[求助]：acedDragGen（）动态拖动问题------实体显示

xcxm0304

我用acedDragGen(ss, "\n添加点:", 0, dragprosess, rpt);实现的动态拖动，并在dragprosess（）函数中修改了选择集（ss）内实体的的数据。问题出现了：

   捕捉关闭状态：当我拖动实体时实体能够显示出来，但当鼠标不动时实体不显示。

   捕捉打开状态：实体正常显示。

我在dragprosess（）函数中加了如下代码：
        acedSSLength(ss,&len);
        for(long j = 0; j < len; j++ )
        {
                acedSSName(ss,j,ent);
                acedRedraw(ent,1);       
        }
       
也不管用，

请大侠指点，多谢了！！

估计是acedRedraw()的参数的问题，必须成对调用。帮助文件中这样解释
acedRedraw() calls must be made in matched pairs. Every call with a mode of 2 must be followed at some point by a call with a mode of 1. Every call with a mode of 3 must be followed at some point by a call with a mode of 4. Mismatched calls such as a call with a mode of 3 followed by a call with a mode of 1 are not allowed. (This is a change from the previous behaviour of this function that was necessary for display performance optimization.)

但是就是不加acedRedraw()也是一样的毛病啊，
如果acedRedraw()运用正确能解决这个问题吗？好象也解决不了。

有个想法：就是模拟捕捉操作，到底捕捉操作后台执行了些什么呢？？？
