  • [PowerShell] Sql Server SMO connection timeout not working

    - by Uros Calakovic
    I have the following PowerShell code: function Get-SmoConnection { param ([string] $serverName = "", [int] $connectionTimeout = 0) if($serverName.Length -eq 0) { $serverConnection = New-Object ` Microsoft.SqlServer.Management.Common.ServerConnection } else { $serverConnection = New-Object ` Microsoft.SqlServer.Management.Common.ServerConnection($serverName) } if($connectionTimeout -ne 0) { $serverConnection.ConnectTimeout = $connectionTimeout } try { $serverConnection.Connect() $serverConnection } catch [system.Management.Automation.MethodInvocationException] { $null } } $connection = get-smoconnection "ServerName" 2 if($connection -ne $null) { Write-Host $connection.ServerInstance Write-Host $connection.ConnectTimeout } else { Write-Host "Connection could not be established" } It seems to work, except for the part that attempts to set the SMO connection timeout. If the connection is successful, I can verify that ServerConnection.ConnectTimeout is set to 2 (seconds), but when I supply a bogus name for the SQL Server instance, it still attempts to connect to it for ~ 15 seconds (which is I believe the default timeout value). Does anyone have experience with setting SMO connection timeout? Thank you in advance.

  • Chaining IQueryables together

    - by Matt Greer
    I have a RIA Services based app that is using Entity Framework on the server side (possibly not relevant). In my real app, I can do something like this. EntityQuery<Status> query = statusContext.GetStatusesQuery().Where(s => s.Description.Contains("Foo")); Where statusContext is the client side subclass of DomainContext that RIA Services was kind enough to generate for me. The end result is an EntityQuery<Status> object who's Query property is an object that implements IQueryable and represents my where clause. The WebDomainClient is able to take this EntityQuery and not just give me back all of my Statuses but also filtered with my where clause. I am trying to implement this in a mock DomainClient. This MockDomainClient accepts an IQueryably<Entity> which it returns when asked for. But what if the user makes the query and includes the ad hoc additional query? How can I merge the two together? My MockDomainClient is (this is modeled after this blog post) ... public class MockDomainClient : LocalDomainClient { private IQueryable<Entity> _entities; public MockDomainClient(IQueryable<Entity> entities) { _entities = entities; } public override IQueryable<Entity> DoQuery(EntityQuery query) { if (query.Query == null) { return _entities; } // otherwise want the union of _entities and query.Query, query.Query is IQueryable // the below does not work and was a total shot in the dark: //return _entities.Union(query.Query.Cast<Entity>()); } } public abstract class LocalDomainClient : System.ServiceModel.DomainServices.Client.DomainClient { private SynchronizationContext _syncContext; protected LocalDomainClient() { _syncContext = SynchronizationContext.Current; } ... public abstract IQueryable<Entity> DoQuery(EntityQuery query); protected override IAsyncResult BeginQueryCore(EntityQuery query, AsyncCallback callback, object userState) { IQueryable<Entity> localQuery = DoQuery(query); LocalAsyncResult asyncResult = new LocalAsyncResult(callback, userState, localQuery); _syncContext.Post(o => (o as LocalAsyncResult).Complete(), asyncResult); return asyncResult; } ... }

  • Simulink: type consistency errors

    - by stanigator
    Using this Simulink model file as a reference, I'm trying to figure out the two following errors: I have no idea what has gone wrong with the data type consistency/conversion problems. Do you know what the error messages mean exactly in the context of a model? It would be great to get an interpretation of the problem to solve it. Thanks in advance.

  • How do you get credentials (NetworkCredential) of currently logged in user ?

    - by Ross
    Hi, I'm writing some code to utilise a 3rd party component, and I need to supply an object which implements ICredentials when I start to use it. If I write the following... var credential = new NetworkCredential("MyUsername", "MyPassword"); ...and pass "credential", it's fine. But I would like to pass the credentials of the current user (it's a Windows service, so runs as a specified user). I have tried both of the following, but neither appear to work (or return anything): NetworkCredential credential = System.Net.CredentialCache.DefaultCredentials; NetworkCredential credential = CredentialCache.DefaultNetworkCredentials; Can anyone suggest how to acquire an approriate object, which represents the credentials of the username that the service is running under ? Thanks, Ross

  • cannot evaluate expression because a native frame is on top of the call stack and system.accessviolationexception

  • NSObjectController confusion binding to a class property. Help!

