ODBC 链接

<img src="images/post/smile/dvbbs/em02.gif" />最近查看一个MicroStaion的数据,发现数据中每个要素的属性里都有一个ODBC 数据链接项,搞不明白什么意思(好像是和数据库的链接关系),请大虾指教下链接数值串的含义:<br>
<br>
                ODBC 数据链接<br>
                9007 5E62 0F81 0002<br>
                003F 0000 0000 0000<br>
<br>
请大虾说下数值串的含义吧,多谢了!

<P>是一个数据结构里面的值</P>
<P>头文件里有描述:</P>
