c++ - QNetworkAccessManager finished signal is not emitted when compiled in release mode (VS 2005) -

-

i have class reads web pages. works expected when built in debug mode in visual studio, doesn't work when built in release mode.

basically, qnetworkaccessmanager's finished signal never gets emitted.

i have code stripped bare working minimum , still doesn't work. have tried use qtnetworkd4.lib in release mode (the same library in debug mode) , disable optimization, no effect.

qt version 4.4

edit
here sample code.

header:

#include <qnetworkaccessmanager> #include <qnetworkreply> #include <qnetworkrequest> #include <qstringlist>  class webreader : public qobject{     q_object  public:     qstringlist *pagedata_;     webreader();     ~webreader();     void fetch(const qstring &url);  public slots:     void slotreplyfinished(qnetworkreply *reply);  protected:     qnetworkaccessmanager *netmanager_;  private:      qnetworkreply *netreply_; };

cpp:

webreader::webreader(){     netmanager_ = new qnetworkaccessmanager(this);     pagedata_ = null;     connect(netmanager_, signal(finished(qnetworkreply *)),                              this, slot(slotreplyfinished(qnetworkreply *))); } webreader::~webreader(){     }  // send request read web page void webreader::fetch(const qstring &url){     netreply_ = netmanager_->get(qnetworkrequest(qurl(url))); }  // slot accepts read data webpage void webreader::slotreplyfinished(qnetworkreply *reply){     if (null != pagedata_){         delete pagedata_;     }     pagedata_ = new qstringlist(qstring(reply->readall()).split(qstring("\n")));     netreply_->deletelater(); }

as see, stripped down bare minimum works in debug mode.

copy libeay32 , ssleay32 same folder program.

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt

the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
