RAII-like Error Handling and Resource Management in C
ByEric MaError handling and resource management are pervasive in programs. RAII originated in C++ is great. With RAII, it is much easier to write easy-to-read code that allocats/deallocats resources in the constructor/destructors. By representing a resource with a local object, we are sure that local object’s destructor will release the resource and will not forget to…
MFC程序使用系统风格界面
ByEric MaVC6默认编译出来的程序在XP下Luma风格下运行也是Windows的经典界面, 有损界面的美观与统一. VC2008默认设置下如果不是使用的unicode也是如此. 本文给出使VC6和VC2008可以编译出使用系统界面风格的解决方案. 1. 使VC6编译出使用系统风格的程序 步骤如下: 1) 创建一个.manifest文件的资源. 在res/文件夹下创建一个跟以程序名加.manifest的文件, 如果程序为test.exe, 则创建test.exe.manifest 文件可由此下载: https://www.systutorials.com/t/g/programming/resultcollector.manifest/ 注意要使用utf-8编码保存。 2) 将新定义的资源加入到.rc2文件中, 类型设为24. 打开res/文件夹下的.rc2文件, 在其中加入如下定义: 1 24 MOVEABLE PURE “res/test.exe.manifest” 其中的文件地址按1)步中修改的设置即可. 之后编译即可, 为了使程序界面可能充分利用系统的界面特性, 可以将界面字体设置为TrueType类型的, 利用Windows XP等系统的屏幕字体平滑特性. 2. 使VC2008编译出使用系统风格的程序 在VC2008下就比较简单了, 如果程序字符集使用unicode则默认就是使用系统界面风格的, 如果选择其它的类型, 则编辑下stdafx.h即可. 最后面部分找到这么一段: #ifdef _UNICODE #if defined _M_IX86 #pragma comment(linker,”/manifestdependency:”type=’win32′ name=’Microsoft.Windows.Common-Controls’ version=’6.0.0.0′ processorArchitecture=’x86′ publicKeyToken=’6595b64144ccf1df’ language=’*'””) #elif defined _M_IA64 #pragma comment(linker,”/manifestdependency:”type=’win32’…
Splitting a String by Another String in C++: A Flexible Utility Function
In this post, we will explore a flexible utility function for splitting a string based on a given delimiter using C++ and the standard library. This allows us to break down complex strings into smaller parts that are easier to process and manipulate. The C++ Utility Function to Split a String by Another String Background:…
How to Generate Mixed Source and Assembly List from Source Code using GCC
ByEric MaWhen debugging and optimizing programs, developers sometimes need to generate and investigate into the assembly generated by the compiler. Generating a mixed source and assembly list will help a lot for debugging and optimization. gcc can achieve this by working with the assembler. Generate assembly list mixed with the source code Just add these gcc…

Win32 Programming: Operation on Files
ByEric MaHere, we show some example code on Win32. The code are operations on file on Win32 OSes. The code here uses some MFC classes. Recursively show the files from a path: void Show(const char *folderPath) { CFileFind finder; CString path(folderPath); path += “*.*”; BOOL bWorking = finder.FindFile(path); while (bWorking) { bWorking = finder.FindNextFile(); cout <<…
