c# - Reading in lines of text from a rich text box -

-

i making small application myself concatenates statements based on text entered couple rich text boxes on form.

one text box may have 10-20 lines of text, , each line own separate entry, need able read text line-by-line.

however, when researching wpfs, have seen 1 statement on net in regards reading text , reading content of box start finish. somehow loop through or separate line-by-line.

according msdn, extract text wpf rich text box string, need use:

string stringfromrichtextbox(richtextbox rtb) {     textrange textrange = new textrange(       // textpointer start of content in richtextbox.       rtb.document.contentstart,        // textpointer end of content in richtextbox.       rtb.document.contentend     );      // text property on textrange object returns string      // representing plain text content of textrange.      return textrange.text; }

however, if @ rich text box, see text inside list of values, instance, 1 box may below:

000423523  324  93489290099  823342342  0003242342  44400298889

i want able read values line line within richtextbox, in wpf, there doesn't seem richtextbox1.lines option.

you can use string.split() method split richtextbox text line-break , exclude empty lines result set, example :

string[] lines =          stringfromrichtextbox(rtb).split(new[]{environment.newline}                                           , stringsplitoptions.removeemptyentries);  foreach (var line in lines) {     messagebox.show(line); }

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...
