Original: "Programming WPF" translation 7th Chapter 7. Where Did we go?WPF provides a range of high-quality build and compositing services. A set of shape elements supports a variety of drawing foundations. Some brush types are available, and for determining how shapes are drawn, as well as pens, the brush is enlarged to define how the outlines are drawn. Conversions are supported at all levels, making it e

Original: "Programming WPF" translation 6th Chapter 5. Where did we go?WPF provides resource tools that let us apply dynamic and consistent in the user interface. We can store any resource in a resource dictionary and can refer to these resources throughout the application. The style mechanism of WPF relies on resource dictionaries--by setting properties and templates for controls, based on the skin of the

Therefore, it is recommended that you run this command before you commit the code base.2.

is equivalent to opening a channel on a child object that can call the parent object's method directly. This line is put here, just to achieve the completeness of inheritance, is purely an alternative nature.V. Copy inheritanceAbove is the use of prototype objects, implementation of inheritance. We can also change a way of thinking, purely using the "copy" method to achieve inheritance. Simply put, if you copy all the properties and methods of the parent object into the sub-object, can you also

The process control statements of programming language are used to set the order of calculation execution and to establish the logical structure of the program. It can be said that the Process Control statement is the skeleton of the entire program. Fundamentally, the process control is only for the control of the order of execution of the statement, generally need to co

actual I/O operation is not performed until the standard I/O cache is filled. A typical representation of a full buffer is the read and write of a disk file.2, Row bufferIn this case, the real I/O operation is performed when a newline character is encountered in the input and output. At this point, we enter the word Mr. Foo stored in the buffer, and so on when the return hit enter the actual I/O operation. The typical representation is keyboard input data.3, without bufferingWithout buffering,
