  • How can find out the system default currency symbol on BlackBerry?

    - by ageektrapped
    I have a need to display a currency value in my application. There doesn't seem to be an easy way to do this with the RIM API, so I'm reduced to creating my own solution (a common refrain for BlackBerry development, unfortunately) Currently I'm using the Formatter class, from javax.microedition.locale like so protected String formatResult(double result) { try { Locale l = Locale.getDefaultForSystem(); Formatter formatter = new Formatter(l.toString()); return formatter.formatCurrency(result); } catch (UnsupportedLocaleException e) { return "This fails for the default locale because BlackBerry sucks"; } } I always hit the catch block in the simulator. Since this doesn't work by default on the simulator, I'm hesitant to put it in the application. So I have two questions: Can anyone tell me if the above solution is the way to go? And how to fix it, of course. Is there a way I can retrieve the currency symbol for the current locale programmatically so I can format myself?

  • Best .NET Solution for Frequently Changed Database

    - by sestocker
    I am currently architecting a small CRUD applicaton. Their database is a huge mess and will be changing frequently over the course of the next 6 months to a year. What would you recommend for my data layer: 1) ORM (if so, which one?) 2) Linq2Sql 3) Stored Procedures 4) Parametrized Queries I really need a solution that will be dynamic enough (both fast and easy) where I can replace tables and add/delete columns frequently. Note: I do not have much experience with ORM (only a little SubSonic) and generally tend to use stored procedures so maybe that would be the way to go. I would love to learn Ling2Sql or NHibernate if either would allow for the situation I've described above.

  • Is there any injection vunerability in the body of an email?

    - by Brett
    Hey guys..... AFAIK there is only a vulnerability within the HEADERS of an email when using user data correct? I am using the below function to sanitize my data, however I have some textarea fields on the page & hence these may contain linebreaks.. so was wondering if that user data is only going to be put in the body of the email, can it not bother with being sanitized - apart from stripping html of course? Here is the function: function is_injected($str) { $injections = array('(\n+)', '(\r+)', '(\t+)', '(%0A+)', '(%0D+)', '(%08+)', '(%09+)' ); $inject = join('|', $injections); $inject = "/$inject/i"; if (preg_match($inject,$str)) { return true; } else { return false; } } As a side note, surprised there wasn't currently a tag for mail-injection / email-injection. Thanks!

  • Manage widgets from page edit screen

    - by Greenie
    Hi there. I'm looking to find a way to integrate the widget control area into the page edit screen. For the site I'm making it would be perfect with the same drag and drop functionality. I want a list of the available widgets that I can drag and drop into the page widget area. The widgets will then only be shown on that particular page. I've looked through the wp-admin/widgets.php file and tried to use some code from there. I even tried just including widgets.php at the end of the post.php (which is basically what I want, but of course gave me funny results). Please don't suggest plug-ins like Widget Context or Widget Logic. Those are my fallback if I cant do this :) So I would like ideas and/or input on how to accomplish this. Preferably I'd like to do it in the functions.php file, or in a plug-in.

  • Classic asp paging and session state

    - by flavour404
    Hi, Working on a classic asp page that uses paging. The error I am having a problem with is this: Lets say that you have 5 pages returned in your record set and you are on page 2. You leave and come back, you then press the link for page 3, the trouble is your session has timed out. I don't know why this happens but the page is reloaded, but the session check is bypassed and of course when the page attempts to retrieve the record set the session variables are now empty so I am getting a message stating: error near ',' line 1, because now the query is defunct. How do I get around this? Thanks, Ron.

  • Wicket and a rich ajax website: easiest way to do it?

    - by Sherkaner
    I want to use Wicket to build an application, but I have some designers that would like to write/maintain the javascript, and they basically expect 1 JS-segment per page, and a global JS-file. I think the most natural way to add javascript in wicket is to add it per component (not per page), which would create problems for those designers (fractioned javascript, and having to write it in java-files). Is there a better way to solve this? (of course, I expect things to work after a partial refresh.) And a second (related) thing they'd like (and I'd like actually) is the possibility to request information in JSON-format through a static link , is this possible in Wicket?

  • How to create unique user key

    - by Grayson Mitchell
    Scenario: I have a fairly generic table (Data), that has an identity column. The data in this table is grouped (lets say by city). The users need an identifier in order for printing on paper forms, etc. The users can only access their cites data, so if they use the identity column for this purpose they will see odd numbers (e.g. a 'New York' user might see 1,37,2028... as the listed keys. Idealy they would see 1,2,3... (or something similar) The problem of course is concurrency, this being a web application you can't just have something like: UserId = Select Count(*)+1 from Data Where City='New York' Has anyone come up with any cunning ways around this problem?

  • How can I relocate to a new repository address with TortoiseSVN?

