• C#, Generic Lists and Inheritance

  - by Andy

  I have a class called Foo that defines a list of objects of type A: class Foo { List<A> Items = new List<A>(); } I have a class called Bar that can save and load lists of objects of type B: class Bar { void Save(List<B> ComplexItems); List<B> Load(); } B is a child of A. Foo, Bar, A and B are in a library and the user can create children of any of the classes. What I would like to do is something like the following: Foo MyFoo = new Foo(); Bar MyBar = new Bar(); MyFoo.Items = MyBar.Load(); MyBar.Save(MyFoo.Items); Obviously this won't work. Is there a clever way to do this that avoids creating intermediate lists? thanks, Andy

• Delete the first line that matches a pattern

  - by gioele

  How can I use sed to delete only the first line that contains a certain pattern? For example, I want to remove the first line matching FAA from this document: 1. foo bar quuz 2. foo FAA bar (this should go) 3. quuz quuz FAA (this should remain) 4. quuz FAA bar (this should also remain) The result should be 1. foo bar quuz 3. quuz quuz FAA (this should remain) 4. quuz FAA bar (this should also remain) A solution for POSIX sed would be greatly appreciated, GNU sed is OK.

• How to avoid "incomplete implementation" warning in partial base class

  - by garph0

  I have created a protocol that my classes need to implement, and then factored out some common functionality into a base class, so I did this: @protocol MyProtocol - (void) foo; - (void) bar; @end @interface Base <MyProtocol> @end @interface Derived_1 : Base @end @interface Derived_2 : Base @end @implementation Base - (void) foo{ //something foo } @end @implementation Derived_1 - (void) bar{ //something bar 1 } @end @implementation Derived_2 - (void) bar{ //something bar 2 } @end In this way in my code I use a generic id<MyProtocol>. The code works (as long as Base is not used directly) but the compiler chokes at the end of the implementation of Base with a warning: Incomplete implementation of class Base Is there a way to avoid this warning or, even better, a more proper way to obtain this partially implemented abstract base class behavior in Objc?

• In scala can I pass repeated parameters to other methods?

  - by Fred Haslam

  Here is something I can do in java, take the results of a repeated parameter and pass it to another method: public void foo(String ... args){bar(args);} public void bar(String ... args){System.out.println("count="+args.length);} In scala it would look like this: def foo(args:String*) = bar(args) def bar(args:String*) = println("count="+args.length) But this won't compile, the bar signature expects a series of individual strings, and the args passed in is some non-string structure. For now I'm just passing around arrays. It would be very nice to use starred parameters. Is there some way to do it?

• C++ Generic List Assignment

  - by S73417H

  I've clearly been stuck in Java land for too long... Is it possible to do the C++ equivalent of the following Java code: // Method List<Bar> getBars() { return new LinkedList<Bar>(); } // Assignment statement. List<Foo> stuff = getBars(); Where Foo is a sub-class of Bar. So in C++.... std::list<Bar> & getBars() { std::list<Bar> bars; return bars; } std::list<Foo> stuff = getBars(); Hope that makes sense....

• How to serialize this Xml in .NET (array)

  - by Morri

  I need Xml that looks like this <foo> <bar ... /> <bar ... /> </foo> And currently have the following class structure : [XmlRoot("foo")] public class Foo { [XmlArrayItem("bar")] public List<Bar> myBars; } But this gives me Xml where bar items are wrapped inside a bars element. How should I define my custom XmlAttributes so I'd get the Xml structure I need?

• Can you have a web application project produce multiple DLLS?

  - by chris

  I have a VS 2008 web application project that is getting large. My structure looks like: - WebRoot - Common/ - Foo/ - Bar/ - Baz/ so I end up with a single Webroot.dll that contains the code for common, foo, bar, and baz. Is it possible to set it so that I end up with common/ in webroot.dll, and code in foo ends up in foo.dll, bar in bar.dll, etc? Update: A couple of suggestions to move some stuff into class libraries. We already have a dozen or so separate class library projects as part of the solution; Foo, Bar and Baz contain nothing but web forms and the associated code-behinds, so moving them into separate class library projects is not feasible.

