QSharedMemory::handle doesnt exist error [SOLVED]

Raveendra

I'm trying this bellow QT code :
@
#include <QtCore/QCoreApplication>
#include<QDebug>
QSharedMemory g_objSharedMemory(QString("Shared Memory"));

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    if(g_objSharedMemory.isAttached()==false)
    {
        qDebug()<<"Shared memory is not attached !!!!trying to attach it\n ";
        qDebug()<<g_objSharedMemory.errorString();
        if(g_objSharedMemory.attach()==false)
        {
            qDebug()<<"Failed to attach shared memory to the process!!!!";
            qDebug()<<g_objSharedMemory.errorString();
            return 0;
        }
    }
    
    return a.exec&#40;&#41;;
}@

I'm failed to attach the shared memory segment to the process. I'm building this code on windows xP
I'm getting "QSharedMemory::handle doesnt exist error".
How can i fix this error ?
