  • SQL Server 2008 table variable error: Must declare the scalar variable "@RESULT".

    - by Trindaz
    I'm using table values for the first time as a parameter to a function in SQL Server 2008. The code below produces this error: Must declare the scalar variable "@RESULT". Why?! I'm declaring it on the first line of the function! ALTER FUNCTION f_Get_Total_Amount_Due( @CUSTOMER_LIST [tpCSFM_CUSTOMER_SET_FOR_MONEY] READONLY ) RETURNS [tpCSFM_CUSTOMER_SET_FOR_MONEY] AS BEGIN --Prepare the return value, start with initial customer list DECLARE @RESULT AS [tpCSFM_CUSTOMER_SET_FOR_MONEY] INSERT INTO @RESULT SELECT * FROM @CUSTOMER_LIST --Todo: populate with real values UPDATE @RESULT SET tpCSAM_MONEY_VALUE = 100 --return total amounts as currency RETURN @RESULT END

  • WCF endpoint exception

    - by Lijo
    Hi Team, I am just trying with various WCF(in .Net 3.0) scenarios. I am using self hosting. I am getting an exception as "Service 'MyServiceLibrary.NameDecorator' has zero application (non-infrastructure) endpoints. This might be because no configuration file was found for your application, or because no service element matching the service name could be found in the configuration file, or because no endpoints were defined in the service element." I have a config file as follows (which has an endpoint) <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <services> <service name="Lijo.Samples.NameDecorator" behaviorConfiguration="WeatherServiceBehavior"> <host> <baseAddresses> <add baseAddress="http://localhost:8010/ServiceModelSamples/FreeServiceWorld"/> </baseAddresses> </host> <endpoint address="" binding="wsHttpBinding" contract="Lijo.Samples.IElementaryService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="WeatherServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="False"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration> And a Host as using System.ServiceModel; using System.ServiceModel.Dispatcher; using System.ServiceModel.Channels; using System.ServiceModel.Description; using System.Runtime.Serialization; namespace MySelfHostConsoleApp { class Program { static void Main(string[] args) { System.ServiceModel.ServiceHost myHost = new ServiceHost(typeof(MyServiceLibrary.NameDecorator)); myHost.Open(); Console.ReadLine(); } } } My Service is as follows using System.ServiceModel; using System.Runtime.Serialization; namespace MyServiceLibrary { [ServiceContract(Namespace = "http://Lijo.Samples")] public interface IElementaryService { [OperationContract] CompanyLogo GetLogo(); } public class NameDecorator : IElementaryService { public CompanyLogo GetLogo() { CircleType cirlce = new CircleType(); CompanyLogo logo = new CompanyLogo(cirlce); return logo; } } [DataContract] public abstract class IShape { public abstract string SelfExplain(); } [DataContract(Name = "Circle")] public class CircleType : IShape { public override string SelfExplain() { return "I am a Circle"; } } [DataContract(Name = "Triangle")] public class TriangleType : IShape { public override string SelfExplain() { return "I am a Triangle"; } } [DataContract] [KnownType(typeof(CircleType))] [KnownType(typeof(TriangleType))] public class CompanyLogo { private IShape m_shapeOfLogo; [DataMember] public IShape ShapeOfLogo { get { return m_shapeOfLogo; } set { m_shapeOfLogo = value; } } public CompanyLogo(IShape shape) { m_shapeOfLogo = shape; } } } Could you please help me to understand what I am missing here? Thanks Lijo

