• How do I send user to a URI on MouseLeftButtonUp?

  - by Byron Sommardahl

  This question is for Windows Phone 7. I'd like to send the user to a specific external URI when the entire ListBox item is clicked (not HyperLinkButton). I already have a MouseLeftButtonUp event handler for the item. At this point, I can't find a way to navigate the user to the URI.

• What are options for GWT to C++ communication?

  - by seas

  I am looking for GWT to C++ communication solution. Currently I am trying to figure out how to run WSDL in GWT, but actually, have absolutely no experience in WSDL, and only little in GWT. So, my question is about feasibility of working with WSDL in GWT (and how?) and other approaches would also be interesting if exist. I am trying to avoid coding Java on the server and coding JavaScript on client.

• Is it possible to run a php soap api operation in a web browser

  - by user294873

  In axis2 on Java it's possible to run operations in the browser by the way you send the url for example localhost:8080/axis2/services/SimpleService?wsdl could have operations implemented by writing urls like so localhost:8080/axis2/services/SimpleService/hello?param0=xxx My Question is can you do the same in PHP5 SoapServer where the url is as below? localhost/soaptest/index.php?wsdl Thanks

• Is a many-to-many relationship with extra fields the right tool for my job?

  - by whichhand

  Previously had a go at asking a more specific version of this question, but had trouble articulating what my question was. On reflection that made me doubt if my chosen solution was correct for the problem, so this time I will explain the problem and ask if a) I am on the right track and b) if there is a way around my current brick wall. I am currently building a web interface to enable an existing database to be interrogated by (a small number of) users. Sticking with the analogy from the docs, I have models that look something like this: class Musician(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) dob = models.DateField() class Album(models.Model): artist = models.ForeignKey(Musician) name = models.CharField(max_length=100) class Instrument(models.Model): artist = models.ForeignKey(Musician) name = models.CharField(max_length=100) Where I have one central table (Musician) and several tables of associated data that are related by either ForeignKey or OneToOneFields. Users interact with the database by creating filtering criteria to select a subset of Musicians based on data the data on the main or related tables. Likewise, the users can then select what piece of data is used to rank results that are presented to them. The results are then viewed initially as a 2 dimensional table with a single row per Musician with selected data fields (or aggregates) in each column. To give you some idea of scale, the database has ~5,000 Musicians with around 20 fields of related data. Up to here is fine and I have a working implementation. However, it is important that I have the ability for a given user to upload there own annotation data sets (more than one) and then filter and order on these in the same way they can with the existing data. The way I had tried to do this was to add the models: class UserDataSets(models.Model): user = models.ForeignKey(User) name = models.CharField(max_length=100) description = models.CharField(max_length=64) results = models.ManyToManyField(Musician, through='UserData') class UserData(models.Model): artist = models.ForeignKey(Musician) dataset = models.ForeignKey(UserDataSets) score = models.IntegerField() class Meta: unique_together = (("artist", "dataset"),) I have a simple upload mechanism enabling users to upload a data set file that consists of 1 to 1 relationship between a Musician and their "score". Within a given user dataset each artist will be unique, but different datasets are independent from each other and will often contain entries for the same musician. This worked fine for displaying the data, starting from a given artist I can do something like this: artist = Musician.objects.get(pk=1) dataset = UserDataSets.objects.get(pk=5) print artist.userdata_set.get(dataset=dataset.pk) However, this approach fell over when I came to implement the filtering and ordering of query set of musicians based on the data contained in a single user data set. For example, I could easily order the query set based on all of the data in the UserData table like this: artists = Musician.objects.all().order_by(userdata__score) But that does not help me order by the results of a given single user dataset. Likewise I need to be able to filter the query set based on the "scores" from different user data sets (eg find all musicians with a score 5 in dataset1 and < 2 in dataset2). Is there a way of doing this, or am I going about the whole thing wrong?

• remote class alias in air

  Hi in Flex one can easily define the remote class alias like the following: package samples.portfolio { [RemoteClass(alias="flex.samples.marketdata.Stock")] [Bindable] public class Stock { public var symbol:String; public var name:String; public var low:Number; } } But my question is how do you do it in AIR since the client app does not know about the server file structure.

