Many people have heard of this, but not many use it in their code. Meanwhile, no serious programs with client-server architecture will do without asynchronous programming. Exchange of data with the database, the interaction of the client and the server - this takes time, which can be occupied by other processes instead of waiting. When the operation is executed synchronously, the thread is blocked by another thread. And we have to wait for the implementation of this second process to return control to the first one. This causes unnecessary waste of resources, because a stream with a single task can wait for a long time to respond. From a database, for example, or a web service. And if temporary resources can save multi-threading (the benefit of modern processors allows it), then memory resources will not save it. After all, in fact, multi-threading is also synchronous execution of operations. Just there are few of them. The real solution is to use asynchronou ...

For more than half a century used barcodes. But this popularity they received during the database development. Barcodes allows you to quickly identify the goods and to find information about it in the database. However, today's two-dimensional bar codes can contain all the information about the product inside. In the traditional sense bar code - a set of characters or lines arranged in a certain order according to the standard. Classic bar codes are a series of vertical lines of varying thickness. The specific order and line size allows to encode characters. Two-dimensional barcodes typically take a square or rectangular area and are composed of pixels, and combinations thereof. These codes allow you to encode more information than linear. In addition to characters can be encoded binary code. Linear bar codes are used mainly in trade, logistics and inventory control, whereas the two-dimensional - in transport networks, government documents, identity car ...

Interactive reports allow users to interact with them. For example, a report can contain hyperlinks, bookmarks and an outline. By clicking on the section title in the content you move to a bookmark in the desired location of your report. These reports are often used in catalogs. Let us create an interactive report for the Web. For this, we need a report template and a web application. We can begin with the report. Its template will consist of two pages - a content and a data page. For example, I used a database of "nwind.xml FastReport.Net" delivery. So, we use a table "Categories and Products".
