alright trying this. i have account class, have checkingaccount , savingsaccount class inherit account class. in program have array called accounts. going hold objects of both types of accounts. account** accounts; accounts = new account*[numaccounts]; accountfile >> tempaccountnum >> tempbalance >> temptransfee; checkingaccount tempaccount(tempbalance, tempaccountnum, temptransfee); accounts[i] = tempaccount; i error when trying assign tempaccount accounts array. no suitable conversion function "checkingaccount" "account" exists. how make accounts array hold both kinds of objects? each element in accounts account* . is, "pointer account ". you're trying assign account directly. instead, should taking address of account: accounts[i] = &tempaccount; remember pointer pointing @ invalid object once tempaccount has gone out of scope. consider avoiding arrays , pointers. unless have reason not to, us

how convert this: [ {food: 'apple', type: 'fruit'}, {food: 'potato', type: 'vegetable'}, {food: 'banana', type: 'fruit'}, ] into this: [ {type: 'fruit', foods: ['apple', 'banana']}, {type: 'vegetable', foods: ['potato']} ] using javascript or underscore assuming original list contained in variable named list : _ .chain(list) .groupby('type') .map(function(value, key) { return { type: key, foods: _.pluck(value, 'food') } }) .value();

the smtpclient class states instance members not thread safe. can seen if concurrent calls made send or sendasync . both methods throw invalidoperationexception on second call if first has not yet completed. the method sendmailasync , introduced in .net 4.5, not list invalidoperationexception thrown exception. new .net 4.5 methods implement sort of queuing? reflector isn't able shed light on implementation details of class, assume has been implemented in native methods. can multiple threads call sendmessageasync method on shared instance of smtp client safely? i'm not sure why using reflector didn't work you. if decompile it, see following code: [hostprotection(securityaction.linkdemand, externalthreading=true)] public task sendmailasync(mailmessage message) { taskcompletionsource<object> tcs = new taskcompletionsource<object>(); sendcompletedeventhandler handler = null; handler = delegate (object sender, asynccompletedeventa

i need read txt file part part... example, in txt file: (age,5char_name) 17susan23wilma25fredy i need read firstly 17susan . in other words, first 7 characters , after 23wilma , 25fredy , i'm not reading whole file , substring file record. there way via streamreader? records 7 bytes... 2 bytes age, 5 bytes name , records in line. there no jump next line. i think there solution: dim filestream new filestream("\records.txt", filemode.open) dim streamreader new streamreader(fs) dim buffer(7) char bw.readblock(buffer, 0, 7) console.writeline(buffer) this read first 7.. can read other via loop or for..

i have upload location users can update portion of database uploaded file. files 9gb, inserting 150,000,000 lines can take few minutes. after clicking button on website update database, php (using mysqli) goes on mysql lock down. if open other tabs, nothing until large update complete. however, know it's not locking database/table, because cli can still "select count(*) table" , gives me result right away. what best method of inserting 150,000,000 records while still letting other php pages access db (for reading only)? you can use "insert delayed". delayed option insert statement mysql extension standard sql useful if have clients cannot or need not wait insert complete. common situation when use mysql logging , periodically run select , update statements take long time complete. you can read resource on official documentation here . ;-)

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610

alright, people of stack overflow, have question you: in web design class @ high school , learning ahead of class since knew first half of class. asked teacher if teach have learned javascript , agreed. however, 1 of things wanted me teach not working me when try out on own. trying simple check variable when input name box, if name or teacher's name pulls popup says "welcome" or that, , if else says "go away" issue no matter try in code not working. test function have @ moment; intended print out <!doctype html> <html> <head> <script type="text/javascript"> var name = document.kageform.user.value; function validator(){ alert(name); } </script> </head> <body> <form name="kageform"> username:<input type="text" name="user"> <br/> password: <input type="password" name="pass"

i create function keep_running define based on input either sensitive time had been running or number of iterations. can't seem come pythonic way iterations without decrementing counter outside of function, e.g.: def keep_running(ttl): return ttl > 0 ttl = 1 while keep_running(ttl): do_stuff() ttl -= 1 is there better way this, preferably within function keep_running ? the best way manage state inside class. initialize object loop_context ttl value, , loop condition loop_context.keep_running() .

if had master list of million items, , list of million users, , each user had custom sorted subset of 50 items, immediate way model like: items [itemid] : { name : 'aaa', description : 'bbb', ... } ... users [userid1] : { name : 'john', token : 'xyz', sorteditems : { itemid1 : xx, itemid2 : xx, ... } } each user own collection of sorteditems in whatever order needed. problem have have multiple requests per item full item data. after handling updates sorted list, need query master list item data. not big deal, recommended? another strategy duplicate item data in both master list , sub-lists (or rid of master list). way data right there when need it. obvious problem synchronization. happens if property of item changes? you'd have loop through every user's sorteditems list , update each instance - recipe serious data inconsistencies. thoughts?

part of project i'm on has gui app built netbeans using gui design tools come in ide. but part of bigger project, , needs built in environment not have netbeans installed (it happens gradle-based build on jenkins). i've gotten builds (seemingly) work, keep running inexplicable run-time errors (i.e., dependencies appear met identical jars on classpath , on, attempts read resources project jar fail.). from googling around, looks might have compiling .form files , including dependency resulting java. (though, netbeans build not add jars above our gradle build adds). so question is... can done? or proper build rely on hidden build-time mojo that's going on in netbeans? yes, can compile classes without netbeans. sure not netbeans library, absolutelayout . .form files netbeans showing components matisse, generated code in .java file.

