c++ - Is it possible to sign in and load a user's desktop programmatically from a windows 7 service on the local machine? -

-

the problem: using windows 7 machine display information on monitor. machine hard reach , has no keyboard or mouse attached. after user logs onto machine using remote desktop, logs off, becomes stuck @ "press ctrl+alt+delete" screen , have plug keyboard , mouse sign in user account responsible displaying correct information on monitor.

i developing windows service in c++ looks @ current sessions see when user logs in , out of remote desktop. want have service sign correct user , display user's desktop after user logs out.

right stuck trying find way have service sign user account , display desktop on monitor. there anyway this?

no. can impersonate user, load user's registry hive, , launch processes user's account, in vista , later disallow interactive services, can't interacts user desktop. can ipc (inter-process communication) between service process , running user process, via tcp, named pipes, , other means, if user logged in desktop. can't start user desktop session.

more info: https://stackoverflow.com/search?q=%22windows+7%22+interactive+service

as how around not having keyboard issue ctrl-alt-delete (even though that's not question asked), may able use on-screen keyboard, depending on uac settings.

by way, isn't c++-specific question @ all; can use entire windows api regular old c.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
