• Out of Memory - web applications

  - by Walter White

  Hi all, I am trying to figure out why Jetty 6.1.22 is running out of memory on my laptop. I have 2 web applications running JBoss Seam, Hibernate (with EHCache), and separate Quartz scheduler instances. With little load, the server dies throwing OutOfMemory. What can I look for? Would you think that I am not properly closing handles for input streams or files? I tried profiling my application with Netbeans, but it works off and on. Usually, it ends up locking up even though it doesn't use that much CPU or memory. Walter

• Base class for windows service

  - by user187020

  My new project has a design in which there are number windows services for performing different tasks. I have been given a task to create base class from which all of the windows service will inherit. This base class will perform common functions like creating instances of other windows services by iterating through the config file (may be like Activator.CreateInstance), do event logging on onStart, onStop etc. and may contain some more functionality. Before I start developing stuff, wondering if there is any pattern already in place or someone has good understanding of how to implement this kind of functionality. Any help appreciated.

• Creating an excel macro to sum lines with duplicate values

  - by john

  I need a macro to look at the list of data below, provide a number of instances it appears and sum the value of each of them. I know a pivot table or series of forumlas could work but i'm doing this for a coworker and it has to be a 'one click here' kinda deal. The data is as follows. A B Smith 200.00 Dean 100.00 Smith 100.00 Smith 50.00 Wilson 25.00 Dean 25.00 Barry 100.00 The end result would look like this Smith 3 350.00 Dean 2 125.00 Wilson 1 25.00 Barry 1 100.00 Thanks in advance for any help you can offer!

• JW Player: cross-browser "display:none" player behavior

  - by two7s_clash

  Is there a simple, upfront method to have FF and IE treat hidden JW Players the same? I am placing different instances of the player dynamically in jQuery generated tabs. In effect, switching tabs hides the parent div of each player. In FireFox, the tab switch and accompanying "display" change stops the player. This doesn't happen in IE. I would like it to. What is the easiest way to have both browsers act the same? I am hoping for a CSS/HTML solution, either thorough the way the players are embedded or a style rule Otherwise I suppose I will need to add an item listener that compares the currently selected tab id to currently active players... but I'd rather not go that route. Thanks for your tips! EDIT: So, I'd rather be able to change the player CSS or markup on tab change than send stop events to all the players but the player in the currently active tab.

• How to determine whether a dependency object implements a given dependency property (C# / WPF)

  - by Tim Coulter

  I am working with the classes in the System.Windows.Documents namespace, trying to write some generic code that will conditionally set the value of certain dependency properties, depending on whether these properties exist on a given class. For example, the following method assigns an arbitrary value to the Padding property of the passed FrameworkContentElement: void SetElementPadding(FrameworkContentElement element) { element.SetValue(Block.PaddingProperty, new Thickness(155d)); } However, not all concrete implementations of FrameworkContentElement have a Padding property (Paragraph does but Span does not) so I would expect the property assignment to succeed for types that implement this property and to be silently ignored for types that do not. But it seems that the above property assignment succeeds for instances of all derivatives of FrameworkContentElement, regardless of whether they implement the Padding property. I make this assumption because I have always been able to read back the assigned value. I assume there is some flaw in the way I am assigning property values. What should I do to ensure that a given dependency property assignment is ignored by classes that do not implement that property? Many thanks for your advice. Tim

• Performance of DrawingVisual vs Canvas.OnRender for lots of constantly changing shapes

  - by romkyns

  I'm working on a game-like app which has up to a thousand shapes (ellipses and lines) that constantly change at 60fps. Having read an excellent article on rendering many moving shapes, I implemented this using a custom Canvas descendant that overrides OnRender to do the drawing via a DrawingContext. The performance is quite reasonable, although the CPU usage stays high. However, the article suggests that the most efficient approach for constantly moving shapes is to use lots of DrawingVisual instances instead of OnRender. Unfortunately though it doesn't explain why that should be faster for this scenario. Changing the implementation in this way is not a small effort, so I'd like to understand the reasons and whether they are applicable to me before deciding to make the switch. Why could the DrawingVisual approach result in lower CPU usage than the OnRender approach in this scenario?

• Reference methods defined in one JScript file from another JScript

  - by Thomas Svensen

  I am writing some server-side scripts using jscript and WSH. The scripts are getting quite long, and some common functions and variables would fit better in a general library script which I included in my various script instances. But, I cannot find a way reference one JScript file from another. For a moment, I though reading the file contents and passing it to "eval()" could work. But, as it says on MSDN: "Note that new variables or types defined in the eval statement are not visible to the enclosing program." (http://msdn.microsoft.com/en-us/library/b51a45x6.aspx) Is there any way to include/refence a JScript from another one?

• How to Open a Remote Text File using Server.MapPath in ASP.Net?

