  • How to set default xrandr settings?

    - by echo-flow
    I'm trying to enable dual monitors in Ubuntu. This is working fine, but every time I do it, desktop effects is disabled. I think I've found the reason why, though: https://wiki.ubuntu.com/X/Config/Multihead/ As with the GNOME XRandR configuration method, setting Virtual to too large a value may result in a loss of hardware acceleration, and thus an inability to use Compiz and its desktop effects. When I use the GNOME monitor applet, or the Monitors configuration in the System menu, the default xrandr settings puts the second monitor to the right of the first, and, as I found with this bug, for most monitors this creates a virtual desktop larger than the maximum 2048 horizontal resolution needed for hardware acceleration on my netbook hardware. So, it seems like if I can modify xrandr's default settings so that it places the new desktop above or below (north or south of) the main LVDS display, then hardware acceleration, and therefore compiz will continue to work. Can anyone tell me, what is the easiest way to achieve this? UPDATE: I have confirmed that multihead support with desktop effects and hardware acceleration works when I move the external monitor display north of the main LVDS display. Right now this involves the following process: plugging in the external monitor, starting the Monitors configuration menu, desktop effects are disabled automatically (and all of the windows on my workspaces are moved to the first workspace), repositioning the external display so that it is north of LVDS display and clicking apply, and then navigating to the Appearance menu and telling it to reenable desktop effects. Is there a simpler way do this? UPDATE 2: OK, so I thought that perhaps the GNOME Monitors configuration screen was trying to be clever, and might be disbling desktop effects. So, I just tried using the xrandr command-line client instead, as follows: xrandr --output VGA1 --above LVDS1 When I do that, desktop effects are still disabled, and I need to manually reenable them. This, despite the fact that hardware acceleration works, and there is never a point where hardware acceleration stops working because the horizontal dimension of the virtual display is too large. So what program is trying to be clever, and is turning off desktop effects when it doesn't need to? And how do I make it stop? If there were a way to re-enable desktop effects from the command line, which I could then put into a script along with the proper xrandr invocation, I would accept that as a workaround. UPDATE 3: OK, here's my script to enable a second monitor with desktop effects. It might be evil, I'm not sure: second-monitor.sh xrandr --output VGA1 --above LVDS1 sleep 3 compiz --replace & The sleep statement might not be necessary. If there's a better way to do this, please let me know. UPDATE 4: This is a Dell Mini Inspiron 1012.

  • Windows Azure SDK 1.3 addresses early adopter feedback

    - by Eric Nelson
    At the end of November 2010 we released a new version of the Windows Azure SDK which contains many new features driven by the great feedback of early adopters plus a shiny new portal. New Portal implemented in Silverlight: The new portal is implemented using Silverlight and replaces the (IMHO rather clunky) original HTML + JavaScript portal. It is 100% better although does still have a few bugs. Enjoy! P.S. You can if you wish still use the old portal:   New runtime functionality: The following functionality is now generally available through the Windows Azure SDK and Windows Azure Tools for Visual Studio and the new Windows Azure Management Portal: Elevated Privileges and Full IIS. You can now run a portion or all of your code in Web and Worker roles with elevated administrator privileges. The Web role now provides Full IIS functionality, which enables multiple IIS sites per Web role and the ability to install IIS modules. Remote Desktop functionality enables you to connect to a running instance of your application or service in order to monitor activity and troubleshoot common problems. Windows Server 2008 R2 Roles: Windows Azure now supports Windows Server 2008 R2 in its Web, worker and VM roles. This new support enables you to take advantage of the full range of Windows Server 2008 R2 features such as IIS 7.5, AppLocker, and enhanced command-line and automated management using PowerShell Version 2.0. New runtime functionality – in beta: Windows Azure Virtual Machine Role: Support for more types of new and existing Windows applications will soon be available with the introduction of the Virtual Machine (VM) role. You can move more existing applications to Windows Azure, reducing the need to make costly code or deployment changes. Extra Small Windows Azure Instance, which is priced at $0.05 per compute hour, provides developers with a cost-effective training and development environment. Developers can also use the Extra Small instance to prototype cloud solutions at a lower cost. Windows Azure Connect: (formerly Project Sydney), which enables a simple and easy-to-manage mechanism to set up IP-based network connectivity between on-premises and Windows Azure resources, is the first Windows Azure Virtual Network feature that we’re making available as a CTP. You can sign up for any of the betas via the Windows Azure Management Portal. Improved processes and simplified operations New portal! (see above) Access to new diagnostic information including the ability to click on a role to see role type, deployment time and last reboot time A new sign-up process that dramatically reduces the number of steps needed to sign up for Windows Azure. New scenario based Windows Azure Platform forums to help answer questions and share knowledge more efficiently. Multiple Service Administrators: Windows Azure now supports multiple Windows Live IDs to have administrator privileges on the same Windows Azure account. The objective is to make it easy for a team to work on the same Windows Azure account while using their individual Windows Live IDs.   Related Links Please also let us know through Microsoft Platform Ready if and when you intend to build an application using the Windows Azure Platform. Or indeed if you already have (Well done). You will get access to some great benefits if you do (more on that in a future post). It also really helps us better understand the demand out there which directly impacts how we will plan the next six months of activities around the Windows Azure Platform.

