The main purpose of my article is to introduce the principles of high quality design for a subset of classes and interfaces. These guidelines should not only ensure that the design and implementation of the class or interface itself has high-quality

In two of Visio development, when publishing drawings, we often need to save the drawings and drawings of the equipment information to the database, the drawing is to save the file to the database in binary, equipment information is to save the

To implement a on-screen keyboard, all keyboard events need to be monitored regardless of whether the form is active or not. So you need a global hook, which is the system-wide hook. What is a hook (hooks) Hooks are a message processing mechanism

The running speed of the software must be within the acceptable range of the user. Generally, improving the speed of those short but frequently used routines can significantly improve the overall speed of the software. To improve speed, of course,

C # simulate MSN form jitter The form jitter is a very interesting thing, let's look at how it works together. is actually generating random numbers, and then changing the coordinates of the top left corner of the form. I use a loop to make it,

Summary: This article provides an overview of how to select the correct policy to overload the user-defined type with the + operator. User-defined types such as: strings, dates, complex numbers, federations, and files often overload the two +

C + + provides a number of powerful mechanisms to achieve high code reuse, so that we can use our own classes as quickly and easily as with built-in types. such as templates, operator overloading, and so on. Templates such as a large production of

The purpose of introducing inline functions is to solve the problem of the efficiency of function calls in programs. A function is a more advanced abstraction. The introduction of it makes the programmer only concerned about function and the use of