• Domain Redirection While Maintaining Original URL

  - by Steve

  I have two domains ("this_site.com" and "that_site.com") that I want to point to the same place (same set of files). BUT What I really want to do is maintain the original URL in the address bar while the visitor accesses the different pages. Example: The primary domain holding the web files is "this_site.com". If I type in "that_site.com" in the address bar, I want the address bar to keep displaying "that_site.com" no matter where they go on the web site. Normal domain redirection causes the URL displayed in the address bar to change to the 'master' domain (i.e. the visitor that typed in "that_site.com" will see the address bar's URL change to "this_site.com"). Is there some sort of .htaccess trick that I can employ to do this? What I'm trying to do is NOT confuse visitors who visit one URL and find themselves on a different URL as well as avoid the additional expense and trouble of having to maintain two separate hosting accounts.

• Access a static variable by $var::$reference

  - by chuckg

  I am trying to access a static variable within a class by using a variable class name. I'm aware that in order to access a function within the class, you use call_user_func(): class foo { function bar() { echo 'hi'; } } $class = "foo"; all_user_func(array($class, 'bar')); // prints hi However, this does not work when trying to access a static variable within the class: class foo { public static $bar = 'hi'; } $class = "foo"; call_user_func(array($class, 'bar')); // nothing echo $foo::$bar; // invalid How do I get at this variable? Is it even possible? I have a bad feeling this is only available in PHP 5.3 going forward and I'm running PHP 5.2.6. Thanks.

• Is read-only auto-imlemented property possible?

  - by abatishchev

  Hello. I found a topic on MSDN that talks that yes, this is possible. I did a test that seems to break this statement: using System; namespace Test { class Program { static void Main(string[] args) { Foo f = new Foo("1"); Console.WriteLine(f.Bar); // prints 1 f.Test("2"); Console.WriteLine(f.Bar);// successfully prints 2 } } class Foo { public Foo(string b) { this.Bar = b; } public string Bar { get; private set; } public void Test(string b) { // this would be impossible for readonly field! // next error would be occur: CS0191 or CS0191 // A readonly field cannot be assigned to (except in a constructor or a variable initializer) this.Bar = b; } } } Where am I wrong?

• C# Why does calling an interface member from a class generate an error?

  - by Jack

  So I have an interface: interface IFoo { int Bar(); int this[int i] {get; set;} } And a class that derives from it class Foo : IFoo { public int IFoo.Bar() { //Implementation { public int IFoo.this[int i] { //Implementation } } Now, I try to do this: var fooey = new Foo(); int i = Fooey.Bar(); or this: int i = Fooey[4]; I would expect these to work properly. However, the compiler generates an error as if such members don't exist. Why is that? I am aware I can cast Foo as IFoo, but I am also aware that casting is costly to performance, which is often the reason to use interfaces in the first place. EDIT 1: These are the errors generated 'Foo' does not contain a definition for 'Bar' and no extension method 'Bar' accepting a first argument of type 'Foo' could be found (are you missing a using directive or an assembly reference?) "Cannot apply indexing to an expression of type 'Foo'"

• IE9 Beta

  - by Daniel Moth

  I've been using Internet Explorer 8 since the early pre-release bits, but I never tried IE9 until today – the day the Beta is available. I downloaded it from here: http://www.beautyoftheweb.com/ The download took longer than what I expected, but I was doing other stuff, so no bother. After coming down, it asked me to reboot my computer. Really hate when apps do that, but I did it anyway. The first time I launched it, it prompted me with a list of add-ons I should disable including the start-up time that I could save fore each one. It even let me configure the prompt so, for example, it won't prompt me again unless an add-on contributes to more than 1 second of the startup time. Cool. First thing I noticed is that the search bar had gone and, as you'd expect, you have to search from the address box. I totally despise this feature. The first thing I've been doing with all versions of IE is to turn off the automatic searching from the address bar and now I have no way of searching if I do that. Ridiculous. The second thing I notice is that the tabs are next to the address bar and cannot be moved to go below it. One word for that decision: appalling (and, no, I didn't accidentally drop an 'e' and added an 'l' in the previous word). The third thing I notice to the right is the favorites button (star icon) and when I click on it, it brings up the favorites explorer under it on the right; then I pin the explorer and it jumps to the left(!). Why move the entry point to this feature to the right instead of leaving it on the left is beyond me (other than wanting to retrain me on what I've been used to for all this time), but the fact that pinning it makes it jump sides is… an "astonishing" design decision. As I browse I notice a little annoying pop up in the bottom left every time I hover over a link; there is no status bar. I correctly guessed to right click at the top and turn on the status bar (which also got rid of the popup thereafter) and while I am at it, I bring back my favorites bar which was hidden by default (and am pleased to see that all my favorites are still there). The next thing I notice, I like: IE9 is fast. No joke, I visit sites and they seem to be loading visibly much faster – try it! Beyond the speed, I am interested to find out what else is new. I searched and found a few good links: What's new in Internet Explorer 9 Internet Explorer 9 Features (check out the links under "Clean") Top Features If you are a developer, check out IE's msdn home for many articles, e.g. this section on Canvas and SVG. Either way: wherever you are, get IE9 Beta now and judge for yourself. If you don't like it, you can always uninstall (which auto-restores the previous version). Comments about this post welcome at the original blog.

