when press button, want change foreground color of selected item in list . so far, tried this: list.setforeground(display.getsystemcolor(swt.color_red)); but changes foreground color of items, not selected one. any ideas how solve this? doing list require custom drawing. better off using table instead (or tableviewer depending on requirements). here example of table want: public static void main(string[] args) { final display display = new display(); shell shell = new shell(display); shell.setlayout(new gridlayout(1, false)); shell.settext("stackoverflow"); final table table = new table(shell, swt.border | swt.multi); table.setlayoutdata(new griddata(swt.fill, swt.fill, true, true)); (int = 0; < 10; i++) { tableitem item = new tableitem(table, swt.none); item.settext("item " + i); } button button = new button(shell, swt.push); button.settext("color selected");

how can add property: <property name="myproperty" value="value"/> to batch job definition: <batch:job id="myjob"> <batch:description>description</batch:description> <batch:step id="step0"> <batch:tasklet ref="myjobcls"/> <batch:listeners> <batch:listener ref="myjobklistener"/> </batch:listeners> </batch:step> </batch:job> then can use property in run time. you can have properties in external file or inject in propertyplaceholderconfigurer xml: <bean id="propertyconfigurer" class="org.springframework.beans.factory.config.propertyplaceholderconfigurer"> <property name="location"><value>my_config.properties</value></property> <property name="properties"> <props> <prop key="myproperty">v

i have photo site noodling , have issue reactive sizing of browser window. images great @ 100%, when size down window landscape images start resize, understand sizing down meet width of browser window. however when small, mimic smartphone, want these images stack, makes more sense images portrait. idea go left right , top bottom when browser small. im kinda rusty @ css , cant remember how done. can please brutha out , point me in right direction can going? im doing thru wp override option, approach should follow css best, im tard more complex. the site here: http://jadanduffinphotography.com/ thanks! -jadan what suggest is: write css make images float: left; , position: relative; inside container div detect orientation of browser window according orientation, set width of container div this should make images display horizontally when possible , make them stack vertically when not. you should take @ this probably.

this code crashes program #include <cstdio> int main() { char *name1; char *name2 = "mark"; gets(name1); puts(name1); return 0; } whereas doesn't #include <cstdio> int main() { char *name1 = "mark"; char *name2; gets(name2); puts(name2); return 0; } why ? using mingw code::blocks ide. you lucky 1 crashes , other doesn't. both of programs produce undefined behavior. char *name2; gets(name2); you need point pointer valid , big enough memory able write it. writing uninitialized pointer. results in undefined behavior. undefined behavior not mandate crash, literally means behavior possible , in case might crash , may not nevertheless incorrect program. ideal solution use std::string . if insist on using char * need point pointer valid memory. e.g. char myarr[256]; char *name2 = &myarr;

sorry bad title... have base class like: template<class t> class gptr { public: typedef t basetype; gptr& operator=(const basetype& rhs) { ... } }; i want make subclassed specializations like: class graphicptr : public gptr<graphic> { ... }; however base-class assignment operator still returns gptr<graphic> not graphicptr , it's annoying have copy-paste code in case core assignment operator functionality should change later. is there neat way define base-class assignment operator returns type of actual class in use? in c++, base class has no idea of it's children. may add template parameter derived class , use it. template<class t, class derived> class gptr { public: typedef t basetype; derived& operator=(const basetype& rhs) { ... } };

i'm calculating difference between 2 dates using datetime() , it's working fine. problem want have days format able go above full month 30/31 or higher. $now = new datetime(); $future_date = new datetime($contest->expires_at); $interval = $future_date->diff($now); $enddate = $interval->format("%m month, %d days, %h hours, %i minutes"); the current problem when don't display months, days can go 30/31 , on carried on make new month resetting days count leftover days. want able display 42 days when difference 6 weeks kind of format: $enddate = $interval->format("%d days, %h hours, %i minutes"); is there quick fix or need manually convert timestamp seconds , use own function modulus operators this? you can try: $enddate = $interval->format("%a days, %h hours, %i minutes"); see dateinterval::format in manual. note take care of bug if you're working on windows.

we have 3 layered application wich every call service layer goes business layer , peresist data layer. components of each layer can call layer below; however because have hundreds of entities , have lots of services related crud operatins many contoverseries raised on our team. some believe sake of maintenance , ease of development it's better call data access crud services doing crud operation , bypassing business layer. on contrary saying have create wrapper data access of each entity in business layer , call these wrapper services , never allow services call data access layer. in idea way should take? ok crud services call data accesses , bypassing business layer? if there no business logic perform, there no reason enforce business layer. 3-tier architecture not arcane protocol, best practice formed assuming business processing. in current application accessing daos directly jsf controllers when there no business process involved. idea given java champion

i have question querying accounting data. for example, sample data show below table: table_test date amount 2013-01-01 12.00 2013-01-02 13.00 the output should this: date account debit credit 2013-01-01 abccompany 12.00 2013-01-01 vendorcompany 12.00 2013-01-02 abccompany 13.00 2013-01-02 vendorcompany 13.00 initially, think using union statement because may output sequece not important , sample sql show below select date 'date', 'abccompany' 'account', amount 'debit', '0' credit table_test union select date 'date', 'vendorcompany' 'account', '0' 'debit', amount credit table_test output: date account debit credit 2013-01-01 abccompany 12.00 2013-01-02 abccompany 13.00 2013-01-01 vendorcompany 12.00 2013-01-02 vendorcompany 13.00 but se

i getting proxy authorization required while uploading large files in play 1.2.5. after hitting upload button required action doesnt called.however when upload small sized files dont error.what can reason.please me out. this has nothing play. while can limit size of request (and therefore size of uploadable files) setting value play.netty.maxcontentlength in application.conf , by default there no limit . the problem caused proxy server sits between , play application requires authentication above request size. ask whoever responsible proxy server how circumvent problem (e.g. increasing max. request size or giving authentication credentials proxy).

