[求助]：看看我这段程序

下面这段程序编译通过，但在CAD运行时出错，显示“Unhandled Excepton c0000005(Access Violation Writing 0x78656e24)at Address 7800DDD3H",请各位帮忙解决，先谢谢了。

程序不能运行，还是运行到哪个地方出错？看到你上面有交互。

另外，既然使用ARX，不推荐你用命令的方法去做，ARX对象方法做这些很容易的，而且效率要更高。

不好意思，初学ARX，完完全全用对象实现感到很困难。
运行到下面时出错：
for(eb2=eb1;eb2!=NULL;eb1=eb2->rbnext)
{
if(eb2->restype==0)
if(strcmp(eb2->resval.rstring,"LINE")!=0)
acutRelRb(eb1);
if(eb2->restype==10)
ads_point_set(eb2->resval.rpoint,p4);
if(eb2->restype==11)
ads_point_set(eb2->resval.rpoint,p5);
acutRelRb(eb1);
}

估计上面代码有问题，但我看不出来。

照猫画虎

你把acutRelRb(eb1);都去了
在for 外加上
