i'm looking simple, concise explanation of difference between these two. msdn doesn't go hell of lot of detail here. __declspec(dllexport) tells linker want object made available other dll's import. used when creating dll others can link to. __declspec(dllimport) imports implementation dll application can use it. i'm novice c/c++ developer, perhaps someone's got better explanation i.

as example take following code: public enum exampleenum { foobar, barfoo } public class exampleclass : inotifypropertychanged { private exampleenum example; public exampleenum exampleproperty { { return example; } { /* set , notify */; } } } i want databind property exampleproperty combobox, shows options "foobar" , "barfoo" , works in mode twoway. optimally want combobox definition this: <combobox itemssource="what goes here?" selecteditem="{binding path=exampleproperty}" /> currently have handlers combobox.selectionchanged , exampleclass.propertychanged events installed in window binding manually. is there better or kind of canonical way? use converters , how populate combobox right values? don't want started i18n right now. edit so 1 question answered: how populate combobox right values. retrieve enum values list of strings via objectdataprovider static enum.getvalues method: <window.resources...

we storing plain text passwords web app have. i keep advocating moving password hash developer said less secure -- more passwords match hash , dictionary/hash attack faster. is there truth argument? absolutely none. doesn't matter. i've posted similar response before: it's unfortunate, people, programmers, emotional swayed argument. once he's invested in position (and, if you're posting here, is) you're not convince him facts alone. need switch burden of proof. need him out looking data hopes convince you, , in doing learn truth. unfortunately, has benefit of status quo, you've got tough road there.

after rendering full grid need change data context of selected row since "simple" objects filled data source , when single item selected (looking @ rowdetailsvisibilitychanged event), want change datacontext complex object, shows more info in details in collapsed row. using gridviewrowdetailseventargs.detailselement.datacontext seems trick details element expanded below row on selecting, header (columns) stay same , values not updated when changing gridviewrowdetailseventargs.detailselement.datacontext or gridviewrowdetailseventargs.row.datacontext . (imagine column of collapsed row bound name, name "john", , when expanding, row.datacontext changed to object property name "john dough", column still shows "john"). ok found solution , seems pretty simple. so ... hook event handler radgridview.rowdetailsvisibilitychanged , in event handler change item property of provided row: private void onrowdetailsvisibilitychanged(object se...

i've installed binary distribution of paraview on osx. when running can access python interpreter tools -> python shell. cannot figure out libraries need add pythonpath in order access vtk , paraview functionality directly python. of course compile source distribution myself, take lot of time. ideas? i basing answer on built paraview 3.9.0 cvs. should able access paraview directly regular python if add: <paraview-bld-directory>/utilities/vtkpythonwrapping/site-packages <paraview-bld-directory>/bin to pythonpath variable. did same approach fail work when tried binary distribution? sorry, wasn't sure how interpret comment working if build hand.

i know can use perror() in c print errors. wondering if there c++ alternative this, or whether have include (and therefore stdio.h) in program. trying avoid many c functions possible. thanks! you like: std::cerr << strerror(errno) << std::endl; that still ends calling strerror , you're substituting 1 c function another. otoh, let write via streams, instead of mixing c , c++ output, thing. @ least afaik, c++ doesn't add library act substitute strerror (other generating std::string , i'm not sure change strerror anyway).

so, i've been making ios apps since first ipod touch came out, has flabbergasted me; why list of new cocoa touch classes restricted subclasses of nsobject, uiview, , uitableview? routinely make subclasses of uiimageview , uiviewcontroller. am "doing wrong™?" have totally misunderstood mvc point make controller classes shouldn't? philosophical reasoning requiring classes never descend basic controller class? like @themikeswan says, there aren't gui templates when create new class in xcode gui. can create new subclass parent nsobject. after that, go code , change parent class whatever like. so... no, not doing wrong in sense rightly understand want subclass uiviewcontroller; yes, doing wrong since assume shouldn't because xcode gui not support :)

when programming contract function or method first checks whether preconditions fulfilled, before starting work on responsibilities, right? 2 prominent ways these checks assert , exception . assert fails in debug mode. make sure crucial (unit) test separate contract preconditions see whether fail. exception fails in debug , release mode. has benefit tested debug behavior identical release behavior, incurs runtime performance penalty. which 1 think preferable? see releated question here disabling assert in release builds saying "i never have issues whatsoever in release build", not case. assert shouldn't disabled in release build. don't want release build crashing whenever errors occur either, you? so use exceptions , use them well. use good, solid exception hierarchy , ensure catch , can put hook on exception throwing in debugger catch it, , in release mode can compensate error rather straight-up crash. it's safer way go.

consider following interface in java: public interface { public final string key = "a"; } and following class: public class implements { public string key = "b"; public string getkey() { return key; } } why possible class come along , override interface i's final constant? try yourself: a = new a(); string s = a.getkey(); // returns "b"!!! despite fact shadowing variable it's quite interesting know can change final fields in java can read here : java 5 - "final" not final anymore narve saetre machina networks in norway sent me note yesterday, mentioning pity change handle final array. misunderstood him, , started patiently explaining not make array constant, , there no way of protecting contents of array. "no", said he, "we can change final handle using reflection." i tried narve's sample code, , unbelievably, java 5 allowed me modify fi...

we implementing numerous services in our company , running versioning issues data contracts. 1 of problems have our data contract used model of actual application behind service. wondering approach others have taken in kind of situation or service versioning in general. aware of microsoft best practices guide wanted see if has other ideas on how version. the first rule of services, business object != message object. basicly, never expose business objects data contracts. or say, can't fax cat. can send facsimile of cat, can't send cat on wire. here's great picture remind you: http://www.humorhound.com/2009/04/demotivational-poster-youre-doing-it-wrong/ in more modern terms, mvvm pattern. view of model domain layer uses not built client, have create separate model , view other layers. yes seems lot more work, in end easier , better way build service oriented applications. versioning 1 of ways makes life easier. other important thing tend build models g...

