In this video I am going to show How to Set Up Python Development environment in Visual Studio Code in windows 10. I am also going to show ow to debug your python code using vs code. This process will also cover How to Install Python and Visual Studio Code for Windows 11. You are goint to Learn how to use the Visual Studio Code which is a cross-platform, free, and open source for all your Python development. We will see how to add Python Extension in VScode, add linting, add debugging and more.
Learn how to setup Python in Visual studio Code, which is free to install and use. VS Code is an open source source-code editor and debugger, developed by Microsoft. Python is a powerful, interpreted, object-oriented programming language.
How to Run Python Using Visual Studio Code
Visual Studio Code is a popular code editor that provides a powerful and user-friendly environment for programming in Python. In this tutorial, you will learn how to run Python in Visual Studio Code on Windows 11.
To get started, you will need to download and install Visual Studio Code on your Windows 11 computer. Once you have installed the editor, you can install the Python extension for Visual Studio Code, which will enable you to write and run Python code within the editor.
To run Python in Visual Studio Code, you can either create a new Python file or open an existing Python file. Once you have a Python file open, you can use the built-in terminal within Visual Studio Code to run your Python code.
To run Python code in the terminal, you can use the command "python" followed by the name of your Python file. This will execute your Python code and display the output in the terminal

In this tutorial we are going to learn about how to use charts control in c# visual studio.
charts are very important in c# visual studio.it can help in represent data in bar form.
which helps to understand data in application easily. there are various types of charts.
Bar charts and Pie charts.
Bar charts are used to represent data in bar form.
while pie charts are used to represent data in percentage form.
Methods and events of the Chart Windows control.
Two important properties of the Chart class are the Series and ChartAreas properties, both of which are collection properties. The Series collection property stores Series objects, which are used to store data that is to be displayed, along with attributes of that data. The ChartAreas collection property stores ChartArea objects, which are primarily used to draw one or more charts using one set of axis.
The DevExpress Chart Control for WinForms (ChartControl) allows you to visualize data as 2D and 3D charts, including bar, area, line, pie, and stock charts, and much more.
Learn the Basics
The following topics explain fundamental chart terms:
Diagram
Data Point, Its Argument and Value
Series and Series Views
Axes and Panes
Follow these step-by-step tutorials to create your first chart application:
Lesson 1 - Create a Simple Unbound Chart
Lesson 2 - Create a Chart using the Chart Designer
Lesson 3 - Bind Chart Series to Data
Lesson 4 - Use a Series Template for Auto-Created Series
#
Series Views
The Charts suite ships with dozens of 2D and pseudo-3D chart types for your data: line, stacked bar, pie, and others.
2D Series Views
3D Series Views
You can also combine multiple views (for example, bar and line) within the same chart: Series View Compatibility.
#
Load and Shape Data
A chart can operate in bound or unbound mode. In unbound mode, you can manually create and position series points. In bound mode, a chart or an individual series visualizes data from its data source (an object that implements the IList
, IListSource, or IBindingList
interface and is assigned to the chart or series DataSource property).
The topics below describe how to load data to a chart and configure data representation:
Create Points Manually
Bind a Series to a Data Source
Generate Multiple Series Based on a Template
Create a Real-time Chart
Display Large Data
Create a Drill-down Chart
Filter Series Data
Sort Series Data
Aggregate Data Points
Calculate Summaries
Display a Chart Based on Calculated Field Data
Plot a Histogram
Display Top N Points
Integrate With a Pivot Grid
Configure Work Time and Workdays
Handle Empty Points
Chart Element Configuration
Various chart elements allow you to customize chart behavior and appearance.
Series
A collection of related data points on the chart surface is called “series”. The appearance of these data points and the entire series depend on the view. You can also use point colorizers, series colorizers, and segment colorizers to create condition-based appearances.

Mastering C# Database Programming
Accessing Data from a database is one of the important aspects of any programming language. It is an absolute necessity for any programming language to have the ability to work with databases. C# is no different.
It can work with different types of databases. It can work with the most common databases such as Oracle and Microsoft SQL Server.
It also can work with new forms of databases such as MongoDB and MySQL.
Connection – To work with the data in a database, the first obvious step is the connection. The connection to a database normally consists of the below-mentioned parameters.
Database name or Data Source – The first important parameter is the database name to which the connection needs to be established. Each connection can only work with one database at a time.
Credentials – The next important aspect is the username and password which needs to be used to establish a connection to the database. It ensures that the username and password have the necessary privileges to connect to the database.
Optional parameters – For each database type, you can specify optional parameters to provide more information on how .net should handle the connection to the database. For example, one can specify a parameter for how long the connection should stay active. If no operation is performed for a specific period of time, then the parameter would determine if the connection has to be closed.
Selecting data from the database – Once the connection has been established, the next important aspect is to fetch the data from the database. C# can execute ‘SQL’ select command against the database. The ‘SQL’ statement can be used to fetch data from a specific table in the database.
Inserting data into the database – C# can also be used to insert records into the database. Values can be specified in C# for each row that needs to be inserted into the database.
Updating data into the database – C# can also be used to update existing records into the database. New values can be specified in C# for each row that needs to be updated into the database.
Deleting data from a database – C# can also be used to delete records into the database. Select commands to specify which rows need to be deleted can be specified in C#.
Ok, now that we have seen the theory of each operation, let’s jump into the further sections to look at how we can perform database operations in C#.
SQL Command in c#
SqlCommand in C# allow the user to query and send the commands to the database. SQL command is specified by the SQL connection object. Two methods are used, ExecuteReader method for results of query and ExecuteNonQuery for insert, Update, and delete commands. It is the method that is best for the different commands.
How to connect C# to Database
Let’s now look at the code, which needs to be kept in place to create a connection to a database. In our example, we will connect to a database which has the name of Demodb.
In this C# sql connection tutorial, you will learn-
Fundamentals of Database connectivity
How to connect C# to Database
Access data with the SqlDataReader
C# Insert Into Database
Updating Records
Deleting Records
Connecting Controls to Data
C# DataGridView
Fundamentals of Database connectivity
C# and .Net can work with a majority of databases, the most common being Oracle and Microsoft SQL Server. But with every database, the logic behind working with all of them is mostly the same.
In our examples, we will look at working the Microsoft SQL Server as our database. For learning purposes, one can download and use the Microsoft SQL Server Express Edition, which is a free database software provided by Microsoft.

