• How to setup Xcode 3.1.4 with Perforce ?

  - by Azeworai

  Hi everyone, I've been trying to setup Xcode with Perforce for about 7 hours now and managed to get the Perforce Repository Authenticated within Xcode. The problem I have is, within the repositories window, I don't see any directories for me to check out. I can see the p4root login and client are ok with the tick on the repository log. When I try to Import an xcode project directory within the Perforce root directory- the import fails with '/Users/jackson/p4root/alpha/MessageTapper' is not under the Perforce root. I have p4d running on the local machine, and have created a user and workspace. The workspace has the directories in view. I'm hoping for someone to give me some direction or maybe point me to a good reference to how to set perforce up with xcode. Thanks!

• jqplot format tooltip values

  - by Jeroen

  I want to have a tooltip hover highlight thingy in jqplot. The problem is that I want it to give more detail then on the axes. So the formatter should be different. I can't get it to display the seconds to: There's a JS fidle here! I want the timestamp to display as hours:minutes:seconds, which would be format string '%H:%M:%S' or '%T' or '%X'. But how do I do that? highlighter: { show: true, sizeAdjust: 3, //useAxesFormatters: false, //tooltipFormatString: '%H:%M:%S', formatString: '<table class="jqplot-highlighter"><tr><td>tijd:</td><td>%s</td></tr><tr><td>snelheid:</td><td>%s</td></tr></table>', },

• How to draw/manage a hexagon grid?

  - by W.N.

  I've read this article: generating/creating hexagon grid in C . But look like both the author and answerer have already abandoned it. v(hexagonSide - hexagonWidth * hexagonWidth): What's hexagonSide and hexagonWidth? Isn't it will < 0 (so square root can't be calculated). And, can I put a hexagon into a rectangle? I need to create a grid like this: One more thing, how can I arrange my array to store data, as well as get which cells are next to one cell? I have never been taught about hexagon, so I know nothing about it, but I can easily learn new thing, so if you can explain or give me a clue, I may do it myself.

• dynamic html "more information" callout / annotation (jquery? ajax control toolkit?)

  - by nailitdown

  Hola, I have an app i'm building in c#, and i'd like to have the ability to have a user click a "more information" icon next to a field, which will then show a callout with some blurb about why the field contains what it does. ideally it'd look a lot like the ValidatorCallout, but instead of being shown as a result of validation, it'll be shown as a result of a mouseclick, or hover. Anyone know of a nice way to do this with either the ajaxcontroltoolkit, or jquery? cheers for any help you can give me.

• Do you take the pain of learning it or use an out of the box solution?

  - by Mantorok

  Hi all What I'm getting at here is being presented with a control or framework that does 95% of what you want but has its shortcomings when opposed to learning how to do it yourself. To give a good example (ASP.Net) UpdatePanel vs DIY JS/JSON. The UpdatePanel gives you AJAX instantly without doing anything additional, however I've come to learn that its shortcomings are mainly that it's a bit of a hack and performs badly on busy pages and I've found myself having to scrap UpdatePanels in favour of rolling my own JS, and I've now made it a habit to fully investigate any shortcomings in out-of-the-box solutions, as I've been stung by this experience. So I guess what I'm asking is: Is it better to find out how to DIY or is it considered a better approach to try the available solution and risk going a full circle? Obviously I've only targetted a single control, but it is a very attractive control to people learning AJAX - I'm sure there are others out there. Sorry if dupliate. Thanks

• Is there a .def file equivalent on Linux for controlling exported function names in a shared library

  - by morpheous

  I am building a shared library on Ubuntu 9.10. I want to export only a subset of my functions from the library. On the Windows platform, this would be done using a module definition (.def) file which would contain a list of the external and internal names of the functions exported from the library. I have the following questions: How can I restrict the exported functions of a shared library to those I want (i.e. a .def file equivalent) Using .def files as an example, you can give a function an external name that is different from its internal name (useful for prevent name collisions and also redecorating mangled names etc) On windows I can use the EXPORT command (IIRC) to check the list of exported functions and addresses, what is the equivalent way to do this on Linux?

