使用CStdioFile ReadString与WriteString进行文件存储操作

目的：在data.txt（config.ini）中存储各种程序配置信息（文件存储形式）

CString m_write;

char *str;
str = m_write.GetBuffer(m_write.GetLength());//将字符串转换为字符指针形式  
CStdioFile file("data.txt",CFile::modeCreate|CFile::typeText|CFile::modeReadWrite);
file.WriteString(str);
m_write.ReleaseBuffer();
file.Close();

使用空格间隔每行string，使用下列方式，截段字符串，获取信息。

CString x = "abc def ghi jkld";
CString temp,a,b,c,d;
a =x.Left(x.FindOneOf(" "));
temp = x.Mid(x.FindOneOf(" ")+1);
b = temp.Left(temp.FindOneOf(" "));
temp = temp.Mid(temp.FindOneOf(" ")+1);
c = temp.Left(temp.FindOneOf(" "));
temp = temp.Mid(temp.FindOneOf(" ")+1);
temp.TrimLeft();
d= temp;

cout<<"1."<<a<<endl;

cout<<"2."<<b<<endl;

cout<<"3."<<c<<endl;

cout<<"4."<<d<<endl;