    - by scottw
    Hi, I'm teaching myself cocoa and enjoying the experience most of the time. I have been struggling all day with a simple problem that google has let me down on. I have read the Cocoa Bindings Program Topics and think I grok it but still can't solve my issue. I have a very simple class called MTSong that has various properties. I have used @synthesize to create getter/setters and can use KVC to change properties. i.e in my app controller the following works: mySong = [[MTSong alloc]init]; [mySong setValue:@"2" forKey:@"version"]; In case I am doing something noddy in my class code MTSong.h is: #import <Foundation/Foundation.h> @interface MTSong : NSObject { NSNumber *version; NSString *name; } @property(readwrite, assign) NSNumber *version; @property(readwrite, assign) NSString *name; @end and MTSong.m is: #import "MTSong.h" @implementation MTSong - (id)init { [super init]; return self; } - (void)dealloc { [super dealloc]; } @synthesize version; @synthesize name; @end In Interface Builder I have a label (NSTextField) that I want to update whenever I use KVC to change the version of the song. I do the following: Drag NSObjectController object into the doc window and in the Inspector-Attributes I set: Mode: Class Class Name: MTSong Add a key called version and another called name Go to Inspector-Bindings-Controller Content Bind To: File's Owner (Not sure this is right...) Model Key Path: version Select the cell of the label and go to Inspector Bind to: Object Controller Controller Key: mySong Model Key Path: version I have attempted changing the Model Key Path in step 2 to "mySong" which makes more sense but the compiler complains. Any suggestions would be greatly appreciated. Scott Update Post Comments I wasn't exposing mySong property so have changed my AppController.h to be: #import <Cocoa/Cocoa.h> @class MTSong; @interface AppController : NSObject { IBOutlet NSButton *start; IBOutlet NSTextField *tf; MTSong *mySong; } -(IBAction)convertFile:(id)sender; @end I suspect File's owner was wrong as I am not using a document based application and I need to bind to the AppController, so step 2 is now: Go to Inspector-Bindings-Controller Content Bind To: App Controller Model Key Path: mySong I needed to change 3. to Select the cell of the label and go to Inspector Bind to: Object Controller Controller Key: selection Model Key Path: version All compiles and is playing nice!

    Hi, On Form Load I populate a menu with all possible colors so they user can pick a color. However when they pick a color the forecolor of my label is not changed.

  • Windows Server Appfabric

    - by yuben
    I am considering using Windows Server Appfabric for it caching functionality. I have an existing classic ASP application that I want to rewrite in ASP.NET MVC. However, I want to be able to do this "piecemeal" i.e. a few pages at a time. The problem is session state between the ASP and ASP.Net MVC application. I could use a database but I would like to use Appfabric since it has good scalabilty, admin, etc. My question is: does the Appfabric caching service/functionality have an API that I could wrap in .Net and expose to my classic ASP application as a com object? I could then change all the Session and Application caching in the classic application to use the com object i.e. Appfabric. In this way I can share session state between ASP.Net MVC and classic ASP. I will have to test the performance penalty associated with interop as well.

  • Heap Dump Root Classes

    - by Adnan Memon
    We have production system going into infinite loop of full gc and memory drops form 8 gigs to like 1 MB in just 2 minutes. After taking heap dump it tells me there an is an array of java.lang.Object ([Ljava.lang.Object) with millions of java.lang.String objects having same String taking 99% of heap. But it doesn't tell me which class is referencing to this array so that I can fix it in the code. I took the heap dump using jmap tool on JDK 6 and used JProfiler, NetBeans, SAP Memory Analyzer and IBM Memory Analyzer but none of those tell me what is causing this huge array of objects?? ... like what class is referencing to it or contains it. Do I have to take a different dump with different config in order to get that info? ... Or anything else that can help me find out the culprit class causing this ... it will help a lot.

