• drupal themes: how do I include several css files / js files on my theme's .info file?

  - by egarcia

  I'm creating a new Drupal theme. Until now, I only needed to include a single css file and a single js file. So my theme.info file had something like this: stylesheets[all][] = css/style.css scripts[] = js/script.js Now I must include jquery and jquery-ui in order to use a calendar date. These come with 2 new javascript files, and 1 additonal css file that I must add to the site. The calendar input form is going to be used in all pages (on a side block) so it is ok for me to load the extra css/javascript on all pages. I think the easiest thing would be to reference them on the .info file itself. At first I tried to just put them there with separate spaces: stylesheets[all][] = css/style.css css/ui-lightness/jquery-ui-1.8.1.custom.css scripts[] = js/script.js js/jquery-1.4.2.min.js js/jquery-ui-1.8.1.custom.min.js I emptied drupal's cache and... none of them loaded. I then tried separating each file with a comma, and flushing the cache again. Same result. I've browsed some drupal pages, but could not find how to add several javascript/css files on one theme (they always seem to add just 1 of each). So, how do I include several css/javascript files on the .info file?

• Silverlight Business Application template with WCF is throwing warning.

  - by Manoj

  Hi, I am using the Silvelight Business Application template. I wrote a function which uses Membership.getUserList function to return the user list. I tried exposing it as Service using WCF. But when I try to compile the client side code it throws a warning saying "Client Proxy Generation for user_authentication.Web.Service1 failed'. Why does it happen? The complete warning message is: Warning 4 Client proxy generation for service 'user_authentication.Web.Service1' failed: Generating metadata files... Warning: Unable to load a service with configName 'user_authentication.Web.Service1'. To export a service provide both the assembly containing the service type and an executable with configuration for this service. Details:Either none of the assemblies passed were executables with configuration files or none of the configuration files contained services with the config name 'user_authentication.Web.Service1'. Warning: No metadata files were generated. No service contracts were exported. To export a service, use the /serviceName option. To export data contracts, specify the /dataContractOnly option. This can sometimes occur in certain security contexts, such as when the assembly is loaded over a UNC network file share. If this is the case, try copying the assembly into a trusted environment and running it.

• iPhone development - app design patterns

  - by occulus

  There are tons of resources concerning coding on the iPhone. Most of them concern "how do I do X", e.g. "setup a navigation controller", or "download text from a URL". All good and fine. What I'm more interested in now are the questions that follow the simpler stuff - how to best structure your complex UI, or your app, or the common problems that arise. To illustrate: a book like "Beginning iPhone 3 Development" tells you how to set up a multi viewcontroller app with an top 'switcher' viewcontroller that switches between views owned by other view controllers. Fine, but you're only told how to do that, and nothing about the problems that can follow: for example, if I use their paradigm to switch to a UINavigationViewController, the Navigation bar ends up too low on the screen, because UINavigationViewController expects to be the topmost UIViewController (apparently). Also, delegate methods (e.g. relating to orientation changes) go to the top switcher view controller, not the actual controller responsible for the current view. I have fixes for these things but they feel like hacks which makes me unhappy and makes me feel like I'm missing something. One productive thing might be to look at some open source iPhone projects (see this question). But aside from that?

• VS2010 final does only link project on "rebuild all", not on "build changed"

  - by Sam

  I've just migrated a solution containing c++ and c# projects from VS2008 to VS2010 and got a strange problem. When I select "rebuild all", everything compiles and links as I would expect it to do. Then I change some c++ source file (just add a space), build the project, I get several thousands of linking errors like these: GDlgPackerListe.obj : error LNK2028: Nicht aufgelöstes Token (0A0000C7) ""public: bool __thiscall LList::Add(class LBString const &)" (?Add@LList@@$$FQAE_NABVLBString@@@Z)", auf das in Funktion ""public: virtual void __thiscall LRcPackerListe::HookRunReport(class LFortschritt &)" (?HookRunReport@LRcPackerListe@@$$FUAEXAAVLFortschritt@@@Z)" verwiesen wird.

When I hit "rebuild all" it recompiles and links without any errors or even warnings and produces a working exe. I'm using Visual Studio 2010 final (german edition). Whats going on here? Or, more important: how do I get the linker to work correctly??

