c# - Launching new process from ASP.NET -

-

i'm having hard time c# / asp.net (.net 4) code works fine in development environment, isn't working on production server.

part of code attempts launch new process run lame.exe (to convert .wav file .mp3):

process convert = new process      {        startinfo =        {         filename = appdomain.currentdomain.basedirectory + "bin\\lame.exe",         arguments =  "--quiet -q 5 -b 16 \"" + filepath + "\" " + directory + "\\" +                                                        tempfile,         useshellexecute = false,         redirectstandardinput = true,         redirectstandardoutput = true        }      };   convert.start();  convert.waitforexit();

and works fine on windows 7 development pc. however, on production windows 2008r2 server, doesn't anything: doesn't crash, or throw exceptions, doesn't anything.

i realise caused user permissions, i'm struggling fix issue. having read dozens of articles, of contradict each other, can't figure out do.

all application needs run lame.exe inetpub\site\bin directory , spit out file 1 directory another. i'm sure lame.exe isn't starting: having redirected standardoutput streamreader, don't see being output. , again, no exceptions, or errors, apparently generated.

the application running in it's own app pool, under "applicationpoolidentity". w3 publishing service running under local system, , i've tried ticking "allow service interact desktop".

i've given (temporary) full access rights network service account whole \inetpub\sitedirectory.

does know of ''definitive'' way of getting asp.net under iis7.5 create new process, , credentials and/or rights need use? there easy way see if external process being started, can narrow down apparent lack of permissions biting me?

what john saunders says not creating process inside asp.net thread! recommend having 2nd process running on server follows source directory , converts files in background, see attempting wait result. bad idea halt processing thread until completes -- not belong on production server don't use long-running tasks way, kill scalability.

Line ending issue with Mercurial or Visual Studio -

-
i seem have strange issue caused either visual studio or mercurial. localised single project, i'm guessing in project configuration causing issue. at difficult specify point, when perform action in visual studio, update every line ending in given file, means when @ file in sourcetree, every line has changed. i can replicate using nuget add package dependency; packages.config entirely replaced. if commit changes, including line endings, later same issue occur. workaround have shelve changes , reapply them, whereupon lines written correctly. i'm not sure application blame here. did make mistake of allowing sourcetree change mercurial configuration, issue have fixed, i'm not sure if has persisted. i thought might issue mercurial.ini files or hgrcs don't seem contain untoward. here's mercurial.ini [ui] username = ....