• How to tell where I am in an array with pointer arythmetic?

  - by klez

  In C, I have declared a memory area like this: int cells = 512; int* memory = (int*) malloc ((sizeof (int)) * cells); And I place myself more or less in the middle int* current_cell = memory + ((cells / 2) * sizeof (int)); My question is, while I increment *current_cell, how do I know if I reached the end of the allocated memory area?

• TinyMCE Custom Tags Rendering

  I have add a custom plugin that insert custom tags into my tinyMCE editor of the format: title I want the custom tags to be rendered with some styles when viewed in the WYSIWYG view. I have seen one response to a similar question : http://topsecretproject.finitestatemachine.com/2010/02/how-to-custom-tags-with-tinymce/ but this doesn't work - they tags are not stripped out but they are not styled either??

• Which is clearer form: if(!value) or if(flag == value) ?

  - by CodexArcanum

  I understand this is a subjective question, so I apologize if it needs to be closed, but I feel like it comes up often enough for me to wonder if there is a general preference for one form over the other. Obviously, the best answer is "refactor the code so you don't need to test for falsehood" but sometimes there's no easy way to do so and the "else" branch is simply to continue processing. So when you must have an "if not false" construct, which is the preferred standard: The not operator if(!value) Or the test for false if(value == false)

• How can I show the contents of a file at a specific state of a git repo?

  - by richcollins

  I want to show the contents of a file given by a path at a specific state of a git repo. I unsuccessfully tried this: git show f825334150cd4bc8f46656b2daa8fa1e92f7796d:Katana/source/Git/GitLocalBranch.h fatal: ambiguous argument 'f825334150cd4bc8f46656b2daa8fa1e92f7796d:Katana/source/Git/GitLocalBranch.h': unknown revision or path not in the working tree. Use '--' to separate paths from revisions The commit in question didn't modify the file specified. How can I show the contents of a file at a given state (specified by a commit hash) regardless of the involvement of the file in the commit?

• .NET Free memory usage (how to prevent overallocation / release memory to the OS)

  - by Ronan Thibaudau

  I'm currently working on a website that makes large use of cached data to avoid roundtrips. At startup we get a "large" graph (hundreds of thouthands of different kinds of objects). Those objects are retrieved over WCF and deserialized (we use protocol buffers for serialization) I'm using redgate's memory profiler to debug memory issues (the memory didn't seem to fit with how much memory we should need "after" we're done initializing and end up with this report Now what we can gather from this report is that: 1) Most of the memory .NET allocated is free (it may have been rightfully allocated during deserialisation, but now that it's free, i'd like for it to return to the OS) 2) Memory is fragmented (which is bad, as everytime i refresh the cash i need to redo the memory hungry deserialisation process and this, in turn creates large object that may throw an OutOfMemoryException due to fragmentation) 3) I have no clue why the space is fragmented, because when i look at the large object heap, there are only 30 instances, 15 object[] are directly attached to the GC and totally unrelated to me, 1 is a char array also attached directly to the GC Heap, the remaining 15 are mine but are not the cause of this as i get the same report if i comment them out in code. So my question is, what can i do to go further with this? I'm not really sure what to look for in debugging / tools as it seems my memory is fragmented, but not by me, and huge amounts of free spaces are allocated by .net , which i can't release. Also please make sure you understand the question well before answering, i'm not looking for a way to free memory within .net (GC.Collect), but to free memory that is already free in .net , to the system as well as to defragment said memory. Note that a slow solution is fine, if it's possible to manually defragment the large heap i'd be all for it as i can call it at the end of RefreshCache and it's ok if it takes 1 or 2 second to run. Thanks for your help! A few notes i forgot: 1) The project is a .net 2.0 website, i get the same results running it in a .net 4 pool, idem if i run it in a .net 4 pool and convert it to .net 4 and recompile. 2) These are results of a release build, so debug build can not be the issue. 3) And this is probably quite important, i do not get these issues at all in the webdev server, only in IIS, in the webdev i get memory consumption rather close to my actual consumption (well more, but not 5-10X more!)

• Is it correct or incorrect for a Java JAR to contain its own dependencies?

