but it do not work with Xbase++ ...

Dear Jim

 >>
  dataWriter:write(Stream)
 >>

I dont know, but Maybe

if dataWriter:write(Stream) > 0
    success
else
    not success
endif

or ...

dataWriter:write(Stream)
dataWriter:closesession(Stream)

Maybe

Regards
Osvaldo

hi,

> I dont know, but Maybe

i did not come to that Place. it is 1st Line with CreateObject() which 
"fail"
i can not access it via CreateObject(), AutomationObject() or 
XbpActiveXControl()

1.) and 2.) give NIL while 3.) crash ...
as i say , try VbScript and you will see that CLSID etc. is ok and work, but 
Xbase++ fail.

it also work with WinDEV and "other" Compiler, so it is Xbase++.

i always say, that Xbase++ v1.9x activeX is not "complett".
ImAPI show again that only 50% of activeX can be used by Xbase++

WHEN will Alaska fix it and give us "real" activeX Power for Xbase++

> but it do not work with Xbase++ ... 

with Xbase++ Add-on YUKON ( 
http://www.knowlexbase.com/en/software/downloads/yukon/index.html )
i can access IMAPI with this Code

*** Code ***
#include "yukonCDB.ch"

PROCEDURE Main
   LOCAL aDir    := Directory( "*.prg" )
   LOCAL i, imax := Len( aDir )
   LOCAL oCdBurner, oDisc, aDevices

   oCdBurner := CdBurner():new( CD_DATA )  vs CD_AUDIO
   oCdBurner:create()

    get available CD burning devices
   aDevices := oCdBurner:listDevices()

   IF Empty( aDevices )
      ? "No CD burning device available"
      oCdBurner:destroy()
      QUIT
   ENDIF

    select/activate a device
   ? "Selecting:", aDevices[1]
   oCdBurner:selectDevice( aDevices[1] )

   IF oCdBurner:isDisc() <> 1
      ? "No CD in CD drive"
      oCdBurner:destroy()
      QUIT
   ENDIF

    assign your callback code blocks
   oCdBurner:onAddProgress   := {|o,x,y| QOut("onAddProgress  ",x,y) }
   oCdBurner:onBlockProgress := {|o,x,y| QOut("onBlockProgress",x,y) }
   oCdBurner:onBurnComplete  := {|o,x  | QOut("onBurnComplete ",x)   }
   oCdBurner:onClosingDisc   := {|o,x  | QOut("onClosingDisc  ",x)   }
   oCdBurner:onEraseComplete := {|o,x  | QOut("onEraseComplete",x)   }
   oCdBurner:onPnPActivity   := {|o    | QOut("onPnPActivity  ")     }
   oCdBurner:onPreparingBurn := {|o,x  | QOut("onPreparingBurn",x)   }
   oCdBurner:onQueryCancel   := {|o    | QOut("onQueryCancel  "),.F. }
   oCdBurner:onTrackProgress := {|o,x,y| QOut("onTrackProgress",x,y) }

    get the CD Disc object that receives files to burn
   oDisc := oCdBurner:getDisc()

    add all files to the staging area
   AEval( aDir, {|a| oDisc:addFile( a[1] ) } )

    Burn to CD.
    Burning progress is reported via callback code blocks
   oCdBurner:recordDisc( .T. )   .F. == simulate burn
                                 .T. == burn CD

    Burning can be interrupted via  the :onQueryCancel callback

    Finished
   oCdBurner:ejectDisc()
   oCdBurner:destroy()

RETURN
*** Eof ***

so if a Add-on can do it,  why Xbase++ can not do it "pure" with it´s 
ActiveX Class ???