in project create configuration file each clients(also can sqlite in each clients instead of configuration file). files include critical information policies. therefore end-user musn't add, delete, change configuration file or in file. i considering use active directory prevent users open folder include configuration file. is there standart way use secure configuration files? edit: of course speed of reading file important security edit2: can't db server because policies must accesible whithout internet connection too. server update file or sqlite tables in periods. , using c++. i'm sorry crush hopes , dreams, if security based on configuration file on client, you're screwed. the configuration file loaded , decrypted application , means values can changed using special tools when application runs. if security important, checks on server, not client.

i have class in c++ template class, , 1 method on class templated on placeholder template <class t> class whatever { public: template <class v> void foo(std::vector<v> values); } when transport class swig file, did %template(whatever_myt) whatever<myt>; unfortunately, when try invoke foo on instance of whatever_myt python, attribute error. thought had instantiate member function with %template(foo_double) whatever<myt>::foo<double>; which write in c++, not work (i syntax error) where problem? declare instances of member templates first, declare instances of class templates. example %module x %inline %{ #include<iostream> template<class t> class whatever { t m; public: whatever(t a) : m(a) {} template<class v> void foo(v a) { std::cout << m << " " << << std::endl; } }; %} // member templates %template(fooi) whatever::foo<int>; %template(

how can convert float bytes in little-endian format ? like 5.05 -> \x33\x33\x33\x33\x33\x33\x14\x40 like this: # let v = int64.bits_of_float 5.05 in = 0 7 printf.printf "%lx " (int64.logand 255l (int64.shift_right v (i*8))) ; done ;; 33 33 33 33 33 33 14 40 - : unit = ()

i'm doing maintenance work on application stores xml data in sql server. currently, application uses table store associated xsds. question: since xsd validation being performed in asp.net, there advantage storing xsds in xml schema collection instead? it's fair question... still put in xml schema collection. forces validation of data @ lowest possible level. if it's possible put bad data column, happen. takes developer working on app not careful are, or internal app hitting same table, or of bunch of other situations. it's storing int values in column of type varchar. can it... , maybe application validating data going in there indeed of type int. somehow or other, value "10n" eventually find way column. what? 1 of great things relational db enforces level of data validity, should use every tool @ disposal, including schema collections, imo.

i'm part of project rewrite se application in ee. we're using jboss 7.1.3 our supported application server, trying minimize specific code in interest of portability. a little background on our application...it accepts processing requests systems (mdb/webservice) , fulfills request interfacing number of other systems. system processing auditing database driven. current functionality in existing application application shuts down in event of database connection loss prevent unaudited processing. so, i've been looking around see if there standard way of recreating functionality in portable way. guess i'm wondering if there's standard way of stopping application programatically within application or if have thoughts on providing similar functionality. so far i've seen there may ways hook jboss via jmx , undeploy application or possibly stop mdb delivery...but i'm concerned portability since specific. i'm not concerned portability across ass ac

i have 2 magento eshops worked in past on major browsers except ie 7. after installed windows xp on computer , accessed eshops ie 8, had heartattack seeing aren't working should. before installing windows xp running windows 7 , websites looking on ie 8. now, same ie version, on different operating systems, gives me headaches! now, can explain me how 'debug' ie 8 parsing engine seeing errors , try modify templates? thanks.

i organise assembly code write reflects intended design. received understand namespaces principal way organise types achieve this. the issue have assembly, assembly , say, uses layer of implementation classes. of classes in layer1 part of implementation of layer1 , i'd reflect in way structure code. first thought try make classes in layer1 private, can see this not possible . logically, layer1 exposing classes a1 , b1 , c1 etc. , uses classes a2 , b2 , c2 etc. namespace assembly.layer1 { // "interface layer1" class a1 // ... class b1 // ... class c1 // ... // "implementation of layer1" class a2 // ... class b2 // ... class c2 // ... } // (one file per class) it seems 1 way address put a2 , b2 , c2 etc new namespace, assembly.layer1.layer2 . then, when i'm writing code in top-level namespace , using assembly.layer1 , intellisense shows me classes assembly.layer1 exposes. also, by convention , should refer 1

i'm going have grid of <div> s dynamically generated. each <div> same width. want evenly space them across container. , want them space 3 across, , start again on next line. however, final row may have 1 or 2 <div> s in it, need remain in same 'grid spacing' above rows. basically, want table type spacing, without using tables :) here's example html. below occur on 4 rows, final row having 1 item <div id='container> <div class='item'>content</div> <div class='item'>content</div> <div class='item'>content</div> <div class='item'>content</div> <div class='item'>content</div> <div class='item'>content</div> <div class='item'>content</div> <div class='item'>content</div> <div class='item'>content</div> <div clas

we have simple program (single-threaded) we bunch of random sample generation. using several calls of numpy random functions (like normal or random_sample ). result of 1 random call determines number of times random function called. now want set seed in beginning s.th. multiple runs of program should yield same result. i'm using instance of numpy class randomstate . while case in beginning, @ time results become different , why i'm wondering. when doing correctly, having no concurrency , thereby linear call of functions , no other random number generator involded, why not work? okay, david right. prngs in numpy work correctly. throughout every minimal example created, worked supposed to. my problem different one, solved it. never loop on dictionary within deterministic algorithm. seems python orders items arbitrarily when calling .item() function getting in iterator. so not disappointed this kind of error, because useful reminder of think when trying rep