• Passing ActionListeners in Java, pack()

  - by Crystal

  Two questions. First question is I'm trying to create a simple form that when you press a button, it adds a Person object to the ArrayList. However, since I am not used to GUIs, I tried creating one and am first just trying to get the user input from the JTextField, create an ActionListener object of the appropriate type, so once that works, then I can pass in all the JTextField inputs to create my Person object. Unfortunately, I am not getting any data when I type in something to the firstName JTextField and was wondering if someone could look at my code below. import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.util.List; import java.util.ArrayList; public class AddressBook { public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { AddressBookFrame frame = new AddressBookFrame();

I don't like the stretch look and was hoping the JTextFields could be just one line long, not a big box. Same thing with the buttons. Any thoughts? Thanks.

• Setup a new domain controller over a temporary VPN, but now Windows delays startup?

  - by Kris Anderson

  I'm migrating servers from colo locations to Amazon's VPC EC2 instances. If anyone hasn't worked with Amazon VPC before, VPN is a pain in the arse! Anyways, I setup a new server that acts as the domain controller for our Amazon VPC. In order to migrate all the user accounts from our existing domain controllers I manually connected to our colo VPN using my user account on the new Amazon EC2 machine. I was able to join the domain and the new Amazon server became another domain controller on our network. So far so good. The problem I'm having is that when booting the EC2 domain controller (which is no longer connected to the VPN so it can't communicate with the existing controllers), it takes a good 6-8 minuted before I can remote into the server (instead of the 1-2 minutes it should take). Also, during this time most of the services we also run (like IIS) also give 404 errors until the 6-8 minutes have passed. It's almost like the domain controller is attempting to reach the other domain controllers first and after 6-8 minutes it falls back to the one located on the local machine? I don't think that's what's happening though, because Server 2008 R2 doesn't have primary and backup domain controllers. They're all equal as far as Windows is concerned. For my network adapter I have only one DNS listed, 127.0.0.1, so it should be looking up the local domain controller and not the other domain controllers it connected to over VPN when VPN was enabled. In the server logs I'm seeing these warnings pop up during a reboot: The winlogon notification subscriber is taking long time to handle the notification event (CreateSession). The winlogon notification subscriber took 409 second(s) to handle the notification event (CreateSession). Any ideas on what's happening here? I would try removing the existing domain controllers from the new Amazon EC2 machine, but I still need to connect over VPN a few times to migrate some data between the servers, and I don't want that change being reflected back to the other domain controllers in our colo locations.

• How do I connect a 2008 server to a 2003 server active directory?

  - by Matt

  Our DC is running Windows Server 2003. I've just set up Windows Server 2008 and have terminal server running on it. When setting the terminal server permissions, it was able to allow a group name that was read from the domain. In the DC the new terminal server shows up as a computer in the domain. I can also log in as a user within the domain even though that user doesn't exist locally on the new server. However, when I go to set sharing permissions on the new machine it doesn't show my domain as a location. Instead it is only looking at location "machinename" and not allowing domain to be seen or added. Is there something I'm missing? Ok, lots of errors in the event log. We have this: The winlogon notification subscriber is taking long time to handle the notification event (Logon). Followed by this: The winlogon notification subscriber took 121 second(s) to handle the notification event (Logon). Followed by: The processing of Group Policy failed because of lack of network connectivity to a domain controller. This may be a transient condition. A success message would be generated once the machine gets connected to the domain controller and Group Policy has succesfully processed. If you do not see a success message for several hours, then contact your administrator. I think this might be the same problem I'm having http://serverfault.com/questions/24420/primary-domain-controller-slow Solved. The issue was that I had changed from DHCP to static and put the wrong DNS server IP in. i.e. firewall instead of DC/DNS server.

• VNC Address Book - Window Invisible? Working as intended?

