本帖最后由作者于 2005-11-28 11:41:49 编辑 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

errBoy 发表于 2005-11-25 17:27:00

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

AcApDocument* pDoc;
pdoc = acdocmanager->curdocument(); acdocmanager->activatedocument(pdoc, ...

 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
