insertion

My application is based on Hibernate 3.2 and Spring 2.5. Here is the transaction management related snippet from the application context: <tx:annotation-driven transaction-manager="txManager"/> <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> <property name="nestedTransactionAllowed" value="true"/> </bean> <bean id="transactionTemplate" classs="org.springframework.transaction.support.TransactionTemplate"> <property name="transactionManager" ref="txManager"/> </bean> <bean class="org

I have ds code for inserting values in a binary search tree using recursion. The problem is that the root always remains null. Upon execution, the 1st printf() prints 10 but the 2nd printf (after insertRec(10)) does not print anything as root is null. #include<stdio.h> #include<malloc.h> struct llist { int data; struct llist *left; struct llist *right; }; typedef struct llist node; void insertRec(node *r, int num) { if(r==NULL) { r=(node*)malloc(sizeof(node)); r->data=num; r->left=NULL; r->right=NULL; printf("%d ",r->data); //1st printf } else { if(num < r->data) insertRec(r->left, num); else

Is it possible to define a static insertion operator which operates on the static members of a class only? Something like: class MyClass { public: static std::string msg; static MyClass& operator<< (const std::string& token) { msg.append(token); return *this; // error, static } }; alternatively: static MyClass& operator<< (MyClass&, const std::string &token) { MyClass::msg.append(token); return ?; } This is how I would like to use it: MyClass << "message1" << "message2"; Thank you! If all the members of MyClass are static, it's possible to return a fresh instance. However, returning a

I need to transfer some data from another database. The old database is called paw1.moviesDB and the new database is paw1. The schema of each table are the following. Awards (name of the table)(new DB) Id [PK] Serial Award Nominations (name of the table) (old DB) Id [PK] Serial nominations How do I copy the data from old database to the new database? Nate I just had to do this exact thing so I figured I'd post the recipe here. This assumes that both databases are on the same server. First, copy the table from the old db to the new db (because apparently you can't move data between databases).

How can I get a device Id and other description on insertion of USB device? I've found an example how to get notified about USB device insertion/removal. But how to get device desrtiption info? Here is my code snippet: WqlEventQuery q; ManagementScope scope = new ManagementScope("root\\CIMV2"); scope.Options.EnablePrivileges = true; try { q = new WqlEventQuery(); q.EventClassName = "__InstanceDeletionEvent"; q.WithinInterval = new TimeSpan(0, 0, 3); q.Condition = @"TargetInstance ISA 'Win32_USBControllerdevice'"; w = new ManagementEventWatcher(scope, q); w.EventArrived += new
