数据校验

在数据校验的时候如何屏蔽掉系统的错误信息？  
   
  还有在用到PB中的检验规则定义的时候，好像不起作用？那位高手帮帮忙。多谢了。 问题点数：10、回复次数：1Top

ItemError   event   (DataWindows)  
   
  Occurs   when   a   field   has   been   modified,   the   field   loses   focus   (for   example,   the   user   presses   enter,   tab,   or   an   arrow   key   or   clicks   the   mouse   on   another   field   in   the   DataWindow),   and   the   data   in   the   field   does   not   pass   the   validation   rules   for   its   column.   ItemError   can   also   occur   when   a   value   imported   into   a   DataWindow   control   or   DataStore   does   not   pass   the   validation   rules   for   its   column.  
   
  Return   value    
   
  Set   the   return   code   to   affect   the   outcome   of   the   event:  
   
  0     (Default)   Reject   the   data   value   and   show   an   error   message   box  
  1     Reject   the   data   value   with   no   message   box  
  2     Accept   the   data   value  
  3     Reject   the   data   value   but   allow   focus   to   changeTop
