  • Matlab: Print text in input field

    - by Adam Doyle
    Using Matlab, I have this code: value = input('>> Enter a value: '); and basically, I want a "default" value to the right of the colon (sortof like this) >> Enter a value: 12 where "12" is editable such that the user could [backspace] [backspace] and change the value to, say, "20" or something. Is there any (easy) way to do this? Thanks!

  • Custom Java events with listeners vs. a JMS based implementation?

    - by Joe Dean
    My application requires events to be fired based on some specific activities that happen. I'm trying to determine if I should create my own event handling system using the Java EventObject with custom listeners similar to Java AWT Or should I use a JMS implementation? I was considering either apache's Qpid or ActiveMQ solution. I'm exploring these options at the moment and was wondering if anyone has experience with Qpid or ActiveMQ and can offer some advise (e.g., pros, cons to consider, etc) Also, if anyone has any suggestions for building a simple event handling system... if it's even worth while to consider this over a JMS based solution.

  • Is MonoTouch worth the cost or should I just learn Objective-C?

    - by jamesaharvey
    After sitting through a session today on Mono at a local .Net event, the use of MonoTouch was 'touched' upon as an alternative for iPhone development. Being very comfortable in C# and .Net, it seems like an appealing option, despite some of the quirkiness of the Mono stack. However, since MonoTouch costs $400, I'm somewhat torn on if this is the way to go for iPhone development. Anyone have an experience developing with MonoTouch and Objective-C, and if so is developing with MonoTouch that much simpler and quicker than learning Objective-C, and in turn worth the $400?

  • Android layout with 2 evenly spaced Buttons

    - by Rpond
    I have this layout that works correctly, a relative layout with a text view and two buttons spaced evenly below it. <RelativeLayout android:id="@+id/entrypopup" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="5px" android:visibility="gone" android:layout_below="@+id/ad" android:background="#80000000"> <TextView android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Entry Popup..." android:textColor="#ffffffff" android:textSize="20sp" /> <TableLayout android:id="@+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/title"> <TableRow android:layout_weight="1"> <Button android:id="@+id/buttonVisit" android:text="View" android:layout_height="fill_parent" android:layout_width="0dip" android:layout_weight="1"/> <Button android:id="@+id/buttonCancel" android:text="Cancel" android:layout_width="0dip" android:layout_weight="1" android:layout_height="fill_parent"/> </TableRow> </TableLayout> </RelativeLayout> But running layoutopt it says that "this TableRow layout or its TableLayout parent is possible useless". Is there a way to do this layout then without the tables?

  • Neural Network: Handling unavailable inputs

    - by Mike
    Hopefully the last NN question you'll get from me this weekend, but here goes :) Is there a way to handle an input that you "don't always know"... so it doesn't affect the weightings somehow? Soo... if I ask someone if they are male or female and they would not like to answer, is there a way to disregard this input? Perhaps by placing it squarely in the centre? (assuming 1,0 inputs at 0.5?) Thanks

  • Obtaining IP addresses in Bittorrent

    - by Legend
    I am trying to get a list of IP addresses serving or downloading a file. What I did was to contact a tracker like openbittorrent.com to get the following (as part of the scrape file): B%00%00%0C%5F%B1%B1l%CAGa%84S%CB%B0%9BG%84%3BE:0:1 Now, the long string in the beginning is the info hash. As a next step, I did this: http://tracker.sometracker.com/announce?info_hash=B%00%00%0C%5F%B1%B1l%CAGa%84S%CB%B0%9BG%84%3BE It gave me back the following. So far so good. The message contained this: d8:completei0e10:downloadedi0e10:incompletei2e8:intervali1931e12:min intervali965e5:peers12:U????????^@^@e Can someone tell me what should I be doing after this to get the IP addresses currently serving the file or downloading it?

  • Scale transform in xaml (in a controltemplate) on a button to perform a "zoom"

    - by Matt B
    Hi all, I've got a button with an image in it and it's being styled by the following: <ControlTemplate x:Key="IconButton" TargetType="Button"> <Border> <ContentPresenter Height="80" Width="80" /> </Border> <ControlTemplate.Triggers> <EventTrigger RoutedEvent="Button.Click"> <BeginStoryboard> <Storyboard TargetProperty="Opacity"> <DoubleAnimation From="1" To="0.5" Duration="0:0:0.5" /> <DoubleAnimation From="0.5" To="1" Duration="0:0:0.5" /> </Storyboard> </BeginStoryboard> </EventTrigger> <EventTrigger RoutedEvent="Mouse.MouseEnter"> <BeginStoryboard> <Storyboard TargetProperty="Width"> <DoubleAnimation From="80" To="95" Duration="0:0:0.2" /> </Storyboard> </BeginStoryboard> </EventTrigger> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Cursor" Value="Hand"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> Button is as follows: <Button Template="{StaticResource IconButton}" Name="btnExit"> <Image Source="Images/Exit.png" /> </Button> The problem is that the width doesn't change when my mouse goes over. (Or at least - the width of the image does not...) I believe there is a "scale" transform I can use to enlarge the button and all it's contents? how would I do that here...? Thanks.