  • Exposing model object using bindings in custom NSCell of NSTableView

    - by Hooligancat
    I am struggling trying to perform what I would think would be a relatively common task. I have an NSTableView that is bound to it's array via an NSArrayController. The array controller has it's content set to an NSMutableArray that contains one or more NSObject instances of a model class. What I don't know how to do is expose the model inside the NSCell subclass in a way that is bindings friendly. For the purpose of illustration, we'll say that the object model is a person consisting of a first name, last name, age and gender. Thus the model would appear something like this: @interface PersonModel : NSObject { NSString * firstName; NSString * lastName; NSString * gender; int * age; } Obviously the appropriate setters, getters init etc for the class. In my controller class I define an NSTableView, NSMutableArray and an NSArrayController: @interface ControllerClass : NSObject { IBOutlet NSTableView * myTableView; NSMutableArray * myPersonArray; IBOutlet NSArrayController * myPersonArrayController; } Using Interface Builder I can easily bind the model to the appropriate columns: myPersonArray --> myPersonArrayController --> table column binding This works fine. So I remove the extra columns, leaving one column hidden that is bound to the NSArrayController (this creates and keeps the association between each row and the NSArrayController) so that I am down to one visible column in my NSTableView and one hidden column. I create an NSCell subclass and put the appropriate drawing method to create the cell. In my awakeFromNib I establish the custom NSCell subclass: PersonModel * aCustomCell = [[[PersonModel alloc] init] autorelease]; [[myTableView tableColumnWithIdentifier:@"customCellColumn"] setDataCell:aCustomCell]; This, too, works fine from a drawing perspective. I get my custom cell showing up in the column and it repeats for every managed object in my array controller. If I add an object or remove an object from the array controller the table updates accordingly. However... I was under the impression that my PersonModel object would be available from within my NSCell subclass. But I don't know how to get to it. I don't want to set each NSCell using setters and getters because then I'm breaking the whole model concept by storing data in the NSCell instead of referencing it from the array controller. And yes I do need to have a custom NSCell, so having multiple columns is not an option. Where to from here? In addition to the Google and StackOverflow search, I've done the obligatory walk through on Apple's docs and don't seem to have found the answer. I have found a lot of references that beat around the bush but nothing involving an NSArrayController. The controller makes life very easy when binding to other elements of the model entity (such as a master/detail scenario). I have also found a lot of references (although no answers) when using Core Data, but Im not using Core Data. As per the norm, I'm very grateful for any assistance that can be offered!

  • sql - datetime variable versus string representation of datetime variable

    - by BhejaFry
    Hi folks, I have a query that takes too long to respond when the search parameter happens to be a varchar datatype with date. However, if i convert varchar to datetime variable, the query runs fine. For ex: This takes too long. select count(id) from names where updateddate '1/5/2010' This runs fine. declare @dateparam datetime set @dateparam = convert(datetime, '1/5/2010',102) select count(id) from names where updateddate @dateparam What's the reason one runs fine but the other doesn't? TIA

    - by Mridang Agarwalla
    I need to display an image in a Django form. My Django form is quite simple - a single text input field. When I initialise my Django form in a view, I would like to pass the image path as a parameter, and the form when rendered in the template displays the image. Is is possible with Django forms or would i have to display the image separately? Thanks.

  • Drag and drop onto Python script in Windows Explorer

    - by grok
    I would like to drag and drop my data file onto a Python script and have it process the file and generate output. The Python script accepts the name of the data file as a command-line parameter, but Windows Explorer doesn't allow the script to be a drop target. Is there some kind of configuration that needs to be done somewhere for this work?

  • Final form of parametric SQL commands in ADO.NET

    - by mcoolbeth
    I am getting a syntax error when I send a parameterized query to Access from my C# program via ADO.NET. I, of course, know what SQL string I have included in my code, with the parameter names embedded inside. Does anyone know how I can look at the SQL string that is finally sent to the DBMS during after I call cmd.ExecuteNonQuery? Thanks.

  • How to find minimum of nonlinear, multivariate function using Newton's method (code not linear algeb

