calling GetLeft (), the GetTop () method can retrieve the location of the view. The former returns the left or x coordinate of the view rectangle. The latter returns the coordinates of the top or y axes. Both methods return a position relative to their parent class. For example, when call GetLeft () returns 20 o'clock, this view is located at the right 20 pixels from the left edge of the parent class.In addition, there are some quick methods that are provided to avoid unnecessary computations,
true and accurate as possible. Whether it is divided or not, whether the use of demographic dimension or motivation, personality and other psychological dimensions, should be in the analysis of specific research tasks, based on the necessary preliminary research to determine, so there is no rigid classification pattern. However, at present, some of the existing practice is to engage in a High-profile user classification, engage in persona, play the i
virtual attribute behavior is the same as that of the abstract method.
Use static attributesVirtualThe modifier is incorrect.
UseOverrideModifier attribute declaration. You can override the virtual inheritance attribute in a derived class.

The information contained therein is customer: me; date: Today; place: U-mart; product: Chocolate; quantity: 2; Price: 23.54¥. Customer, date, location

Virtual keywords are used to modify methods, attributes, indexers, or event declarations, and enable them to be overwritten in a derived class.
When a virtual method is called, The runtime type of the object is checked for the override member.
Virtual modifiers cannot be used with static, abstract, private, or override modifiers.

elements of column J in the second matrix, are multiplied and then summed, resulting in the elements of column J of row I of the result matrix.The above description is difficult to understand only once, please combine the examples in the picture carefully.Matrix multiplication First requires that the size of the two matrices participating in the multiplication be "compatible", specifically requiring that the number of columns in the first matrix be the same as the number of rows in the second m
non-red drilling users, it and non-it users, primary users, ordinary users, advanced users, etc. , the common feature of these user classifications is to divide users from one dimension or two dimensions, as in Cooper's about Face 2.0, which refers to two user metrics: the Business domain level (domain knowledge) and the computer skill level, Thus dividing the user into the primary user, the ordinary user, the advanced user, simpler to say this metho

This analysis method is "offline analysis ", low efficiency.To improve data analysis efficiency, OLAP completely breaks the record-based data browsing mode, and separates data into dimensions and measures )":>DimensionIs to observe the data angle, such as the above example of "sales time", "sales location", "product ";>MeasurementIs the spe
OLAP (on-line analysis processing) enables analysts, administrators, or administrators to quickly, consistently, and interactively access information from multiple perspectives, this gives you a better understanding of the data. OLAP is designed to meet decision-making support or specific query and report requirements in multi-dimensional environments. Its core technology is the concept of "dimension. Dimension is a high-level classification from the perspective of observing the objective world.

Some concepts in Mathematics and Computer Science are simple in one or two dimensions but become more complex when extended to arbitrary dimensions. Consider solving differential equations in several dimensions and analyzing the topologyN-Dimen1_hypercube. The former is much more complicated than its one dimen1_
using the multi-dimensional dataset wizard, you can easily define a simple multi-dimensional dataset in SQL Server 2005. This wizard helps you define measurement values and dimensions for cubes. In this wizard, you can define a multi-dimensional dataset based on the data source, or you can define a multi-dimensional dataset without using an existing data source. If you define a cube without using an existing data source, use this wizard to generate an
1. Intention: Separate the abstract part from the implementation part so that they can all change independently.
It is understood that the abstraction and implementation in this sentence do not refer to the implementation of abstract classes and subclasses in OO, but "separating the changes of multiple dimensions in one thing ".
The abstract part in this sentence is separated from the implementation part. You can join the tank and platformimplementati
OverviewBridge mode is a very practical structure design mode, if a class in a software system has two independently changing dimensions, this mode can separate the two dimensions, so that the two can be independently expanded, so that the system more in line with the "single responsibility principle." Unlike a multi-tier inheritance scheme, it designs two independently varying
distance between A and C, but is 10cm of height really equivalent to 10kg of weight? It is therefore problematic to measure the similarity between these samples using he distances.In short, there are two main shortcomings of the He distance: (1) The dimensions of each component (scale), that is, "unit" as the same view. (2) The distribution of each component (expectation, side, etc.) is not considered to be different.(3) MATLAB calculates he distance