  - by user1445967

  I have VNC Server and VNC Viewer on the same PC with Windows 7 Ultimate x64. Is VNC Address Book supposed to have a main application window? I can't tell if this is bugged or working as intended. When I start VNC Address book, it creates an item in the task list and also an icon in the notification area. If I click the task list item once, nothing happens. If I click again, it disappears from the task list but remains in the notification area**. If I right-click the icon on the notification area, there is an option 'open address book', which if chosen, creates the item in the task list again, with the exact same behavior. If I left or right click on the address book icon, I have ways to connect to servers in the address book. However I have no way to add/remove/edit servers in the address book. **Note that this behavior is identical to that of an application with a main window where there is an option to 'minimize to system tray / notification area'. Only here, no main window is visible, ever. If fixing this problem is beyond the scope of this site, that's fine, but at this point I have no real way to tell if the program is malfunctioning on my pc or if it is far more minimalist than I expected. There appears to be no forum on realvnc.com where I can ask about this, perhaps this is to prevent me from getting any help unless I pay to register?

• log activity. intrusion detection. user event notification ( interraction ). messaging

  - by Julian Davchev

  Have three questions that I somehow find related so I put them in same place. Currently building relatively large LAMP system - making use of messaging(activeMQ) , memcache and other goodies. I wonder if there are best practices or nice tips and tricks on howto implement those. System is user aware - meaning all actions done can be bind to particular logged user. 1. How to log all actions/activities of users? So that stats/graphics might be extracted later for analysing. At best that will include all url calls, post data etc etc. Meaning tons of inserts. I am thinking sending messages to activeMQ and later cron dumping in DB and cron analysing might be good idea here. Since using Zend Framework I guess I may use some request plugin so I don't have to make the log() call all over the code. 2.How to log stuff so may be used for intrusion detection? I know most things might be done on http level using apache mods for example but there are also specific cases like (5 failed login attempts in a row (leads to captcha) etc etc..) This also would include tons of inserts. Here I guess direct usage of memcache might be best approach as data don't seem vital to be permanantly persisted. Not sure if cannot use data from point 1. 3.System will notify users of some events. Like need approval , something broke..whatever.Some events will need feedback(action) from user, others are just informational. Wonder if there is common solutions for needs like this. Example: Based on occuring event(s) user will be notifed (user inbox for example) what happend. There will be link or something to lead him to details of thingy that happend and take action accordingly. Those seem trivial at first look but problem I see if coding it directly is becoming really fast hard to maintain.

