i try use instances of bitmapimage class in circle receive error messages bitmapimage not initialized. how check bitmapimage initialized before use it? there 2 events commonly used when working bitmaps, 1 fires of when image opened , when image failed; var myimage = new bitmapimage(new uri(@"images/img.jpeg",urikind.relative)); myimage.imageopened += myimage_imageopened; myimage.imagefailed += myimage_imagefailed; void myimage_imagefailed(object sender, exceptionroutedeventargs e) { //handle failed event } void myimage_imageopened(object sender, routedeventargs e) { //handle image opend ok event }

why when use this: (assuming i = 1 ) divid = "question-" + i+1; i question-11 , not question-2 ? use instead: var divid = "question-" + (i+1) it's common problem , doesn't happen in javascript. idea + can represent both concatenation , addition. since + operator handled left-to-right decisions in code this: "question-" + i : since "question-" string, we'll concatenation, resulting in "question-1" "question-1" + 1 : since "queston-1" string, we'll concatenation, resulting in "question-11" . with "queston-" + (i+1) it's different: since (i+1) in parenthesis, value must calculated before first + can applied: i numeric, 1 numeric, we'll addition, resulting in 2 "question-" + 2 : since "question-" string, we'll concatenation, resulting in "question-2" .

i have table column contains 'valid until' date , want make sure can set null in single row within table. there easy way this? my table looks (postgres): create table 123.mytable( some_id integer not null, valid_from timestamp without time zone not null default now(), valid_until timestamp without time zone, somestring character varying) some_id , valid_from pk. want nobody enter line null value in column valid_until if there line null pk. thank you in postgresql, have 2 basic approaches. use 'infinity' instead of null. unique constraint works expected. or if cannot that: create unique index null_valid_from on mytable(someid) valid_until null i have used both approaches. find first approach cleaner , allows use range types , exclude constraints in newer versions of postgresql better (to ensure no 2 time ranges overlap based on given given someid), bt second approach useful first cannot done.

edit: question came , think aced it! go stackoverflow!! :d i have exams coming up, , 1 of questions on last year's exams spot problem implementation of following constructor , write corrected one. rectangle::rectangle(string col, int len, int br) { setcolour(col); length =len; breadth=br; } the class definitions follows: class polygon { public: polygon(string col="red"); void printdetails(); // prints colour virtual double getarea()=0; void setcolour(string col); private: string colour; }; class rectangle : public polygon { public: rectangle(string, int, int); void printdetails(); // prints colour , area // part 3, delete line below double getarea(); private: int length; int breadth; }; i've written code compiler , runs fine. i'm guessing question relating inheritance, since string colour; private, setcolour public cant figure out. unless rectangle::rectangle(string col, int len, int br):le

we have rails application test rspec. want spec operations rely on memcached. best practice so? i thought of doing stubbing calls rails.cache . idea? as per @pan thomakos suggestion, i'm adding additional details 1 of scenarios i'm trying test: we have concept of accounts in our system, therefore on every request retrieve current user , current account. because there not many accounts in system, keep them in cache , retrieve them there. def self.find_by_slug(slug) rails.cache.fetch(account.cache_key_for_slug(slug), :expires_in => 1.day) { super } end for reason, caching in case isn't nice have behavior, expected behavior , thing want test. therefore turning off caching won't do. test without stubbing imho! the sequence this: cache.flush # or equivalent cache.get(slug).shouldbe null # test cache empty method.find_by_slug(slug).should == 'some value' # test method words cache.get(slug).should == 'some value' # test

i have app requires connection remote windows. have done use mapped drive build connection on windows startup menu. partial codes this: @if not exist \\remotepc\sharedfolder net use * \\remotepc\sharedfolder /user:user1 pwd /persistent:yes the net use map works fine. mapped drive 1 available network drive letters. in app, unc name used instead(\remotepc\sharedfolder). the issue(not sure issue) after several reboots, can see list of disconnected drivers file explorer: i not sure letters used if reboot pc many times? clean disconnected network drives. can batch script? tried use net use again disconnected drive, deletes ok first time, stays in file explorer. net use t: /delete notes: not sure usage of option /persistent:yes. think should reconnect network drive after log in or reboot. not happen. that's why added scripts start menu. realize other file explorer tools display disconnected network drives. each time reboot, 1 more disconnected network drive appears.

