c# - Parsing a formatted string with RegEx or similar -


i have application sends tcp message server, , gets 1 back.

the message gets in format:

0,"120"1,"data field 1"2,"2401"3,"data field 3"1403-1,"multiple occurence 1"1403-2,"multiple occurence 2"99,""

so set of fields concatenated together.
each field has tag, comma, , value - in order.
tag number, value in quotes, comma seperates them.
0,"120"
0 tag, 120 value.

a complete message starts 0 field , ends 99,"" field.

to complicate things, tags have dashes because split more 1 value.
order of numbers not significant.

(for reference, "fedex tagged transaction" message).

so i'm looking decent way of validating have "complete" message (ie has 0 , 99 fields) - because it's tcp message guess have account not having received full message yet.
splitting values need.

the best have come parsing poor regex , cleaning-up afterwards. heart of this: (\d?\d?\d?\d?-?\d?\d,") split it

string s = @"(\d?\d?\d?\d?-?\d?\d,"")"; string[] strarray = regex.split(receiveddata, r);  assert.areequal(14, strarray.length, "array length should 14", since have 7 fields.);  dictionary<string, string> fields = new dictionary<string, string>();  //now put dictionary should easier work array (int = 0; <= strarray.length-2; i+=2) {     fields.add(strarray[i].trim('"').trim(','), strarray[i + 1].trim('"')); }

which doesn't work.
has lot of quotes , commas left over, , doesn't seem particularly well-formed...
i'm not regex can't put need do.

i don't know if best way.

any appreciated.

i suggest use regex.matches rather regex.split. way can iterate on matches, , use capture groups grab data want directly, while still maintaining structure. provided regex should work below in example:

        matchcollection matchlist = regex.matches(receiveddata, @"(?<tag>\d+(?:-\d+)?),""(?<data>.*?)""");         foreach (match match in matchlist)         {             string tag = match.groups["tag"].value;             string data = match.groups["data"].value;         }

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
