Use of Conditional compilation macros and Conditional compilation macros Jni is often used when writing code in cocos. Sometimes the class instance pointer is used in the c ++ code of jni. 1. define a global variable # If (CC_TARGET_PLATFORM = CC_PLATFORM_ANDROID) GameInstance * gameInstance = nullptr; # endif 2. In the constructor # If (CC_TARGET_PLATFORM = CC_PLATFORM_ANDROID) GameInstance * gameInst

C/C ++I. Standard definition macroThe standard predefined macros are specified by the relevant language standards, so they are available with all compilers that implement those standards. older compilers may not provide all of them. their names all start with double underscores. _ FILE __This macro expands to the name of the current input file, in the form of a C string constant. this is the path by which the preprocessor opened the file, not the shor

You can run macros in several ways. You can always run macros by using the menu commands. You can also run a macro by pressing the Ctrl key, clicking a toolbar button, or clicking an area on an object, graphic, or control, depending on how the macro is run. In addition, you can run macros automatically when you open the workbook. There is a small problem in the r

Macros: macro, preset text substitution mode:A macro is an abstract concept (abstraction) that replaces certain text patterns based on some of the predefined rules of a column, whereas an explanation or compiler automatically replaces this pattern when it encounters a macro. Similarly, Zabbix saves the preset text pattern based on a macro, and replaces it with the text in it when it is called.The built-in {MACRO} does not need to be added $ to referen

You can easily set up double-sided print Word documents in the Word2003 Print dialog box, but there is no setup option for duplex printing in Excle2003. Users can implement double-sided printing Excel2003 tables by editing macro commands in Excel2003. 1. Edit Excel2003 Macros Command The first time you use the macro feature in Excel2003, you need to add a Personal macro workbook (that is, Pernosal.xls), and then use the Visual Basic Editor to edit t

preprocessing Directives The Swift compiler does not contain pre-processors. Instead, it takes advantage of compile-time properties to generate configuration and language features to accomplish the same functionality. Therefore, Swift does not introduce pre-processing instructions. Simple Macro In C and objective-c, you typically use a # define directive that defines a basic constant in swift, which you can use instead of global constants. For example: A global definition of # define Fade_a

.3) loop statements and switch results are not allowed in inline functions. Functions with abnormal interface declarations cannot be declared as inline functions.Let's talk about the differences between macros and functions:1. macros are used to replace simple strings (note that the replacement of strings is not the replacement of other types of parameters), while function parameters are transmitted with da

0.#define MALLOC (n, type) \sizeof(type))1. Macros can be defined like functions, such as:#define MIN (x, y) (xBut in the actual use, only when writing min (), must be parentheses, Min will be as a macro expansion, otherwise do not do any processing.2. If the macro requires parameters, you can not pass, the compiler will give you a warning (macro parameters are not enough), but this will result in an error. As depicted in C + + books, the compiler (pr

Standard C-language preprocessing requires defining some object macros, with the name of each of the predefined macros beginning and ending with one or two underscore characters that cannot be undefined (#undef) or redefined by programmers. The following predefined macro table, I copied it down.__line__ the line number of the current program line, expressed as a decimal integer constant__file__ the current

You can use the macro recorder to record a series of actions to create Macros macro: An action or a set of actions that you can perform to automate tasks. You can record macros in the Visual Basic for Applications programming language. Or in the Visual Basic Editor Visual Basic Editor: An environment for writing new Visual basic for Applications code and procedures, and editing existing code and procedures.

In Word, it's not difficult to learn to create macros, but it's important to delete them on the basis that they're created. Of course, a lot of friends, not even a macro understand, how can you understand the method of deleting macros? Next, is the master introduced the commonly used to delete a single macro method.
