  • jEdit+JythonInterpreter: how to import java class?

    - by JChao
    Hi, I'm running jEdit with the JythonInterprete and I have a .jar file called JavaTest.jar. JavaTest has a class called SampleJavaClass which has a method printerCount. From my .py file, I want to do: from javatest import SampleJavaClass class SampleClass(SampleJavaClass): def pymain(self): SampleJavaClass.printerCount(4) Java code: package javatest; public class SampleJavaClass { public static void printerCount(int i){ for(int j=0; j< i; j++){ System.out.println("hello world"); } } (etc...) In the JythonInterpreter, I have already tried clicking "Edit Jython Path" and adding the .jar file then running the interpreter again, but it still gives me ImportError: cannot import name SampleJavaClass

  • Java training for .NET developers?

    - by C Keene
    We are working with a large retail bank on training 40-50 .Net developers to use Java. They are familiar with C# and .Net framework and have built dozens of "run the business" style apps in .Net. We need advice on how to provide basic Java familiarity, with a focus on back end logic, security and transaction management. Back end is Spring/Hibernate, front end is Ajax (Dojo). Are there any online, self-paced, Java courses that would be good for C#/.Net developers to get up to speed quickly?

  • How to get path to current exe file on Linux?

    - by user1519221
    The code below gives current path to exe file on Linux: #include <iostream> std::string getExePath() { char result[ PATH_MAX ]; ssize_t count = readlink( "/proc/self/exe", result, PATH_MAX ); return std::string( result, (count > 0) ? count : 0 ); } int main() { std::cout << getExePath() << std::endl; return 0; } The problem is that when I run it gives me current path to exe and name of the exe, e.g.: /home/.../Test/main.exe I would like to get only /home/.../Test/ I know that I can parse it, but is there any nicer way to do that?

  • Display the y value of a uiImageView during an animation

    - by user1422132
    I have the following code: NSString *yValue; yValue=[[NSString alloc] initWithFormat:@"%1.2f" , imageView.center.y]; CGRect labelFrame = CGRectMake( 10, 100, 200, 50 ); UILabel* label5 = [[UILabel alloc] initWithFrame: labelFrame]; [label5 setBackgroundColor:[UIColor blackColor]]; [label5 setText: yValue]; [label5 setTextColor: [UIColor orangeColor]]; [self.view addSubview: label5]; This correctly shows the y value of the UIimageView but the problem is that it only shows the ending y value. When a person flicks the UIImageView I animate it using: [UIView animateWithDuration:2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{ recognizer.view.center = finalPoint; } What I want is the label5 to display the y value of the imageView during the animation not just after. Is it possible to do this?

  • How to implement action in didSelectRowAtIndexPath of UITableview?

    - by Sumana Mehta
    On my view, I used to have few buttons and each button had an action associated with it. UIButton *testButton = [[UIButton alloc] initWithFrame:CGRectMake(120,300,90,90)]; [testButton setBackgroundImage:[UIImage imageNamed:@"test.jpg"] forState:UIControlStateNormal]; [testButton addTarget:self.view action:@selector(gotoProd:) forControlEvents:UIControlEventTouchUpInside]; [testButton addt [scrollView testButton]; But now I am trying to replace all those buttons with the tableview with rows. I was able to populate the rows and I know one needs to use didSelectRowAtIndexPath for handling on select event of the cell. But how can I implement action:@selector(gotoProd:) in tableviews ?? Any help will be greatly appreciated.

  • Annotation based data structure visualization - are there similar tools out there?

    - by Helper Method
    For a project at university I plan to build an annotation based tool to visualize/play around with data structures. Here's my idea: Students which want to try out their self-written data structures need to: mark the type of their data structures using some sort of marker annotation e.g. @List public class MyList { ... } so that I know how to represent the data structure need to provide an iterator so that I can retrieve the elements in the right order need to annotate methods for insertion and removal, e.g. @add public boolean insert(E e) { ... } so that I can "bind" that method to some button. Do similar applications exist? I googled a little bit around but didn't find anything like that.

  • Using iPhone Core Data to many Relationship

    - by BLeB
    When I define a to many relationship between entities in Xcode and then generate the data class from the entity I get a header with the following methods defined: @interface PriceList (CoreDataGeneratedAccessors) - (void)addItemsObject:(PriceListItem *)value; - (void)removeItemsObject:(PriceListItem *)value; - (void)addItems:(NSSet *)value; - (void)removeItems:(NSSet *)value; @end When I attempt to call addItemsObject with the following code a doesNotRecognizeSelector exception is thrown. PriceListItem *item = [NSEntityDescription insertNewObjectForEntityForName:@"PriceListItem" inManagedObjectContext:managedObjectContext]; item.cat = [attributeDict valueForKey:@"c"]; item.sel = [attributeDict valueForKey:@"s"]; [self addItemsObject:item]; From what I have read I do not have to implement these methods and that they are generated at runtime. Any ideas?

