source: vbox/trunk/src/VBox/Main/src-client/ConsoleVRDPServer.cpp@ 73037

Last change on this file since 73037 was 73003, checked in by vboxsync, 6 years ago

Main: Use setErrorBoth when we've got a VBox status code handy. (The COM status codes aren't too specfic and this may help us decode error messages and provide an alternative to strstr for API clients. setErrorBoth isn't new, btw.)
