对于VC++6.0 IDE想不用插件直接显示成黑底白字可以手工设置“工具-选择-格式（在最后面）”。我做了个英文版的 vc6-black-ground.reg 的配色方案，您可以用记事本新建 vc6-black-ground.txt 粘贴一下代码到这个txt文本：

Windows Registry Editor Version 5.00

保存后改名成vc6-black-ground.reg。双击运行即可，然后打开VC6.0，一下子就变成VS界面了。
如果你的计算机没有微软雅黑，改成其它字体就行，比如幼圆。可以修改reg文件的"FontFace"="微软雅黑"这行。在VC里面的“工具-选择-格式-源窗口”也可以调整字体和大小。
如果要卸载中英文版本配色就用 vc++6-black-ground-cn-en卸载.reg ，代码如下：

Windows Registry Editor Version 5.00

[-HKEY_CURRENT_USER\SOFTWARE\Microsoft\DevStudio\6.0\Format\Source Window]

中文版的 vc6-black-ground-cn.reg 的配色方案如下：

如果要恢复原始VC6的白底黑字，用命令regedit进入注册表，删除HKEY_CURRENT_USER\SOFTWARE\Microsoft\Devstudio\6.0\Format这个目录，重启VC6即可。
如果您安装了VC++6.0助手（VAX，它支持中文和英文VC6），那么颜色不对可以在VAX中选颜色。
顺便说下给VC++6.0加行号，需要下载一个VC6LineNumberAddin.dll，涉及sn网上下载吧，这里就不提供了。说明书：
VC6.0显示行号的插件，很好很强大的显行号插件，使用VC6.0编程的朋友再也不用烦恼没有行号的编程环境了。
VC显示行号插件使用说明：
1. 如果你的VC安装在C盘，请拷贝文件VC6LineNumberAddin.dll到如下目录：
C:\Program Files\Microsoft Visual Studio\Common\MSDev98\AddIns
或
C:\Program Files (x86)\Microsoft Visual Studio\Common\MSDev98\AddIns
2. 注册
双击VC6LineNumberAddin.reg进行注册。
3. 启用
打开vc6，菜单栏：Tools -> customize -> Add-ins and Macro Files
选中VC6LineNumber Developer Studio Add-in
点击关闭。如果不行，可重启VC++ 6.0
中文版是：工具 ->定制 -> 附加项和宏文件->选中VC6LineNumber Developer Studio Add-in
点击关闭。如果不行，可重启VC++ 6.0。如果遇到中文版没有工具条出来，请用360卸载，重新安装才行。
