• WPF ListView.CurrentChanged too fast for binding

  - by matt

  My case: MVVM ListView+Details(custom UserControl) List bound to MV.Items (IsSynchronizedWithCurrent=true) Details bound to MV.Items.Current MV.Items.Count == 100 about 0.2sec to read details (lazy mode) When I hold the down arrow on the list, very strange things happen: list items order change current changes in the random order CPU usage drastically increments and eventually all hangs. I've read some post that one should start the timer or run handler in the background, but I am not able to do that, since all the binding WPF does for me. Is there some way to instruct the binding in my DetailsControl, to wait a while before accepting CurrentItem? Or should I just resign from the clean solution and write custom code in my MV to handle that?

• HSQLDB Constraint Violation & SQL Query Log for an HSQLDB in-memory setup

  - by shipmaster

  We have a setup where we are using an embedded HSQLDB for backing Hibernate/JPA unit tests in java, and we are using the in-memory database mode since we simply want the database thrown away after the test run. My problem is that one of the tests is failing due to a constraint violation and HSQLDB lists the column as SYS_CT_286, and the query that appears in the log is the prepared statement where I cant see what the actual parameter values are (they are replaced by '?'). My questions are: 1- Is there a way in which I can see the actual SQL being executed? (like the mysql query log for example?). 2- What exactly is SYS_CT_286? it is not one of my columns, is it a generated column? is there something obvious that may be wrong with it? Thanks.

• How can I find out which version of emacs introduced a function?

  - by Chris R

  I want to write a .emacs that uses as much of the mainline emacs functionality as possible, falling back gracefully when run under previous versions. I've found through trial and error some functions that didn't exist, for example, in emacs 22 but now do in emacs 23 on the rare occasion that I've ended up running my dotfiles under emacs 22. However, I'd like to take a more proactive approach to this, and have subsets of my dotfiles that only take effect when version = <some-threshold> (for example). The function I'm focusing on right now is scroll-bar-mode but I'd like a general solution. I have not seen a consistent source for this info; I've checked the gnu.org online docs, the function code itself, and so far nothing. How can I determine this, without keeping every version of emacs I want to support kicking around?

• First Call to a Controller, Constant is defined, Second call, "uninitialized constant Oauth"?

  - by viatropos

  I am trying to get the OAuth gem to work with Rails 3 and I'm running into this weird problem... (independent of the gem, I think I've run into this once before) I have a controller called "OauthTestController", and a model called "ConsumerToken". The model looks like this. require 'oauth/models/consumers/token' class ConsumerToken < ActiveRecord::Base include Oauth::Models::Consumers::Token end When I go to "/oauth_test/twitter", it loads the Oauth::Models::Consumers::Token module and I'm able to connect to twitter no problem. But the second time I try it (just refresh the /oauth_test/twitter url), it gives me this error: NameError (uninitialized constant Oauth): app/models/consumer_token.rb:4 app/models/twitter_token.rb:2 app/controllers/oauth_test_controller.rb:66:in `load_consumer' Why is that? It has something to do with load paths or being in development mode maybe?

• NSTimer to fire while device is locked

  - by edie

  Hi, I'm currently creating an alarm. I use NSTimer to schedule my alarms. My problem is when the device was put into locked mode my NSTimer doesn't fire. I think that the NSTimer will not fire because my app goes to suspended state when it is lock. Can you help me find a solution to my problem? I've found some topics about UIBackgroundModes, but I don't know how it will help me. Thanks.. The problem in UILocalNotification is when the device was in silent, the sound will not be hear. My implementation was I'm using NSTimer to fire an alarm when the app is in foreground or device is locked but app currently running. When the applicationDidEnterBackground: is called I schedule the UILocalNotification as the alarm.

• Detecting incorrect key using AES/GCM in JAVA

  - by 4r1y4n

  I'm using AES to encrypt/decrypt some files in GCM mode using BouncyCastle. While I'm proving wrong key for decryption there is no exception. How should I check that the key is incorrect? my code is this: SecretKeySpec incorrectKey = new SecretKeySpec(keyBytes, "AES"); IvParameterSpec ivSpec = new IvParameterSpec(ivBytes); Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding", "BC"); byte[] block = new byte[1048576]; int i; cipher.init(Cipher.DECRYPT_MODE, incorrectKey, ivSpec); BufferedInputStream fis=new BufferedInputStream(new ProgressMonitorInputStream(null,"Decrypting ...",new FileInputStream("file.enc"))); BufferedOutputStream ro=new BufferedOutputStream(new FileOutputStream("file_org")); CipherOutputStream dcOut = new CipherOutputStream(ro, cipher); while ((i = fis.read(block)) != -1) { dcOut.write(block, 0, i); } dcOut.close(); fis.close(); thanks