In this tutorial we are going to learn about how to use an Android List View.
it is very easy to create listview in android studio. Listview in Android is one of the most important widget in android
every application will be using listview in some way so stay and learn about listview and android development in detail.
Android ListView is a view which groups several items and display them in vertical scrollable list. The list items are automatically inserted to the list using an Adapter that pulls content from a source such as an array or database.
An adapter actually bridges between UI components and the data source that fill data into UI Component. Adapter holds the data and send the data to adapter view, the view can takes the data from adapter view and shows the data on different views like as spinner, list view, grid view etc.
The ListView and GridView are subclasses of AdapterView and they can be populated by binding them to an Adapter, which retrieves data from an external source and creates a View that represents each data entry.
Android provides several subclasses of Adapter that are useful for retrieving different kinds of data and building views for an AdapterView ( i.e. ListView or GridView). The common adapters are ArrayAdapter,Base Adapter, CursorAdapter, SimpleCursorAdapter,SpinnerAdapter and WrapperListAdapter. We will see separate examples for both the adapters.
ListView Tutorial With Example In Android Studio
List of scrollable items can be displayed in Android using ListView. It helps you to displaying the data in the form of a scrollable list. Users can then select any list item by clicking on it. ListView is default scrollable so we do not need to use scroll View or anything else with ListView.
ListView is widely used in android applications. A very common example of ListView is your phone contact book, where you have a list of your contacts displayed in a ListView and if you click on it then user information is displayed.
Adapter: To fill the data in a ListView we simply use adapters. List items are automatically inserted to a list using an Adapter that pulls the content from a source such as an arraylist, array or database.
ListView in Android Studio: Listview is present inside Containers. From there you can drag and drop on virtual mobile screen to create it. Alternatively you can also XML code to create it.

A Material Design "Outlined Button"; essentially a TextButton with an outlined border.
Outlined buttons are medium-emphasis buttons. They contain actions that are important, but they aren’t the primary action in an app.

An outlined button is a label child displayed on a (zero elevation) Material widget. The label's Text and Icon widgets are displayed in the style's ButtonStyle.foregroundColor and the outline's weight and color are defined by ButtonStyle.side. The button reacts to touches by filling with the style's ButtonStyle.overlayColor.

The outlined button's default style is defined by defaultStyleOf. The style of this outline button can be overridden with its style parameter. The style of all text buttons in a subtree can be overridden with the OutlinedButtonTheme and the style of all of the outlined buttons in an app can be overridden with the Theme's ThemeData.outlinedButtonTheme property.
Unlike TextButton or ElevatedButton, outline buttons have a default ButtonStyle.side which defines the appearance of the outline. Because the default side is non-null, it unconditionally overrides the shape's OutlinedBorder.side. In other words, to specify an outlined button's shape and the appearance of its outline, both the ButtonStyle.shape and ButtonStyle.side properties must be specified.
Flutter - Using OutlinedButton Widget Examples
This is a tutorial about how to use Flutter's OutlinedButton widget, including how to customize the style of the button.
OutlinedButton is a widget that allows you to easily create a Material Design's Outlined Button. This widget was introduced in Flutter 1.22. It's similar to a TextButton, but with an outlined border. Usually, this kind of button is used for important but non-primary actions.

In this tutorial we will learn about switch statements.switch statements in C# is multi way branch statement. it provides an easy way to dispatch execution to different parts of your code based on the value of an expression. it often provides a better alternative than a large series of if-else statements.
This is how it works:
The switch expression is evaluated once
The value of the expression is compared with the values of each case
If there is a match, the associated block of code is executed
The break and default keywords will be described later
C# - Switch Statement
A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each switch case.
The following rules apply to a switch statement −
The expression used in a switch statement must have an integral or enumerated type, or be of a class type in which the class has a single conversion function to an integral or enumerated type.
You can have any number of case statements within a switch. Each case is followed by the value to be compared to and a colon.
The constant-expression for a case must be the same data type as the variable in the switch, and it must be a constant or a literal.
When the variable being switched on is equal to a case, the statements following that case will execute until a break statement is reached.
When a break statement is reached, the switch terminates, and the flow of control jumps to the next line following the switch statement.
Not every case needs to contain a break. If no break appears, then it will raise a compile time error.
A switch statement can have an optional default case, which must appear at the end of the switch. The default case can be used for performing a task when none of the cases is true.
