i'm doing test on very, simple application using spring . my app have have one bean , i'm injecting simple string class , printing value. so far working . what need: i want string configuration file, create file inside /src/main/resource what did: 1) on application-context.xml add: <context:property-placeholder location="classpath:myconfigfile.properties" /> 2) on application-context.xml change simple string use ${name_test}: <bean id="hello" class="com.dummy.sayhello"> <property name="name" value="${name_test}" /> </bean> 3) double check myconfigfile.properties , contains "name_test=jacktheripper" 4) output not 'translating' value config file, have output when run app: hello ${name_test} and i'm stuck here, clue, tips??? just fyi i use this tutorial tests, maybe help. i add log4j maven dependencies , log4j config file , works fin

a question builds upon to "new" or not "new" foo object1 = new foo(); // operations later ... object1 = new foo(); is i'm attempting advisable? , if foo implements idispoable, need call dispose before calling new operator second time? yes, you're doing in example fine. the object1 variable reference object of type foo . after first new assignment refers 1 particular instance of foo ; after second new assignment refers different instance (and original instance becomes eligible garbage collection, assuming there's nothing else referencing it). and yes, if foo implements idisposable should dispose it, preferably using using block, although personal preference use separate using variables each block: using (foo first = new foo()) { // } using (foo second = new foo()) { // else }

in current project, working on word processing & highlighting solution. typically every call class processing approximately 4000-5000 words long strings. the structure looks this public string parsetext(string inn) { //heavy parsing } public string highlighttext(string inn) { var cleaned = cleanuptext(inn); var parsed = parsetext(cleaned ); //highlight algorithm var formatted= parsetext(parsed); return formatted; } public string cleanuptext(string inn) { //heavy parsing } public string formattext(string inn) { //heavy parsing } so feel passing around same string around different methods decreases performance. though string reference type, creates new string , allocates new memory each passed variable due immutability nature of it. different other user generated

i working on java project after period using c++ , c#, , have doubt best practices field initialization in constructors. basically, suppose have simple point class. in c++ field initialization in constructor like: class point { public: // default constructor point(double x, double y) : x(x), y(y) { } protected: // coordinates double x, y; }; in c# ... class point { // coordinates, automatic properties public double x { get; protected set; } public double y { get; protected set; } // default constructor point(double x, double y) { x = x; y = y; } } in java ... best practices suggest define getters / setters fields must accessed outside. advisable use them inside class well? doubt comes fact eclipse seems comfortable converting each this.field = field in class code setfield(field) fields have getters / setters, if reading / writing happens inside class code (therefore wouldn't need use class interface). this

previously, asked this question compound indexes on polymorphic foreign keys in activerecord . basis of question understanding indexes should based on cardinality of column, , there's pretty low cardinality on rails's sti type , polymorphic _type columns. accepting answer question right -- that's there's value indexing both high cardinality _id columns , low cardinality _type columns, because have high cardinality -- next question is: how should order compound indexes? an index of [owner_id, owner_type] places field higher cardinality first, while [owner_type, owner_id] places field higher cardinality second. query using former key more performant query using latter key, or equally performant? i ask because has particular bearing on how order compound keys tables serving sti models. sti rails finders query on type column -- again column of low cardinality. type column therefore queried more other indexes. if type column queried more often, maybe makes

(arbitrary means $x$ grid along points $x_1,...x_n$ , same goes $y$ grid.) draw arbitrary object on top of (say rotated rectangle, or circle), , efficiently calculate fraction of each cell overlapped object: if cell entirely inside bounds of object, 1.0; if cell entirely outside, 0.0; if half of cell covered object, 0.5. if displayed image , scaled 1 black , 0 white, result antialiased drawing of black object. my application question in python, , seems capability might provided existing graphics library. there python module test fractional intersection of rectangle , arbitrary object? there python library can @ least efficiently test if point inside arbitrary object rotated rectangle? you use pycairo , has fast native routines drawing. it's antialiased default. implementing drawing algorithms in python slow.

i have image hyperlink. how access "searchredirect" function redirect server side after image clicked? <input id="textsearch" runat="server" name="textsearch" type="text" /> <asp:hyperlink id="searchbutton" runat="server"> <img alt="" src="images/searchbutton.png"/> </asp:hyperlink> protected void searchredirect() { response.redirect("/newproject/home/?searchstring=" + textsearch.value; } rather hyperlink, you'll want use linkbutton , listen click event <input id="textsearch" runat="server" name="textsearch" type="text" /> <asp:linkbutton id="searchbutton" runat="server" onclick="searchredirect"> <img alt="" src="images/searchbutton.png"/> </asp:linkbutton> protected void searchredirect(sender object, e event

i made simplification of double linked list. double linked list structure has head , tail nodes. there function create list , return it. in same function linkage between tail , head nodes. problem when return list(so go outside function), links gone or point nodes of list temporarily created in function. guess correct? if how going bypass problem? here's code: #include <stdio.h> typedef struct node{ /*a node of list*/ int number; struct node *next; struct node *prev; } node; typedef struct list{ /*the list structure holds head , tail*/ node head; node tail; } list; list createlist(){ list newlist; newlist.head.prev=null; newlist.head.next=&newlist.tail; /*first node points second*/ newlist.tail.prev=&newlist.head; /*second node points first*/ newlist.tail.next=null; puts("--create list func--"); printf("head element address: %p\n", &newlist.head); printf("tail eleme

in application asynchronous communication on tcp socket. i don't fact send , receive operations (sync or async) of socket class allowed finish before requested number of bytes transmitted. example: when want read x bytes socket, don't want care how many read operations needed achieve (in application logic). want notified when it's finished (or when error occured). it nice have beginsendfixed, endsendfixed, beginreceivefixed , endreceivefixed. behave beginsend, endsend, beginreceive, endreceive, not call callback before requested number of bytes transmitted. i'm thinking implementing myself, based on: http://msdn.microsoft.com/en-us/magazine/cc163467.aspx in dotaskhelper function call many (synchronous) send or receive until data transmitted. is way go or there different (better) way hide need multiple sends / receives application logic? i recommend using taskcompletionsource class this. has advantage of not burning thread waiting i/o. easier wr
