  • EF OrderBy method doesn't work with joins

    - by dudeNumber4
    Following works (ordered by name): from t in context.Table1.OrderBy( "it.Name" ) select t This doesn't work (no ordering): from t in context.Table1.OrderBy( "it.Name" ) join t2 in context.Table2 on t.SomeId equals t2.SomeId select t Nor does this (trying to reference the parent table to order): from t in context.Table1 join t2 in context.Table2.OrderBy( "it.Table1.Name" ) on t.SomeId equals t2.SomeId select t Nor does this (trying to order on the child table): from t in context.Table1 join t2 in context.Table2.OrderBy( "it.ChildName" ) on t.SomeId equals t2.SomeId select t How do I cause OrderBy not to be ignored while joining?

  • Getting started with terminal services (remote desktop services) and thin clients

    - by therulebookman
    I've got a Windows Server 2008 R2 box and I want to make it a RDS server and connect with thin clients. I don't want to do VDI with hyper-v, as this box is already virtualized. RDS is installed and I've installed an RDS CAL. I've browsed the Technet articles, but navigating technet is worthless. Can anyone point me to a concise get-me-started guide to terminal services/remote desktop services? If I can just get aimed in the right direction I can probably figure it out myself. Thanks.

  • How do I know which hardware components are compatible when building a computer?

    - by darkie15
    I am trying to setup my own new computer. I haven't done this before and hence needed guidance from all here. I can google out the results for steps to follow for setting up my machine, but I do not understand what components are compatible with each other? For example there must be specific models of motherboard that are compatible with Intel Core i5-2500K Sandy Bridge 3.3GHz. In general, if there is a website that can guide me on all compatible components, that would be great. If not, how would I be able to check compatibility?

  • Ruby tutorial for experienced programmers

    - by Skillwired
    I'm looking for a Ruby tutorial which would be usable for Java programmers with 8+ years of experience. I don't need another tutorial which explains basic programing/OOP/OOD concepts (inheritance, polymorphism, encapsulation, classes, constructors, hashes, etc.), just a fast-track tutorial (or even a reference?) which could tell us how to do specific things in Ruby.

  • HTML Purifier: Removing an element conditionally based on its attributes

    - by pinkgothic
    As per the HTML Purifier smoketest, 'malformed' URIs are occasionally discarded to leave behind an attribute-less anchor tag, e.g. <a href="javascript:document.location='http://www.google.com/'">XSS</a> becomes <a>XSS</a> ...as well as occasionally being stripped down to the protocol, e.g. <a href="http://1113982867/">XSS</a> becomes <a href="http:/">XSS</a> While that's unproblematic, per se, it's a bit ugly. Instead of trying to strip these out with regular expressions, I was hoping to use HTML Purifier's own library capabilities / injectors / plug-ins / whathaveyou. Point of reference: Handling attributes Conditionally removing an attribute in HTMLPurifier is easy. Here the library offers the class HTMLPurifier_AttrTransform with the method confiscateAttr(). While I don't personally use the functionality of confiscateAttr(), I do use an HTMLPurifier_AttrTransform as per this thread to add target="_blank" to all anchors. // more configuration stuff up here $htmlDef = $htmlPurifierConfiguration->getHTMLDefinition(true); $anchor = $htmlDef->addBlankElement('a'); $anchor->attr_transform_post[] = new HTMLPurifier_AttrTransform_Target(); // purify down here HTMLPurifier_AttrTransform_Target is a very simple class, of course. class HTMLPurifier_AttrTransform_Target extends HTMLPurifier_AttrTransform { public function transform($attr, $config, $context) { // I could call $this->confiscateAttr() here to throw away an // undesired attribute $attr['target'] = '_blank'; return $attr; } } That part works like a charm, naturally. Handling elements Perhaps I'm not squinting hard enough at HTMLPurifier_TagTransform, or am looking in the wrong place(s), or generally amn't understanding it, but I can't seem to figure out a way to conditionally remove elements. Say, something to the effect of: // more configuration stuff up here $htmlDef = $htmlPurifierConfiguration->getHTMLDefinition(true); $anchor = $htmlDef->addElementHandler('a'); $anchor->elem_transform_post[] = new HTMLPurifier_ElementTransform_Cull(); // add target as per 'point of reference' here // purify down here With the Cull class extending something that has a confiscateElement() ability, or comparable, wherein I could check for a missing href attribute or a href attribute with the content http:/. HTMLPurifier_Filter I understand I could create a filter, but the examples (Youtube.php and ExtractStyleBlocks.php) suggest I'd be using regular expressions in that, which I'd really rather avoid, if it is at all possible. I'm hoping for an onboard or quasi-onboard solution that makes use of HTML Purifier's excellent parsing capabilities. Returning null in a child-class of HTMLPurifier_AttrTransform unfortunately doesn't cut it. Anyone have any smart ideas, or am I stuck with regexes? :)

  • Attempting to migrate to Aptana from Dreamweaver - how to?

