Cannot open XML File

[manju 123]

Hi all. I am trying to open Xml file using parser.. I am using MSXML2.dll. When i debug It is throughing Exception in this line ///////////////////////////// EVAL_HR(objDOMDoc.CreateInstance("Msxml2.DOMDocument.2.0")); ///////////////////////// In this line i am getting Error... when I used MSXML4.dll..It is showing error "Cannot open MSXML4.dll.. any suggestions. Here is the code.. ////////////////////////////////

#include "stdafx.h"

#include "stdio.h"
#import "msxml4.dll"
using namespace MSXML2;
inline void EVAL_HR( HRESULT _hr )
{ if FAILED(_hr) throw(_hr); }

int main(int argc, char* argv[])
{
try
{
IXMLDOMDocumentPtr objDOMDoc;

	EVAL\_HR(CoInitialize(NULL)); 
	EVAL\_HR(objDOMDoc.CreateInstance(\_\_uuidof(MSXML2::DOMDocument40)));
	\_variant\_t varXml("C:\\\\book.xml");
	\_variant\_t varOut((bool)TRUE);

	objDOMDoc->async = false;
	varOut = objDOMDoc->load(varXml);
	
	if ((bool)varOut == FALSE)
	 throw(0);
	
	printf(\_bstr\_t(objDOMDoc->xml)) ;
	printf("\\n\\nPress ENTER to continue...\\n");
	getchar();
	//return 0;
}

catch(...)
{
	printf("Exception occurred");
	printf("\\n\\nPress ENTER to continue...\\n");
	getchar();
	return -1;
}

You better write "MSXML2.DOMDocument.2.0" is MSXML4.dll correctly installed?
