i did dumb. i'd imported create tables sql file twice. that's not worst part however. proceeded trying drop duplicate tables phpmyadmin database. loads when click on phpmyadmin now: error sql query: edit select `tables` `phpmyadmin`.`pma_recent` `username` = '[myusername]' mysql said: #1146 - table 'phpmyadmin.pma_recent' doesn't exist as in, above on otherwise blank, white page. edit returns normal when comment out "advanced features" section in config.inc.php file (the red exclamation signs still beside everything, i'm starting wonder if that's default icon choice phpmyadmin 4.0.1). once uncomment them, above returns. i've noticed tables seems empty (maybe reason exclamation signs?). mean anything? check whether tables inside phpmyadmin database have 2 underscores __ after pma prefix. if case, update entries in config.inc.php additional underscore.

i'm building app in phonegap. app makes heavy use of javascript , has content area should scrollable. need use touchstart , touchend events. the problem that, unless use e.preventdefault on touchmove/touchstart, touchstart event once , never again after (not useful). if e.preventdefault() on either of two, native scrolling disabled (on mobile devices). how allow native scrolling while listening touchstart + touchend? failing that, simulate native scrolling (using touchmove?)? i've tried hand @ myself, , result of frankly terrible.

i want button1 change text of form1 "my application name" "my application name2" click of button. what i've tried: form1.text = (textbox1.text) but no luck. any help? you cannot can change form name @ run time. name of form can want, must stay same throughout. can't imagine why ever want change name in runtime not visible users. form's caption on other hand completly different thing, adressed in @matzone's answer.

i have been following tutorial video shows how run jersey server ( edit: jax-rs server via apache wink, see accepted answer) in osgi. short video , process seems clear. i'm not clear on how helloworldresource loaded jersey. helloworldresource registered osgi container service using apache felix dependencyactivatorbase (which works great). gather apache felix whiteboard supposed somehow magically map jersey resource, when go run 404. i know service mapped correctly shows in console when issue 'services' command. know server running or wouldn't 404 not found. i've double checked bundles , believe installed correctly. any hints appreciated. first of all, amdatu not based on jersey. jersey 1 of many jax-rs implementations available. amdatu based on apache wink. shouldn't matter however, since should programming standard anyway. amdatu looks services registered object.class in service registry, , checks if registered service annotated @pat...

given outcome of applying canny edge detector image using cv2 python library, want dilate edges internal part of convex boundaries using morphological operators. kind of structure element should use that? late answer, here simple trick: you duplicate image you put 0 outside convex boundaries, inner pixels used during dilation you apply dilation you compute maximum between original image , dilation result. you can use structuring element of choice. square little bit aggressive, when ball preserve euclidean distance.

i fiddled around loops, , tried head around of logical part of it. while i'm far beyond level of loops @ point, still tend bit weird when comes logic sometimes. however, found incremental value of loop different depending on whether inside or outside loop: int i; for(i = 0; < 10; i++) { system.out.println(i); // 0 ... 9 } system.out.println(i); // 10 now, i'm afraid 1 day i'll come point i'll have use counter more matching against condition... now think understand why happening; being incremented after condition fails , loop dies, supposed happen? is there mathematical/logical (or elegant) way not make go n+1 after loop termination, i'm missing here? that how loop works: check condition, if holds go 2, else terminate; run body; execute modification, go 1. so in word, cannot. also, how loop terminate if variable not go n + 1 ? in case, loop condition holds, run forever.

i want set global variable via set function sets undefined value: var name; var setname = function(name){ this.name = name; } in case don't use this . (it work not necessarily. why? read this ) just use: var name; var setname = function (aname) { name = aname; } also make sure code not inside of scope (function): function foo() { // ... var name; var setname = function (aname) { name = aname; } // ... } in case name not global , have omit declaration make global: function foo() { // ... var setname = function (aname) { name = aname; // not global, if not defined in visible scope } // ... } but bad practice, try avoid polluting global namespace . variable considered in global namespace if: it has no var ( name = ... , , there no other visible local variable called name it set on window (e.g. window.name = ... )

i have few modules in python, imported dynamicly , have same structur (plugin.py, models.py, tests.py, ...). in managing code want import submodules, example models.py or tests.py not mandatory. (so have plugin_a.plugin , plugin_a.tests plugin_b.plugin ). i can check if submodule exists by try: __import__(module_name + ".tests") except importerror: pass that fail, if module_name+".tests" not found, fail if tests -module try import something, not found, example because of typo. there way check if module exists, without importing or make sure, importerror raised 1 specific import-action? you know import error message if module doesn't exist check that: try: module = module_name + '.tests' __import__(module) except importerror, e: if e.args , e.args[0] == 'no module named ' + module: print(module, 'does not exist') else: print(module, 'failed import')

i have requirement need attach audio/video media submitted binary files embedded pdfs residing on server. btw, audio/video binary coming mobile app. is there pdf library out there allows embedding audio/video in pdf? also, need these media embedded in simplest form when pdf containing media opened on target device, there should no need installing additional media decoders. my server side environment in .net/c# need pdf library compatible .net almost pdf .net supports movie annotations, itextsharp (open source), tallpdf, xfinium.pdf (i work company), pdf4net, docotic.pdf, name few. thing media files embedded (converting video not job) , target machine must have required codecs in order play media. if have control on media format, can choose format supported many platforms.

i did not find suitable answers on web, post question here. __block int test = 1; dispatch_async(dispatch_get_main_queue(), ^{ test = 2; }); nslog(@"%i",test); this code result in console message "1". __block nsstring *test = @"no"; dispatch_async(dispatch_get_main_queue(), ^{ test = @"yes"; }); nslog(@"%@",test); this code result in console message "no". why so? thought __block identifier should solve problems in case. hypothesis local variable copied , code inside block hadn't modify outside itself. how can modify local variables inside dispatch_async? sorry if noob question. you dispatching asynchronously main queue. the dispatch_async returns before block executed (coincidentally). to underscore how non-deterministic concurrent programming can be: note nslog() might see new value maybe once in blue moon. might not ever see in debugging environment, customer might encounter b...

from docs : bit-and-not function usage: (bit-and-not x y) (bit-and-not x y & more) bitwise , complement added in clojure version 1.0 clojure's other bit- functions make sense me, don't understand one. it equivalent this: (bit-and x (bit-not y)) this function can used subset tests. set a (represented bitmask) subset of set b if , if (bit-and-not b) zero.

first , last labels rendered incorrectly. know if there's way fix this, or bug? here's how it's rendering me http://i.imgur.com/f4i9fjl.png the solution can change depending of elements you've inside body tag. i've selected .nv-x .nv-axis elements inside <body> . line defines attr option, can change de translate , rotate values. var chart = nv.models.discretebarchart(); nv.addgraph(function() { ...
