  • How do I save my whole program?

    - by user1444829
    What argument should be in this missing part of formatter.Serliaze to get the program to save just the program as a .exe? Ignore the Openfiles. class FileOption { OpenFileDialog openDialog = new OpenFileDialog(); SaveFileDialog saveDialog = new SaveFileDialog(); BinaryFormatter formatter = new BinaryFormatter(); public void Open() { } public void Save() { if (saveDialog.ShowDialog() == DialogResult.OK) { FileStream file = new FileStream(saveDialog.FileName, FileMode.Create); formatter.Serialize(file, x); // x means that i havent set anything there yet// file.Close(); } } }

  • Automatically create an admin user when running Django's ./manage.py syncdb

    - by a paid nerd
    My project is in early development. I frequently delete the database and run manage.py syncdb to set up my app from scratch. Unfortunately, this always pops up: You just installed Django's auth system, which means you don't have any superusers defined. Would you like to create one now? (yes/no): Then you have supply a username, valid email adress and password. This is tedious. I'm getting tired of typing test\[email protected]\ntest\ntest\n. How can I automatically skip this step and create a user programatically when running manage.py syncdb ?

  • How to use Mahout in a Windows environment?

    - by oopdemo
    I am trying to use Mahout in an application running on Windows. I want to build clusters from a lucene index using k-means. As soon as I have to create sequence files (creating vectors from a lucene index), I get a Hadoop-Exception, since Hadoop makes command line calls to programs unknown in a Windows environment (e.g. chmod). Running in Cygwin is not an option, since I want to be able to run the App from eclipse. So my question is is there a way to avoid having to create sequence files to retrieve my vectors from a lucene index? or is there a way to create sequence files in a Windows environment?

  • iPhone Provisioning Profile problems...

    - by James
    I have already successfully submitted two apps to the app store, so I should be able to do it by now, right? With my most recent app, however, I'm having a bear of a time with getting the Application Identifier or Bundle Identifier set up. In my distribution profile, I have included the identifier "com.jmock.irowbeta", and then copied it exactly into the the app's Info.plist file under "Bundle Identifier". In the past, this has done the trick, but now I'm getting the error Provisioning profile 'irow beta' specificies the identifier 'com.jmock.irowbeta' which doesn't match the current setting 'com.yourcompany.irow-beta'. So it seems that its somehow still using the default of com.yourcompany.APPLICATION_NAME, but it shouldn't after I have changed it in the Info.plist, right? I think this means that xcode isn't recognizing that PLIST for some reason, because when I change the name of the icon file, for example, or other such attributes, nothing changes. If this is the problem, how do I make xcode recognize the PLIST? Otherwise, what the heck is going on? Thanks, James

  • what is the best way to generate fake data for classification problem ?

    - by Berkay
    i'm working on a project and i have a subset of user's key-stroke time data.This means that the user makes n attempts and i will use these recorded attempt time data in various kinds of classification algorithms for future user attempts to verify that the login process is done by the user or some another person. (Simply i can say that this is biometrics) I have 3 different times of the user login attempt process, ofcourse this is subset of the infinite data. until now it is an easy classification problem, i decided to use WEKA but as far as i understand i have to create some fake data to feed the classification algorithm. can i use some optimization algorithms ? or is there any way to create this fake data to get min false positives ? Thanks

  • Django: Overriding the clean() method in forms - question about raising errors

    - by Monika Sulik
    I've been doing things like this in the clean method: if self.cleaned_data['type'].organized_by != self.cleaned_data['organized_by']: raise forms.ValidationError('The type and organization do not match.') if self.cleaned_data['start'] > self.cleaned_data['end']: raise forms.ValidationError('The start date cannot be later than the end date.') But then that means that the form can only raise one of these errors at a time. Is there a way for the form to raise both of these errors? EDIT #1: Any solutions for the above are great, but would love something that would also work in a scenario like: if self.cleaned_data['type'].organized_by != self.cleaned_data['organized_by']: raise forms.ValidationError('The type and organization do not match.') if self.cleaned_data['start'] > self.cleaned_data['end']: raise forms.ValidationError('The start date cannot be later than the end date.') super(FooAddForm, self).clean() Where FooAddForm is a ModelForm and has unique constraints that might also cause errors. If anyone knows of something like that, that would be great...

