hi
i am unable to create an instream object with the blob.
I am using the XmlDom Document automation.
it is giving me the error:
'This automation variable has not been instantiated .You can do it by either creating it or assigning it.'

I'm using this code:

IF NOT CREATE(XMLDoc) THEN
  ERROR('No automation');
MyRec.CALCFIELDS("XML File");
MyRec."XML File".CREATEINSTREAM(InStream);
IF NOT XMLDoc.load(InStream) THEN BEGIN
  CLEAR(XMLDoc);
  ERROR('No valid XML');
END;

How is your code or did the above help?

thanks for your reply.
The xmldom is being created however,
as i write the following code,

xmlDom.load();

the same error appears.

Actually i want to save some files in navision database and am looking for a solution.

how do you want to save the files in navision ? from the file system ? then try Field.IMPORT(<filename>) of the BLOB-Field and insert the record.

If you want to parse the content of a BLOB with a DOMDocument try this:
IF BLOBField.HASVALUE THEN BEGIN
BLOBField.CreateINSTREAM(instream);
IF DOMDocument.load(instream) THEN BEGIN
<...>
END;
END;

this works inside the table where the blob-field is placed, but maybe you need a calcfields on the blobfield befor you create the instream ?

The XMLDOM is not created by the Load method. You will have to explicitly create the object before you can load it. So you will need to do this:

IF ISCLEAR(MSDOM) THEN
  CREATE(MSDOM);
MSDOM.Load(YourXmlHere);
