PacketX doesn't work in Beta 3.3.7.21, it's ok in 3.3.5.6

[frank10]

I have a sniffing script that uses PacketX with Winpcap in W7.

Const $PktXPacketTypePromiscuous = 0x0020
Const $PktXModeCapture = 1
; # CREATE PACKETX OBJECT #  
Global $oPktX = ObjCreate("PktX.PacketX")
If Not IsObj($oPktX) Then
MsgBox(48, "Error", "PacketX could not load the object, reinstall!")
Else
$EventObject = ObjEvent($oPktX, "PacketX_")
EndIf
; # GET THE DEVICE NUMBERS #
$deviceno = ""
$deviceitem = ""
For $i = 1 To $oPktX.Adapters.Count
If $oPktX.Adapters($i).IsGood Then
  $deviceitem = $i
  $deviceno = $deviceitem & "|" & $deviceno
Else
  MsgBox(48, "Error", "No Valid Network Adaptors was found!")
EndIf
Next
$oPktX.Adapter = $oPktX.Adapters(2)

with official autoit 3.3.5.6 works well, but if I use the beta 3.3.7.21, the same script from Scite says cannot make that operation with this object:

$oPktX.Adapter = $oPktX.Adapters(2)

What's this?

Does it work with the latest production version 3.3.6.1?

[frank10]

I tried 3.3.6.1, yes it works, it's only with Beta that doesn't work.

Do you have a COM error handler in your script?

[frank10]

Before of that call to PacketX in my script I call Sqlite, some stdoutRead-Err call and this line:

local $a = _CommSetPort($CMPort, $sportSetError, $CmBoBaud, $CmboDataBits, $CmBoParity, $CmBoStop, $setflow, $RTSMode, $DTRMode)

of CommMG.au3 to initialize a serial port.

I think I don't have COM error handler before calling PacketX.

Could you please insert the following code:

$oMyError = ObjEvent("AutoIt.Error","MyErrFunc") ; Initialize a COM error handler

; ... Here goes the rest of your script

; This is my custom defined error handler
Func MyErrFunc()

Msgbox(0,"AutoItCOM Test","We intercepted a COM Error !" & @CRLF & @CRLF & _
"err.description is: " & @TAB & $oMyError.description & @CRLF & _
"err.windescription:" & @TAB & $oMyError.windescription & @CRLF & _
"err.number is: " & @TAB & hex($oMyError.number,8) & @CRLF & _
"err.lastdllerror is: " & @TAB & $oMyError.lastdllerror & @CRLF & _
"err.scriptline is: " & @TAB & $oMyError.scriptline & @CRLF & _
"err.source is: " & @TAB & $oMyError.source & @CRLF & _
"err.helpfile is: " & @TAB & $oMyError.helpfile & @CRLF & _
"err.helpcontext is: " & @TAB & $oMyError.helpcontext _
)
Endfunc

This grabs all COM errors and for each a MessageBox is shown.

[frank10]

I will try it in two or three hours.

[frank10]

The COM handler says:

description: impossible to find member (I translate it from italian 'membro')

err.numb: 80020003

lastdll: 0

Do you get the COM error on the same line as the error in your first post? Sometimes the problem is located many lines above the line crashing the script.

Did you have a look at the of the 3.3.7.21 version? COM support has changed and there might be some script breaking changes.

[frank10]

For the latest test I made a script with only that part I posted above.

So, yes the line of the error is the same:

$oPktX.Adapter = $oPktX.Adapters(2)

and there are no other things except call to PacketX

Then I think it's time to ask one of the Devs.

Or install one of the older 3.3.7.x betas (i would start with 3.3.7.0). If it works with one of the 3.3.7.x betas you know that there might be a bug in 3.3.7.21.

[frank10]

At this point I can use the 3.3.5.6, I don't need the beta now.

It could only be useful for the devs to know there is a bug.

And in the future, if the beta will became official...
