• Iterating 'Active' View Controllers

  - by ISDi

  Ola Folks, In an iPhone application I am displaying different views by using the addSubView:SomeViewController.view method. I want to be able to, at the very least, log the view controllers that are in the view hierarchy that is being displayed. I would prefer to be able to get a handle to a specific view controller. I know how to iterate the views, I just do not see how to access the view controllers of those views. I am looking for something that will give me the type of access to the view controllers that UINavigationController::ViewControllers does. I thought I could get away with: for (UIViewController* oVC in [self.view subviews]) but this is not having the intended effect. If someone has a way of doing this, please share it with me. -isdi-

• Codeigniter deny access to directory of controllers with apache config

  - by MAZUMA

  I’d like to restrict access to a folder of controllers that are used for admin purposes only. I’ve tried a number of ways and not coming up with a solution. These controllers are behind password protection. But, I’d like to just remove it from view if someone happens to stumble upon the right directory. Can this be done? I’d rather not do it from htaccess. I have access to the apache config files, so I’d like to handle it there. Does it have anything to do with the way Codeigniter routes? Or, am I just way off? This what I’m using that doesn’t work <Directory /var/www/application/controllers/folder/> Order deny,allow Deny from all Allow from xxx.xxx.xxx.xxx </Directory>

• TFS2010 Build Controllers

  - by Kabir Rao

  As I know, In TFS2010, One Build Controller serves One Project Collection. And, ideally one build server should have One build controller into it. However, as per the link below- http://marknic.com/2010/05/14/MultipleTFS2010BuildControllersOnASingleBuildBox.aspx we can install mutiple build controller in a single build box. Can two or more build controller can run at a same time. Because the link suggests that, we need to switch between controllers .... Is it that, we can use one controller at a time.

• PKI Issuing CA on Domain Controllers

  - by dunxd

  I am setting up a PKI which will initially be used internally. As we may grow our use of this I have opted for a three tier hierarchy - Offline Root and Policy CAs (one Policy CA at the moment for internal use), and online issuing CAs. We had initially discussed using our Domain Controllers as the Issuing CAs rather than setting up dedicated ones. I am now starting to have doubts about whether it is a good idea to have our DCs do certificate issuing. We have less than 1000 users, so our DCs aren't hugely taxed. Does anyone have any suggestions for or against doing this? We are currently running Windows 2003 Active Directory, but will be upgrading to Windows 2008 in the coming year. I'm setting up Windows 2008 PKI.

• Multiple test Active Directory envirovments hand in hand with production domain controllers

  - by MadBoy

  What's the best approach of having multiple test environments next to production one? We have multiple programming teams that build solutions that use Active Directory very often. We have tried different approaches, starting with their own domain controllers (in same subnet), or additional OU's in our production AD that the team gets control over and can create/delete accounts within that one OU. We thought of possible 4 solutions: Setting up separate OU's in ou production env. Creating subdomains for our contoso.com domain like test.contoso.com, something.contoso.com and delegating control to the teams (would we need additional DC's or the two that we have already would be enough to hold this? Setting up additional test domain controler that has a trust to our main domain and all teams can use the test domain controler as they please. Setting up single domain controller for every team/project. We're taking in consideration amount of resources needed, security (for example having multiple domain controlers with multiple passwords may lead users to use simpler passwords) and overall best practices for this scenario.

• How to identify RAID (5 or 6) controllers that allow dynamic resize of the array

  - by David Pfeffer

  I'm building a server with a RAID5 array, based on a hardware controller. I want to be able to later add additional disks and have the array rebalance across all of the disks, enlarging the usable size. I also want to be able to later upgrade to bigger disks (one at a time, of course) and then expand the array to fill the entire drive. These features are available in Linux software raid (md). I've also heard they're available in some hardware controllers. Currently, I own the Adaptec RAID 3805 card and the 3ware 9650se card. I'd prefer to use the Adaptec if possible, but I can't find if either of these cards offer this feature. If they don't, are there other affordable (read as: sub-$600) RAID cards available that can accomplish this?

• Remote additional domain controllers

  - by user125248

  Is it possible to setup several additional domain controllers (ADC) at remote locations that are connected via medium bandwidth DSL (2-10 Mbit) WAN connections for a single domain (intranet.example.com)? And would it be a good idea? We have five sites and would like to have extremely high availability if any of the site were to lose their Internet connection. However each site is very small, and all are over a fairly small geographical area within the same region, so it would seem strange to have a PDC for each of the sites. If it were possible to have an ADC for each site, would the clients use the ADC or just use the PDC if it's available to them?

