• Transfer an account from a 'dead' domain

  - by PJC

  So - following from my previous question: How do I stop DFSR replication preventing a Domain Controller from advertising Domain Services?, I lost the FSMO DC, and my only other DC was in an unrecoverable state. I've created a new domain to continue my testing, but now have an issue which I suspect is relevant to any domain suffering a "catastrophe". I have user accounts and client PCs "on the old domain". (Actually 1 client PC and 3 accounts) I can still sign into the client PC as any of those users on the "dead" domain, because that is cached. There are (thankfully) no encrypted files in the "old" domain. What I would now like to do is migrate the full content (files, preferences, etc) from the "dead" domain to the new "live" domain for any/all user accounts, for the "old" PC. Is there anything out there which can assist me in doing so?

• Can I create a virtual network interface to connect to a real network device?

  - by michelemarcon

  I have a networked windows pc with 2 network interfaces. The first connects to a lan with ip address 10.1.. The second connects to another lan with ip address 10.2.. Maybe it's a dumb question, however is it possible to virtualize the second network interface, so that the pc can connect to the 2 lans? If necessary, I may switch to linux or paravirtualization. CLARIFICATION: I want to send DHCP broadcast packets on the second lan, but not on the first lan. I want to do it with one single physical network interface. At the moment, I'm not using any virtualization software.

• Finding Locked Out Users

  - by Bart Silverstrim

  Active Directory up to 2008 network (our servers are a mix of 2008, 2003...) I'm looking for a quick way to query AD to find out what users are locked out, preferably from a batch or script file, to monitor for possible issues with either user accounts being attacked by an automated attack or just anomalies in the network. I've Googled and my Google-fu has failed; I found a query off Microsoft's own knowledgebase that cites a string to use on Server 2003 with the management snap-in's saved queries (http://support.microsoft.com/kb/555131) but when I entered it, the query returned 400 users that a spot-check showed did NOT have a checkmark in the "Account is locked out" box under "account." In fact, I don't see anything wrong with their accounts. Is there a simple utility (wisesoft bulkadusers apparently uses this method behind the scenes, since it's results were also wrong) that will give a count of users and possibly their user object names? Script? Something?

• How do I set the TEMP environment variable for the "Network Service" user?

  - by Chris Phillips

  We have a system that uses Path.GetTempFile and Path.GetTempPath calls to work with temporary files fairly frequently. This system also runs as the "Network Service" user. We're finding that we're running out of room on the C drive (for other issues, our temp files are cleaned up correctly) and would like to be able to move the temp directory to a different drive. The easiest solution to this seems to be to change the TMP or TEMP environment variables for the Network Service user, but I only seem to be able to set my own user or the "system" variables that are overwritten by the Network Service user profile. How do I set these variables for the Network Service user?

• How can I avoid hard-coding YubiKey user identities into the PAM stack?

  - by CodeGnome

  The Yubico PAM Module seems to require changes to the PAM stack for each user that will be authenticated with a YubiKey. Specifically, it seems that each user's client identity must be added to the right PAM configuration file before the user can be authenticated. While it makes sense to add authorized keys to an authentication database such as /etc/yubikey_mappings or ~/.yubico/authorized_yubikeys, it seems like a bad practice to have to edit the PAM stack itself for each individual user. I would definitely like to avoid having to hard-code user identities into the PAM stack this way. So, is it possible to avoid hard-coding the id parameter to the pam_yubico.so module itself? If not, are there any other PAM modules that can leverage YubiKey authentication without hard-coding the stack?

• Linux Permissions

  - by Tres

  I am running Fedora 12 and I've setup a partition separate from my root partition to keep shared files and home directories. Now, I've been having permission issues where it says the user cannot chdir into their home directory (/files/home/*). Now, I fixed this originally by chmodding / to 0755 and the home directories also to 0755. And yes, the user is the owner:group of their home directory. Now get this, I didn't change a thing, rebooted, everything still works. Great, right? I boot the server up a day later, and now same ol issue. This is a home server that wasn't on at all at any point in between the working state and non-working state. Also, nothing else was modified. Any ideas? Thanks!

