BLOB 2/from XML.Attribute

rst

dear collegues,

how can I import/export BLOB from/to XML.Attribute ?

(MS XMLDOM)


best regards, rst

rmv_RU

XML Text Node object ('Microsoft XML, v3.0'.IXMLDOMText) has SubstringData method, you can use it for reading large texts.
Also, look at this topic viewtopic.php?f=23&t=44086 .

thank You, rmv.
some questions please.

can I use Text Node for put binary data into it's value ?

if no, how can I encoding binary to base64 by MSXML libraries more simply ?

and how can I point XML data type in case of external base64 encoding ?

rmv_RU

Try to use AdoStream object in binary mode and xmlNode.nodeTypedValue to manipulate with binary data.

about types

IXMLDOMAttribute.value is Navision type - Variant and COM type - VARIANT *

methods IXMLDOMText.substringData and IXMLDOMText.appendData
http://msdn.microsoft.com/en-us/library ... 85(v=vs.85).aspx
http://msdn.microsoft.com/en-us/library ... 44(v=vs.85).aspx
these methods have BSTR and BSTR * data types for parameters "data"
F5 hot key diplays BSTR as type for parameter/result value "data" in Navision, and no more.

my main question is - how should I create InStream OutStream from Navision for manipulate with "data"
intuitively there must be some functions MSXMLDOM.CreateIn(Out)Stream generating these streams

say me their names my friends )
or break my hopes ...

PS - little question : how can I write URLs for they work correctly ?
