Special Symbol #, # #(1) #　When you put a # Before of argument in a preprocessor macro, the preprocessor turns that argument into a character array.Using a # in front of a parameter in a macro, the preprocessor converts this argument to an array of characters　Simplified understanding: #是 The meaning of "string", which appears in the macro definition # is to conve

Summer, is a "virus" season, computer viruses are no exception, especially the risk factor is very large Doc virus (virus macro virus) is the use of IE browser access to the network on the Doc page, will also be inexplicably to "black" a. So what is doc exactly a virus ah, it is how black their own baby computer it? Now let's take a look at what the doc virus looks like. Macro virus, it is a special virus

Generally, there are not many built-in macro packages for software such as texlive installed in Linux, and many macro packages have been installed several years ago, in this way, it is often possible to compile the tex files on the Internet in the near future ~ Of course, you can put the macro package on the Internet directly to the tex file directory, but it is

In this case, "macro" is the essence of Excel. How can we record a macro?Next, we will record a macro with the title "center across columns" as an example to see the specific recording process:1. Run the "tool rarr; macro rarr; record new macro&quo

_ IO, _ ior, _ Iow, _ IOWR macro usage and AnalysisIn the driver, the parameter cmd (IOCTL) transmitted by the ioctl () function is the value that the application uses to differentiate the content requested by the device driver. In addition to distinguishing numbers, CMD also contains several types of information that can be useful for processing. CMD is 32-bit in size and consists of four fields: Bit31 ~ Bit30 two-bit is the "differential read/write

6. The instructions for macro actions are not required when you use macros, but you can make macros easier to understand and maintain. You cannot use SQL expressions in the Criteria column of a macro. Typically, the direct execution of a macro is just a test. You can either attach a macro to a form, report, or control

In some cases, you might want to perform one or more actions in a macro only if a specific condition is true. For example, if you use a macro to validate data in a form, you might want to display the appropriate information to respond to some of the record's input values and another to respond to different values. In this case, you can use conditions to control the process of the

Obtain a digital certificate for signing From a commercial certification authority (CA), a certification authority (CA): A business organization that issues digital certificates, tracks people who are issued certificates, signs certificates to verify their validity, and tracks certificates that have been revoked or expired. Or obtain a digital certificate from an internal security administrator or information technology (IT) professional. To learn more about the certification authority that pr

Macro virus mainly in Office software office in the presence of the vast number of users caused a large loss. Use the following three strokes to stay away from macro viruses (this article takes word for example). First trick: Set macro security Level Open Word and select the tools → options → security → macro securit

A classic example. The classic example of using preprocessing and macro definitions is to add a header file to prevent the header file from being compiled two times. Imagine this situation, there is a file headerfile.h it is included in the Headerfile1.h, and also included in the Headerfile2.h, there is now a CPP file, Implement.cpp contains Headerfile1.h and headerfile2.h: #include “headerfile1.h” #include “headerfile2.h” Suppose a global variable

For a complete description of macros and inline functions, see Http://wenku.baidu.com/view/dbf9051c59eef8c75fbfb39f.html This article from http://hi.baidu.com/liugang585570/blog/item/83fa38f9c9d8fd04d8f9fd04.html Before introducing inline functions, it is necessary to introduce preprocessing macros. The functions of inline functions are similar to those of preprocessing macros. We believe that we have used preprocessing macros. We often define some macros, such # Define table_comp (

Macro usage, usePreface Macros play a major role in C/C ++. Keywords Several Functions of macros 1. Define Constants 2. Define an expression 3.

Define an expression #define MAX(a, b) (a>b?a:b) 3. Simplify tedious

SolidWorks two times development -01-record a macro First step: We need to record a macro ourselves and then see what code the program produces. That's what I did when I was learning Excel. Just, SolidWorks to be more complex, directly recorded macros can not be used, need to make some adjustments. In the absence of experience we'd better follow the advice below. Edit or Debug SolidWorks

This article only provides an idea, a kind of personal experience, designed to use a very vulgar and relatively grounded way, prompting cainiao, why, and how to introduce debug Macros in C language programs, develop and maintain good habits. Asked about debugging during the interview, I said: Early printf, later gdb, Q: How does printf work? Directly change the program? Answer: Yes ~! He didn't mention it. I also know that the debug macro should be u
