  • iPhone app crashes at the mid of running or during launch

    - by Sankar Chandra Bose
    Goodafternoon All! I have an issue in my application.My iphone application crashes at mid of running or during the application launch at times both in iPhone and simulator. I know that memory management is not proper or is it because os some other reason. My application is using a web service that pulls the data and displays it in the view,the working of web service is proper,because i see the data coming from the service in my app. Can anybody suggest how to manage memory properly (i.e,) where i have to release the objects,what are the objects that has to be released and the objects that should not be released. Kindly suggest a solution to the problem. Thanks in advance

  • Custom event listener on Android app

    - by Bilthon
    Hi everybody, I need to set up a simple event listener to refresh a listview from once in a while. The problem is I don't know how could I generate an event. I know that for events like key or button pressing I just need to implement the handler. But in this specific case I actually need to generate the event, which will be fired everytime another running thread of my app wakes up and refreshes it's list of news from a rss feed. I've done everything, but got stucked in here. Can I get any suggestion or link with some more info on how to implement this? Thanks Nelson R. Perez

  • Authentication Error in C# Send Mail App

    - by doc
    I'm developing a simple send mail app in C#, using my CMail Server: MailMessage mail = new MailMessage("[email protected]", "[email protected]"); mail.Subject = "Sub"; mail.Body = "Hi!"; SmtpClient smtp = new SmtpClient("MyServer"); System.Net.NetworkCredential cred = new System.Net.NetworkCredential("user", "pass"); smtp.UseDefaultCredentials = false; smtp.Credentials = cred; smtp.Send(mail); Obviously i ommited my account information, so, this code throws me an Authentication Exception for some reason. I first thought that the code was wrong, so i change the info to my gmail account and everything goes fine, with the only SMTP server that i having trouble is with the CMail. Is there a problem with .NET and CMail's SMTP ? Thanks for the help and comments!

  • iPhone checklist app

    - by Brodie4598
    I am trying to create a simple app that displays a list of items with check boxes next to each item, then give the user to simply check each box. Nothing (aside from the checkbox image switching) needs to happen when the check box is touched. Each checklist is a seperate NSDictionary contained in a single master NSDictionary. The checklist dictionary contains arrays for different sections of each checklist. At the top of the view, the user selects which set (dictionary) of checklists they want to open then I want that checklist to display underneath the picker once a "select checklist" button is pressed. Any ideas on the best way to get this done?

  • Is there a ".d" directory to use to load modules at boot time, opposed to /etc/modules?

    - by gertvdijk
    I am automating some configurations on my systems using Puppet. For a group of machines I want to load a kernel module at boot time. The most elegant way seems to edit /etc/modules and add one on an individual line. However, I would like to use separate files in a ".d" directory structure for easier maintainability. For modprobe and specifying the options for modules, there's /etc/modprobe.d/, but what's the most elegant way for actually loading modules at boot time using a single new file? Basically, I'm looking for the non-existing /etc/modules.d/ directory. Any suggestions?

  • How can I use a config-file in Expression Blend 4?

    - by sofri
    Hi, while trying to use the "InfoStrat"-Bing-Maps-Control in Expression Blend 4 for my Surface Application, I get the error message: "Mixed mode assembly is built against version v2.0.50527 of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information" I already found out that I need to write this configfile: <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup> </configuration> But Expression Blend doesn't seem to recognize that it is there. So how can I solve this problem?

  • how to read in a list of custom configuration objects

    - by Johnny
    hi, I want to implement Craig Andera's custom XML configuration handler in a slightly different scenario. What I want to be able to do is to read in a list of arbitrary length of custom objects defined as: public class TextFileInfo { public string Name { get; set; } public string TextFilePath { get; set; } public string XmlFilePath { get; set; } } I managed to replicate Craig's solution for one custom object but what if I want several? Craig's deserialization code is: public class XmlSerializerSectionHandler : IConfigurationSectionHandler { public object Create(object parent, object configContext, XmlNode section) { XPathNavigator nav = section.CreateNavigator(); string typename = (string)nav.Evaluate("string(@type)"); Type t = Type.GetType(typename); XmlSerializer ser = new XmlSerializer(t); return ser.Deserialize(new XmlNodeReader(section)); } } I think I could do this if I could get Type t = Type.GetType("System.Collections.Generic.List<TextFileInfo>") to work but it throws Could not load type 'System.Collections.Generic.List<Test1.TextFileInfo>' from assembly 'Test1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

    - by Brian
    Thanks for the help. Currently I import in gae: from google.appengine.ext.webapp import template then use this to render: self.response.out.write(template.render('tPage1.htm', templateInfo )) I believe the template that Google supplied for Django templete is version 0.96. How do I setup and import the newer version of only the Django template version 1.2.1? Brian

  • Stream PDF to another local App

    - by Nathan
    Hi, I'm currently trying to optimize a small firefox extension that will grab a pdf off the current document and send it to a port that another local application is listening on. Right now it uses a terrifying hackjob of cache viewer. The way I'm getting it is loading the cache, searching through it using the current URL and grabbing the file and saving it to a temp directory. Then I stream the file in, delete the temp, and send it through the socket. Now, my new design, ideally I'd want to build it from scratch and cut out saving it to the local machine at all, and just stream it through the socket. I've been looking at doing something like, //check page to ensure its a pdf //init in/out streams //stream through sock //flush Now, this would be vastly superior to the 400 line hacked up mess I have now, but I'm new to building FF extensions, and after reading a lot about URIs and the file streaming and such I'm probably more confused than when I started trying to fix this three hours ago. I'm okay with sending things through the sockets and whatnot, I understand that, I'm mainly confused about what multitude of interfaces I want to use. Gah! Thanks! Also, long time reader, first time poster!

