i have implemented small viewdidload() show picture autoresizing, doesn't work, please me , mistake in code in line 3 , 4???? imageview = [[uiimageview alloc] initwithimage:img]; imageview.frame = self.view.frame; imageview.autoresizingmask = uiviewautoresizingflexibleheight; imageview.autoresizingmask = uiviewautoresizingflexiblewidth; i hope me? if im not mistaken should following way: imageview.autoresizingmask = ( uiviewautoresizingflexiblewidth | uiviewautoresizingflexibleheight ); the way it, override autoresizingmask.

is developping ejb application considered web services ? or 2 different ? or can make ejbs web services ? my answer yes , no. no in sense ejb programming model . programming model contains concepts such security, transaction demarcation, state management , persistency (stateful or stateless beans), , more. while web service more remoting technology , is, way connect systems, soap in case of web service. under perspective both different topic (web service compared rmi-iiop though). yes in sense both referred technologies expose service outside (as long it's stateless). under perspective belong same category. , ejb can indeed exposed web service annotating bean accordingly. hope brings light distinction.

we have web application in users perform ad-hoc queries based on parameters have been entered. might mention response time of high importance users. the web page dynamically construct sql execute based on parameters entered. example, if user enters "1" "business unit" construct sql this: select * fact business_unit = '1' --and other criteria based on input params i found user not specify business_unit following query constructed select * fact business_unit '%' --and other criteria based on input params imho, unnecessarily (if not grossly) inefficient , warrants sending code bad modification since have higher rate of sending code rework others, believe may earning reputation being "too picky." if inappropriate question because not direct coding q, let me know , delete immediately. confused whether subjective questions allowed or not! i'll watching replies. ty update: i using oracle database. my impression orac...

all our developers using vs2010 professional code analysis not available. want them use fxcop analyze code before checking in. have gone through rules , disabled bunch of them , added couple of them. want developers use same set of rules since rules used in msbuild. how distribute rule set used in fxcop? files need distributed , supposed go to? when using stand-alone fxcop, can create fxcop project file (with extension .fxcop) contains list rules used in analysis. (typically, file include list of target assemblies, although optional.) file may checked source control code in order distribute developers working on shared code base.

i have text this. every person haveue280 sumue340 ambition i want replace ue280, ue340 \ue280, \ue340 regular expression is there solution thanks in advance something this? string s = "every person haveue280 sumue340 ambition"; // put backslash in front of all "u" followed 4 hexadecimal digits s = s.replaceall("u\\p{xdigit}{4}", "\\\\$0"); which results in every person have\ue280 sum\ue340 ambition not sure you're after, perhaps it's this: static string tounicode(string s) { matcher m = pattern.compile("u(\\p{xdigit}{4})").matcher(s); stringbuffer buf = new stringbuffer(); while(m.find()) m.appendreplacement(buf, "" + (char) integer.parseint(m.group(1), 16)); m.appendtail(buf); return buf.tostring(); } (updated according axtavt nice alternative. making cw.)

i apply style every row in table except specific row (could first, or 1 unique class or id - doesn't matter). how do that? the easiest cross-browser way apply style override it, this: table tr td { background: blue; } table tr.someclass td { background: none; } since 1 class, id, etc more specific, it'll have different styling...just put whatever properties you're setting rows in selector overrides/reverses styling. benefit of approach doesn't need partially supported (css3) selectors, works in browsers.

the notorious error haunts me in app store: "the binary uploaded invalid. signature invalid, or not signed apple submission certificate." steps i've taken: 1) i'm using monotouch / monodevelop. 2) app works on iphone simulator , on device. 3) i've made distribution build according examples in monotouch documentation (using distribution profile). 4) i've checked xxxx.app package contains file "embedded.mobileprovision". 5) i'm zipping (in os x gui) app bundle (only xxxx.app file). 6) i've checked integrity of xxxx.app file command "codesign -vvvvv xxxx.app" 7) i've cleared keys , profiles xcode organizer , keychain, , added keys/profiles again. no luck. ideas? /pom make sure you're using provisioning profile app store (not ad hoc distribution) then select profile when building app.

i know need root access if want capture screenshot using background application. possible grab screen content of current visible activity owned process? not seem security constraint since user has installed app using app. if how work? the thing can imagine work (not tested) instance of root layout node , manually call draw(canvas) own canvas instantiated empty bitmap , save bitmap. sounds lot of work thing can think of @ moment.

the "echo" below failing , retarded figure out why. trying echo of array members in loop. #!/bin/bash foo=bar1,bar2 in ${foo//,/" "} declare -a ${i}='(null null null null)' echo ${i[*]} done thanks help! try eval "echo \${$i[*]}" why doing way? there easier , more direct way whatever ultimate goal is. if describe it, perhaps can avoid unnecessary complication.

if set on nszombie, tells me i'm releasing object released , gives me memory address, helpful... can't see object it's... because app stopped working... any help? thank you you looking for: malloc_history http://www.friday.com/bbum/2010/01/10/using-malloc-to-debug-memory-misuse-in-cocoa/

i have written code in matlab modulate , demodulate signals. deploy them using deploytool , .jar works in 1 application without gui gives me undefined variable "modem" or class "modem.pskmod". in application gui. basically, want know cause error occur have around, don't find documentation on error. as don't understand why work in 1 application fails in when code use similar when calling method. ok, after testing , comparing difference between application without gui , application gui. found solution problem. as application without gui run init method start of application (there 1 thread) import matlabfunction.*; public static void main(string[] args) { matlabfunction test = new matlabfunction(); test.runfunction(1, lstabc.toarray()); } but in code gui run init method within jframe (main() contain init code) inside edt public static void main(string[] args) { swingutilities.invokelater(new runnable() { public...

let's imagine html-form with 2 submit buttons. 1 of them positioned in upper half of form , less important. other button actual submit button, saves entered data. button positioned @ end of form. 2 buttons trigger different action-urls. experienced users submit forms pressing "enter" or "return" instead of clicking on according button. unfortunately, browser first submit-button of current form , use execute form-submit. since in form second button actual submit-button, need tell browser use particular button (or action-url associated it). i don't link javascript listeners, looking key pressed or that. i'm looking better approach problem. however, javascript or jquery solutions (without keypressed-listerner) welcome. thank in advance. you could, theoretically @ least, have 3 submit buttons in form. button 2 existing 'less-important' button (from halfway down form), button 3 existing 'actual-submit' button existing f...

i've been using c# while, , have started working on adding parallelism side project of mine. so, according microsoft, reads , writes ints , floats atomic i'm sure these atomicity requirements workout fine on x86 architectures. however, on architectures such arm (which may not have hardware floating point support), seems these guarantees hard. the problem made more significant fact 'int' 32-bits. there many embedded devices can't atomically perform 32-bit write. it seems fundamental mistake in c#. guaranteeing atomicity of these data types can't done portably. how these atomicity guarantees intended implemented on architectures there no fpus or 32-bit writes? there 2 issues regard "portability": can practical implementation of language produced various platforms will program written in language expected run correctly on various platforms without modification the stronger guarantees made language, harder port various platform...
