[求助]插入图形出错
[求助]插入图形出错
用下列代码可以成功插入一个ydphb.dwg图，可是关闭图纸的时候就出错。请问什么原因，谢谢
acgematrix3d mat;
mat.settoidentity();
mat.settotranslation(acgevector3d(inpoint[x],inpoint[y],inpoint[z]));
acdbdatabase *pnewdb=new acdbdatabase(adesk::kfalse);
cstring sfilename;
acedfindfile("ydphb.dwg",sfilename.getbuffer());
sfilename.releasebuffer();
es=pnewdb->readdwgfile(sfilename, _sh_denywr,false);
if (es!=acad::eok)
{
acutprintf("\nthe file %s cannot be opend!\n",sfilename);
completeeditorcommand();
acdocmanager->unlockdocument(curdoc());
return;
}
acdbdatabase *pdb;
pdb =acdbhostapplicationservices ()->workingdatabase () ;
pdb->insert(mat, pnewdb);
new了一个东西之后，是不是要有个对应的处理啊？诸如delete之类的东西?
