First, use the MFC Application Wizard to generate a dialog box-based application.   Then, register the hotkey in the OnInitDialog member function of the dialog box class. : RegisterHotKey (m_hWnd, 001, MOD_ALT, VK_ESCAPE ); : Global

Editor's note: MFC has done a lot of work for us and it is necessary to learn the detailed process. : // Win32 dialog box. cpp: Defines the entry point for the application. //   # Include "stdafx. h"   // Define the window message Response Function

C ++ -- pointer Review I. Basic Concepts 1. Memory storage Principle If you define a variable in the program, allocate the memory unit to the variable during compilation. The system allocates a certain length of space based on the variable type

In efficient C ++ programming, we can see a good memory pool implementation solution. Here we share it and let's see what's wrong.The Code is as follows:Template Class CMemoryPool{Public:Enum {EXPANSION_SIZE = 32 }; CMemoryPool (unsigned int

I have read a part of Objective C ++ before, but I found that there is no actual programming in the future. So I will study it again and take notes. When you are idle, we often look at these terms and apply them to actual programming.(1) clause 01

Features of member functions being overloaded:(1) the same range (in the same class );(2) The function name is the same;(3) parameters are different;(4) virtual keywords are optional.Override refers to the function of a derived class that overwrites

The pre-processor defines four useful constants for us. Using these four constants, we can provide more information in the error message. They are: _ FILE name _ LINE _ current row number _ TIME _ file Compilation TIME _ DATE on which the file is

This is a kind of number. The remainder of the new number pair formed after the right of any number is 0. For example, 2, No matter what number is placed on the right side of 2, the number is always an even number. Therefore, the remainder of 2 is 0.
