  • 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}" />

  • Fastest tr:hover method

    - by Alex
    What is the single fastest method for table row hover css change? I've tried jQuery (onmouseover/out) and CSS with tr:hover, but once I make my page fullscreen (1920x1200) the performance on my grid is getting just sluggish enough to give the entire page a feel of being sub-par. That's on a grid with 25 rows, and some spans and divs per row. I've tried IE and Google Chrome. Is there another, faster method? What is generally considered the fastest method across browsers for doing hover CSS changes?

  • 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.

  • 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?

  • 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?

  • 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.

  • 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 ;-)

  • Deployment of SQL Server: installing a second instance?

    - by Workshop Alex
    Simple problem. I'm working on a Delphi 2007/WIN32 application which now uses MS Access as simple data store. I have to modify it to support SQL Server Express, which is easy. These modifications are working so the application can be deployed using either SQL Server or MS Access. (Whatever the user prefers.) I did consider deploying the whole application together with the SQL Compact but this is not practicak. Using SQL Server Express 2008 instead of 2005 is an option, but also has a few nasty side-effects which we don't want to resolve for now. The problem is deploying the whole project. The installation with SQL Server would need a quiet installation so the user won't notice it. SQL Server is mentioned in the documentation so they know it's there. We just don't want to bother them with technical issues. In most cases, such an installation will go just fine. But what if the user already has an SQL Server (2005) installation which is used for something else? Personally, I would prefer to just install a second instance of SQL Server on their system so it won't conflict with the other installation. (Thus, if they uninstall the other app, the SQL instance will just stay installed.) While SQL Server 2005 and 2008 can be installed on the same system simply by using two different names for the instance, I wonder if it's also possible to install SQL Server 2005 twice on a single system to get two instances. And if possible, how?

  • How to setup Eclipse PDT on a bare Windows box?

    - by Alex R
    I have installed Eclipse PDT All-In-One and nothing works (I can edit PHP source but cannot execute any PHP Scripts). Do I also need to install my own PHP interpreter? Do I need XAMPP? WAMP? Cygwin? XDebug? Zend? I'm looking for the smallest amount of stuff that I need to install to get a working PHP IDE, starting with an empty install of Windows Vista.

  • Trying to start a service on boot on Android

    - by Alex
    I've been trying to start a service when a device boots up on android, but I cannot get it to work. I've looked a number of links online but none of the code is working. Am I forgetting something? This is my code. Manifest <receiver android:name=".StartServiceAtBootReceiver" android:enabled="true" android:exported="false" android:label="StartServiceAtBootReceiver"> <intent-filter> <action android:name="android.intent.action._BOOT_COMPLETED"/> </intent-filter> </receiver> <service android:enabled="true" android:name="com.test.RunService"/> Receiver OnReceive public void onReceive(Context context, Intent intent) { if("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) { Intent serviceLauncher = new Intent(context, RunService.class); context.startService(serviceLauncher); Log.v("TEST", "Service loaded at start"); } } Thanks,