• Check for Existence of a Result in Linq-to-xml

  - by NateD

  I'm using Linq-to-XML to do a simple "is this user registered" check (no security here, just making a list of registered users for a desktop app). How do I handle the result from a query like this: var people = from person in currentDoc.Descendants("Users") where (string)person.Element("User") == searchBox.Text select person; I understand the most common way to use the result would be something like foreach (var line in people){ //do something here } but what do you do if person comes back empty, which is what would happen if the person isn't registered? I've looked around on this site and on MSDN and haven't found a really clear answer yet. Extra credit: Give a good explanation of what people contains.

• Xcode, Dev Docs Search Field Loosing Focus?

  - by fuzzygoat

  I am having a strange issue with the developer documentation (which i have only noticed after installing Xcode 3.2.3). My problem is that as you type in the search field (upper right) it looses focus and immediately starts looking for the first few letters you type. For example if you looking for "NSObject" you start typing "NSO" and as you type the field looses focus the last 5 characters "bject" just give beeps as you need to reselect the field to type extra characters. Has anyone else come across this or know what the problem might be? cheers Gary.

• How small is *too small* for an opensource project?

  - by Adam Lewis

  I have a fair number of smaller projects / libraries that I have been using over the past 2 years. I am thinking about moving them to Google Code to make it easier to share with co-workers and easier to import them into new projects on my own environments. The are things like a simple FSMs, CAN (Controller Area Network) drivers, and GPIB drivers. Most of them are small (less than 500 lines), so it makes me wonder are these types of things too small for a stand alone open-source project? Note that I would like to make it opensource because it does not give me, or my company, any real advantage.

• Deserialization on client side in Domain Service

  - by ankit

  I have 2 classes: Person and Contact. Person class has a property named ContactNumber which returns the Contact type, and this property is marked as a DataMember for serialization. I have marked Contact type as a DataContract. On the client side I am able to get the values, but when I try to insert a value and then do submit, I get the following exception: Failed to deserialize change-set. Failed to convert value of type 'Dictionary`2' to type 'Contact' Stack Trace is: at System.Web.Ria.DataServiceSubmitRequest.GetChangeSet(DomainService domainService) at System.Web.Ria.DataServiceSubmitRequest.Invoke(DomainService domainService) at System.Web.Ria.DataService.System.Web.IHttpHandler.ProcessRequest(HttpContext context) Can anyone give me the solution ?

• What is the best tool to achieve this API design?

  - by Jose Fernandez

  Our web app offers a service that allows a "Publisher" to create a website (we give them a CMS system) that is ready to provide this service to "Members" (think Shopify). We have some possible clients that wish to become "Publishers" but they already have existing websites (vbulletin, word press blog, etc) with their own user base. We wish to develop an API that would allow these "Publishers" to keep using their own websites, and embed our services into them. Our main business requirement is that once "Members" are logged into the "Publishers" existing system, they should be able to also access our website without having to log-in again OR have to create another account there. The process should be seamless to the "Member" and "Publishers" should not have to sync their user base with our system. We also want to use an existing API authentication/authorization system instead of creating our own (OAuth, OpenID, etc) What would be the best way to use OAuth to achieve this sigle-sign on design? If OAuth is not the best tool, is there any other one out there that fits our requirements?

• Reusing MSBuild targets for different build types

  - by Zbigniew Kawalec

  I have got a problem with reusing the same MSBuild targets for different build types on TFS. Let me describe the situation. I have got two build types (CI - for continuous integration and RC - for release candidate). So I have got two build types defined in the TFS. Their *.proj files are under: - $/Repository/TeamBuildTypes/CI - $/Repository/TeamBuildTypes/RC Also, I have got some common targets, like: ChnageVersion.taget, Deploy.tagert, etc. and I import them in the main *.proj file. Unfortunaltely, I have to keep two copies of them, one in each build type. I've been struggling to have only one copy of the common targets somewhere, but I give up. I can't do it, because when the build starts on a build agent, the build files are downloaded from: $/Repository/TeamBuildTypes/CI only. How can I make the build agent / TFS / whatever to download also $/Repository/TeamBuildTypes/Common for example?

