运行到InternetCrackUrl怎么总是出错??

Question

LPURL_COMPONENTS UrlComponents;
CString strTempUrl = "Directory%20_1/1B.htm";
//还原成Directory _1/1B.htm
InternetCrackUrl(strTempUrl,strTempUrl.GetLength(),ICU_DECODE,UrlComponents);//高手们帮我看一下

Answer 1

URL_COMPONENTS UrlComponents;
CString strTempUrl = "Directory%20_1/1B.htm";
//还原成Directory _1/1B.htm
InternetCrackUrl(strTempUrl,strTempUrl.GetLength(),ICU_DECODE,&UrlComponents);

Answer 2

按照MSDN上的说法写成:
URL_COMPONENTS UrlComponents;
CString strTempUrl = "Directory%20_1/1B.htm";
UrlComponents.dwStructSize = sizeof(URL_COMPONENTS);
//还原成Directory _1/1B.htm
InternetCrackUrl(strTempUrl,strTempUrl.GetLength(),ICU_DECODE,&UrlComponents);
最后InternetCrackUrl还是返回错误.