• Can't delete profile

  - by generic_noob

  Hi All, I have a client machine (XP SP3) which used to be connected to a windows 2003 domain, but the server has since gone down due to a hard drive failure, however the profiles still remain in 'documents and settings'. I have a local admin account on the same machine (in the administrator's group), except when i try to remove the profiles manually from System Properties - Advanced - User Profiles - Settings, the delete button is disabled. Also, Windows prevents me from deleting or renaming the user's profile folder as well, due to a lock with ntuser.dat Any thoughts on this would be greatly appreciated, Cheers!

• Stanford iPhone dev Paparazzi 1 setup help

  - by cksubs

  Hi, I'm having trouble using a tab bar control. Basically, when I build and run I'm just getting the blank white default "Window" screen. I was following this guide: http://www.iphoneosdevcafe.com/2010/03/assignment-4-part-1/#comment-36 Drag a Tab Bar Controller from the Library to MainWindow.xib. Control drag from the App Delegate to the Tab Bar Controller. Drag a Navigation Controller from the Library to MainWindow.xib. Control drag from the App Delegate to the Navigation Controller. Drag a second Navigation Controller from the Library to MainWindow.xib. Control drag from the App Delegate to the Navigation Controller. This completes all the connections between the App Delegate and the tab bar and two navigation controllers. By using IB to set up the tab bar and navigation controllers in this way, you need not allocate and init the controllers in AppDelegate.m. When you build and run this, you will see the tab bar controller and two navigation controllers. Is there a step there that he missed? How do I hook the Tab Bar Controller up to the Window? EDIT: Do I need to do something like this? mainTabBar = [[UITabBarController alloc] init]; [window addSubview:mainTabBar.view]; That's still not working, but I feel like I'm on the right track? Why can't this all be done from Interface Builder?

• Why is my app delegate's didFinishLaunchingWithOptions method all of sudden being called AFTER my Ro

  - by BeachRunnerJoe

  Hi. I've been playing with the iPad's SplitView template in Xcode. Here are two of the many important methods that are auto-generated for you by the Split View-based Application template... AppNameAppDelegate.m #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after app launch rootViewController.managedObjectContext = self.managedObjectContext; // Add the split view controller's view to the window and display. [window addSubview:splitViewController.view]; [window makeKeyAndVisible]; return YES; } RootViewController.m #pragma mark - #pragma mark View lifecycle - (void)viewDidLoad { [super viewDidLoad]; self.clearsSelectionOnViewWillAppear = NO; self.contentSizeForViewInPopover = CGSizeMake(320.0, 600.0); NSError *error = nil; if (![[self fetchedResultsController] performFetch:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } } When you build and run the project before making any changes at all, the application:didFinishLaunchingWithOptions method is called before the RootViewController:viewDidLoad method is called. I'm new to iPhone development, but I'm assuming this is the correct and typical sequence. However, as soon as I changed the RootViewController code and set it as a subclass of UIViewController (instead of UITableViewController by default), and made the respective adjustments in Interface Builder, suddenly the RootViewController:viewDidLoad is being called before the application:didFinishLaunchingWithOptions method. I need to get it back to the way it was working before because, as you can see in the code, the viewDidLoad method depends on didFinishLauchingWithOptions method to execute so it can set the rootViewController's managedObjectContext that it uses to perform the fetch request. Any ideas what caused this? Any ideas how I can fix this? Thanks so much in advance for your help! I'm gonna keep researching and playing with the code.

• svcutil, WSDL, and the generated interfaces not being sufficient for implementation

