• Where can I find free WPF controls and control templates?

  - by Geoffrey Chetwood

  Duplicate: Where can I find free WPF controls and control templates? I am looking for some recommendations on good places to find libraries of controls/templates/styles for WPF. I know about the usual places like Infragistics, but it seems to me that there should be some kind of community effort by now to share nice, clean, well written controls for WPF controls. I am not big on the design side, and it would be nice to fill out my personal libraries with some nice examples from people who are better at design. Any ideas/recommendations?

• Interview questions for junior C and C++ developer position

  - by Ondrej Slinták

  What interview questions should people expect as a junior C and C++ developer? Code questions or more of theory? Solutions in pseudo-code or in C code? Maybe I'm misinterpreting the word "junior", but I have no idea what would anyone ask me if I have no C work experiences. I'm bit afraid of tricky questions with pointers, so I'd like to be sure what should I look up before actually going there. I'm a junior PHP developer with 1 year of experiences, if it helps the question. Hope it isn't duplicate as I'm asking particularly about junior developer job.

• MYSQL Fast Insert dependent on flag from a seperate table

  - by Stuart P

  Hi all. For work I'm dealing with a large database (160 million + rows a year, 10 years of data) and have a quandary; A large percentage of the data we upload is null data and I'd like to stop it from being uploaded. The data in question is spatial in nature, so I have one table like so: idLocations (Auto-increment int, PK) X (float) Y (foat) Alwaysignore (Bool) Which is used as a reference in a second table like so: idLocations (Int, PK, "FK") idDates (Int, PK, "FK") DATA1 (float) DATA2 (float) ... DATA7 (float) So, Ideally I'd like to find a method where I can do something like: INSERT INTO tblData(idLocations, idDates, DATA1, ..., DATA7) VALUES (...), ..., (...) WHERE VALUES(idLocations) NOT LIKE (SELECT FROM tblLocation WHERE alwaysignore=TRUE ON DUPLICATE KEY UPDATE DATA1=VALUES(DATA1) So, for my large batch of input data (250 values in a block), ignore the inserts where the idLocations matches an idLocations values flagged with alwaysignore. Anyone have any suggestions? Cheers. -Stuart Other details: Running MySQL on a semi-dedicated machine, MyISAM engine for the tables.

• International Assist on iPhone

  - by john-gosset

  Does anyone know if the International Assist feature on the iPhone works when dialing a number using the tel:// URL scheme from an application? For those unfamiliar, IA automatically prefixes the "+1" to US numbers when using the iPhone internationally. I know that this works when dialing from either the built-in Contacts or Phone apps, but can't find anything stating that it works when dialing numbers from an application. Also, is there any documentation as to whether this feature is included on Canadian (Rogers) or European iPhones (or is it only used by AT&T)? If IA does not work when dialing with a custom app, can someone point to the API that would allow me to detect that the use is roaming on a foreign network so I can essentially duplicate IA's functionality? Any help greatly appreciated!

• Static Member Variables of the Same Class in C++

  - by helixed

  I'm trying to create a class which contains a static pointer to an instance of itself. Here's an example: A.h: #include <iostream> #ifndef _A_H #define _A_H class A { static A * a; }; A * a = NULL; #endif However, when I include A.h in another file, such as: #include "A.h" class B { }; I get the following error: ld: duplicate symbol _a in /Users/helixed/Desktop/Example/build/Example.build/Debug/Example.build/Objects-normal/x86_64/B.o and /Users/helixed/Desktop/Example/build/Example.build/Debug/Examplebuild/Objects-normal/x86_64/A.o I'm using the Xcode default compiler on Mac OS X Snow Leopard. Thanks, helixed

• Is it good or bad practice to use var everywhere? [closed]

  - by Earlz

  Possible Duplicate: Use of var keyword in C# Hello, I've recently been discovering the awesomeness that is the var keyword in C#. Well, I didn't think about it before but I just wrote lines of code that are along the lines of var con=CreateNewConnection(); Where this would usually be IdbConnection con=CreateNewConnection(); Is this a good use of var? Is it possible to use var too often? Are there any downsides to using it? Also, one more point of consideration: We are not worried about backwards compatability. We just care that it runs on .NET 3.5

• Is there an easy way to get a list of all successful captures from a regex pre-5.10?

