  • Can I get the stack traces of all threads in my c# app?

    - by Drew Shafer
    I'm debugging an apparent concurrency issue in a largish app that I hack on at work. The bug in question only manifests on certain lower-performance machines after running for many (12+) hours, and I have never reproduced it in the debugger. Because of this, my debugging tools are basically limited to analyzing log files. C# makes it easy to get the stack trace of the thread throwing the exception, but I'd like to additionally get the stack traces of every other thread currently executing in my AppDomain at the time the exception was thrown. Is this possible?

  • Coordinating the logging output from a web app installed in a SharePoint farm.

    - by Kelly French
    We are deploying web parts to SharePoint 2007 and would like to include logging (log4net). The ideal solution would be to use a database appender to avoid the problems with knowing which actual server is executing the web part. This questions has been helpful: http://stackoverflow.com/questions/219668/sharepoint-and-log4net. I've got log4net working in a stand-alone web app using Visual Studio dev server using the web.config for the log4net settings and a file appender for the output. I'd like to transition to SharePoint and still use the log file output so I can make sure it's all working first, then change the config around to log to a database. Is this going to be too much trouble? How have other developers added log4.net into their solutions for SharePoint?

  • (Vista) Discover what app is reserving a shortcut key?

    - by Eddie Parker
    My problem is this: I've always managed to map WIN+V to foobar2000's "Next song" keyboard shortcut. For some reason, on this new machine, I can't. I've done this before on Vista, so the only thing I can think of is that some other application is holding onto this shortcut key. When I try to assign the shortcut key in foobar2000, nothing registers. When I press it outside of foobar2000, nothing occurs either. I'm at a loss as to how to proceed. Are there any apps to see what hooks are being requested by what application? Or is there a better way of diagnosing this?

    - by acidzombie24
    I want to execute a cmd line tool to process data. It does not need to be blocking. I want it to be low priority. So i wrote the below Process app = new Process(); app.StartInfo.FileName = @"bin\convert.exe"; app.StartInfo.Arguments = TheArgs; app.PriorityClass = ProcessPriorityClass.BelowNormal; app.Start(); However i get a System.InvalidOperationException with the msg "No process is associated with this object." Why? how do i properly launch this app in low priority? PS: Without the line app.PriorityClass = ProcessPriorityClass.BelowNormal; the app runs fine.

  • keep only GUI when converting vb6 app to c#?

    - by Craig Johnston
    I have a large VB6 app which I want to convert to C#. The majority of the code in VB6 is quite badly written. I thought that a good strategy would be to keep the GUI design since it is adequate and would be a pain to recreate. But I would want to rewrite the code behind the GUI and the data layer. I could keep the GUI design by using one of the VB6 to .NET converters provided by Microsoft. Would this be a good strategy?

  • Looking for a recommendation on measuring a high availability app that is using a CDN.

    - by T Reddy
    I work for a Fortune 500 company that struggles with accurately measuring performance and availability for high availability applications (i.e., apps that are up 99.5% with 5 seconds page to page navigation). We factor in both scheduled and unscheduled downtime to determine this availability number. However, we recently added a CDN into the mix, which kind of complicates our metrics a bit. The CDN now handles about 75% of our traffic, while sending the remainder to our own servers. We attempt to measure what we call a "true user experience" (i.e., our testing scripts emulate a typical user clicking through the application.) These monitoring scripts sit outside of our network, which means we're hitting the CDN about 75% of the time. Management has decided that we take the worst case scenario to measure availability. So if our origin servers are having problems, but yet the CDN is serving content just fine, we still take a hit on availability. The same is true the other way around. My thought is that as long as the "user experience" is successful, we should not unnecessarily punish ourselves. After all, a CDN is there to improve performance and availability! I'm just wondering if anyone has any knowledge of how other Fortune 500 companies calculate their availability numbers? I look at apple.com, for instance, of a storefront that uses a CDN that never seems to be down (unless there is about to be a major product announcement.) It would be great to have some hard, factual data because I don't believe that we need to unnecessarily hurt ourselves on these metrics. We are making business decisions based on these numbers. I can say, however, given that these metrics are visible to management, issues get addressed and resolved pretty fast (read: we cut through the red-tape pretty quick.) Unfortunately, as a developer, I don't want management to think that the application is up or down because some external factor (i.e., CDN) is influencing the numbers. Thoughts? (I mistakenly posted this question on StackOverflow, sorry in advance for the cross-post)

  • 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?

