字符串拆分的问题????

[Novelty]

CString m_str="filename1:a.txt\r\nfilename2:b.txt\r\nfilename3:c.txt\r\n"
希望根据字符串的规则拆分出以下的三个变量:
CString m_filename1="a.txt";
CString m_filename2="b.txt";
CString m_filename3="c.txt";

int count = 0;
int len;
CString m_str = "filename1:a.txt\r\nfilename2:b.txt\r\nfilename3:c.txt\r\n";

CString filename[10];
int left = 0,right = 0;
for(int i = 0; i < m_str.GetLength(); i ++)
{
left = m_str.Find(':',right) + 1;
if(left < i)
break;
right = m_str.Find("\r",left);
len = right - left;
filename[count++] = m_str.Mid(left,len);
i = right;

}
