Writing xml with mfc app

Hello,

I want to write an xml file on a button click.
Under the button I have

XmlTextWriter w = new XmlTextWriter("D:\\rich\\test.xml");
w.WriteStartElement("x","root","urn:1");
w.WriteStartElement("y","item","urn:1");
w.WriteEndElement();
w.WriteEndElement();
w.Close();

but I get an error message saying that w cannot be destroyed. I got this code from the ms web stie and cannot work out why it is saying it.

I can write a blank empty file by
CreateFile(D:\\rich\\test.xml, FILE_WRITE_DATA, FILE_SHARE_READ, NULL, CREATE_NEW,FILE_ATTRIBUTE_NORMAL,NULL);
but I need it to contain some xml dependent on the options selected in my MFC form

Thanks in advance

Try w.Flush() before w.Close()

Hi nonubik,
I'll try that over the next couple of days. I was wondering if it was to do with the scope of my declaration. Should I declare the xmltextwriter outside of my button click?

Hi nonubik. I tried the w.Flush() and it didnt work

Worked it out. I think I was getting confused with C# and c++

String* path = new String("D:/rich/test.xml");
XmlTextWriter* w =new XmlTextWriter(path, 0);
w->WriteStartElement("MetaData");
w->WriteAttributeString("Tracks", "V");
w->WriteAttributeString("Logged", "1");
w->WriteEndElement();
