  • Building Boost with LSB C++ Compiler

    - by Alex Farber
    I want to build my program with LSB C++ Compiler from the Linux Standard Base http://www.linuxfoundation.org/collaborate/workgroups/lsb. Program depends on the Boost library, built with gcc 4.4 version. Compilation fails. Is it possible to build the Boost library with LSB C++ Compiler? Alternatively, is it possible to build the Boost library with some old gcc version, what version is recommended? My final goal is to get my executable and third-party Boost libraries running on most Linux distributions. Generally, what can be done to get better binary compatibility for Linux distributions, developing C++ closed-source application depending on the Boost library?

  • Multiple usage of MenuItems declared once (WPF)

    - by Alex Kofman
    Is it possible in WPF to define some menu structure and than use it in multiple contexts? For example I'd like to use a set of menu items from resources in ContextMenu, Window's menu and ToolBar (ToolBar with icons only, without headers). So items order, commands, icons, separators must be defined just once. I look for something like this: Declaration in resources: <MenuItem Command="MyCommands.CloneObject" CommandParameter="{Binding SelectedObject}" Header="Clone"> <MenuItem.Icon> <Image Source="Images\Clone.png" Height="16" Width="16"></Image> </MenuItem.Icon> </MenuItem> <MenuItem Command="MyCommands.RemoveCommand" CommandParameter="{Binding SelectedObject}" Header="Remove"> <MenuItem.Icon> <Image Source="Images\Remove.png" Height="16" Width="16"></Image> </MenuItem.Icon> </MenuItem> <Separator/> <MenuItem Command="MCommands.CreateChild" CommandParameter="{Binding SelectedObject}" Header="Create child"> <MenuItem.Icon> <Image Source="Images\Child.png" Height="16" Width="16"></Image> </MenuItem.Icon> </MenuItem> Usage: <ToolBar MenuItems(?)="{Reference to set of items}" ShowText(?)="false" /> and <ContextMenu MenuItems(?)="{Reference to set of items}" />

  • Log information inside a JUnit Suite

    - by Alex Marinescu
    I'm currently trying to write inside a log file the total number of failed tests from a JUnite Suite. My testsuite is defined as follows: @RunWith(Suite.class) @SuiteClasses({Class1.class, Class2.class etc.}) public class SimpleTestSuite {} I tried to define a rule which would increase the total number of errors when a test fails, but apparently my rule is never called. @Rule public MethodRule logWatchRule = new TestWatchman() { public void failed(Throwable e, FrameworkMethod method) { errors += 1; } public void succeeded(FrameworkMethod method) { } }; Any ideas on what I should to do to achieve this behaviour?

  • RSA key length and export limitations

    - by Alex Stamper
    I know, there are a lot of limitations to the length of used key (import and export limitations for nearly each country). Usually, it varies from 64 to 256 bits. To use more bits, it is obligatory to ask permission from authorities. But it is recommended to use 1024 bits keys for RSA as minimum! Does it mean that I cannot just use RSA without any problems with law and so on?

  • Setting minOccurs="0" (not required) on web service parameters of type int

    - by Alex Angas
    I have an ASP.NET 2.0 web method with the following signature: [WebMethod] public QueryResult[] GetListData( string url, string list, string query, int noOfItems, string titleField) I'm running the disco.exe tool to generate .wsdl and .disco files from this web service for use in SharePoint. The following WSDL for the parameters is being generated: <s:element minOccurs="0" maxOccurs="1" name="url" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="list" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="query" type="s:string" /> <s:element minOccurs="1" maxOccurs="1" name="noOfItems" type="s:int" /> <s:element minOccurs="0" maxOccurs="1" name="titleField" type="s:string" /> Why does the int parameter have minOccurs set to 1 instead of 0 and how do I change it? I've tried the following without success: [XmlElementAttribute(IsNullable=false)] in the parameter declaration: makes no difference (as expected when you think about it) [XmlElementAttribute(IsNullable=true)] in the parameter declaration: gives error "IsNullable may not be 'true' for value type System.Int32. Please consider using Nullable instead." changing the parameter type to int? : keeps minOccurs="1" and adds nillable="true" [XmlIgnore] in the parameter declaration: the parameter is never output to the WSDL at all

  • Is there a way to get a mobile Safari WebApp to "forget" its state?

