请高手指点呀:怎样删除一个DWG文件
想请教各位大侠一个问题在ARX中怎么来实现,打开和删除一个DWG文件
请举个例子,在这里先谢谢了
AcApDocument* pDoc;
pdoc = acdocmanager->curdocument();
acdocmanager->activatedocument(pdoc, adesk::ktrue);
acdocmanager->closedocument(pdoc);
想用以上代码关闭一个DWG文件,但总会弹出是否保存该文件的对话框,
若将文件保存该怎么用代码来实现,若不保存直接关闭又要怎么实现,还请高手指点呀!在此先谢过了
帮帮忙吧
谢谢了
我也想知道，而且如果在对话框中进行closeDocument的命令时，总要等到对话框结束以后才能关闭？不知道为什么 // (C) Copyright 1998-2002 by Autodesk, Inc.
