VC2005编译过后，运行后xp报错。
VC2005是没有任何补丁的原始版本。
MingW编译，可以运行。
mingw版本
ming32-make 3.81
ming32-g++ 3.4.2
哪位高人可以告知一二。

源代码如下。

#include <QApplication>
#include <QtGui>
class MyApp;
class MyApp:public QApplication{
public:
MyApp(int & argc,char ** argv);
QString selfName;
QString getName() const;
};
MyApp::MyApp(int & argc,char ** argv):QApplication(argc,argv){
//int i=0;
char * n=argv[0];
while(*n !='\0'){
selfName += *n ;
n++;
}
delete n;
}
QString MyApp::getName()const{
return selfName;
}
class MWin:public QWidget{
private:
int data;
QString str;
public:
MWin(MyApp * theApp);
};
MWin::MWin(MyApp * theApp){
data=5;
QLineEdit * lblmsg=new QLineEdit(theApp->getName());
QVBoxLayout * layout=new QVBoxLayout;
setLayout(layout);
layout->addWidget(lblmsg);
QSettings settings("./settings.ini",QSettings::IniFormat);
if(settings.contains("App/language")){
QString strNowLang=settings.value("App/language").toString();
QSettings lang(settings.value("App/language").toString()+".ini",QSettings::IniFormat);
if(lang.contains("Title"))
{
this->setWindowTitle(lang.value("Title").toString());
}
else
{
this->setWindowTitle("DefaultTitle");
lang.setValue("Title","TitleReadedFromFile");
lang.sync();
}
}
else
{
settings.setValue("App/language","English");
settings.sync();
}
resize( sizeHint() );
}
int main(int argc,char * argv[]){
MyApp app(argc,argv);
app.setOrganizationName("Qiyezi");
app.setApplicationName("TestSoft");
MWin mw(&app);
mw.show();
return app.exec();
}