  • Interview question: Develop an application that can display trail period expires after 30 days witho

    - by Algorist
    Hi, I saw this question in a forum about how an application can be developed that can keep track of the installation date and show trail period expired after 30 days of usage. The only constraint is not to use the external storage of any kind. Question: How to achieve this? Thanks Bala --Edit I think its easy to figure out the place to insert a question work. Anyway, I will write the question clearly. "external storage" means don't use any kind of storage like file, registry, network or anything. You only have your program.

  • java generics covariance

    - by soocracy42
    I am having trouble understanding the following article: http://www.ibm.com/developerworks/java/library/j-jtp01255.html Under, Generics are not covariant the author states, Because ln is a List, adding a Float to it seems perfectly legal. But if ln were aliased with li, then it would break the type-safety promise implicit in the definition of li -- that it is a list of integers, which is why generic types cannot be covariant. I can't understand the part where it says "if ln were aliased with li". What does the author means by alias?(reference?). The code snippet above the quoted line seems to illustrate WHAT is illegal in java and not WHY. It would be very helpful to me if somebody could explain with an example. Thanks in advance.

  • learning OO with PHP

    - by dole doug
    Hi there I've started to learn OO programming, but using the PHP language with the help of the "PHP 5 Objects, Patterns, and Practice" book. The thing is that I wish to learn to use into same time the CakePHP framework which make use a lot of the MVC pattern. Because I don't know much about OO and less about MVC I wish to understand the later one but assumptions I make with my OO knowledges might have bad impact on long term. Does anyone know a good tutorial about what means MVC (more than cakephp manual says about it, but more easy to read/understand than wikipedia)? TY

  • Limit a program's execution time in C (Monte Carlo technique)

    - by rrs90
    I am working on a project which has no determined algorithm to solve using C language. I am Using Monte Carlo technique for solving that problem. And the number of random guesses I want to limit to the execution time specified by the user. This means I want to make full use of the execution time limit defined by the user (as a command line argument) to make as many random iterations as possible. Can I check the execution time elapsed so far for a loop condition. Eg: for(trials=0;execution_time P.S. I am using code blocks 10.05 for coding and GNU compiler.

  • Signup form using Braintree Transparent Redirect

    - by Robin Fisher
    Hi, I'm developing an application in Rails and want the user to be able to signup and provide their card details on one form. I'm using the Braintree API and their transparent redirect, which means that the form data is posted directly to Braintree. How can I store and later retrieve the non-payment related information provided by the user from that form e.g. account name, username? These values are not returned in the response provided by Braintree. If you look at the Basecamp signup process, this is the result I want to achieve. Thanks Robin

  • python: subclass a metaclass

    - by Michael Konietzny
    Hello, for putting methods of various classes into a global registry I'm using a decorator with a metaclass. The decorator tags, the metaclass puts the function in the registry: class ExposedMethod (object): def __init__(self, decoratedFunction): self._decoratedFunction = decoratedFunction def __call__(__self,*__args,**__kw): return __self._decoratedFunction(*__args,**__kw) class ExposedMethodDecoratorMetaclass(type): def __new__(mcs, name, bases, dct): for obj_name, obj in dct.iteritems(): if isinstance(obj, ExposedMethod): WorkerFunctionRegistry.addWorkerToWorkerFunction(obj_name, name) return type.__new__(mcs, name, bases, dct) class MyClass (object): __metaclass__ = DiscoveryExposedMethodDecoratorMetaclass @ExposeDiscoveryMethod def myCoolExposedMethod (self): pass I've now came to the point where two function registries are needed. The first thought was to subclass the metaclass and put the other registry in. For that the new method has simply to be rewritten. Since rewriting means redundant code this is not what I really want. So, it would be nice if anyone could name a way how to put an attribute inside of the metaclass which is able to be read when new is executed. With that the right registry could be put in without having to rewrite new. Thanks and Greetings, Michael

  • Collection <NSCFSet: 0x1b0b30> was mutated while being enumerated. How to determine which set?

