• What is your strategy to avoid dynamic typing errors in Python (NoneType has no attribute x)?

  - by Koen Bok

  Python is one of my favorite languages, but I really have a love/hate relationship with it's dynamicness. Apart from the advantages, it often results in me forgetting to check a type, trying to call an attribute and getting the NoneType (or any other) has no attribute x error. A lot of them are pretty harmless but if not handled correctly they can bring down your entire app/process/etc. Over time I got better predicting where these could pop up and adding explicit type checking, but because I'm only human I miss one occasionally and then some end-user finds it. So I'm interested in your strategy to avoid these. Do you use type-checking decorators? Maybe special object wrappers? Please share...

• Best practice? iphone: sync data

  - by Andy Jacobs

  So i'm working on a project where there is data visualization. My ultimate goal is that i have a set of data shipped with the download of the iphone app. But i want it connected to a backend, that if the iphone has a connection with the internet. it can sync the changes from the backend. The syncing is no problem or the connection between the backend & the iphone. But what should i use as data storage on my iphone? what is the best way. my data is purely text and doesn't have to be secure. But it's main feature should be updating certain parts of data ( adding and deleting are not so important ) so what is the easiest (read: least time consuming development ) or the best way? sqlite? plist? ..?

• problems with user control page

  - by Alexander

  I am starting to give up troubleshooting this issue I had... I had an .ascx page and had the following user control in it: <td> <Club:DatePicker ID="dp1" runat="server" /> </td> however in my code behind when I tried to write methods: public System.DateTime startDateTime { get { return dp1.SelectedDate.Add(tp1.SelectedTime.TimeOfDay); } set { dp1.SelectedDate = value; tp1.SelectedTime = value; } } It can't reference dp1(dp1 is underlined in red) as well as tp1... why is this?? I've tried to convert the solution to a web application and yet it doesn't work. Tried adding: protected global::ClubSite dp1; protected global::ClubSite tp1; in the ascx.designer.cs but then the global is highlighted in red here's the link to my full solution: http://cid-1bd707a1bb687294.skydrive.live.com/self.aspx/.Public/Permias.zip

• can i change membership provider GetAllUsers method?

  - by Tones

  Hi i am using vb.net and the .net membership provider. i want to bring back a gridview with user account information, like GetAllUsers() does. However i want to only bring back users with certain profile information, that will be users whos profile information matches the selected value in a dropdownlist on the same page. I am using profile provider to record just one extra piece of user information. Can i change or override the GetAllUsers method for this? Adding an extra parameter so its GetAllUsers by Profile. Membership has a FindUsersByName method, i want to do something similar with users by Profile. I am very much a noob with .net programming so i hope i have explained this ok.

• Drupal, Views: display taxonomies as Views titles.

  - by Patrick

  hi, I'm using Views for some nodes, and I want to display a different View title according to which taxonomy tags are selected in my filter. I already have taxonomy field for each node in my view. But this is not what I need. I basically need to display all the currently filtered tags on the top of my view. I was wondering if I can solve adding some line with php, how ? Thanks Update: I'm now using the Views Header field in Views settings, but it only processes html code, not php, so I cannot add taxonomy terms. Is it because of my CCK Editor settings ? thanks

• Attempt to set foreign key to nonexistent table, sf_guard_user!

  - by Stick it to THE MAN

  I am using SF 1.3.2 with Propel ORM on Ubuntu 9.10. I created a new SF project and simply copied the sfGuard plugin folder from a pre-existing SF 1.32 project. I manually edited the schema.yml in the new project, adding a user table that reference the the sfGuard table. When I run propel:build-sql, I got the task failed, with the error message: Attempt to set foreign key to nonexistent table, sf_guard_user! I'm not sure why this error is occurring, (the error dosent make sense to me, since the sfGuard plugin works fine with the previous project, with no changes made. what am I missing?? BTW, I have not created any apps in the project yet. I am just running the build-sql task first, to make sure that Propel has no problems with parsing my yml files etc.

• Add mask to input

  - by Lodewijk Wensveen

  I'm trying to achieve the seemingly impossible task of adding an mask to a input field. I have the following code: function addActivationCode(){ newRow = jQuery("div.activationcode:last-child").clone(); newRow.insertAfter(jQuery("div.activationcode:last-child")); newRow.attr("id", "coderow-" + Math.round(Math.random() * 10000)); newRow.find("input").val(""); find("input").mask("9999-9999-9999-9999"); newRow.find("a.coderemove").attr("onclick", "removeActivationCode('" + newRow.attr("id") + "'); return false;"); } function removeActivationCode(id){ jQuery("div#" + id).remove(); } Now I to get the .mask working on my input fields, so far I've only got it working on the new row I'm making and not on the original one. Can anyone help me out?