  - by chtmd

  I have a WSDL file defining a service that I have to implement in WCF. I had read that I could generate the proxy using svcutil from the WSDL file, and that I could then use the generated interfaces to implement the service. Unfortunately, I can't quite seem to find a way to have the interfaces contain the correct attributes to expose the contracts. All operations have the "OperationContractAttribute" attribute, but it appears as though for the service to be exposed, I require the "OperationContract" for each one. Same thing with "ServiceContractAttribute" and "ServiceContract", and I imagine DataContract, but I haven't gotten that far. I could manually make these changes, but I would much prefer a technique where the existing code could be easily used, or better code could be generated for my uses. Is there some way that this can be done? Thanks. EDIT: Command used: svcutil ObjectManagerService.wsdl /n:*,Sample /o:ObjectManagerServiceProxy.cs /nologo Code sample: public interface ObjectManagerSyncPortType { // CODEGEN: Generating message contract since the operation createObject is neither RPC nor document wrapped. [System.ServiceModel.OperationContractAttribute(Action="http://www.sample.com/createObject", ReplyAction="*")] [System.ServiceModel.XmlSerializerFormatAttribute()] Sample.createObjectResponse1 createObject(Sample.createObjectRequest1 request); As best as I can tell/see the WSDL file is entirely self-contained and requires no additional XSD files.

• Can you add a UITableViewController's TableView to another View?

  - by Dan Harrelson

  I've inserted a UITableViewController and it's corresponding UITableView into a simple IB document. The goal is to include the UITableView inside of a parent UIWindow (or UIView) with other "stuff" (anything really) adorning the table. Here's what that might look like in Interface Builder. http://danharrelson.com/images/skitch/iphone-tableview-3-20090701-205535.png I've tried this numerous times and always get to the same place. Build a working subclass of UITableViewController filled with data Customize the UTableView and it's cells including tap targets Add the newly created UITableViewController into an IB document Drag the UITableView out of the UITableViewController and into the main UIView Wire up the UITableViewController to the UITableView Note: adding the UITableViewController in code results in the same problem When running the app in the iPhone emulator or on a device the table displays correctly, but crashes the first time you try and interact with it. A scroll, a tap, anything crashes the app. This seems to be a delegate problem, like the UITableView doesn't know how to communicate back to the UITableViewController, but I have no idea how to correct the problem. So far I have been able to get by by customizing the tableHeaderView to get layouts that suffice, but I'd really prefer to have the other technique work.

• Follow tab's url in jquery ui tabs

  - by Aakash Chakravarthy

  Hello, I have jquery tabs like <ul id="tabsList"> <li><a href="#tab-1">Name 1</a></li> <li><a href="#tab-2">Name 2</a></li> <li><a href="http://www.google.com/">Name 3</a></li> </ul> <div id="tab-1">content 1</div> <div id="tab-2">content 2</div> the first two tabs load the respective divs. But the third one should go to google.com, instead it does nothing. It just adds http://example.com/index.html#ui-tabs-[object Object] to the url. I am developing a wordpress plugin and the admin page needs a tab interface. I tested this in a local server and not working update: i don't want to load google.com inside the page. It should open the webpage in new tab/window like ordinary links do.

• Cocoa Core data: cannot save Created Items in NSTableview

  - by Paul Rostorp

  Hello, I'm am a beginner in mac os x development and am trying to get started with all this. Here is my problem : I've create a non-document based cocoa app using core data as storage. I've added an entity and attributes to the xdatamodel. In IB i've created an NSArrayController and linked it properly. I've created an nstableview binded to the nsarraycontroller. Next I added a button linked to nsarraycontroller with the " add: " method. When I try it out, I can add and edit the items in the table. Here comes the problem: Core data is supposed to save everything automatically, but to make sure i linked the "save" button in the menu to the appdelegate and to the " file's owner" , first responder, application... everything possible ( with both " save :" and " saveaction:" methods ). And still it doesn't save when clicking save: when I restart the cell created ( and renamed ) are gone. And also, I didn't even edit the source code yet; core data for such simple tasks is supposed to only need Interface builder. Please help me for this, I haven't found any threads resolving this problem. Thank you in advance.

• WPF HiercharchicalDataTemplate.DataType: How to react on interfaces?

