I've been producing videos instead of text blogs lately. The video shared here is another addition to the same chain. I hope you'll find it useful.

|Network Programming 3487 in list of BCS courses of AIOU|
I am an Allama Iqbal Open University graduate, I passed BCS in 2005. I've been working as a programmer ever since, although I've changed track a few years ago and moved to automated software testing. I must say Open university has got a very good program in place and if someone's got a fire in their belly, AIOU has got the gasoline to turn it into an inferno. It has produced bright stars like my friend & colleague Akhter Sheikh.
AIOU Network Programming course code 3482You can check the detailed curriculum of the course here
This course is using Winsock 2 with VC++ which is not commonly used in the market these days. I suppose using C# .Net instead would have been more beneficial for the students, because it is a widely used programming language.

An online video course about TCP/IP socket programmingNetwork programming course on AIOU website came to my attention one day while I was casually browsing list of courses included in their bachelor of computer sciences program these days.
My online course about TCP/IP socket programming is hosted on Udemy.com and it can be helpful for people who are either taking this course right now or have taken the course some time in past already.
I have created a free discount 100% coupon for my junior university fellows. You don't pay anything, just click the link given below and watch the stuff. I'm sure it will be worth your time.
The first section of the course explains several important computer networking concepts which are used for socket and network programming. These concepts are universal, which means useful for C++/C#/Java/Python or any other programming language.
The remaining parts of the course show practical coding examples and programming techniques which are useful in general.

Prologue: How I got into network programming?Before I became automated software testing professional, I luckily had a chance to do network programming in more than one language. I started in C# .Net for a telephony server application that used TCP/IP sockets to share data between a Panasonic POTS PBX (Microsoft TAPI 2.1) and various clients. Later on, I used Winsock in a C++ based project. I even used POSIX sockets for a short project while working with an Alcatel Lucent IP PBX(CSTA).
I had no idea back then that in the years to come I will be using sockets again and again. I used UDP sockets in Java programming language for an Android remote control app(iSymphony 2.1), that was some time in 2012/2013. User data gram sockets are considerably different as compared to connection based TCP/IP sockets.

First of all create a new blank Cocos2d-X C++ project as shown here.
Now follow the previous tutorial(Handle Touch Input in Cocos2d-x Mobile Game) in this series. Don't add the business logic code inside HelloWorld::OnTouchEnded callback function.
I would love to make this article stand alone by describing all the steps here but I can't do that due to lack of time. I hope it won't hurt much since the other articles are reasonably well written(at least I think so).
Now go inside HelloWorld::OnTouchEnded callback funciton in HelloWorldScene.cpp and add following to the callback
auto mainScene = getChildByName("mainscene"); auto lblHello = mainScene ->getChildByName("lblHello"); auto vecLocationOfTouch = touch ->getLocation(); CCLOGERROR("onTouchEnded x: %f y: %f", vecLocationOfTouch.x, vecLocationOfTouch.y);
By doing this you will have a handle to the "Hello World!" label you created by following earlier tutorials.
Next we need to animate the label on touch. We will use Cocos2d-x MoveTo action in this case and supply it the vector vecLocationOfTouch.
The exact code to make the label run around the screen chasing your mouse clicks or screen taps is given below.
lblHello ->getActionManager() ->removeAllActions(); auto actMoveTo = MoveTo::create(2.0, vecLocationOfTouch); lblHello ->runAction(actMoveTo);
You can see the removeAllActions() method call before creating the action, I'm not sure if its necessary but still I kept it there as it's not causing any harm either.
I created a moveTo action and provided it with the speed of the movement as first parameter and the end location of the animation in the second parameter.
I wish I had a decent screen capture software, I would be posting videos of final results too.
Feel free to ask questions and get in touch.