• detecting circular imports

  - by wallacoloo

  I'm working with a project that contains about 30 unique modules. It wasn't designed too well, so it's common that I create circular imports when adding some new functionality to the project. Of course, when I add the circular import, I'm unaware of it. Sometimes it's pretty obvious I've made a circular import when I get an error like AttributeError: 'module' object has no attribute 'attribute' where I clearly defined 'attribute'. But other times, the code doesn't throw exceptions because of the way it's used. So, to my question: Is it possible to programmatically detect when and where a circular import is occuring?

• HOWTO and best working installation (MSI) chainer +/ bootstrapper

  - by davidovitz

  Hi, Our product has several products that customer can install created as separate installation packages (MSI). We have a requirement to have single package for the installation that will: Show one UI with progress Allow user to choose which features/packages to install Have ability to constrain one feature to another (e.g removing or adding effect other) Support single elevation (UAC) nice to have ability to auto update (not must) support command line + silent installation the package should be built out of the isolated installations (chain them) raise error / messages for missing prerequisites Support patches over time and major upgrades Today we do almost all of the above using MSI with nested installations which is bad practice and we face too many issues in our solution. i know that there are several bootstrappers out there (m$ generic bootstrapper which i think is not good, BURN is the WIX version which is not mature enough) Do you know of other? that work and tested already ? What is the best method to do (without unification of the MSI into a single MSI)

• Tinyxml Multi Task

  - by shaimagz

  I have a single xml file and every new thread of the program (BHO) is using the same Tinyxml file. every time a new window is open in the program, it runs this code: const char * xmlFileName = "C:\\browsarityXml.xml"; TiXmlDocument doc(xmlFileName); doc.LoadFile(); //some new lines in the xml.. and than save: doc.SaveFile(xmlFileName); The problem is that after the first window is adding new data to the xml and saves it, the next window can't add to it. although the next one can read the data in the xml, it can't write to it. I thought about two possibilities to make it work, but I don't know how to implement them: Destroy the doc object when I'm done with it. Some function in Tinyxml library to unload the file. Any help or better understanding of the problem will be great. Thanks.

• Overriding SQLMembershipProvider

  - by vikp

  Is there built in methods into .net framework to do the following: Get role GUID from user name/user GUID Get role name from role GUID So far I have been sending queries to the asp_roles and asp_users tables to obtain that information and I'm wondering if there is a nicer way of doing this? I have the following methods that I store in the ASPUtilities class: getRoleGUID(guid userGuid) { LINQ joins } getRoleGuid(string userName) { LINQ joins } getRoleName(guid roleGuid) { LINQ joins } EDIT: I have just looked into extending SQLMembershipProvider examples. Few examples completely override the SQLMembershipProvider, but I think what I'm interested is just adding few extra methods to deal with the roles by using LINQ. Is this feasible?

• Problem with numbers

  - by StolePopov

  I am given a number N, and i must add some numbers from the array V so that they wil be equal. V is consisting of numbers that are all powers of 3: N = 17 S = 0 V = 1 3 9 27 81 .. I should add numbers from V to N and S in order to make them equal. The solution to the example above is : 17 + 1 + 9 = 27, 27, 1 and 9 are taken from V, a number from V can be taken only once, and when taken it's removed from V. I tried sorting V and then adding the biggest numbers from V to S until S has reached N, but it fails on some tests when it's like: N = 7 S = 0 V = 1 3 9 27 So the solution will be: 7 + 3 = 9 + 1 In examples like this i need to add numbers both to N and S, and also select them so they become equal. Any idea of solving this ? Thanks.

• How to properly use .SWC packages in Flash CS 4

  - by DevEight

  Hi! I've googled a lot trying to find how to properly import and use .swc files in Flash CS 4, tried lots of different methods but none seem to work. What I've done is: 1. Placed it in my "D:\Program Files (x86)\Adobe\Adobe Flash CS4\en\Configuration\Components" folder. It does however not show up in the component inspector. 2. Added it in Publishing Settings as a Library and External Library, still can't seem to use it. I've also tried adding "import org.osflash.signals;" after each method but I receive the error "1172: Definition org.osflash:signals could not be found." So what I'm asking for is an easy way to get the .swc package working code-wise with all classes imported etc. The .swc file is as you may have guessed as3signals. Thanks in advance.