    - by Jesse McGrew
    I have a working copy checked out from: https://oldserver/svn/myproject/branches/mybranch The server address has changed (actually, the repo was copied over to a new server) so I want to relocate my working copy to the new address: https://newserver/svn/myproject/branches/mybranch Note that only the address changed, not the path. But if I type that URL in TortoiseSVN's "Relocate" dialog box, I get the error "'https://newserver/svn/myproject/branches/mybranch' is not the root of the repository" ... well, of course it isn't, but so what? Then I thought maybe SVN wanted the repository root URL, so I tried giving it https://newserver/svn instead, but that produced the error "Relocate can only change the repository part of an URL". Are there any options besides backing up my changes and checking out a fresh WC from the new server?

  • Avoid stuck calling callback

    - by andlomba
    Hello all, This is a question about generic c++ event driven applications design. Lets assume that we have two threads, a "Dispatcher" (or "Engine"...) and a "Listener" (or "Client"...). Let's assume that I write the Dispatcher code, and release it as a library. I also write the Listener interface, of course. When the Dispatcher executes (after Listener registration) listenerInstance.onSomeEvent(); the event handling code will actually be executed by the Dispatcher thread, so if the person that implements the Listener writes something like void Listener::onSomeEvent() { while(true) ; } The Dispatcher will stuck forever. Is there a "plain old c++" (I mean no boost or libsigc++) way to "decouple" the two classes, so I can be sure that my Dispatcher will work fine whatever the Listeners does in the callbacks? bye and thanks in advance, Andrea

  • Best choice for off-site backup: dd vs tar

    - by plok
    I have two 1TB single-partition hard disks configured as RAID1, of which I would like to make an off-site backup on a third disk, which I am still to buy. The idea is to store the backup at a relative's house, considerably far away from my place, in the hope that all the information will be safe in the case of a global thermonuclear apocalypse. Of course, this backup would be well encrypted. What I still have to decide is whether I am going to simply tar the entire partition or, instead, use dd to create an image of the disks. Is there any non-trivial difference between these two approaches that I could be overlooking? This off-site backup would be updated no more than two or three times a year, in the best of the cases, so performance should not be a factor to be pondered at all. What, and why, would you use if you were me? dd, tar, or a third option?

  • Getting started developing for iPhone

    - by mikemoosey
    Hey all, quick question. My end goal is to start developing apps for the iPhone but my current skillset is pretty limited. I'm wondering how far back I should go back and where I should start as far as becoming familiar with coding before the iPhone SDK course on Lynda.com isn't something that makes my eyes glaze over. My experience: I taught myself html from the html for dummies book maybe 10 years ago, I've taken a dreamweaver class and built a few sites with it, and I've customized a self hosted Wordpress blog by playing with the php code. Any tips on where I should start if I want to head down the road toward developing for the iPhone? Thanks!

  • VS 2010 Error “Object reference not set to an instance of an object” when adding Service Reference f

    - by Andy
    I have a VS2010 (RTM) solution which contains: WCF Service project Console WCF client project Class project for DataContracts and members Class project for some simple classes I successfully added a service reference in the console client project and ran the client. I then did a long dev cycle repeatedly modifying the service then updating console service reference. I then changed the namespace and assembly names for the projects as well as the .cs using references and app.config. I of course missed some things as it would not build so I eventually removed the project references and the service reference, cleaned and built successfully. I then attempted to add the service reference again, it discovered it but threw the “Object reference not set to an instance of an object” when OK'ing. Fix in answer below...

  • Duplicate / Copy records in the same MySQL table

    - by Digits
    Hello, I have been looking for a while now but I can not find an easy solution for my problem. I would like to duplicate a record in a table, but of course, the unique primary key needs to be updated. I have this query: INSERT INTO invoices SELECT * FROM invoices AS iv WHERE iv.ID=XXXXX ON DUPLICATE KEY UPDATE ID = (SELECT MAX(ID)+1 FROM invoices) the proble mis that this just changes the ID of the row instead of copying the row. Does anybody know how to fix this ? Thank you verrry much, Digits //edit: I would like to do this without typing all the field names because the field names can change over time.

  • Fake Mouse (C# or C++)

    - by Hidden
    I need a way to fake that a mouse is connected. The problem: My HTPC (Windows 8) has no mouse connected and I wrote a program to simulate mouse input using my Xbox 360 Controller. This works just fine, the only problem is, that there is no cursor visible (I can move it, but I cant see it). My guess is, that Windows doesn't show a cursor when there is no mouse connected, so I need a way to pretend that a mouse is connected to the PC. Of course, if you know another way to make the cursor visible I would gladly take this solution as well. Regards, Hidden

  • How is executed a SendMessage from a different thread?

    - by Lorenzo
    When we send a message, "if the specified window was created by the calling thread, the window procedure is called immediately as a subroutine". But "if the specified window was created by a different thread, the system switches to that thread and calls the appropriate window procedure. Messages sent between threads are processed only when the receiving thread executes message retrieval code." (taken from MSDN documentation for SendMessage). Now, I don't understand how (or, more appropriately, when) the target windows procedure is called. Of course the target thread will not be preempted (the program counter is not changed). I presume that the call will happen during some wait function (like GetMessage or PeekMessage), it is true? That process is documented in detail somewhere?