    - by jamone
    I'm doing a bunch of core data inserts and after 20k or so inserts with saves every 1-2k I get this error: Terminating app due to uncaught exception 'NSGenericException', reason: '*** Collection <NSCFSet: 0x1b0b30> was mutated while being enumerated.' I'm trying to figure out which NSSet is causing this. I've done a search and the only NSSets in my code are the autogenerated ones that handle the Core Data relationships. I'm using NSXMLParser and for each element found creating a new entity (if a matching one doesn't already exist). So I will create a state entity and then populate all the city entities and then do a save. This means that a state's NSSet *cities is getting added to but I don't see why you can't do that.

  • Passing paramenters on the stack

    - by oxinabox.ucc.asn.au
    When you pass parameters to a function on the cpu stack, You put the parameters on then JSR puts the return address on the stack. So than means in your function you must take the top item of the stack (the return address) before you can take the others off) eg is the following the correct way to go about it: ... |Let’s do some addition with a function, MOVE.L #4, -(SP) MOVE.L #5, -(SP) JSR add |the result of the addition (4+5) is in D0 (9) ... add: MOVE.L (SP)+, A1 |store the return address |in a register MOVE.L D0, -(SP) |get 1st parameter, put in D0 MOVE.L D2, -(SP) |get 2nd parameter, put in D0 ADD.L D2, D0 |add them, |storing the result in D0 MOVE.L A1, -(SP) |put the address back on the |Stack RTS |return

  • XCOPY-deploying Microsoft Sync Framework in a no admin rights scenario (i.e. ClickOnce install)

    - by Mike Bouck
    I'm currently designing a smart client app (WPF) which needs to operate in an "occasionally disconnected" mode. For the offline scenario, I'm looking at using: Disconnected Service Agent Application Block (from the Smart Client Software Factory) Microsoft Sync Framework I should mention that I want my smart client app to be XCOPY-deployable, auto-updating, and installable without administrative privledges -- basically a ClickOnce-deployed app. From what I can tell this means the Microsoft Sync Framework is out because it has some COM in it's implementation that needs to get registered on the client which requires admin rights. Is it possible to XCOPY deploy and run MSF from a ClickOnce app? Any other ideas for data synchronization?

  • Is anyone else receiving a QUOTA_EXCEEDED_ERR on their iPad when accessing localStorage?

    - by Kevin
    I have a web application written in JavaScript that runs successfully on the desktop via Safari as well as on the iPhone. We are looking at porting this application to the iPad and we are running into a problem where we are seeing QUOTA_EXCEEDED_ERR when storing a relatively small amount of data within the localStorage on the device. I know what this error means, but I just don't think I'm storing all that much data. Is anyone else doing something similar? And seeing/not seeing this problem? Kevin...

  • HiLo: how to control Low values

    - by Sandor Drieënhuizen
    I'm using the HiLo generator in my S#rpArchitecture/NHibernate project and I'm performing a large import batch. I've read somewhere about the possibility to predict the Low values of any new records because they are generated on the client. I figure this means I can control the Low values myself or at least fetch the next Low value from somewhere. The reason I want to use this is that I want to set relations to other entities I'm about to insert. They do not exist yet but will be inserted before the batch transaction completes. However, I cannot find information about how to set the Low values or how to get what Low value is up next. Any ideas?

  • WPF Application that only has a tray icon

    - by Michael Stum
    I am a total WPF newbie and wonder if anyone could give me some pointers how to write an application that starts minimized to tray. The idea is that it periodically fetches an RSS Feed and creates a Toaster-Popup when there are new feeds. The Application should still have a Main Window (essentially just a list containing all feed entries), but that should be hidden by default. I have started reading about XAML and WPF and I know that the StartupUri in the App.xaml has to point to my main window, but I have no idea what the proper way is to do the SysTray icon and hide the main window (this also means that when the user minimizes the window, it should minimize to tray, not to taskbar). Any hints?