• Microsoft.Biztalk.explorerom.dll reference in asp.net application resulting system.nullreferenceexce

  - by sheetal.oza

  Hi, I have a asp.net application in order to start/stop applications and ports of Biztalk server 2006 r2. I have used "Microsoft.Biztalk.explorerom.dll (C:/Program Files/Biztalk Server 2006/Developer tool) " to achieve this. This is working fine on development machine since biz talk server is installed on local machine. But in the production environment (asp.net web server ,windows 2003 and iis 6.0)...this give System.nullreferenceexception (object reference not set..) at BtsCatalogExplorer explorer = (BtsCatalogExplorer)myGroup.CreateInstance(typeof(BtsCatalogExplorer)) my biztalk server and sql server are on two different box. In my setup (asp.net web application)..adding Microsoft.Biztalk.explorerom.dll and Microsoft.Biztalk.Applicationdeployment.engine.dll to GAC. But still no luck. Do i need to install biz talk server on my local machine even though I am connecting to different biz talk server?? And help is appreciated...

• Modifying CollectionEditor in PropertyGrid

  - by Chris

  I currently have a list containing Call's, which is the base class. If I want to add derived classes of Call to the list, I know to do the following. public class CustomCollectionEditor : System.ComponentModel.Design.CollectionEditor { private Type[] types; public CustomCollectionEditor(Type type) : base(type) { types = new Type[] { typeof(Call), typeof(CappedCall) }; } protected override Type[] CreateNewItemTypes() { return types; } } public class DisplayList { public DisplayList() { } [Editor(typeof(CustomCollectionEditor), typeof(UITypeEditor))] [DataMember] public List<Call> ListCalls { get; set; } } My questions is there anyway of moving where you mark up the Type[] containing all possible types the list can contain? I thought of adding the following to my CustomCollectionEditor class, but this doesn't work. public CustomCollectionEditor(Type type, List<Type> types_) : base(type) { types = types_.ToArray(); } It would be ideal if I could mark up which classes the CustomCollectionEditor needed to be aware of in the DisplayList class somehow.

• inject a mockups to a bean that has @autowired annotations

  - by santiagozky

  I have a bean that has a couple of beans injected with the autowire annotation (no qualifier). Now, for testing reasons I want to inject some mocks to the bean instead of the ones being autowired (some DAOs). Is there any way I can change which bean is being injected without modifying my bean? I don't like the idea of adding annotations my code just to test it and then remove then for production. I am using spring 2.5. The bean look like this: @Transactional @Service("validaBusinesService") public class ValidaBusinesServiceImpl implements ValidaBusinesService { @Autowired OperationDAO operationDAO; @Autowired BinDAO binDAO; @Autowired CardDAO cardDAO; @Autowired UserDAO userDAO; ... ... }

• Disabling scoring in Lucene(.NET)

  - by user72185

  Hi, When searching, is there a way to disable scoring for any query? The scenario is that the user refines his query by trying different combinations of words, phrases etc., and needs realtime (well, reasonably fast at least) responses on the number of hits. Search time slows down a lot when there are millions of hits due to scoring, but the user really doesn't care about all these documents. As soon as he sees there are 1M+ hits he will start adding additional words to the query. A "Sort by relevance" option would allow him to do this quickly, while turning scoring back on when the number of hits is reasonable. Is this possible? I'm using Lucene.NET 2.9.2 but AFAIK it is identical to the Java version.

• Traverse list to add elements, C#.

  - by Addie

  I have a list of objects. Each object has an integer quantity and a DateTime variable which contains a month and year value. I'd like to traverse the list and pad the list by adding missing months (with quantity 0) so that all consecutive months are represented in the list. What would be the best way to accomplish this? Example: Original List { Jan10, 3 }, { Feb10, 4 }, { Apr10, 2 }, { May10, 2 }, { Aug10, 3 }, { Sep10, -3 }, { Oct10, 6 }, { Nov10, 3 }, { Dec10, 7 }, { Feb11, 3 } New List { Jan10, 3 }, { Feb10, 4 }, {Mar10, 0}, { Apr10, 2 }, { May10, 2 }, { Jun10, 0 }, { Jul10, 0 } { Aug10, 3 }, { Sep10, -3 }, { Oct10, 6 }, { Nov10, 3 }, { Dec10, 7 }, { Jan11, 0 }, { Feb11, 3 }