  • Unique task queue task names only for active duration

    - by antony.trupe
    I want to guarantee that a task is not in a task queue more then once, so I generate a unique name based on it's payload. But, that task name is reserved for up to 7 days, which is not what I want; I only want it reserved for the duration the task is queued; it could be immediately re-queued. Once a Task with name N is written, any subsequent attempts to insert a Task named N will fail. Eventually (at least seven days after the task successfully executes), the task will be deleted and the name N can be reused. Is there a way to check if the named task is already in the queue then add it if it's not? Or a totally different approach?

  • Is it safe to change the 'Security.salt' line to a more lengthy string {64 hex key}

    - by Gaurav Sharma
    Hi everyone, I have changed the Configure::write('Security.salt', '############'); value in the file config/core.php file to a '256-bit hex key'. Is it safe or a good practice to change these lines for every different installation of cakephp application or shall I revert back to the original ? I also changed the Configure::write('Security.cipherSeed','7927237598237592759727'); to a different one of more length. Please throw some light on this. Thanks

  • Problem while configuring the file Delimeter("\t") in app.config(C#3.0)

    - by Newbie
    In my app.config file I made the setting like the following <add key = "Delimeter" value ="\t"/> Now while accessing the above from the program by using the below code string delimeter = ConfigurationManager.AppSettings["FileDelimeter"].ToString(); StreamWriter streamWriter = null; streamWriter = new StreamWriter(fs); streamWriter.BaseStream.Seek(0, SeekOrigin.End); Enumerable .Range(0, outData.Length) .ToList().ForEach(i => streamWriter.Write(outData[i].ToString() + delimiter)); streamWriter.WriteLine(); streamWriter.Flush(); I am getting the output as 18804\t20100326\t5.59975381254617\t 18804\t20100326\t1.82599797249479\t But if I directly use "\t" in the delimeter variable I am getting the correct output 18804 20100326 5.59975381254617 18804 20100326 1.82599797249479 I found that while I am specifying the "\t" in the config file, and while reading it into the delimeter variable, it is becoming "\\t" which is the problem. I even tried with but with no luck. I am using C#3.0. Need help

  • App logicstics & changes due to scope creep

    - by Kevin Brown
    I started an app that was initially a testing platform--user management, and managers that can view their employees tests. Recently, functionality has been extended (not built yet) to allow users to complete a test in place of an employee--basically adding a record, but no user. I have three tables in use for this: users(contains user info for login/security), profiles (all personal info: address, height, etc.), and survey (contains survey answers for user). How do I extend my application to encompass this functionality with minimal change to the structure? I assume that the best way to do this would be to insert records to the tables profiles and survey, and have no username/password/email? There MUST be a user_id associated b/c the tables are linked through the user_ids...

  • Show UIView for app presentation only once in iOS

    - by André Muniz
    I need to show an UIScrollView with some pages for present the app to user when launched for the first time. My slides are working correctly, lefting the logic to present it. Is a good practice to set the UIScrollViewController as root controller and set a NSUserDefault variable to control the presentation and redirect to main controller or set the main ViewController as root normally and call the presentation view if needed is a better approach? If there is a better way to do this can someone help? Thanks.

  • Worklight console app, update

    - by jarkko
    We're using Worklight 6.1.0.0 / WebSphere 8.0.0.2 (ND/aix). This seemed pretty close to my question too, but for version 6.0. I've successfully done uninstall/install to our worklight console war package. However, there is some extra work on re-deploying adapters and such. I was looking for a way to just update the console. Among the ant tasks there is a target 'minimal-update', which sounds like what I'm looking for (is it?). However when all other pieces fell into place, I have an error for mapping the datasources: ADMA0007E: A validation error occurred in task Mapping resource references to resources. The Java Naming and Directory Interface (JNDI) name is not specified for resource reference jdbc/WorklightDS in module Worklight with EJB name . Contents of the 'minimal-update' task is pretty much the same as for 'install'. I tried that as update from websphere admin console (but i should use the ant task - right?), that gave me a wizard screen to map jdbc/WorklightDS from package to jdbc/WorklightDS on server. This left me wondering how could I tell this using the ant task.

  • Unable to persist objects in GAE JDO

    - by Basil Dsouza
    Hello Guys, I am completely fresh to both JDO and GAE, and have been struggling to get my data layer to persist any code at all! The issues I am facing may be very simple, but I just cant seem to find any a way no matter what solution I try. Firstly the problem: (Slightly simplified, but still contains all the info necessary) My data model is as such: User: (primary key) String emailID String firstName Car: (primary key) User user (primary key) String registration String model This was the initial datamodel. I implemented a CarPK object to get a composite primary key of the User and the registration. However that ran into a variety of issues. (Which i will save for another time/question) I then changed the design as such: User: (Unchanged) Car: (primary key) String fauxPK (here fauxPK = user.getEmailID() + SEP + registration) User user String registration String model This works fine for the user, and it can insert and retrieve user objects. However when i try to insert a Car Object, i get the following error: "Cannot have a java.lang.String primary key and be a child object" Found the following helpful link about it: http://stackoverflow.com/questions/2063467/persist-list-of-objects Went to the link suggested there, that explains how to create Keys, however they keep talking about "Entity Groups" and "Entity Group Parents". But I cant seem to find any articles or sites that explain what are "Entity Group"s or an "Entity Group Parents" I could try fiddling around some more to figure out if i can store an object somehow, But I am running sort on patience and also would rather understand and implement than vice versa. So i would appreciate any docs (even if its huge) that covers all these points, and preferably has some examples that go beyond the very basic data modeling. And thanks for reading such a long post :)
