what difference between friend function , friend class? , should use of friend keyword? in short, 1 class , 1 function. function, 1 function gets access private members. class, whole class , functions access private members of befriended class. the friend keyword used grant access private data members. @ times may need helper class or complimentary class access private members of different class. functions, common example operator overload. perhaps want overload + operator. may make operator+ function declared outside class (so can called without object) , need access private class data. check out this site detailed description of both , how use them.

(i tested qt 4.6 tp1. not sure whether issue fixed in release, cuz did not have time compile release version on laptop developing toy feed reader.) any advice? :) i read following qt 4.6.0 changelog : qurl's parser more strict when hostnames in urls. qurl enforces std 3 rules: each individual hostname section (between dots) must @ 63 ascii characters in length; only letters, digits, , hyphen character allowed in ascii range; letters outside ascii range follow normal idn rules that means qurl no longer...

my problem this: need determine timestamp of first , last email sent exchange account every day mail exists for. also, each day need rank words appear in each email can report trend words each day. i have 2 approaches i'm considering, , welcome comments , suggestions relating either these approaches or entirely different. i've discounted exporting file outlook csv file include time stamp fields in output, crucial factor me. approach #1 is: use perl , net::pop3 pull messages out of inbox, mung them , insert them mysql database. approach #2 is: use win32:ole attempt act proper exchange client, same end. if use win32::ole you'll have either use outlook automation or cdo libraries. i've done both in previous life, , works, it's bit painful. i'd suggest approach #1 except can't imagine exchange allow fetch sent mail through pop. rather, though, exchange can enabled expose imap interface, , imap should let @ sent mail without running o...

i'd work on sip project mobile devices. i've seen links siphon, sipdroid , opensips. does opensips allow me make phone calls between 2 ios devices in local network? in other words, i'm trying app voip company. i'd set own sip server , use theirs later. there reason not work? opensips sip server application includes variety of components needed sip infrastructure such registrar, proxy, presence agent etc. opensips not sip user agent (or @ least not 1 that's designed work person end user). means it's not built make or receive calls. if planning on using opensips sip proxy on network combined different piece of software, such sipdroid, acting user agent on mobile devices answer question yes. able configure opensips allow calls between devices on same local network.

<bean id="ntlmfilter" class="org.springframework.security.ui.ntlm.ntlmprocessingfilter"> <security:custom-filter position="ntlm_filter" /> <property name="stripdomain" value="true" /> <property name="defaultdomain" value="company" /> <property name="domaincontroller" value="192.168.1.1" /> <property name="authenticationmanager" ref="_authenticationmanager" /> </bean> may know how set failover second controller? unfortunately, ntlm isn't supported spring 3. if using secondary domain controller critical requirement application, think you'll need jcifs source. jcifs doesn't want support ntlm anymore either. old libraries out there. i've hacked around app invisibly authenticate users whether they're domaina or domainb. it's possible, although possibly bit daunting.

i have registration form customer selects desired package via dropdownlist. select whether wish avail of multiyear discount choosing yes or no radio buttons. if yes radio button selected, dropdownlist shown (using javascript) selection of years 1-3. i'm not familar @ javascript, , need next when customer selects year 1, 2, 3 multiyear discounts, calculate discount, , show in label beside dropdownlist or hide label if customer has selected no multiyear discounts. here existing code: javascript hide yearly discount dropdownlist <script type='text/javascript'> $(function(){ $('#discountselection').hide(); $('#no').click(function(){ $('#discountselection').hide(); }); $('#yes').click(function(){ $('#discountselection').show(); }); }); </script> and here html code: <td width="343">package*</td> <td colspan="4"> ...

i have editable datagrid in flex, data full of numbers. columns have no special itemrenderer, labelfunction, returns number as-is if positive, puts in parentheses if negative, so 27.3 => "27.3" -27.3 => "(27.3)" now, these cells editable. when try edit cell positive number, nothing wrong. if try edit negative number, starts editing (27.3) instead of editing -27.3 . because of this, when edit done, labelfunction evaluated new value in parentheses(i.e., labelfunction called "(30.5)" ), , converting number results in nan . so, want know if can make datagrid edit data in dataprovider instead of label shows. i hope clear condition. please ask if need clarification. thank you. is you're after? example: modifying data passed or received item editor - livedocs.adobe.com (you may still have scroll down once page loads... anchor doesn't seem working me.)