• .Net in HTML tp return true if reader object not null, otherwise return false

  - by Phill Healey

  I'm using a DataList to show some data from the database and populating the fields on the html side. I now have a requirement to change the visibility of a panel based on whether or not a db field has data or not. I need to be able to show the panel if the relevant data field has content, and hide it if it doesn't. Eg: <asp:Panel ID="pnlNew" runat="server" Style="margin:0; padding:0; width:42px; height:18px; bottom:5px; right:10px; float:right; position:relative; background:url(../_imgVideoBadge.png) no-repeat;" Visible='<%# Eval("cheese") != null %>' ToolTip="available"></asp:Panel> Obviously this doesn't work in terms of the visible property. But hopefully it gives an idea of what I'm trying to achieve. Any help would be greatly appreciated. I've seen examples previously of doing something along the lines of: a ?? b:c How could this be applied to the above requirement?? Thanks in advance.

• How can I make one Maven module depend on another?

  - by Daniel Pryden

  OK, I thought I understood how to use Maven... I have a master project M which has sub-projects A, B, and C. C contains some common functionality (interfaces mainly) which is needed by A and B. I can run mvn compile jar:jar from the project root directory (the M directory) and get JAR files A.jar, B.jar, and C.jar. (The versions for all these artifacts are currently 2.0-SNAPSHOT.) The master pom.xml file in the M directory lists C under its <dependencyManagement> tag, so that A and B can reference C by just including a reference, like so: <dependency> <groupId>my.project</groupId> <artifactId>C</artifactId> </dependency> So far, so good. I can run mvn compile from the command line and everything works fine. But when I open the project in NetBeans, it complains with the problem: "Some dependency artifacts are not in the local repository", and it says the missing artifact is C. Likewise from the command line, if I change into the A or B directories and try to run mvn compile I get "Build Error: Failed to resolve artifact." I expect I could manually go to where my C.jar was built and run mvn install:install-file, but I'd rather find a solution that enables me to just work directly in NetBeans (and/or in Eclipse using m2eclipse). What am I doing wrong?

• What are Sharepoint(MOSS 2007) Developement/Deployment best practices.

  - by Satish

  We are deploying sharepoint MOSS 2007 at our work. I'm trying to come up with a sharepoint development and deployment methodology. We have Dev/QA/Prod environments and I need a way, preferably automated to deploy changes from Dev to QA and from there to prod. We are creating site collections web parts etc. Some of it is done directly within sharepoint, some through Sharepoint designer or visual studio. I'm looking for a way to extract this and deploy it to other enviornments. I tried stsadm backup/restore import/export etc but they all move the data along with it as well. I just need the structure deployed. Content deployment paths and jobs does the same thing as well. We use MSBuild & Curisecontrol.net for other .net projects to automate build/deployment process. I'm looking for something similar with sharepoint if possible. What are your best practices for this? Since my team is learning we don't have a defined process and we are open to change our development process if needed.

• Wrapper background image gets cut off at the top

  - by dq7133

  My site has a wrapper with three background images. A static top and bottom image and a third image that repeats along the y axis. For some reason the top background image is getting cut off and I can't figure out way. Here is a link to the live site: http://storrepictures.weebly.com/projects.html I have offset the top and bottom images so you can see what they look like. You can see that the top one is cut off. I've tried messing around with some of the div padding settings but can't seem to get it to work. One interesting note: The background images used to be JPEGs (I switched to PNG files because I needed transparency). When I was using JPEGs this was not a problem - the three images lined up perfectly. Let me know if it would help to have the actual code posted. From what I've been reading on this forum, people seem to like looking at the live site and I didn't want to make the post too long. Thanks a lot for all your help.

• Mapping relationships from multiple databases in NHibernate

  - by mannish

  I have a multi-database application configured with NHibernate. The entities that correspond to tables from each database are in their own separate assemblies (an assembly per database if you will). I have a need/desire to relate an entity from one database to an entity of another database. Everything up to this point works as I want it to (the application handles multiple session factories, etc.). The relationship I want is many-to-one, but in reality my application only cares about one side of the relationship (for reasons that aren't relevant). The relevant entities are Project and PMProject, where a Project HAS A PMProject. When I map the many-to-one, I get the following error: NHibernate.MappingException: An association from the table PROJECTS refers to an unmapped class: SDMS.PPRM.PMProject The Project mapping itself reads (ignore the funky column naming; it's an Oracle db): <many-to-one name="PMProject" class="SDMS.PPRM.PMProject" column="PM_PROJECT_ID" cascade="none" /> In the class attribute, I'm referencing the appropriate assembly, but I get that error which seems to tell me it simply can't find the mapping file for PMProject. But that file exists (it's set as embedded resource), the session factory instantiation works without fail; so I'm at a loss on how to tell the Project mapping how/where to look for the appropriate mapping. Is there something I'm missing? A better way to go about this? Thanks in advance.

