You can use Word macro commands to increase your productivity when you edit a document using Word. By default, the security setting for Word macros is high, and macros are automatically disabled when you run the Word Macro command. If you set the Word macro security to Medium, the Word Macro Security warning dialog box
For security reasons, many people add passwords to Office documents and, for memory purposes, may use the same password for all Office documents. However, it is cumbersome to repeat the process of document encryption every new document is edited. Here's a good way to automatically add a unified password to all of the specified Office documents, and we'll take word 2007 for example.
STEP1: First click the "view → macro → record
A macro definition can contain two operators: # And ##.
# The operator converts a macro parameter to a string literal. It can only appear in the replacement list of macros with parameters. # Operators have a lot of usage. Here we will only discuss one of them.
Suppose we decided to use the PRINT_INT macro as a convenient method during the debugging process to ou

In some cases, you may want to perform one or more operations in a macro only when the specified condition is true. For example, if a macro is used to verify data in a form, the correspondin
These two days a little bit of boost preprocessor library, found that the boost of the crazy people to use a variety of artifice to define a variety of data types and structure, but also in the above definition of subtraction and so on various operations, in the process of rapid browsing, but also targeted the very familiar with the various macro names: list,Cons,fold_left, Fold_right, estimates that these people have moved a lot of the features of fu

Write a good C language. A beautiful macro definition is very important. Using a macro definition can prevent errors, improve portability, readability, and convenience. The following lists some mature software commonly used macro definitions ......
1. prevent a header file from being re
, the advantage of this method is that you can print the expression content in a unified way. Similarly, the following macro can be defined to print the values of other expressions:
# Define printc (expr) printf ("
# Define printf (expr) printf ("
# Define printd (expr) printf ("
In the GCC compiler, two string constants can be connected to a new string. Strings are equivalent as follows:
"123456" and "123" 456"
Because # expr is essentially a string,

Processing Operator, which can convert the language symbol into a string. For example If X is a macro parameter, # X can convert the parameter name into a corresponding string. This process is call
In C ++ programming, functions (including inline functions) are generally in lower case, while macro-defined "functions" (macros with parameters) are often in upper case.
The above sentence seems common, but failing to follow this sentence can easily lead to unexpected errors! Today, we will record a typical case:
Because inline functions are very similar to macros, they are performed before the program runs. They both replace expressions with the fun
In C + + development often used in the definition of macro use "#" or "# #", the following is a simple description of the use of two symbols:Define in the # is to use the argument after the # as a symbol, simply to connect it as a string, # #连接前后2个符号, the define definition in the beginning of the "#" macro substitution is not expanded, the macro beginning with th
When tuple is used in Erlang, the order and quantity of data items are determined. Once the order of data items is adjusted or the field is increased or decreased, badmatch is easy to appear.
At the same time, if some constants are hard-coded into the Code, once the value changes, it is difficult to replace them with new ones reliably.
The corresponding solutions in Erlang are as follows:Record macro
Record
In the code, we create a record:-record (man
The _ inline keyword has been compiled and tested using keil4 arm. The difference between macro definition and inline function is verified.
Both macro-defined and inline functions do not generate code segments, and the program runs without the parameter pressure stack overhead.
The Inline Function checks the validity of the called parameter, and can also convert the parameter type.
I. The Inlin
In some cases, you may want to perform one or more operations in a macro only when the specified condition is true. For example, if a macro is used to verify data in a form, the corresponding information may be displayed to respond to certain input values of the record, and the other information to respond to different values. In this case, you can use conditions to control the
1. When a function is called, The Program must jump to the memory address space of the called function, then run the Code of the called function. After the called function is executed, the program returns to the previous position to continue execution. In this case, you need to save the on-site address and remember the executed address before the program jump, recover the on-site address after the switch back, and continue the execution according to the original saved address. in this way,

Many experts like to use the "macro" command to improve office productivity. However, when you use macros in a Microsoft Office program, a macro security warning pops up, especially when you make a personal resume table, you often need to use a macro, and each time you open it, it makes the user feel more troublesome. If you set the security level of the
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
