为什么上面那个程序不行？？？？

Answer 1

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

Answer 2

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

Answer 3

#pragram comment(lib, "Wininet.lib")

Answer 4

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

Answer 5

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

Answer 6

你的URL写的是不是有问题啊？

Answer 7

HINTERNET hNet = ::InternetOpen("MSDN SurfBear",
                                PRE_CONFIG_INTERNET_ACCESS,
                                NULL,
                                INTERNET_INVALID_PORT_NUMBER,

DWORD dwBytesRead = 0;
BOOL bRead = ::InternetReadFile(hUrlFile,
                                buffer,
                                sizeof(buffer),