i'm trying select 2 distinct numbers id1 , id2 following table: tb_table1( bigint id1 bigint id2 bigint userid) if select distinct id1, id2 tb_table1 i'll get, example, 2 rows, (111, 222) , (222,111). i want 1 of rows since don't care column, id1, or id2 result gets returned in. basically, want distinct pairs order doesn't matter. thoughts? in advance. it remiss of me not point out suggests table not quite normalized should - when users acquire third id? anyway. using fact union (as opposed union all ) automatically de-duplicate, do select id1, id2 tb_table1 id1 < id2 union select id2, id1 tb_table1 not id1 < id2

i .net guy , try understand concept behind rails , active record stuff. as can see in examples assume view 1:1 copy of model. in reality that´s not true. like view holds customer and contact person(s) not related customer. user should able edit both (customer , contact person(s) in 1 view e.g.) in every example see bind view directly 1 activerecord object. stuff model, validation , on bind 1 object mapped directly database. could rails guy explain what´s elegant way work active record in real life applications in complex model situations? in first moment thinking dtos not imagine way go rails. agree john.... you asked: "like view holds customer , contact person(s) not related customer. user should able edit both (customer , contact person(s) in 1 view e.g.)" ok, customer model has employees, right? if not, replace "employee" "person" /app/model/customer.rb class customer < activerecord::base has_many :employees accepts...

i realize it's possible define static class method private , protected in php. allows instantiated class, or public static method access it's own private/protected static methods. protected static function jumpover () however i'm not sure if legal in sense of oop design. can't find real info stating it's ok this. i'm worried php may "patch" in future versions if not valid , break scripts. thanks help. it is. static methods nothing more helper methods have code possibly don't want public. the other common object-oriented languages can think of have (c++, java, c#). don't think they're ever going remove feature. besides, guys @ php slow @ breaking existing features, wouldn't worry it.

ok, here's deal -- i'm running windows forms webbrowser control service. know thats no-no, seems work alright. the thing i'm running problem trying wait browser's pages load. in normal application, i'd like while (browser.readystate != complete) application.doevents() obviously won't work service. i've tried alternative: public class webcrawler { private class exposedactivexwebbrowser : system.windows.forms.webbrowser { public shdocvw.webbrowser underlyingwebbrowser { { return activexinstance shdocvw.webbrowser; } } } exposedactivexwebbrowser worker; public webbrowserreadystate readystate { { return worker.readystate; } } public htmldocument document { { return worker.document; } } public webcrawler() { worker = new exposedactivexwebbrowse...

i trying sort list using delegates getting signature match error. compiler says cannot convert 'anonymous method' list<mytype> mylist = getmylist(); mylist.sort( delegate (mytype t1, mytype t2) { return (t1.id < t2.id); } ); what missing? here references found , same way. developer fusion reference microsoft reference i think want: mylist.sort( delegate (mytype t1, mytype t2) { return (t1.id.compareto(t2.id)); } ); to sort need other "true/false", need know if equal to, greater than, or less than.

when browse code in vim, need see opening , closing parenthesis/ brackets, , pressing % seems unproductive. i tried :set showmatch , makes cursor jump , forth when type in bracket. if browsing written code? domatchparen in .vimrc file or :domatchparen within vim itself. edit: comes pi_paren plugin (which standard plugin).

i have ms sql server database growing number of stored procedures , user defined functions , see need organize code better. idea split sps , functions on several schemata. default schema hold the sps called outside. api of database in other words. second schema hold internal code, should not called outside. same tables: contain "raw" data, hold precalculated data optimizations, ... as have never used schema, have several questions: does make sense @ all? are there implications i'm not aware of? example performance issues when sp in schema using table in schema x? is possible restrict "outer world" use sps in schema? example: user allowed call objects in schema a, sps in schema still allowed use tables in schema b? as question subjective, have marked "community wiki". hope ok. yes, makes sense no difference in performance if schemas have same owner (ownership chaining) yes, permission schemas explicitly per client or have check...

i publishing code behind .aspx in sharepoint. can automatically publish .dll bin folder of virtual directory, cannot figure out how push .aspx pages , images server without manually using sharepoint designer. where folder exist? or need create sharepoint feature this? the .aspx files under c:\program files\common files\microsoft shared\web server extensions\12\templates\layouts a quick , dirty way deploy new functionality (which accessible on server) drop aspx's folder. not safe, gives way test things before investing time full blown solution/feature deployment. i suggest reading on andrew connell's development methods, think has book doing sharepoint development out too. 'developing sharepoint features' talk best jumpstart doing sharepoint development i've heard. http://www.andrewconnell.com/blog/

in opengl es 1.1, can use glrotatef() rotate model, function doesn't exist in opengl es 2.0. therefore, how perform rotation in opengl es 2.0? to follow on christian's said, you'll need keep track of model view matrix , manipulate perform rotations need. you'll pass in matrix uniform shader, , following: attribute vec4 position; uniform mat4 modelviewprojmatrix; void main() { gl_position = modelviewprojmatrix * position; } i've found core animation catransform3d helper functions work performing right kind of matrix manipulations needed this. can rotate, scale, , translate catransform3d, read out 4x4 matrix elements create model view matrix need. if want see in action, this sample iphone application created shows how perform rotation of cube using both opengl es 1.1 , 2.0.