  - by 4herpsand7derpsago

  I guess this is a two-part question. I am trying to write my own Ant task (MyFirstTask) that can be used in other project's build.xml buildfiles. To do this, I need to compile and package my Ant task inside its own JAR. Because this Ant task that I have written is fairly complicated, it has about 20 dependencies (other JAR files), such as using XStream for OX-mapping, Guice for DI, etc. I am currently writing the package task in the build.xml file inside the MyFirstTask project (the buildfile that will package myfirsttask.jar, which is the reusable Ant task). I am suddenly realizing that I don't fully understand the intention of a Java JAR. Is it that a JAR should not contain dependencies, and leave it to the runtime configuration (the app container, the runtime environment, etc.) to supply it with the dependencies it needs? I would assume if this is the case, an executable JAR is an exception to the rule, yes? Or, is it the intention for Java JARs to also include their dependencies? Either way, I don't want to be forcing my users to be copying-n-pasting 25+ JARs into their Ant libs; that's just cruel. I like the way WAR files are set up, where the classpath for dependencies is defined under the classes/ directory. I guess, ultimately, I'd like my JAR structure to look like: myfirsttask.jar/ com/ --> the root package of my compiled binaries config/ --> config files, XML, XSD, etc. classes/ --> all dependencies, guice-3.0.jar, xstream-1.4.3.jar, etc. META-INF/ MANIFEST.MF I assume that in order to accomplish this (and get the runtime classpath to also look into the classes/ directory), I'll need to modify the MANIFEST.MF somehow (I know there's a manifest attribute called ClassPath, I believe?). I'm just having a tough time putting everything together, and have a looming/lingering question about the very intent of JARs to begin with. Can someone please confirm whether Oracle intends for JARs to contain their dependencies or not? And, either way, what I would have to do in the manifest (or anywhere else) to make sure that, at runtime, the classpath can find the dependencies stored under the classes/ directory? Thanks in advance!

  Hello, I am newbie to jQuery, just trying to learn it since last couple of days. In my office, there are few experience JavaScript Developer and they work mainly with jQuery for all their needs and whenever I got and talk to them to get some better understanding of how jQuery works and first they say is that on $(document).(ready) you do this and on $(document).(ready) you do that. So my main question is What is the $(document).(ready) and how does it really works ? Any inputs would be highly appreciated.

• Entitlement Web Service Authentication

  - by jesusOmar

  I was tasked with implementing either a SAML authentication service, or a EWS (Entitlement Web Service Authentication) service, and I was wondering if anyone has any samples or documentation on such options. I am almost 100% sure that SAML is out of the question due to the time frame of the project. EWS has been difficult to find online, I can't seem to find any good samples or documentation on implementing such service.

• Database structure for versioning and multiple languages

  - by phobia

  How can I solve the issue of content existing in multiple versions and multiple languages? My current structure: Each content can only have one active version in each language, and that's how I'm curious on how to best solve. Right now I have a column of the contentversions table, which means for each change of active version I have to run a update and set active=false on all version and then a update to set active=true for the piece of content in question.

• Best way to display a background with a pattern in an iPhone/iPad app

  - by Dr Dork

  Here's an example of the type of background image I'm talking about... Clearly, there's a pattern in it. My question is, if this were an iPad app and the background image was twice the size, would there be any significant benefits to taking advantage of this pattern by tiling the image? Or would it really make no difference in terms of performance and just be easier to load the entire image into a UIImageView? Thanks in advance for all your wisdom!

• Why membership provider is not generic?

  - by Timmy O' Tool

  I have to confess that I hate membership provider. The default implementation is not very appropriate normally and I haven't seen so far a good implementation of a custom membership provider, probably because this is not possible :-) So the question is: In your opinion: which are the reasons for not having membership/role provider as a generic class? I mean, why Microsoft didn't selected this approach.

• Checking for nulls in ASP.NET MVC Controllers

  - by Brian McCord

  Another opinion question: What is the proper (in your opinion) to check for nulls in an MVC controller. For instance, if you have an edit controller that fetches a record from the db based on an id, what do you do if that record is not found? I found this article, but I'm not sure I like that method. Do you just check for it with an if statement and redirect to a 404 page? What solution do you use?
