What is the use of virtual functions and virtual class?

A virtual function is a member function in the base class that we expect to redefine in derived classes. Basically, a virtual function is used in the base class in order to ensure that the function is overridden. This especially applies to cases where a pointer of base class points to an object of a derived class.

What is Datagramsocket explain in detail with example?

A datagram socket is the sending or receiving point for a packet delivery service. Each packet sent or received on a datagram socket is individually addressed and routed. Multiple packets sent from one machine to another may be routed differently, and may arrive in any order.

What is data gram packet in java?

Datagram packets are used to implement a connectionless packet delivery service. Each message is routed from one machine to another based solely on information contained within that packet. Multiple packets sent from one machine to another might be routed differently, and might arrive in any order.

What is GetData C?

GetData is a C library. The APIs it provides are described below. In addition to this C library, bindings are also provided to simplify using GetData in other programming languages. The library is designed to be robust, but does, at times, sacrifice exactness for speed.

What is virtual functions explain with suitable example?

A virtual function is a member function that you expect to be redefined in derived classes. When you refer to a derived class object using a pointer or a reference to the base class, you can call a virtual function for that object and execute the derived class’s version of the function.

Why do we need virtual functions?

Virtual functions ensure that the correct function is called for an object, regardless of the type of reference (or pointer) used for function call. Functions are declared with a virtual keyword in base class. The resolving of function call is done at runtime.

What is the function of DatagramSocket class?

The Java DatagramSocket class represents a socket for sending and receiving datagram packets. It is a sending and receiving point for a packet delivery service where each packet is individually addressed and routed.

What are the methods provided by DatagramSocket?

Java DatagramSocket Class

Method Description
boolean isConnected() It returns the connection state of the socket.
void send(DatagramPacket p) It sends the datagram packet from the socket.
void receive(DatagramPacket p) It receives the datagram packet from the socket.

Is there a guide for getdata/setdata functions in Visual Studio?

Unfortunately the most guides on the net that deals with getdata/setdata functions takes for granted that you are using Visual Studio with document outline but sometimes that choice isn’t available. Hopefully after this blog post you will find it easier to find the setdata/getdata functions in the report, know where to add a new field.

How do I get the data from a data object?

If dataObject.GetDataPresent (desiredFormat, noAutoConvert) Then ‘ If the desired data format is present, use one of the GetData methods to retrieve the ‘ data from the data object. data = TryCast (dataObject.GetData (desiredFormat), Byte ()) End If Returns a data object in a format specified by a Type object.

How do I see the number of a field in setdata?

If you only want to see which number a certain field has. Scroll to the bottom and you will find a list of the fields and numbers. Find the SetData function call. Add a field to the SetData function call. Make the SetData expression more readable. A numbered list of all the fields in the SetData function call.

How to add a field to a function call in setdata?

Then choose the Text Box Properties. Choose the Visibility setting and then look at the code for the expression. Here you have the code for the setdata function call with all the fields as parameters. If you would like to add a field to the function call you have to add it at the end so you won’t displace the other fields from the correct order.