  • making urllib request in Python from the client side

    - by mridang
    Hi Guys, I've written a Python application that makes web requests using the urllib2 library after which it scrapes the data. I could deploy this as a web application which means all urllib2 requests go through my web-server. This leads to the danger of the server's IP being banned due to the high number of web requests for many users. The other option is to create an desktop application which I don't want to do. Is there any way I could deploy my application so that I can get my web-requests through the client side. One way was to use Jython to create an applet but I've read that Java applets can only make web-requests to the server it is deployed on and the only way to to circumvent this is to create a server side proxy which leads us back to the problem of the server's ip getting banned. This might sounds sound like and impossible situation and I'll probably end up creating a desktop application but I thought I'd ask if anyone knew of an alternate solution. Thanks.

  • Ajax and Brower Navigation for Back/Forward

    - by David Rodecker
    I am using a ASP.net form with custom onclick mouse events to modify data values. Upon clicking and updating the values, one div section of the form performs a postback. onclick="__doPostBack('ctl01$phCon1$gridReports','sel1')" This is working well, however when the browser BACK option is selected, the browser opens goes through the history of the DIV ajax/onclick actions prior to going back to the prior URL. I suspect that this may be due to the doPostBack being treated as a browsing operation. Is there a means to perform the necessary ASP.net code events to make the page work, but not have the action stored in the browser history?

  • Activity tracking usecase for login tracking.

    - by Mdillion
    Creating an activity tracking system for a social site. All user activiti from pooint of login til logoff are to be tracked. This means the first use case is the user's login. Every activity will have the same format so once I figure out how to track one activity then I can create chema for all activities. Currently for login I have steps like: Two solutions I have: Activity 1: User attempts to login Activity 2 A: User has successfully logged in Activity 2 B: User failed to login. Activity 2 B A: User failed to login due to invalid password Activity 2 B B: User failed to login due to locked account. OR Activty 1: User login - with result = Pass or Fail and if Fail reason = flag_id of reason. Accordingly I have to create the schema. For now I have it like this: activity_id object_id (fk) session_id (fk) user_id (fk) flag_id (fk) created_dt friend_id (fk) result (pass/fail) But ofcourse this a work in progress.

  • Telling a UITextField to become first responder while embedded in a UITableViewCell

    - by Jasarien
    I have a UITextField that is a subview of a UITableViewCell. When my view loads, I want the text field to become first responder. I have a pointer to the text field in the table cell, so to do this I am trying: [myTextField becomeFirstResponder]; This returns NO all the time, regardless of when it's called, which according to the docs means the text field refused to become first responder... What am I doing wrong? Edit: The text field properly responds to being touched. It bring up the keyboard then. It's only when telling it to become first responder programmatically that the problem happens.

  • DoDragDrop disables MouseMove Events

    - by stefan.at.wpf
    After having started a Drag & Drop operation by DragDrop.DoDragDrop(...) no more MouseMove Events are fired. I even tried AddHandler(Window.MouseMoveEvent, new MouseEventHandler(myControl_MouseMove), true); where the last parameter means I even opt in for handled events. No chance, seems like the MouseMove Event is never fired at all! Any way to still get MouseMove Events while using Drag & Drop? I'd like to Drag & Drop a control, while dragging this control it shall follow the mouse pointer. Any idea how to do this in this case?

    Hi, i've seen many article on encrypt/decrypt of file and typically a button is used to choose the file for encrypt and another button to decrypt the file. i've seen some application like truecrypt and probably others which does file encryption on-the-fly with transparent. this means that when a encrypted file is clicked to access, it will automatically decrypt and play/open the file. then when the file is closed, it will automatically encrypt again. what are the ways to do this in c# compact framework?
