<br>内容：DDATA是一个变量，里面包含了<BR>long&nbsp;&nbsp;&nbsp;&nbsp; m_TagId;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString&nbsp;&nbsp;&nbsp;&nbsp;m_Number;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString&nbsp;&nbsp;&nbsp;&nbsp;m_UserName;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString&nbsp;&nbsp;&nbsp;&nbsp;m_OrgName;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString&nbsp;&nbsp;&nbsp;&nbsp;m_Tele;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString&nbsp;&nbsp;&nbsp;&nbsp;m_Pos;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString&nbsp;&nbsp;&nbsp;&nbsp;m_Type;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CTime&nbsp;&nbsp;&nbsp;&nbsp;m_RegTime;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString&nbsp;&nbsp; m_EnterBmp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;double&nbsp;&nbsp;&nbsp;&nbsp;m_Standard;<BR>&nbsp;&nbsp;&nbsp;&nbsp;long&nbsp;&nbsp;&nbsp;&nbsp;m_Number;<BR>&nbsp;&nbsp;&nbsp;&nbsp;int&nbsp;&nbsp;IsEnter;<BR>&nbsp;&nbsp;&nbsp;&nbsp;int&nbsp;&nbsp;IsExit;<BR>&nbsp;&nbsp;&nbsp;&nbsp;byte Status;<BR>&nbsp;&nbsp;&nbsp;&nbsp;byte isExist;<BR>元素

<br>内容：定义了DDATA结构，结构中有很多如byte、long、CTime、CString等等的成员，用于记录数据。<BR><BR>至于它有什么意思或者记录什么数据，光这点代码谁也看不出来！