  • Extract data from specific range of cells in multiple worksheet in multiple files.

    - by Michele
    Extract data from specific range of cells(always the same cells) in multiple worksheet in multiple files. 1 file=1 day. I have 6 technicians each day of the week, Monday thru Friday. So, 5 files with 6 worksheets. I have entered specific info in specific cells of every work sheet. The range is constant(the same address in EVERY worksheet in every file.) So, I need a formula to extract and calculate the data in the given range and dump it into another spreadsheet. I can forward an example a file if it will help anyone to answer my question. Or more explanation if necessary is available upon request. JUST PLEASE SOMEBODY HELP ME!!!!! Thank you all in advance. Regards, Michele

  • It is not quiet....

    - by Anthony Shorten
    You may of noticed that the blog entries have been not so frequent lately. I have been extremely busy with putting the final touches on the release of the next generation of our products. It is an exciting time for me to see the release of new functionality from start to finish for the first time becoming a Product Manager (good to see one's designs actually implemented). Once the next generation of the products have been released there will be a flood of entries outlining all the new and exciting features. Watch the skies....

  • Did You Know: What do you know that isn't so?

    - by Kalen Delaney
    You know what they say… it's not what you don't know that will hurt you, it's what you know that isn't so! In other words, your misconceptions. Or, as Paul Nielson calls them in his SQL Server Bible … MYTHconceptions. Some misconceptions come from misunderstanding of complex information, or from misinterpreting your own results, and assuming we can generalize behavior from one particular situation. Since I teach advanced classes to students with lots of SQL Server experience, I actually see a lot...(read more)

  • Three Buckets of Knowledge

    - by BuckWoody
    As I learn more and more about SQL Server every day, I divide up my information into three “buckets”: Concepts In the first bucket are the general concepts about the topic. What is it? What does it do (or sometimes, what is is supposed to do?) How does one operation flow to another? For this information I use books, magazine articles and believe it or not – Wikipedia. I don’t always trust that last source, but I do use it to see how others lay out their thoughts around a concept. I really like graphical charts that show me the process flow if I can get it, and this is an ideal place for a good presentation. In fact, this may be the only real use for a presentation – I’ll explain what I mean in a moment. Reference The references for a topic include things like Transact-SQL (T-SQL) syntax, or the screen layout on a panel, things like that. Think Dictionary. The only reference I trust for this information is Books Online – presentations are fine, but we’re talking about a dictionary. Ever go to a movie that just reads through a dictionary? Me neither. But I have gone to presentations where people try to include tons of reference materials in their slides. Even if you give me the presentation material later, it’s not really a searchable, readable medium. How To A how-to for me is an example, or even better, a tutorial about an example. Whatever it is shows me a practical use for the concepts and of course involves the syntax. The important thing here is that you need to be able to separate out the example the person is showing you from the stuff you need to know. I can’t tell you how many times folks have told me, “well, sure, if yours is red then that works. But mine is blue.” And I have to explain, “then use “blue” for the search word here.” You get the idea. No one will do your work for you – the examples are meant as a teaching tool only. I accept that, learn what I can, and then run off to create my own thing. You might think a How To works well in a presentation, and it does, for the most part. For a complex example or tutorial, I still prefer the printed word (electronic if possible) so that I can go over the example multiple times, skip around and so on.   The order here isn’t actually that important. Most of the time I start with a concept, look at an example, and then read the reference material. But sometimes I look up an example, read a little of concepts and then check the reference. The only primary thing I try to enforce is to read something from each of them. It’s dangerous to base your work on any single example, reference or concept.  Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • MS Word Macro - Numeric field insertion with automatic calculation at end of page

