about the "createdevice()"
about the "createdevice()"
i am seeing the example "singledoc" of the dwgdirect1.13 doc. i write a project named "singledoct"just like the example "singledoc" .the compile is passed,but when run this sentence "return m_pgs->createdevice();",it throw a error that is "unhandle exception in singledoct.exe: oxc00000005 : access violation."
i don't know how to reslove this problem and what the concept of "device" is.
is "device" here the same as the "device" in vc++?
please help me reslove this problem.thankes!
