• OutOfMemoryException - out of ideas II

  - by Captain Comic

  Hello, This question is related to my previous question. The storyline: I have an application which consumes a lot of memory if you look at task manager VMSize. I am trying to find out what consumes this amount of memory. You see in the picture below that VM size is 2,46 GB Ok now I am looking at .net performance counters Committed and reserved bytes add up to only 1,2 GB Now lets look at windb sos debugging. Let's run eeheap -gc command The heap size used by GC is only 340 MB. Where is the rest of used memory? I need to discover why WM size in TaskManager is 2.4 GB

• Associate mount points with local disks in VBscript / WMI

  - by Mark Unwin

  I have a VBscript that outputs various config items about a system. Both hardware and software. I can output disks and their associated partitions. I can output mount points. I do not seem to be able to associate a mount point with a local disk (where it actually is a local disk). I need to be able to do this using VBscript, so as to fit in with the rest of the ~2000 lines of code. I do NOT want to run some other program graphically. I know the disk manager service can show me (My Computer - Manage - Disk Management), but this is not what I need. I need to be able to do this remotely via VBscript. I am open to running an .exe from the VBscript and piping the output back into VBscript and massaging it from there. Any idea's ? Thanks in advance.

• How do I copy the layout from a header of a JTabbedPane onto a JPanel?

  - by Snail

  I have created a "CollapsingPanel"class/sort of a JTabbedPane (code skeleton can be found at http://www.coderanch.com/t/341737/Swing-AWT-SWT-JFace/java/Expand-Collapse-Panels). It is in other words a lot of headers which you click on to show a hidden Panel. At the moment these header-panels are a rectangular box with a LineBorder around them. That is ugly! I'm wondering if there is a way to copy the layout that the JTabbedPane uses for its headers/titles (which is inhierted from Look&Feel I assume) and use it on my JPanel-based headers? So that my headers get a smooth look which is in line with the rest of the program (based on Look&Feel!) instead of looking like alien flat blocks. Illustrated below with the headers nicely circled in green ;) I want to apply the header-look from 2nd picture over the red header JPanel in picture 1: Picture 1: hxxp://img7.imageshack.us/img7/2319/34158982.png - change to http, I got <10 rep :( Pictrue 2: hxxp://img46.imageshack.us/img46/2572/jtabpane.png

• Infragistics WebScheduleInfo Sample code

  - by Woodmark

  I am working with Infragistics35.WebUI.WebSchedule.v8.2. I am not seeing any good documentation on this on the Infragistics Web site. Does anyone have any sample code I could see? I am trying to create a week view of the calendar. One that "Admins" can edit and the rest of the users can only view. I would love to have a different dblclick event fire based on role, so that a read only version of the activity would show for non admins. Is that possible? I'm just using an access db on the site in the App_Data directory. I really just needed (I thought) an out of the box solution. Cheers.

• Is it possible to get Cufon to work on a button?

  - by Tom Harvey

  So right now I'm bashing my head - at the moment we use an element for a button to give it our own custom font, fine - this works, but as we're using Cufon on the rest of the site, we're wondering if it's possible to get Cufon working on a button. So far I've changed the button to an and using standard css styles on an 'input' or 'input[type="submit"]' element work fine - but I've tried both of these in cufon to no avail. This is a button - so as Cufon generates images, this should work, but maybe I'm doing it wrong - can anyone help?

• naming conventions for buttons in user interface

  - by Samuel

  User interface for web applications in general contain various buttons for performing CRUD operations. What would be the suggested naming convention for button labels while performing the following actions.. User creation (Add User... or Add User or Add user) Event creation (Add Event... or Add Event or Add event) View users button (List All Users or List All users or List all users ) Most of the sites seem to contain the last option (e.g. Add user) where the first alphabet in the word is capitalized and rest all are lower case). What would be a better practice here?

• How to enable HTTP response caching in Spring Boot

  - by Samuli Kärkkäinen

  I have implemented a REST server using Spring Boot 1.0.2. I'm having trouble preventing Spring from setting HTTP headers that disable HTTP caching. My controller is as following: @Controller public class MyRestController { @RequestMapping(value = "/someUrl", method = RequestMethod.GET) public @ResponseBody ResponseEntity<String> myMethod( HttpServletResponse httpResponse) throws SQLException { return new ResponseEntity<String>("{}", HttpStatus.OK); } } All HTTP responses contain the following headers: Cache-Control: no-cache, no-store, max-age=0, must-revalidate Expires: 0 Pragma: no-cache I've tried the following to remove or change those headers: Call setCacheSeconds(-1) in the controller. Call httpResponse.setHeader("Cache-Control", "max-age=123") in the controller. Define @Bean that returns WebContentInterceptor for which I've called setCacheSeconds(-1). Set property spring.resources.cache-period to -1 or a positive value in application.properties. None of the above have had any effect. How do I disable or change these headers for all or individual requests in Spring Boot?

