  • Fluent NHibernate Self Referencing Many To Many

    - by Jeremy
    I have an entity called Books that can have a list of more books called RelatedBooks. The abbreviated Book entity looks something likes this: public class Book { public virtual long Id { get; private set; } public virtual IList<Book> RelatedBooks { get; set; } } Here is what the mapping looks like for this relationship HasManyToMany(x => x.RelatedBooks) .ParentKeyColumn("BookId") .ChildKeyColumn("RelatedBookId") .Table("RelatedBooks") .Cascade.SaveUpdate(); Here is a sample of the data that is then generated in the RelatedBooks table: BookId RelatedBookId 1 2 1 3 The problem happens when I Try to delete a book. If I delete the book that has an ID of 1, everything works ok and the RelatedBooks table has the two corresponding records removed. However if I try to delete the book with an ID of 3, I get the error "The DELETE statement conflicted with the REFERENCE constraint "FK5B54405174BAB605". The conflict occurred in database "Test", table "dbo.RelatedBooks", column 'RelatedBookId'". Basically what is happening is the Book cannot be deleted because the record in the RelatedBooks table that has a RelatedBookId of 3 is never deleted. How do I get that record to be deleted when I delete a book? EDIT After changing the Cascade from SaveUpdate() to All(), the same problem still exists if I try to delete the Book with an ID of 3. Also with Cascade set to All(), if delete the Book with and ID of 1, then all 3 books (ID's: 1, 2 and 3) are deleted so that won't work either. Looking at the SQL that is executed when the Book.Delete() method is called when I delete the Book with an ID of 3, it looks like the SELECT statement is looking at the wrong column (which I assume means that the SQL DELETE statment would make the same mistake, therefore never removing that record). Here is the SQL for the RelatedBook SELECT relatedboo0_.BookId as BookId3_ , relatedboo0_.RelatedBookId as RelatedB2_3_ , book1_.Id as Id14_0_ FROM RelatedBooks relatedboo0_ left outer join [Book] book1_ on relatedboo0_.RelatedBookId=book1_.Id WHERE relatedboo0_.BookId=3 The WHERE statment should look something like this for thie particular case: WHERE relatedboo0_.RelatedBookId = 3 SOLUTION Here is what I had to do to get it working for all cases Mapping: HasManyToMany(x => x.RelatedBooks) .ParentKeyColumn("BookId") .ChildKeyColumn("RelatedBookId") .Table("RelatedBooks"); Code: var book = currentSession.Get<Book>(bookId); if (book != null) { //Remove all of the Related Books book.RelatedBooks.Clear(); //Get all other books that have this book as a related book var booksWithRelated = currentSession.CreateCriteria<Book>() .CreateAlias("RelatedBooks", "br") .Add(Restrictions.Eq("br.Id", book.Id)) .List<Book>(); //Remove this book as a Related Book for all other Books foreach (var tempBook in booksWithRelated) { tempBook.RelatedBooks.Remove(book); tempBook.Save(); } //Delete the book book.Delete(); }

  • Does Windows 8 RTM Support VB6 (SP6) Runtime files? If so, which ones?

    - by user51047
    Basically, I'm trying to find out which of the following files come packaged with the Windows 8 RTM (that is, the final version). Just to be clear, we're not wanting to know if any of the runtime files (listed below) are or were included with any of the previous versions (Beta, CTP, RS etc) or releases of Windows 8 - we are just interested in this compatibility question as far as Windows 8 RTM (Final Version) is concerned. In addition, if possible, we would also like to know which of the below files (if any) come shipped and registered with the Windows 8 RT (on ARM) version. As far as the ARM version is concerned, you're welcome to base your answer on the latest version of Windows 8 RT (on ARM) that is available at the date and time your answer is posted. (This will also serve to future-proof this question as additional releases or versions of Windows 8 and Windows 8 RT on ARM come out). Here are the list of files (which are basically the VB6 SP6 runtime files): File name Version Size Asycfilt.dll 2.40.4275.1 144 KB (147,728 bytes) Comcat.dll 4.71.1460.1 21.7 KB (22,288 bytes) Msvbvm60.dll 6.0.97.82 1.32 MB (1,386,496 bytes) Oleaut32.dll 2.40.4275.1 584 KB (598,288 bytes) Olepro32.dll 5.0.4275.1 160 KB (164,112 bytes) Stdole2.tlb 2.40.4275.1 17.5 KB (17,920 bytes) Of course, the most important file in there is MSVBVM60.DLL, so if you cannot provide details for all files relating to both Windows Releases, then basing the answer on as many of the files possible would also be useful. Thank you for reading and for your anticipated assistance in putting this question/answer on record.