• Postgresql 8.4 reading OID style BLOBs with Hibernate

  - by peter

  I am getting this weird case when querying Postgres 8.4 for some records with Blobs (of type OIDs) with Hibernate. The query does return all right but when my code wants to read the content of the BLOB with the simple code below, it gets 0 bytes back public static byte[] readBlob(Blob blob) throws Exception { InputStream is = null; try { is = blob.getBinaryStream(); return org.apache.commons.io.IOUtils.toByteArray(is); } finally { if (is != null) try { is.close(); } catch(Exception e) {} } } Funny think is that I am getting this behavior only since I've started adding more then one such records to the table. The underlying JDBC library is type 3 (postgresq 8.4-701). Can someone give me a hint as to how to solve this issue? Thanks Peter

• Capture Silverlight 4 event when panel clicked

  - by Eric J.

  I have a small Silverlight 4 app that essentially consists of a grid containing a label and a combo box. When I click the label, I replace it with a second text box so that I can edit the label (much the way you can edit the name of a Silverlight control in VS2010). I have a LostFocus event handler on the text box that will end editing when the control loses focus (restoring the updated label). Trouble is, users tend to click on the panel when they are done editing rather than on another control (or hitting Enter, which is also supported). I tried adding a left mouse down event handler to the panel. However, that only fires when the text box does not have the focus (I guess the text box captured the mouse?) Is there an approach to recognize that a non-input control was clicked that would enable me to terminate edit mode?

• Missing [mx.rpc]::IResponder

  - by Arms

  I'm trying to use the Flex 4 SDK's mx.rpc package in a Flash application. I imported Flex's rpc.swc (Adobe\Adobe Flash Builder 4\sdks\4.0.0\frameworks\libs\rpc.swc) into my project by adding it to the list in Flash's "Publish Settings/Flash/ActionScrip 3.0 Settings/Library Path". It seems like I have access to the classes, however when I compile I get this error: 1046: Type was not found or was not a compile-time constant: [mx.rpc]::IResponder. There's no location or line for the error either. Any idea how to get this to work? TIA! Notes: I'm using Flash Builder 4 and Flash CS5

• How to remove previous versions of Xcode

  - by Ed Marty

  When the 3.2 beta of the iPhone OS first came out, Xcode for 3.2 had to be installed side-by-side with the version for 3.1.2. I installed the new version (3.2) in /Developer and moved 3.1.2 to /Xcode3.1.2. Now I want to get rid of the old version and just use the new one since we can do that now. I ran the uninstall tool at /Xcode3.1.2/Library/uninstall-devtools and uninstall-developer-folder, but the directory still exists and has lots of stuff still in it, adding up to about 5 GB. At this point, am I safe just deleting the folder if I want to totally get rid of it and still use the /Developer folder? (At about 8 GB, it's got lots more in it, but I'm not sure if that's just because it's larger or because the old version was 8 GB before I ran the uninstall tool)?

• MKReverseGeocoder delegate location?

  - by fuzzygoat

  I have a quick question regarding memory management that I am not quite sure about. I currently have a locationManager delegate that calls locationManager:didUpdateToLocation:fromLocation when it resolves the device location. My question is I am looking at adding ReverseGeoCoding after I have obtained the [newLocation coordinate] but am unsure about doing the alloc here, as each time locationManager:didUpdateToLocation:fromLocation gets called I will be alloc-ing a new MKReverseGeoCoder? // LOCATION -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { // GeoCoding: MKReverseGeocoder *geoCoder = [[MKReverseGeocoder alloc] initWithCoordinate:[newLocation coordinate]]; [geoCoder setDelegate:self]; [geoCoder start]; [self foundLocation]; } Can anyone point me in the right direction with regards to this? I did try doing the alloc in application:didFinishLaunchingWithOptions: but then realised I did not have access to [newLocation coordinate]. many thanks gary

• recaptcha asp.net always returns invalid

  - by Curtis White

  The reCaptcha example for ASP.NET does not seem to work. I followed the instructions but it always returns false, "The verification words are incorrect.". The entries are good. I'm using localhost as the site but am not getting any public/private key errors which I did get when adding a bad key (as a test). I've seen this error reported a lot but no good answers. Some suggest to call the validate on the control before checking to see if it is valid but this did not work for me.
