life becomes simple if u use .net classes like:

XmlSerializer, XmlTextReader, TextWriter.

u have to include respective namespaces, System::Xml, System::Xml::Serialization.

I hope it helps.

You have to use the XML DOM to read/write the XML using the vc++. See the article Introduction to Using the XML DOM from Visual C++[^]

There is a save method for the IXMLDOMDocument. so can add nodes to the XML file using the appendChild function and when you are done adding all the nodes and sub nodes, you can call the save function, which will flush the content of the IXMLDOMDocument to the specified file in the XML format.

Now Ive Created an Xml file.....
By Adding new item(.xml) in project settings...

Ive started with a dialog box....
on pressing ok..the file is opened...

The CODE IS:

void CXMLDOMFromVCDlg::OnBnClickedEnter()
{
XmlDocument *docXML = new XmlDocument;

docXML->LoadXml(S"");

}

Ive Also added :

#import <msxml.dll> named_guids
using namespace MSXML;

.................. in stdafx.h

im doing this using MFC AppWizard.....

this is not working......

im getting so many ERROR:

: 'XmlDocument' : undeclared identifier

: 'docXML' : undeclared identifier

: syntax error : identifier 'XmlDocument'
: left of '->LoadXml' must point to class/struct/union

: managed targeted code requires '#using <mscorlib.dll>' and '/clr' option

no no. There is nothing called XmlDocument, it is IXMLDOMDocument. Please read the article I suggested...

Instead of creating an XML file by coding...
i tried to create it using AppWizard...thatz all
............ I made the changes u said....

void CXMLDOMFromVCDlg::OnBnClickedEnter()
{
IXMLDOMDocument *docXML = new IXMLDOMDocument;

docXML->loadXML(S"");

}

but i get the following ERRORS......

ERROR: 'IXMLDOMDocument' : cannot instantiate abstract class

ERROR: managed targeted code requires '#using <mscorlib.dll>' and '/clr' option

Y is it?????

****************************************************

I also tried:::::::::

void CXMLDOMFromVCDlg::OnBnClickedEnter()
{
IXMLDOMDocumentPtr docPtr;
docPtr.loadXML("XMLDOMFromVC.xml");

}

but i get similar errors.....

I dont know how you generate this codes, using App wizards. Confused | :confused:

Any way this is the code for creating the IXMLDOMDocument.

IXMLDOMDocument* pXMLDoc = 0;
HRESULT hr = CoCreateInstance(CLSID_DOMDocument, NULL, CLSCTX_INPROC_SERVER, 
             IID_IXMLDOMDocument, (void**)&pXMLDoc);

Please understand that this is COM. You cannot simply allocate a com pointer using the new.