  • Best Practices - Core allocation

    - by jsavit
    This post is one of a series of "best practices" notes for Oracle VM Server for SPARC (also called Logical Domains) Introduction SPARC T-series servers currently have up to 4 CPU sockets, each of which has up to 8 or (on SPARC T3) 16 CPU cores, while each CPU core has 8 threads, for a maximum of 512 dispatchable CPUs. The defining feature of Oracle VM Server for SPARC is that each domain is assigned CPU threads or cores for its exclusive use. This avoids the overhead of software-based time-slicing and emulation (or binary rewriting) of system state-changing privileged instructions used in traditional hypervisors. To create a domain, administrators specify either the number of CPU threads or cores that the domain will own, as well as its memory and I/O resources. When CPU resources are assigned at the individual thread level, the logical domains constraint manager attempts to assign threads from the same cores to a domain, and avoid "split core" situations where the same CPU core is used by multiple domains. Sometimes this is unavoidable, especially when domains are allocated and deallocated CPUs in small increments. Why split cores can matter Split core allocations can silenty reduce performance because multiple domains with different address spaces and memory contents are sharing the core's Level 1 cache (L1$). This is called false cache sharing since even identical memory addresses from different domains must point to different locations in RAM. The effect of this is increased contention for the cache, and higher memory latency for each domain using that core. The degree of performance impact can be widely variable. For applications with very small memory working sets, and with I/O bound or low-CPU utilization workloads, it may not matter at all: all machines wait for work at the same speed. If the domains have substantial workloads, or are critical to performance then this can have an important impact: This blog entry was inspired by a customer issue in which one CPU core was split among 3 domains, one of which was the control and service domain. The reported problem was increased I/O latency in guest domains, but the root cause might be higher latency servicing the I/O requests due to the control domain being slowed down. What to do about it Split core situations are easily avoided. In most cases the logical domain constraint manager will avoid it without any administrative action, but it can be entirely prevented by doing one of the several actions: Assign virtual CPUs in multiples of 8 - the number of threads per core. For example: ldm set-vcpu 8 mydomain or ldm add-vcpu 24 mydomain. Each domain will then be allocated on a core boundary. Use the whole core constraint when assigning CPU resources. This allocates CPUs in increments of entire cores instead of virtual CPU threads. The equivalent of the above commands would be ldm set-core 1 mydomain or ldm add-core 3 mydomain. Older syntax does the same thing by adding the -c flag to the add-vcpu, rm-vcpu and set-vcpu commands, but the new syntax is recommended. When whole core allocation is used an attempt to add cores to a domain fails if there aren't enough completely empty cores to satisfy the request. See https://blogs.oracle.com/sharakan/entry/oracle_vm_server_for_sparc4 for an excellent article on this topic by Eric Sharakan. Don't obsess: - if the workloads have minimal CPU requirements and don't need anywhere near a full CPU core, then don't worry about it. If you have low utilization workloads being consolidated from older machines onto a current T-series, then there's no need to worry about this or to assign an entire core to domains that will never use that much capacity. In any case, make sure the most important domains have their own CPU cores, in particular the control domain and any I/O or service domain, and of course any important guests. Summary Split core CPU allocation to domains can potentially have an impact on performance, but the logical domains manager tends to prevent this situation, and it can be completely and simply avoided by allocating virtual CPUs on core boundaries.