• Mutually beneficial IP/copyright clauses for contract-based freelance work

  - by Nathan de Vries

  I have a copyright section in the contract I give to my clients stating that I retain copyright on any works produced during my work for them as an independent contractor. This is most definitely not intended to place arbitrary restrictions on my clients, but rather to maintain my ability to decide on how the software I create is licensed and distributed. Almost every project I work on results in at least one part of it being released as open source. Every project I work on makes use of third-party software released in the same fashion, so returning the favour is something I would like to continue doing. Unfortunately, the contract is not so clear when it comes to defining the rights of the client in the use of said software. I mention that the code will be licensed to them, but do not mention specifics about exclusivity, ability to produce derivatives etc. As such, a client has raised concerns about the copyright section of my contract, and has suggested that I reword it such that all copyrights are transferred entirely to the client on final payment for the project. This will almost certainly reduce my ability to distribute the software I have created; I would much prefer to find a more mutually beneficial agreement where both our concerns are appeased. Are there any tried and true approaches to licensing software in this kind of situation? To summarise: I want to maintain the ability to license (parts of) the software under my own terms, independently of my relationship with the client; with some guarantee to the client that no trade-secrets or critical business logic will be shared; giving them the ability to re-use my code in their future projects; but not necessarily letting them sell it (I'm not sure about this, though...what happens if they sell their business and the software along with it?) I realise that everyone's feedback is going to be prefixed with "IANAL", however I appreciate any thoughts you might have on the matter.

• Protecting my apps security from deassembling

  - by sandis

  So I recently tested deassembling one of my android apps, and to my horror I discovered that the code was quite readable. Even worse, all my variable names where intact! I thought that those would be compressed to something unreadable at compile time. The app is triggered to expire after a certain time. However, now it was trivial for me to find my function named checkIfExpired() and find the variable "expired". Is there any good way of making it harder for a potential hacker messing with my app? Before someone states the obvious: Yes, it is security through obscurity. But obviously this is my only option since the user always will have access to all my code. This is the same for all apps. The details of my deactivation-thingy is unimportant, the point is that I dont want deassembler to understand some of the things I do. side questions: Why are the variable names not compressed? Could it be the case that my program would run faster if I stopped using really long variable names, as are my habit?

• Storing an encrypted cookie with Rails

  - by J. Pablo Fernández

  I need to store a small piece of data (less than 10 characters) in a cookie in Rails and I need it to be secure. I don't want anybody being able to read that piece of data or injecting their own piece of data (as that would open up the app to many kinds of attacks). I think encrypting the contents of the cookie is the way to go (should I also sign it?). What is the best way to do it? Right now I'm doing this, which looks secure, but many things looked secure to people that knew much more than I about security and then it was discovered it wasn't really secure. I'm saving the secret in this way: encryptor = ActiveSupport::MessageEncryptor.new(Example::Application.config.secret_token) cookies[:secret] = { :value => encryptor.encrypt(secret), :domain => "example.com", :secure => !(Rails.env.test? || Rails.env.development?) } and then I'm reading it like this: encryptor = ActiveSupport::MessageEncryptor.new(Example::Application.config.secret_token) secret = encryptor.decrypt(cookies[:secret]) Is that secure? Any better ways of doing it? Update: I know about Rails' session and how it is secure, both by signing the cookie and by optionally storing the contents of the session server side and I do use the session for what it is for. But my question here is about storing a cookie, a piece of information I do not want in the session but I still need it to be secure.

• Rails: RESTful Find, Initialize, or Create

  - by Andrew

  I have an app that has Cities in it. I'm looking for some suggestions on how to RESTfully structure a controller so that I can lookup, initialize, and create city records via AJAX requests. For instance: Given a text field city_name A user enters the name of a City, like "Paris, France" The app checks this location to see if there is such a city in the database already If there is, it returns the city object If there is not, it returns a new record initialized with the name "Paris" and the country "France", and prompts the user to confirm they want to add this city to the database If the user says "Yes" the record is saved. If not the record is discarded and the form is cleared. Now, my first approach was to change the Create action to use find_or_create, so that an AJAX post to cities_path would result in either returning the existing city or creating it and returning it. That works ok... However, it would be better to setup controller actions that would take a string input, find , or else initialize and return, then only create if the user confirms the generated record is correct. The ideal scenario would put this all in one action so AJAX request can go to that url, the server responds with JSON objects, and javascript can handle things from there. I'd like to keep all the user-interaction logic client side, and also minimize the number of requests it takes to achieve this. Any suggestions on the cleanest, most RESTful way to accomplish this?

