i want text of listview row (text of item , subitems), not sure if should use lvm_getitem or lvm_getitemtext . what difference between these 2 messages, first retrieve entire information item or subitem while other retrieve text? both lvm_getitem , lvm_getitemtext can used retrieve item's or subitem's text data. since retrieving item's text data common operation, lvm_getitemtext message provided convenience implementation. to illustrate difference, here 2 implementations using either message (error handling elided brevity): std::wstring getlistviewitemtext( hwnd a_hwnd, int a_item, int a_subitem) { std::vector<wchar_t> buffer( 1024 ); lvitem lvi = { 0 }; lvi.mask = lvif_text; // required when using lvm_getitem lvi.psztext = buffer.data(); lvi.cchmaxtext = static_cast<int>( buffer.size() ); lvi.iitem = a_item; // required when using lvm_getitem lvi.isubitem = a_subitem; ::sendmessage( hwnd, lvm_getitem,

nsmutablearray *thisarray = [[nsmutablearray alloc] initwithobjects:@"one", @"two", @"three", nil]; do need delete objects before deleting thisarray? thisarray = null; a nsarray/nsmutablearray keeps reference objects contains, , setting array null automatically releases references. don't have cycle through them release them manually.

i have upgraded php 5.3 5.5 used code: foreach($searcharr $token) { foreach($longtbldef $element) { if (isset($element['th']) && !empty($element['th'])) $query .= "lower(" . $element['td'] .

"%'"; if (next($longtbldef) && !empty($element['th'])) $query .= " `or "; }` if (next($searcharr)) $query .= ") , ("; } in 5.3 , worked fine. when use in 5.5 message: sql error: 1064 -- have error in sql syntax; check manual corresponds mysql server version right syntax use near 'lower(cases_tbl.host) '%dawn%') order cases_tbl.rec_id desc' @ line 6[] this query: select cases_tbl.rec_id "cases_tbl.rec_id", cases_tbl.date_added "cases_tbl.date_added", cases_tbl.status "cases_tbl.status", clients_tbl.client_number "clients_tbl.client_number"

i'm trying create bubble chart using set of data follows: x --> 10 y --> 20 z --> 5 q --> 10 i need have biggest bubble (based on number) @ centre (give or take) , rest of bubbles around without overlapping. all of r examples have seen require 2 dimensional dataset, , since data have 1 dimensional, know if it's @ possible create such graphs in r. it great if suggest me useful hints or so. way task need use sa tools d3js out of options. however, open using tool other r. i wasn't quite sure if question should asked in on stack overflow or cross validated , if moderators believe doesn't belong here, i'll remove it. this should do, main idea being sort value of radius, first biggest, shift values around (odd on 1 side, on other) values decreasing both ways. further explanations in code. library(plotrix) library(rcolorbrewer) # set random seed, reproducible results set.seed(54321) # generate random values radius num.circles <

i have app designed in c#. in simple terms app sends data , image web server takes $_post data , processes it. confess not understand how security end of things work. employ relevant experience wouldn't know ask them @ point in accepted techniques. i assume not simple base64 encode/decode data , needs higher level of encryption. webserver have https ssl(ov) certification on next few weeks limited understanding still need sort of protection/encryption when transferring data users pc web server not listening in on data transfer or that. in simple terms if want keep data secure between users , webserver of common or accepted methods c# php? the data goes directly app on users pc server, control source code both myself , not developer hence lack of technical knowledge on issue. one c# developer talked suggested symmetric/asymmetric algorithm not php developer doesn't know if php can take data , decrypt it. to answer further questions, when server issued , confi

i want add suffix or prefix variable names in data.frame, typically after they've been transformed in way , before performing join. don't have way without breaking piping. for example, data: library(dplyr) set.seed(1) dat14 <- data.frame(id = 1:10, speed = runif(10), power = rpois(10, 1), force = rexp(10), class = rep(c("a", "b"),5)) i want result (note variable names): class speed_mean_2014 power_mean_2014 force_mean_2014 1 0.5572500 0.8 0.5519802 2 b 0.2850798 0.6 1.0888116 my current approach is: means14 <- dat14 %>% group_by(class) %>% select(-id) %>% summarise_each(funs(mean(.))) names(means14)[2:length(names(means14))] <- paste0(names(means14)[2:length(names(means14))], "_mean_2014") is there alternative clunky last line breaks pipes? i've looked @ select() , rename() don't want explicitly specify each variabl

i confused python treats below examples. example 1 >>> = '{}' >>> a.format('1') '1' >>> '{}' >>> example 2 >>> = [] >>> a.append(1) >>> [1] in example 1, 'a' '{}' in example 2, 'a' [1] in both examples, i'm not assigning result 'a', what's difference? answering on broader sense require more detail study particular case difference crops because 1 of object mutable , other non-mutable. you cannot expect call method on string , change it. supposed create new string object. for list.append , because mutable, method call can update list in place.

i'm doing project have compare various gpu cards performance analysis. i had ran same cuda code canny edge detection in both gpu's , found gtx 965 faster(200%) tesla k20. observed tesla c2075 running same of tesla k20. as far know k20 has 2496 cores, 965 has 1024 cores , c2075 has 448 cores. k20 , c2075 nvidia kepler architecture , 965 maxwell architecture. what i'm doing wrong or there difference in hardware part causing problem? also, can check power consumed graphic card using program or theoretical calculations? many cores not mean shorter execution times. if cuda app utilizing single thread , run app on: k20, has lots of cores 706mhz frequency, as opposed gtx965 has half of them working on 944mhz ... gtx965 can work faster. in theory, long utilizing less 1024 cores app, gtx can outperform k20, in case if memory not bottleneck k20 has: bigger memory bandwidth, much more memory in general, a tiny bit higher memory clock. so, sum up,
