GetCardData(unsigned char * ucDesCardData,(struct ST_CARD) )<br>函数如上，我在delphi中定义的 <br>type<br>&nbsp; ST_Card=record<br>&nbsp; wTimes:word; //次数<br>&nbsp;end;<br>数据不正确，大侠帮帮忙，在线等待，十万火急，要多少分都可以，只要我积分够

把你的c++原形GetCardData函数和ST_CARD贴出来才能帮你啊!

typedef struct &nbsp;{ <br> WORD wTimes; //次数( WORD wCardType; //标志，为0<br> WORD wCardId; //表号 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;WORD wCodes; //区号 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;WORD wWiteData; //气量<br>} ST_CARD;<br><br>函数名称：GetCardData(unsigned char * ucDesCardData, <br>&nbsp; &nbsp; &nbsp;(struct ST_CARD)*stUndesData )<br><br>在线等待，可以加分