• Announcing the release of the Windows Azure SDK 2.1 for .NET

  - by ScottGu

  Today we released the v2.1 update of the Windows Azure SDK for .NET.  This is a major refresh of the Windows Azure SDK and it includes some great new features and enhancements. These new capabilities include: Visual Studio 2013 Preview Support: The Windows Azure SDK now supports using the new VS 2013 Preview Visual Studio 2013 VM Image: Windows Azure now has a built-in VM image that you can use to host and develop with VS 2013 in the cloud Visual Studio Server Explorer Enhancements: Redesigned with improved filtering and auto-loading of subscription resources Virtual Machines: Start and Stop VM’s w/suspend billing directly from within Visual Studio Cloud Services: New Emulator Express option with reduced footprint and Run as Normal User support Service Bus: New high availability options, Notification Hub support, Improved VS tooling PowerShell Automation: Lots of new PowerShell commands for automating Web Sites, Cloud Services, VMs and more All of these SDK enhancements are now available to start using immediately and you can download the SDK from the Windows Azure .NET Developer Center.  Visual Studio’s Team Foundation Service (http://tfs.visualstudio.com/) has also been updated to support today’s SDK 2.1 release, and the SDK 2.1 features can now be used with it (including with automated builds + tests). Below are more details on the new features and capabilities released today: Visual Studio 2013 Preview Support Today’s Window Azure SDK 2.1 release adds support for the recent Visual Studio 2013 Preview. The 2.1 SDK also works with Visual Studio 2010 and Visual Studio 2012, and works side by side with the previous Windows Azure SDK 1.8 and 2.0 releases. To install the Windows Azure SDK 2.1 on your local computer, choose the “install the sdk” link from the Windows Azure .NET Developer Center. Then, chose which version of Visual Studio you want to use it with.  Clicking the third link will install the SDK with the latest VS 2013 Preview: If you don’t already have the Visual Studio 2013 Preview installed on your machine, this will also install Visual Studio Express 2013 Preview for Web. Visual Studio 2013 VM Image Hosted in the Cloud One of the requests we’ve heard from several customers has been to have the ability to host Visual Studio within the cloud (avoiding the need to install anything locally on your computer). With today’s SDK update we’ve added a new VM image to the Windows Azure VM Gallery that has Visual Studio Ultimate 2013 Preview, SharePoint 2013, SQL Server 2012 Express and the Windows Azure 2.1 SDK already installed on it.  This provides a really easy way to create a development environment in the cloud with the latest tools. With the recent shutdown and suspend billing feature we shipped on Windows Azure last month, you can spin up the image only when you want to do active development, and then shut down the virtual machine and not have to worry about usage charges while the virtual machine is not in use. You can create your own VS image in the cloud by using the New->Compute->Virtual Machine->From Gallery menu within the Windows Azure Management Portal, and then by selecting the “Visual Studio Ultimate 2013 Preview” template: Visual Studio Server Explorer: Improved Filtering/Management of Subscription Resources With the Windows Azure SDK 2.1 release you’ll notice significant improvements in the Visual Studio Server Explorer. The explorer has been redesigned so that all Windows Azure services are now contained under a single Windows Azure node.  From the top level node you can now manage your Windows Azure credentials, import a subscription file or filter Server Explorer to only show services from particular subscriptions or regions. Note: The Web Sites and Mobile Services nodes will appear outside the Windows Azure Node until the final release of VS 2013. If you have installed the ASP.NET and Web Tools Preview Refresh, though, the Web Sites node will appear inside the Windows Azure node even with the VS 2013 Preview. Once your subscription information is added, Windows Azure services from all your subscriptions are automatically enumerated in the Server Explorer. You no longer need to manually add services to Server Explorer individually. This provides a convenient way of viewing all of your cloud services, storage accounts, service bus namespaces, virtual machines, and web sites from one location: Subscription and Region Filtering Support Using the Windows Azure node in Server Explorer, you can also now filter your Windows Azure services in the Server Explorer by the subscription or region they are in.  If you have multiple subscriptions but need to focus your attention to just a few subscription for some period of time, this a handy way to hide the services from other subscriptions view until they become relevant. You can do the same sort of filtering by region. To enable this, just select “Filter Services” from the context menu on the Windows Azure node: Then choose the subscriptions and/or regions you want to filter by. In the below example, I’ve decided to show services from my pay-as-you-go subscription within the East US region: Visual Studio will then automatically filter the items that show up in the Server Explorer appropriately: With storage accounts and service bus namespaces, you sometimes need to work with services outside your subscription. To accommodate that scenario, those services allow you to attach an external account (from the context menu). You’ll notice that external accounts have a slightly different icon in server explorer to indicate they are from outside your subscription. Other Improvements We’ve also improved the Server Explorer by adding additional properties and actions to the service exposed. You now have access to most of the properties on a cloud service, deployment slot, role or role instance as well as the properties on storage accounts, virtual machines and web sites. Just select the object of interest in Server Explorer and view the properties in the property pane. We also now have full support for creating/deleting/update storage tables, blobs and queues from directly within Server Explorer.  Simply right-click on the appropriate storage account node and you can create them directly within Visual Studio: Virtual Machines: Start/Stop within Visual Studio Virtual Machines now have context menu actions that allow you start, shutdown, restart and delete a Virtual Machine directly within the Visual Studio Server Explorer. The shutdown action enables you to shut down the virtual machine and suspend billing when the VM is not is use, and easily restart it when you need it: This is especially useful in Dev/Test scenarios where you can start a VM – such as a SQL Server – during your development session and then shut it down / suspend billing when you are not developing (and no longer be billed for it). You can also now directly remote desktop into VMs using the “Connect using Remote Desktop” context menu command in VS Server Explorer.  Cloud Services: Emulator Express with Run as Normal User Support You can now launch Visual Studio and run your cloud services locally as a Normal User (without having to elevate to an administrator account) using a new Emulator Express option included as a preview feature with this SDK release.  