  - by Chas. Owens

  I know the right way to do this if I have Perl 5.10 is to use named captures and values %+, but in Perl 5.8.9 and how can I get a list of successful captures? I have come up with two methods that are both just terrible: #you need to list each possible match my @captures = grep { defined } ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11, $12, $13, $14, $15, $16); and #ew, I turned on symbolic references { no strict 'refs'; my @captures = map { defined $+[$_] ? $$_ : () } 1 .. $#+; } There is a third option I have found involving (?{}), but it requires global variables (because the closure happens at compile time) and takes the regex from reasonably clear to ungodly mess. The only alternative I have found is to capture the whole match and then use another set of regexes to get the values I want (actually I build the first regex out of the other regexes because there is no good reason to duplicate the logic).

• Do you have any tips for comments code to keep them in step with the code?

  - by Rob Wells

  G'day, I've read both of Steve McConnell's excellent Code Complete books "Code Complete" and "Code Complete 2" and was wondering if people have any other suggestions for commenting code. My commenting mantra could be summed up by the basic idea of expressing "what the code below cannot say". While enjoying this interesting blog post by Jeff about commenting I was still left wondering "When coding, when do you feel a comment is required?" Edit: Oops. Seems to be a duplicate of this question http://stackoverflow.com/questions/121945/how-do-you-like-your-comments so sorry for the noise. Thanks to my, seemingly, SO shadow for pointing it out - wouldn't have thought I was that interesting. Now off to read the original post and see if it is relevant. Edit: I meant to emphasise the best appraoch to ensure that your comments will stay in step with the code. Maybe expressing an intent rather than the mechansim for instance.

• view to select specific period or latest when null

  - by edosoft

  Hi I have a product table which simplifies to this: create table product(id int primary key identity, productid int, year int, quarter int, price money) and some sample data: insert into product select 11, 2010, 1, 1.11 insert into product select 11, 2010, 2, 2.11 insert into product select 11, 2010, 3, 3.11 insert into product select 12, 2010, 1, 1.12 insert into product select 12, 2010, 2, 2.12 insert into product select 13, 2010, 1, 1.13 Prices are can be changed each quarter, but not all products get a new price each quarter. Now I could duplicate the data each quarter, keeping the price the same, but I'd rather use a view. How can I create a view that can be used to return prices for (for example) quarter 2? I've written this to return the current (=latest) price: CREATE VIEW vwCurrentPrices AS SELECT * FROM ( SELECT *, ROW_NUMBER() OVER (PARTITION BY productid ORDER BY year DESC, quarter DESC) AS Ranking FROM product ) p WHERE p.Ranking = 1 I'd like to create a view so I can use queries like select * from vwProduct where quarter = 2

• how to link with static mySQL C library with Visual Studio 2008?

  - by Jean-Denis Muys

  Hi, My project is running fine, but its requirement for some DLLs means it cannot be simply dragged and dropped by the end user. The DLLs are not loaded when put side by side with my executable, because my executable is not an application, and its location is not in the few locations where Windows looks for DLL. I already asked a question about how to make their loading happen. None of the suggestions worked (see the question at http://stackoverflow.com/questions/2637499/how-can-a-win32-app-plugin-load-its-dll-in-its-own-directory) So I am now exploring another way: get rid of the DLLs altogether, and link with static versions of them. This is failing for the last of those DLLs. So I am at this point where all but one of the libraries are statically linked, and everything is fine. The last library is the standard C library for mySQL, aka Connector/C. The problem I have may or may not be related with that origin. Whenever I switched to the static library in the linker additional dependency, I get the following errors (log at the end): 1- about 40 duplicate symbols (e.g. _toupper) mutually between LIBCMT.lib and MSVCRT.lib. Interestingly, I can't control the inclusion of these two libraries: they are from Visual Studio and automatically included. So why are these symbol duplicate when I include mySQL's static lib, but not its DLL? Searching C:\Program Files\Microsoft Visual Studio 9.0\VC\lib\MSVCRT.lib: Searching C:\Program Files\Microsoft Visual Studio 9.0\VC\lib\OLDNAMES.lib: Searching C:\Program Files\Microsoft Visual Studio 9.0\VC\lib\msvcprt.lib: Searching C:\Program Files\Microsoft Visual Studio 9.0\VC\lib\LIBCMT.lib: LIBCMT.lib(setlocal.obj) : error LNK2005: _setlocale already defined in MSVCRT.lib(MSVCR90.dll) Searching C:\Program Files\Microsoft Visual Studio 9.0\VC\lib\MSVCRT.lib: MSVCRT.lib(MSVCR90.dll) : error LNK2005: _toupper already defined in LIBCMT.lib(toupper.obj) 2- two warnings that MSVCRT and LIBCMT conflicts with use of other libs, with a suggestion to use /NODEFAULTLIB:library:. I don't understand that suggestion: what am I supposed to do and how? LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library LINK : warning LNK4098: defaultlib 'LIBCMT' conflicts with use of other libs; use /NODEFAULTLIB:library 3- an external symbol is undefined: _main. So does that mean that the static mySQL lib (but not the DLL) references a _main symbol? For the sake of it, I tried to define an empty function named _main() in my code, with no difference. LIBCMT.lib(crt0.obj) : error LNK2001: unresolved external symbol _main As mentioned in my first question, my code is a port of a fully working Mac version of the code. Its a plugin for a host application that I don't control. The port currently works, albeit with installation issues due to that lone remaining DLL. As a Mac programmer I am rather disoriented with Visual Studio and Windows which I find confusing, poorly designed and documented, with error messages that are very difficult to grasp and act upon. So I will be very grateful for any help.