• TCP Message Structure with XML

  - by metdos

  Hello Everybody, I'm sending messages over TCP/IP and on the other side I parse TCP message.For example this is one of the sent messages. $DKMSG(requestType=REQUEST_LOGIN&requestId=123&username=metdos&password=123)$EDKMSG Clarification: $DKMSG( //Start )$EDKMSG //End requestType //Parameter REQUEST_LOGIN //Parameter Value Now I also want to add an Xml file to my message. I'm considering this option: $DKMSG(requestType=REQUEST_LOGIN&xmlData= <Item id="56D@MIT" type="SIGNAL"> <Label> <Text>56D</Text> <X1>10</X1> <Y1>40</Y1> <RotateAngle>90</RotateAngle> </Label> <X1>0</X1> <Y1>20</Y1> <Width>35</Width> <Height>10</Height> <Source>sgs3lr</Source> </Item> )$EDKMSG There are problems with this way: 1-)It doesn't seem right to me. 2-)I have to handle delimeter "=" with much more care or I need to change it in parameters. What are your suggestions, thanks.

• Statically checking a Java app for link errors

  - by monorailkitty

  I have a scenario where I have code written against version 1 of a library but I want to ship version 2 of the library instead. The code has shipped and is therefore not changeable. I'm concerned that it might try to access classes or members of the library that existed in v1 but have been removed in v2. I figured it would be possible to write a tool to do a simple check to see if the code will link against the newer version of the library. I appreciate that the code may still be very broken even if the code links. I am thinking about this from the other side - if the code won't link then I can be sure there is a problem. As far as I can see, I need to run through the bytecode checking for references, method calls and field accesses to library classes then use reflection to check whether the class/member exists. I have three-fold question: (1) Does such a tool exist already? (2) I have a niggling feeling it is much more complicated that I imagine and that I have missed something major - is that the case? (3) Do you know of a handy library that would allow me to inspect the bytecode such that I can find the method calls, references etc.? Thanks!

• Rebuilding old (2010) django project in 2012

  - by birgit

  I am trying to make an old Django project run again. After seemingly having solved issues with old sorl.thumbnail versions and deprecated expressions I now get this error when running python manage.py runserver I also tried to copy & paste my old files into a new Django project and get the exactly same error.

• Avoid slowdowns while using off-site database

  - by Anders Holmström

  The basic layout of my problem is this: Website (ASP.NET/C#) hosted at a dedicated hosting company (location 1) Company database (SQL Server) with records of relevant data (location 2). Location 1 & 2 connected through VPN. Customer visiting the website and wanting to pull data from the company database. No possibility of changing the server locations or layout (i.e. moving the website to an in-office server isn't possible). What I want to do is figure out the best way to handle the data acces in this case, minimizing the need for time-expensive database calls over the VPN. The first idea I'm getting is this: When a user enters the section of the website needing the DB data, you pull all the needed tables from the database into a in-memory dataset. All subsequent views/updates to the data is done on this dataset. When the user leaves (logout, session timeout, browser closed etc) the dataset gets sent to the SQL server. I'm not sure if this is a realistic solution, and it obviously has some problems. If two web visitors are performing updates on the same data, the one finishing up last will have their changes overwriting the first ones. There's also no way of knowing you have the latest data (i.e. if a customer pulls som info on their projects and we update this info while they are viewing them, they won't see these changes PLUS the above overwriting issue will arise). The other solution would be to somehow aggregate database calls and make sure they only happen when you need them, e.g. during data updates but not during data views. But then again the longer a pause between these refreshing DB calls, the bigger a chance that the data view is out of date as per the problem described above. Any input on the above or some fresh ideas would be most welcome.