  • Help Me Help You Fix That

    - by BuckWoody
    If you've been redirected here because you posted on a forum, or asked a question in an e-mail, the person wanted you to know how to get help quickly from a group of folks who are willing to do so - but whose time is valuable. You need to put a little effort into the question first to get others to assist. This is how to do that. It will only take you a moment to read... 1. State the problem succinctly in the title When an e-mail thread starts, or a forum post is the "head" of the conversation, you'll attract more helpers by using a descriptive headline than a vague one. This: "Driver for Epson Line Printer Not Installing on Operating System XYZ" Not this: "Can't print - PLEASE HELP" 2. Explain the Error Completely Make sure you include all pertinent information in the request. More information is better, there's almost no way to add too much data to the discussion. What you were doing, what happened, what you saw, the error message, visuals, screen shots, whatever you can include. This: "I'm getting error '5203 - Driver not compatible with Operating System since about 25 years ago' in a message box on the screen when I tried to run the SETUP.COM file from my older computer. It was a 1995 Compaq Proliant and worked correctly there.." Not this: "I get an error message in a box. It won't install." 3. Explain what you have done to research the problem If the first thing you do is ask a question without doing any research, you're lazy, and no one wants to help you. Using one of the many fine search engines you can most always find the answer to your problem. Sometimes you can't. Do yourself a favor - open a notepad app, and paste the URL's as you look them up. If you get your answer, don't save the note. If you don't get an answer, send the list along with the problem. It will show that you've tried, and also keep people from sending you links that you've already checked. This: "I read the fine manual, and it doesn't mention Operating System XYZ for some reason. Also, I checked the following links, but the instructions there didn't fix the problem: " Not this: <NULL> 4. Say "Please" and "Thank You" Remember, you're asking for help. No one owes you their valuable time. Ask politely, don't pester, endure the people who are rude to you, and when your question is answered, respond back to the thread or e-mail with a thank you to close it out. It helps others that have your same problem know that this is the correct answer. This: "I could really use some help here - if you have any pointers or things to try, I'd appreciate it." Not this: "I really need this done right now - why are there no responses?" This: "Thanks for those responses - that last one did the trick. Turns out I needed a new printer anyway, didn't realize they were so inexpensive now." Not this: <NULL> There are a lot of motivated people that will help you. Help them do that.

  • Strategies for invoking subclass methods on generic objects

    - by Brad Patton
    I've run into this issue in a number of places and have solved it a bunch of different ways but looking for other solutions or opinions on how to address. The scenario is when you have a collection of objects all based off of the same superclass but you want to perform certain actions based only on instances of some of the subclasses. One contrived example of this might be an HTML document made up of elements. You could have a superclass named HTMLELement and subclasses of Headings, Paragraphs, Images, Comments, etc. To invoke a common action across all of the objects you declare a virtual method in the superclass and specific implementations in all of the subclasses. So to render the document you could loop all of the different objects in the document and call a common Render() method on each instance. It's the case where again using the same generic objects in the collection I want to perform different actions for instances of specific subclass (or set of subclasses). For example (an remember this is just an example) when iterating over the collection, elements with external links need to be downloaded (e.g. JS, CSS, images) and some might require additional parsing (JS, CSS). What's the best way to handle those special cases. Some of the strategies I've used or seen used include: Virtual methods in the base class. So in the base class you have a virtual LoadExternalContent() method that does nothing and then override it in the specific subclasses that need to implement it. The benefit being that in the calling code there is no object testing you send the same message to each object and let most of them ignore it. Two downsides that I can think of. First it can make the base class very cluttered with methods that have nothing to do with most of the hierarchy. Second it assumes all of the work can be done in the called method and doesn't handle the case where there might be additional context specific actions in the calling code (i.e. you want to do something in the UI and not the model). Have methods on the class to uniquely identify the objects. This could include methods like ClassName() which return a string with the class name or other return values like enums or booleans (IsImage()). The benefit is that the calling code can use if or switch statements to filter objects to perform class specific actions. The downside is that for every new class you need to implement these methods and can look cluttered. Also performance could be less than some of the other options. Use language features to identify objects. This includes reflection and language operators to identify the objects. For example in C# there is the is operator that returns true if the instance matches the specified class. The benefit is no additional code to implement in your object hierarchy. The only downside seems to be the lack of using something like a switch statement and the fact that your calling code is a little more cluttered. Are there other strategies I am missing? Thoughts on best approaches?