  • Settings cell selected background view removes backgroundview

    - by Chris
    I'm trying to set up custom UITableViewCells. I can set the backgroundView no problem, but if I set selectedBackgroundView, the cell's background becomes white and only the selected background is seen: - (void) createCell: (UITableViewCell*)cell onRow: (NSUInteger)row { UIImageView* bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cell_background_red.png"]]; cell.backgroundView = bgImage; cell.selectedBackgroundView = bgImage; cell.textLabel.hidden = YES; UILabel* titleLabel = [[UILabel alloc] initWithFrame: CGRectMake(20, CGRectGetHeight(cell.frame) / 2, 200, 50)]; titleLabel.text = [[self.ruleList objectAtIndex: row] objectForKey: TitleKey]; titleLabel.backgroundColor = [UIColor clearColor]; [cell.contentView addSubview: titleLabel]; }

  • Pattern for unidirectional has_many join?

    - by Kris
    It occurred to me that if I have a has_many join, where the foreign model does not have a belongs_to, and so the join is one way, then I don't actually need a foreign key. We could have a column, category_ids, which stores a marshaled Array of IDs which we can pass to find. So here is an untested example: class page < AR def categories Category.find(self.category_ids) end def categories<<(category) # get id and append to category_ids save! end def category_ids @cat_ids ||= Marshal.load(read_attribute(:category_ids)) rescue [] end def category_ids=(ids) @cat_ids = ids write_attribute(:category_ids, ids) end end page.category_ids = [1,4,12,3] page.categories = Array of Category Is there accepted pattern for this already? Is it common or just not worth the effort?

  • Query SQL Server Database from native iOS Application

    - by mbm30075
    I am working on an in-house, iOS app that will need read-only access to a SQL Server with multiple databases. I know the stock answer here is "write some web services", but I'd like a solution that is self-contained. Is there any way to directly connect to a SQL Server database from an iOS application? I'm thinking something like a basic ODBC connection. I've seen a lot of users asking this question, but very few answers other than "write a web service." Is that really the only way?

  • Unable to Access UILabel in UITableViewCell

    - by Nirmal
    I am having trouble in accessing which is in the UITableViewCell, that i have placed in my main .xib file. That Label is connected to IBOutlet servicesCell.

  • Rails Authlogic authentication method

    - by Rabbott
    Within Authlogic, is there a way that I can add conditions to the authentication method? I know by using the find_by_login_method I can specify another method to use, but when I use this I need to pass another parameter since the find_by_login_method method only passes the parameter that is deemed the 'login_field'. What I need to do is check something that is an association of the authentic model.. Here is the method I want to use # make sure that the user has access to the subdomain that they are # attempting to login to, subdomains are company names def self.find_by_email_and_company(email, company) user = User.find_by_email(email) companies = [] user.brands.each do |b| companies << b.company.id end user && companies.include?(company) end But this fails due to the fact that only one parameter is sent to the find_by_email_and_company method. The company is actually the subdomain, so in order to get it here I am just placing it in a hidden field in the form (only way I could think to get it to the model) Is there a method I can override somehow..?

  • Get Flickr Sets

    - by PaulAdamDavis
    Hi everyone. Usual stuff, Googled forever, looked on here, no help. Yet. What I want is to list the sets of photos I have on Flickr. Nice & simple, it would seem. I want the 'title image' (the one used as the thumb for it on Flickr its self), the title and URL. Can't be that hard, can it? The language of choice is PHP (5.1.6), or JS (jQuery if possible). Both are good.

  • Ruby Metaprogramming

    - by Veerendra Manikonda
    I am having a method which returns the price of a given symbol and i am writing a test for that method. This is my test def setup @asset = NetAssetValue.new end def test_retrieve_price_for_symbol_YHOO assert_equal(33.987, @asset.retrieve_price_for_a_symbol('YHOO')) end def test_retrive_price_for_YHOO def self.retrieve_price_for_a_symbol(symbol) 33.77 end assert_equal(33.97, @asset.retrieve_price_for_a_symbol('YHOO')) end This is my method. def retrieve_price_for_a_symbol(symbol) symbol_price = { "YHOO" => 33.987, "UPS" => 35.345, "T" => 80.90 } raise Exception if(symbol_price[symbol].nil?) symbol_price[symbol] end I am trying to mock the retrieve_price_for_a_symbol method by writing same method in test class but when i call it, the call is happening to method in main class not in the test class. How do I add that method to meta class from test and how do i call it? Please help.

