source: vbox/trunk/src/VBox/Main/HostImpl.cpp@ 26768

Last change on this file since 26768 was 26753, checked in by vboxsync, 15 years ago

Main: Bstr makeover (third attempt) -- make Bstr(NULL) and Bstr() behave the same; resulting cleanup; make some more internal methods use Utf8Str instead of Bstr; fix a lot of CheckComArgNotNull??() usage
