 Typically, the old C API uses several combinations of char* pointers for data exchange instead of vector or string objects. Such an API will be there for a long time, and if we want to use STLeffectively, we have to coexist with them.Fortunately,

The form is divided into two parts: the client area and the non-client zone (non-client area)The WM_PAINT message, OnPaint () method, GetDC () API functions are all processed by the client area of the form.The title bar is in the non-client area, so

Recently in the GDI part of C #, I tried to write a subtitle control (in fact, it is more appropriate to use a label), but found that the control with GDI to paint the entire control seems not good (should be my level), so I went to the next WIN32

Recently, in a project, the customer requested to display the content in the generated RTF file by page. As he had no idea about this, he also found relevant information on the Internet, in addition, I used my own search on msdn to solve the problem.

Unity SurfaceShader programming started At the beginning of 14 years, I set three goals for myself to achieve this year. One of them was to learn to compile my own Shader and put it into practical project applications. Now, in a twinkling of an eye,

This article is a companion article of C ++ socket web crawler (1). How can I write web crawlers with fewer threads?   Source code: http://files.cnblogs.com/magicsoar/ThreadPoolProject.rar * C ++ 11 is required and compiled in vs2013 Running

Today, my colleague asked me about the image compression algorithm. I think of a project I did about two or three years ago. It contains two compression algorithms: size and quality, and supports JPEG, bmp, and PNG formats. I will post this logic

    Question: give n numbers and ask how many times the number at each position is changed after K transformations. After a transformation, the number at the I position is defined as all met min (abs (I-j), n-abs (I-j ))   Ideas: We will first

The tree array in this question is a little characteristic, that is, the so-called discretization is required. It seems mysterious to start to hear this name, but it is actually very simple. It is to convert the value of an array arr into a group of

1.1 auto-completion (require 'auto-complete) (require 'auto-complete-config) (ac-config_default) auto-completion is a basic plugin. when you input the existed string in a file, emacs will give your some tips. 1.2 yasnippet (require 'yasnippet)

Question: Given n points, m points have directed edges. Divide points into several sets so that any 2 points in each set are not reachable (a set can only store one point) The question must be divided into several sets at least. If no ring exists,

[Link to this article] Http://www.cnblogs.com/hellogiser/p/reservoir-sampling.html The problem originated from Question 10 in programming Pearl Column 12, which is described as follows: How cocould you select one of n objects at random, where you

OJ question: click here ~~ Question Analysis: output the k-th prime number The purpose of posting such a simple question is not pure The basic idea of using the sieve method to calculate the prime number is to arrange the positive integers in a

Interval query, vertex modification, insertion, and deletion. Let's take it as a template first. It's a little frustrating, supplemented, and optimized slowly. # Include # Include # Include # Include # Include

Previously, the original author's code was further encapsulated by using the template class to automatically implement the COM connection point receiver (Sink), and the principle used by the connection point was clarified. During the process of

I recently looked at the Luatinker source code and planned to write a simple library that encapsulates the combination of C ++ and LUA by myself. The results showed that there were more troubles and confusions than I thought. For example: 1)

Tools for large programs -- Exception Handling [continued 1] 4. Re-Throw It is possible that a single catch cannot completely handle an exception. After some corrective actions,CatchIt may be determined that the exception must be in the function

Differences: 1. new/delete is only available in C ++, while a significant difference between new/delete and malloc/free is that new is an object, and call the object constructor to initialize the object. In fact, in all the new operations, there are
