i new unit test , wondering how start testing. application working on, not have unit test. winform application , interested test data layer of application. here example. public interface icalculatesomething { someoutout1 calculatesomething1(someinput1 input1); someoutout2 calculateosomething2(someinput2 input2); } public class calculatesomething : icalculatesomething { someoutout1 icalculatesomething.calculatesomething1(someinput1 input1) { someoutout1.prop1 = calculatefrominput1(input1.prop1, input1.prop2); someoutout1.prop3 = calculatefrominput2(input1.prop3, input1.prop4); return someoutout1; } someoutout2 icalculatesomething.calculateosomething2(someinput2 input2) { someoutout2.prop1 = calculatefrominput1(input2.prop1, input2.prop2); someoutout2.prop3 = calculatefrominput2(input2.prop3, input2.prop4); return someoutout2; } } i test these 2 methods in calculatesomething. methods impleme

is there way place multiple links in linklabel control in windows forms? if set this this.linklabel.text = ""; foreach (string url in urls) { this.linklabel.text += url + environment.newline; } it merges 1 link. thanks in advance. yes, though there isn't way can tell directly designer, easy manage via code: var linklabel = new linklabel(); linklabel.text = "(link 1) , (link 2)"; linklabel.links.add(1, 6, "link data 1"); linklabel.links.add(14, 6, "link data 2"); linklabel.linkclicked += (s, e) => console.writeline(e.link.linkdata); basically, links collection on label can host bunch of links in linklabel . linkclicked event contains reference specific link clicked can access link data associated link, among other things. the designer exposes linkarea property defaults include of text of linklabel . first link add links collection automatically change linkarea property reflect first link in collection.

this original question, not answered , thought id post again of strategies have tried, , little more specific. i want create dynamic admin site, based on if field blank or not show field. have model has set number of fields, each individual entry not contain of fields in model , want exclude based on if field blank. project bridges, , put in practical terms have model has every bridge part in (this equivalent 100), each individual bridge (mapped each unique brkey) not have 100 bridge parts. , so, can prepopulate of fields have, admin site has 100 other fields, , not display fields not used on admin site specific bridge, fields differ pretty every bridge. like said before, have unique bridge identifier(a unique 15 digit string), correlates each bridge, , of various different variables describe bridge. i have set user go url unique bridgekey , create entry of bridge. (as testing on local machine) localhost/home/ brkey , code in views.py corresponds url is final route ha

regardless of whether public, private or protected inheritance, private members of base class not accessible functions exclusive derived class. this conclusion. correct? related notes appreciated. also, in private inheritance, public members of base class private in derived class new functions of derived class can still access them directly. correct? why not test it? class base { private: int a; }; // private inheritance. class : private base { public: a() { = 0; } }; this gives me: error: 'int base::a' private the type of inheritance not matter when comes ability class access it's base-classes private variables.

we've been facing problem time , have no idea what's going on. hope i'm missing obvious. here's situation: we've got bunch of windows computers out there , each 1 of them running apache tomcat. webapps folder of these tomcats contains, among other things, war file java web app ( myapp.war ), directory tree corresponds deployment of web app, , simple folder (not web app deployment) contains .properties file. webapps |--myfolder | `--myfile.properties |--myapp | |--meta-inf | |--web-inf | |--img | ... |--myapp.war ... the myapp application reads file myfile.properties time time. not read often. when should quick operation: open file, read couple properties, close. code clean , simple, file stream should closed in face of exceptions. the myapp application hot redeployed overwriting myapp.war file. finally, computers aren't in friendly environment: suffer power outages or they're not shut down properly. the problem we

how sonarqube rule squid:s1200: classes should not coupled many other classes (single responsibility principle) count coupling number towards limit of 20? it seems counts classes standard java packages java.lang.* , java.text.* , java.util.* in rule's limit of 20. if use java integer class, i've used 1/20 of rule's limit. additional info: sonarqube version: 4.5.1 the best way answer question directly @ source code of rule : https://github.com/sonarsource/sonar-java/blob/c1f15b81bcd9d643ab403aeea6e1606040f84eac/java-checks/src/main/java/org/sonar/java/checks/classcouplingcheck.java so counts every declared type. , indeed if use java.lang.integer count 1 type 1/20 of rule's limit. the news can configure '20' magical number in quality profile.

everything looks fine in ib. when run app using iphone5/iphone6/ipad sims, it's mangled. in ib: in iphone6 sim: in above sim, buttons cut. textfield , textview cut. tf & tv, aligned center trail off edges on both sides. i have buttons width set editor > pin > widths equally the title label set horizontal center in container constraint the textfield , textview have horizontal center in container and editor > pin > width is there way fix this? -- edit -- after few tries constraints, looks have working except 2 buttons. current listing of constraints: as suggested others, should consider using auto-layout feature if plan on constructing views using ib. here tutorial links: raywenderlich.com part one youtube video 1 covers bit of size clases hope help. updated: i've read updated post, need add width , height constraints. view see in ib right 600 600 points, , simulator 1 smaller,