how return more 1 node on page? here code using, returns 1st node found. $dom = new domdocument; $dom->loadhtmlfile($url); $xpath = new domxpath($dom); $users= $xpath->query('//b[@class="xc_user"]'); echo $users->item(0)->nodevalue; $users domnodelist, can iterate over: foreach($users $node) { echo $node->nodevalue; }

to replace multiple words, i'm using looping thru candidates, , replacing 1 one. there better way? create or replace function "myreplace"(text, _varchar, _varchar) returns "pg_catalog"."text" $body$ declare int; result text; begin result = $1; in 1 .. array_length( $2, 1 ) loop result = replace( result, $2[ ], $3[ ] ); end loop; return result; end $body$ language 'plpgsql'; besides making stable , strict, , switching using pl/perl or c, there isn't optimization can make faster.

i have requirement have pass values next page via querystring. querystring coming third party , need have on otherpage analysis. i response.redirect , add querystring recieve them other page. problem .net environment encoding/encrypting of special characters used them dont want not bring correct values in new page. example: passed url : abcd.efgh=testing|value1=rtedf%20value2%202010-04-07%207pm|value3=aaaa this gets changed abcd.efgh=testing|value1%3drtedf+value2+2010-04-07+7pm|value3%3daaaa it looks "=" becomes "%3d" , "%20" space becomes "+" how can stop encoding of url , pass in original form. your querystrings being url encoded . standard behaviour due how urls should formatted. need on receiving page use urldecode in order original string.

i've got windows svc running asynchronously (i've edited methods , parameters make them async), little like: http://msdn.microsoft.com/en-us/library/ms731177.aspx however, call task want run asynchronously (the call service/server), , update ui (using reportprogress() on backgroundworker - of happening in dowork() method of backgroundworker). however, call endxxx method results, problem is, shouldn't code like? while (!asyncresult.iscompleted) { // ui updating etc here... } // call endxxx here. however, approach locks ui. @ moment, code (and doesn't lock ui): iasyncresult res = null; try { res = servicex.beginxxx(resultcallback, ""); } catch (faultexception<managementexception> managementex) { logger.error(managementex.detail.tostring()); messagebox.show("could not add printer. see log.");

with mutable types, difference in behaviour between value , reference types clear: // mutable value type pointmutstruct pms1 = new pointmutstruct(1, 2); pointmutstruct pms2 = pms1; // pms1 == (1, 2); pms2 == (1, 2); pms2.x = 3; mutatestate(pms1); // changes x property 4. // pms1 == (1, 2); pms2 == (3, 2); // mutable reference type pointmutclass pmc1 = new pointmutclass(1, 2); pointmutclass pmc2 = pmc1; // pmc1 == (1, 2); pmc2 == (1, 2); pmc2.x = 3; mutatestate(pmc1); // changes x property 4. // pmc1 == (4, 2); pmc2 == (4, 2); with immutable types however, difference less clear cut: // immutable value type pointimmstruct pis1 = new pointimmstruct(1, 2); pointimmstruct pis2 = pis1; // pis1 == (1, 2); pis2 == (1, 2); pis2 = new pointimmstruct(3, pis2.y); // can't mutate pis1 // pis1 == (1, 2); pis2 == (3, 2); // immutable reference type pointimmclass pic1 = new pointimmclass(1, 2); pointimmclass pic2 = pic1; // pic1 == (1, 2); pic2 == (1, 2); pic2 = new pointimmclass(3, pi
