为什么上面那个程序不行？？？？

[bobob]

ALT+F7,link，object/libaray module 加上Wininet.lib

[bobob]

或者#pragram comment(lib, "Dbghelp.lib")

[bobob]

#pragram comment(lib, "Wininet.lib")

[oyljerry]

什么错误
加入lib文件

[ming6424]

不缺库
InternetOpenUrl
是这里出错了！
错误代码是12006

[hjunxu]

ERROR_INTERNET_UNRECOGNIZED_SCHEME
The URL scheme could not be recognized, or is not supported.

[hjunxu]

你的URL写的是不是有问题啊？

HINTERNET hNet = ::InternetOpen("MSDN SurfBear",

::InternetCloseHandle(hNet) ;

有没有人写个完整的C代码出来啊？？？