  • Why are my CATransitions acting up?

    - by Regan
    I am using the following code to switch between views with CATransition. CATransition *applicationLoadViewIn = [CATransition animation]; [applicationLoadViewIn setDuration:20]; [applicationLoadViewIn setType:kCATransitionPush]; [applicationLoadViewIn setSubtype:kCATransitionFromTop]; [applicationLoadViewIn setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]]; ViewToSwitchTo *myviewcontroller = [[ViewToSwitchTo alloc] init]; [self.view.layer addAnimation:applicationLoadViewIn forKey:kCATransitionPush]; [self.view addSubview:myviewcontroller.view]; It functions mostly how I want it to. It pushes from the top like it should, however it for some reason acts strangely. First, the view I am switching to starts coming in from the bottom like it should, but for some reason, the view that I am switching FROM appears over the top of it with low opacity, so you see both of them. However, you also see the view that is coming in, shifted maybe 100 pixels upwards, on top of itself and the other view, once again with low opacity. Just before the halfway point of the the transition, everything works fine, you only see the view that is coming in and the view going out, doing what they should be doing. But slightly after the halfway point, the view I am switching to appears in its final destination, under the view I am switching from, and the view I am switching from has been reduced in opacity. What is going on here?

  • Can an app use the clipboard for its own purposes? (read: who owns the clipboard?)

    - by eran
    In PowerBuilder's IDE, the code autocomplete feature uses the clipboard to communicate the completed text to the code window. By doing so, it overrides whatever was stored on the clipboard before. So, if you had the winning numbers of the next lottary stored on your clipboard, and you used the autocomplete to turn m_goodfor into m_goodfornothing, you've just lost your only chance of ever getting rich, and you're left with nothing on your clipboard. Features like that are the reason I hate software. It looks like it was implemented by some intern that noone was looking after. However, there's also a chance I got all worked up for nothing, and making such use of the clipboard is absolutely legit. So, can an app use the clipboard for its own purposes? Who is considered the owner of the clipboard? (Bonus votes to whoever puts himself in place of the feature's programmer, and provides some reasoning for this being done on purpose, assuming the users would actually benefite from it)

  • Specify Search Path for .net assembly binding/Fusion in app.config?

    - by Michael Stum
    I have an application that depends on other .net assemblies. When I start the application, I get an error that an assembly or one of its dependencies cannot be loaded. I do not want to put the assemblies into the GAC or into the Directory of the application. Is there a way (app.config?) to tell .net to look into a given path when trying to load assemblies? I believe I can use assembly binding for a single assembly, but I'm looking for a wildcard solution to add a path to the "search paths"

  • How can I test ActiveRecord::RecordNotFound in my rails app?

    - by fursie
    Hi, I have this code in my controller and want to test this code line with a functional test. raise ActiveRecord::RecordNotFound if @post.nil? which assert method should I use? I use the built-in rails 2.3.5 test framework. I tried it with this code: test "should return 404 if page doesn't exist." do get :show, :url => ["nothing", "here"] assert_response :missing end but it doesn't work for me. Got this test output: test_should_return_404_if_page_doesn't_exist.(PageControllerTest): ActiveRecord::RecordNotFound: ActiveRecord::RecordNotFound app/controllers/page_controller.rb:7:in `show' /test/functional/page_controller_test.rb:21:in `test_should_return_404_if_page_doesn't_exist.'

  • What language/API to use for a standalone live-input audio visualizer app?

    - by knuckfubuck
    I develop with Actionscript and was glad to see that AIR 2.0 was going to give access to mic input data. I planned to use this to create a visualizer set to the tempo of the incoming live audio. After doing a few days of google research it seems unlikely that it will be possible to analyze the data of the mic input in Flash/AIR. If anyone has ideas on how I can achieve this in AIR please let me know. (I'm open to workarounds.) That being said, I don't want to give up on the idea so I'm interested in suggestions for other language/API to use. My requirements for the app are: Run on OSX Two windows - one that can go fullscreen while the other(controller GUI) stays put Able to access live mic input data I've done reading on FFT and understand what needs to be done on the sound side so no need to help with that.

  • MultiActionController no longer receiving requests?

    - by Stefan Kendall
    I was attempting to make changes to my controller, and all of a sudden, I no longer seem to receive any requests (404 when attempting to hit the servlet mapped URLs). I'm sure I've broken my web.xml or app-servlet.xml, but I just don't see where. I can access index.jsp from tomcat (http://IP/app/index.jsp), but I can't get my servlet mapping to work correctly.

