Introduction to WPF framework for novice quick learning

This course introduces the WPF (Windows Presentation Foundation) framework, a UI framework specially designed for the Windows platform, and emphasizes its powerful ability in graphics, text and animation rendering, as well as its close integration with DirectX. Compared with traditional Windows Form and MFC frameworks, WPF framework provides better support for hardware acceleration and vector graphics, enabling developers to create more gorgeous interface effects. The course also mentioned NET Framework, as the multi language support of software development platform, emphasizes that WPF is a framework based on data driven rather than event driven, and introduces MVVM (Model View View Model) design pattern in WPF applications, which helps to effectively decouple design and logic code. In addition, the course also covers how to use VS2022 as a development tool and the necessary C # basics.

Visual Studio 2022 installation tutorial (super detailed)

This course aims to guide learners how to install and use Visual Studio 2022 (VS2022), a popular integrated development environment (IDE) that supports C #, C++, Python, JavaScript and other programming languages. It demonstrated different versions of VS2022, including Community Edition, Professional Edition and Enterprise Edition, and emphasized the free availability of Community Edition for students and individual developers. It explains that 64 bit support enables users to handle larger and more complex projects. The official download address was also provided, and the installation process was explained in detail, including component selection and theme settings, as well as the later addition or removal of components. This course is suitable for developers who want to be familiar with the installation and basic use of VS2022, especially those who are interested in C #, C++and Python development.

Daily patrol inspection method of Oracle database

Oracle database managers need to master the importance of daily patrol inspection and its operation process. This includes ensuring the normal operation and backup of the database, checking performance indicators and failure logs (such as ORA errors), verifying the effectiveness of indexes, monitoring the use of tablespace and operating system space, and conducting database recovery tests. These operations can be realized through patrol scripts. Also, pay attention to database performance monitoring combined with system logs. This paper demonstrates the process of using ADDM script for performance analysis, and emphasizes the necessity of handling the tasks assigned by leaders. The content is suitable for database administrators, operation and maintenance engineers, Oracle database experts, database performance tuning personnel, and IT technical support personnel.

Oracle19c Quick Installation Procedure

The video shows the process of installing and configuring the Oracle database in a virtual machine environment, including preparation, installing necessary software packages, creating and configuring database users, and setting relevant permissions. Finally, the command line tool is used to check the start/stop and listening status of the database. The process also involves the modification of configuration files, the setting of character sets, and the concepts of CDB and PDB. The operation aims to improve the efficiency of database installation and configuration and simplify the management process through command line tools. It is suitable for technicians who need to deploy databases in an environment without graphical interfaces.

008_Output h character_REPL_Quotes_Brackets_ What is a function

The video introduces the programming basics, especially the use of the built-in function 'print' and the concept of the interactive programming environment REPL (Read Evaluate Print Loop). In the demonstration, the simple text "hello word" is output to illustrate the use of strings and how to process strings through quotation marks. It also emphasizes how to diagnose and solve problems when encountering errors in coding, such as undefined variables or using wrong characters (such as full width and half width symbols). The audience will also learn about the concept of function parameters and how to view the help documents of functions. The whole video is suitable for beginners to understand basic concepts when learning programming, emphasizing that mistakes are an important part of the learning process, and advocating a positive attitude towards problem solving.
