i working on program name of file input in command line. need check if input given character "-" , work file according result, not quite sure how it. method have tried, seemed logically make sense, of checking if argv[1] == "-"; always returns zero, when write "-" in command input. can do? you need write strcmp(argv[1],"a")==0; in example, compared 2 pointers , not 2 strings. when compiling, compiler declares "a" somewhere in memory , subsitute in compile time memory address. since argv[1] can't sit on same byte (temporary) "a" , result false. need iterate on 2 strings , iterativly compare each character. strcmp compares 2 strings , return 0 if equale in exact manner. for more info on strcmp : http://www.cplusplus.com/reference/cstring/strcmp/ in order handle multiple characters, can place few if-else's : if (strcmp(argv[1],"-")==0){ minus_character_handling_function(); } else

i'm attempting read file , process in both c# , ironpython, i'm running slight problem. when read file in either language, byte array that's almost identical, not quite. for instance, array has 1552 bytes. they're same except 1 thing. time value "10" appears in python implementation, value "13" appears in c# implementation. aside that, other bytes same. here's i'm doing bytes: python: f = open('c:\myfile.blah') contents = f.read() bytes = bytearray(contents, 'cp1252') c#: var bytes = file.readallbytes(@"c:\myfile.blah"); perhaps i'm choosing wrong encoding? though wouldn't think so, since python implementation behaves expect , processes file successfully. any idea what's going on here?

the title pretty says all. 1 of used used folders in fish terminal became highlighted in yellow. of it's sub folders highlighted in yellow too. not sure happened. it's on mac yosemite fish shell highlighted directories yellow because directory's permissions set everyone can read, write, , execute . essentially fish shell warning directory has least restrictive permissions in case weren't aware. for example, in screenshot: if change permissions directory "oranges" can read+write+execute ( chmod 777 oranges/ ), can see fish shell adds yellow highlight. when change permissions more restrictive ( chmod 775 /oranges ), directory "orange" no longer highlighted. here's good explanation of file permissions , command chmod more detail.

update: i've added sample project testing, see @ bottom of post. original question: i've got nswindow , change background when other parameters change. the window background gradient i'm drawing overriding drawrect in subclass of window's view. class mainwindowview: nsview { override func drawrect(dirtyrect: nsrect) { var rect = dirtyrect let gradient = nsgradient(startingcolor: backgroundcolor, endingcolor: darkerbackgroundcolor) gradient.drawinrect(rect, relativecenterposition: nspoint(x: 0, y: 0)) super.drawrect(rect) } } and i've got 2 nstextfield s on window. the nstextfield s both set drawsbackground = false in awakefromnib , set borderless in ib. i'm not using nsattributedstring s here, changing stringvalue of nstextfields, , of course textcolor . everything working... except sometimes , text fields have unexpected dark semi-transparent background. (it's hard see on screens it

i'm trying embed queries variables in class. like so: class foobar{ public $bar; } $result = array(); $db = mysqli_connect("127.0.0.1", "foo", "foo", "farm"); $sql = "select * `lot`;"; $result = mysqli_query($db, $sql); while($row = mysqli_fetch_assoc($result)){ $foo = new foobar; $foo->$bar = $row["cow"]; array_push($result, $foo); } but when print array using print_r($result) , i'm getting output: array( ) i hoping see objects stored in array. where did go wrong? should doing? you're reusing $result variable. it's an array reuse mysqli resource. also $foo->$bar should $foo->bar . class foobar{ public $bar; } $result = array(); $db = mysqli_connect("127.0.0.1", "foo", "foo", "farm"); $sql = "select * `lot`;"; $query_result = mysqli_query

i'm working oracle database, i'm wondering if there way find rows contains value in column. example let's consider table: weather city state high low phoenix arizona 105 90 tucson arizona 101 92 flagstaff arizona 88 69 san diego california 77 60 albuquerque new mexico 80 72 basically (i know it's not possible), this: select * weather * '%f%' and give me rows flagstaff arizona 88 69 san diego california 77 60 i on java side, querying rows resultset dynamically search given value in column , add row. problem table contains millions of rows , guess more efficient on database side, fetch wanted rows network. is possible on sql side directly? you can use view all_tab_columns search columns in given table: declare v_table_name varchar2(30) := 'dual'; v_search_string varchar2(100) := 'x'; v

i'm having problem cmake cross compiler project. my cross compiler did not find used libraries. setup cross compiler tutorial cross compiler . now need libs installed on raspberrypi. have snychronised /lib , /usr direcotry pi computer in /opt/cross/rasp. toolchain file: # 1 important set(cmake_system_name linux) #this 1 not set(cmake_system_version 1) # specify cross compiler set(cmake_c_compiler /opt/cross/x-tools/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc) set(cmake_cxx_compiler /opt/cross/x-tools/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-g++) # target environment set(cmake_find_root_path /opt/cross/rasp) # search programs in build host directories set(cmake_find_root_path_mode_program never) # libraries , headers in target directories set(cmake_find_root_path_mode_library only) set(cmake_find_root_path_mode_include only) but when try compile program following linking error: /opt/cross/x-tools/arm-unknown-linux-gnueabi/lib/gcc/arm-

i have following code fibonacci both recursive , iterative versions: #include <stdio.h> typedef long long int; long long recursive (long long i) { if (i == 0) return 0; if (i == 1) return 1; return recursive (i-1) + recursive (i-2); } long long iterative (long long i) { int counter = i-1; int fib1 = 0; int fib2 = 0; // first iteration fib1 = 0; fib2 = 1; while (counter > 0) { int temp1 = fib1; int temp2 = fib2; fib1 = fib2; fib2 = temp1 + temp2; counter--; } } int main (int argc, char **argv) { printf("result: %lli\n", iterative(10)); return 0; } i tried compiling gcc -o2 optimization see if recursion perform better iteration, noticed interesting occurrence: when compiled -o2 , iterative function outputs 0 while if it's compiled without flag, outputs proper number. gcc -o2 fibonacci.c -o fib && ./fib : result: 0 gcc fibonacci.c -o fib &a

when comparing hard-coded strings user see not modify/change, culture info important. i assume not, want safe. example: static void main() { string hardstring = "iamhardcodei"; string hardstring2 = "iamhardcodei"; //compare hardstring , hardstring2, ignoring case, //and stuff based on result } the general recommendation string comparisons when "programmatic strings" (i.e. specified not usable or editable user directly the: stringcomparison.ordinal[ignorecase] . see post (of duplicate): which best use -- stringcomparison.ordinalignorecase or stringcomparison.invariantcultureignorecase?

i want reverse char string in c++. wrote code: #include <iostream> #include <string.h> using namespace std; int main(){ char word[80] = "polymorphism"; char rev[80]; int i, j; int l; l = strlen(word); for(i = 0, j = l; < l-1; i++, j--){ word[j] = rev[i]; } cout << rev << endl; return 0; } in terminal shows characters this: 83???uh??? ... your character array rev not 0 terminated. and istead of write rev writing word.:) word[j] = rev[i]; the loop wrong due condition i < l-1; there must be i < l; the program can following way #include <iostream> #include <cstring> int main() { char word[80] = "polymorphism"; char rev[80]; size_t n = std::strlen( word ); size_t = 0; ( ; < n; i++ ) rev[i] = word[n - - 1]; rev[i] = '\0'; std::cout << word << std::endl; std::cout << rev << s
