Implementing Timer and Counter of Loaded Strings on Web Form

Implementing Timer and Counter of Loaded Strings on Web Form
Rate this post

During the development of reporting forms, a user wanted to see the process of data loading from the database. He wanted the timer to start running after hitting the button, and as strings were received, their number was displayed on the form. I needed to implement this within an existing ASP.NET project.

OdataToEntity – an easy way to create .Net Core OData services

OdataToEntity – an easy way to create .Net Core OData services
Rate this post

When .Net Core was released, the old version of OData ASP.NET Web API turned out to be incompatible with the new platform. This fatal flaw allowed me to create my OData implementation on the .Net Core platform. After the creative rethinking of the previous implementation, I came to an understanding that it suffered from a complicated design with a lot of unnecessary abstractions. An idea to create an easy-to-use library that requires minimal coding came into my mind. I would like to present you OdataToEntity, the library for creating OData services without code writing; the only thing needed is data access context.

Rate this post

Introduction

PowerShell is a Shell included in Windows to automate tasks in the operative system and other applications like SQL Server, SharePoint and Internet Information Services. You can create reports, start services, check the hard drive space, verify the RAM and more.

PowerShell can now be installed in Linux, Docker, and Mac.

You can use loops, comparisons, conditionals and more to create powerful scripts to automate tasks like creating Virtual Machines or SQL Servers in Azure.

In this new article, we will learn how to use the script task to invoke PowerShell in C#. The script task in SQL Server Integration Services (SSIS) allows using C# or VB code to extend the SSIS features. Read More

Transparent Data Encryption and Always Encrypted

Transparent Data Encryption and Always Encrypted
Rate this post

If you need to store confidential data in your database, you can use data encryption. SQL Server supports encryption with symmetric keys, asymmetric keys, certificates, and password phrases. I assume that you, the reader, are already familiar with these terms. In this article, I will focus on two out of many encryption options provided by SQL Server:

  • Transparent Data Encryption (TDE)
  • Always Encrypted (AE)

ASP.NET Core MVC: Feature Folders

ASP.NET Core MVC: Feature Folders
4 (80%) 1 vote

The first version of ASP.NET MVC appeared back in 2009, and the platform (ASP.NET Core) was first relaunched last summer. During this time, the default project structure has remained almost unchanged: folders for controllers, views, and often for models (or perhaps ViewModels). This approach is called Tech folders. After creating a new ASP.NET Core MVC project, the organization structure of folders is the following:

Type Conversion in .NET

Type Conversion in .NET

Introduction

Such a simple topic as type conversion would seem to be unworthy of the whole article. In C#, there is a suitable operator “(T)value” and types that implement it. So, this topic may be considered as closed. However, for 14 years of .NET existence, BCL developers and other programmers have come up with other four ways to convert value types.

SSAS: Discipline, Accuracy, Attention to Details
Rate this post

Introduction:

This article is about working with Microsoft Analysis Services and a little bit about the repository on Microsoft SQL Server that SSAS is working with. I had to deal with not quite trivial things and sometimes I had to “jump over my head” in order to complete my task. I had to work between meetings. Sometimes the new functionality was discussed longer than it was developed. Often at meetings, I had to repeat the same thing several times. When I said that it’s hard for me to have a discussion for more than one hour, people looked at me with surprise and misunderstanding. Thanks largely to this situation, these nontrivial things about which I decided to write appeared.

Introduction to Temporary Tables in SQL Server

Introduction to Temporary Tables in SQL Server
3.9 (77.5%) 8 votes

A temporary table in SQL Server, as the name suggests, is a database table that exists temporarily on the database server. A temporary table stores a subset of data from a normal table for a certain period of time.

Temporary tables are particularly useful when you have a large number of records in a table and you repeatedly need to interact with a small subset of those records. In such cases instead of filtering the data again and again to fetch the subset, you can filter the data once and store it in a temporary table. You can then execute your queries on that temporary table. Temporary tables are stored inside “tempdb” which is a system database. Let’s take a look at how you can use a temporary data in a simple scenario.
