The Matrix object in FastReport .NET performs typical tasks for displaying summary tables very well. But, when the tasks are not standard, only the report script will help us. It is in the script itself you can implement almost any requirement. As you know, the matrix has a built-in function to display totals by fields and columns. Usually, the total in the summary table is the amount. However, what if you want a total with your own calculation formula. And if you want to display totals selectively for certain columns? To do all this you need to disable the standard totals and create your own column, in which your total will be calculated. But, if you still use the standard totals, then you need to use the AfterTotals matrix event to make their values also appear in the user total. It will happen after the construction of the matrix with all the standard results, so that all the data will be at our disposal. This event does not allow you to add and modify data to mat ...

RFID tags are a modern way to ID products, quickly replacing barcodes. What makes RFID tags different is they use radio signals. This lets you scan large quantities of items fast, saving a bunch of time. RFID tags are also used to identify employees within companies. In this article, we'll check out how RFID tags work with the new TfrxDeviceCommand object in FastReport VCL.     Features of RFID Structure The structure of an RFID tag consists of four data banks: Reserved Bank: Contains two passwords: access password and kill password. The first password allows management of access to specific banks or parts of the tag's memory. The second password is used for permanently disabling the tag or its reusability (if such a function is supported). Each password has a length ...

The FastReport. Core Report Generator is designed to work with the popular .Net Core framework. He gained even more popularity thanks to the compatibility with trend web frameworks and libraries such as Angular, React, Vue. Therefore, many FastReport users would like to use reports in their Web applications written in the above libraries. In another article we have already considered how to display reports in a single-paged application based on Angular. Now let's look at the example of using FR. Core in the application on ReactJS. To work with the React library, you need to install the Node JS program platform, which allows you to run JavaScript code on the server side. Also, with it will be installed Package Manager NPM, which allows you to install various Java Script packages that you need for development. Next, you need the .Net Core SDK 2.0. But if you are developing on MS Visual Studio 2017, you have already installed this SDK. ...

Before the 2024.1 update, to add a row or column, you had to look for the desired property in the properties panel and set the desired value. If you wanted to insert a row or column other than at the end of the table, you had to transfer all the cell values manually. In addition, to transfer values, it was necessary to open the editor, copy the value, and paste it through the same editor of another cell. To resolve these issues and make working with TableObject easier, we have added several changes to the designer ...

We are proud to present our speaker at one of the biggest .NET conferences in Europe - Basta!  Our team lead of cloud development Vitaliy will talk about Load balancing with Rabbit MQ. Here's the synopsis of his talk:  One of the most popular solutions for load balancing is message queues. How to distribute the load evenly among users so that no one is left out? In this session you will learn about developing a distribution system on .NET 6 using Rabbit MQ queues, dynamically adding new users, and comparing it with prioritized queues. Vitaly is a graduate of the Faculty of Mathematics, Mechanics & Co ...