  - by NJTechGuy

  This is what I have right now for a file residing on the same server and it works. Dim FILENAME as String = Server.MapPath("Output.txt") Dim objStreamWriter as StreamWriter objStreamWriter = File.CreateText(FILENAME) dr = myCommand.ExecuteReader() While dr.Read() objStreamWriter.WriteLine("{0}|{1}|{2:yyyy-MM-dd}|{3:yyyy-MM-dd}", dr(0), dr(1), dr(2), dr(3)) End While objStreamWriter.Close() I was planning on FTPing the file to another server once done but is there a way to do it on a remote server? i.e create a text file on a remote server and write to it? Did not find any instances of that usage. How to use ServerXMLHTTP to replace Server.MapPath in this instance? Thank you so much for your time.

• Eclipse warning: "<methodName> has non-API return type <parameterizedType>"

  - by Tenner

  My co-worker and I have come across this warning message a couple times recently. For the below code: package com.mycompany.product.data; import com.mycompany.product.dao.GenericDAO; public abstract class EntityBean { public abstract GenericDAO<Object, Long> getDAO(); // ^^^^^^ <-- WARNING OCCURS HERE } the warning appears in the listed spot as EntityBean.getDAO() has non-API return type GenericDAO<T, ID> A Google search for "has non-API return type" only shows instances where this message appears in problem lists. I.e., there's no public explanation for it. What does this mean? We can create a usage problem filter in Eclipse to make the message go away, but we don't want to do this if our usage is a legitimate problem. Thanks!

• jQuery-ui problem with modal dialog from ajax

  - by Intra

  Hi I have following setup index.html with <div id="container"</div using anchor method I load different html content into this container. My content contains div for modal dialog "dialog-form" and I initialise it with the custom function from the javascript included in index.html on successful ajax load using callback $.get("callback.php",query, function(data){ $("#container").html(data); initPos(); // here we run javascript to initialise modal dialog }); Everything is ok until user click other menu (we load different content) and after that again clicks menu with this modal dialog, so page loads again, we call script again (everything is ok yet), dialog opens, information from the dialog is submitted to server and on sucessful sumbit I want to close the dialog with ('#dialog-form').dialog('close');it worked first time, but no longer works because we initialised this dialog twice and using Firebug I can see two different instances of modal dialog with the same name. So, what is the right way to do the thing? Is there any way to close multiple dialogs with the same name or maybe we can kill all closed modal dialogs when user clicks different menu?

• Merge entries in CakePHP

  - by Andrea

  Let's say I have a Model, for example User, and I want to merge two instances of this Model, say merge User2 into User1. Explicitly this is what I mean: If a field is already filled in User1, it should remain the same If a field is missing in User1 but is present in User2, it should be copied If SomeModel BelongsTo User, every instance of SomeModel pointing to User2 should be modified to point to User1 Same if SomeModel HasAndBelongsToMany User If SomeModel HasMany User, and SomeModel1 Has User2 but no other instance Has User1, it should be modified so that SomeModel1 has User1 instead If SomeModel HasMany User, SomeModel1 Has User1 and SomeModel2 Has User2... well, I'm not sure here, I guess the only solution is to discard SomeModel2, since User1 can BelongTo only one SomeModel. Finally User2 should be removed. Is there a way to automate this? Maybe a Behaviour? If not, I may consider creating it, since I will need it a lot.

• CFNetwork / NSURLConnection leak

  - by JK

  Running instruments on the device, I intermittently incur a memory leak of exactly 3.5 KB in CFNetwork, the responsible frame being "HostLookup_Master::HostLookup...." I have read a number of questions re this issue and have separately tried the following to fix the leak: Included the following in applicationDidFinishLaunching: NSURLCache *sharedCache = [[NSURLCache alloc] initWithMemoryCapacity:0 diskCapacity:0 diskPath:nil]; [NSURLCache setSharedURLCache:sharedCache]; [sharedCache release]; Specified in the urlrequest not to load from the local cache. None of the above worked. My class that instantiates the connections does not leak as its instances are released when data has been downloaded. I have verified this by confirming the the living objects of the class is 0 using Instruments. Any advice on addressing this leak would be greatly appreciated.

• How do you develop Visual Studio Add-Ins?

  - by devoured elysium

  I have a vague idea Visual Studio allows you to run a second sandboxed instance where the add-in is being in fact loaded. That'd allow you to debug your add-in code and such. Is this effectively possible? How would I go about doing that? I'm currently using a single instance of Visual Studio. I'm having the problem that as I load and run the add-in, it won't allow me to compile again until I restart that instance of Visual Studio as there seems to be no way to unload the add-in. Even using two instances of Visual Studio wouldn't really help in here. There must be an easier way, how do you guys do it? Thanks

• iPhone OS: Fetching a random entity instance using NSPredicate Nsfetchrequest and core data

  - by nickthedude

  Working on an app where I have a large collections of managed objects against which I want to fetch a few random instances. My question is, is there any way I can use NSPredicate and NSFetchRequest to return several objects at random. I saw that you could actually add a NSFetchRequest into the entity using the data modeler, any way to do the random fetch using this? Also what would be the best method for determining the "count" of a table so I can set the bounds of the random number generator. let me know if you need more details. Thanks! Nick