  - by David Schmitt

  Problem I've got a collection of IThings and I'd like to create a HierarchicalDataTemplate for a TreeView. The straightforward DataType={x:Type local:IThing} of course doesn't work, probably because the WPF creators didn't want to handle the possible ambiguities. Since this should handle IThings from different sources at the same time, referencing the implementing class is out of question. Current solution For now I'm using a ViewModel which proxies IThing through a concrete implementation: public interface IThing { string SomeString { get; } ObservableCollection<IThing> SomeThings { get; } // many more stuff } public class IThingViewModel { public IThing Thing { get; } public IThingViewModel(IThing it) { this.Thing = it; } } <!-- is never applied --> <HierarchicalDataTemplate DataType="{x:Type local:IThing}"> <!-- is applied, but looks strange --> <HierarchicalDataTemplate DataType="{x:Type local:IThingViewModel}" ItemsSource="{Binding Thing.SomeThings}"> <TextBox Text="{Binding Thing.SomeString}"/> </HierarchicalDataTemplate> Question Is there a better (i.e. no proxy) way?

• iPhone UITableView stutters with custom cells. How can I get it to scroll smoothly?

  - by Charles S.

  I'm using a UITableView to display custom cells created with Interface Builder. The table scrolling isn't very smooth (it "stutters") which leaves me to believe cells aren't being reused. Is there something wrong with this code? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"TwitterCell"; TwitterCell *cell = (TwitterCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ //new cell NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"TwitterCell" owner:nil options:nil]; for(id currentObject in topLevelObjects) { if([currentObject isKindOfClass:[TwitterCell class]]) { cell = (TwitterCell *)currentObject; break; } } } if([self.tweets count] > 0) { cell.lblUser.text = [[self.tweets objectAtIndex:[indexPath row]] username]; cell.lblTime.text = [[self.tweets objectAtIndex:[indexPath row]] time]; [cell.txtText setText:[[self.tweets objectAtIndex:[indexPath row]] text]]; [[cell imgImage] setImage:[[self.tweets objectAtIndex:[indexPath row]] image]]; } else { cell.txtText.text = @"Loading..."; } cell.selectionStyle = UITableViewCellSelectionStyleNone; return cell; }

• Rewrite arrays using collections

  - by owca

  I have a task, which I was able to do with the use of simplest methods - arrays. Now I'd like to go further and redo it using some more complicated java features like collections, but I've never used anything more complicated than 2d matrix. What should I look at and how to start with it. Should Tower become a Collection ? And here's the task : We have two classes - Tower and Block. Towers are built from Blocks. Ande here's sample code for testing: Block k1=new Block("yellow",1,5,4); Block k2=new Block("blue",2,2,6); Block k3=new Block("green",3,4,2); Block k4=new Block("yellow",1,5,4); Tower tower=new Tower(); tower.add(k1,k2,k3); "Added 3 blocks." System.out.println(tower); "block: green, base: 4cm x 3cm, thicknes: 2 cm block: blue, base: 6cm x 2cm, thicknes: 2 cm block: yellow, base: 5cm x 4cm, thicknes: 1 cm" tower.add(k2); "Tower already contains this block." tower.add(k4); "Added 1 block." System.out.println(tower); "block: green, base: 4cm x 3cm, thicknes: 2 cm block: blue, base: 6cm x 2cm, thicknes: 2 cm block: yellow, base: 5cm x 4cm, thicknes: 1 cm block: yellow, base: 5cm x 4cm, thicknes: 1 cm" tower.delete(k1); "Deleted 1 block" tower.delete(k1); "Block not in tower" System.out.println(tower); "block: blue, base: 6cm x 2cm, thicknes: 2 cm block: yellow, base: 5cm x 4cm, thicknes: 1 cm block: yellow, base: 5cm x 4cm, thicknes: 1 cm" Let's say I will treat Tower as a collection of blocks. How to perform search for specific block among whole collection ? Or should I use other interface ?

• Java inheritance question

  - by Milos

  I have an abstract class Airplane, and two classes PassengerAirplane and CargoAirplane, which extend class Airplane. I also have an interface Measurable, and two classes that implement it - People and Containers. So, Airplane can do many things on its own, and there is a method which allows measurable things to be added to the airplane (called addAMeasurableThing). The only difference between PassengerAirplane/CargoAirplane and just an Airplane is that addAMeasurableThing should only accept People / Containers, and not any kind Measurable things. How do I implement this? I tried doing: Airplane class: public abstract Airplane addAMeasurableThing (Measurable m, int position); PassengerAirplane class: public Airplane addAMeasurableThing (Measurable m, int position) { if (m instanceof People)... CargoAirplane class: public Airplane addAMeasurableThing (Measurable m, int position) { if (m instanceof Containers)... But when I was debugging it, I've noticed that addAMeasurableThing in the CargoAirplane class never gets called, because both methods have the same signature. So how can the appropriate PassengerAirplane/CargoAirplane's addAMeasurableThing be called, depending on the type of Measurable thing that is being passed on? Thanks!