  • Getting Started with Cloud Computing

    - by juanlarios
    You’ve likely heard about how Office 365 and Windows Intune are great applications to get you started with Cloud Computing. Many of you emailed me asking for more info on what Cloud Computing is, including the distinction between "Public Cloud" and "Private Cloud". I want to address these questions and help you get started. Let's begin with a brief set of definitions and some places to find more info; however, an excellent place where you can always learn more about Cloud Computing is the Microsoft Virtual Academy. Public Cloud computing means that the infrastructure to run and manage the applications users are taking advantage of is run by someone else and not you. In other words, you do not buy the hardware or software to run your email or other services being used in your organization – that is done by someone else. Users simply connect to these services from their computers and you pay a monthly subscription fee for each user that is taking advantage of the service. Examples of Public Cloud services include Office 365, Windows Intune, Microsoft Dynamics CRM Online, Hotmail, and others. Private Cloud computing generally means that the hardware and software to run services used by your organization is run on your premises, with the ability for business groups to self-provision the services they need based on rules established by the IT department. Generally, Private Cloud implementations today are found in larger organizations but they are also viable for small and medium-sized businesses since they generally allow an automation of services and reduction in IT workloads when properly implemented. Having the right management tools, like System Center 2012, to implement and operate Private Cloud is important in order to be successful. So – how do you get started? The first step is to determine what makes the most sense to your organization. The nice thing is that you do not need to pick Public or Private Cloud – you can use elements of both where it makes sense for your business – the choice is yours. When you are ready to try and purchase Public Cloud technologies, the Microsoft Volume Licensing web site is a good place to find links to each of the online services. In particular, if you are interested in a trial for each service, you can visit the following pages: Office 365, CRM Online, Windows Intune, and Windows Azure. For Private Cloud technologies, start with some of the courses on Microsoft Virtual Academy and then download and install the Microsoft Private Cloud technologies including Windows Server 2008 R2 Hyper-V and System Center 2012 in your own environment and take it for a spin. Also, keep up to date with the Canadian IT Pro blog to learn about events Microsoft is delivering such as the IT Virtualization Boot Camps and more to get you started with these technologies hands on. Finally, I want to ask for your help to allow the team at Microsoft to continue to provide you what you need. Twice a year through something we call "The Global Relationship Study" – they reach out and contact you to see how they're doing and what Microsoft could do better. If you get an email from "Microsoft Feedback" with the subject line "Help Microsoft Focus on Customers and Partners" between March 5th and April 13th, please take a little time to tell them what you think. Cloud Computing Resources: Microsoft Server and Cloud Computing site – information on Microsoft's overall cloud strategy and products. Microsoft Virtual Academy – for free online training to help improve your IT skillset. Office 365 Trial/Info page – get more information or try it out for yourself.

  • Network outside internal not reaching TMG Forefront 2010 (Hyper-V environment)

    - by Pascal
    Below is my environment: I have 1 physical machine running Windows 2008 R2, with the Hyper-V role. This machine has 3 physical NICs: One for Internet One for Internal Network One for Wireless Network All 3 have their respective Virtual Networks in Hyper-V, and I have an extra Private virutal machine network for a DMZ Network. In one of the virtual machines, I have TMG Forefront 2010 SP1 installed, with all 4 networks available to it.