  • IE9 will not navigate to some websites but Google Chrome can

    - by Storchburp
    Was recommended by a friend to ask for help here. I am using Internet Explorer 9. As of two days ago I was suddenly unable to navigate to any part of the following websites: www.computerandvideogames.com www.deviantart.com www.cnet.com However I can still access all of them normally through Google Chrome. I am on a college network but these sites are also accessible through fixed terminals provided by the school and are definitely not blocked. I do not know of any other sites similarly affected. There is no popup, no error message, no diversion to a site telling me I can't access / am blocked etc. I can be on www.google.com and attempt to access these sites through the URL or google search, and my cursor will just show the little moving blue wheel next to the arrow for a couple of seconds, and the page displayed on my browser will not change; ie. not navigating at all. Running antivirus software, changing proxy settings in IE, clearing cookies, unplugging/plugging in computer, restarting PC etc have not changed the situation. Any assistance or advice would be greatly appreciated. Thanks in advance.

  • How to upload a huge(GBs) file to a webserver

    - by Aman Jain
    Hi I want to create a web interface that will allow users to upload huge files. These files are actually vmdk files(Virtual Machine Disks), and they can be multi GB in size. I think this makes the situation different from normal file uploads(10-20MB file uploads). So any advise on how to achieve the same in an efficient and fault tolerant way, is appreciated. Thanks Aman Jain

  • OSX: Mimic Ubuntu IP Masquerading via iptables with ipfw

    - by Dogbert
    Good day, I am attempting to replicate a setup I have between a router and an Ubuntu PC, and have the same setup working on my MacBook (10.6, Snow Leopard). First, I have a router that has a USB port. When I plug it into my Ubuntu PC, it creates an RNDIS connection, allowing me to connect to the router over the USB cable via an IP connection. When I plug it into my computer via USB, it gets assigned an IP address of 172.16.84.1, and a new adapter appears when I type ifconfig. I can then SSH into the device via ssh [email protected]. When I log in to the device, I flush the routes, then create the default route: admin@localhost> route -f admin@localhost> route add default 172.16.84.2 Now, in my Ubuntu machine, I use iptables to enable IP masquerading: root@Valhalla> sudo iptables -t nat -A POSTROUTING -s 172.16.84.2 -j MASQUERADE Once this is all done, the router has internet access over the USB connection to my PC. I am trying to replicate this exact setup on my MacBook now (Snow Leopard), but iptables does not exist for OSX, not even a Macports version exists. I have scoured through other questions on StackOverflow that cover the usage of the ipfw command, which apparently works as a drop-in replacement for iptables. However, the syntax is significantly different, and I'm pretty much lost. Does anyone with some experience with ipfw have some suggestions on how I could accomplish this and create a NAT connection via IP masquerading like I could with my Ubuntu PC? Thank you for your assistance.

  • SocketException (Timeout) only when running as scheduled task

    - by BVartin
    I'm running a C# web-scrapper application (that I wrote) on a Windows Server 2003 instance under a user belonging to the local Administrator group. When I run it within a desktop/remote-desktop session the application runs successfully but when I schedule it to run under the same user/security-context outside of the desktop session, all socket connections timeout. The scheduled task calls a batch file which in-turn calls the application. The Windows Server 2003 instance has a very basic configuration and isn't even connected to a domain. I cannot find anything in any firewall or security configuration which is preventing this but maybe I have overlooked something, can anyone be of any assistance? System.Net.WebException: Unable to connect to the remote server --- System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond X.X.X.X:443 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception) --- End of inner exception stack trace --- at System.Net.HttpWebRequest.GetResponse()

  • Fluent | Nhibernate multiple inheritance mapping?

    - by Broken Pipe
    I'm trying to map this classes: public interface IBusinessObject { Guid Id { get; set; } } public class Product { public virtual Guid Id { get; set; } public virtual int ProductTypeId { get; set; } } public class ProductWeSell : Product, IBusinessObject { } public class ProductWeDontSell : Product { } Using this Fluent mapping code: public class IBusinessObjectMap : ClassMap<IBusinessObject> { public IBusinessObjectMap() { Id(t => t.Id).GeneratedBy.Guid(); Table("BusinessObject"); } } public class ProductMap : ClassMap<Product> { public ProductMap() { Id(t => t.Id); DiscriminateSubClassesOnColumn("ProductTypeId", "null").Nullable(); } } public class ProductWeSellMap : SubclassMap<ProductWeSell> { public ProductWeSellMap() { DiscriminatorValue(1); KeyColumn("Id"); } } public class ProductWeDontSellMap : SubclassMap<ProductWeDontSell> { public ProductWeDontSellMap() { DiscriminatorValue(2); KeyColumn("Id"); } } But I get {"Duplicate class/entity mapping ProductWeSell"} error. And if we take a look at generated HBM, indeed it's duplicated, but i have no idea how to write this mapping without duplicating it if it's possible at all. Produced hbm: <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class xmlns="urn:nhibernate-mapping-2.2" name="IBusinessObject" table="BusinessObject"> <joined-subclass name="ProductWeSell" table="ProductWeSell"/> </class> </hibernate-mapping> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class xmlns="urn:nhibernate-mapping-2.2" discriminator-value="null" name="Product" table="Product"> <discriminator type="String"> <column name="ProductTypeId" not-null="false" /> </discriminator> <subclass name="ProductWeDontSell" discriminator-value="2" /> <subclass name="ProductWeSell" discriminator-value="1" /> </class> </hibernate-mapping> So far I was unable to figure out how to map this using fluent Nhibernate (i haven't tried mapping this using hmb files). Any help appreciated Fluent or HBM files. The thing I'm trying to solve look identical to this topic: NHibernate inheritance mapping question

