i quite beginner ssis packages bear me. trying do: i have daily files in format of yyyy-mm-dd_filename_bla_bla.tsv date of file need added in table trying import it. doing manually derived coloumn expression: (dt_date)(dt_dbdate)"yyyy-mm-dd" is there possibility automatically take file name , take date part import table. the things find on internet getting date file name, opposite. i hope provided enough information, , can me out problem. thanks in advance. if know file name keep file name in variable example let file name : 01/02/2015_kjh.bgd then using derived column use string functions left(@variable,10) 10-> length of date then map oledb destination

i'm new matlab, , working on program deals frequency of human voice based on microphone input. biggest problem running musical notes (what dealing in project) increase in frequency exponentially, 1.059463^x each semitone in musical scale. in program dealing with, need both scale graph detected frequency close note number corresponds scale data can work note numbers in terms of notes , musical cents frequency graph can converted midi data. other option have found has been create library of frequencies recorded frequencies compared to, unnecessarily complicated , time consuming. so, in essence, trying scale data a2, frequency of 110hz, correspond note number 45. there way this? i think want: f = 110; %// frequency in hz n = log10(f/440)/log10(2)*12+69; %// 440 hz (note a4) note 69 note = round(n); cents = round((n-note)*100); examples: f = 110 gives note = 45 cents = 0 f = 345 gives note = 65 cents = -21 in accordance this reference , th...

i set variable spaces in string new bash: var='my variable spaces' /bin/bash and if want start new bash same environment, like: env=$(cat /proc/self/environ | xargs -0 | grep =) env -i - $env /bin/bash but thing is, in /proc/self/environ , variable without quotes. last command throws a: env: variable: no such file or directory how can work around limitation? ps: simplified version of following issue: https://github.com/jpetazzo/nsenter/issues/62 i think answer here not use shell script set things up. using higher-level language makes easier parse /proc/<pid>/environ useful. here's short example: #!/usr/bin/python import os import sys import argparse def parse_args(): p = argparse.argumentparser() p.add_argument('pid') p.add_argument('command', nargs=argparse.remainder) return p.parse_args() def main(): args = parse_args() env = {} open('/proc/%s/environ' % args.pid) fd: env...

i want close pop , refresh parent after few seconds delay make sure data received. have following function closeandrefresh(){ settimeout(function() { window.open('/{!currsubid}','_top'); window.location = window.location.href; return true; },5000)} this code refreshes parent inside popup, pop not close, rather parent shows refreshed - in pop up so move pop outside of timeout, give name, call close, , reload. function closeandrefresh(){ var winpop = window.open('/{!currsubid}','_top'); //load pop give name window.settimeout(function(){ winpop.close(); //close pop window.location.reload(true); //refresh current page },5000); } you use ajax call server , not have deal pop , wondering if pop blocker block or not knowing if call completetd. when call comes call, can reload page.

i think "call" instruction kind of "jump" instruction. "jump" instruction have address go. , "call" instruction either should have target address. when disassemble binary, "call" instruction have lable of target function. then, how know go? in other words, can found target address of each function? x86, arm whatever. the addresses in assembly programming labeled symbolic names. , true not call instruction other instructions. there reason approach - addresses depend on in memory program loaded. also, instructions contains not address itself, offset, relative current address program executed. on other hand, programmer doesn't care exact value of address. want know address placed. why symbolic labels used. using symbolic labels meaningful names improves readability of source code , makes program easy support , extending. these symbolic addresses (labels) translated numbers during assembling of source code executabl...

my experience until when dealing styles has been create style.xml file , create properties want style. if want style based on existing style, use parent attribute. specify style inside of layout file on controls want apply style to. where @ loss when want use system styles , update properties. wondering whether can leave layout files alone , not bother applying styles controls. instead, somehow update property of system style , update everywhere in app style being used default. more specifically, want change background color of actionbar haven't found way of doing other way described above. you're looking themes, collections of styles, applied either globally throughout application, or each activity in particular. start this document , investigate further.

what correct way use int* x ? mention related link if possible unable find one. a string literal creates array object . object has static storage duration (meaning exists entire execution of program), , initialized characters in string literal. the value of string literal value of array. in contexts, there implicit conversion char[n] char* , pointer initial (0th) element of array. this: char *s = "hello"; initializes s point initial 'h' in implicitly created array object. pointer can point object ; not point value . (incidentally, should const char *s , don't accidentally attempt modify string.) string literals special case. integer literal not create object; merely yields value. this: int *ptr = 42; // invalid is invalid, because there no implicit conversion of 42 int* int . this: int *ptr = &42; // invalid is invalid, because & (address-of) operator can applied object (an "lvalue"), , there no object apply to...

i trying support authenticated proxies in java application. understanding java.net.proxy class not support authentication, , need handle authentication yourself. i have created subclass of java.net.proxy class, takes 2 additional parameters, username , password. implementing http proxy authentication quite easy, , method gethttpproxyauthenticationheader returns base64 encoded auth info, pass httpurlconnection or similar. i'm having trouble sock proxies though. cannot find documentation on sending authentication socks server. i'm unsure if need implement socks authentication protocol in class using method such authenticatesocksproxy(outputstream stream), , call authedproxy.authenticatesocksproxy(outputstream); before using socket like outputstream.writebytes(mydata.getbytes()); another option return byte[] of authentication data , write data manually, instead of class writing authentication data. i not think java.net.authenticator, or system.setproperty metho...

(think flappy bird screen moves up) in motionevent.action_down:, can't use canvas.getwidth() or parameters see user touched. thanks , :) to user touched you'd use event.getx() , event.gety(). wouldn't use canvas operations @ all.
