  • How can I get the same strstream functionality now that's deprecated?

    - by chila
    I use to write code like this: void fun(char *buff, unsigned size) { std::strstream str(buff, size); str << "hello world: " << 5; } so I can use stream output over an arbitrary buffer. I've found this technique both efficient (no allocations) and useful (streams!). Now that std::strstream is deprecated, how can I get the same speed+flexibility that I can get with this code?

    - by Boone
    I am using the Silverlight sdk for Bing Maps. I have my map, I have my PushPins all mapped out. Now I want to disable the user from zooming out so far they see the whole world and keep it constricted to the just the US. It would be nice if there was something simple like Map.MaxZoom but there is not. Any help?

  • Rails 3 Initializers: No such file to load

    - by waveslider
    I am trying to use the Sunlight API gem with a Rails project. I have installed the gem and can successfully use it from irb. However, when I put the require statement (require 'sunlight') in sunlight.rb in config/initializers, I get the following error: /opt/local/lib/ruby/gems/1.8/gems/activesupport-3.0.0.beta3/lib/active_support/dependencies.rb:209:in `require': no such file to load -- sunlight (LoadError) I checked the permissions on the gems directory, and it is world readable/executable. Here is the code from sunlight.rb: require 'rubygems' require 'sunlight' Sunlight::Base.api_key = 'bb7b775755054c54aa9715d202f6785c'

    I've added a UIAppFont to my plist, and, happily, am able to write a custom font to my display. Now, if I had to display this custom font in a very large size with a yellow outline and purple in the middle- how in the world would I achieve that??

  • Why doesn't line-height work on FF/3.5.8(Mac)?

    - by Znarkus
    I can't get line-height on a text input to work on Firefox 3.5.8/(Mac). Works flawlessly on: IE6 IE7 IE8 FF3.6/PC FF3.6/Mac Safari Test code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>asd</title> <link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/2.8.0r4/build/reset/reset-min.css" /> </head> <body> <input type="text" value="Hello" style="line-height:50px;height:50px;font-size:16px;" /> <input type="text" value="Hello" style="padding:17px 0;font-size:16px;" /> </body> </html> Is there an alternate solution or any idea how to fix this? Edit: Updated the test code, to compare line-height vs. padding technique. Padding works on all above browsers except IE8. Whaat? I can't test on FF/3.5.8 anymore, could someone please report the result from this browser on any plattform? I'm now thinking this is a Firefox 3.5.8 issue, plattform independent.

  • Javascript (JSON) Objects: Get Parent

    - by Dänu
    Hey Guys I got some question about nested javascript objects (is it me, google or is javascript quite poorly documented?). Now, I got the following (nested) object: obj: { subObj: { 'hello world' } }; next thing I do is to reference the subobject like this: var s = obj.subObj; now what I would like to do, is to get a reference to the object obj out of the variable s. Something like: var o = s.parent; Is this somehow possible?

  • Colorbox iFrame content not appearing in IE 8/9

    - by Rocketpig
    I'm using ColorBox to call a few informational modals on-screen and given the client's requirements, the best way to do this is via iFrames (not my first choice but whatever). Everything is working peachy in Chrome, FF, etc. but the iFrame content is not working in any version of IE. The modal wrapper appears but nothing is inside. This is what I've done so far: Changed the doctype to transitional and strict for IE. No dice. Removed the "iframe: true" and replaced it with HTML "Hello". That worked fine and "Hello" appeared in the Colorbox modal. I've removed all stylesheets from the header. No luck so it's not a CSS issue. Just to be sure, I rolled back my JQuery library to 1.6.2 from 1.8.2. Nothing there, either. Any help would be appreciated. This is aggravating. Some code: $(function () { $(".modal-large").colorbox({iframe:true, innerWidth:580, innerHeight:500}); }) HTML: <div class="top-droptext"><a class="modal-large" href="modal/serviceproviderinfo.html">Update Password</a></div>