  • Ruby generic filesystem libraries

    - by webdestroya
    I am looking for a "Virtual File System" type library for ruby. I want to be able to have a completely generic file system that I can easily switch between using Local files and using S3 or using FTP or something like that. (Identical to VFS for Java) Has anybody used any type of generic file system for ruby (I just need it to support local files and Amazon S3) Any pointers would be much appreciated.

  • How to boot linux direct to application on console with no login

    - by amanda
    I have a need to start an application on bootup on the linux console and I do not have a need for any type of login or security. I do not need any ALT-F1,F2,etc virtual consoles but I would like to allow SSH access via the network port for debugging, loading, etc. The application is a SDL graphics program running with fbcon as the SDL_VIDEODRIVER if that matters. I'm currently using Fedora 10 and 12 but any distro that supports SDL using the fbcon framebuffer would be acceptable.

  • Is there a small business router that shows bandwidth usage graphs in the admin panel?

    - by Robert Drake
    I support a large number of public libraries that are having their networks upgraded in response to a grant application. These libraries are generally home to between 6-15 computers and have little or no tech services either onsite or contracted remotely. In order to justify current and future purchases, a number of the libraries have requested routers that can provide bandwidth usage graphs that they can show to their managing boards. Is there a small business router that displays traffic graphs in the router administration web interface? The router needs to suppport DHCP and basic firewalling. No other features are required. Further, the reports just need to show overall trends. It is not necessary to show traffic by IP, by protocol/application, or by time of day. They just need an overall week to week, month to month, trend line. I'm familiar with MRTG/PRTG/tools that collect SNMP data from the router, but the libraries don't have the expertise for the configuration. I've considered installing the tomato firmware on some cheap home/home office routers, but if there's a commercial product that can be purchased that would be significantly simpler. Also the library boards would be much more likely to approve the purchase of a commercial product over a 'hacked' one. Any assistance would be appreciated.

  • boost::asio buffer impossible to convert parameter from char to const mutable_buffer&

  • PHP 5.3.5 Windows installer missing php_ldap.dll

    - by nmjk
    I'm working with Windows Server 2008, Apache 2.2. I'm using php-5.3.5-Win32-VC6-x86.msi as the installer, using the threadsafe version. I've gone through the install process four or five times just to make sure that I'm not missing anything ridiculous, but I don't think I am. The problem is that the php_ldap.dll extension simply doesn't seem to exist. It's not present in the installer interface (where the user is asked to choose which extensions to install), and it definitely doesn't appear in the ext/ directory after install. I found a lot of mentions of this issue for 5.3.3, including links to download the extension individually. Those links no longer exist, of course, and besides: they were for 5.3.3. I'd really rather use an extension that belongs with PHP 5.3.5. Anyone else encounter this problem? Any ideas as to what's going wrong? Anyone seen acknowledgement by the PHP folks that the file is indeed missing, and that it's an oversight? It's quite a frustration because the server I'm building has no purpose if I don't have PHP LDAP support. Cheers all, and thanks in advance for your assistance.

  • Win7 Aero disabled due to mirror drivers following TightVNC use, cannot re-enable

    - by me_and
    I recently installed TightVNC, and used it to access my desktop from my phone. When I did so, my desktop reported that Aero had been disabled due to an application being run that didn't support it. I now cannot re-enable Aero, despite having closed the TightVNC server (and indeed having rebooted a number of times since). Windows 7 troubleshooting reports the following: Close programs using mirror drivers To allow Aero effects to be displayed, close any programs that use mirror drivers (a type of display driver), such as Windows Remote Assistance and Windows Live Mesh. The troubleshooting system appears to attempt to automatically fix that, but fails. I can see nothing in the task manager that obviously uses mirror drivers; in particular, I can see nothing that looks like TightVNC in there. Starting and exiting TightVNC makes no difference. Google has turned up nothing that looks useful so far, either, although my Google-fu isn't great and I may just be searching for the wrong things. There's another question that reports the same problem, caused by LogMeIn rather than TightVNC, but the solution listed there doesn't work—TightVNC doesn't install LogMeIn mirror drivers, for obvious reasons.