• C#; On casting to the SAME class that came from another assembly

  - by G. Stoynev

  For complete separation/decoupling, I've implemented a DAL in an assebly that is simply being copied over via post-build event to the website BIN folder. The website then on Application Start loads that assembly via System.Reflection.Assembly.LoadFile. Again, using reflection, I construct a couple of instances from classes in that assembly. I then store a reference to these instances in the session (HttpContext.Current.Items) Later, when I try to get the object stored in the session, I am not able to cast them to their own types (was trying interfaces initially, but for debugging tried to cast to THEIR OWN TYPES), getting this error: [A]DAL_QSYSCamper.NHibernateSessionBuilder cannot be cast to [B] DAL_QSYSCamper.NHibernateSessionBuilder. Type A originates from 'DAL_QSYSCamper, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Users\dull.anomal\AppData\Local\Temp\Temporary ASP.NET Files\root\ad6e8bff\70fa2384\assembly\dl3\aaf7a5b0\84f01b09_b10acb01\DAL_QSYSCamper.DLL'. Type B originates from 'DAL_QSYSCamper, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'LoadNeither' at location 'C:\Users\dull.anomal\Documents\Projects\QSYS\Deleteme\UI\MVCClient\bin\DAL_QSYSCa mper.DLL'. This is happening while debugging in VS - VS manages to stop into the source DAL project even though I've loaded from assembly and the project is not refferenced by the website project (they're both in the solution). I do understand the error, but I don't understand how and why the assembly is being used/loaded from two locations - I only load it once from the file and there's no referrence to the project. Should mention that I also use Windsor for DI. The object that tries to extract the object from the session is A) from a class from that DAL assembly; B) is injected into a website class by Windsor. I will work on adding some sample code to this question, but wanted to put it out in case it's obvious what I do wrong.

• Dynamic table memory usage

  - by Dan

  I use a dynamic table: <html> <body> <button id="button">Build table</button> <div id="container"> <script type="text/javascript"> window.onload=function(){ var table = null; var row = "<tr><td>111111111111111111111111111111111111111111111111111111</td>" + "<td>222222222222222222222222222222222222222222222222222222</td>" + "<td>333333333333333333333333333333333333333333333333333333</td></tr>"; var data = null; for (var i = 0; i < 2000; i++){ data += row; } var obj = document.getElementById("button"); obj.onclick=function buildTable(){ document.getElementById("container").innerHTML = "<div><table><tbody>" + data + "</tbody></table></div>"; }; }; </script> </body> </html> Using chromes task manager, each time new data is loaded the memory usage increases considerably and doesn't go down, so after some time the app consumes a lot of memory and requires the browser to be closed. Is there any change in the code I can use to solve this or is it a browser side problem?

• How to combine two separate unrelated Git repositories into one with single history timeline

  - by Antony

  I have two unrelated (not sharing any ancestor check in) Git repositories, one is a super repository which consists a number of smaller projects (Lets call it repository A). Another one is just a makeshift local Git repository for a smaller project (lets call it repository B). Graphically, it would look like this A0-B0-C0-D0-E0-F0-G0-HEAD (repo A) A0-B0-C0-D0-E0-F0-G0-HEAD (remote/master bare repo pulled & pushed from repo A) A1-B1-C1-D1-E1-HEAD (repo B) Ideally, I would really like to merge repo B into repo A with a single history timeline. So it would appear that I originally started project in repo A. Graphically, this would be the ideal end result A0-A1-B1-B0-D1-C0-D0-E0-F0-G0-E1-H(from repo B)-HEAD (new repo A) A0-A1-B1-B0-D1-C0-D0-E0-F0-G0-E1-H(from repo B)-HEAD (remote/master bare repo pulled & pushed from repo A) I have been doing some reading with submodules and subtree (Pro Git is a pretty good book by the way), but both of them seem to cater solution towards maintaining two separate branch with sub module being able to pull changes from upstream and subtree being slightly less headache. Both solution require additional and specialized git commands to handle check ins and sync between master and sub tree/module branch. Both solution also result in multiple time-lines (with --squash you even get 3 timelines with subtree). The closest solution from SO seems to talk about "graft", but is that really it? The goal is to have a single unified repository where I can pull/push check-ins, so that there are no more repo B, just repo A in the end.

• iphone - why is this flip animation using layers not working?