Emulator Express is a version of the Windows Azure Compute Emulator that runs a restricted mode – one instance per role – and it doesn’t require administrative permissions and uses 40% less resources than the full Windows Azure Emulator. Emulator Express supports both web and worker roles. To run your application locally using the Emulator Express option, simply change the following settings in the Windows Azure project. On the shortcut menu for the Windows Azure project, choose Properties, and then choose the Web tab. Check the setting for IIS (Internet Information Services). Make sure that the option is set to IIS Express, not the full version of IIS. Emulator Express is not compatible with full IIS. On the Web tab, choose the option for Emulator Express. Service Bus: Notification Hubs With the Windows Azure SDK 2.1 release we are adding support for Windows Azure Notification Hubs as part of our official Windows Azure SDK, inside of Microsoft.ServiceBus.dll (previously the Notification Hub functionality was in a preview assembly). You are now able to create, update and delete Notification Hubs programmatically, manage your device registrations, and send push notifications to all your mobile clients across all platforms (Windows Store, Windows Phone 8, iOS, and Android). Learn more about Notification Hubs on MSDN here, or watch the Notification Hubs //BUILD/ presentation here. Service Bus: Paired Namespaces One of the new features included with today’s Windows Azure SDK 2.1 release is support for Service Bus “Paired Namespaces”.  Paired Namespaces enable you to better handle situations where a Service Bus service namespace becomes unavailable (for example: due to connectivity issues or an outage) and you are unable to send or receive messages to the namespace hosting the queue, topic, or subscription. Previously,to handle this scenario you had to manually setup separate namespaces that can act as a backup, then implement manual failover and retry logic which was sometimes tricky to get right. Service Bus now supports Paired Namespaces, which enables you to connect two namespaces together. When you activate the secondary namespace, messages are stored in the secondary queue for delivery to the primary queue at a later time. If the primary container (namespace) becomes unavailable for some reason, automatic failover enables the messages in the secondary queue. For detailed information about paired namespaces and high availability, see the new topic Asynchronous Messaging Patterns and High Availability. Service Bus: Tooling Improvements In this release, the Windows Azure Tools for Visual Studio contain several enhancements and changes to the management of Service Bus messaging entities using Visual Studio’s Server Explorer. The most noticeable change is that the Service Bus node is now integrated into the Windows Azure node, and supports integrated subscription management. Additionally, there has been a change to the code generated by the Windows Azure Worker Role with Service Bus Queue project template. This code now uses an event-driven “message pump” programming model using the QueueClient.OnMessage method. PowerShell: Tons of New Automation Commands Since my last blog post on the previous Windows Azure SDK 2.0 release, we’ve updated Windows Azure PowerShell (which is a separate download) five times. You can find the full change log here. We’ve added new cmdlets in the following areas: China instance and Windows Azure Pack support Environment Configuration VMs Cloud Services Web Sites Storage SQL Azure Service Bus China Instance and Windows Azure Pack We now support the following cmdlets for the China instance and Windows Azure Pack, respectively: China Instance: Web Sites, Service Bus, Storage, Cloud Service, VMs, Network Windows Azure Pack: Web Sites, Service Bus We will have full cmdlet support for these two Windows Azure environments in PowerShell in the near future. Virtual Machines: Stop/Start Virtual Machines Similar to the Start/Stop VM capability in VS Server Explorer, you can now stop your VM and suspend billing: If you want to keep the original behavior of keeping your stopped VM provisioned, you can pass in the -StayProvisioned switch parameter. Virtual Machines: VM endpoint ACLs We’ve added and updated a bunch of cmdlets for you to configure fine-grained network ACL on your VM endpoints. You can use the following cmdlets to create ACL config and apply them to a VM endpoint: New-AzureAclConfig Get-AzureAclConfig Set-AzureAclConfig Remove-AzureAclConfig Add-AzureEndpoint -ACL Set-AzureEndpoint –ACL The following example shows how to add an ACL rule to an existing endpoint of a VM. Other improvements for Virtual Machine management includes Added -NoWinRMEndpoint parameter to New-AzureQuickVM and Add-AzureProvisioningConfig to disable Windows Remote Management Added -DirectServerReturn parameter to Add-AzureEndpoint and Set-AzureEndpoint to enable/disable direct server return Added Set-AzureLoadBalancedEndpoint cmdlet to modify load balanced endpoints Cloud Services: Remote Desktop and Diagnostics Remote Desktop and Diagnostics are popular debugging options for Cloud Services. We’ve introduced cmdlets to help you configure these two Cloud Service extensions from Windows Azure PowerShell. Windows Azure Cloud Services Remote Desktop extension: New-AzureServiceRemoteDesktopExtensionConfig Get-AzureServiceRemoteDesktopExtension Set-AzureServiceRemoteDesktopExtension Remove-AzureServiceRemoteDesktopExtension Windows Azure Cloud Services Diagnostics extension New-AzureServiceDiagnosticsExtensionConfig Get-AzureServiceDiagnosticsExtension Set-AzureServiceDiagnosticsExtension Remove-AzureServiceDiagnosticsExtension The following example shows how to enable Remote Desktop for a Cloud Service. Web Sites: Diagnostics With our last SDK update, we introduced the Get-AzureWebsiteLog –Tail cmdlet to get the log streaming of your Web Sites. Recently, we’ve also added cmdlets to configure Web Site application diagnostics: Enable-AzureWebsiteApplicationDiagnostic Disable-AzureWebsiteApplicationDiagnostic The following 2 examples show how to enable application diagnostics to the file system and a Windows Azure Storage Table: SQL Database Previously, you had to know the SQL Database server admin username and password if you want to manage the database in that SQL Database server. Recently, we’ve made the experience much easier by not requiring the admin credential if the database server is in your subscription. So you can simply specify the -ServerName parameter to tell Windows Azure PowerShell which server you want to use for the following cmdlets. Get-AzureSqlDatabase New-AzureSqlDatabase Remove-AzureSqlDatabase Set-AzureSqlDatabase We’ve also added a -AllowAllAzureServices parameter to New-AzureSqlDatabaseServerFirewallRule so that you can easily add a firewall rule to whitelist all Windows Azure IP addresses. Besides the above experience improvements, we’ve also added cmdlets get the database server quota and set the database service objective. Check out the following cmdlets for details. Get-AzureSqlDatabaseServerQuota Get-AzureSqlDatabaseServiceObjective Set-AzureSqlDatabase –ServiceObjective Storage and Service Bus Other new cmdlets include Storage: CRUD cmdlets for Azure Tables and Queues Service Bus: Cmdlets for managing authorization rules on your Service Bus Namespace, Queue, Topic, Relay and NotificationHub Summary Today’s release includes a bunch of great features that enable you to build even better cloud solutions.  All the above features/enhancements are shipped and available to use immediately as part of the 2.1 release of the Windows Azure SDK for .NET. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• Store comparison in variable (or execute comparison when it's given as an string)