  • TVirtualStringTree - resetting non-visual nodes and memory comsumption

    - by Remy Lebeau - TeamB
    I have an app that loads records from a binary log file and displays them in a virtual TListView. There are potentially millions of records in a file, and the display can be filtered by the user, so I do not load all of the records in memory at one time, and the ListView item indexes are not a 1-to-1 relation with the file record offsets (List item 1 may be file record 100, for instance). I use the ListView's OnDataHint event to load records for just the items the ListView is actually interested in. As the user scrolls around, the range specified by OnDataHint changes, allowing me to free records that are not in the new range, and allocate new records as needed. This works fine, speed is tolerable, and the memory footprint is very low. I am currently evaluating TVirtualStringTree as a replacement for the TListView, mainly because I want to add the ability to expand/collapse records that span multiple lines (I can fudge it with the TListView by incrementing/decrementing the item count dynamically, but this is not as straight forward as using a real tree). For the most part, I have been able to port the TListView logic and have everything work as I need. I notice that TVirtualStringTree's virtual paridigm is vastly different, though. It does not have the same kind of OnDataHint functionality that TListView does (I can use the OnScroll event to fake it, which allows my memory buffer logic to continue working), and I can use the OnInitializeNode event to associate nodes with records that are allocated. However, once a tree node is initialized, it sees that it remains initialized for the lifetime of the tree. That is not good for me. As the user scrolls around and I remove records from memory, I need to reset those non-visual nodes without removing them from the tree completely, or losing their expand/collapse states. When the user scrolls them back into view, I can re-allocate the records and re-initialize the nodes. Basically, I want to make TVirtualStringTree act as much like TListView as possible, as far as its virtualization is concerned. I have seen that TVirtualStringTree has a ResetNode() method, but I encounter various errors whenever I try to use it. I must be using it wrong. I also thought of just storing a data pointer inside each node to my record buffers, and I allocate and free memory, update those pointers accordingly. The end effect does not work so well, either. Worse, my largest test log file has ~5 million records in it. If I initialize the TVirtualStringTree with that many nodes at one time (when the log display is unfiltered), the tree's internal overhead for its nodes takes up a whopping 260MB of memory (without any records being allocated yet). Whereas with the TListView, loading the same log file and all the memory logic behind it, I can get away with using just a few MBs. Any ideas?

  • OpenVPN Client timing out

    - by Austin
    I recently installed OpenVPN on my Ubuntu VPS. Whenenver I try to connect to it, I can establish a connection just fine. However, everything I try to connect to times out. If I try to ping something, it will resolve the IP, but will time out after resolving the IP. (So DNS Server seems to be working correctly) My server.conf has this relevant information (At least I think it's relevant. I'm not sure if you need more or not) # Which local IP address should OpenVPN # listen on? (optional) ;local a.b.c.d # Which TCP/UDP port should OpenVPN listen on? # If you want to run multiple OpenVPN instances # on the same machine, use a different port # number for each one.

  • What are the recommended BEST CASE hardware requirements for TFS 2010

    - by Doug
    Hi guys, i have installed TFS 2010 in a 2 server setup with an App Tier server and a SQL Server and am not 100% happy with the performance. Both are running in VM's on SAN disks and have been given the following virtual hardware each: Windows 2008 R2 1 CPU @ 2.8Ghz 2gb RAM what should i lift - neither machine is hammered but both do go up to 80% when people are doing things on them - should i add another CPU to each - usually this is now required in a VMWARE setup but i don't know if TFS 2010 takes advantage of an extra core??? thank you in advance :-)

  • Juniper NetScreen NS-5GT traffic monitoring

    - by blah
    I've done casual research into the subject and am truly dismayed at the lack of compatible tools for such a simple task. Maybe someone can provide assistance. We have a NetScreen NS-5GT in the office. I need to be able to get a glance of current traffic per endpoint -- I think the equivalent of 'get sessions' with byte counts/rates. I don't care about bars, graphs, and reports. Something as simple as a classic software firewall display would be perfect. I can't shell out money on something real like SolarWinds products, so a free solution is essential. I'm willing to do a little work but refuse to program something from scratch. It's not prudent right now for me to install a hub or otherwise mess around physically. There must be something out there I can use, maybe in combination. I don't believe I'm asking too much. Specific answers only please, e.g. monitoring software you know will actually work with this antiquated device. I've read about general approaches to the broader problem dozens of times already.