  • What is the structure of a (Data Access) Service Class

    - by jiewmeng
    I learnt that I should be using service classes to persist entities into the database instead of putting such logic in models/controllers. I currently made my service class something like class Application_DAO_User { protected $user; public function __construct(User $user) { $this->user = $user } public function edit($name, ...) { $this->user->name = $name; ... $this->em->flush(); } } I wonder if this should be the structure of a service class? where a service object represents a entity/model? Or maybe I should pass a User object everytime I want to do a edit like public static function edit($user, $name) { $user->name = $name; $this->em->flush(); } I am using Doctrine 2 & Zend Framework, but it shouldn't matter

  • Using Moq at Blend design time

    - by adrian hara
    This might be a bit out there, but suppose I want to use Moq in a ViewModel to create some design time data, like so: public class SomeViewModel { public SomeViewModel(ISomeDependency dependency) { if (IsInDesignMode) { var mock = new Mock<ISomeDependency>(); dependency = mock.Object; // this throws! } } } The mock could be set up to do some stuff, but you get the idea. My problem is that at design-time in Blend, this code throws an InvalidCastException, with the message along the lines of "Unable to cast object of type 'Castle.Proxies.ISomeDependencyProxy2b3a8f3188284ff0b1129bdf3d50d3fc' to type 'ISomeDependency'." While this doesn't necessarily look to be Moq related but Castle related, I hope the Moq example helps ;) Any idea why that is? Thanks!

  • Python: Inheritance of a class attribute (list)

    - by Sano98
    Hi everyone, inheriting a class attribute from a super class and later changing the value for the subclass works fine: class Unit(object): value = 10 class Archer(Unit): pass print Unit.value print Archer.value Archer.value = 5 print Unit.value print Archer.value leads to the output: 10 10 10 5 which is just fine: Archer inherits the value from Unit, but when I change Archer's value, Unit's value remains untouched. Now, if the inherited value is a list, the shallow copy effect strikes and the value of the superclass is also affected: class Unit(object): listvalue = [10] class Archer(Unit): pass print Unit.listvalue print Archer.listvalue Archer.listvalue[0] = 5 print Unit.listvalue print Archer.listvalue Output: 10 10 5 5 Is there a way to "deep copy" a list when inheriting it from the super class? Many thanks Sano

  • Ho to stop scrolling in a Gallery Widget?

    - by Alexi
    I loaded some images into a gallery. Now I'm able to scroll but once started scrolling the scrolling won't stop.

  • UpdatePanel, Repeater, DataBinding Problem

    - by Gordon Carpenter-Thompson
    In a user control, I've got a Repeater inside of an UpdatePanel (which id displayed inside of a ModalPopupExtender. The Repeater is databound using an array list of MyDTO objects. There are two buttons for each Item in the list. Upon binding the ImageURL and CommandArgument are set. This code works fine the first time around but the CommandArgument is wrong thereafter. It seems like the display is updated correctly but the DTO isn't and the CommandArgument sent is the one that has just been removed. Can anybody spot any problems with the code?

  • ASP .NET: SQL Server Money Type and .NET Currency Type

    - by Rudi Ramey
    MS SQL Server's Money Data Type seems to accept a well formatted currency value with no problem (example: $52,334.50) From my research MS SQL Sever just ignores the "$" and "," characters. ASP .NET has a parameter object that has a Type/DbType property and Currency is an available option to set as a value. However, when I set the parameter Type or DbType to currency it will not accept a value like $52,334.50. I receive an error "Input string was not in a correct format." when I try to Update/Insert. If I don't include the "$" or "," characters it seems to work fine. Also, if I don't specify the Type or DbType for the parameter it seems to work fine also. Is this just standard behavior that the parameter object with its Type set to currency will still reject "$" and "," characters in ASP .NET? Here's an example of the parameter declaration (in the .aspx page): <asp:Parameter Name="ImplementCost" DbType="Currency" />

  • Sparse matrices / arrays in Java

    - by DanM
    I'm working on a project, written in Java, which requires that I build a very large 2-D sparse array. Very sparse, if that makes a difference. Anyway: the most crucial aspect for this application is efficency in terms of time (assume loads of memory, though not nearly so unlimited as to allow me to use a standard 2-D array -- the key range is in the billions in both dimensions). Out of the kajillion cells in the array, there will be several hundred thousand cells which contain an object. I need to be able to modify cell contents VERY quickly. Anyway: Does anyone know a particularly good library for this purpose? It would have to be Berkeley, LGPL or similar license (no GPL, as the product can't be entirely open-sourced). Or if there's just a very simple way to make a homebrew sparse array object, that'd be fine too. I'm considering MTJ, but haven't heard any opinions on its quality. Thanks!! -Dan

  • How to get SpecFlow working with xUnit.net as the test runner

    - by Mike Scott
    I'm trying to use xUnit.net as the test runner for SpecFlow. The SpecFlow 1.2 binaries from the official download area don't contain an xUnit.net provider but the master branch on GitHub has one, so I build SpecFlow.Core.dll from that. I'm using xUnit.net 1.5. However, when I change the unitTestProvider name in the app.config in my spec project, I get a null reference custom tool error and the generated .feature.cs file is the single line: Object reference not set to an instance of an object. Has anyone succeeded in getting SpecFlow to work with xUnit.net? If so, how?

