i have 1 ant project xyz , want, when put project 1 random workspace, , when build xyz automatically add workspace folder config (already present in workspace) , task (already present in workspace) classpath dependent project. well, if projects in workspace follow same standard classfile folder, let's project/build : project1/ build/ class files... project2/ build/ class files... project3/ build/ class files... xyz/ build.xml .. set classpath in xyz/build.xml this: <project basedir="."> <path id="my.classpath"> <dirset dir=".." includes="**/build"/> </path> <javac classpathref="my.classpath"> ... </javac> </project> in way, of .class files produced in every project else in workspace included in compilation of xyz. in case know projects want include in xyz's classpath, have set this: <projec

i struggeling simple problem last 3 hours. rewrote class , replaced 2 string parameters lists. problem is, when calling rekursive method add 1 character first string parameter. , when length of parameter hits length of 7 prints out. string never gets longer 7. replaced integer list since string consisted of numbers. list though keeps getting longer , longer , have no idea why. hope explained properly. if not, ask me please. the question super easy answer guys. here first class, works. package uebung4; public class permall_alt { static int counter = 0; private static void permutation(string word, string str) { int n = str.length(); // system.out.println(str + " str"); // system.out.println(word + " word"); if (n == 0) { if ( (integer.parseint(word.substring(0, 1))) > (integer.parseint(word.substring(1, 2))) && (integer.parseint(word.substring(1, 2))) < (integer.parseint(word.substring

how can convert float number string? for (float = 1000000000; < 10000000000; i++) { //temp never change , it's value 1000000000 string temp = convert.toint64(i).tostring(); } this number big , want save string on file like 1000000001 1000000002 1000000003 how can convert float number string? obviously: i.tostring() . see the documentation learn how apply formatting in order achieve desired output. however, couple notes: a variable named i commonly indicates int , not float . iterating for , variable of type float obscure. are sure want use floating-point data type, when treat integer? consider using long or decimal . temp never change , it's value 1000000000 float 's precision not enough store number big 1000000000 , discards least significant places. wikipedia : “all integers 6 or less significant decimal digits can converted ieee 754 floating point value.” that's why result seems same. side effect, for c

my code: #inlcude <math.h> #include "draw.h" /*int draw(int x, int y)*/ draw(rintf(10 * x), rintf(8 * y)); i warning: conversion ‘int’ ‘float’ may alter value. i can't change draw float, since need draw points. rounding inevitable. ideas? the return type of rintf float produces warning. can either explicitly cast int suppress warning (i.e., (int) rintf(10 * x) , or use way of rounding (e.g., if values known non-negative, (int) (10.0f * x + 0.5f) ) or lrint (preferably tgmath.h ), although returns long may cause warning depending on compiler , settings.

i want run several process in parallel without giving cpu work cpu can other jobs. in python, use os.system call binary. , theses call independent , can parallel. these binary may run different length of time. what want example, keep 8 of them run in parallel, if 1 exit early, start one. what doing this: count = 0 f in files: count = count + 1 cmd = exe if (count != 8): cmd = cmd + " &" else: count = 0 os.sytem(cmd) but not ideal if cmd without & runs long or short. i tried multiprocessing module, p=pool(8) print(p.map(f,list_of_args)) but in case not running 8 processes in parallel of time. since of them exit early. there no need synchronization. i have 16 cpu cores , want half of them(8 processes runs in parallel) you'd better not use os.system subprocess.popen more powerful , safe. subprocess.popen not block on call don't need append '&' @ end of command. for question it

how, can keep date format same of excel @ time of download in different-2 time zone? my downloaded file contains date column format mm-dd-yyyy. issue that, while downloading excel file in region not converting dates different formats, while downloading same file in uk region, converting dates dd-mm-yyyy. date 12-01-2015 converting 01-12-2015. i want keep date format of excel file mm-dd-yyyy in regions. generating file using asp.net c#. thanks in advance. this because excel selecting different date format based on program's locale setting. imagine options are: a: change cell format need in each location, e.g. in vba code selection.numberformat = "m/d/yyyy;@" b: store date data in text format. literally text string in mm-dd-yyyy format. still parse later.
