vb.net - GetTokenInformation returns invalid SID? -

-

while following this ran problem.

   <dllimport("advapi32.dll", setlasterror:=true)> _ private shared function openprocesstoken(byval processhandle intptr, byval desiredaccess integer, byref tokenhandle intptr) boolean end function  <dllimport("advapi32.dll", setlasterror:=true)> _ private shared function gettokeninformation(tokenhandle intptr, tokeninformationclass token_information_class, tokeninformation intptr, tokeninformationlength uinteger, byref returnlength uinteger) boolean end function   <dllimport("advapi32.dll", setlasterror:=true)> _ private shared function isvalidsid(sid byte()) boolean end function     each p process in process.getprocesses          dim processhandle intptr = openprocess(process_query_limited_information, false, p.id)         if not processhandle = nothing             dim tokenhandle intptr = nothing             dim bool boolean = openprocesstoken(processhandle, token_read, tokenhandle)             if bool = false                 dim win32error string = new win32exception(marshal.getlastwin32error).message                  messagebox.show(win32error)             else                 dim sidlength uinteger = nothing                 dim sidbyte byte() = nothing                  dim somebool boolean = gettokeninformation(tokenhandle, token_information_class.tokenuser, nothing, 0, sidlength)                  if not somebool                     dim win32error string = new win32exception(marshal.getlastwin32error).message                     messagebox.show(win32error)                      ''returns "the data area passed system call small" error.                 end if                  redim sidbyte(35) '' hardcoded '35' because it's i'm getting sidlength.  somebool = gettokeninformation(tokenhandle, token_information_class.tokenuser, sidbyte, sidbyte.length, sidlength)  ''returns true second time.                  if not somebool                     dim win32error string = new win32exception(marshal.getlastwin32error).message                      messagebox.show(win32error)                 end if                  if isvalidsid(sidbyte)                     messagebox.show("valid")                 else                     messagebox.show("not valid")                 end if  ''returns invalid sid. (fails)

the first call gettokeninformation fails it's supposed guess... returning "sidlength" value of 36. second call succeeds , sid byte() gets populated, call "isvalidsid" returns false... , can't figure out why, if sidbytes populated successfully, what's problem?

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