• iPhone: Having trouble figuring out how to scroll a UITableView with custom UITextField cells automa

  - by Gordon Fontenot

  Ok, I know this seems like a duplicate question, but don't think it is. I actually have this implemented already (thanks to this SO question), but it seems sluggish. I am willing to tweak it a bit, but I ran across a demo app by AboutObjects that seems to have exactly the right functionality with absolutely no code doing it. I have looked through their demo code dozens of times, and I can't figure out what they are doing that I am not. The code to look at is in their iPhone Development Tutorials section, and is called "Editable TableView" (2nd from the bottom). There are a couple of questions on the forums on that site asking how they got the functionality, but there is no answer (other than "It's a built in function"). Does anyone have any clue as to why their UITableView would implement the input scrolling by default (including being able to scroll the view manually when the keyboard pops up, which I cannot get to work)?

• ASP: Extend control (ASCX) and access base markup file from subclass code

  - by Pathoschild

  Hello, I'm building form validation controls for our C# ASP application. The bulk of the work is handled by a BaseValidator control (subclassing System.Web.UI.UserControl), which also has the markup for the validation output. This is then extended by subcontrols like PasswordValidator, that provides the Validate method and any extra fields needed by that validator control. (The end goal is to have controls like <uc1:PasswordValidator ControlId="txtPassword" /> which we can plop into any form with minimum duplication.) However, PasswordValidator.ascx.cs cannot access the form elements defined in BaseValidator.ascx; the only way I've found to do so is to duplicate the markup in each subcontrol's *.ascx file. How can I extend BaseValidator.ascx.cs and access BaseValidator.ascx's markup in the subclass?

• Get list of Unique many-to-many records from a queryset

  - by rsp

  My models: class Order(models.Model): ordered_by = models.ForeignKey(User) reasons = models.ManyToManyField(Reason) class Reason(models.Model): description = models.CharField() Basically a user creates an order and gives reasons for that order. ie, john has two orders (one for pencils because he is out AND because he doesn't like his current stock. a second order for pens because he is out). I want to print a list out of all reasons a user has placed his orders. So under john, it should print "he is out", "he doesn't like his current stock"; those two lines only. If I simply select all of john's orders, iterate through them and print out their "reasons" it'll print "he is out", "he doesn't like his current stock" and then "he is out" again. I don't want these duplicate values. How do I select a list of his reasons for ALL his orders so that the list has all unique rows?

• How to create a draggable overlayItem in Android 2.1

  - by Zap

  Does anyone know how to make a map overlayitem draggable so I can press and hold it and drag it across the map. I am trying to duplicate the draggable icon behavior that's available on the iPhone. One developer suggested a possible solution is to detect a touch event, get rid of the existing overlay item, draw your own copy of the icon where the overlay item had been, manually animate that as the user drags, and then put the overlay item where the user drops it (getting rid of your manually-drawn icon). Does anyone have sample java code to do this Android 2.1? This would be much appreciated.

• Is there a logging facade for the .NET world?

  - by Elijah

  I'm somewhat new to the .NET stack and I was wondering if there is an equivalent to slf4j for the .NET platform. For me, logging to a Facade and being able to swap out logging implementations as needed just makes sense. Furthermore, the wrapper APIs available in slf4j have saved me many times when I needed to use a third-party library that was coded against a single logging framework that I wasn't using. Is there a project out there that acts as a facade between loggers like log4net, nLog and Enterprise Library? Are there wrappers that allow me to shortcut calls to those libraries and direct them to another library? Should I start out an open source project to do this myself? Is this question a duplicate because I don't know the right way to ask? Conversely, is the common way to do this using aspect orient programming?