  - by BorrajaX

  Hello everyone. I'd like to know if the super-powerful python allows to store a comparison in a variable or, if not, if it's possible calling/executing a comparison when given as an string ("==" or "!=") I want to allow the users of my program the chance of giving a comparison in an string. For instance, let's say I have a list of... "products" and the user wants to select the products whose manufacturer is "foo". He could would input something like: Product.manufacturer == "foo" and if the user wants the products whose manufacturer is not "bar" he would input Product.manufacturer != "bar" If the user inputs that line as an string, I create a tree with an structure like: != / \ manufacturer bar I'd like to allow that comparison to run properly, but I don't know how to make it happen if != is an string. The "manufacturer" field is a property, so I can properly get it from the Product class and store it (as a property) in the leaf, and well... "bar" is just an string. I'd like to know if I can something similar to what I do with "manufacturer": storing it with a 'callable" (kind of) thing: the property with the comparator: != I have tried with "eval" and it may work, but the comparisons are going to be actually used to query a MySQL database (using sqlalchemy) and I'm a bit concerned about the security of that... Any idea will be deeply appreciated. Thank you! PS: The idea of all this is being able to generate a sqlalchemy query, so if the user inputs the string: Product.manufacturer != "foo" || Product.manufacturer != "bar" ... my tree thing can generate the following: sqlalchemy.or_(Product.manufacturer !="foo", Product.manufacturer !="bar") Since sqlalchemy.or_ is callable, I can also store it in one of the leaves... I only see a problem with the "!="

• Can I select 0 columns in SQL Server?

  - by Woody Zenfell III

  I am hoping this question fares a little better than the similar Create a table without columns. Yes, I am asking about something that will strike most as pointlessly academic. It is easy to produce a SELECT result with 0 rows (but with columns), e.g. SELECT a = 1 WHERE 1 = 0. Is it possible to produce a SELECT result with 0 columns (but with rows)? e.g. something like SELECT NO COLUMNS FROM Foo. (This is not valid T-SQL.) I came across this because I wanted to insert several rows without specifying any column data for any of them. e.g. (SQL Server 2005) CREATE TABLE Bar (id INT NOT NULL IDENTITY PRIMARY KEY) INSERT INTO Bar SELECT NO COLUMNS FROM Foo -- Invalid column name 'NO'. -- An explicit value for the identity column in table 'Bar' can only be specified when a column list is used and IDENTITY_INSERT is ON. One can insert a single row without specifying any column data, e.g. INSERT INTO Foo DEFAULT VALUES. One can query for a count of rows (without retrieving actual column data from the table), e.g. SELECT COUNT(*) FROM Foo. (But that result set, of course, has a column.) I tried things like INSERT INTO Bar () SELECT * FROM Foo -- Parameters supplied for object 'Bar' which is not a function. -- If the parameters are intended as a table hint, a WITH keyword is required. and INSERT INTO Bar DEFAULT VALUES SELECT * FROM Foo -- which is a standalone INSERT statement followed by a standalone SELECT statement. I can do what I need to do a different way, but the apparent lack of consistency in support for degenerate cases surprises me. I read through the relevant sections of BOL and didn't see anything. I was surprised to come up with nothing via Google either.

