[求助]：生成resbuf链表会崩溃，怎么回事

chat_lin

代码如下：
struct resbuf *list;
AcGePoint3d point(100,100,100);
list=acutBuildList(10,point,40,0.0,41,0.0,42,0.0,0);
那位高手能说出为什么吗？

AcGePoint3d是一个类，在acutBuildList函数中的点是一个数组！程序改改就行了。
struct resbuf *list;
ads_point point;
point[X]=1point[Y]=point[Z]=100;
list=acutBuildList(10,point,40,0.0,41,0.0,42,0.0,0);

清楚了
谢谢！这个我怎么没想到啊，真笨啊

其实，AcGePoint3d也可以用，只是必须先调用asSafeArrayPtr() 将其转换成 ads_point 类型的数据入口：

struct resbuf *list;
AcGePoint3d point(100,100,100);
list=acutBuildList(10,point.asSafeArrayPtr()[/COLOR] ,40,0.0,41,0.0,42,0.0,0);

--------------------

AcAxPoint3d::asSafeArrayPtr Function SAFEARRAY *

asSafeArrayPtr() const;

Returns a pointer to a one-dimensional SAFEARRAY of three doubles that contains the x, y, and z coordinates of the point.
