when updating schema, doctrine drops , add constraints. think, wrong... php app/console doctrine:schema:update --force updating database schema... database schema updated successfully!

[database] fail - database schema not in sync current mapping file. how can may fixed? after digging doctrine update schema methods, i've found issue. problem table names - "table.order" , "table.user". when doctrine makes diff, names become non equal, because of internal escaping (?). so, "user" != user, , foreign keys tables (order, user) recreating. solution #1 - rename tab

i´m programming simple thing in c# , wpf. have mainwindow button. if trigger button opens secon window: private void btnf4_click(object sender, routedeventargs e) { secondwindow second = new secondwindow(); second.show(); } naturally if trigger button 3 or 4 times, have 3 or 4 windows open. don´t want use showdialog(), want open second window once. mean if trigger button , window open, should nothing happen. thank you! make second instance variable parent window class , create new window if hasn't been created. of course need make sure null instance variable when second window closed. public class parentwindow ... { private secondwindow m_secondwindow = null; .... private void btnf4_click(object sender, routedeventargs e) { if (m_secondwindow == null) { m_secondwindow = new secondwindow(); m_secondwindow.closed += secondwindowclosed; m_secondwindow.show(); } }

i have noticed 'bug' or whatever internet explorer when viewing html emails. i'm using version 11 , still present. if want align table in center of page, causing text in <td> cells centered, if set attribute align="left" , use inline css specify text-align="left". here example code (try sending html email yahoo or gmail account , view in ie): <table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" style="background:#ccc;"> <tr> <td> <table width="650px" border="0" align="center" cellpadding="0" cellspacing="0" style="padding-left:11px;padding-right:11px;background:#fff;"> <tr> <td align="left" valign="top" style="text-align:left;">moreover, while in other animals can think of, eyes planted imperceptibly blend visual

i've filename myfile.txt , want simple script tells me when file has been modified. i'm using os.stat(file).st_mtime see if has been modified. if time has changed, file has been modified. how can use os.stat(file).st_mtime in while loop this? while file hasnt been modified: print "file not modified" print "the file has been modified" thanks in advance. something like mtime = os.stat(file).st_mtime while os.stat(file).st_mtime == mtime: print "file not modified" print "the file has been modified"

i have 2 lists zip , go through zipped result , call function. function returns list of strings response. want collect responses , not want have sort of buffer collect responses each iteration. seq1.zip(seq2).foreach((x: (obj1, obj1)) => { callmethod(x._1, x._2) // method returns seq of string when called } what want avoid create listbuffer , keep collecting it. clues functionally? why not use map() transform each input corresponding output ? here's map() operating in simple scenario: scala> val l = list(1,2,3,4,5) scala> l.map( x => x*2 ) res60: list[int] = list(2, 4, 6, 8, 10) so in case like: seq1.zip(seq2).map((x: (obj1, obj1)) => callmethod(x._1, x._2)) given function returns seq of strings, could use flatmap() flatten results 1 sequence.

i make complete text document several sources (since 1 of file source change, want doc change). i have pass through translator develop. pass language argument, make cleaner. yesterday, late @ night, dreamed of makefile this... #makefile # ... my_complete_doc.%.html: my_trans_exe header.%.html $(wildcard source/*.%.html) $< --language $(variable_for_%) > $@ (?) replace % languages have own header.language.html files. , file my_completed_doc.language.html changed 1 of source/*.language.html changed? (?) how % replaced in several prerequisites, possibly wildcard , in recipe? first, easy problem: wish use '%' variable in recipe. answer use '$*' automatic variable: my_complete_doc.%.html: my_trans_exe ... $< --language $* > $@ then easy question: yes, header.%.html prerequisite correct. when try build my_complete_doc.dutch.html make evaluate header.dutch.html , when try build my_complete_doc.french.html , make eval

so don't know how describe question best way since never worked in jsp before, , jumped in project , needs finish it. sorry if unclear, ask me , i'll try reply fast. so got language check html tags, looks this: <p data-bind="if: 'en_us' == currentlang()">english text</p> which works fine, want put in if/else statement. in php, write like: <?php if((currentlang() == 'en_us)) { echo 'english text'; else { echo 'italian text'; } ?> so how do this, checking currentlang() in .jsp file? i try use f:subview tag ( http://docs.oracle.com/cd/e17802_01/j2ee/javaee/javaserverfaces/2.0/docs/pdldocs/facelets/f/subview.html ) , put condition in rendered attribute <f:subview rendered="if: 'en_us' == currentlang()">english text </f:subview> i think should work.

i have number of wx.panels, each containing matplotlib figure (a thumbnail gallery). want user able drag , drop of these figures another, bigger panel. what tried binding wx.evt_motion of each thumbnail panel. unfortunately, seems event consumed figure never fires. i tried connecting 'motion_notify_event' of each figure 1 fires when mouse on particular figure. is possible somehow disable matplotlib events, event gets panel underneath? or there solution? you need take @ documentation , demos wx.droptarget , wx.dropsource , overview . code examples see: samples/dnd subdirectory of wxwidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxwidgets/trunk/samples/dnd you consider adding tick box or button each thumbnail makes 1 large view.

