简单问题，先是一个立体正方形的DX程序。

[心雨楼]

这段代码使用vc6写的
我拿到vs.net下编译通不过，

我新建一个win32空项目,在新建一个cpp文件，内如如下面的代码。
我添加了附加依赖项 C:\DXSDK\LIB\d3dX8.lib
编译如下错误
DXD8TEST fatal error LNK1104: 无法打开文件“libci.lib”
不知道哪里需要这个库？

libci.lib 是旧版本 VC 的 io 库。新版本 VC 中使用的是 libcp.lib。解决办法：在项目属性中设置 /NODEFAULTLIB: libci.lib 然后 ex: libcp.lib 就可以更正旧项目的链接错误。
