crash at shockwave

[Tonigs, Nils]

Hi Ruslan,
Hi Kirill,

i use v4md 4.2 for windows with director 10.1 and valentina office server 4.2.

now, it seems that I have the same problem I had posted on 16.06.09, but this time at shockwave:

the statement getMedia() crash the browser with the alert:

"Die Anweisung in '0x6805a74d' verweist auf Speicher in '0x839ae850'. Der Vorgang 'written' konnte nicht auf dem Speicher durchgeführt werden."
(The instruction in ' 0x6805a74d' refers to memory in ' 0x839ae850'. The procedure 'written' could not be accomplished on the memory)

If field of other types than BLOB are used, no error appears.

And here the lingo-script that causes the crash:

          end repeat
          
      end case
..."

And here my additionale description:

This script-segment will fill the fieldcontent of the VCusor-object (global variable) into a proplist called 'l_aoh_objectData' and is located in repeat-loop (not shown) the work with different sql-statements.
In case of a empty VCusor the proplist 'l_aoh_objectData' is prefilled with defaultvalues.
The exeption is the field 'binary_media' (type BLOB). This value will be stored in a castmember. The proplist only hold a reference to this member.

Sorry, but at shockwave I get no logs.
The last output at the messagewindow is "NEUR darsteller für MEDIA ==> (member 73 of castLib 1)" from the line befor the getMedia().


My tests with the example-script "Remote&Local" works well, of course it use no BLOB-fields.