    - by Kerry
    I have been using Dreamweaver for years, and have used Dreamweaver MX, Dreamweaver MX 2004, Dreamweaver 8 & Dreamweaver CS4. They all carry a common theme and were relatively easy to migrate to each other. I use, however, very few features of dreamweaver. Specifically: Syntax highlighting Telesense FTP management/site management The search/replace The idea I get from Aptana is its much more geared toward the web development/programmer side of things, have better visualizations of classes, etc., and handle everything else just as well. The problem is it is not at all clear to me. I managed to start a new project, but it didn't associate it with an FTP. So, I created an FTP, and it looks like I can have many FTPs for one project. My question then is, is there a tutorial or guide to migrating to Aptana from a Dreamweavor's perspective?

  • Can I completely remove the Windows DNS in favour of BIND9 in an AD network?

    - by Vinícius Ferrão
    I would like to remove the DNS feature of Windows Domain Controllers and point the DNS servers to our BIND9 servers. I know it's possible to setup coexistence but this requires a number of extra Windows DNS Servers equals to the number of Domain Controllers in the network. Active Directory expects the _msdcs zone and other things like _tcp, _udp; etc. The main question is: how to make BIND9 takes care of all this AD specific data? And with dynamic updating to make AD even more happier. Thanks, PS: Making BIND9 points to the Windows DNS Servers to resolve the Active Directory specific zones isn't an option. We already do this... EDIT: As today, I'm running without Windows DNS. I'm writing up a guide on how to do this, and I'll update this topic.

  • Cannot Install JDK

    - by Vince
    For the life of me, I can't install the JDK on Windows Vista. I keep getting the error, "This Software Has Already Been Installed on Your Computer. Would you like to reinstall it?" Problem is, it's evidently not on my computer, since I can't a) run Eclipse - I get "Could Not Find Java SE Runtime Environment" or b) Find any reference to Java from the command line when typing java -version - I get "Error opening registry key 'Registry/JavaSoft/Java Runtime Environment." Any ideas?

  • Configuring Cruise Control Net with sourcesafe - Unable to load array item 'executable'

    - by albert
    Hi all, I'm trying to create a continuous integration environment. To do so, I've used a guide that can be found at http://www.15seconds.com/issue/040621.htm. In this step by step, the goal is to create a CI with CCNet, NAnt, NUni, NDoc, FxCop and source safe. I've been able to create my build by using the command prompt (despite the the different versions issues). The problem has come with the configuration of ccnet.config I've made some changes because of the new versions, but I'm still getting errors when starting the CCNet server. Can anyone help me to fix this issue or point where to find a guide with this scenario? The error that I'm getting: Unable to instantiate CruiseControl projects from configuration document. Configuration document is likely missing Xml nodes required for properly populating CruiseControl configuration. Unable to load array item 'executable' - Cannot convert from type System.String to ThoughtWorks.CruiseControl.Core.ITask for object with value: "\DevTools\nant\bin\NAnt.exe" Xml: E:\DevTools\nant\bin\NAnt.exe My CCNet config file below: <cruisecontrol> <project name="BuildingSolution"> <webURL>http://localhost/ccnet</webURL> <modificationDelaySeconds>10</modificationDelaySeconds> <triggers> <intervaltrigger name="continuous" seconds="60" /> </triggers> <sourcecontrol type="vss" autoGetSource="true"> <ssdir>E:\VSS\</ssdir> <executable>C:\Program Files\Microsoft Visual SourceSafe\SS.EXE</executable> <project>$/CCNet/slnCCNet.root/slnCCNet</project> <username>Albert</username> <password></password> </sourcecontrol> <prebuild type="nant"> <executable>E:\DevTools\nant\bin\NAnt.exe</executable> <buildFile>E:\Builds\buildingsolution\WebForm.build</buildFile> <logger>NAnt.Core.XmlLogger</logger> <buildTimeoutSeconds>300</buildTimeoutSeconds> </prebuild> <tasks> <nant> <executable>E:\DevTools\nant\bin\nant.exe</executable> <nologo>true</nologo> <buildFile>E:\Builds\buildingsolution\WebForm.build</buildFile> <logger>NAnt.Core.XmlLogger</logger> <targetList> <target>build</target> </targetList> <buildTimeoutSeconds>6000</buildTimeoutSeconds> </nant> </tasks> <publishers> <merge> <files> <file>E:\Builds\buildingsolution\latest\*-results.xml</file> </files> </merge> <xmllogger /> </publishers> </project> </cruisecontrol> enter code here

  • Disable SMS Syncing on Outlook

    - by Bruno Brant
    I've paired up my Samsung phone with an Outlook Exchange inbox (probably Outlook 2010), and now I've got the outstanding SMS syncing feature. Only, of course, it sucks, since my inbox get's flooded with SMS's that I already have on my phone. After looking around the internet for quite a while for a option that would allow me to disable that kind of syncing, the only guide I got was designed for Windows Phone 6.x. I want desperately to disable it. Anyone has any clue of how? I can't really believe that MS has forgotten to include the option. I've already looked at this question (Filter rule for SMS / text messages in exchange active sync (SMS sync)), and while it might help me, that's not what I'm looking for.