i have following practical work complete learn c++, i've been spending long time looking answer , reading through work i'm bit confused clarification of going wrong here. code looks below: safearray& safearray::operator =(const safearray& other) { //add code here return *this; } we have implement code assigns 1 array another. if understand code correctly method takes formal parameter of constant "safearray" called other. & after safearray means actual array passed , not copy while const means can not changed. method returns actual array , not copy of it. as such thought simple case of creating pointer, referencing memory location of "other" , returning de-referenced result. in attempts code thought i've had no luck. i tried doing following: safearray* ptr = &other; //this should have created safearray pointer memory location of array "other". the problem here error: main.cpp:31:23: error: invalid conversion ‘c

i need understanding fundamentals of scrolling on items drawn canvas in android. suppose want create timeline time @ 0 top of visualization , time increased timeline continues rendered below previous point. if wish render on android know create bunch of items on canvas overriding ondraw(). however, let's suppose visualization bigger screen allows. for example in first picture below large black box contains entire canvas render it. create blue line runs vertically , down several yellow, green , blue rectangles. red box represents screen of android rendering visualization. opens items drawn items contained within red box show on screen. now if user scroll down, items appeared below red box in view while items have gone out of confines of red box no longer visable, represented in second picture. i believe need use scrollables i'm quite lost how so. i've read on page http://developer.android.com/training/custom-views/custom-drawing.html explaining how c

i'm implementing simple file sending method based on example found here , i'm having trouble finding reference on how go sending filename and/or type before sending actual bytes. examples i've seen, manually set filename on receiving end. my thought far sending separately string, curious if i'm missing easier/convenient way of doing this. so, there method within tcpclient/tcplistener send filename i've missed? there common way of doing haven't run across? if necessary can post code well. all can send "data", flat array of bytes. need use kind of protocol both sender , listener apply data. you want transfer "two blocks of data", in case could: send size of each block, followed actual data, followed next block size , data, or: use separator character (which works if actual data not contain separator (and there solutions escaping separator in data)) alternatively format data, instance sending xml document, containing:

how can make vb6 compiler fail when forget declare variable? this stop various typing errors (both keyboard , data types) , errors this when tries access unexpected. problems caused not correctly declaring variables: unexplained errors when using undefined variable, in fact pointing somehting else variables having different values @ different times, due spelling mistakes trying access variables outside of scope appearing uninitialised you should use option explicit . should put on first line of every module , form's code section. you can configure vb6 ide add automatically new modules going tools > options > require variable declaration.

i pass poco properties stored procedure (update , add object) earlier versions of enterprise library (e.g. v2.0) can this: var arrparam = sqlhelperparametercache.getspparameterset(connectionstring(), sprocnameset); (int x = 0; x <= arrparam.length - 1; x++) { system.reflection.propertyinfo pi = dataobject.gettype() .getproperty(arrparam[x].parametername .substring(1, convert.toint32(arrparam[x].parametername.length) - 1)); arrparam[x].value = pi.getvalue(mydataobject, null); } sqlhelper.executescalar(connectionstring(), commandtype.storedprocedure, sprocnameset, arrparam); but version 5.0 (maybe earlier?) sqlhelperparametercache.getspparameterset method gone. the question is: how can stored-proc-parameters , fill these poco-properties-values? you can this: database db = databasefactory.createdatabase(); string spname = "mysp"; var parameters = new object[] { &q

when try test app on device, error message: could not launch "appname" 'a' packet returned error: -1 it sounds low level problem. have replaced cable, makes no difference. when have restarted xcode, app runs on device without problems. after test runs, however, error message reappears. any ideas causes error message? any ideas how can prevent error message appears?

we using vc ++ dll in vb 6.0 application. working in current server. plan deploy application in new server. now when tried execute vb6.0 application throwing abnormal erro , closes vb 6.0 application. i tried install vc++ redistributable package 2005 & higher.. not working.. please giude me pick correct version of redistributable package vb 6.0 thanks, gunasekaran sambandhan 1) use dependancy walker(depends.exe). application show dependancies needed vc++ dll. 2) show list of dlls. copy dlls directory vc++ dll exists. 3) if s vc++ mfc dll built "shared dll" option might need mfc dlls copied. 4) check correct c runtime library file msvcrt*.dll. file might required. although depends show these dependancies. 5) depends show whether there dependancy of c runtime library.

i using pcapdot.net dlls, both 32 , 64 bit. possible create 1 project 32 , 64 dlls after compiling create 2 different exe files 32 , 64 bit? your problem, probabbly (it's not clear) you're linking dll in project , pick right dll (32 or 64 bit) relative build of project. the solution referebce in project dll common name: say pcapdot.net dll , both platforms. and in post build event of project, based on current configuration of build, copy platform specific pcapdot.net dll folder project loads references. so when app loads load "correct" version of pcapdot.net dll . to more clear: say reference in project pcapdot.net dll "debug\external" in project tree have "your_project_name\dlls\x86\pcapdot.net dll" and "your_project_name\dlls\x64\pcapdot.net dll" say setuped project fro 64 bit compilation. in post build event, check , go copy "your_project_name\dlls\x64\pcapdot.net dll&quo

(this questions related this one , have moved grunt-ember-templates instead of grunt-contrib-handlebars ) i trying split ember.js handlebars templates in several files, in order make code base more manageable. using grunt-ember-templates , configured follows: ember_templates: { compile: { options: { templatename: function(sourcefile) { return sourcefile.replace(/app\/templates\//, ''); // <%= yeoman.dist %>/scripts/ } }, files: { '<%= yeoman.dist %>/scripts/templates.js': [ '<%= yeoman.app %>/templates/**/*.hbs' ] } } } this creates dist/scripts/templates.js expected, client happily loading. templates.js looks this: ember.templates["accounts"] = ember.handlebars.template(function anonymous(handlebars,depth0,helpers,partials,data) { ... this looks fine me: templates saved in ember.templates array
