First, let's vomit about the weather in Hangzhou. It's so hot! Although no sister has been dating me, it is also annoying to stay in the big nest! Next to C # Basic TypesType and member Basics In C #, multiple members can be defined within a type: constants, fields, instance constructors, and type Constructors (static constructors), methods, Operator overloading, conversion operators, attributes, events, types. Type visibilityYesPublicAndInternal(Default) two types: the type defined by the forme

Document directory Font Layout Color This is the second part of a list apart classical technology essay a Dao of web design. Based on the first part, it describes how to achieve elasticity in terms of font, font size, layout, and color, adaptive Web design. Finally, the author points out that web, as a new media, should be quickly influenced by printed media to realize its mission.Solution "The name is also available, and the day is approaching. Never stops. The greatest truths are in the

applications that have implemented Android accessibility. When you use a view-type UI element or a subclass of view in the SDK or support library, you do not need to implement accessibility support, because these classes are already done for you.However, some applications use custom UI elements to provide a richer user experience. These elements do not provide automatic

Master three garbage algorithms, seven garbage collectors, and learn what garbage collection algorithms are used for each garbage collector, as well as knowledge points about SafePoint.garbage Collection Algorithm1. Tag-purge algorithm (mark-sweep)tags (such as the accessibility algorithm) are all objects that need to be recycled, and all tagged objects are reclaimed after the tag is marked.Disadvantage: The labeling and purging process is inefficient

designs. Text and content is very important, borrow by the font, typesetting, picture collocation to reasonably present, it is not 1+1=2 so simple. 　　8, app built-in Blur effect It is also one of the design trends to enhance the visual usability of the app by using background blur and translucent effects. Compared to the solid color background, users tend to use the picture, although improved personalization, but the background layer above the icon, the control can not be clearly

complete the form. Make sure that the form name meets people's expectations and succinctly explain the purpose of each form. If the form needs time or query information to fill out, you can use the start page to set people's expectations. From beginning to end adopt clear browsing Line and effective visual step to guide people, ensure that the clear completion path. For mission-critical forms, such as billing forms or registration forms, you should remove distractions and any links or conte

recycled by GC?" "The question is a little bit of an angle:" How to tell if an object is dead and give it a ' death ' tag? ”First, we introduce two algorithms to "sentence the death penalty" to the object: Reference counting algorithm Accessibility analysis algorithm Reference counting algorithm (Reference counting)Principle: When creating an object, add a "reference counter"to each object, and the value of the counter is incremente

rows are indented to the width of the circle radius size, such a layout causes, the cat theoretically can have 6 walking directions (only one step at a time), is left, upper left, upper right, right, lower right, lower left, such as the circle of these positions as a roadblock, the corresponding direction is not passable. If these six neighbors have five roadblocks, then of course it is good to choose the line, the remaining one is the only way out, but obviously the situation is not so simple

whether the object is alive, garbage collection and other algorithms, in which the object recovery algorithm is based on the accessibility analysis algorithm, garbage collected at present, the JVM manufacturers are widely used in the generation of collection algorithm. This is the main description of the next generation of collection algorithm process.The core idea of the generational collection algorithm is to divide the memory area into the life cy

to call DLLs with return value parameters, such as GetUserName (), Gettextface (), and so on in Win32API. In Visual Basic, a directive shell that executes an external program is provided, in the form of: Shell "command column" If you can match Rundll32.exe with a good shell command, makes your VB program have an effect that is difficult or impossible to implement in other ways: Still, for example, the traditional method requires you to create a module in the VB project, and then write the WI

The title of the content page is not said here, because the title of each article is different, and the weight of the content page is relatively low, is generally set title for the content title + column name + site name. The title of the homepage is the key, you want to let the search engine know what your site is doing, you must first write your title. General search engine will be the weight of the title from left to right to divide the weight, the more on the left keyword ranking the better

counting to manage memory. The algorithm of accessibility analysis The basic idea of this algorithm is to use a series of objects called "GC Roots" as the starting point, starting from these nodes downward search, the search through the path referred to as the reference chain (Reference Chain), when an object to the GC Roots without any reference chain (in the words of graph theory, is to prove that this object is not available when roots from GC t

Sprite is the first problem that causes headaches. In most cases, when a sprite is created and encoded, it is rarely altered or affected by the ongoing maintenance of the Web site. If you feel sprite maintenance is not a problem, then perhaps using a large sprite is the best option. Not all pictures are backgroundAnother reason for not advocating the misuse of CSS sprite is that it can cause developers to use background images incorrectly. Experienced developers consider

Inheritance 3, restrictions on the use of accessibility levels in inheritance When declaring a type, it is most important to see whether the type must have at least the same accessibility as other members or types. For example, a direct base class must have at least the same accessibility as a derived class. The following declaration will cause a compiler error

referenced object has been added to the reference queue to check whether the referenced object is to be recycled. If the program finds that a virtual reference has been added to the reference queue, it can take necessary action before the memory of the referenced object is recycled.2. Object accessibility judgmentIn many cases, an object is not directly referenced from the root set, but is referenced by other objects or even several objects at the sa

protected member inherited from the base class, you can also access the protected member of an object of this type, or access the protected member of the object of the derived class. Protected internal (or internal protected) modifies the Member or nested type of the class, which is available in the assembly or type that defines it or in the derived class. It means "access scope is limited to this AssemblyOrThe types derived from the classes it belongs ". This statement is hard to understand

encapulation ): The following describes how to combine data and methods. method and data: two important features of encapsulation: 1. place the required data and methods in the same scope. 2. pay attention to the accessibility of data and methods. traditional procedural programming languages, such as C language, include a lot of data and functions. Each function can access part of the data, for small Programs , data and functions can work we

# compiler defaults to setting the visibility of the type to internal if you do not explicitly specify the visibility of the type.Friend AssemblyWe want the TeamA assembly to have a way to define its tool type as internal, while still allowing the team to teamb access to those types. The CLR and C # provide support in this regard through friend assemblies (friend assembly). If you want to include code in one assembly, and you perform unit tests on internal types in another assembly, the friend