• Is there a way to extend controllers in sails.js

  - by alarner

  Often times I will want to perform some action on every page of my web application or make some method available to all of my controllers. In the past with object oriented MVC frameworks I would have all of my controllers extend a root controller, placing everything I wanted done on every page in the constructor of that root controller. How would I accomplish something similar with sails.js / javascript?

• Migrateing to Windows Server 2008 R2 Domain Controllers - a few Questions/Issues

  - by Chris

  Ok so here's our setup: We have 2 Windows2k3 Domain Controllers. I am trying to replace them with Windows 2008 R2. The Win2k3 servers are DC01 and DC02. The Windows2k8 servers are DC1 and DC2. I prepared the Windows Server 2003 Forest Schema for a Domain Controller That Runs Windows Server 2008 or Windows Server 2008 R2. Then with both of the new servers up as member servers I dcpromo'd DC1 using the advanced option and added it successfully to my exisiting domain. Roles are GC, DNS and Active Directory Domain Services.I transferred The PDC, RID pool manager and Infrastructure master FSMO to the new DC.(DC1) The Schema master and Domain naming master are still on the old DC (DC01). The first issue I'm encountering is when i dcpromo the second DC (DC2) and select "Replicate data over the network from and existing domain controller" I select the new DC to replicate from (DC1) I get the following error: "Failed to identify the requested replica partner (dc1.xxx.org) as a valid domain controller with a machine account for (DC2$). This is likely due to either the machine account not being replicated to this domain controller because of replication latency or the domain controller not advertising the Active Directory Domain Services. Please consider retrying the operation with \dc01.xxx.org as the replica partner. "The server is unwilling to process the request." Is this because the Schema master and Domain naming master roles are still on the old DC (DC01)? And if so, if I transfer Schema master and Domain naming master roles to DC1 what is the risk or breaking my AD? I'm a little paranoid because this process HAS to be transparent. ANY down time or interruption will result in me getting a verbal ass kicking from my I.T. Director. Both of the new servers DNS point the the old DNS servers (DC01 and DC02) not themselves by the way. Thanks in Advance -Chris

• Domain Controller DNS Best Practice/Practical Considerations for Domain Controllers in Child Domains

  - by joeqwerty

  I'm setting up several child domains in an existing Active Directory forest and I'm looking for some conventional wisdom/best practice guidance for configuring both DNS client settings on the child domain controllers and for the DNS zone replication scope. Assuming a single domain controller in each domain and assuming that each DC is also the DNS server for the domain (for simplicity's sake) should the child domain controller point to itself for DNS only or should it point to some combination (primary VS. secondary) of itself and the DNS server in the parent or root domain? If a parentchildgrandchild domain hierarchy exists (with a contiguous DNS namespace) how should DNS be configured on the grandchild DC? Regarding the DNS zone replication scope, if storing each domain's DNS zone on all DNS servers in the domain then I'm assuming a DNS delegation from the parent to the child needs to exist and that a forwarder from the child to the parent needs to exist. With a parentchildgrandchild domain hierarchy then does each child forward to the direct parent for the direct parent's zone or to the root zone? Does the delegation occur at the direct parent zone or from the root zone? If storing all DNS zones on all DNS servers in the forest does it make the above questions regarding the replication scope moot? Does the replication scope have some bearing on the DNS client settings on each DC?

• MVC: Nested Views, and Controllers (for a website)

  - by incrediman

  I'm doing a PHP website using the MVC pattern. I am not using a framework as the site is fairly simple and I feel that this will give me a good opportunity to learn about the pattern directly. I have a couple questions. Question 1: How should I organize my views? I'm thinking of having a Page view which will have the header and footer, and which will allow for a Content view to be nested between them. Question 2: If I have 5 Content pages, should I make 5 different views that can be used as the content that is nested within the Page view? Or, should I make them all extend an abstract view called AbstractContent? Question 3: What about controllers? I think there should be one main controller at least. But then where does the request go from there? To another controller? Or should I just call the Page view and leave it at that? I thought that controllers were supposed to handle input, possibly modify a model, and select a view. But what if one of the views nested within the view that a controller calls requires additional input to be parsed? Question 4: Are controllers allowed to pass parameters into the view? Or should the controller simply modify the model, which will then affect the view? Or is the model only for DB access and other such things?

• Importing MEF-Plugins into MVC Controllers

  - by Marks

  Hello. There are several examples of using MEF to plugin whole controller/view packages into a MVC application, but i didn't found one, using MEF to plugin funcional parts, used by other controllers. For example, think of a NewsService with a simple interface like interface INewsService { List<NewsItem> GetAllNews(); } That gets news wherever he wants, and returns them in a List of NewsItems. My page should load an exported INewsService and show the news on the page. But there is the problem. I cant just use [Import] in the controllers, as they are just created when they are needed. Edit: (Importing them to the main MVCApplication class doesn't work, becouse i cant access it from the controllers.) I think i found a way to access the main app via HttpContext.ApplicationInstance. But the Service object in this instance is null although it was created successfully in the Application_Start() method. Any idea why? So, how can i access the NewsService from within a controller? Thanks in advance, Marks

• Newbie question about controllers in ASP.Net MVC.

