $HWNDPARENT

  GetDlgItem $0 $0 1016

  StrCmp $0 0 error

  FileOpen $5 $5 "w"

  StrCmp $5 0 error

    SendMessage $0 ${LVM_GETITEMCOUNT} 0 0 $6

    System::Alloc ${NSIS_MAX_STRLEN}

    Pop $3

    StrCpy $2 0

    System::Call "*(i, i, i, i, i, i, i, i, i) i \

      (0, 0, 0, 0, 0, r3, ${NSIS_MAX_STRLEN}) .r1"

    loop: StrCmp $2 $6 done

      System::Call "User32::SendMessageA(i, i, i, i) i \

        ($0, ${LVM_GETITEMTEXT}, $2, r1)"

      System::Call "*$3(&t${NSIS_MAX_STRLEN} .r4)"

      FileWrite $5 "$4$\r$\n"

      IntOp $2 $2 + 1

      Goto loop

    done:

      FileClose $5

      System::Free $1

      System::Free $3

      Goto exit

  error:

    MessageBox MB_OK error

  exit:

    Pop $6

    Pop $4

    Pop $3

    Pop $2

    Pop $1

    Pop $0

    Exch $5

FunctionEnd