  • VPN server to access Samba4

    - by VisionIncision
    On my network I have an Ubuntu 12.04 server running Samba4, my domain is fully configured and functional. Now, I would like to enable VPN access over the internet, and have another box to do so. I have been searching on the internet for guides and information etc, but have not been successful. I have however found this guide http://www.howtogeek.com/51237/setting-up-a-vpn-pptp-server-on-debian/ but was wondering if I could adapt it somehow to enable access to my DC services. EDIT: I would need to authenticate my VPN server with my DC, if that is possible of course. Any insight would be wonderful. Regards, Jack Hunt

  • Setting number of columns programmatically in TableLayout

    - by TiGer
    Hi, I have an XML layout which contains a TableLayout with an unknown number of TableRows... The number of Rows will be established durin runtime, what I do know though is that I want two columns... So I have a couple of questions regarding this : - is there a way to set the whole TableLayout to have 2 columns ? - is there a way programmatically to give an id to the (during runtime) created TableRows which will be placed within the TableLayout, so I can reference them later on from other parts of the software ?

  • RAID Array performance on an HP Proliant ML350 G5 Smart Array E200i

    - by Nate Pinchot
    We have a client who is complaining about performance of an application which utilizes an MS SQL database. They do not believe the performance issues are the fault of the application itself. The Smart Array E200i RAID controller has 128MB cache and we have the cache set to 75% read/25% write. The disk array set to enable write caching. Recently we ran a disk performance test using SQLIO based on this guide. We used a 10 GB file for the test found that the average sequential read rate was ~60 MB/sec (megabytes/sec) and the average random read rate was ~30 MB/sec. Are these numbers on par for what the server should be performing? Better than on par? Horrible? Amazing?

  • How do partitions help in optimizing the harddrive?

    - by Fasih Khatib
    I was recently reading a guide on Tom's Hardware about how to optimize the harddrive. They listed creating partitions as one of them. They said keeping the various files seperate is a good idea as it reduces the read/write cycles required. Now my querry is: what size partitions do i make for my 500gb harddrive. Its completely blank. I will be installing WIN7 in it. My usual strategy is to divide it into two equal partitions. Is it the optimum size?

  • development server?

    - by ajsie
    for a project there will be me and one more programmer to develop a web service. i wonder how the development environment should be like. cause we need central storage (documents, pictures, business materials etc), file version handling, lamp (testing the web service) etc. i have never set up an environment for this before and want to have suggestions from experienced people which tools to use for effective collaboration. what crossed my mind: seperate applications: - google wave (for communication forth and back, setting up guide lines, other information) - team viewer (desktop sharing) - skype (calling) vps (ubuntu server): - svn (version tracking) - ftp (central storage) - lamp (testing the web service) - ssh (managing the vps) is this an appropriate programming environment? and regarding the vps, is it best practice to use ONE vps for all tasks listed up there? all suggestions and feedbacks are welcome!

  • handling mouseover/mouseout events for dijit.TitlePane's titleNode

    - by Shailesh Kumar
    I have a lot of dijit.TitlePanes stacked up one after another. I wish to handle the onmouseover and onmouseout events for the tile part of the TitlePane. What is the correct way of doing this? Will something like : dojo.connect(titlePane.titleNode, 'onmouseover', function f() {}); work, where titlePane is a reference to some dijit.TitlePane object? Is there some declarative way of setting up such an event handler using "dojo/mehtod"?

  • PackageMaker metapackage with SIMBL 0.9.x?

    - by subw
    I'm trying to create an installer using Apple's PackageMaker.app. As part of the installation, I want to install SIMBL with the metapackage mechanism provided by PackageMaker. However, when I add the SIMBL .pkg file and try to build my own package, I get the warning "No payload could be found. The package will not be built." for the SIMBL package reference. The same worked for an older version of SIMBL (0.8.*).

  • Does mixing Quartz and OpenGL-ES cause big performance degrade??

    - by Eonil
    I have a plan to make a game using OpenGL for 3D world view, and CALayer(or UIView) for HUD UI. It's easy to imagine performance degrade from mixing them, but the document which mention this impact disappeared: http://developer.apple.com/iphone/library/technotes/tn2008/tn2230.html I cannot find the document on current version of SDK reference. And I got this document: http://gamesfromwithin.com/gdc-2010-the-best-of-both-worlds-using-uikit-with-opengl If you experienced about this, please let me know about performance impact on current SDK.