  • Creating a Sharepoint Development Environment from an Existing Production Environment

    - by Starky
    I have very little experience using Sharepoint but a good amount using Visual Studio 2008, SQL Server 2005, Windows Server 2003 and IIS6. I need to create a development environment for a SharePoint 2007 system that will be used internally. The system is already deployed over two servers - one of the servers simply holds the database and everything else is on the other server. We are also using WSS 3.0. I have created a Virtual Machine with all the required software including a clean installation of SharePoint Server 2007 and I wish to use this single Virtual Machine as the development environment. Right now there are no custom assemblies being used on the production server as far as I am aware. There are 3 websites, one over port 80 for user accesss, one over a custom port for central administration, and one over another custom port. Not sure what the last one is for but my blank instance of Sharepoint on my Virtual Machine also has something similar. I attempted to use the STSADM tool to backup and restore these 3 sites from my production environment to my development environment and while the operations completed succesfully, the central administration site in my development environment acted strangely and I could not access port 80 - I did not seem to have correct credentials for it. I suspected that it would not have been so simple so could I please have advice on how to create my development environment so that I can use it to deploy updates to the production one.

  • Nhibernate Guid with PK MySQL

    - by Andrew Kalashnikov
    Hello colleagues. I've got a question. I use NHibernate with MySql. At my entities I use Id(PK) for my business-logic usage and Guid(for replication). So my BaseDomain: public class BaseDomain { public virtual int Id { get; set; } public virtual Guid Guid { get; set; } public class Properties { public const string Id = "Id"; public const string Guid = "Guid"; } public BaseDomain() { } } My usage domain: public class ActivityCategory : BaseDomain { public ActivityCategory() { } public virtual string Name { get; set; } public new class Properties { public const string Id = "Id"; public const string Guid = "Guid"; public const string Name = "Name"; private Properties() { } } } Mapping: <class name="ActivityCategory, Clients.Core" table='Activity_category'> <id name="Id" unsaved-value="0" type="int"> <column name="Id" not-null="true"/> <generator class="native"/> </id> <property name="Guid"/> <property name="Name"/> </class> But when I insert my entity: [Test] public void Test() { ActivityCategory ac = new ActivityCategory(); ac.Name = "Test"; using (var repo = new Repository<ActivityCategory>()) repo.Save(ac); } I always get '00000000-0000-0000-0000-000000000000' at my Guid field. What should I do for generate right Guid. May be mapping? Thanks a lot!

  • PrintableArea in C# - Bug?

    - by Brandi
    I am having an issue with PageSettings.PrintableArea's width and height values. Width, Height, and Size properties claim to "get or set" the values. Also, the inflate() function claims to change the size based on values passed in. However, all of these attempts to change the value have not worked. Inflate() is ignore (no error, just passes as if it worked, but the values remain unchanged. Attempting to set the height, width, or size gives a compiler error: "Cannot modify the return value of 'System.Drawing.Printing.PageSettings.PrintableArea' because it is not a variable". I get the feeling that this means the "or set" part of the description is a lie. Why I want to know this: (Someone always asks...) I have a printing application (C#, WinForm) that for most things is working rather well. I can set the printer settings and page settings objects to control what displays in the print dialog's printer properties. However, with Microsoft Office Document Image Writer, these settings are sometimes ignored, and the paper size returns as 0, 0 even when it displayed something else. All I really want it for it to be WYSIWYG as far as the displayed values go, so I change the paper size back to what it should be, but the printable area, if it is wrong, makes the resulting image wonky. The resulting image is the size of the printable area instead of the value in papersize. Just wondering if there was a reason for this or a way to get it not to do that. Thanks in advance. :)

  • Mapping interface or abstract class component

    - by Yann Trevin
    Please consider the following simple use case: public class Foo { public virtual int Id { get; protected set; } public virtual IBar Bar { get; set; } } public interface IBar { string Text { get; set; } } public class Bar : IBar { public virtual string Text { get; set; } } And the fluent-nhibernate map class: public class FooMap : ClassMap<Foo> { public FooMap() { Id(x => x.Id); Component(x => x.Bar, m => { m.Map(x => x.Text); }); } } While running any query with configuration, I get the following exception: NHibernate.InstantiationException: "Cannot instantiate abstract class or interface: NHMappingTest.IBar" It seems that NHibernate tries to instantiate an IBar object instead of the Bar concrete class. How to let Fluent-NHibernate know which concrete class to instantiate when the property returns an interface or an abstract base class? EDIT: Explicitly specify the type of component by writing Component<Bar> (as suggested by Sly) has no effect and causes the same exception to occur. EDIT2: Thanks to vedklyv and Paul Batum: such a mapping should be soon is now possible.