    - by Norman Ramsey
    I'm trying to do some parameter estimation and want to choose parameter estimates that minimize the square error in a predicted equation over about 30 variables. If the equation were linear, I would just compute the 30 partial derivatives, set them all to zero, and use a linear-equation solver. But unfortunately the equation is nonlinear and so are its derivatives. If the equation were over a single variable, I would just use Newton's method (also known as Newton-Raphson). The Web is rich in examples and code to implement Newton's method for functions of a single variable. Given that I have about 30 variables, how can I program a numeric solution to this problem using Newton's method? I have the equation in closed form and can compute the first and second derivatives, but I don't know quite how to proceed from there. I have found a large number of treatments on the web, but they quickly get into heavy matrix notation. I've found something moderately helpful on Wikipedia, but I'm having trouble translating it into code. Where I'm worried about breaking down is in the matrix algebra and matrix inversions. I can invert a matrix with a linear-equation solver but I'm worried about getting the right rows and columns, avoiding transposition errors, and so on. To be quite concrete: I want to work with tables mapping variables to their values. I can write a function of such a table that returns the square error given such a table as argument. I can also create functions that return a partial derivative with respect to any given variable. I have a reasonable starting estimate for the values in the table, so I'm not worried about convergence. I'm not sure how to write the loop that uses an estimate (table of value for each variable), the function, and a table of partial-derivative functions to produce a new estimate. That last is what I'd like help with. Any direct help or pointers to good sources will be warmly appreciated. Edit: Since I have the first and second derivatives in closed form, I would like to take advantage of them and avoid more slowly converging methods like simplex searches.

  • How to bind Apache to specific IP and port on Windows Server 2008

    - by webworm
    I have a Windows Server 2008 R2 that I use to host various ASP.NET applications under IIS7. I would also like to run various PHP based web apps using Apache (or Apache 2). The server has three static IP addresses assigned to it and I would like to bind one of the IP addresses to Apache while using the other two IP addresses for IIS. I can use the IIS Manager to bind the specific IP addresses to IIS, but I am unaware of how to do this with Apache. Can anyone tell me how to go about binding Apache to a specific IP address and port (port 80 is what I want to use). Please note .. I am aware that PHP can run under IIS. In fact that is how I have been running my PHP web applications. However, there are so many inconsistencies and pitfalls with PHP running under IIS that I just prefer to use Apache.

    I have a windows 7 machine 64 bit and IIS 7 I have a default website on the IIS.Its binding is {IP: All Unassigned , Port:80 , Host Name : blank} I have added a new asp.net application to that website,mapped physical path, have set the virtual path as "MyWebApp". Application pool for "MyWebApp" is "DefaultAppPool" {.Net Framework: 4.0 ; Managed Pipeline Mode: Classic} The problem I am facing is I can access the website using http://localhost, http://IP.IP.IP.IP and http://MyMachineName But I can not access the Application other than using http://localhost/MyWebApp What should I do if I want to access the webapp using http://MyMachineName/MyWebApp OR http://IP.IP.IP.IP/MyWebApp Please note : I have already created an inbound rule to allow all HTTP traffic for port 80 in firewall settings.

  • How to solve a deallocated connection in iPhone SDK 3.1.3? - Streams - CFSockets

    - by Christian
    Hi everyone, Debugging my implementation I found a memory leak issue. I know where is the issue, I tried to solve it but sadly without success. I will try to explain you, maybe someone of you can help with this. First I have two classes involved in the issue, the publish class (where publishing the service and socket configuration is done) and the connection (where the socket binding and the streams configuration is done). The main issue is in the connection via native socket. In the 'publish' class the "server" accepts a connection with a callback. The callback has the native-socket information. Then, a connection with native-socket information is created. Next, the socket binding and the streams configuration is done. When those actions are successful the instance of the connection is saved in a mutable array. Thus, the connection is established. static void AcceptCallback(CFSocketRef socket, CFSocketCallBackType type, CFDataRef address, const void *data, void *info) { Publish *rePoint = (Publish *)info; if ( type != kCFSocketAcceptCallBack) { return; } CFSocketNativeHandle nativeSocketHandle = *((CFSocketNativeHandle *)data); NSLog(@"The AcceptCallback was called, a connection request arrived to the server"); [rePoint handleNewNativeSocket:nativeSocketHandle]; } - (void)handleNewNativeSocket:(CFSocketNativeHandle)nativeSocketHandle{ Connection *connection = [[[Connection alloc] initWithNativeSocketHandle:nativeSocketHandle] autorelease]; // Create the connection if (connection == nil) { close(nativeSocketHandle); return; } NSLog(@"The connection from the server was created now try to connect"); if ( ! [connection connect]) { [connection close]; return; } [clients addObject:connection]; //save the connection trying to avoid the deallocation } The next step is receive the information from the client, thus a read-stream callback is triggered with the information of the established connection. But when the callback-handler tries to use this connection the error occurs, it says that such connection is deallocated. The issue here is that I don't know where/when the connection is deallocated and how to know it. I am using the debugger, but after some trials, I don't see more info. void myReadStreamCallBack (CFReadStreamRef stream, CFStreamEventType eventType, void *info) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; Connection *handlerEv = [[(Connection *)info retain] autorelease]; // The error -[Connection retain]: message sent to deallocated instance 0x1f5ef0 (Where 0x1f5ef0 is the reference to the established connection) [handlerEv readStreamHandleEvent:stream andEvent:eventType]; [pool drain]; } void myWriteStreamCallBack (CFWriteStreamRef stream, CFStreamEventType eventType, void *info){ NSAutoreleasePool *p = [[NSAutoreleasePool alloc] init]; Connection *handlerEv = [[(Connection *)info retain] autorelease]; //Sometimes the error also happens here, I tried without the pool, but it doesn't help neither. [handlerEv writeStreamHandleEvent:eventType]; [p drain]; } Something strange is that when I run the debugger(with breakpoints) everything goes well, the connection is not deallocated and the callbacks work fine and the server is able to receive the message. I will appreciate any hint!