  • How much faster are register based architectures than stack architectures?

    - by drozzy
    Studying compilers course, I am left wondering why use registers at all. It is often the case that the caller or callee must save the register value and then restore it. In a way they always end up using the stack anyway. Is creating additional complexity by using registers really worth it? Excuse my ignorance. Update: Please, I know that registers are faster than RAM and other types of cache. My main concern is that one has to "save" the value that is in the register and the "restore" it to. In both cases we are accessing some kind of cache. Would it not be better to use cache in the first place?

  • Is it possible to retrieve only a single property from a CSS class?

    - by werner5471
    Example CSS File: .testClass { color: black; background: red; } Now in an HTML file, I would like to have something like <span class="testClass:color">Text in black but without red background</span> to only apply the color property of that class. Is there a way to do this? The purpose behind it (for people asking themselves "Why the hell would he want that, that's not clean CSS usage!") is that I use jQuery UI themes, and I would like the entire page to fit a theme upon change. As not all kinds of elements (e.g. the color of a link) are covered by those themes, in those cases I would like to "steal" the color property (but not more) of some other CSS class of the jQuery UI theme. If there is another way to do this, of course I'm glad to hear it as well!

  • Google Play Distributing to Phones only

    I read the guide Distributing to Specific Screens and i tried both <compatible-screens android:smallScreens="false" android:normalScreens="false" android:largeScreens="true" android:xlargeScreens="true"/> and <supports-screens android:smallScreens="false" android:normalScreens="false" android:largeScreens="true" android:xlargeScreens="true"/> even combined (iknow... i know... :D) But i can't seem to be able to limit my app from showing up in searches from my tablet (and of course it also installs) The reverse setting works though.. <supports-screens android:smallScreens="false" android:normalScreens="false" android:largeScreens="true" android:xlargeScreens="true"/> my phone appears incompatible with the tablet version of the APK. What gives? is there something i'm not getting in the way that Google play filters using the Manifest?

  • jQuery hover() event on div element within a button element

    - by jakeisonline
    I can't seem to get jQuery to notice the div within the following markup <button class="button submit positive right" id="omnisubmit" type="submit"> <div class="label">Submit</div> <div class="controller">&nbsp;</div> </button> And here is the jQuery I'm currently using: $("button#omnisubmit div.controller").hover(function () { console.log("Hover..."); }); However, jQuery doesn't seem to pick up when the mouse is hovering over that div, $("button#omnisubmit div.controller").hover( works correctly, of course. I have a feeling it's because putting divs inside buttons may not be standard HTML?

  • Using TDD: "top down" vs. "bottom up"

    - by Christian Mustica
    Since I'm a TDD newbie, I'm currently developing a tiny C# console application in order to practice (because practice makes perfect, right?). I started by making a simple sketchup of how the application could be organized (class-wise) and started developing all domain classes that I could identify, one by one (test first, of course). In the end, the classes have to be integrated together in order to make the application runnable, i.e. placing necessary code in the Main method which calls the necessary logic. However, I don't see how I can do this last integration step in a "test first" manner. I suppose I wouldn't be having these issues had I used a "top down" approach. The question is: how would I do that? Should I have started by testing the Main() method? If anyone could give me some pointers, it will be much appreciated.

  • Can I use MFC objects in STL containers?

    - by Jesse Stimpson
    The following code doesn't compile for me in MSVC2005: std::vector<CMenu> vec(10); CMenu is an MFC menu object (such as a context menu). Through some testing I learned that CMenu does not have a public copy constructor. To do what I wanted to do, I needed to use a dynamic array. CMenu* menus = new CMenu[10]; // ... delete [] menus; Of course, now I've lost all the benefits of using an STL container. Do I have any other options?

  • Do I really have to call Focus in OnMouseDown of my custom Control?

    - by Thomas
    I'm implementing a custom control that inherits from Control. I want it to be focusable (it's a kind of list box). In the constructor, I do SetStyle(ControlStyles.Selectable, true); I can now use Tab to navigate to the control. However, when the control receives a mouse click, it does not automatically claim focus. I can work around this, of course: protected override void OnMouseDown(MouseEventArgs e) { Focus(); base.OnMouseDown(e); } But this feels like a kludge that should not be necessary. Is this really the way to go? Or is there some way to tell Control to claim focus automatically when it receives a mouse click?

  • App Engine - Save response from an API in the data store as file (blob)

    - by herrherr
    Hi there, I'm banging my head against the wall with this one: What I want to do is store a file that is returned from an API in the data store as a blob. Here is the code that I use on my local machine (which of course works due to an existing file system): client.convertHtml(html, open('html.pdf', 'wb')) Since I cannot write to a file on App Engine I tried several ways to store the response, without success. Any hints on how to do this? I was trying to do it with StringIO and managed to store the response but then weren't able to store it as a blob in the data store. Thanks, Chris