  • How to read a Website's Directory Structure using WMI and C# in IIS 6.0?

    - by Steve Johnson
    Hi all, I need to read a website's folders using WMI and C# in IIS 6.0. I am able to read the Virtual directories and applications using the "IISWebVirtualDirSetting" class. However the physical folders located inside a website cannot be read using this class. And for my case i need to read sub folders located within a website and later on set permission on them. For my requirement i dont need to work on Virtual Directories/Web Service Applications (which can be easily obtained using the code below..). I have tried to use IISWebDirectory class but it has been useful. Here is the code that reads IIS Virtual Directories... public static ArrayList RetrieveVirtualDirList(String ServerName, String WebsiteName) { ConnectionOptions options = SetUpAuthorization(); ManagementScope scope = new ManagementScope(string.Format(@"\\{0}\root\MicrosoftIISV2", ServerName), options); scope.Connect(); String SiteId = GetSiteIDFromSiteName(ServerName, WebsiteName); ObjectQuery OQuery = new ObjectQuery(@"SELECT * FROM IISWebVirtualDirSetting"); //ObjectQuery OQuery = new ObjectQuery(@"SELECT * FROM IIsSetting"); ManagementObjectSearcher WebSiteFinder = new ManagementObjectSearcher(scope, OQuery); ArrayList WebSiteListArray = new ArrayList(); ManagementObjectCollection WebSitesCollection = WebSiteFinder.Get(); String WebSiteName = String.Empty; foreach (ManagementObject WebSite in WebSitesCollection) { WebSiteName = WebSite.Properties["Name"].Value.ToString(); WebsiteName = WebSiteName.Replace("W3SVC/", ""); String extrctedSiteId = WebsiteName.Substring(0, WebsiteName.IndexOf('/')); String temp = WebsiteName.Substring(0, WebsiteName.IndexOf('/') + 1); String VirtualDirName = WebsiteName.Substring(temp.Length); WebsiteName = WebsiteName.Replace(SiteId, ""); if (extrctedSiteId.Equals(SiteId)) //if (true) { WebSiteListArray.Add(VirtualDirName ); //WebSiteListArray.Add(WebSiteName); //+ "|" + WebSite.Properties["Path"].Value.ToString() } } return WebSiteListArray; } Kindly help in this regard. Thanks you.

  • Fancybox "close" hangs/delays in IE7/8

    - by Kerri
    I'm having an issue with IE7/8 only on a development site: when closing the Fancybox, there is a major delay, sometimes about ten seconds or so, sometimes much longer (like a minute). Some things that might be relevant: • Using fancybox 1.3.1 • Works perfectly on all other browsers (FF, Safari, Opera, Chrome) • The loaded iframe contains a flash "virtual tour" • There are no errors reported in IE's Dev Toolbar or in DebugBar • The fancybox renders perfectly in IE, and after it has closed, there is not a problem loading it again. The closing seems to be the only issue. (That, and that it crashed the client's browser once, but I'm inclined to believe that had more to do with the content of the iframe than fancybox). I changed the link to the iFrame to something simpler (google), and it closed with no problem. So it does seem to have something to do with a conflict with the content of the iframe. The call: $("a#tourbox").fancybox({ "width": 750, "height" : 575, "autoScale": false, "type": "iframe" }); The HTML: <a id="tourbox" href="http://tour.circlepix.com/tour.htm?id=670335"><img src="sites/all/themes/removed/images/banquets-vtour.jpg" alt="Virtual Tour" /></a> Here's a link to the page with the problem: http://s93571.gridserver.com/banquets Click on the "Go to 360° Virtual Tour" image. Here's the page it loads: http://tour.circlepix.com/tour.htm?id=670335 I'd greatly appreciate any clues or ideas of what might be the issue. I couldn't find any other discussions with a similar problem. Thanks for any insights!

