Visual Basic .Net Part of the basis of analysis
Abstract this paper attempts to Visual Basic. Net-depth analysis, and ultimately reached on the basis of further editing and expansion of the purposes of this code.
1. INTRODUCTION
. Net technology is Microsoft's launch of a new concept. "It represents a collection of one environment and can serve as a platform to support next-generation Internet there is a programmable structure." Its purpose is to the Internet as the basis for next-generation operating system, on the Internet to expand the design idea.
. Net is the ultimate goal of allowing users in any place, any time, using any device can access the necessary information, culture and procedures. Users do not need to know where the document, only a request, and then be able to accept the results, the complexity of the background process is transparent to the user's.
. Net framework, including the common language runtime and. Net class libraries. Library is a common language runtime. Net basis, the user can be seen as the common language runtime in the implementation of a code when the management agent, which provides core services, but also the type of enforcement of strict security checks to ensure the security of code running and reliability. In fact, the concept of code management is the basis of the principle of running the Treasury. The objective of the Treasury to run the code as managed code to run the library as the goal of code known as non-managed code. . Net Framework is another major component library, it is a comprehensive object-oriented collection of reusable types, the user can use it to develop include the traditional command-line or graphical user interface applications that are based on ASP.Net to provide innovative applications, including applications.
Based on the latest designer Visual Basic.Net data, you can drive through the user guide to create the code. Designed through the application process by the implementation of event-driven, once the proceedings after the events in accordance with the implementation of the corresponding code, if no incident occurred, the program on the spare, and waiting for the incident, when the user can also start other applications. Therefore, in this programming model, programmers need to consider an event occurred, the system what to do in order to produce the corresponding event procedure code, event code 原文请找腾讯752018766优,文-论~文;网http://www.youerw.com programming; ADO.Net for database access use; to facilitate the conduct of WEB applications. Quoted here are more strict object-oriented features such as packages, inheritance, can be overloaded, and polymorphism and so on, in order to realize object-oriented programming, is an object-oriented programming language.
In this article, I will be the point of view of object-oriented design to analysis and discussion of Visual Basic. Net Data Designer generated code.
2. To build a Windows form and control of
Form the so-called windows of the window in fact, VB.net applications in windows forms is based.
There are many common attributes, the following form to highlight the common attributes.
Name Attributes: form used to obtain or set the name, the application can be invoked through the property to form.
Windows State Attributes: form used to obtain or set the window status.
Text Attributes: the attribute is a string attribute used to set or return in the title bar text.
Width Attributes: form used to obtain or set width.
Height Attributes: form used to obtain or set the height.
Left Attributes: form used to obtain or set the left edge of the x coordinates.
Top Attributes: form used to obtain or set up on the edge of the y coordinates.
Control Box Attribute: used to obtain or set up a value, the value of the instructions in the form of the title bar of the control box is displayed. Value of TRUE will be shown when the control box, a value of FALSE will not show the control box.
Modal Attributes: form used to set whether the display mode for the form. If there are patterns revealed that the form, then a value of TRUE, otherwise FALSE.
Active Control Attributes: set up used to obtain or control the activities of the container control. Form is a container control.1660