• Django IN query as a string result - invalid literal for int() with base 10

  - by bmelton

  Trying to query a 'Favorites' model to get a list of items a user has favorited, and then querying against a different model to get the objects back from that query to present to the template, but I'm getting an error: "invalid literal for int() with base 10" Looking over all of the other instances of that error, I couldn't find any in which the asker actually wanted to work with a comma separated list of integers, so I'm kind of at a loss. Model class Favorite(models.Model): # key should be the model name, id is the model.id, and user is the User object. key = models.CharField(max_length=255, unique=True) val = models.IntegerField(default=0) user = models.ForeignKey(User) class Admin: list_display = ('key', 'id', 'user') View def index(request): favorites = Favorite.objects.filter(key='blog', user=request.user.pk) values = "" for favorite in favorites: values += "%s," % favorite.val #values = "[%s]" % values blogs = Blog.objects.filter(pk__in=values) return render_to_response('favorite/index.html', { "favorites" : favorites, "blogs" : blogs, "values" : values, }, context_instance=RequestContext(request) ) enter code here

• Best practices for managing limited client licenses/login

  - by MicSim

  I have a multi-user software solution (containing different applications, i.e. EXEs) that should allow only a limited number of concurrent users. It's designed to run in an intranet. I dont have a really good, satisfactory solution to the problem of counting the client licenses yet. The key requirements are: Multiple instances (starts) of the same application (= process) should count as only one client licence Starting different applications of the software solution should also count as only one (the same) client licence Application crash should not lead to orphaned used licences The above should work also for Terminal Server environments (all clients same IP, but different install folders) I'm looking for estabilished patterns, solutions, tips for managing used client licenses. Specific hints for the above sitaution are also welcome.

• Marshal struct to unmanaged array

  - by Pedro

  Hi guys, I have a C# struct to represent a cartesian vector, something like this: public struct Vector { private double x; private double y; private double z; //Some properties/methods } Now I have an unmanaged C dll that I need to call with P/Invoke. Some methods expect a double[3] parameter. The unmanaged C signature is something like void Cross(double a[3], double b[3], double c[3]); Is there any way to set up a P/Invoke signature so I can pass instances of my Vector struct and marshal them transparently to unmanaged double[3]? I would also need bidirectional marshaling as the unmanaged function needs to write the output to the argument array, so I guess I would need to marshal as LpArray. Any ideas? Thanks Pedro

• Can't run os.system command in Django?

  - by danspants

  We have a Django app running on apache server (mod_python) on a windows machine which needs to call some r scripts. To do so it would be easiest to call r through os.system, however when django gets to the os.system command it freezes up. I've also tried subprocess with the same result. We have a possibly related problem in that Django can only access the file system of the machine it's on, all network drives appear to be invisible to it, which is VERY frustrating. Any ideas on both of these issues (I'm assuming it's the same limitation in both instances) would be most appreciated.

• Help me with a solution for what could be solutioned by virtual static fields... in FPC

  - by Gregory Smith

  Hi I'm doing an event manager in Freepascal Each event is an object type TEvent (=object), each kind of event must derive from this class. Events are differentiated by an integer identificator, assigned dynamically. The problem is that i want to retrieve the event id of an instance, and i can't do it well. All instances of a class(object) have a unique id = so it should be static field. All classes have a diferent id = so it should be virtual. Event ids are assignated in run time, and can change = so it can't be a simple method In sum, I can't put all this together. I'm looking for an elegant solution, i don't want to write a hardcoded table, actualizing it in every constructor... etc, i'd prefer something taking advantage of the polymorphism Can anyone help me with another technical or design solution? I remark I don't want to use class instead of object construct.(property doesn't work on objects? :(

• ASP.NET MVC Validation of ViewState MAC failed

  - by Kevin Pang

  After publishing a new build of my ASP.NET MVC web application, I often see this exception thrown when browsing to the site: System.Web.Mvc.HttpAntiForgeryException: A required anti-forgery token was not supplied or was invalid. --- System.Web.HttpException: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. --- System.Web.UI.ViewStateException: Invalid viewstate. This exception will continue to occur on each page I visit in my web application until I close out of Firefox. After reopening Firefox, the site works perfectly. Any idea what's going on? Additional notes: I am not using any ASP.NET web controls (there are no instances of runat="server" in my application) If I take out the <%= Html.AntiForgeryToken % from my pages, this problem seems to go away

• DDD - Validation of unique constraint

  - by W3Max

  In DDD you should never let your entities enter an invalid state. That being said, how do you handle the validation of a unique constraint? The creation of an entity is not a real problem. But let say you have an entity that must have a unique name and there is a thousand instances of this entity type - they are not in memory but stored in a database. Now let say you want to rename an instance. You can't just use a setter... the object could enter an invalid state - you have to validate against the database. How do you handle this scenario in a web environment?