  • register device at run time

    - by user177893
    In the App ID section of the Program Portal, locate the App ID you wish to use with the Apple Push Notification service. Only App IDs with a specific bundle ID can be used with the APNs. You cannot use a “wild-card” application ID. You must see “Available” under the Apple Push Notification service column to register this App ID and configure a certificate for this App ID. Click the ‘Configure’ link next to your desired App ID. In the Configure App ID page, check the Enable Push Notification Services box and click the Configure button. Clicking this button launches the APNs Assistant, which guides you through the next series of steps that create your App ID specific Client SSL certificate. Download the Client SSL certificate file to your download location. Navigate to that location and double-click the certificate file (which has an extension of cer) to install it in your keychain. When you are finished, click Done in the APNS Assistant. Double-clicking the file launches Keychain Access. Make sure you install the certificate in your login keychain on the computer you are using for provider development. The APNs SSL certificate should be installed on your notification server. When you finish these steps you are returned to the Configure App ID page of the iPhone Dev Center portal. The certificate should be badged with a green circle and the label “Enabled”. To complete the APNs set-up process, you will need to create a new provisioning profile containing your APNs-enabled App ID. IS it posssible to do theses steps through code.

  • How difficult is it to migrate away from Google App Engine?

    - by Ignas Limanauskas
    I am thinking of making an (initially) small Web Application, which would eventually have a potential to grow. All things considered Google App Engine seems like a very attractive option. Say, user base and complexity grows and for one or other reason I needed to leave GAE behind. How difficult would it be to migrate away? 1) Does GAE provide a way to export the database? What format would it be? Would it be difficult to put it under MySQL (or similar)? 2) In which areas (ex. database access, others?) would I have to use GAE API? I.e. which parts of implementation would have to be abstracted away / interfaced? 3) Alternatively, is it even worth to keep GAE API outside, say, if there is nothing much I would need to use.

  • How to determine cpu, ram needed for rails app?

    - by Ben
    What is the most accurate way to determine the amount of cpu speed and ram needed to run my rails app? I believe there are stress testing tools like Tsung, but how do I determine, for example, that I need X more ram, or X more CPU? I would like to find some way to roughly gauge the performance needs of my application so I can anticipate future needs. I think this data will also be useful for me to decide whether to upgrade one machine, or get another dedicated machine and put all the databases on that one. Essentially, I am concerned about scaling issues, and how to anticipate them. Thanks in advance for the help!

  • Does scheduling recycling app pool in IIS7 help the server conserve memory better?

    - by user29266
    Hello, I have a VPS (IIS7 with Win 2008) It's got: 40 websites and a SQL Server 2008 powering them with only 2 Gigs of RAM. None of the sites are mission critical, they are all just demos. I often have ram issues on the server because each site has does caching and generally uses a lot of memory. Would it make sense to set the application pools to recycle every 3 hours? I'm sure this would free up any memory leaks or processes left "hanging" Are there any other tips on this? Thank you very much!, Aron

  • Power management on Android -- is app CPU correlated to power usage? [closed]

    - by foampile
    2 questions: Is application CPU usage on Android correlated and how highly to battery usage? In other words, are apps that suck a lot of CPU also draining the battery or not necessarily? Is there a way to itemize and display the phone's power use by application, at any given point in time as well as within defined time buckets and maybe view charts and such? Sort of like a diagnostic monitor for power usage by application or system component? Thanks

  • Should app config files be in jboss/bin directory?

    - by djangofan
    I am a Integration Engineer for a software company. My development team has generated various jboss .ear applications that rely on configuration files being in the jboss/bin directory and setting the CLASSPATH externally using batch files (on Windows from an external LIB directory) rather than using jboss's internally loaded classes. Is this the right/standard way of doing things? Would some other location be better (for the config files) such as jboss/server/instancename/deploy or some other directory? Any opinons on how I can direct my development team to doing things in a best practices fashion?

  • NSTimer freezes the app until it gets fired again?

    - by itai alter
    Hello all, I have a simple app with a button, UIImageView and a NSTimer. The timer is fired up every 5 seconds repeatedly to update the ImageView with a new image, while the button simply stops the timer and switches to another View. The problem is that when I press the button, nothing happens for a few seconds (until the timer fires up again). Is there a way to cause the button to stop the timer and do its job at any given time instead of between intervals of the timer? Thanks!
