.NET GENES

Hello, Here's a Visual Basic tutorial on how to create a CRUD (Create/Update/Delete) application using Windows Forms In .NET Core. The same concept is applied to a Windows Forms application in .NET Framework. Most of the concepts and logic were borrowed from the C# version here except that a different programming language is used. First is to create a Students table on your SQL Server Database using the script below. USE [TestDatabase] GO /****** Object: Table [dbo].[Students] Script Date: 03/31/2014 14:11:36 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[Students]( [ID] [int] IDENTITY (1,1) NOT NULL , [Name] [varchar](50) NULL , [Age] [int] NULL , [Address] [varchar](50) NULL , [Contact] [varchar](50) NULL , CONSTRAINT [PK_Students] PRIMARY KEY CLUSTERED ( [ID] ASC ) WITH (PAD_INDEX = OFF , STATISTICS_NORECOMPUTE = OFF , IGNORE_DUP_KEY = OFF , ALLOW_ROW_LOCKS = ON , ALLOW_PAGE_LOCKS =

Good day Gents! In this post, I will demonstrate the VB.NET version on how to create a WPF DataGrid application that has a check all checkbox behavior for selecting all rows using the MVVM Pattern. First is we need to create a .NET WPF Visual Basic project that targets the .NET framework with a project structure similar to the screenshot below. App.config Update your App.config's connection string with your local database connection. <configuration> <startup> <supportedRuntime version= "v4.0" sku= ".NETFramework,Version=v4.5.2" /> </startup> <connectionStrings> <add name= "products" connectionString= "data source=.;Initial Catalog=TestDatabase;Trusted_Connection=True;" providerName= "System.Data.SqlClient" /> </connectionStrings> </configuration> DBUtil.vb The DBUtil class will retrieve records from the database and u

Hi All, This article is the VB.NET version of this post Getting Started With Unity IoC Container Dependency Injection In .NET Core Using Entity Framework Core ORM And SQL Server . We will create a .NET Core Console Application that will utilize the Unity IoC Container for Dependency Injection, SQL Server and Dapper ORM. Instead of using Entity Framework, I'm using Dapper ORM coz EF does not support reverse engineering in .NET Core. There are existing power tools or other solutions on how to reverse engineer a database table but for now I'll just use Dapper. I'll be using Microsoft's sample database called ContosoRetailsDw as the datasource of this tutorial. Project Setup 1. Start off by creating a Visual Basic .NET Core Console Application targetting the latest framework which is .NET 5.0 2. Add three new folders Models, Repository and UnitOfWork. These folders contain the model and DAL classes used in this project. 3. Add the following NuGet packages: Dapper O