    - by Will
    Hi, I am trying to duplicate a feature that exists in Multimate (Ashton Tate) word processor. Yes, the one that hasnt been supported for 20 years! If I can duplicate this one feature I can get all the users off MM and onto Word. The documents they create are billing documents. they consist of a descriptive paragraph of any length on the left side of the page, and a billing amount at the end of the paragraph over on the right hand side, like this (excuse the imperfect formatting).... +-----------------whole page--------------------+ |                                                                    | |    pppp-para 1-pppppppppp                   | |    p                                         p                   | |    p                                         p                   | |    p                                         p                   | |    p                                         p                   | |    p                                         p                   | |    p                                         p                   | |    pppppppppppppppppppp      $$$$$  | |                                                                    |  |                                                                    |  |    pppp-para 2-pppppppppp                   | |    p                                         p                   | |    p                                         p                   | |    p                                         p                   | |    p                                         p                   | |    p                                         p                   | |    p                                         p                   | |    pppppppppppppppppppp      $$$$$  | |                                                                    |  |                                                                    |  |                             etc                                  | +-----------------------------------------------------+ some of these bills can be a few hundred pages and have a dozen or so paragraphs on each page, which is why none of the users will leave MM until this efficient little feature can be duplicated. The thing that MM does really easily is that there is a function key that they can press at any time that will - - jump the cursor from the paragraph they are writing over to the right hand side - create a numeric field - allow them to enter a number into the numeric field - return them to the left hand side to start a new paragraph What MM also does is automatically total the numeric fields on each page and create a subtotal in the page footer. it also creates a total for the entire document and puts this in the footer of the last page. I would like to duplicate this feature in word with a macro, but have no idea where to start. Any suggestions or code would be great, thanks, will.

  • C++ constant reference lifetime

    - by aaa
    hello I have code that looks like this: class T {}; class container { const T &first, T &second; container(const T&first, const T & second); }; class adapter : T {}; container(adapter(), adapter()); I thought lifetime of constant reference would be lifetime of container. However, it appears otherwise, adapter object is destroyed after container is created, leading dangling reference. What is the correct lifetime? how to correctly implement binding temporary object to class member reference? Thanks

  • Strange constructor

    - by Bilthon
    Well, I'm gonna be pretty straightforward here, I just have a piece of code in c++ which I'm not sure I really understand and need some help with. Ok, to simplify lets just say I have a class that is defined like this: (the real class is a little bit more complicated, but this is what matters) class myClass : public Runnable { Semaphore *m_pMySemaphore; __Queue<Requests> *m_pQueue; Request m_Request; VetorSlotBuffer *m_vetorSlotBuffer; } Up to here nothing is wrong, myClass is just a regular class which has 3 members that actually are pointers to other classes and an object of the class Request, the implementation of those classes not being important for my point here. Then when this person implemented the constructor for myClass he or she did this: myClass::myClass() : m_pMySemaphore(0), m_pQueue(0), m_vetorSlotBuffer(0) { } It's pretty evident that those three variables are treated like that by the constructor because they are pointers, am I right? but what kind of syntax is that? am I setting the pointers to null by doing that? I've seen a little bit of c++ already but never found something like that. And secondly, what's the deal with the ":" after the constructor declaration? that I've seen but never took the time to investigate. Is this like an inner class or something? Thank you very much in advance. Nelson R. Perez

  • Setting Xcode's target to iPhone NOT iPad

    - by Garry
    I just upgraded to iPhone SDK 3.2 Beta 4. Since doing so, I have not been able to get the app to launch in the iPhone simulator - it keeps launching in the iPad simulator. I have tried option-clicking the drop-down menu in the top left-corner of Xcode and setting 'Active Executable' to iPhone simulator 3.1.3 but it keeps going back to iPad simulator instead. What gives? I have no interest in my app running on the iPad and I don't want to test it in the 2X mode in the simulator. Thanks,

  • Inter process communication C# <--> C++ for game debugging engine.

    - by Andy
    I am working on a debugger project for a game's scripting engine. I'm hoping to write the debugger's GUI in C#. The actual debugging engine, however, is embedded in the game itself and is written in a mixture of C, C++, and assembly patches. What's the best way to handle communication between the debugger GUI and the debugging engine? The two will be running in separate processes. Thanks! Andy

  • CoreData is saving model without the save: method being called

    - by chris
    I have a list of items with a plus button in the navigation bar that opens up a modal window containing a table of the models attributes, that displays a form when the table items are clicked (pretty standard form style). For some reason if I click the plus button to open the form to create a new model, then immediately click the done button, the person model is saved. The action linked to the done button does nothing but call on a delegate method notifying the personListViewController to close the window. The apple docs do state that the model is not saved after calling the insertNewObjectForEntityName: ... Simply creating a managed object does not cause it to be saved to a persistent store. The managed object context acts as a scratchpad. I am at a lost to why this is happening, but every time I click the done button I have a new blank item in the original tableView. I am using SDK v3.1.3 // PersonListViewController - open modal window - (void)addPerson { // Load the new form PersonNewViewController *newController = [[PersonNewViewController alloc] init]; newController.modalFormDelegate = self; [self presentModalViewController:newController animated:YES]; [newController release]; } // PersonFormViewController - (void)viewDidLoad { [super viewDidLoad]; if ( person == nil ) { MyAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; self.person = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:appDelegate.managedObjectContext]; } ... UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; } - (IBAction) done { [self.modalFormDelegate didCancel]; } // delegate method in the original listViewController - (void) didCancel { [self dismissModalViewControllerAnimated:YES]; }