  • UIViewController not loading a UIView

    - by Cosizzle
    Hey, I'm playing around with a script my teacher provided for a table based application. However I can't seem to get my own view to load. Files: SubViewOneController (which is a sub view, also has a nib) TapViewController (Custom UIView I created and want to add to a cell) RootViewController (Main controller which loads in the views) SimpleNavAppDelegate How it works: Within the RootViewController, there's an NSArray that holds NSDictionary objects which is declared in the -(void)awakeFromNib {} method - (void)awakeFromNib { // we'll keep track of our views controllers in this array views = [[NSMutableArray alloc] init]; // when using alloc you are responsible for it, and you will have to release it. // ==================================================================================================== // ==================================================================================================== // LOADING IN CUSTOM VIEW HERE: // allocate a set of views and add to our view array as a dictionary item TapViewController *tapBoardView = [[TapViewController alloc] init]; //push onto array [views addObject:[NSDictionary dictionaryWithObjectsAndKeys: @"Tab Gestures", @"title", tapBoardView, @"controller", nil]]; [tapBoardView release]; //release the memory // ==================================================================================================== // ==================================================================================================== SubViewOneController *subViewOneController = [[SubViewOneController alloc] init]; // This will set the 2nd level title subViewOneController.title = @"Swipe Gestures"; //set it's title //push it onto the array [views addObject:[NSDictionary dictionaryWithObjectsAndKeys: @"Swipe Gestures", @"title", subViewOneController, @"controller", nil]]; [subViewOneController release]; //release the memory } Later on I set the table view: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // OUTPUT -- see console NSLog(@"indexPath %i", indexPath.row); // OUTPUT: tapController: <TapViewController: 0x3b2b360> NSLog(@"view object: %@", [views objectAtIndex:indexPath.row]); // OUTPUT: view object: controller = <TapViewController: 0x3b0e290>; title = "Tab Gestures"; // ----- Hardcoding the controller and nib file in does work, so it's not a linkage issue ------ // UNCOMMENT TO SEE WORKING -- comment below section. //TapViewController *tapContoller = [[TapViewController alloc] initWithNibName:@"TapBoardView" bundle:nil]; //NSLog(@"tapController: %@", tapContoller); //[self.navigationController pushViewController:tapContoller animated:YES]; // ----- Random Tests ----- //UIViewController *targetViewController = [[views objectAtIndex: 0] objectForKey:@"controller"]; // DOES NOT WORK // LOADS THE SECOND CELL (SubViewOneController) however will not load (TapViewController) UIViewController *targetViewController = [[views objectAtIndex: indexPath.row] objectForKey:@"controller"]; NSLog(@"target: %@", targetViewController); // OUTPUT: target: <TapViewController: 0x3b0e290> [self.navigationController pushViewController:targetViewController animated:YES]; } Reading the comments you should be able to see that hardcoding the view in, works - however trying to load it from the View NSArray does not work. It does however contain the object in memory, seeing that NSLog proves that. Everything is linked up and working within the TapViewController nib file. So ya, im kinda stuck on this one, any help would be great! Thanks guys

