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++[^]

life becomes simple if u use .net classes like: XmlSerializer, XmlTextReader, TextWriter. u have to include respective namespaces, System::Xml, System::Xml::Serialization.
This is a C++ forum, not a managed forum...

There is a
savemethod for theIXMLDOMDocument. so can add nodes to the XML file using theappendChildfunction and when you are done adding all the nodes and sub nodes, you can call thesavefunction, which will flush the content of theIXMLDOMDocumentto the specified file in the XML format. -

In case you haven't noticed, that fine and outstanding article haven't got any vote yet... :(. I couldn't believe..
I noticed myself yesterday and thought about a
CodeProjectbug since it is an unbelievable: the article had about22000views and no vote.If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

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

I even tried another browser to check whether it is a bug or not... Any way it shows two votes now :)
I was just wondering who were the two 5 voters :rolleyes: :-D

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: 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. -
