definition drive patch kb835221 kb888111; 2. restart the computer system; 3. re-enter the soundmax installer, and the program will automatically restart the HD Audio bus program, it is completely normal in the future. Since then, the HD Audio problem has been completely solved !!! [Analysis]: it should be kb835221 kb888111. If the two patch packages do not correctly install the driver for the sound card,
In the previous course we learned some simple data types (integer, the definition and application of the real type, character type, and the definition and application of array (one-dimensional, two-dimensional), which is characterized by defining the storage attribute and range of the type variable when a particular data type is defined. For simple data types, you can define a single variable,You can also d
compiler compiles a program, it compiles only one source file and generates the corresponding intermediate file (for the VC, the. obj file), and then the connector unifies all intermediate files to form an executable file. The problem is that when the compiler compiles the A.cpp file, it discovers the definition statement and defines the variables A and B, but when compiling b.cpp, it discovers the code of A and B, such as a++, and the compiler will e
Generally, an embedded system is a device or system that executes special functions and is controlled by an internal computer. an embedded system cannot use a general-purpose computer and runs solid software.

A Linked list is a common basic data structure. It is a linear table but does not store data in a linear order, instead, it takes O (n) Time to store the Pointer to the next node in each node to access a node with a specific number. the time complexity of the sequence table is O (logn) and O (1. The linked list structure can be used to overcome the disadvantages that the array linked list needs to know the data size in advance. The linked list structure can make full use of the
C-function, c Function Definition 1. C's design principle is to use functions as the component module of the program. 2. A function is a self-contained unit of program code that completes a specific task. A function generally has two functions to execute some actions. A value is returned for the calling program. 3. The advantages of using functions, code reuse, and more modular programs. 4. Generally, the function is regarded as a black box, which pro
The Declaration tells the compiler some information to assist the compiler in syntax analysis and avoid compiler errors. The definition is to tell the compiler to generate some code that will be used by the connector. That is, the Declaration is for compilationThe connector is defined. This description is vague. Why do we have to make a declaration and definition here? This is because C ++ agrees to split t
"unconditional substitution", and the macro only works on the text of the program, its eyes of the world only text (characters), there is no logical operation. Remember to learn C, the teacher told us: "Every sentence after the semicolon"; ", but the macro definition can not add," Asked why it is: "is not, remember on the line! “。 Now you know why: If you add a semicolon, the semicolon becomes part of the macro d
speech: I am a junior, is a little interested in computer, but I've always been vague about the definition and statement of variables, and the first thing I read was this: define--> as int A; this defines a shape variable, and then it says that the definition of a variable can only be one time and the declaration is multiple times. , and then no, I also asked sev
There are two definitions related to machine learning:1) give the computer the research field of learning ability without fixed programming.2) A computer program that can learn from a number of tasks (T) and performance metrics (P), Experience (E). In learning, the performance p of task t can improve experience E with P.Example: Play Checkers GameE= played a lot of checkers games to accumulate experience.T=
In software engineering, requirements analysis refers to all the work that is required to describe the purpose, scope, and definition of a new system when creating a new or changing existing computer system. Requirement analysis is a key process in software engineering. In this process, the system analyst and the software engineer determine the customer's needs. Only when these needs are identified will th
well understood, but it is easy to confuse when using the parameters of Outerheight (), outerwidth (), especially when it is easy to write the default value false to True.Below take the height as an example to write a calculation method of each size, the width calculation method and the same.Innerheight () = "Padding-top" + "height" + "Padding-bottom"Outerheight () =outerheight (false) = "Border-top-width" + "padding-top" + "height" + "Padding-bottom" + " Border-bottom-width "Outerheight (true)
Background Developing mobile H5 Pages Face different resolution of the phone Face different screen size of the phone Visual manuscriptBefore the front-end development, the visual mm will give us a PSD file, called the visual manuscript.For mobile development, in order to achieve the effect of high-definition pages, visual Draft specifications will often follow the following two points:1, first, choose a phone's screen width high

As we mentioned in the previous article, in WMI, classes are used to abstract and define and manage managed resources. So what is a class? The definition of a class can be found in many object-oriented computer textbooks. My understanding is that a class contains a group of independent functional modules, which are composed of data and functions, data is called a class attribute, and the completed function
In the C and C + + languages, an identifier is allowed to represent a string, called a macro, which can be a constant, an expression, a format string, and so on. When compiling preprocessing, all occurrences of the "macro name" in the program are substituted with the string in the macro definition, which is called "macro substitution" or "macro expansion". A macro definition is done by a macro
Original: http://www.cnblogs.com/GavinDai/archive/2011/10/24/2222735.htmlWe are in the program design, always use the definition of variables and the declaration of variables, but sometimes we are not very clear about the concept, know how it is used, but do not know how a thing, the following I will simply introduce their differences are as follows: (Hope my guidance to you benefit)There are two scenarios for declaring a variable:1, one is the need t