• iPhone Feedback Service with PHP

  - by Anish

  HI All, Has anybody been able to extract the device tokens from the binary data that iPhone APNS feedback service returns using PHP? I am looking for something similar to what is been implementented using python here http://www.google.com/codesearch/p?hl=en&sa=N&cd=2&ct=rc#m5eOMDWiKUs/APNSWrapper/%5F%5Finit%5F%5F.py&q=feedback.push.apple.com As per the Apple documentation, I know that the first 4 bytes are timestamp, next 2 bytes is the length of the token and rest of the bytes are the actual token in binary format. (http://developer.apple.com/IPhone/library/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CommunicatingWIthAPS/CommunicatingWIthAPS.html#//apple%5Fref/doc/uid/TP40008194-CH101-SW3) I am successfully able to extract the timestamp from the data feedback service returns, but the device token that I get after i convert to hexadecimal using the PHP's built in method bin2hex() is actually different than original device token. I am doing something silly in the conversion. Can anybody help me out if they have already implemented APNS feedback service using PHP? TIA, -Anish

• Career advice: I am best at what I hate most

  - by flybywire

  I think my career has entered a vicious circle which I would like to exit: I am best at what I hate most. And because I am good at that, I always receive that kind of assignments, and I do them as expected or even better. Which makes me more of an expert and brings me more similar tasks. My "expertise" is what (I think) every programmer hates: legacy systems. I can very quickly learn systems, and modify them, migrate them, extract web services from them whatever (without breaking them). Never to develop more functionality or to solve interesting or original problems. Just have that work with Java 1.4, or convert it into a rest-full service or support oracle too. I feel (and I am told) that I am highly regarded and very helpful to my company. But I hate what I do. What would you do in my place?

• .NET Framework 4 Client Profile vs .NET Framework 3.5 Client Profile

  - by Janusz

  Currently I am targeting .NET Framework 3.5 Client profile. Under certain conditions (when .NET 1.x or 2.x is installed) the client profile is not installed and instead full version of .NET Framework 3.5. is installed. This limitation has been removed from .NET 4.0 profile - therefore its a nice improvement that significantly reduces download size on certain PCs. However, if I target application to .NET 4.0 then all the clients will have to download new framework. I think ideal scenario would be to target .NET 3.5 profile but point installer to .NET 4.0 client profile. This way PCs with 3.5 installed (65% from our tests at the moment) would be fine and the rest would install .NET 4.0. Is my thinking correct or its not feasible? Will .NET 3.5 profile application run with only .NET 4.0 profile installed? Thank you

• publish XML using WCF

  - by khalil

  Hi, I want to publish some data as XML from a SQL Server database using a WCF service to a location on our content delivery network. (www.somelocation-on-cdn/myxml.xml) This data which is published as XML will have to be updated at an interval of time. I was thinking of writing a WCF service to return the data required, create a RSS reader to update / write the XML file to a location on the content delivery network. Is this approach correct? Can I use WCF REST instead of WCF SOAP As a further enhancement I want to be to use this WCF Service to make cross domain calls using JSONP from our website Thanks

• SharePoint Workflow: how to update the item without triggering the workflow again

  - by Philipp Schmid

  I have a SharePoint workflow which is running whenever the item changes. The workflow communicates with an external REST service. If the service returns a string, I want to update one of the field values with that string. Unfortunately, this update will trigger another instance of the workflow for this item once the current workflow terminates. I end up with an infinite loop! How I can prevent this from happening? SPListItem has Update(), UpdateOverwriteVersion(), and SystemUpdate() methods but none of them seem to prevent subsequent workflows from being triggered. I could inspect the last modified timestamp of the item and terminate the workflow if the last update happened within a certain timespan, but I am looking for a more robust solution.

• PLINQ delayed execution

  - by tbischel

  I'm trying to understand how parallelism might work using PLINQ, given delayed execution. Here is a simple example. string[] words = { "believe", "receipt", "relief", "field" }; bool result = words.AsParallel().Any(w => w.Contains("ei")); With LINQ, I would expect the execution to reach the "receipt" value and return true, without executing the query for rest of the values. If we do this in parallel, the evaluation of "relief" may have began before the result of "receipt" has returned. But once the query knows that "receipt" will cause a true result, will the other threads yield immediately? In my case, this is important because the "any" test may be very expensive, and I would want to free up the processors for execution of other tasks.

• Neural Network Output Grouping 0.5?