  • Loading a Page into a jQuery Dialog

    - by Dave
    I tend to follow a fairly "modular" approach to building applications and I recently started working with jQuery. The application I'm working on is going to be fairly large so I'm trying to break pieces out into separate files/modules when possible. One example of this is a "User Settings" dialog. This dialog has a form, a few tabs, and quite a good number of input fields so I want to develop it in a separate HTML file (PHP actually, but it can be considered HTML for the purposes of this example). It's an entire page in and of itself with all the tags you would expect such as: <html><head></head><body></body></html> So I can now develop, what I want to be, the dialog separate from the base application. This dialog has it's own Javascript (A LOT of Javascript, in fact) in the head as well, with jQuery $(document).ready(){} capturing, etc. Everything works flawlessly in isolation. However, when I attempt to load the jQuery modal dialog with the page (inside of the main application page), as one might expect, trouble ensues. Here's a brief, very simple, example of what it looks like: editUserDialog.load ("editUser.php", {id : $('#userList').val(), popup : "true"}, function () { editUserDialog.dialog ("option", "title" , "Edit User"); editUserDialog.dialog ('open'); }); (I'm passing in a "popup" flag to the page so that the page can determine its context -- i.e. as a page or inside of the jQuery dialog). Question 1: When I moved the code from the "head" into "body" (in the editUser.php page) it actually worked for the most part. It seemed that jQuery was calling the $(document).ready() function in the context of the body of the loaded file and not the head. Is this a bad idea? Question 2: Is my process for building this application just totally flawed to begin with? I've scoured the net to attempt to find a "best practices" sort of document to building reasonably large applications using jQuery/PHP without a lot of success so maybe there's something out there someone else is aware of that I've somehow missed. Thanks for bearing with me while I attempt to describe the issues I've encountered and I hope I've accurately described the problem.

  • How to serialize and unserialize to/from a C# class?

    - by Earlz
    Hello, I have an object in Javascript that looks like this function MyObject(){ this.name=""; this.id=0; this..... } I then stringify an array of those objects and send it to an ASP.Net web service. Now what I want to do is do some processing on the JSON objects given to the webservice and return a JSON array of the same type of objects(same field names and such) How would I do this easily? I am using Netwonsoft.Json. Is there some way to turn a JSON string into a List or Array of an object?

  • Retrieve EF4 POCOs using WCF REST services starter kit

    - by muruge
    I am using WCF REST service (GET method) to retrieve my EF4 POCOs. The service seem to work just fine. When I query the uri in my browser I get the results as expected. In my client application I am trying to use WCF REST Starter Kit's HTTPExtension method - ReadAsDataContract() to convert the result back into my POCO. This works fine when the POCO's navigation property is a single object of related POCO. The problem is when the navigation property is a collection of related POCOs. The ReadAsDataContract() method throws an exception with message "Object reference not set to an instance of an object." Below are my POCOs. [DataContract(Namespace = "", Name = "Trip")] public class Trip { [DataMember(Order = 1)] public virtual int TripID { get; set; } [DataMember(Order = 2)] public virtual int RegionID { get; set; } [DataMember(Order = 3)] public virtual System.DateTime BookingDate { get; set; } [DataMember(Order = 4)] public virtual Region Region { // removed for brevity } } [DataContract(Namespace = "", Name = "Region")] public class Region { [DataMember(Order = 1)] public virtual int RegionID { get; set; } [DataMember(Order = 2)] public virtual string RegionCode { get; set; } [DataMember(Order = 3)] public virtual FixupCollection<Trip> Trips { // removed for brevity } } [CollectionDataContract(Namespace = "", Name = "{0}s", ItemName = "{0}")] [Serializable] public class FixupCollection<T> : ObservableCollection<T> { protected override void ClearItems() { new List<T>(this).ForEach(t => Remove(t)); } protected override void InsertItem(int index, T item) { if (!this.Contains(item)) { base.InsertItem(index, item); } } } And this is how I am trying retrieve a Region POCO. static void GetRegion() { string uri = "http://localhost:8080/TripService/Regions?id=1"; HttpClient client = new HttpClient(uri); using (HttpResponseMessage response = client.Get(uri)) { Region region; response.EnsureStatusIsSuccessful(); try { region = response.Content.ReadAsDataContract<Region>(); // this line throws exception because Region returns a collection of related trips Console.WriteLine(region.RegionName); } catch (Exception ex) { Console.WriteLine(ex.Message); } } } Would appreciate any pointers.

  • What does it take to prove this Contract.Requires?

    - by John Gietzen
    I have an application that runs through the rounds in a tournament, and I am getting a contract warning on this simplified code structure: public static void LoadState(IList<Object> stuff) { for(int i = 0; i < stuff.Count; i++) { // Contract.Assert(i < stuff.Count); // Contract.Assume(i < stuff.Count); Object thing = stuff[i]; Console.WriteLine(thing.ToString()); } } The warning is: contracts: requires unproven: index < @this.Count What am I doing wrong? How can I prove this on an IList<T>? Is this a bug in the static analyzer? How would I submit a bug report to Microsoft?