one easy question reason cannot see answer to: i working on matlab project need interpolate specific set of data. have 2d-matrix mat , 2 vectors x , y assign value each column , row (strictly monotonically increasing of course). matrix 0s, except diagonal lines amongst has nonzero values. i wish interpolate data along thise lines on entire area, linear interpolation should enough now. approach is [y,x] = meshgrid(y,x); %create meshgrid out of grid vectors ysave=y;xsave=x; m = mat; %now, eliminate elements mat 0 since want interpolate there y(mat==0)=[]; x(mat==0)=[]; m(mat==0)=[]; interpolant = scatteredinterpolant(y',x',m'); % , create our interpolant result = interpolant(ysave,xsave); however, when execute code, interpolated picture not not resemble "intuitive" interpolation @ - not have original data points included... doing wrong? thanks help! edit comments, visibility: imgur.com/a/7baxm visual respresentation of data. top picture interpolated

when working talend, find when trying create outputs tmap components, type can create *new output* (main) . yet, need create lookup outputs. (to pipe other tmaps have main input). does know cause of issue and/or way fix it? the distinction main/lookup has sense incoming connections. outgoing connection scope, there's no difference between lookup or main: it's vectorized stream of data. pratically speaking, means can connect main connection of wanna-be-lookup tmap real-main tmap: since cannot have more 1 main connection, additional one(s) automatically marked lookup connection(s). you can change flow type incoming connections (from main lookup , vice-versa) @ time doing right-click on connection, "change connection order" it's quite easy mess-up mind while doing this. remember main connection 1 starts component has green background.

when create view, create in context of default database. none of references table have prefix explicitly specify database. however, when edit view in workbench automatically adds database prefix! i don't want database prefix because when restore database under different name causes restore fail. is possible stop prefixing in view edit or there way round restore issue? regards, bobbyy that's not possible. views stored in specific databases, not in space "above" databases. consider following... use playground_a; /*or whatever database*/ create view view_whatever select * table_whatever; use playground_b; select * view_whatever; /*here error view_whatever not exist*/ select * playground_a.view_whatever; /*this works*/ that's why there database prefixes in view definition. the possibility see, use stored procedure database name parameter. in procedure you'd use prepared statement execute concated string of query , database name param

here table trying query using cursor: create table raceresult (raceid number(5), horseid number(5), jockeyid number(5) not null, position varchar2 (3)); i have written function query , return horse id's have come first in race. create or replace function get_horse (horsepos in varchar2) return varchar2 pos varchar2; cursor c_horse select horseid raceresult position=horsepos; begin open c_horse; fetch c_horse pos;- if pos%notfound pos := 9999; else if c_horse = ('1st') return pos; end if; close c_horse; end get_horse; it not work, , beyond puzzled on try next.

i have created website , within website there list, user can insert items, info user inputs saved database, inside table have 'id', 'content'(which to-do item) , 'status' have put status in here want user able click done, partially done or not done, values 1,2 , 3. // update list view (var i=0; i< res.length; i++){ $("<li/>", {"id": res[i].id, "text": res[i].content + res[i].status}).appendto(todo.list); // extend width if msg long if(res[i].content.length >= 35){ $('#'+res[i].id).css("height","50px"); the to-do list in javascript, if statement if status 1 turn green, , similar other two, different colours, having trouble getting code correct. thanks. all need add class li item, in css target class different colour: $("<li/>", {"id": res[i].id, "text": res[i].content + res[i].status, "class": 'status-'

i want know open source projects used things arena, allocators, overloading new , etc. refers c + + language. see google perf tools , jemalloc . last 1 used in freebsd default malloc implementation. so, every project use of 2 use arenas, cause both use them internally. new operator in c++ implemented libc's malloc function. also, see nginx http server sources , allocates memory pool session before connection created (but it's written in pure c). apache has apr pools library .

i have customized uitableview, cells have different background color (set in custom backgroundview). however, background color applied within cell, not extended inset area of separator. can see in screenshot, there white area left of colored separator. how can change color of white line? make line "disappear" setting same color cell background. thanks! setting cell's background colour same contentview's background colour seems give best results. cell.backgroundcolor = cell.contentview.backgroundcolor; that handle cases accessoryview wrong colour well.

this code creating geofence: geofence *geofence = [[geofence alloc] init]; [geofence setradius:100.0]; [geofence setidentifier: @"fence1"]; [geofence setlocation:currentlocation]; clregion *region1 = [[clcircularregion alloc] initwithcenter:[geofence.location coordinate] radius:geofence.radius identifier:geofence.identifier]; region1.notifyonentry=yes; region1.notifyonexit=yes; [self.locationmanager startmonitoringforregion:region1]; i that, above code works, meaning geofence have been created. there's problem i've been encountering. i have .gpx files (in using simulation of current location), distances center of region/geofence follows: 55m, 90m, 150m, 200m, 300m, 500m, 1km, 5km , 10km. my problem is, seems geofence radius not 100m, because when simulate using gpx files distance center of geofence 55m, 90m, 150, 200m, 300m, 500m, 1km. delegate methods of loca

i hoping out there may able me out problem having motion capture system. looking stream real-time xyz marker positions matlab online processing; however, have real-time access 2d marker positions seen each camera (8 cameras in total). markers located on human subject moving relatively within capture volume. i have been racking brains, , exhausting google, stackoverflow, , multiple view geometry text answer question: can reproject 2d marker positions 3d space if know precisely projection matrices of each camera? or, still bound triangulate corresponding 2d points between camera views obtain xyz position of marker? i really really hope can obtain 3d marker coordinates knowing 2d positions seen given camera, , projection (intrinsic+extrinsic) matrix - doubtful... i appreciate in advance! cheers! yes! can obtain 3d position of marker number of 2d positions. track-it-yourself open-source library hosted @ google code. allow compute 3d position 2 2d markers.
