Excel Animation tutorial: Calling Macros with a form

It is not convenient to invoke macros by running the Macros dialog box, call macros through shortcut keys, and if you can't remember the macros, add a button. If the macro is valid only for the current workbook document, I recommend that you add a form command button to the workbook document to invoke the macro: 1. E

Analysis of the Linux kernel container_of macros in a comprehensible instance

->member) *__mptr = (PTR);" means declaring a pointer constant *__mptr the same type as member, and initializing it to PTR. "(Type *) ((char *) __mptr-offsetof (type,member))," means that the address of the __mptr is subtracted from the offset of member in the struct and converted to a type pointer. In fact, the pointer is the entry address of member. Here is a new example of my previous online example, which I hope will help the reader:#include /* * The CONTAINER_OF and Offsetof

Office 2013 for Windows RT will not support macros and VBA

However, this version has been decided to cancel a number of functions, including macros, Third-party add-ins, and VBA support are discarded, and the reason for this decision is not to affect the battery endurance and reli

Special character references for SAS macros

From:http://blog.chinaunix.net/uid-675476-id-2076827.html In SAS macros, strings are enclosed in double quotation marks, but if a string contains special characters such as double quotes or a percent semicolon, a single quotation mark is used to escape the special characters in the string. Like what:%let test = ' A ' is the first character! '; However, if the string contains single quotes, the above method is invalidated. So more generally, SAS provi

Misunderstood C ++-templates and macros

Templates and macrosSome days ago, when the Forum was hitting a storm, someone came up with the conclusion that the template is essentially a macro. As a result, you have had a good debate. I originally wanted to join the debate, but I thought everyone's remarks had covered my ideas, so I did it.Although I did not participate in the discussion, the question "What is the relationship between templates and Macros?" is always on my mind. Every time I rel

MacroA major role is to automatically generate code for us. If the template can generate various types of code (type replacement) for us ),In fact, macros can generate new Code (replaceme

Usage and Analysis of _ IO, _ ior, _ Iow, and _ IOWR Macros in Linux kernel drivers

| _ ioc_write (bidirectional ).The kernel defines the _ IO (), _ ior (), Iow (), and _ IOWR () macros to help generate the above cmd. The following describes the implementation of _ IO (). Others are similar: You can see the definition of _ IO () in ASM-generic/IOCTL. h.: # DEFINE _ IO (type, NR) _ IOC (_ ioc_none, (type), (NR), 0) Let's look at the definition of _ IOC ().: # DEFINE _ IOC (Dir, type, NR, size )\(DIR) (Type) (NR) (Size) It can be see

Parsing C-function macros

description in section 6.10.3.1 of the standard is still clear, and it writes as follows: after the arguments for the invocation of a function-like macro have been identified, argument substitution takes place. A parameter in the replacement list, unless preceded by a # Or # preprocessing token or followed by a ## preprocessing token (see below), is replaced by the corresponding argument after all macros contained therein have been expande

3 ide tools macros that are useful for VC

I wrote the following three, which has a good effect and can greatly prolong the service life of the keybo

Description of commonly used Macros in MFC

If delcare_dynamic and implement_dynamic macros are used as described, you can use the runtime_class macro and cobject: iskindof function to determine the object class during running time. If declare_dynamic is included in the class definition, implemetn_dynamic must be included in the class tool. Declare_dyncreateDec

C ++ rtti: Two macros are used to create an object based on the object name"

1. Question: C ++ rtti lacks some runtime information and cannot directly create an object based on the object name. To achieve serialization, MFC constructs its own rtti information from the ground up and defines a set of macros. For details, refer to the implementation of the following classes and Macros in the MFC source generation:Cruntimeclass, cobject, declare_dynamic, implement_dynamic 2. Requirement
