急需帮助@cad二次开发错误!
我在cad命令行里加载dll,能够生成需要的图形.保存!问题出在我全部关闭cad时.cad 出现如图所示情况!.请大侠帮忙一下!谢谢!(虽然下次打开cad都没问题,但是每次都出现这样的对话框,感觉很烦人!希望高手能告知破解的方法!
不胜感激!
附上代码!(主要就是在当前cad 图形中加入圆,加入外部块,文字等)

circle circle; //这个是我们要加入到模型空间的圆
blocktablerecord btr;//要加入圆，我们必须打开模型空间
blocktable bt; //要打开模型空间，我们必须通过块表(blocktable)来访问它

//我们使用一个名为‘transaction’的对象，把函数中有关数据库的操作封装起来

//现在创建圆……请仔细看这些参数——注意创建point3d对象的‘new’和vector3d的静态成员zaxis

//使用当前的空间id来获取块表记录——注意我们是打开它用来写入
btr = (blocktablerecord)trans.getobject(hostapplicationservices.workingdatabase.currentspaceid, openmode.forwrite);
//现在使用btr对象来加入圆
btr.appendentity(circle);
trans.addnewlycreateddbobject(circle, true); //并确定事务处理知道要加入圆！
