what i'm trying achieve in wp 3.1.x using wp_nav_menu function, have menu such as: -- category 1 -- category 2 -- category 3 -- category 4 -- category 5 -- category 6 but when you're on 'category 2' displays as: -- category 1 -- category 2 -- sub category 1 -- sub category 2 -- sub category 3 -- category 3 -- category 4 -- category 5 -- category 6 ps. i'm not looking css hide/show functionality, can achieved easily. pps. possible solution extending walker_nav_menu class? if subclass walker_nav_menu class can override display_element function , conditionally remove item's children before looped through. if (!$element->current && !$element->current_item_ancestor && isset( $children_elements[$id])) { unset( $children_elements[ $id ] ); } this remove children of item not current, need check item's type if want categories. complete walker this: https://gist.github.com/954627

i writing c application takes user input , few database queries. aware of risks here of sql injection , wish prevent it. ideally use parameterized queries, have been unable find functionality in c far. constructing queries such: char *query; asprintf(&query, "update sometable set somefield='%s';", userinput); if unable this, must need filter user input. how should filtering done? enough remove 's , "s? (valid inputs cannot contain them). if so, easiest way of doing in c? i believe want use prepared statements , parameter binding. not directly interpolate user data queries. see mysql manual info on this.

ive been playing orm caching in past few days , 1 thing confusing me lot sql still logged (when have logsql = true) console caching enabled. makes me think caching not working, think hibernate doesnt create sql since sees object in cache, maybe hibernate generates sql before checking ehcache. my code below incase picks missed. application.cfc this.ormsettings.secondarycacheenabled = "true"; this.ormsettings.cacheprovider="ehcache"; this.ormsettings.logsql=true; then books cfc component persistent="true" entityname="books" table="db_books" cacheuse="transactional" lazy="true" and lastly code im using call. = entityloadbypk("books","1"); writeoutput(a.getname()); from i've read , experienced first hand, sql transferred on wire dbms logged regardless of whether coldfusion orm (hibernate) generating jit, or pulling cache. if anything, run few benchmarks identify whe...

how n numbers after comma in java? ... double numb = 123.45; void lastnumber(int n){ // here } ... (in example n = 2, 2 numbers after comma) a bit ugly: public long getfraction(double num, int digits) { int multiplier = powers_of_ten[digits]; long result = ((long) (num * multiplier)) - (((long) num) * multiplier); return result; } where powers_of_ten array of precomputed powers of ten (0=1, 1=10, 2=100, 3=1000, etc.)

if have instance of object in javascript, seems can difficult find actual type, ie var point2d = function point2d(x, y) { return { x: x, y: y } } var p = new point2d(1,1); typeof p // yields 'object' not 'point2d' one way around found make object own prototype, , can gets name calling prototype.constructor.name, var point2d = function point2d(x, y) { return { x: x, y: y, prototype: } } new point2d(1,1).prototype.constructor.name // yields 'point2d' would ok way of doing (what pros/cons?) or there better practice missing out on? thanks. first need fix how building class, since tripping in js pitfalls , doing weird stuff: function point2d(x, y){ //our constructor/initialization function //when run, 'this object have //point2d.prototype prototype this.x = x; this.y = y; //don't return value here! doing overrides //the default "return this" want. } //you can put ...

i have implement requirement java crud application users want keep search results intact if actions affects criteria returned rows matched. confused? ok. let me give familiar example. in gmail if advanced search on unread emails, presented list of matching results. click on entry , go search list. happens have read entry hasn't disappeard original result set. line has changed bold normal. i need implement exact same behaviour application designed in such way transaction persisted first , ui requeries db keep in sync. complexity of application , size of database prevents me doing simple in memory caching of matching rows , making changes both in db , in memory. i'm thinking of solving problem on database level creating intermediate table in oracle database holding pointers matching records , requerying records keep ui in sync data. ideas? in oracle, if open cursor, results of cursor static, regardless if transaction inserts row appear in cursor, or updates or ...

i assumed answer simple @ moment seems alluding me. i'm using mersenne twister (implementation here http://www.bedaux.net/mtrand/ ) generating random numbers. i need able generate same sequence of "random" numbers twice, straight after each other in same program. i'm using same void seed(const unsigned long*, int size); function same set of values in hopes reset generator , allow me generate same values again. specifically: unsigned long init[4] = {0x123, 0x234, 0x345, 0x456}, length = 4; irand.seed(init, length); just tested , working. i wondering if has had problem before. or knows i'm doing wrong. unsigned long init[4] = {0x123, 0x234, 0x345, 0x456}; int length = 4; mtrand_int32 irand(init, length); irand.seed(init, length); // resets i've tested modifying mtrand test program reset after 5 numbers of output , results clear.
