Problem with _GUICtrlRichEdit_StreamFromFile = 3.3.14.0

[mLipok]

Today I get an issue with _GUICtrlRichEdit_StreamFromFile  function.

 

#include <GUIConstantsEx.au3>
#include <GuiRichEdit.au3>
#include <WindowsConstants.au3>

Example()

Func Example()
    Local $hGui, $iMsg, $idBtnNext, $iStep = 0, $idLblMsg, $hRichEdit
    $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, StringLen(".exe")) & ")", 320, 350, -1, -1)
    $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, _
            BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    $idLblMsg = GUICtrlCreateLabel("", 10, 235, 300, 60)
    $idBtnNext = GUICtrlCreateButton("Next", 270, 310, 40, 30)
    GUISetState(@SW_SHOW)

    _GUICtrlRichEdit_StreamFromFile($hRichEdit, @ScriptDir & "\wzor.rtf")
    While True
        $iMsg = GUIGetMsg()
        Select
            Case $iMsg = $GUI_EVENT_CLOSE
                _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
                ; GUIDelete()   ; is OK too
                Exit
        EndSelect
    WEnd
EndFunc   ;==>Example

as this function load my RTF file as:

??????????????????????????????????????????????????????????????4????????????????????‰??????

 

When I made some further test with:
 

MsgBox(0, '', FileGetEncoding(@scriptdir & '\wzor.rtf'))

Then I get 1024 == $FO_UTF16_LE_NOBOM (1024) = Use Unicode UTF16 Little Endian (without BOM) reading and writing mode.
 

So I look inside

_GUICtrlRichEdit_StreamFromFile()

Then I must change this:

$hFile = FileOpen($sFileSpec, $FO_READ )

to

$hFile = FileOpen($sFileSpec, $FO_READ  + $FO_UTF8 )

 

And it start to works correctly (in my case).

Amended title

mLipok,

How about a less dramatic title? I expect better from someone with your experience.

That's odd: if the file encoding is indeed UTF16-LE, why open it in UTF8 mode? And how can this mode work at all in this case?

Looks like there's another glitch in either FileGetEncoding or FileOpen.

I guess it could be changes that Jon made to FileOpen().

[jchd]

Maybe he reused code parts from IPB v4.*

Excuse Me.
I realize that sometimes I'm too few diplomatic.

 

EDIT:
But as you remember I used a Question Mark in my thread title.

EDIT2:
I promise to pay more attention to the way of expression.

mLipok,

How did you save the file you tried to read? When I save the file from within the script, clear the RichEdit and then re-read the file it works without problem:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiRichEdit.au3>

$sFile = @ScriptDir & "\Test.rtf"

$hGui = GUICreate("Test", 500, 500)
$hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test to show mLipok that it works and there is no bug.", 10, 10, 480, 300, BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
$cSave = GUICtrlCreateButton("Save", 10, 460, 80, 30)
$cRead = GUICtrlCreateButton("Read", 150, 460, 80, 30)
GUICtrlSetState($cRead, $GUI_DISABLE)

GUISetState(@SW_SHOW)

While 1
    Switch GUIGetMsg()
        Case $cSave

            _GUICtrlRichEdit_StreamToFile($hRichEdit, $sFile)
            _GUICtrlRichEdit_SetSel($hRichEdit, 0, -1)
            _GUICtrlRichEdit_ReplaceText($hRichEdit, "")
            GUICtrlSetState($cRead, $GUI_ENABLE)
        Case $cRead

            _GUICtrlRichEdit_StreamFromFile($hRichEdit, $sFile)
        Case $GUI_EVENT_CLOSE
            _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
            Exit
    EndSwitch
WEnd

It was long time age when I create this file.
It was made by Copy Paste from some other app (old TxTextcontrol embended in some CRM system) to Wordpad .

 

[Jon]

rtf files are only supposed to contain ASCII 0-127 characters AFAIK. It would only be detected as UTF16 if it contained a BOM at the start. It should be plain ascii with no BOM so the file sounds broken.

[mLipok]

hmm...

I made further test.

First I open WordPad and made  test.rtf (EDIT: I just type some Polish diacratic characters to the empty document and save them)

After that I make this following testing script:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <GuiRichEdit.au3>
#include <WindowsConstants.au3>

Example()

Func Example()
    Local $hGui, $iMsg, $idBtnNext, $iStep = 0, $idLblMsg, $hRichEdit
    $hGui = GUICreate("Example (" & StringTrimRight(@ScriptName, StringLen(".exe")) & ")", 320, 350, -1, -1)
    $hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is a test.", 10, 10, 300, 220, _
            BitOR($ES_MULTILINE, $WS_VSCROLL, $ES_AUTOVSCROLL))
    $idLblMsg = GUICtrlCreateLabel("", 10, 235, 300, 60)
    $idBtnNext = GUICtrlCreateButton("Next", 270, 310, 40, 30)
    GUISetState(@SW_SHOW)

    Local $sRTF_FileFullPath = @ScriptDir & "\test.rtf"
    MsgBox(0, '', FileGetEncoding($sRTF_FileFullPath))
    _GUICtrlRichEdit_StreamFromFile($hRichEdit, $sRTF_FileFullPath)
    While True
        $iMsg = GUIGetMsg()
        Select
            Case $iMsg = $GUI_EVENT_CLOSE
                ExitLoop
        EndSelect
    WEnd


;~  Local $hFile = FileOpen($sRTF_FileFullPath, $fo_READ + $FO_UTF8)
    Local $hFile = FileOpen($sRTF_FileFullPath, $fo_READ + $FO_UTF8_NOBOM )
    Local $sRTFContent = FileRead($hFile)
    FileClose($hFile)
    MsgBox(0, '', $sRTFContent)

    _GUICtrlRichEdit_StreamFromVar($hRichEdit, $sRTFContent)
    While True
        $iMsg = GUIGetMsg()
        Select
            Case $iMsg = $GUI_EVENT_CLOSE
                _GUICtrlRichEdit_Destroy($hRichEdit) ; needed unless script crashes
                ; GUIDelete()   ; is OK too
                ExitLoop
        EndSelect
    WEnd

EndFunc   ;==>Example

 

As you can see 

MsgBox(0, '', FileGetEncoding($sRTF_FileFullPath))

is recognized as $FO_BINARY (16)

Sublime Text opens that as binary as well. It's because it has a null at the end of it I think.

If that UDF is always designed to read just rtf files it probably needs a similar modification from the first post to ensure it reads in UTF8_NOBOM
