函数原型：

BOOL AfxExtractSubString(CString& rString, LPCTSTR lpszFullString, int iSubString, TCHAR chSep = ‘\n’)

参数说明：

rString　　保存输出的子字符串

lpszFullString　　待分割的字符串

iSubString　　提取的子字符串的序号，从0开始。假如你想提取第3段，该参数就输入2

chSep　　用于分割的字符，默认的是’\n’

返回值：分割成功，就返回TRUE；iSubString越界，则返回FALSE

举例说明：

CString szGet;	
CString szText = "var hq_str_sh600736=\"苏州高新,5.33,5.32,5.70,5.85,5.32,5.71,5.72,56939555,323766177,92561,5.71,121300,5.70,57200,5.69,34600,5.68,18600,5.67,130327,5.72,177801,5.73,40999,5.74,194908,5.75,69600,5.76,2011-08-12,15:03:07\";";

AfxExtractSubString(szGet, szText, 1, ',');	//取回 5.33
AfxExtractSubString(szGet, szText, 2, ',');	//取回 5.32
AfxExtractSubString(szGet, szText, 3, ',');	//取回 5.70
//想要取回苏州高新
AfxExtractSubString(szGet, szText, 0, ',');	//先取回var hq_str_sh600736="苏州高新
AfxExtractSubString(szGet, szGet, 1, '\"');	//取回 苏州高新

注意：用于分割的只能是字符，不能是字符串。

多个字符使用_tcstok函数,另外可以使用find函数自己写.

,SystemTimeToFileTime接口计算出错。不知道具体原因。然后Google找到另外一种解决办法就是用utime来修改(修改/访问)时间使用_wutime修改的代码

MSDN documentation states that for files larger than 4 gigabytes,there is the CFileFind::GetLength64() function that returns the size as 64Bit number.But the function just return a wrong 32Bit number. Damn Microsoft!

Solution: write a derived class(CMyFtpFileFind) from CFtpFileFind,and implementing the GetLength64() member function correctly. Replace this derived class with CFtpFileFind.

Reference: http://www.codeproject.com/KB/bugs/getlength64bug.asp.aspx?print=true
Last version: https://gist.github.com/978421

Source code as following text:

class CMyFtpFileFind : public CFtpFileFind
{
public :
CMyFtpFileFind ( CFtpConnection * pConnection , DWORD dwContext = 1 ) : CFtpFileFind ( pConnection , dwContext )
{
}

virtual ~ CMyFtpFileFind () { }

__int64 GetLength64 () const
{
ASSERT ( m_hContext != NULL );
ASSERT_VALID ( this );
unsigned __int64 uRet = 0 ;

if ( m_pFoundInfo != NULL )
{
unsigned __int64 uFileSizeLow = (( LPWIN32_FIND_DATA ) m_pFoundInfo ) -> nFileSizeLow ;
unsigned __int64 uFileSizeHigh = (( LPWIN32_FIND_DATA ) m_pFoundInfo ) -> nFileSizeHigh ;
uRet = uFileSizeLow + ( uFileSizeHigh << 32 );
}

return uRet ;
}

}; // CMyFtpFileFind
