Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at Form Validation in ASP.NET Core. It's our 15th tutorial in ASP.NET Core series. In our previous lecture, we have created a Registration Form for our engineering website. But we haven't added any validations on the submitted data.
So, even if users don't fill any boxes and just hit the Register Button, a new user will be created without any personal info. So, today we will place some checks on these text boxes to validate the user submitted data. So, let's get started with it:
Form Validation in ASP.NET Core
Validations in ASP.NET Core are available in the form of attributes & Tag Helpers.
Validation Attributes are applied on Properties in Model clas ...
Hello everyone, hope you all are fine and having fun with your lives. In today's post, I am going to share How to generate PWM in 8051 Microcontroller. PWM is an abbreviation of Pulse Width Modulation and is used in many engineering projects. It is used in those engineering projects where you want an analog output. For example, you want to control the speed of your DC motor then you need a PWM pulse. Using PWM signal you can move your motor at any speed from 0 to its max speed. Similarly suppose you wanna dim your LED light, again you are gonna use PWM pulse. So, in short, it has numerous uses. If you are working on Arduino then you should read How to use Arduino PWM Pins.
PWM, as the name suggests, is simply a pulse width modulation. We take a pu ...
Welcome to the next tutorial on our raspberry pi four python programming. In the previous article, we built a system that recognizes when two people are in physical contact using OpenCV and a Raspberry Pi 4. We used the weights from the YOLO version 3 Object Recognition Algorithm to implement the Deep Neural Networks part. Regarding image processing, the Raspberry Pi consistently comes out on top compared to other controllers. A facial recognition program was among the earlier attempts to use Raspberry Pi for sophisticated picture processing. In today's world of cutting-edge technology, digital image processing has expanded rapidly to become an integral feature of many portable electronic gadgets.
Digital image processing is widely used for such t ...
Hey peeps! Are you excited to begin with the new chapter in Python? Till now, we have been learning the data types and their related concepts. Now, we are starting a new chapter where you will learn the details of Object Oriented Programming or OOP. We are moving towards the advanced level of programming in Python, and here, you will go through the complex but interesting concepts that will show us the fascinating results on the screen. This will be more clear when you will know the basic information about the OOP, but before going deep, we will go through the headlines of the lecture:
How do you classify the programming languages?
How do you introduce the OOP?
Why object-oriented programming is important in Python?
How do you define class and objects in OOP and how are they connected? ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at HTML Helpers in ASP.NET MVC. It's our 12th tutorial in ASP.NET MVC series. I know every tutorial is a new concept for you to understand but we have to cover all of them before starting working on our project in ASP.NET MVC.
If you have worked on ASP.NET web forms or C# / Visual Basic projects then you must be aware of toolboxes, from where we can drag and drop our visual components like textbox, editbox, button etc. But in ASP.NET MVC applications, we don't have this luxury of drag and drop. Instead we have HTML Helper classes which are used to created these html components in ASP.NET MVC. So, let's have a look at How to use HTML Helpers in ASP.NET MVC: ...
Hey learners! Welcome to the new lecture on deep learning, where we are using TensorFlow to learn it with the help of Python. Previously, we worked on the syntax of Python, and now it's time to discuss the variables in detail. There are some variables that you will learn about as well as get hands-on experience within TensorFlow. These are important concepts that will help you throughout your coding career. If you are new to programming, this is a crucial concept for you, and if you know it already, you can use this tutorial to polish your concepts. We will move forward after looking at the list of content for this lecture:
What are the variables in Python?
How do you assign the value to the name of the variable in Python?
What are some rules to define the name of the variables?
How ...
Greetings Learners! Welcome to the new lecture on Python. Today we are moving towards an interesting and important concept. If you have come from a programming background, then you must know about the workings of loops. To make the repetition of the same sequence, we use loops. We are familiar with the sequences in detail as we have learned them in the previous lectures and have received the concept in the recent lecture. If you want to be a programmer, then you can not move forward without a solid base of loops; therefore, in this lecture, we will learn the concept of loops from scratch and then go on to a deep understanding of each loop in the next episodes. So have a look at the concepts that you will learn today.
What are the loops?
How do we understand the concept of loops from scra ...
We've all heard that clicking on links or attachments can lead to identity theft of sensitive, personal information. And while it's true - if you're not careful, you could be leaving yourself open to hackers and other dangers. But what most people might not know is the difference between "hacking" and "data theft". In this post, we outline the steps data security engineers recommend you take to protect yourself from these different types of threats.
What do data security engineers recommend for people who don't work in security?
Data security engineers are not your everyday IT professionals, so what do they recommend for parts of the population who aren't working in IT?
Data security engineer advice for regular Internet users

Greeting, and welcome to the next tutorial of our raspberry programming tutorial. In the previous tutorial, we learned how to build a smart attendance system using an RFID card reader, which we used to sign in students in attendance in a class. When it comes to building a face-recognition program on a Raspberry Pi, this tutorial will show you how. Two Python programs will be used in the lesson, one of which is a Training program that analyzes a collection of photographs of a certain individual and generates a dataset. (YML File). The Recognizer application uses the YML script to detect a face and afterward utters the person's name when the face is detected.

Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to how to print from a Raspberry pi. We also discussed some libraries to create a print server in our raspberry pi. We will learn how to take screenshots on Raspberry Pi using a few different methods in this lesson. We will also look at how to take snapshots on our Raspberry Pi using SSH remotely.
Why should you read this article?
This article will assist you when working with projects that require snapshots for documenting your work, sharing, or generating tutorials.
So, let us begin.
Screenshots are said to be the essential items on the internet today. And if you have seen these screenshots in tutorial videos or even used them in regular commu ...
