Qt with Visual Studio 2010

[Milica]

Hello,
I use Qt 4.8.5 open source with Visual Studio 2010, and when i build my simple code, i`ve got this error:

Unhandled exception at 0x53be45fa (QtGuid4.dll) in gotocelldialog.exe: 0xC0000005: Access violation reading location 0x0006463c.

and it stops in this:

#ifndef QT_NO_VALIDATOR
const QValidator *validator() const { return m_validator; }
void setValidator(const QValidator v) { m_validator = const_cast<QValidator>(v); }
#endif

which is part of the QtGui module of the Qt Toolkit.

And sometimes the same code build successful but without any output.f

Does anyone know what this mean ?
