Re: [xml] Compression problem using Zlib

["Arda Tekin" <arda tekin softhome net>]

Igor,
I changed the the library path "libxml2-2.5.5.win32" with the new library
which you send me for zlib compatibility. Updated the new libxml2.dll which
is in my ./Debug folder with the program. But when I set compression flag
and call the xmlSaveFile I get an Access Violation Error. If I dont use
compression option there is no problem..

#define _WINDOWS
#define ZLIB_DLL
#include "zlib.h"

#include <libxml/tree.h>
#include <libxml/parser.h>

..xml Doc Creation process..

int nComp = xmlGetDocCompressMode(doc);
xmlSetDocCompressMode(doc, 2);
//OR xmlSetCompressMode(2);

xmlSaveFile("c:\\VEReq.xml", doc);//ERROR Access Violation

Igor what 's the reason of this error?
Thank you,
Arda