  - by Mike

  I tried to write a Neural Network system, but even running through simple AND/OR/NOR type problems, the outputs seem to group around 0.5 (for a bias of -1) and 0.7 (for a bias of 1). It doesn't look exactly "wrong"... The 1,1 in the AND pattern does seem higher than the rest and the 0,0 in the OR looks lower, but they are still all grouped so it's debatable. I was wondering a) if there's some obvious mistake I've made or b) if there's any advice for debugging Neural Nets... seeing as you can't always track back exactly where an answer came from... Thanks! Mike

• manipulate objects outside svg with javascript-function inside the svg

  - by Christian Benke

  Hello! I'm embedding a svg-graphic on my website and i'd like to manipulate the rest of the website with javascript-commands which are in the svg - though i'm not sure if this is possible. Let me elaborate: I've got a worldmap in svg, i want to click on a country and this click should run an ajax-call and load relevant information of this country into a div in the html site where the svg is embedded. "onclick="location.href='xxx'"" redirects to the respective site which is fine, but i'd prefer to run a js-function that fetches the site with ajax - but running a javascript-function in the svg only seems to work for functions and elements defined in the svg, not outside of it. Is it basically possible to manipulate anything outside the svg through a js-function in the svg? How? Regards Christian

• ergonomics: what's better; trackball, ergonomic mouse or some other pointing device (a-la touchscree

  - by mauriciopastrana

  So I bit into the hype and recently purchased an apple wireless keyboard and that evil bar-of-soap thing apple makes for a mouse. Couple of hundred dollars later and this is where I begin to worry about RSI. Go figure. Don't get me wrong, this apple mouse is genius and looks pretty as hell, but my right wrist feels tired after a full day's worth of work, so i'm thinking of switching. Anyone out there use a trackball? is this worse? should I get a super-ergonomic mouse instead? I've seen mouse-trackball combos but am not sold, they still elicit the same end-finger behaviour detrimental for RSI, right? I also have a wrist-rest mousepad, but couldn't find one suitable for my keyboard. I've even considered having a small touchscreen where the mousepad should go, no mouse (or alternatively, a usb trackpad). Just looking for ideas, is the trackball better than the mouse? /mp

• Facebook Canvas iFrame App - Authorizing users with new OAuth protocol

  - by Rick

  Hi, I'm developing a new Facebook Canvas application within an iFrame and trying to authorize users. The new OAuth api recommends I do a redirect to the following to authorize a user in my app: https://graph.facebook.com/oauth/authorize? client_id=...& redirect_uri=http://www.example.com/oauth_redirect However this produces a weird problem where a full Facebook page requesting permissions from the user is rendered within the iFrame itself (i.e. facebook within Facebook). Does anyone know how to solve this with the new OAuth API as I don't want to start using old REST API methods. Thanks, Rick

• problem with hand tracking, opencv

  - by JP Talusan

  I am currently creating an opencv program that identifies a hand in an image and then gets the contour of the hand only, in order for us to get the center (x,y)m in pixels, of the hand. The problem is that whenever the image or video includes an arm or a face, we can't split or separate the hand from the contours of the arm or the face. We are currently using an HSV flesh colored histogram to get the contours of the hand. is there a way to separate them, i just need the hand. also if the picture includes only a hand and some part of the arm. How can we isolate the palm itself from the rest of the picture. all we need is a clear center of the palm. thanks in advanced.

• UITableView like Contact App

  - by Matthias

  Hi, I try to create an UITableView similar to the Standard Contact App, when selecting a contact (i.e. grouped style). But how do I get some controls at the top or at the bottom of the cells, which scroll with the rest? In the Contact App you have at the top the picture together with the name and at the bottom three buttons. Are these just special customized Cells? Or can you have controls directly there? Thanks for your help! Regards Matthias

• How can I implement an abstract singleton class in Java?

  - by Simon

  Here is my sample abstract singleton class: public abstract class A { protected static A instance; public static A getInstance() { return instance; } //...rest of my abstract methods... } And here is the concrete implementation: public class B extends A { private B() { } static { instance = new B(); } //...implementations of my abstract methods... } Unfortunately I can't get the static code in class B to execute, so the instance variable never gets set. I have tried this: Class c = B.class; A.getInstance() - returns null; and this ClassLoader.getSystemClassLoader().loadClass("B"); A.getInstance() - return null; Running both these in the eclipse debugger the static code never gets executed. The only way I could find to get the static code executed is to change the accessibility on B's constructor to public, and to call it. I'm using sun-java6-jre on Ubuntu 32bit to run these tests.

• How to run batched WCF service calls in Silverlight BackgroundWorker

  - by Simon

  Is there any existing plumbing to run WCF calls in batches in a BackgroundWorker? Obviously since all Silverlight WCF calls are async - if I run them all in a backgroundworker they will all return instantly. I just don't want to implement a nasty hack if theres a nice way to run service calls and collect the results. Doesnt matter what order they are done in All operations are independent I'd like to have no more than 5 items running at once Edit: i've also noticed (when using Fiddler) that no more than about 7 calls are able to be sent at any one time. Even when running out-of-browser this limit applies. Is this due to my default browser settings - or configurable also. obviously its a poor man's solution (and not suitable for what i want) but something I'll probably need to take account of to make sure the rest of my app remains responsive if i'm running this as a background task and don't want it using up all my connections.