  - by Digital Robot

  I would like to make an animation that goes like this: imagine a picture sitting on a shelve. It drops from the shelve and as it falls it rotates along the horizontal axis and translates along the vertical axis. I would like to do this with perspective and the back side should be the image reversed, like the picture is a kind of slide. I have done this: CALayer* layer = myImageView.layer; layer.doubleSided = YES; CAKeyframeAnimation* animationTransform = [CAKeyframeAnimation animationWithKeyPath:@"transform"]; CATransform3D startTransform = CATransform3DIdentity; CATransform3D endTransform = CATransform3DTranslate (layer.transform, 0.0f, 200.0f, 0.0f); endTransform = CATransform3DRotate (endTransform, degreesToRadian(350.0f), 1.0f, 0.0f, 0.0f); endTransform.m34 = 1.0 / -500; NSArray *values = [NSArray arrayWithObjects: [NSValue valueWithCATransform3D:startTransform], [NSValue valueWithCATransform3D:endTransform], nil]; [animationTransform setValues:values]; NSArray *tempos = [NSArray arrayWithObjects: [NSNumber numberWithFloat:0.0f], [NSNumber numberWithFloat:0.7f], nil]; [animationTransform setKeyTimes:tempos]; NSArray *timing = [NSArray arrayWithObjects: [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut], nil]; [animationTransform setTimingFunctions:timing]; animationTransform.fillMode = kCAFillModeRemoved; animationTransform.removedOnCompletion = YES; animationTransform.repeatCount = 1; animationTransform.duration = 3.7f; animationTransform.cumulative = YES; the result of this has nothing to do with anything. The result is: the image translates down an inch on the screen and then up half inch. Then it disappears and appears at its starting position again. What am I missing? thanks

• Breaking dependencies when you can't make changes to other files?

  - by codemuncher

  I'm doing some stealth agile development on a project. The lead programmer sees unit testing, refactoring, etc as a waste of resources and there is no way to convince him otherwise. His philosophy is "If it ain't broke don't fix it" and I understand his point of view. He's been working on the project for over a decade and knows the code inside and out. I'm not looking to debate development practices. I'm new to the project and I've been tasked with adding a new feature. I've worked on legacy projects before and used agile development practices with good result but those teams were more receptive to the idea and weren't afraid of making changes to code. I've been told I can use whatever development methodology I want but I have to limit my changes to only those necessary to add the feature. I'm using tdd for the new classes I'm writing but I keep running into road blocks caused by the liberal use of global variables and the high coupling in the classes I need to interact with. Normally I'd start extracting interfaces for these classes and make their dependence on the global variables explicit by injecting them as constructor arguments or public properties. I could argue that the changes are necessary but considering the lead never had to make them I doubt he would see it my way. What techniques can I use to break these dependencies without ruffling the lead developer's feathers? I've made some headway using: Extract Interface (for the new classes I'm creating) Extend and override the wayward classes with test stubs. (luckily most methods are public virtual) But these two can only get me so far.

• Ninject: How do I inject into a class library ?

  - by DennyDotNet

  To start I'm using Ninject 1.5. I have two projects: Web project and a Class library. My DI configuration is within the Web project. Within my class library I have the following defined: public interface ICacheService<T> { string Identifier { get; } T Get(); void Set( T objectToCache, TimeSpan timeSpan ); bool Exists(); } And then a concrete class called CategoryCacheService. In my web project I bind the two: Bind( typeof( ICacheService<List<Category>> ) ).To( typeof(CategoryCacheService)).Using<SingletonBehavior>(); In my class library I have extension methods for the HtmlHelper class, for example: public static class Category { [Inject] public static ICacheService Categories { get; set; } public static string RenderCategories(this HtmlHelper htmlHelper) { var c = Categories.Get(); return string.Join(", ", c.Select(s = s.Name).ToArray()); } } I've been told that you cannot inject into static properties, instead I should use Kernel.Get<() - However... Since the code above is in a class library I don't have access to the Kernel. How can I get the Kernel from this point or is there a better way of doing this? Thanks!

• Suggestions on error handling of Win32 C++ code: AtlThrow vs. STL exceptions

  - by EmbeddedProg

  In writing Win32 C++ code, I'd appreciate some hints on how to handle errors of Win32 APIs. In particular, in case of a failure of a Win32 function call (e.g. MapViewOfFile), is it better to: use AtlThrowLastWin32 define a Win32Exception class derived from std::exception, with an added HRESULT data member to store the HRESULT corresponding to value returned by GetLastError? In this latter case, I could use the what() method to return a detailed error string (e.g. "MapViewOfFile call failed in MyClass::DoSomething() method."). What are the pros and cons of 1 vs. 2? Is there any other better option that I am missing? As a side note, if I'd like to localize the component I'm developing, how could I localize the exception what() string? I was thinking of building a table mapping the original English string returned by what() into a Unicode localized error string. Could anyone suggest a better approach? Thanks much for your insights and suggestions.