  • Quartz compositions created in Snow Leopard (10.6) doesn't work in Leopard (10.5) despite testing in

    - by adib
    Hi I have a reasonably advanced (many patches and subpatches) quartz composition that was created in Snow Leopard but doesn't run well (many elements are not rendered) in Leopard. The composition tested OK via Quartz Composer's Test in Runtime option and works fine for both Leopard 32-bits and Leopard 64-bits (menu item "File | Test in Runtime | Leopard 32-bits". In an actual Leopard (32-bits) system, a lot of elements are not rendered in the quartz composition. Below are the log file excerpt when the composition is run in QuickTime Player under Leopard: QuickTime Player[134] *** <QCNodeManager | namespace = "com.apple.QuartzComposer" | 335 nodes>: Patch with name "/units to pixels" is missing QuickTime Player[134] *** Message from <QCPatch = 0x06D82880 "(null)">:Cannot create node of class "/units to pixels" and identifier "(null)" QuickTime Player[134] *** Message from <QCPatch = 0x06D7C130 "(null)">:Cannot create node of class "/resize image to target" and identifier "(null)" QuickTime Player[134] *** Message from <QCPatch = 0x06D7C130 "(null)">:Cannot create connection from ["outputValue" @ "Math_1"] to ["Target_Pixels" @ "Patch_2"] The patch "units to pixels" is a system patch in Snow Leopard whereas the patch "resize image to target" is a custom virtual patch located in my home directory. It seems that we can cross out problems in which the composition is referencing a missing virtual patch. I have tested the composition under another user's account and it ran fine which shows that it already embeds the "resize image to target" virtual patch that is located in my home directory. I'm really puzzled why the composition passes the Leopard Runtime test but yet fail to run in an actual Leopard OS? Is there a post-processing step that I need to run to the composition file? Is there any way to make this patch more compatible with Leopard? Thanks in advance.

  • Inherited fluent nhibenate mapping issue

    - by Aim Kai
    I have an interesting issue today!! Basically I have two classes. public class A : B { public virtual new ISet<DifferentItem> Items {get;set;} } public class B { public virtual int Id {get;set;} public virtual ISet<Item> Items {get;set;} } The subclass A hides the base class B property, Items and replaces it with a new property with the same name and a different type. The mappings for these classes are public class AMapping : SubclassMap<A> { public AMapping() { HasMany(x=>x.Items) .LazyLoad() .AsSet(); } } public class BMapping : ClassMap<B> { public BMapping() { Id(x=>x.Id); HasMany(x=>x.Items) .LazyLoad() .AsSet(); } } However when I run my unit test to check the mapping I get the following exception: Tests the A mapping: NHibernate.PropertyAccessException : Invalid Cast (check your mapping for property type mismatches); setter of A ---- System.InvalidCastException : Unable to cast object of type 'NHibernate.Collection.Generic.PersistentGenericSet1[Item]' to type 'Iesi.Collections.Generic.ISet1[DifferentItem]'. Anyone have any ideas? Clearly it is something to do with the type of the collection on the sub-class. But I skimmed through the available options on the mapping class and nothing stood out as being the solution here.

  • resolving overloads in boost.python

    - by swarfrat
    I have a C++ class like this: class ConnectionBase { public: ConnectionBase(); template <class T> Publish(const T&); private: virtual void OnEvent(const Overload_a&) {} virtual void OnEvent(const Overload_b&) {} }; My templates & overloads are a known fixed set of types at compile time. The application code derives from ConnectionBase and overrides OnEvent for the events it cares about. I can do this because the set of types is known. OnEvent is private because the user never calls it, the class creates a thread that calls it as a callback. The C++ code works. I have wrapped this in boost.python, I can import it and publish from python. I want do create the equivalent of the following in python : class ConnectionDerived { public: ConnectionDerived(); private: virtual void OnEvent(const Overload_b&) { // application code } }; But ... since python isn't typed, and all the boost.python examples I've seen dealing with internals are on the C++ side, I'm a little puzzled as to how to do this. How do I override specific overloads?

