how can use crtp in c++ avoid overhead of virtual member functions? there 2 ways. the first 1 specifying interface statically structure of types: template <class derived> struct base { void foo() { static_cast<derived *>(this)->foo(); }; }; struct my_type : base<my_type> { void foo(); // required compile. }; struct your_type : base<your_type> { void foo(); // required compile. }; the second 1 avoiding use of reference-to-base or pointer-to-base idiom , wiring @ compile-time. using above definition, can have template functions these: template <class t> // t deduced @ compile-time void bar(base<t> & obj) { obj.foo(); // static dispatch } struct not_derived_from_base { }; // notice, not derived base // ... my_type my_instance; your_type your_instance; not_derived_from_base invalid_instance; bar(my_instance); // call my_instance.foo() bar(your_instance); // call your_instance.foo() bar(invalid_instance); // c...

i having problem displaying javascript string embedded unicode character escape sequences (\uxxxx) initial "\" character escaped "&#92;" need transform string evaluates escape sequences , produces output correct unicode character? for example, dealing input such as: "this &#92;u201ctest&#92;u201d"; attempting decode "&#92;" using regex expression, e.g.: var out = text.replace('/&#92;/g','\'); results in output text: "this \u201ctest\u201d"; that is, unicode escape sequences displayed actual escape sequences, not double quote characters like. as turns out, it's unescape() want, '%uxxxx' rather '\uxxxx': unescape(yourteststringhere.replace(/&#92;/g,'%'))

is there way determine if loop iterating last time. code looks this: int[] array = {1, 2, 3...}; stringbuilder builder = new stringbuilder(); for(int : array) { builder.append("" + i); if(!lastiteration) builder.append(","); } now thing don't want append comma in last iteration. there way determine if last iteration or stuck loop or using external counter keep track. another alternative append comma before append i, not on first iteration. (please don't use "" + i , way - don't want concatenation here, , stringbuilder has append(int) overload.) int[] array = {1, 2, 3...}; stringbuilder builder = new stringbuilder(); (int : array) { if (builder.length() != 0) { builder.append(","); } builder.append(i); } the nice thing work iterable - can't index things. (the "add comma , remove @ end" nice suggestion when you're using stringbuilder - doesn't work things...

i have huge query uses case/when often. have sql here, not work. (select case when xyz.something = 1 'sometext' else (select case when xyz.somethingelse = 1) 'someothertext' end) (select case when xyz.somethingelseagain = 2) 'someothertextgoeshere' end) end) [columnname], whats causing trouble xyz.somethingelseagain = 2 , says not bind expression. xyz alias table joined further down in query. whats wrong here? removing 1 of 2 case/whens corrects that, need both of them, more cases. select case when xyz.something = 1 'sometext' when xyz.somethingelse = 1 'someothertext' when xyz.somethingelseagain = 2 'someothertextgoeshere' else 'something unknown' end columnname;

i need send html email. email clients (outlook, thunderbird ..) entourage can receive , read email without major problems. entourage, though breaking content , displays few lines beginning. my guess has way how entourage handles quoted-printable encoding. important headers of email set: content-type: text/html; charset=iso-8859-1 content-transfer-encoding: quoted-printable the same behaviour in entourage occurs when email sent multipart/alternative alternative plain text. content of email displayd until character =00 occurs (encoded nul?). is entourage bug behaviour? or doing wrong? the problem indeed *=00* characters. before sending email, need prepare quoted-printable encoding , remove null characters. $str = preg_replace('/\x00+/', '', $str);

i think each row in sql server given unique number. how can include in sql query results? if referring row number provided management studio when run query, there no way because not exist. management studio generates on fly. can however, recreate sequential number using row_number ranking function if using sql server 2005 or later. note should never assume database return rows in specified order unless include order statement. query might like: select .... , row_number() on ( order t.somecolumn ) num table t order t.somecolumn the order in on clause used determine order creating sequential numbers. order clause @ end of query used determine order of rows in output (i.e. order sequence number , order of rows can different).
