DWORD CALLBACK EditStreamCallback(
DWORD dwCookie, // application-defined value
LPBYTE pbBuff, // pointer to a buffer
LONG cb, // number of bytes to read or write
LONG *pcb // pointer to number of bytes transferred
);
在这个回调函数要填写读取的数据到pbBuff中,cb是要读取的字节长度,pcb存放已读取的字节长度,dwCookie用来传递应用程序自定义的值,一般是一个文件句柄,用于读取数据。

调用StreamIn时,CRichEditCtrl控件会连续调用回调函数直到发生以下情况之一:
1. 回调函数返回非零值
2. pcb中的值为0
3. *pcb的值小于cb的值
4. 系统错误,如内存溢出等
5. 读到文件结束符
6. 对单行的CRichEditCtrl控件,读取到回车换行符。

        VC/MFC社区版块或许是CSDN最“古老”的版块了,记忆之中,与CSDN的年龄几乎差不多。随着时间的推移,MFC技术渐渐的偏离了开发主流,若干年之后的今天,当我们面对着微软的这个经典之笔,内心充满着敬意,那些曾经的记忆,可以说代表着二十年前曾经的辉煌……
        向经典致敬,或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天,我们期待着MFC技术能够恢复其曾经的辉煌,或许这个期待会永远成为一种“梦想”,或许一切皆有可能……
        我们希望这个版块可以很好的适配Web时代,期待更好的互联网技术能够使得MFC技术框架得以重现活力,……
