macros for dummies

Excel2003 Tutorial 57, create a Form command button with macros. Demo Animation Operation Steps It's not easy to call macros by running the Macros dialog box, call macros through shortcut keys, and if you can't remember a lot of macros, let's add a button to the Ex

This article mainly introduces the use of macroable macros in Laravel, has a certain reference value, now share to everyone, the need for friends can refer to the definition of Baidu Encyclopedia: Macro in computer science is a kind of title for batch processing. Generally, a macro is a rule or pattern, or syntax substitution, that describes how a particular input (usually a string) is converted to the corresponding output (usually a string) b

When you compile a shader program, Unity defines several preprocessing macros.Target platform SHADER_API_OPENGL-Desktop OpenGL SHADER_API_D3D9-Direct3D 9 SHADER_API_XBOX360-Xbox 360 SHADER_API_PS3-PlayStation 3 SHADER_API_D3D11-Desktop Direct3D 11 SHADER_API_GLES-OpenGL ES 2.0 (desktop or mobile), using the presence of shader_api_mobile to determine.

Word documents need to add a canonical signature, such as name, address, ZIP code, telephone, e-mail, QQ, etc., if each article to add this information, will certainly affect productivity, now we can use the Wrod "macros" to quickly add signature information.Tip: A shortcut key or a mouse click, detailed information on the inscription can appear in the document, this efficiency than slowly an entry, or even copy and paste are much higher, all this tak

MacroOur calculator program, with 1234 corresponding to subtraction, is a bit of a hindrance to people reading. After one months to look at this code may not be able to think of 0123 or 1234, but also to find in the code, if you can represent the four number of arithmetic to take a meaningful alias, a look is to know what corresponds. No problem, use a macro. The following is the fifth edition of our Calculator program://define arithmetic macros#defin

program in or out of the compilation commands, such as # if and #ifdef, and usually converts the excluded statement to a blank line.(3) Macro expansionThe preprocessor expands the macro reference that appears in the source program file into the corresponding macro definition, which is what this article describes as the function of # define, which is done by the preprocessor.The source program processed by the preprocessor differs from the previous source program, where the work performed is pur

1. Hybrid macros. As styles become more and more complex and require repeated use of large sections of styles, using variables cannot achieve our goal. At this time, the mixed macros will be used. When using a hybrid macro, you must first declare a hybrid macro. When declaring a hybrid macro, there are two types: A Mixed Macro without parameters and a Mixed Macro with parameters. 1.1Declaration of mixed

ZZ from:http://blog.csdn.net/musein/article/details/742609==================================================The __init and __exit declarations is special kernel macros designed to tell the kernel to flag thesefunctions for special handling in cases where they is compiled in statically rather than included asparts of modules.The __init declaration allows the kernel to reclaim the space used by initializationfunctions, while the __exit declaration tells

Compilation: assemblyGuess: So this macro is related to the assembly?!Reference: Some of the constant macros are referenced by both C and ASM, while C and ASM differ in the processing of the immediate number symbol . In ASM, directives are adopted to differentiate whether the operands are signed or unsigned, rather than through the operands. and C is through the property of the variable, not through the operator. c If you want to indicate that a cons

expansionThe preprocessor expands the macro reference that appears in the source program file into the corresponding macro definition, which is what this article describes as the function of # define, which is done by the preprocessor.The source program processed by the preprocessor differs from the previous source program, where the work performed is purely a substitution and unwinding, without any computational function, so as long as you can really understand this when learning the # define

Objective:1) output log is a large loss of system performance2) The information that is output is easily intercepted, causing the information to be unsafe.So we're going to cancel all of the logs in the release version (release). It is obviously not a clear choice if you are going to comment out the log one line at a line.So we can use macros to customize the log output.One of the simplest examples:#ifdef debug# define Gclog (FMT, ...) NSLog (FMT), #

string during C program Compilation # Define max (A, B) (a)> (B ))? (A) :( B) 5. Macro limitations 1. Macros cannot access private members of objects. 2. The definition of macros is prone to ambiguity. Example of ambiguity: # Define table_multi (x) (x * X) Table_multi (10) // 100 is returned, which is correct. Table_multi (10 + 10) // The expected result is 400, while the macro call result is (10 + 10*1

Http://www.dotnetperls.com/post-pre-build-macros You need to use post-build and pre-buildMacrosIn Microsoft Visual Studio 2008. You may have two projects that rely on each other but are separate. We can write a macro to copy files from one project to another after the first one is built. This page provides an example of using build macros with a DLL in Visual Studio.

For the original article, see here Macro, a small piece namedCode. InProgramWhen this name is referenced elsewhere, the compiler will automatically replace it with macro content. There are two types of macros. Their differences are mostly manifested in the Code:Object-likeMacros refer to objects, whileFunction-likeMacro refers to function call. You can define any valid identifier as a macro, connectedC LanguageCan also be reserved, because the Prepr

Meanings of commonly used Macros in Visual C ++ MFCAnd_catchand_catch and_catch (exception_class, exception _ object_point_name) Description:Define Code Block, which is used to obtain the additional exception type in the current try block. Use the catch macro to obtain an exception type, and then use the and_catch macro to obtain the subsequent exception handling code. You can access the exception object (if appropriate) and have more messages about t

C/C ++ zhonghong summary CProgramOfSource codeVarious compilation commands can be included. These commands are called preprocessing commands. Although they are not actually part of the C language, they extend the C programming environment. This section describes how to use preprocessing programs and annotations to simplify the program development process and improve the readability of the program.Macros are not part of the C/C ++ language and are pre-processed by the processor before compilation

Document directory Copy attribute name to definition using macros in ER/studio Copy attribute name to definition using macros in ER/studio Recently, when processing the SQL script generated by ER/studio, we found that if the definition is not defined, there will be no table and field comments after the SQL script is generated.Therefore, a macro is written to implement this function. The Code is as follow