• setting source classpath in eclipse with stupid project structure

  - by lisak

  What do you guys do, when you have huge project built with ant for instance, where the source folders are right bellow the root project folder, for building classpath from source files ? putting entire project as a source folder is nonsense. Putting separate folders as source folders can't be done if they are part of the package hierarchy and the only thing I could think of, is to copy the source folders into a separate folder and add it then as source folder which is weird but I don't know how else to do it. Having to duplicate sources just because of the eclipse way of making classpath and also because of somebody doing stupid project structure

• How can I block based on URL (from address bar) in a safari extension

  - by PerilousApricot

  I'm trying to write an extension that will block access to (configurable) list of URLs if they are accessed more than N times per hour. From what I understand, I need to have a start script pass a "should I load this" message to a global HTML page (who can access the settings object to get the list of URLs), who will give a thumbs up/thumbs down message back to the start script to deny/allow loading. That works out fine for me, but when I use the usual beforeLoad/canLoad handlers, I get messages for all the sub-items that need to be loaded (images/etc..), which screws up the #accesses/hour limit I'm trying to make. Is there a way to synchronously pass messages back and forth between the two sandboxes so I can tell the global HTML page, "this is the URL in the window bar and the timestamp for when this request came in", so I can limit duplicate requests? Thanks!

• How can I run NUnit(Selenium Grid) tests in parallel?

  - by Benjamin Lee

  My current project uses NUnit for unit tests and to drive UATs written with Selenium. Developers normally run tests using ReSharper's test runner in VS.Net 2003 and our build box kicks them off via NAnt. We would like to run the UAT tests in parallel so that we can take advantage of Selenium Grid/RCs so that they will be able to run much faster. Does anyone have any thoughts on how this might be achieved? and/or best practices for testing Selenium tests against multiple browsers environments without writing duplicate tests automatically? Thank you.

• Sql Server - INSERT INTO SELECT to avoid duplicates

  - by Ashish Gupta

  I have following two tables:- Table1 ------------- ID Name 1 A 2 B 3 C Table2 -------- ID Name 1 Z I need to insert data from Table1 to Table2 and I can use following sytax for the same:- INSERT INTO Table2(Id, Name) SELECT Id, Name FROM Table1 However, In my case duplicate Ids might exist in Table2 (In my case Its Just "1") and I dont want to copy that again as that would throw an error. I can write something like this:- IF NOT EXISTS(SELECT 1 FROM Table2 WHERE Id=1) INSERT INTO Table2 (Id, name) SELECT Id, name FROM Table1 ELSE INSERT INTO Table2 (Id, name) SELECT Id, name FROM Table1 WHERE Table1.Id<>1 Is there a better way to do this without using IF - ELSE? I want to avoid two INSERT INTO-SELECT statements based on some condition. Any help is appreciated.

• Best way to handle multiple getView calls from inside an Adapter

  - by Samuh

  I have a ListView with custom ArrayAdapter. Each of the row in this ListView has an icon and some text. These icons are downloaded in background,cached and then using a callback, substituted in their respective ImageViews. The logic to get a thumbnail from cache or download is triggered every time getView() runs. Now, according to Romain Guy: "there is absolutely no guarantee on the order in which getView() will be called nor how many times." I have seen this happen, for a row of size two getView() was being called six times! How do I change my code to avoid duplicate thumbnail-fetch-requests and also handle view recycling? Thanks.

• Supporting different locale regions using Rails i18n

  - by Olly

  I'm using the standard Rails I18n API to localise some of our views. This is working really well, but we now have a few use cases for regional changes to the en locale. The API guide mentions that this isn't supported directly, and other plugins should be used. However, I'm wondering whether there's a simpler way to do this. I already have en.yml, so in theory I could just create en-AU.yml and en-US.yml which are effectively clones of en.yml but with a few regional changes applied. I could then add additional English - American and English - Australian options to our configuration which would map to the new region-specific locales and allow users to use a region-specific locale. The only problem I can think of with this is that it isn't DRY -- I would have duplicate translations for all common English words. I can't see a way around this. Are there any other disadvantages to this approach, or should I just bite the bullet and dive into one of the plug-ins such as Globalize2 instead?

  I work on a project where we have to create unit tests for all of our simple beans (POJOs). Is there any point to creating a unit test for POJOs if all they consist of is getters and setters? Is it a safe assumption to assume POJOs will work about 100% of the time? Duplicate of - Should @Entity Pojos be tested?

And after that I copied in in another file and it will not working. There is no duplicate ID or anything else in the document
