• "Find nearest location" by Zip/Postal Code?

  - by codemonkey613

  I need a "find nearest location" on our website. Where visitor enters their zip/postal code, then they are redirected to specific webpage for our nearest location. We have forty USA and Canada locations. How can I build something like this? Could I do this with the Google Maps API? I already have a custom map on Google Maps. It's plotted with our locations. It would be nice to send Google Maps a command to say "what's our nearest location at __ zip code". Any suggestions?

• Teaching coworkers LINQ...

  - by cyberzed

  I have set myself upon a journey to educate my coworkers (all have accepted my mission, even the boss). Every day I seem to find a piece of code that could have been less error prone if my coworkers knew more about the framework, better-know-framework (in courtesy of DNR ;)) is part two of my teaching process. First part is teaching my coworkers about LINQ, what it can do for them and how it is written. My big question is where are all the good basic resources for LINQ education, everything if find is tightly coupled to Linq2Sql or all other sorts of material. Neither have I been able to find a tutorial for the actual linq syntax (except a specification of it all). (I hope this haven't been asked before but if it has please say so, cause then my searching skills have failed ;) )

• The Project Location is Not Trusted error in Visual Studio

  - by SLC

  Quite a simple error, and the reason is obvious - I mapped a network drive, and I am opening the solution from it. Visual Studio gives me this error. I tried googling, and to my surprise, couldn't find a fix. I am running Visual Studio 2008. The solutions I found on google say I should run Mscorcfg.msc, but unfortunately, I don't seem to have that file anywhere on my computer. Nor do I seem to have anything in my control panel relating to .NET Framework. I can of course, run .NET applications fine, so the framework exists. Another solution suggested running caspol.exe, although this is .NET 2, which I also tried to no avail. Any ideas? I should add that I am trying to add the path to whatever trusted list there is.

• Entity Framework and the XmlIgnoreAttribute

  - by Mikey Cee

  Say you have a one to one relationship in your entity model. The code generator will decorate it with the following attributes: [global::System.Xml.Serialization.XmlIgnoreAttribute()] [global::System.Xml.Serialization.SoapIgnoreAttribute()] public RelatedObject Relationship { get {...} set {...} } I want to serialize my parent object together with all its properties for which data has been loaded through an XML web service. Obviously, these related properties do not get serialized because of these attributes. So for my purposes I just want to remove these "don't serialize me" attributes. I can do a find and replace in the designer code, but any modifications I make in the designer will put these attributes back in. How do I permanently get rid of these attributes? VS 2008 / EF 3.5.

• how to convert byte array to key format??

  - by sebby_zml

  hi everyone, i would like to know how to convert byte array into key. i am doing an AES encryption/decryption. instead of generating a key, i would like to use my generated byte array. byte[] clientCK = Milenage.f3(sharedSecret16, RANDbytes, opc); let say i have a byte array called clientCK, stated above. i want to use it in AES encryption as shown below. Cipher c = Cipher.getInstance("AES"); c.init(Cipher.ENCRYPT_MODE, key); byte[] encValue = c.doFinal(valueToEnc.getBytes()); String encryptedValue = new BASE64Encoder().encode(encValue); therefore, i need to convert that byte array clientCK into key format. please help.

• How does MTOM work + sample code

  - by zengr

  I am trying to make a very simple web-service which does the following: The client hits the web service requesting a file. The web service's service class queries a hashtable which has the key (search query) and the value as the base64encoded value of a file (say a pdf) Now,I need to use MTOM to return the base64encoded value stored in the hashtable to the client. It's upto the client to decode it and convert it to pdf. So, here are my questions: I understand we encode files to base64 for transmission via web service, but where and how does MTOM come into the picture there? Can some one provide me a simple method which uses MTOM and sends the data back. Do we need to specify something in the WSDL too? or a simple String return type would suffice? Why/Why not? Thanks I have seen this code. It uses a lot of annotations, I just need a simple java code using MTOM. New to J2EE HERE :)

• git pull currently tracked branch

  - by Sean Clark Hess

  I use git checkout -b somebranch origin/somebranch to make sure my local branches track remotes already. I would like a way to pull from the tracked branch no matter which branch I am using. In other words, I want to say git pull or some other command, without specifying the branch, and have it mean git pull origin somebranch if I'm on the local branch somebranch Is there a way to do this without putting an entry in the config file for each branch? It would be difficult to maintain if we have to remember to manually enter some config stuff for each branch.

• Overriding classes/functions from a .dll.

  - by Jeff

  Say I have class A and class B. B inherits from class A, and implements a few virtual functions. The only problem is that B is defined in a .dll. Right now, I have a function that returns an instance of class A, but it retrieves that from a static function in the .dll that returns an instance of class B. My plan is to call the created object, and hopefully, have the functions in the .dll executed instead of the functions defined in class A. For some reason, I keep getting restricted memory access errors. Is there something I don't understand that will keep this plan from working?