  • C# 'could not found' existing method

    - by shybovycha
    Greetings! I've been fooling around (a bit) with C# and its assemblies. And so i've found such an interesting feature as dynamic loading assemblies and invoking its class members. A bit of google and here i am, writing some kind of 'assembly explorer'. (i've used some portions of code from here, here and here and none of 'em gave any of expected results). But i've found a small bug: when i tried to invoke class method from assembly i've loaded, application raised MissingMethod exception. I'm sure DLL i'm loading contains class and method i'm tryin' to invoke (my app ensures me as well as RedGate's .NET Reflector): The main application code seems to be okay and i start thinking if i was wrong with my DLL... Ah, and i've put both of projects into one solution, but i don't think it may cause any troubles. And yes, DLL project has 'class library' target while the main application one has 'console applcation' target. So, the question is: what's wrong with 'em? Here are some source code: DLL source: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ClassLibrary1 { public class Class1 { public void Main() { System.Console.WriteLine("Hello, World!"); } } } Main application source: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Assembly asm = Assembly.LoadFrom(@"a\long\long\path\ClassLibrary1.dll"); try { foreach (Type t in asm.GetTypes()) { if (t.IsClass == true && t.FullName.EndsWith(".Class1")) { object obj = Activator.CreateInstance(t); object res = t.InvokeMember("Main", BindingFlags.Default | BindingFlags.InvokeMethod, null, obj, null); // Exception is risen from here } } } catch (Exception e) { System.Console.WriteLine("Error: {0}", e.Message); } System.Console.ReadKey(); } } } UPD: worked for one case - when DLL method takes no arguments: DLL class (also works if method is not static): public class Class1 { public static void Main() { System.Console.WriteLine("Hello, World!"); } } Method invoke code: object res = t.InvokeMember("Main", BindingFlags.Default | BindingFlags.InvokeMethod, null, null, null);

  • Converting WAR to EAR and other Glassfish stories

    - by Random
    Hello! I am really new in this so I hopefully don't make any terrible mistake. I apologize before hand if I have. In my project I was using tomcat and deploying WAR files. But now some bosses wants to deploy EAR files. So there we go. I first downloaded Glassfish (don't know if it's the apropiate application server for a newbie like me), instaled it and all (I even deployed the hello.war in the autodeploy _< ). Then prepared an EAR file. From what I know, I just need to create an Enterprise Application Project in Eclipse and add to the module my war file. This changes the application.xml file automatically (thanks eclipse project!). So I exported it to an EAR file and uploaded it to the glassfish server. Wonders of wonders, it doesn't work. I also tried deploying the old WAR file in this new shiny glassfish but it goes on http-404 not found error. The glassfish seems to say that my project is not in ~/domains/domain1/docroot. By the way I am using windows and I am aware of some problems between glassfish and windows due to some updating open files or such. So I have to questions: First, Am I doing the EAR package correctly? Second, Do I need to do some especial configuration to the glassfish server to deploy EAR and WAR files? Thanks!

  • how to use cherrpy built in data storage

    - by user291071
    Ok I have been reading the cherrypy documents for sometime and have not found a simple example yet. Let say I have a simple hello world site, how do I store data? Lets say I want to store a = 1, and b =2 to a dictionary using cherrypy. The config files are confusing as hell. Anyone have very simple example of storing values from a simple site in cherrypy?

  • jtable update data not visible

    - by Thomas n
    I am running into a problem similar to what I have read here about inserted data and added data not showing up on jtable. I have tried repaint() and revalidate(), but to no avail. Basically, I have two classes say A and B. A calls a function in class B to add a row of data to the table. Here is the code.(By the way I am using Netbeans 7.1.2 to add a table and then add some code to handle the update.) public void callUpdateTable(){ DefaultTableModel myModel = (DefaultTableModel)jTable1.getModel(); DateFormat dateFormate = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss"); Object[] str = new Object[3]; Date date = new Date(); str[0] = dateFormate.format(date); str[1] = "Robot"; str[2] = "hello"; // myModel.addRow(str); myModel.insertRow(1, str); myModel.setValueAt("Hello", 1, 2); System.out.println("count = " + myModel.getValueAt(1, 2)); jTable1.repaint(); } The funny thing is on system print it prints out the value at the cell(1,2) I set the value, but doesn't show up on the table. Thank you for your help.

  • Good starting point to learn regular expressions.

    - by Jeremy Rudd
    I'm good at learning new languages and platforms, though whenever I try to learn Reg Ex I cannot make sense of it. I once even used the Regular Expression Designer to try and put some together. What's a good starting point to understanding what looks like the only rocket-science programming language in the world? Links to articles, books or anything else that could help me get my grounding would be appreciated.

  • JPA - Can I create an Entity class, using an @DiscriminatorValue, that doesn't have its own table?