• Recover backup copy of a ubuntu linux installation on a usb stick using dd

  - by Werner

  Hi, I installed Ubuntu 10.04 on a usb stick in persistent install mode. So I could boot the laptop or my desktop computer with the stick, at boot time. Once I needed the 8GB stick for another purposes so I thought about coyping it to my desktop doing from mac os x: dd if=/dev/disks3s of=/Users/jack/Desktop/usb_copy Now I am trying to do the opposite, after having used the stick, which was formatted to NTFS, just doing dd if=/Users/jack/Desktop/usb_copy of=/dev/disks3s but although I can see that almost of the files are there, I can not boot again. IT is also strange the the file permissions are kind of strange, something like _user What can I do ? Thanks

• Bitbanging a PIO on Coldfire/ucLinux

  - by G Forty

  Here's the problem: I need to program some hardware via 2 pins of the PIO (1 clock, 1 data). Timing constraints are tight - 10ms clock cycle time. All this, of course, whilst I maintain very high level services (CAN bus, TCP/IP). The downstream unit also ACKS by asserting a PIO pin, configured as an input, high. So this loop has to both read and write. I need to send 16 bits in the serial stream. Is there an established way to do this sort of thing or should I simply get the hardware guys to add a PIC or somesuch. I'd much prefer to avoid exotics like RTAI extensions at this stage. I did once see a reference to user-mode IO which implied a possible interrupt driven driver but lost track of it. Any pointers welcomed.

• Log4cxx sample program and steps to compile

  - by Jake

  Hi guys Hoping someone can help out.. I've been scouring the net for a simple how-to to get a good log4cxx program working, with steps on setting up the libraries, dependants, directives, library paths etc etc.. as of yet i've found a lot of valuable but disjointed information.. trying to pull it all together has been a bit of a nightmare, so i'm reaching out and wondering if any kind soul knows of, or could put together a simple how-to, to get a standard win32 console app running with either static or dynamically linked release mode log4cxx.. I have win32 binary releases of the libraries, and thanks to a very cool dude from "Must a blog have a name" I have a win32 project which can build log4cxx.. i just cant bloody use it :) It would be really helpful to me, and probably to others, to be able to refer to something like this and not 20 different pages, with different lists of libraries needed to download and install.. :) Here's hoping Thanks guys J

• Linux core dumps are too large!

  - by themoondothshine

  Hey guys, Recently I've been noticing an increase in the size of the core dumps generated by my application. Initially, they were just around 5MB in size and contained around 5 stack frames, and now I have core dumps of 2GBs and the information contained within them are no different from the smaller dumps. Is there any way I can control the size of core dumps generated? Shouldn't they be at least smaller than the application binary itself? Binaries are compiled in this way: Compiled in release mode with debug symbols (ie, -g compiler option in GCC). Debug symbols are copied onto a separate file and stripped from the binary. A GNU debug symbols link is added to the binary. At the beginning of the application, there's a call to setrlimit which sets the core limit to infinity -- Is this the problem?

• In Android Browser link does not always execute onClick causing focus instead

  - by Artem

  I am trying to program a very standard JS behavior for a link using an HREF onClick handler, and I am facing a strange problem caused by what I believe to be focus/touch mode behavior on Android. Sometimes when I click on the link, instead of executing the action, it simply becomes selected/focused, with either just a focus rectangle or even also with a filled focus rectangle (selected as opposed to just focused?). The pseudo-code right now is <a href="#" onClick="toggleDivBelowToShowHide(); return false;">go</a> I have tried doing something like: <a href="#" onTouchStart="toggleDivBelowToShowHide(); return false;">go</a> But I still get the same pesky problem some of the time.

When I click "Buy" button I pass all checks for internet availability, canMakePayments and call SKPayment *payment = [SKPayment paymentWithProductIdentifier:featureId]; [[SKPaymentQueue defaultQueue] addPayment:payment]; But all what I see is a pending view and after some minutes it failed in - (void) failedTransaction: (SKPaymentTransaction *)transaction { if (transaction.error.code != SKErrorPaymentCancelled) { NSLog(@"failedTransaction"); } [[MKStoreManager sharedManager] paymentCanceled]; [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; } Please advice in what direction I should go to figure out the problem and what else I should check. P.S. All related questions on SO were checked with no luck.