• commitAnimations is not resizing my UIImageView subview

  - by AaronG

  I have created a UIView as a subview and to that subview I have added a UIImageView as a subview. UIView *viewCreated; UIButton *buttonCreated; UIImageView *imageViewCreated; CGRect myFrame = CGRectMake(0, 0, 1024, 1024); viewCreated = [[UIView alloc] initWithFrame:myFrame]; [viewCreated setTag:intTag]; viewCreated.backgroundColor = [UIColor redColor]; [self.view addSubview:viewCreated]; [self randomize]; UIImage *d1Image = [UIImage imageNamed:[NSString stringWithFormat:@"image%d.png", randomNumber]]; imageViewCreated = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f,0.0f,1024.0f, 1024.0f)]; [imageViewCreated setImage:[UIImage imageNamed:[NSString stringWithFormat:@"image%d.png", randomNumber]]]; [viewCreated addSubview:imageViewCreated]; //[imageViewCreated release]; return [viewCreated autorelease]; But when this code executes only the first subview is animated and resized. The UiimageView moves 200 pixels to the left but does not get resized. NSLog(@"sender tag %i",[sender tag]); UIView *currentView = [self.view viewWithTag:[sender tag]]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.5]; currentView.frame = CGRectMake(-200, 0,40, 102); [UIView commitAnimations]; I am pretty sure am I not creating the subviews correctly programmatically, because when I do it in Interface Builder it works as expected. Do I have to do something specific to actually attach the behavior of the second subview to the first subview?

• Fluently setting C# properties and chaining methods

  - by John Feminella

  I'm using .NET 3.5. We have some complex third-party classes which are automatically generated and out of my control, but which we must work with for testing purposes. I see my team doing a lot of deeply-nested property getting/setting in our test code, and it's getting pretty cumbersome. To remedy the problem, I'd like to make a fluent interface for setting properties on the various objects in the hierarchical tree. There are a large number of properties and classes in this third-party library, and it would be too tedious to map everything manually. My initial thought was to just use object initializers. Red, Blue, and Green are properties, and Mix() is a method that sets a fourth property Color to the closest RGB-safe color with that mixed color. Paints must be homogenized with Stir() before they can be used. Bucket b = new Bucket() { Paint = new Paint() { Red = 0.4; Blue = 0.2; Green = 0.1; } }; That works to initialize the Paint, but I need to chain Mix() and other methods to it. Next attempt: Create<Bucket>(Create<Paint>() .SetRed(0.4) .SetBlue(0.2) .SetGreen(0.1) .Mix().Stir() ) But that doesn't scale well, because I'd have to define a method for each property I want to set, and there are hundreds of different properties in all the classes. Also, C# doesn't have a way to dynamically define methods prior to C# 4, so I don't think I can hook into things to do this automatically in some way. Third attempt: Create<Bucket>(Create<Paint>().Set(p => { p.Red = 0.4; p.Blue = 0.2; p.Green = 0.1; }).Mix().Stir() ) That doesn't look too bad, and seems like it'd be feasible. Is this an advisable approach? Is it possible to write a Set method that works this way? Or should I be pursuing an alternate strategy?

