c# - Listen for cmd output and log to file -

-

i'm trying make c# program can listen , output cmd.exe , log file. example, if run exe , runs command in cmd echo "hello", want echo "hello" written in file.

i know need use filesystem, process maybe?

if possible, , appreciated. thanks.

here's quick little example should work. there lot of examples out there, i'll try looking on stackoverflow , post 1 well...

    string cmd_to_run = "dir"; // whatever you'd be...      // set our initial parameters out process     processstartinfo p_info = new processstartinfo();     p_info.filename = "cmd";     p_info.arguments = "/c " + cmd_to_run;     p_info.useshellexecute = false;      // instantiate new process     process p_to_run = new process();     p_to_run.startinfo = p_info;      // wait exit (i chose 120 seconds)     // waiting output here not asynchronous, depending on task may want     p_to_run.start();     p_to_run.waitforexit(120 * 1000);      string output = p_to_run.standardoutput.readtoend();  // here our output

here's process class msdn overview (there's quick example on page): https://msdn.microsoft.com/en-us/library/system.diagnostics.process(v=vs.110).aspx

and here's example dealing calling readtoend() on process: standardoutput.readtoend() hangs

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