• Why can't I use WCF DataContract and ISerializable on the same class?

  - by Dave

  Hi all, I have a class that I need to be able to serialize to a SQLServer session variable and be available over a WCF Service. I have declared it as follows namespace MyNM { [Serializable] [DataContract(Name = "Foo", Namespace = "http://www.mydomain.co.uk")] public class Foo : IEntity, ISafeCopy<Foo> { [DataMember(Order = 0)] public virtual Guid Id { get; set; } [DataMember(Order = 1)] public virtual string a { get; set; } DataMember(Order = 2)] public virtual Bar c { get; set; } /* ISafeCopy implementation */ } [Serializable] [DataContract(Name = "Bar ", Namespace = "http://www.mydomain.co.uk")] public class Bar : IEntity, ISafeCopy<Bar> { #region Implementation of IEntity DataMember(Order = 0)] public virtual Guid Id { get; set; } [DataMember(Order = 1)] public virtual Baz y { get; set; } #endregion /* ISafeCopy implementation*/ } [Serializable] [DataContract] public enum Baz { [EnumMember(Value = "one")] one, [EnumMember(Value = "two")] two, [EnumMember(Value = "three")] three } But when I try and call this service, I get the following error in the trace log. "System.Runtime.Serialization.InvalidDataContractException: Type 'BarProxybcb100e8617f40ceaa832fe4bb94533c' cannot be ISerializable and have DataContractAttribute attribute." If I take out the Serializable attribute, the WCF service works, but when the object can't be serialized to session. If I remove the DataContract attribute from class Bar, the WCF service fails saying Type 'BarProxy3bb05a31167f4ba492909ec941a54533' with data contract name 'BarProxy3bb05a31167f4ba492909ec941a54533:http://schemas.datacontract.org/2004/07/' is not expected. Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer I've tried adding a KnownType attribute to the foo class [KnownType(typeof(Bar))] But I still get the same error. Can anyone help me out with this? Many thanks Dave

• Django model operating on a queryset

  - by jmoz

  I'm new to Django and somewhat to Python as well. I'm trying to find the idiomatic way to loop over a queryset and set a variable on each model. Basically my model depends on a value from an api, and a model method must multiply one of it's attribs by this api value to get an up-to-date correct value. At the moment I am doing it in the view and it works, but I'm not sure it's the correct way to achieve what I want. I have to replicate this looping elsewhere. Is there a way I can encapsulate the looping logic into a queryset method so it can be used in multiple places? I have this atm (I am using django-rest-framework): class FooViewSet(viewsets.ModelViewSet): model = Foo serializer_class = FooSerializer bar = # some call to an api def get_queryset(self): # Dynamically set the bar variable on each instance! foos = Foo.objects.filter(baz__pk=1).order_by('date') for item in foos: item.needs_bar = self.bar return items I would think something like so would be better: def get_queryset(self): bar = # some call to an api # Dynamically set the bar variable on each instance! return Foo.objects.filter(baz__pk=1).order_by('date').set_bar(bar) I'm thinking the api hit should be in the controller and then injected to instances of the model, but I'm not sure how you do this. I've been looking around querysets and managers but still can't figure it out nor decided if it's the best method to achieve what I want. Can anyone suggest the correct way to model this with django? Thanks.

• How to get forkpty to handle redirection and other bash-isms?

  - by Jeremy Friesner

  Hi all, I've got a GUI C++ program that takes a shell command from the user, calls forkpty() and execvp() to execute that command in a child process, while the parent (GUI) process reads the child process's stdout/stderr output and displays it in the GUI. This all works nicely (under Linux and MacOS/X). For example, if the user enters "ls -l /foo", the GUI will display the contents of the /foo folder. However, bash niceties like output redirection aren't handled. For example, if the user enters "echo bar /foo/bar.txt", the child process will output the text "bar /foo/bar.txt", instead of writing the text "bar" to the file "/foo/bar.txt". Presumably this is because execvp() is running the executable command "echo" directly, instead of running /bin/bash and handing it the user's command to massage/preprocess. My question is, what is the correct child process invocation to use, in order to make the system behave exactly as if the user had typed in his string at the bash prompt? I tried wrapping the user's command with a /bin/bash invocation, like this: /bin/bash -c the_string_the_user_entered, but that didn't seem to work. Any hints?