• NSSegmentedControl -selectedSegment always returns 0

  - by SphereCat1

  I have an NSSegmentedControl with two segments set to "Select None" mode in Interface Builder. No matter what I try, I can't get -selectedSegment to return anything but 0, even though segment 0 is even disabled by default and can't possibly be selected. Here's the relevant function that gets called when you click any segment on the control: -(IBAction)changeStep:(id)sender { [stepContainer setHidden:TRUE]; [(NSView *)[[wizard stepArray] objectAtIndex:(NSInteger)[wizard step]] removeFromSuperview]; switch ([[navigationButton cell] selectedSegment]) { case 0: [wizard setStep:(NSInteger *)[wizard step]-1]; break; case 1: [wizard setStep:(NSInteger *)[wizard step]+1]; break; default: break; } //[[navigationButton cell] setSelected:FALSE forSegment:[navigationButton selectedSegment]]; if ([wizard step] > 0) { [wizard setStep:0]; [navigationButton setEnabled:FALSE forSegment:0]; } NSLog(@"%d", [wizard step]); [stepContainer addSubview:(NSView *)[[wizard stepArray] objectAtIndex:(NSInteger)[wizard step]]]; [stepContainer setHidden:FALSE withFade:TRUE]; } I've also tried using -isSelectedForSegment, but it has the same result. Any help you can provide would be awesome, I have no idea what I'm doing wrong. Thanks! SphereCat1

• How to configure a NSPopupButton for displaying multiple values in a TableView?

  - by jekmac

  Hi there! I'm using two entities A and B with to-many-to-many relationship. Lets say I got an entity A with attribute aAttrib and a to-many relationship aRelat to another entity B with attribute bAttrib and a to-many relationship bRelat with entity A. Now I am building an interface with two tables one for entity A and another for entity B. The table for entity B has two columns one for bAttrib and one for the relationship aRelat. The aRelat-column should be a NSPopupButtonCell to display multiple aAttrib values. I'd like to set all the bindings in InterfaceBuilder in Table Column Bindings: -- I have two NSArrayController each for one entity: Object Controller Mode:Entity Array Controller Bindings: Parameters Managed Object Context bind to File's Owner -- One Table Cloumn with a PopUpButtonCell: TableCloumnBindings Content bind to Entity A with ControllerKey arrangedObjects; Content Values bind to Entity A with ModelKeyPath aAttrib Selected Object bind to Entity B with ModelKeyPath bRelat I know that this configuration doesn't allow multiple value setting. But I don't know how to do the right one. Getting the following message: HIToolbox: ignoring exception 'Unacceptable type of value for to-many relationship: property = "bRelat"; desired type = NSSet; given type = NSCFString; value = testValue.' that raised inside Carbon event dispatch... Does anyone have any idea?

• Is there a case for parameterising using Abstract classes rather than Interfaces?

  - by Chris

  I'm currently developing a component based API that is heavily stateful. The top level components implement around a dozen interfaces each. The stock top-level components therefore sit ontop of a stack of Abstract implementations which in turn contain multiple mixin implementations and implement multiple mixin interfaces. So far, so good (I hope). The problem is that the base functionality is extremely complex to implement (1,000s of lines in 5 layers of base classes) and therefore I do not wish for component writers to implement the interfaces themselves but rather to extend my base classes (where all the boiler plate code is already written). If the API therefore accepts interfaces rather than references to the Abstract implementation that I wish for component writers to extends, then I have a risk that the implementer will not perform the validation that is both required and assumed by other areas of code. Therefore, my question is, is it sometimes valid to paramerise API methods using an abstract implementation reference rather than a reference to the interface(s) that it implements? Do you have an example of a well-designed API that uses this technique or am I trying to talk myself into bad-practice?

• Entity Framework Decorator Pattern

  - by Anthony Compton

  In my line of business we have Products. These products can be modified by a user by adding Modifications to them. Modifications can do things such as alter the price and alter properties of the Product. This, to me, seems to fit the Decorator pattern perfectly. Now, envision a database in which Products exist in one table and Modifications exist in another table and the database is hooked up to my app through the Entity Framework. How would I go about getting the Product objects and the Modification objects to implement the same interface so that I could use them interchangeably? For instance, the kind of things I would like to be able to do: Given a Modification object, call .GetNumThings(), which would then return the number of things in the original object, plus or minus the number of things added by the modification. This question may be stemming from a pretty serious lack of exposure to the nitty-gritty of EF (all of my experience so far has been pretty straight-forward LOB Silverlight apps), and if that's the case, please feel free to tell me to RTFM. Thanks in advance!