  • NSManagedObjectID into NSData

    - by papr
    I found this wonderful NSManagedObjectID. This would be very good for referencing an Entity/NSManagedObject/NSEntityDescription, right? Let's get an ID from an entity: NSEntityDescription *entity = [self newEntity]; NSManagedObjectID *objID = [entity objectID]; So... any idea how to get this objID into a string? Or better: NSData. Actually something to be able to save it to the NSUserDefaults. ;-) Btw: NSFetchRequest doesn't want to work in my case. I use an modified version of this example: answer of an old question.

  • How to use NSWindowDidExposeNotification

    - by Jeena
    Hi, I am trying to update another windows when the one becomes visible. So I found the NSWindowDidExposeNotification and tried to work with it, so I wrote in my awakeFromNib: // MyClass.m - (void)awakeFromNib { NSNotificationCenter *nc = [NSNotificationCenter defaultCenter]; [nc addObserver:self selector:@selector(mentionsWindowDidExpose:) name:NSWindowDidExposeNotification object:nil]; } and implemented the method // MyClass.h - (void)mentionsWindowDidExpose:(id)sender; // MyClass.m - (void)mentionsWindowDidExpose:(id)sender { NSLog(@"test"); } But it never gets called which is odd. What do I do wrong here?

  • How to make my iphone app icon update like the weather app icon?

    - by Toret
    I have an application that I'm currently building that requires me to display a visual update on the application it self. example: The weather app displays 14 degrees celcius and some clouds as its application icon. When the weather changes there is an update to the way the icon looks without having to open the weather app. The applications icon changes to reflect the update in weather. You can then open the weather app to get more information if need be. In my application I need to have an update system like that which shows the user information without opening the application. If they would like more information they can open the application then. I have no idea how to accomplish this task at the moment. I hope someone will be able to help or point me in the right direction. Thank you for your time.

  • javascript: what are immediate functions used for [duplicate]

    - by tkoomzaaskz
    This question already has an answer here: Why using self executing function in JavaScript? [duplicate] 4 answers I've been programming in JS since some time, but I have never came upon a need of using immediate functions, for example: (function(){ console.log('hello, I am an immediate function'); }()) What would be the difference if I just wrote: console.log('hello, I am an immediate function'); ? I don't have any access to this function anyway (it is not assigned anywhere). I think (but I'm not sure) that I can implement everything without immediate functions - so why do people use it?

  • Failure when adding images to a thumbnail gallery

    - by Martin KS
    morning all, I've been browsing around trying to work out what I've done wrong when trying to add a thumbnail to a gallery view, but can't work out what on earth it might be. I'm trying to use the following code to stick a thumbnail onto a blank view: UIImageView *any = [[UIImageView alloc] initWithFrame:CGRectMake(a,b,70,60)]; any.image = [UIImage imageNamed:selectedThumbPath]; any.tag = 0; [self.view addSubview:any]; In the above example: a = 165 b = 150 selectedThumbPath = the full path to a thumbnail ie. /users/Cleverbum/library etc I'm pulling my hair out, there are no error messages, and no clues as to why it's not drawing anything. What's worse is that this is one of the only parts of the code i've not changed!

  • Singelton restricted to instance of dll

    - by codeySmurf
    If I create a singleton class in the context of a dll, the singleton class is instantiated once and used by all instances of the dll. I am using a dll as a plug-in for an application. Now the following thing came to my mind: If I use a singleton Class, it will be shared across multiple instances of the plug-in. However, this makes it difficult to manage the lifetime of the singleton class efficiently. The only way I could think of would be to use a reference count and to make the singleton delete its self when the reference count is 0. Does anyone have any better ideas on that? Is there any good way to restrict the singleton object to one instance of the dll? Language is c++

  • Seeking assistance with Escaping Data for MySQL queries

    - by JM4
    Please don't send me a link to php.net referencing mysql_real_escape_string as the only response. I have read through the page and while I understand the general concepts, I am having some trouble based on how my INSERT statement is currently built. Today, I am using the following: $sql = "INSERT INTO tablename VALUES ('', '$_SESSION['Member1FirstName'], '$_SESSION['Member1LastName'], '$_SESSION['Member1ID'], '$_SESSION['Member2FirstName'], '$_SESSION['Member2LastName'], '$_SESSION['Member2ID'] .... and the list goes on for 20+ members with some other values entered. It seems most people in the examples already have all their data stored in an array. On my site, I accept form inputs, action="" is set to self, php validation takes place and if validation passes, data is stored into SESSION variables on page 2 then redirected to the next page in the process (page 3) (approximately 8-10 pages in the whole process). thanks!