  • Is there a more easy way to create a WCF/OData Data Service Query Provider?

    - by routeNpingme
    I have a simple little data model resembling the following: InventoryContext { IEnumerable<Computer> GetComputers() IEnumerable<Printer> GetPrinters() } Computer { public string ComputerName { get; set; } public string Location { get; set; } } Printer { public string PrinterName { get; set; } public string Location { get; set; } } The results come from a non-SQL source, so this data does not come from Entity Framework connected up to a database. Now I want to expose the data through a WCF OData service. The only way I've found to do that thus far is creating my own Data Service Query Provider, per this blog tutorial: http://blogs.msdn.com/alexj/archive/2010/01/04/creating-a-data-service-provider-part-1-intro.aspx ... which is great, but seems like a pretty involved undertaking. The code for the provider would be 4 times longer than my whole data model to generate all of the resource sets and property definitions. Is there something like a generic provider in between Entity Framework and writing your own data source from zero? Maybe some way to build an object data source or something, so that the magical WCF unicorns can pick up my data and ride off into the sunset without having to explicitly code the provider?

    I'm writing a printing routing in C#, using the .NET PrintDocument class, handling the OnPrintPage event. I've managed to maximize the margins and print the Image in landscape mode, but it simply does not look as good as when I print the same image file from Windows Photo Gallery (formerly Windows Picture and Fax Viewer), the default image preview program in Windows Vista. I noticed an option there for selecting "Sharpen Image for Printing", but what does that do? I've thought about printing copies of the image from Windows Photo Gallery first, then sending the sheets through the printer a second time to print the custom overlays I need, but it's hard to make it line up every time, since the printer sucks the sheet in without the kind of precision I need... so I really need to do ALL the drawing commands within C#, including the image. Does anyone know how to perform pre-processing on the bitmap so that it prints as nicely as Windows Photo Gallery does it? Are there any simple print drivers that can intercept Photo Gallery printing output as a standard image file (bmp, png, etc.) that can be read by the .NET Image class? I'm all for creativity here.

  • Making .NET assembly COM-visible and working for VB5

    - by Cyberherbalist
    I have an assembly which I have managed to make visible to VB6 and it works, but having a problem accomplishing the same thing with VB5. For VB6, I have built the assembly, made it COM-visible, registered it as a COM object etc., and the assembly shows in VB6's References list, and allows me to use it successfully. The Object Browser also shows the method in the assy. I copied the assembly and its TLB to a virtual workstation used for VB5 development, and ran Regasm, apparently successfully: C:\>C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727 \regasm arserviceinterface.dll /tlb:arserviceinterface.tlb Microsoft (R) .NET Framework Assembly Registration Utility 2.0.50727.3053 Copyright (C) Microsoft Corporation 1998-2004. All rights reserved. Assembly exported to 'C:\Projects\AR\3rd Party\ARService\arserviceinterface.tlb' , and the type library was registered successfully Note that the virtual W/S is Win2k and does not have .NET Fx 3.5 on it, just 2.0. The assembly shows up in the References that can be selected in VB5, but the method of the assembly doesn't show up in the Object Browser, and it is generally unusable. Either there is a step to do that I haven't done, or VB5 doesn't know how to use such a COM object. Note that the VB5 setup is on a virtual workstation, not the same workstation that VB6 is installed on. Any ideas? One thing that occurred to me is that I might need to generate and use a strong name on the workstation in question, but...

  • How to query collections in NHibernate

    - by user305813
    Hi, I have a class: public class User { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual IDictionary<string, string> Attributes { get; set; } } and a mapping file: <class name="User" table="Users"> <id name="Id"> <generator class="hilo"/> </id> <property name="Name"/> <map name="Attributes" table="UserAttributes"> <key column="UserId"/> <index column="AttributeName" type="System.String"/> <element column="Attributevalue" type="System.String"/> </map> </class> So now I can add many attributes and values to a User. How can I query those attributes so I can get ie. Get all the users where attributename is "Age" and attribute value is "20" ? I don't want to do this in foreach because I may have millions of users each having its unique attributes. Please help
