VC6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’…
