【求助】提取特征的参数??

wflying

我用UG API画了一个长方体，然后想把它的参数提取出来，写入信息窗口，怎么不行呀，请高手指点！下边是我的代码：
  
int CHANGE_cjtq_act_cb ( int dialog_id,
             void * client_data,
             UF_STYLER_item_value_type_p_t callback_data)
{
     /* Make sure User Function is available. */   
     if ( UF_initialize() != 0)  
        return ( UF_UI_CB_CONTINUE_DIALOG );
  //int error=UF_initialize();
  
     /* ---- Enter your callback code here ----- */
  
   {  
   char *blocklen[3]={"1","2","3"};
   double blockorig[3]={0,0,0};
    
   char * size[3];
   tag_t blkobj;
   tag_t blkobj1;
   int i;
   
  UF_MODL_create_block1( UF_NULLSIGN,blockorig,blocklen,[$blkobj)]
    
   UF_MODL_ask_block_parms(blkobj,1,size);
  
     UF_UI_open_listing_window();
   for(i=0;i<3;i++)
   {
     UF_UI_write_listing_window(size);
     UF_UI_write_listing_window("\n");
   }
  
   }
  
     UF_terminate ();
  
    /* Callback acknowledged, do not terminate dialog */
    return (UF_UI_CB_CONTINUE_DIALOG);  
    
    /* or Callback acknowledged, terminate dialog.    */
    /* return ( UF_UI_CB_EXIT_DIALOG );               */
  
}