• /SUBSYSTEM:Windows program will not write to command line

  - by user144182

  I have a mixed mode C++-CLI program in Visual Studio 2005 that is set to use the /SUBSYSTEM:Windows. Generally speaking it is a graphical application that is launched from its shortcut or through the filetype registered to it. However, there is a rare occasion where a user will want to run it from the command line with arguments. I can access the arguments just fine, its when it comes to writing to the console, in response to the program being launched from the command line with arguments, where I don't see Console::WriteLine having any effect. What am I doing wrong?

• Getting "Object is read only" error when setting ClientCredentials in WCF

  - by Paul Mrozowski

  I have a proxy object generated by Visual Studio (client side) named ServerClient. I am attempting to set ClientCredentials.UserName.UserName/Password before opening up a new connection using this code: InstanceContext context = new InstanceContext(this); m_client = new ServerClient(context); m_client.ClientCredentials.UserName.UserName = "Sample"; As soon as the code hits the UserName line it fails with an "Object is read-only" error. I know this can happen if the connection is already open or faulted, but at this point I haven't called context.Open() yet. I have configured the Bindings (which uses netTcpBinding) to use Message as it's security mode, and MessageClientCredentialType is set to UserName. Any ideas?

• How to debug a GWT application running on OSGi?

  - by Jaime Soriano

  I'm developing a web UI using GWT. While working only with the widgets I could debug from Eclipse using the Firefox extension, but now that I'm integrating the UI with other OSGi bundles I cannot use this solution. For deploying the GWT application I create the .war and convert it to an OSGi bundle using BND. Then I launch the OSGi container with all the bundles using Pax Runner and Pax Web and the application works correctly, but when something fails in the generated javascript code I don't have any decent output error or debugging facility. Is there any way to launch the GWT application in "debug mode" from OSGi? Any other idea that could help in this scenario?

• Web Service in c# - "This web service is using http://tempuri.org/ as its default namespace."

  - by glenatron

  I've created a web service using Visual Studio ( 2005 - I know I'm old school ) and it all compiles fine but when it opens I get warned thus: This web service does not conform to WS-I Basic Profile v1.1. And furthermore: This web service is using http://tempuri.org/ as its default namespace. Which would be fine except my service begins thus: [WebService(Namespace = "http://totally-not-default-uri.com/servicename")] Searching the entire solution folder for "tempuri" returns nothing. I can't find it mentioned in any configuration page acessible from Visual Studio. And yet it's right there in the wsdl:definitions list for the xmlns:tns attribute on the web service descriptor page when I view it through the browser and as targetNamespace in the same tag. I'm viewing it using Visual Studio's "debug" mode with the built in server from that. Seems like something has got cached somewhere but I can't work out what and where- I've tried stopping and restarting the server, cleaning and rebuilding the service and going through the associated text config files with a text editor but no dice. Any idea what is going on?

• I have some questions about building an AIR app for use with a connected projector.

  - by knuckfubuck

  For an app I'm working on, I'd like to have a control panel window and a video output window to use for projecting video with an attached projector. I have built many Flash applications but this will be my first time using AIR so I have some questions. Is it possible to have two seperate windows as part of one AIR application? Can one of the windows (the video output) be in full-screen mode while the other window stays normal? How does AIR do with playing local video? Will there be crashes or choppy playback? Is there a better language option for what I'm trying to accomplish?

• Problem running ASP.NET MVC 2 website on IIS7

  - by Charlie

  I'm trying to deploy my ASP.NET MVC 2 website from VS2010 beta 2 to IIS7. The publish works fine but none of the routes work, so when I go to the URL http://localhost/myapp/Home/Index I get the error: HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. I'm deploying to a virtual directory which is using an app pool configured for the .NET 4 framework with managed pipeline mode set to integrated. Also, if I go Basic Settings-Test Connection, both tests pass. From what I understand, it should just work? I don't have any problems deploying Nerd Dinner from VS2008, that works fine.

• UIView Clipped By Statusbar until Autorotate

  - by TonyNeallon

  Hi There, Ive created a multiview application that uses multiple controllers to display and control views. The problem Im having is, when the simulator initially loads the view the header is partially covered by the bar at top of screen and the tool bar at the base is not touching the base of the screen. I used the Interface builder size attributes to control the view when the iphone rotates and it works perfectly. All smaps into place perfectly both in landscape and portrait mode AFTER a rotation but the problem is with the initial load before a rotation occurs. Your thoughts a much appreciated. Tony