• What is a good pattern for binding a collection of objects coming from WCF, in Silverlight?

  - by Krishna

  Hi there, I've got a question about a Silverlight WCF Databinding pattern: There are many examples about how to bind data using {Binding} expressions in XAML, how to make async calls to a WCF service, set the DataContext property of a element in the UI, how to use ObservableCollections and INotifyPropertyChanged, INotifyCollectionChanged and so on. Background: I'm using the MVVM pattern, and have a Silverlight ItemsControl, whose ItemsSource is set to an ObservableCollection property on my ViewModel object. My view is of course the XAML which has the {Binding}. Say the model object is called 'Metric'. My ViewModel periodically makes calls to a WCF service that returns ObservableCollection. MetricInfo is the data transfer object (DTO). My question is two-fold: Is there any way to avoid copying each property of MetricInfo to the model class - Metric? When the WCF calls completes, is there any way to make sure I sync the items which are in both my local ObservableCollection and the result of the WCF call - without having to first clear out all the items in the local collection and then add all the ones from the WCF call result? thanks, Krishna

• XML::LibXML: How to write a xpath with qualified name?

  - by sid_com

  I've found this on http://www.perlmonks.org/?node_id=606909 looking by qualified name ... In this case you can call findnodes method on any node, you don't need the XML::LibXML::XPathContext with its prefix = namespace mapping: $doc-findnodes('///info/fooTransaction/transactionDetail/[name() = "histFile:transactionSummary"]/*'); In which way I have to edit my xpath to get my script working without XPathContext? #!/usr/bin/env perl use warnings; use strict; use 5.012; use XML::LibXML; my $parser = XML::LibXML->new; $parser->recover_silently( 1 ); my $doc = $parser->parse_file( 'http://www.heise.de/' ); my $xc = XML::LibXML::XPathContext->new( $doc->getDocumentElement ); $xc->registerNs( 'xmlns', 'http://www.w3.org/1999/xhtml' ); my $nodes = $xc->findnodes( '//xmlns:h2/xmlns:a' ); for my $node ( $nodes->get_nodelist ) { say $_->getName, '=', $_->getValue for $node->attributes; }

• Is there a Perl module or technique that makes using long namespaces easier?

  - by Robert P

  Some namespaces are long and annoying. Lets say that i downloaded hypothetical package called FooFoo-BarBar-BazBaz.tar.gz, and it has the following modules: FooFoo::BarBar::BazBaz::Bill FooFoo::BarBar::BazBaz::Bob FooFoo::BarBar::BazBaz::Ben FooFoo::BarBar::BazBaz::Bozo FooFoo::BarBar::BazBaz::Brown FooFoo::BarBar::BazBaz::Berkly FooFoo::BarBar::BazBaz::Berkly::First FooFoo::BarBar::BazBaz::Berkly::Second Is there a module or technique I can use that's similar to the C++ 'using' statement, i.e., is there a way I can do using FooFoo::BarBar::BazBaz; which would then let me do my $obj = Brown->new(); ok $obj->isa('FooFoo::BarBar::BazBaz::Brown') ; # true # or... ok $obj->isa('Brown'); # also true

• WPF, animate over container boundaries

  - by ImIan

  Hi, I'm learning WPF and have a specific goal. Imagine you have a grid (3 rows by 3 columns), and a control, say a simple blue rectangle fills the middle cell. When I click on the cell I want the square to rotate smoothly through 180 degrees. The specific issue I have at the moment is; as the rectangle rotates, it won't change its dimensions, so it will extend beyond the boundary of the cell. I don't want it to clip, i want it to appear on top, partially obscuring surrounding cells. The second part of this is, if there is one cell that fills the entire window, and I click on the blue rectangle in that cell, can I make the rectangle rotate and extend beyond the sides of the form? If that doesn't make sense, please ask. I'm finding it hard to google because I don't know the exact terms I should be using. Thank you

• Artistic aspects of UI?

  - by anon

  Consider a single button. At one extreme, we have a black OpenGL window, with: outline (in white) of a rectangle bitmap remdered font inside of it, saying "Ok" At the other extreme, we have Mac OS X, a button that is: well rounded has some gradient showing light effects on it nice antialiased "OK" soft shadow of some sort These two UIs present very very different user experiences. The former says "This is from the 80s" the latter says "this is professional". This is something I do not understand well as a programmer (and don't know where to learn about this). Does anyone know of a good technical resource for this? [I'd prefer things that draws upon psychology / perception literature to say why to do something rather than design books that just says "use color XYZ with a gradient of blah"]

  Hi What was that "wpf trigger events after a few Milli-seconds" ;) Let me explain about that: I have a wpf form with few controls. some of these control over-writing template. for example a textblock with an effect will be trigger on Mouse-Enter event and change color of foreground to something else. But after running program when mouse enter on textBloc, it takes a few Milli-seconds until Mouse-enter event triggers. also all control or better say all control which use mouse-events have this problem.