    - by Alex Mcp
    I have a nascent bridge scoring app that is meant to be stored locally on an iPod touch/iPhone (iPad? Would probably be fugly...) So far so good, got a custom icon rolling and basic JS navigation laid out, but my problem is that it retains its state when I quit the app. Is there a simple magic Apple meta tag for this? Or is it achieved with javascript? Thanks for any insight.

  • Multiple Input From Keyboard C# WPF

    - by Alex
    I am writing a Tetris clone in WPF. If I hold down the right arrow key, the current piece shifts right. For playability, I want to allow the user to press another key (i.e. F-key) and rotate the moving piece without having to let go of the right arrow key first. Currently when I do this, the piece stops shifting. My first basic attempt at this was hooking into Window_PreviewKeyDown(object sender, KeyEventArgs e) and then sending a message to the controller layer. How do I structure my input-listening code to allow this? My current code Here

  • Localization of attribute values in .NET

    - by Alex Angas
    How can I localize/internationalize attribute values in .NET? My specific example is for ASP.NET web parts such as WebDisplayName, WebDescription, etc. where I inherit from the base class that uses these attributes. Also, is there any difference to doing this with attributes declared in my own classes? Thanks!

  • How do I make PyScript work? Says it cant find python26.dll

    - by Alex
    I installed PyScript to try it out but it just wont start. It only gives me the error: "Error126: Could not open Dll "python26.dll" followed by: "Python could not be properly initialized. We must quit." I think this may have something to do with the PYTHONPATH but since I'm a newbie and dont know what it is or exactly what to put in the PYTHONPATH, after some googling, I ask here. Also, when I tried to install wxPython it was impossible becouse the PYTHONPATH could not be found. I have installed ActivePython 2.6 and the PATH is set so I can access python in cmd.

  • How to learn Ruby on Rails as a complete Programming Beginner?

    - by Alex
    I want to build a scalable dynamic Web Application. I have never programmed an Object Oriented language before. Or, let's just say I am completely new to programming, because the previous experiences aren't worth talking about. I know I have a really big task ahead of me ^^ but I wanted to get into coding for the last 10 years and now that I'm finally doing it, I would like to know how to get there in the most efficient way. Any good books/tutorials you could recommend? Would it really make sense to learn other, better documented languages before learning RoR? Or would it be better for a beginner to learn C# with ASP.NET first? Thank you for your help in advance ;-)

  • mysql replace matching but not changing

    - by alex
    I've used mysql's update replace function before, but even though I think I'm following the same syntax, I can't get this to work-it matches the rows, but doesn't replace. Here's what I'm trying to do: mysql> update contained_widgets set preference_values = replace(preference_values, '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li>', '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li> <li> <a_href="/projects"><span class="not-tc">Projects</span></a></li>'); Query OK, 0 rows affected (0.00 sec) Rows matched: 77 Changed: 0 Warnings: 0 I don't see what I'm missing. Any help is appreciated. I edited "a " to "a_" because the site thinks I'm posting spam links otherwise.

  • Is there an easy way to replace a deprecated method call in Xcode?

    - by Alex Basson
    So iOS 6 deprecates presentModalViewController:animated: and dismissModalViewControllerAnimated:, and it replaces them with presentViewController:animated:completion: and dismissViewControllerAnimated:completion:, respectively. I suppose I could use find-replace to update my app, although it would be awkward with the present* methods, since the controller to be presented is different every time. I know I could handle that situation with a regex, but I don't feel comfortable enough with regex to try using it with my 1000+-files-big app. So I'm wondering: Does Xcode have some magic "update deprecated methods" command or something? I mean, I've described my particular situation above, but in general, deprecations come around with every OS release. Is there a better way to update an app than simply to use find-replace?

  • Using Time datatype in MySQL without seconds

    - by Alex
    I'm trying to store a 12/24hr (ie; 00:00) clock time in a MySQL database. At the moment I am using the time datatype. This works ok but it insists on adding the seconds to the column. So you enter 09:20 and it is stored as 09:20:00. Is there any way I can limit it in MySQL to just 00:00?

  • Java convert JSONObject to URL parameter

    - by Alex Ivasyuv
    What is the elegant way to convert JSONObject to URL parameters. For example, JSONObject: {stat: {123456: {x: 1, y: 2}, 123457: {z: 5, y: 2}}}} this should be like: stat[123456][x]=1&stat[123456][y]=2&stat[123457][z]=5&stat[123457][y]=2 of course with escaped symbols, and of course JSON object could be more complicated.. Maybe there already exist some mechanisms for that? Thanks,
