In C#, a function is a way of packaging code that does something and then returns the value. Unlike in C,C++and some other languages, functions do not exist by themselves. They are part of anobject-orientedapproach to programming. A program to manage spreadsheets might include a sum() fun...
we are going to create a class that is later extended via Blueprints by a designer or programmer. In this class, we are going to create some properties that the designer can set and we are going to derive new values from those
Before I introduce you to the GPU programming performance-optimization technique called “tiling,” remember that in the previous article, you learned about index, extent, array_view, restrict(amp) and parallel_for_each. You’re able to use the C++ AMP API to implement your own data parallel...
IN/OUT 标志传送指令 PUSHF/POPF 这一节主要讨论通用数据的传送指令。 MOV 类指令 MOV 类指令就是将数据从一个位置复制到另一个位置,不做任何变化的指令。 需要注意的是: 源操作数指定的值是一个立即数,存放在寄存器活着内存中 目的操作数指定的是一个位置,寄存器或者内存地址 X86-64 限制,两个操作数都不能...
Uses the SQRT function to return the square root of the value in A1. =TODAY() Returns the current date. =IF(A1>0) Tests the cell A1 to determine if it contains a value greater than 0. Select a cell and start typing In a cell, type an equal sign (=) to start the formula...
(virtual function tables), the array of pointers used to dispatch virtual functions to their runtime-determined implementations. Compiling with -fnortti is a common optimization to disable generating this extra state, which can save on code size as well as compilation times (since ...
An Introduction to Delegates Jeffrey Richter Callback functions are certainly one of the most useful programming mechanisms ever created. The C runtime's qsort function takes a callback function to sort elements within an array. In Windows, callback functions are required for window procedures, hoo...
Nesting level limitsA formula can contain up to eight levels of nested functions. When Function B is used as an argument in Function A, Function B is a second-level function. In the example above for instance, the SUM function is a second-level function becau...
This interface is known as the ATMI interface. It provides function calls to open and close resources, manage transactions, manage typed buffers, and invoke request/response and conversational service calls.Communication ParadigmsThe function calls described in the ATMI reference pages imply a particular...
To create an unmanaged function (non-COM) in the same COM DLL, I first have to define the method and implement it in the unmanaged DLL. Select MSDNCOMServer.cpp and paste the code below at the very end of that file. STDAPI MyNonCOMMethod() { wprintf_s(L"Inside MyNonCOMMetho...
