Access violation while trying to create an element

adidasadidas
in XML Development
Hey guys!

I'm kind of new to XML using VC++ 6.0.
I know XML DOM and XML MiniDOM from python...

anyway, I try to create an element, or a node,
and as I run my little application it carshed due to "Access violation"
the exception occures in the functions
raw_createElement(...) and raw_createNode(...)

it happens all the time, and frankly I really don't know what the heck is wrong in there....

here is a fragment of my source:

#define PHONEBOOK_NODE _T("Node")
sprintf(node, "%ld", m_NodeID);
l_XMLNode = m_pDomDocument->createNode(l_vtType, _T(node), _T(""));
l_XMLElement = m_pDomDocument->createElement(PHONEBOOK_NODE);

where:
m_pDomDocument is IXMLDOMDocument2Ptr
l_XMLNode is IXMLDOMNodePtr
l_XMLElement is IXMLDOMElementPtr

I'll be very glad (and so my boss) if someone will be kind to
share his or her opinion about that...

thanx,
Adidas

    Did you initialize the interfaces? If you didn't then you must do that before trying to call any of their members.

    yes, off-course, I initialized the m_pDomDocument.
