i querying database latest row entered , id column only, sure 1 value. however, unable print variable unless in foreach loop, not accessing 0th element giving me output. i use line of code querying latest row's id added: $id = $db->query("select max(id) fm;"); when use foreach loop, following output: loop: foreach ($id $i) print_r($i); output: array ( [max(id)] => 20 [0] => 20 ) however, when use print $id[0]; or print $id["max(id)"]; http error 500. how can single value id , put in variable, id is? thanks instead of selecting max(id) have use lastinsertid() method $id = $db->lastinsertid(); right after calling insert query

i studying prolog using ivan bratko book: programming artificial intelligence , finding difficulties implement final part of exercise proposed the exercise program use graphs decide how move blocks , arrange them in order. this image related program have do: as can see in previous immage blocks a,b,c can moved using number of admissible moves are: a block can moved if @ top of stack a block can moved on ground (on void stack) a block can moved on block (at top of stack contains others blocks) so these admissible moves induce graph of possible transitions between 1 state , state in graph, this: so, can se in previous graph can rappresent situation using list of 3 sublist. each sublist rappresent stack can put blocks according previous constraints so example situation of central node of previous graph can represented by: [[a], [b], [c]] because each stack contains single block. the situation represented node @ top left stacked 1 below other blocks c,a,b ...

i'm trying write relatively deep class heirarchy , compiler keeps throwing "no matching function call [default constructor bass class]". here's scenario: class { a(int);//note, no default constructor } class b : public { b(int i, int j) : a(i), somemembervariable(j) {} int somemembervariable; } class c : public b { c(int k, int l) : b(k, l) {} } and compiler throws error on line constructor of class c saying "no matching function call a::a()" , tells me use a::a(int). i understand don't have default constructor class a, , compiler getting confused when try subclass subclass. however, don't understand why. have used initialization list avoid that. if use classes 2-levels deep works fine, third class gives me error. doing wrong here? as people commented needed make constructors public , code had formatting issues: class { public: a(int a) : blah(a) {}; //note, no default constructor int blah; }; c...

i'm trying match specific datetime format in php's regex: dd-mm-yyyy hh:ii:ss it should in format. meaning example when first day of month there must leading zero. e.g.: 01-01-2013 01:01:01 i tried following pattern: ^[0-12]{2}-[0-31]{2}-[0-9]{4} [0-23]{2}:[0-59]{2}:[0-59]{2}$ but above pattern fails on timestamps like: 09-05-2013 19:45:10 . http://rubular.com/r/egbahwincr i understand may not correct approach validate date time this, want know wrong above. the problem when checking "ranges", example [0-12] @ beginning. character class, , telling regex match 0 through 1, , 2. if added more numbers in after 1st one, isn't working expecting. changing regex (focused on [0-12] initial), [0-319]{2}-[0-12]{2}-[0-9]{4} [0-23]{2}:[0-59]{2}:[0-59]{2}$ , match 09-01-2011 11:11:10 . ensuring there valid numbers each of spaces requires little thinking outside box. regex: (0[1-9]|[12][\d]|3[0-2])-(0[1-9]|1[0-2])-[\d]{4} (0[1-9]|1[\d]|2[0-...

a quick introduction source of problem: i have datagridview that's child of resizable panel , can adjusted user's mouse input. when panel resized, datagridview 's size mirrored along it. idea that, instead of columns , rows of grid auto-sizing fit contents of cells or gridspace, number of columns , rows determined size of grid. width , height of rows , columns pre-determined , don't need adjusted. point of let user adjust row , column quantity. best demonstrated short clip of code in action: resizing panel to accomplish this, check if panel resizing, and, depending if it's shrinking or growing, columns adjusted accordingly. there's magic going on here, looks this: if(panel_width_is_growing) { if(margin >= growing_threshold) { datagridviewcolumn column = new datagridviewcolumn(); column.name = "run " + (datagridview.columns.count + 1).tostring(); column.headertext = "run " + (datagridview.columns...

i want able iterate on matrix apply function each row. how can numpy matrix ? use numpy.apply_along_axis() . assuming matrix 2d, can use like: import numpy np mymatrix = np.matrix([[11,12,13], [21,22,23], [31,32,33]]) def myfunction( x ): return sum(x) print np.apply_along_axis( myfunction, axis=1, arr=mymatrix ) #[36 66 96]

i have wpf menu add items programatically. consist of couple of menuitems. however, in 1 of menuitems add listbox.(i needed scroller because have many items , made easy). the menu looks fine , works. problem after select (click on) on listbox menu closes expected; if move mouse on it, menu pops open. i have searched on internet no luck not surprising since pretty custom stuff. the last thing tried checking events , see if can handle them. can detect mouseover . not see popopen or onclick event menu. any ideas if can detect these events? other ideas, suggestions appreciated. , if there way add scroller bunch of menuitems may change design well.

i have following code dictionary. void dictionary::translate(char out_s[], const char s[]) { (int i=0;i<numentries;i++) { if (strcmp(englishword[i], s)==0) break; } if (i<numentries) strcpy(out_s, elvishword[i]); which gives me error name lookup of changed iso , mentions code accepted if use -fpermissive . if try , initialize variable outside loop generates whole load of errors. any ideas? thanks in advance. not "for iso" (perhaps read entire error message... ), iso c++. problem scope of i variable for loop (since definition inside initialization of loop). since seems want use outside loop, declare so: int i; (i = 0; < foo; i++) { // ... } do_safe_stuff_with(i); // valid

please suggest me use best database when developing desktop application using java. i planning develop student information system want store , retrieve student information. using java swing develop system. can suggest me best db use application. "best" incredibly subjective, let's narrow down other criterion lightweight , integrated. in category choose h2 , hsqldb or apache derby . these systems written in java can integrate them straight application without need install, set , maintain server, make distribution , setup easier, , have decent feature set , performance. ease of use end users that's simple get. the h2 webpage contains small comparison stable can select "best" fit requirements.

i have spring security configured authenticate against ldap server. <security:authentication-manager > <security:ldap-authentication-provider user-dn-pattern="uid={0}" /> </security:authentication-manager> after authentication want load roles local database same user. how can load local database roles using "ldap-authentication-provider"? if add second authentication provider below: <security:authentication-manager > <security:ldap-authentication-provider user-dn-pattern="uid={0}" /> <security:authentication-provider ref="daoauthenticationprovider" /> </security:authentication-manager> daoauthenticationprovider added, spring not use second provider when first auth provider authenticates user. if first auth provider fails authenticate goes next in list. so have customize <security:ldap-authentication-provider user-dn-pattern="uid={0}" /> to load rol...

i quite new hibernate , programming databases in general honest... i've tried save graph-like structure database. suppose have java class this: public class user { @onetomany(cascade=cascadetype.all) private collection<user> followers = new arraylist<>(); @onetomany(cascade=cascadetype.all) private collection<user> friends = new arraylist<>(); @id private string name; ..... } the problem want save postgesql database using hibernate. found quite nontrivial. 1 problem example is: suppose do: user user1 = new user("user1"); user user2 = new user("user2"); user1.getfollowers().add(user2); user1.getfriends().add(user2); now if merge on user1 object there issue key uniqueness constraint. wonder if issue because misconfigured hibernate annotations save structure or entirely wrong approach represent graph in such way using hibernate ? appreciated. personally go generated id column, , not use user...