• Unique Key in MySql

  - by Vinodtiru

  I have a table with four Columns. Col1, Col2, Col3, and Col4. Col1, Col2, Col3 is string and Col4 is a integer primary key with Auto Increment. Now my requirement is to have unique combination of Col2 and Col3. I mean to say like. Insert into table(Col1,Col2,Col3) Values('val1','val2','val3'); Insert into table(Col1,Col2,Col3) Values('val4','val2','val3'); the second statement has to throw error as the same combination of 'val2','val3' is present in the table. But i cant make it as a primary key as i need a auto increment column and for that matter the col4 has to be primary. Please let me know a approach by which i can have both in my table. Any kind of help is appreciated. Thanks.

• enable profiler / Traceon after SQL server restart automatically

  - by Nikhil

  hi, My client is facing some deadlocks while using our application. I want to track all the deadlocks for my research and to solve the deadlocks. i am currently run the SQL profiler for the event deadlock graph to capture the deadlock scenario. the actual problem is that the SQL server gets restarted every day at 2 am, and the profiler stops capturing the events after the restart. by the time i come to office at start the profiler at say 10 am, there could be deadlocks which i could have missed between 2 am and 10 am. so i am looking for a way so i can capture the deadlocks without me starting manually. i thought i could use TRACEON(1204,-1) so that the deadlock events get captured in the SQL Server error logs. But i found that the TRACE capturing too gets disabled after the restart. Is there a way i can capture the deadlocks either by SQL profiler or by using TRACEON without me manually starting the capturing? Nikhil

• How do I prevent jagged edges alongside the surfaces of my 3d model?

  - by badcodenotreat

  Lets say I've implemented in openGL a crude model viewer with shading which renders a series of blocks, such that I have something that looks like this. http://i.imgur.com/TsF7K.jpg Whenever I rotate my model to the side, it causes an unwanted jagged effect along any surface with a steep viewing angle. http://i.imgur.com/Bgl9o.jpg I'm pretty sure this is due to the polygon offset I used to prevent z-fighting between the model and the wireframe, however I'm not able to find the factor/unit parameters in openGL which prevent this unwanted effect. what are the best values of factor and unit for glPolygonOffset to prevent this? would implementing anti-aliasing alleviate the problem? is the trade off in performance trivial/significant? is this perhaps a shading issue? should i try a solution along this line of thought?

• Defining a SPI in Clojure

  - by Joe Holloway

  I'm looking for an idiomatic way(s) to define an interface in Clojure that can be implemented by an external "service provider". My application would locate and instantiate the service provider module at runtime and delegate certain responsibilities to it. Let's say, for example, that I'm implementing a RPC mechanism and I want to allow a custom middleware to be injected at configuration time. This middleware could pre-process the message, discard messages, wrap the message handler with logging, etc. I know several ways to do this if I fall back to Java reflection, but feel that implementing it in Clojure would help my understanding. (Note, I'm using SPI in a general sense here, not specifically referring to the way it's defined in the JAR file specification) Thanks

• Javas Math.sin() produces NaN all the time

  - by milan1612

  Forgive me if this is a dumb beginners problem, but I really don't get it. I have a member variable declared like so: public Double Value; When I assign 3.14159265 to Value and try to compute the sine of it, this happens: system.out.println(Value.toString()); //outputs 3.14159265 Value = Math.sin(Value); system.out.println(Value.toString()); //outputs NaN In fact, this happens with every single value I tried - even with 0! Math.sin() seems to always produce NaN as a result, regardless of the arguments value. The docs say: If the argument is NaN or an infinity, then the result is NaN. But my argument is clearly not NaN or infinity! What the heck is happening there?

• How do you unit test web page authorization using ASP.NET MVC?

  - by Kevin Pang

  Let's say you have a profile page that can only be accessed by the owner of that profile. This profile page is located at: User/Profile/{userID} Now, I imagine in order to prevent access to this page by other users, you could structure your UserController class's Profile function to check the current session's identity: HttpContext.Current.User.Identity.Name If the id matches the one in the url, then you proceed. Otherwise you redirect to some sort of error page. My question is how do you unit test something like this? I'm guessing that you need to use some sort of dependency injection instead of the HttpContext in the controller to do the check on, but I am unclear what the best way to do that is. Any advice would be helpful.

• Normalization in plain English

  - by Yada

  I sort of understand the concept of database normalization but always have a hard time explaining it in plain English especially for a job interview. I have read the wikipedia post, but still find it hard to explain the concept to none developers. "Design a database in a way not to get duplicated data" is the first thing that comes to mind. Does anyone was a nice way to explain the concept of database normalization in plain English. And what are some nice examples to show the differences between first, second and third normal forms. Say you go to a job interview and the person asks: Explain the concept of normalization and how would go about designing a normalized database. What key points are the interviewer looking for?
