关于readdwgfile的问题
函数：bool creanent::readdwgfile() { acdbdatabase *pdb=new acdbdatabase(adesk::kfalse); cstring acadpath,filepath; getacadpath(acadpath); acadpath = acadpath.left(acadpath.getlength() - 8); //cstring filepath = acadpath + "test.dwg"; filepath="d:\\test01.dwg"; // filepath=lstopenfile(); if(pdb->readdwgfile(filepath,_sh_denyrw)!=acad::eok); { if(filepath.getalloclength()==0) { afxmessagebox(_t("文件不存在")); } else afxmessagebox(_t("文件不能打开")); return false; } acdbblocktable *pblktbl; pdb->getsymboltable(pblktbl, acdb::kforread); acdbblocktablerecord *pblktblrcd; pblktbl->getat(acdb_model_space, pblktblrcd,acdb::kforread); pblktbl->close(); acdbblocktablerecorditerator *pblktblrcditr; pblktblrcd->newiterator(pblktblrcditr); acdbentity *pent; for (pblktblrcditr->start(); !pblktblrcditr->done(); pblktblrcditr->step()) { pblktblrcditr->getentity(pent, acdb::kforread); acutprintf(_t("classname: %s\n"), (pent->isa())->name()); pent->close(); } pblktblrcd->close(); delete pblktblrcditr; delete pdb; } 这个函数基本上是按教材上抄下来的，我用的是vs