    - by DaveyDaveDave
    Hi - this is potentially a bit complex, so I'll do my best to describe my situation - it's also my first post here, so please forgive formatting mistakes, etc! I'm using JPA with joined inheritance and a database structure that looks like: ACTION --------- ACTION_ID ACTION_MAPPING_ID ACTION_TYPE DELIVERY_CHANNEL_ACTION -------------------------- ACTION_ID CHANNEL_ID OVERRIDE_ADDRESS_ACTION -------------------------- ACTION_ID (various fields specific to this action type) So, in plain English, I have multiple different types of action, all share an ACTION_MAPPING, which is referenced from the 'parent' ACTION table. DELIVERY_CHANNEL_ACTION and OVERRIDE_ADDRESS_ACTION both have extra, supplementary data of their own, and are mapped to ACTION with a FK. Real-world, I also have a 'suppress' action, but this doesn't have any supplementary data of its own, so it doesn't have a corresponding table - all it needs is an ACTION_MAPPING, which is stored in the ACTION table. Hopefully you're with me so far... I'm creating a new project from scratch, so am pretty flexible in what I can do, but obviously would like to get it right from the outset! My current implementation, which works, has three entities loosely defined as follows: @Entity @Table(name="ACTION") @Inheritance(strategy=InheritanceType.JOINED) @DiscriminatorValue("SUPPRESS") public class Action @Entity @Table(name="DELIVERY_CHANNEL_ACTION") @DiscriminatorValue("DELIVERY_CHANNEL") public class DeliveryChannelAction extends Action @Entity @Table(name="OVERRIDE_ADDRESS_ACTION") @DiscriminatorValue("OVERRIDE_ADDRESS") public class OverrideAddressAction extends Action That is - I have a concrete base class, Action, with a Joined inheritance strategy. DeliveryChannelAction and OverrideAddressAction both extend Action. What feels wrong here though, is that my Action class is the base class for these two actions, but also forms the concrete implementation for the suppress action. For the time being this works, but at some point more actions are likely to be added, and there's every chance that some of them will, like SUPPRESS, have no supplementary data, which will start to get difficult! So... what I would like to do, in the object model world, is to have Action be abstract, and create a SuppressAction class, which is empty apart from having a @DiscriminatorValue("SUPPRESS"). I've tried doing exactly what is described above, so, changing Action to: @Entity @Table(name="ACTION") @Inheritance(strategy=InheritanceType.JOINED) public abstract class Action and creating: @DiscriminatorValue("SUPPRESS") public class SuppressAction extends Action but no luck - it seems to work fine for DeliveryChannelAction and OverrideAddressAction, but when I try to create a SuppressAction and persist it, I get: java.lang.IllegalArgumentException: Object: com.mypackage.SuppressAction[actionId=null] is not a known entity type. at org.eclipse.persistence.internal.sessions.UnitOfWorkImpl.registerNewObjectForPersist(UnitOfWorkImpl.java:4147) at org.eclipse.persistence.internal.jpa.EntityManagerImpl.persist(EntityManagerImpl.java:368) at com.mypackage.test.util.EntityTestUtil.createSuppressAction(EntityTestUtil.java:672) at com.mypackage.entities.ActionTest.testCRUDAction(ActionTest.java:27) which I assume is down to the fact that SuppressAction isn't registered as an entity, but I don't know how I can do that, given that it doesn't have an associated table. Any pointers, either complete answers or hints for things to Google (I'm out of ideas!), most welcome :) EDIT: to correct my stacktrace.

  • [VB.Net] Typecasting generic parameters.

    Hello world! Using the following code: Function GetSetting(Of T)(ByVal SettingName As String, ByRef DefaultVal As T) As T Return If(Configuration.ContainsKey(SettingName), CType(Configuration(SettingName), T), DefaultVal) End Function Yields the following error: Value of type 'String' cannot be converted to 'T'. Any way I could specify that in all cases, the conversion will indeed be possible (I'm basically getting integers, booleans, doubles and strings). Thanks!

  • How to create "floating TextViews" in Android?

    - by Sotapanna
    Hi stackies, I'm programmatically putting various TextViews into a LinearLayout with a horizontal orientation. After 2h of research I couldn't find out how to tell Android not to squeeze all the TextViews in one line but instead to "float" non-fitting TextViews into the next line. I know there isn't something like actual "lines" in a LinearLayout, but how can I tell the TextViews to actually behave like floating DIVs from the HTML world? Thanks alot! Be well S.

However, I know in all "real world" situations, I will be connecting to a dedicated server that will hold the site. So here is my question: what are the pros and cons of developing on the machine I use vs running the website on a separate server?

  • Passing function-specific variables

    - by Simon Carlson
    Say I got two functions that looks like this: function main(Index) { doStuff(); } function doStuff() { if(Index == 1) { document.write("Hello world!") } } And some HTML: <input type="button" value="Click me" onclick="main(1)" /> I realize this is a very stupid way to use function-specific variables and such, but it's just out of curiosity. So is it possible to pass the variable Index from the main function to the doStuff function?
