Thanks you for your help.

What are the errors?
Are you writing 'using namespace std;' in your program?

What are the errors?

yes i am writing 'using namespace std ;' and the errors are

error C2228: left of '.open' must have class/struct/union type
error C2228: left of '.eof' must have class/struct/union type
error C1903: unable to recover from previous error(s); stopping
compilation
Error executing cl.exe.

and my header file is here:

#ifndef _XML_H
#define _XML_H

#include<fstream>
#include<string>
using namespace std;

class XML
{
private:

ifstream fileread;
ofstream filewrite;

public:

// For reading file and inserting the key and value pairs into
XML file
static void readfile(char *infile,string key1,string
text1,string str_value,string val);

// Function for converting the function parameters into XML file
static void writeXML(char *infile,string val,char *path);

// retrieving the value
string getValue(char *infile,char *path);

};
#endif // _XML_H

yes i am writing 'using namespace std ;' and the errors are

error C2228: left of '.open' must have class/struct/union type
error C2228: left of '.eof' must have class/struct/union type

those errors don't seem to be related to either the fstream header
or the ifstream header.

The error message looks like VC++ generated it. If so there is a line
number next to it. What line does it refere to?

You probably used a pointer to an ifstream object as an ifstream object.
For example:

ifstream *pifs;
....
pifs.open("xmldata.xml");

or used a whatever object that wasn't an ifstream.

(etc.)

You might find that you need
#include <istream>
and/or
#include <ostream>
too.

Thanks you everybody
i am writting 2 programs in VC++ 6.0, one for XML files the header is
up i have no problem which them it is ok, and the second programm is a
dynamic table to memory some data typ is ok. but i want to put the
both pragrams together (2 classes in 1) and i don´t any code of
program and try to compile alone the xml.cpp file and i become this
errors.

Compiling...
xml.cpp
\config\xml.cpp(164) : error C2228: left of '.open' must have

here are the errors line from the xml.cpp

the first ==> fileread.open(infile,ios::in);

the second ==> while(!fileread.eof())

here are the headers of the both programs.