  - by Sergio Tapia

  I'm following a tutorial on creating the NerdDinner using ASP.Net MVC. However, I'm using Visual Studio 2010 Ultimate edition and there was only MVC2 to choose from. So I've following the tutorial so far, and everything is really clicking and being really well explained, until this little hitch. The guide is asking me to create new methods on a Controller file like so: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace NerdDinner.Controllers { public class DinnersController : Controller { public void Index(){ Response.Write("<h1>Coming Soon: Dinners</h1>"); } public void Details(int id) { Response.Write("<h1>Details DinnerID: " + id + "</h1>"); } } } However, when I created the Controllers file, Visual Studio created an Index method already, but it looks vastly different to what the tutorial shows. Maybe this is the new way to do things using MVC2? using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace NerdDinner.Controllers { public class DinnersController : Controller { // // GET: /Dinners/ public ActionResult Index() { return View(); } } } My question is, how can I reproduce the Details and Index method (they're in MVC) to the MVC2 way? Is this even relevant? Thank you!

• Multi-Role Domain Controllers for Small Offices (< 50 clients)

  - by kce

  Warning: I'm a Linux/*NIX admin so this is all new to me. I understand that it's not considered a good idea to have only a single domain controller, and that it is also probably a good idea for a domain controller to only do AD/DHCP/DNS (Here). We have two offices, location A with 30 users and location B with 10 users. Our two offices are separated by a WAN that is not particularly robust so I have be instructed that we need to have standalone services in each office. This means that according to "best practices" we will need to build a domain controller and a separate file server in each office. Again, I am not knowledgeable in the ways of Windows but this seems a little unnecessary for an organization of 40 users. People have commented that I could "get away with" running file services on the domain controller as long as the "load is light". That just seems to generate more questions than it answers. What constitutes light load? What are the potential consequences of mixing these roles? Ideally I would prefer to only have one physical machine at each location. The one in location A (the location with IT staff) can act as the primary domain controller and the one in the smaller office can act as the backup domain controller. If either domain controller fails we can still use the other one for authentication (albeit with some latency) and if the WAN connection fails each office still has access to their respective "local" domain controller. If the file services are ALSO run on each server (and synchronized with something like DFS), a similar arrangement in terms of redundancy can be had without having to purchase, build and install two additional separate servers. It's not that I'm adverse to that (well, any more adverse than I am to whole thing to begin with) but to my simple mind it just seems, well a bit overkill. I can definitely see the benefits of functional separation when we're talking larger organizations, but I need to consider the additional overhead too. None of this excludes having a DRP setup for the domain controller/s. I assume you can lose two domain controllers just as easily as one.

• moving raid 10 to another identical server both on Smart Array 6i controllers

  - by SalimQrdl

  I have dead HP DL 380G4 with RAID 1+0 with 1 logical volume from 4x72GB drives on built-in Smart Array 6i 128Mb BBWC. It was shut down properly. It seems it was usual death for Proliant with ILO led 2,3,8 lighting. I want to move array to another identical server with same raid firmware level. What is the best strategy?: I have RAID 1+0 on bay 0 bay 1 bay 2 bay 3 As I understand bay0+bay1 are in RAID 1 , bay2+bay3 are in RAID 1, and both RAID 1 pairs are in RAID 0. So should I : Clear RAID config on new server, insert bay 0, bay 2 and power-on or Create RAID 1+0 with 1 logical volume from clear HDDs , and then poweroff ,remove HDDs and insert 2 HDDs(bay 0, bay 2) from old RAID 1+0. then power-on. (each hdd has its raid position info stored but may be could work on same config) According to documentation for Smart Array 6i it could be possible to migrate. however one requirement point is unclear for me Before you move drives, the following conditions must be met: • The array is in its original configuration. " What is orginal and non-original config for RAID 1+0? Another point "If you want to move an array to another controller, you must also consider the following additional limitations: • All drives in the array must be moved at the same time." I want to move one hdd from each RAID 1 pair. to have mirrors untouched just in case. Do they mean to move all 4 simultaniously? Smart Array 6i User Guide: Moving Drives and Arrays You can move drives to other ID positionson the same array controller. You can also move a complete arrayfrom one controller to another, even if the controllers are on different servers. Before you move drives, the following conditions must be met: • If moving thedrives to a different server, the new server must have enough empty bays to accommodate all the drives simultaneously. • The move will not result in more than 14 physical drives per controller channel. • No controller will be configured with more than 32 logical volumes. • The array has no failed or missing drives. • The array is in its original configuration. • The controller is not reading from or writing to any of the spare drives in the array. • The controller is not running capacity expansion, capacity extension, or RAID or stripe size migration. • The controller is using the latestfirmware version (recommended). If you want to move an array to another controller, you must also consider the following additional limitations: • All drives in the array must be moved at the same time. • In most cases, a moved array (and the logical drives that it contains) can still undergo arraycapacity expansion, logical drive capacity extension, or migration of RAID level orstripe size. When all the conditions have been met: Back up all data before removing any drives or changing configuration. This step is requiredif you are moving data-containing drives from a controller that does not have a battery-backed cache. Power down the system. If you are moving an array from a controller that contains a RAID ADG logical volume to a controller that does not support RAID ADG: Move the drives. Power up the system. If a 1724 POST message is displayed, drive positions were changed successfully and the configuration was updated. If a 1785 (NotConfigured)POST message is displayed: a. Power down the system immediately to prevent data loss. b. Return the drives to their original locations. c. Restore the data from backup, if necessary. Check the new drive configuration byrunning ORCA or ACU ("Configuring an Array" on page 9).

