WinInet ways to Get the Post, some websites can Get to the source, while others can only Get to the part, or even return bad request, but I don't know what went wrong, ask the great spirit guide, I am a UNICODE programs, can only take part of the code, InternetReadFile (hHttpRequest pbtBuf, 1024, & amp; NCount); Read only once and the second reading, or the content of the last read pbtBuf, nCount into 0. If I put Buf for large enough memory, you can read all the source code, but read the source code is problematic, and visit some sites will not appear this kind of problem, ask the great spirit guide, please! Upset me two days, also did not find problems,
Out of the question, HttpSendRequest call fails, error code is 12150

Is the URL Encode the problem? What do you want to take a look at the website of the encoding format, different site coding format is not the same ~