  • How can I disable ipv6 on Ubuntu Server 8.04?

    - by Boden
    I'm trying to run Dell OMSA on Ubuntu 8.04. However, it's binding to ipv6 and not to an ipv4 address. I can't seem to figure out how to change this behavior. So, since I don't need ipv6 support, I'd like to just disable it and see if that clears things up. I've tried blacklisting ipv6 in /etc/modprobe.d/blacklist (blacklist ipv6), and turning it off in /etc/modprobe.d/aliases (alias net-pf-10 off). I'm seeing both solutions recommended in forums and blogs, but neither works.

  • Using embedded resources in Silverlight (4) - other cultures not being compiled

    - by Andrei Rinea
    I am having a bit of a hard time providing localized strings for the UI in a small Silverlight 4 application. Basically I've put a folder "Resources" and placed two resource files in it : Statuses.resx Statuses.ro.resx I do have an enum Statuses : public enum Statuses { None, Working } and a convertor : public class StatusToMessage : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (!Enum.IsDefined(typeof(Status), value)) { throw new ArgumentOutOfRangeException("value"); } var x = Statuses.None; return Statuses.ResourceManager.GetString(((Status)value).ToString(), Thread.CurrentThread.CurrentUICulture); } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } } in the view I have a textblock : <TextBlock Grid.Column="3" Text="{Binding Status, Converter={StaticResource StatusToMessage}}" /> Upon view rendering the converter is called but no matter what the Thread.CurrentThread.CurrentUICulture is set it always returns the default culture value. Upon further inspection I took apart the XAP resulted file, taken the resulted DLL file to Reflector and inspected the embedded resources. It only contains the default resource!! Going back to the two resource files I am now inspecting their properties : Build action : Embedded Resource Copy to output directory : Do not copy Custom tool : ResXFileCodeGenerator Custom tool namespace : [empty] Both resource (.resx) files have these settings. The .Designer.cs resulted files are as follows : Statuses.Designer.cs : //------------------------------------------------------------------------------ // <auto-generated> // This code was generated by a tool. // Runtime Version:4.0.30319.1 // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------ namespace SilverlightApplication5.Resources { using System; /// <summary> /// A strongly-typed resource class, for looking up localized strings, etc. /// </summary> // This class was auto-generated by the StronglyTypedResourceBuilder // class via a tool like ResGen or Visual Studio. // To add or remove a member, edit your .ResX file then rerun ResGen // with the /str option, or rebuild your VS project. [global::System.CodeDom.Compiler.GeneratedCodeAttribute("System.Resources.Tools.StronglyTypedResourceBuilder", "4.0.0.0")] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.Runtime.CompilerServices.CompilerGeneratedAttribute()] internal class Statuses { // ... yadda-yadda Statuses.ro.Designer.cs [empty] I've taken both files and put them in a console application and they behave as expected in it, not like in this silverlight application. What is wrong?