• Asp net MVC controllers and widgets

  - by Josemalive

  Hi, I have some doubts about ASP.Net MVC, and i would like to ask few questions. If i understood well, a controller/action is selected from a httprequest. As one request is used to get one web page, could we call to these controllers "page controllers"? My other question is about the widgets and RenderPartial method. If a widget represent a classic asp.net webcontrol or usercontrol, and i want to render this widget in a lot of pages, how could avoid repeat the logic of the widget if this logic is in the "page controller"? Any help would be appreciated. Thanks in advance. Best Regards. Jose

• Routing with command controller and sub controllers without using areas

  - by user205258

  How can I create a routing structure for a project management application where there are discrete controllers for all the relevant pieces such as TaskController, DocumentController etc and an Over arching controller. I would essentially like a structure like: http://server/Project/123/Task http://server/Project/123/Document I am using mvc1 so I have no access to areas etc. The project section will have a separate master page for project controllers such as task, document etc with a dfferent menu navigaton. I have tried three routes together n Global.asax like: routes.MapRoute( "Task", "Project/{id}/Task/{action}", new { controller = "Task", action = "Index", id = "" } ); routes.MapRoute( "Message", "Project/{id}/Message/{action}", new { controller = "Message", action = "Index", id = "" } ); routes.MapRoute( "Document", "Project/{id}/Document/{action}", new { controller = "Document", action = "Index", id = "" } ); What am I doing wrong here

• Fat ASP.NET MVC Controllers

  - by Mosh

  Hello, I have been reading about "Fat Controllers" but most of the articles out there focus on pulling the service/repository layer logic out of the controller. However, I have run into a different situation and am wondering if anyone has any ideas for improvement. I have a controller with too many actions and am wondering how I can break this down into many controllers with fewer actions. All these actions are responsible for inserting/updating/removing objects that all belong to the same aggregate. So I'm not quiet keen in having a seperate controller for each class that belongs to this aggregate... To give you more details, this controller is used in a tabbed page. Each tab represents a portion of the data for editing and all the domain model objects used here belong to the same aggregate. Any advice? Cheers, Mosh

• Data Formatters temporarily unavailable

  - by iphone newbie

  I'm currently working on an iPhone app. This app has a login screen, also a signup screen. After the user has successfully signed up, I dismiss the signup view, then the app automatically logs in using the created account. After which, the login view is dismissed, showing the main view. I'm trying to modify this by immediately dismissing the login view, since I already have the account details of the user when the signup is successful. Basically, the ideal flow is: after the user successfully signs up, I save the username and password in a singleton class, then dismiss the signup view. When I get to the parent view (which is the login screen), I have a variable that checks if there was a successful signup. If that variable is true, I want to immediately dismiss the login view. However, I come across this error message: Data Formatters temporarily unavailable, will re-try after a 'continue'. (Unknown error loading shared library "/Developer/usr/lib/libXcodeDebuggerSupport.dylib") I'm not really sure why this happens. I have no problems dismissing the login view when I go through the actual login procedure - which of course also dismisses the login view if the user inputs a correct username and password. I'm not exactly sure, but I'm starting to think that the iPhone cannot handle dismissing 2 view controllers almost at the same time. Is it possible that I'm dismissing the login view too quickly? Is that a factor? Is there anyway for me to be able to dismiss 2 view controllers almost simultaneously without coming across this error message?
