Hello friends, I hope you all are doing great. In today's tutorial, we will discuss Validation in ASP.NET MVC. It's our 14th tutorial in ASP.NET MVC series. In our previous tutorial, we have seen Model Binding in ASP.NET MVC and you have seen we have created a View for our Model class.
In today's tutorial, we are gonna add some validations on the data provided by the users in those Text box fields. We will place some constraints like the age must be above 13 or the characters of name must be between 4 to 20. So, let's have a look at How to deal with Validation in ASP.NET MVC:
Validation in ASP.NET MVC
Validation uses built-in attribute of ASP.NET called DataAnnotations and is used to validate inputs provided by the user.
Validation is a very ...
Hello friends, I hope you all are having fun. In today's tutorial, we will have a look at Introduction to Polymorphism in C#. It's our 16th tutorial in C# series and polymorphism is considered as a main pillar of object oriented programming.
In our previous tutorial, we have seen a detailed Introduction to Inheritance in C# and along with it, we have also discussed How to hide a Method in Parent Class, if the same method exists in Child class. This Method Hiding is actually the basis of Polymorphism, so let's discuss it out in detail:
Introduction to Polymorphism in C#
Polymorphism in C# enables the user to invoke a Child Class Method & override the Parent Class Method, using a Parent Class Reference variable.
In our previous lecture o ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at General Overview of Cisco CCNA Routing and Switching Certification. For communication to be enhanced, a proper network needs to be ensured at all times. There are many professionals who help in configuring your network in order to guarantee a hassle-free experience when communicating. This includes making the Internet accessible and also making sure that there are no interruptions in the network.A professional in this field needs to have mastery in two major aspects if to speak about boosting networks. These aspects are routing and switching.
Switching encompasses the connection of various devices to one network and in most instances, within the same buildin ...
Hello everyone! I hope you will be fine and having fun. Today, I am going to give a detailed Introduction to Relay. In this tutorial, we will learn the basics of relays, the working principle of relays, the types of relays and their applications in detail. A relay is a simple automatic switch that opens and closes the circuit(either electronically or mechanically) based on its input signal. A relay is an electromechanical switch that uses electromagnetism from a small current or voltage to switch higher current or voltage for different appliances. When a relay is in a Normally Open (NO) state, no current passes through it and when the relay is energized, the current starts to flow and we can say the relay is in a Normally Closed state. You should also have a look at Relay Interfacing with ...
Hello friends, I hope you all are doing great and having fun with your lives. In today's tutorial, I am going to share How to interface Arduino with GLCD. I am gonna design a Proteus Simulation in which I will interface Arduino GLCD together. GLCD is also called Graphical LCD so today we are gonna do some designing on the LCD. The GLCD I am going to use is ks0108 and its model in Proteus is LGM12641BS1R and I have shared the complete Simulation along with Arduino Code below for download. But I would suggest you to design it on your own so that you could get the most out of it. If you haven't worked on the LCD before then I would suggest you to read How to Interface Simple LCD with Arduino.
Moreover, I am quite happy to announce that we have starte ...
Welcome to the next tutorial of our raspberry pi programming tutorial. The previous tutorial showed us how to set up a weather station using the Internet of Things (IoT) on a Raspberry Pi 4. First, we studied how a weather station works on a fundamental level. Then we developed a Python script to collect data from the station. In contrast, we'll construct an automatic gate using a Raspberry Pi, a load cell, and an HX711 weight sensor.
These pressure-sensitive gates are common in shopping centers and showrooms; they open when someone is in the immediate vicinity and close again when the person is out of sight. Like the Automatic Gate, we just made, this one will open in response to weight or pressure and stay that way until the force is removed. If ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Convert m File into p File in MATLAB. Now the question arises that why we need to do that? & the answer is if you want to protect your code and don't want anyone to access it then you need to your Convert m File into p File. P File is like an encrypted file which performs the same functionality as your original m file but no one can get the code out of it.
Like me explain it with an example, suppose you are some sort of developer and you have created some code for a company and now you want to protect your code and just send the company some sort of software. MATLAB has a function in which you convert your m-file into p-file and no one can open ...
Hello everyone, I hope you all are doing great. In today's tutorial, I am going to share a new version of Heart Beat Sensor Library for Proteus i.e. version 2.0. I have already posted the First Version of the Heart Beat Sensor Library for Proteus in which you can use the TestPin and if it's HIGH then a single heartbeat pattern will start. So, if you use that library, you will always get the same result for your heartbeat. But in this 2nd version, I have added variable heartbeat depending on the value of TestPin. I will show you in detail, how to do it.
I have also posted a project Heart Beat Counter using Arduino in which I have shown you How you can use this sensor and count your Heart Beat. So, let me show you How you can use this new Heart ...
Hello friends, I hope you all are fine and having fun with your lives. In today's post, we are gonna have a look at How to use C# ArrayList. I am gonna explain it in detail what is C# ArrayList and how to use C# ArrayList. But before going into the details of today's tutorial, you must first have a look at my previous tutorial which is How to use C# Array??? because C# ArrayList is quite similar to C# Array.
I am gonna use the same project which we have designed in our first lecture on C# named as Introduction to C# Windows Forms. So, you should also use the same project and as we know this project has one Button and one Text box. Just a recall that I have changed the Text of the button to Click Here and the name of the button to ClickHere. Simila ...
Update: Here are the latest versions of this library: PIR Sensor Library for Proteus V3.0 and PIR Sensor Library for Proteus V2.0.
Hello friends, hope you are doing well. Today, I will share a new PIR Sensor Library for Proteus. PIR Sensor module is not available in Proteus so we can't use it in
our simulations. But today, I will share a new PIR Sensor Library
for Proteus which can easily simulate PIR Sensor in Proteus software.
We are quite happy that we are helping engineers by sharing these new Proteus Libraries.We all know about PIR Sensor but if you don't know then first read Interfacing of PIR Sensor with Arduino.As a quick review, a PIR sensor is used to detect motion in the environment and is commonly known as a motion sensor. It's quite helpful in security projects ...