• Explanation of contribute_to_class

  - by anon.

  I'm attempted to extend code, and have come across an issue, I don't understand a line of code. I know the outcome of it - but I don't understand how it happens and am naturally enough scared to change it. The line of code I've come across is this: MyGenericRelation().contribute_to_class(model, 'field_name') The result of this code is a field with 'field_name' is added to the 'model' and from what I gather the objects inside the field are a list of type X (part of MyGenericRelation). I'm wondering if anyone can explain how this works. As in, why do I get a list of X objects attached to 'field_name' and if does it have to be generic relations prior to contribute_to_class or would using an actual model type, say 'Y' just give me a list of Y's. To be honest, I am more interested in the affect and functionality of the contribute_to_class method.

• what would be the c# equivalent of this code snippet?

  I don't really understand Perl, so I was wondering if someone could give me a hint about what it is this code is asking of STDIN, and how to say this in C#. Thanks. $TMPFILE = "xxx.tmp"; if (! -f STDIN) { open TMPFILE, "> $TMPFILE" or die "Couldn't open `$TMPFILE' for writing: $!; aborting"; print TMPFILE while <STDIN>; close TMPFILE; open STDIN, "< $TMPFILE" or die "Couldn't open `$TMPFILE' for reading: $!; aborting"; unlink $TMPFILE; }

• Why does Perl's Crypt::SSLeay timeout on Intel Mac OS X machines?

  - by Joe

  A have a Perl cron job that recently started having its HTTPS connections start failing with an error of "500 SSL read timeout". I've tracked that the error is being thrown as part of an alarm in Crypt::SSLeay, but I don't know if this is simply something taking too long to respond. So far, I've adjusted the timeout from the default 30 seconds to 10 minutes and it still times out. I've moved the script to other machines, and those on Intel Mac OS X systems all time out, while those under Linux, or on PPC Mac OS X systems run fine, so I don't think it's changes on the network or remote server. When the process started having problems does not coincide with any software updates or reboots on the machine, and I've contacted the server I'm connecting to, and everyone claims that they haven't changed anything. Does anyone have recommendations on trying to debug HTTPS, or have you ever seen this behavior and give recommendations on something I might've overlooked at that could've caused this problem?

• NHibernate - EventListener for SaveOrUpdateCopy

  - by t-kehl

  Hi. I do Update with SaveOrUpdateCopy(). Now, I have attached an event for this: this.EventListeners.SaveOrUpdateCopyEventListeners = new IMergeEventListener[] { new AuditableSaveOrUpdateCopyEventListener() }; In the AuditableSaveOrUpdateCopyEventListener, I have inherited from DefaultSaveOrUpdateCopyEventListener and overriden OnMerge(): public class AuditableSaveOrUpdateCopyEventListener : DefaultSaveOrUpdateCopyEventListener { public override void OnMerge(MergeEvent evt) { this.AddAuditableData(evt); base.OnMerge(evt); } public override void OnMerge(MergeEvent evt, System.Collections.IDictionary copyCache) { this.AddAuditableData(evt); base.OnMerge(evt, copyCache); } private void AddAuditableData(MergeEvent evt) { var entity = evt.Original as AuditableEntityBase; if (entity != null) { ... } } } But when I now change properties in entity, they will not be saved to the database. Can someone give me a tip, how I can add my auditable-data for SaveOrUpdateCopy? Thank you. Best Regards, Thomas

• Why does Java not have any destructor like C++?

  - by Abhishek Jain

  Java has its own garbage collection implementation so it does not require any destructor like C++ . This makes Java developer lazy in implementing memory management. And Garbage Collection is very expensive. Still we can have destructor along with garbage collector where developer can free resources and which can save garbage collector's work. This might improves the performance of application. Why does Java not provide any destructor kind of mechanism? Developer does not have control over GC but he/she can control or create object. Then why not give them ability to destruct the objects?
