  • Killing COM object from C#

    - by Pradeep
    I have a COM object that we are calling from C#. This works great, and I have my own pool of objects that I can use whenever I want. Now I need to kill the object. I've tried releasing the COM object explicitly and then garbage collecting from another thread, but that does nothing. Does anyone have any other ideas to kill this object? Thanks for the help. I've tried System.Runtime.InteropServices.Marshal.ReleaseComObject(myApp); GC.Collect(); GC.WaitForPendingFinalizers (); myApp = null; and I create it by myApplication.ApplicationClass myApp = new myApplication.ApplicationClass(); Thanks, Pradeep

  • Overwriting arguments object for a Javascript function

    - by Ian Storm Taylor
    If I have the following: // Clean input. $.each(arguments, function(index, value) { arguments[index] = value.replace(/[\W\s]+/g, '').toLowerCase(); }); Would that be a bad thing to do? I have no further use for the uncleaned arguments in the function, and it would be nice not to create a useless copy of arguments just to use them, but are there any negative effects to doing this? Ideally I would have done this, but I'm guessing this runs into problems since arguments isn't really an Array: arguments = $.map(arguments, function(value) { return value.replace(/[\W\s]+/g, '').toLowerCase(); }); Thanks for any input. EDIT: I've just realized that both of these are now inside their own functions, so the arguments object has changed. Any way to do this without creating an unnecessary variable?

  • g++ How to get warning on ignoring function return value

    - by ArunSaha
    lint produces some warning like: foo.c XXX Warning 534: Ignoring return value of function bar() From the lint manual 534 Ignoring return value of function 'Symbol' (compare with Location) A function that returns a value is called just for side effects as, for example, in a statement by itself or the left-hand side of a comma operator. Try: (void) function(); to call a function and ignore its return value. See also the fvr, fvo and fdr flags in §5.5 "Flag Options". I want to get this warning, if there exists any, during compilation. Is there any option in gcc/g++ to achieve this? I had turned on -Wall but that apparently did not detect this.

  • Immutability of big objects

    - by Malax
    Hi StackOverflow! I have some big (more than 3 fields) Objects which can and should be immutable. Every time I run into that case i tend to create constructor abominations with long parameter lists. It doesn't feel right, is hard to use and readability suffers. It is even worse if the fields are some sort of collection type like lists. A simple addSibling(S s) would ease the object creation so much but renders the object mutable. What do you guys use in such cases? I'm on Scala and Java, but i think the problem is language agnostic as long as the language is object oriented. Solutions I can think of: "Constructor abominations with long parameter lists" The Builder Pattern Thanks for your input!

  • Silverlight 3 DataBinding with ValueConverter: conditionally use the default value for property

    - by eriksmith200
    I have a DatePicker for which I want to set the BorderBrush to SolidColorBrush(Colors.Red) if the SelectedDate is null. If a date has been filled in though, I want to just have the default BorderBrush. I still want to be able to style the default BorderBrush in Blend, so I don't want to hardcode the default borderbrush of the DatePicker. So basically: xaml: <controls:DatePicker BorderBrush="{Binding SelectedDate, RelativeSource={RelativeSource Self}, Converter={StaticResource BrushConverter}, Mode=OneWay}"/> c#: public class BrushConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { return value == null ? new SolidColorBrush(Colors.Red) : /* when value != null have the bound property use it's default value */ } is this possible?

  • Generic unboxing of boxed value types

    - by slurmomatic
    I have a generic function that is constrained to struct. My inputs are boxed ("objects"). Is it possible to unbox the value at runtime to avoid having to check for each possible type and do the casts manually? See the above example: public struct MyStruct { public int Value; } public void Foo<T>(T test) where T : struct { // do stuff } public void TestFunc() { object o = new MyStruct() { Value = 100 }; // o is always a value type Foo(o); } In the example, I know that o must be a struct (however, it does not need to be MyStruct ...). Is there a way to call Foo without tons of boilerplate code to check for every possible struct type? Thank you.

  • c# send recive object over network?

    - by Data-Base
    Hello, I'm working on a server/client project the client will be asking the server for info and the server will send them back to the client the info may be string,number, array, list, arraylist or any other object I found allot of examples but I faced issues!!!! the solution I found so far is to serialize the object (data) and send it then de-serialize it to process here is the server code public void RunServer(string SrvIP,int SrvPort) { try { var ipAd = IPAddress.Parse(SrvIP); /* Initializes the Listener */ if (ipAd != null) { var myList = new TcpListener(ipAd, SrvPort); /* Start Listeneting at the specified port */ myList.Start(); Console.WriteLine("The server is running at port "+SrvPort+"..."); Console.WriteLine("The local End point is :" + myList.LocalEndpoint); Console.WriteLine("Waiting for a connection....."); while (true) { Socket s = myList.AcceptSocket(); Console.WriteLine("Connection accepted from " + s.RemoteEndPoint); var b = new byte[100]; int k = s.Receive(b); Console.WriteLine("Recieved..."); for (int i = 0; i < k; i++) Console.Write(Convert.ToChar(b[i])); string cmd = Encoding.ASCII.GetString(b); if (cmd.Contains("CLOSE-CONNECTION")) break; var asen = new ASCIIEncoding(); // sending text s.Send(asen.GetBytes("The string was received by the server.")); // the line bove to be modified to send serialized object? Console.WriteLine("\nSent Acknowledgement"); s.Close(); Console.ReadLine(); } /* clean up */ myList.Stop(); } } catch (Exception e) { Console.WriteLine("Error..... " + e.StackTrace); } } here is the client code that should return an object public object runClient(string SrvIP, int SrvPort) { object obj = null; try { var tcpclnt = new TcpClient(); Console.WriteLine("Connecting....."); tcpclnt.Connect(SrvIP, SrvPort); // use the ipaddress as in the server program Console.WriteLine("Connected"); Console.Write("Enter the string to be transmitted : "); var str = Console.ReadLine(); Stream stm = tcpclnt.GetStream(); var asen = new ASCIIEncoding(); if (str != null) { var ba = asen.GetBytes(str); Console.WriteLine("Transmitting....."); stm.Write(ba, 0, ba.Length); } var bb = new byte[2000]; var k = stm.Read(bb, 0, bb.Length); string data = null; for (var i = 0; i < k; i++) Console.Write(Convert.ToChar(bb[i])); //convert to object code ?????? Console.ReadLine(); tcpclnt.Close(); } catch (Exception e) { Console.WriteLine("Error..... " + e.StackTrace); } return obj; } I need to know a good serialize/serialize and how to integrate it into the solution above :-( I would be really thankful for any help cheers

  • window.setInterval from inside an object

    - by Keith Rousseau
    I'm currently having an issue where I have a javascript object that is trying to use setInterval to call a private function inside of itself. However, it can't find the object when I try to call it. I have a feeling that it's because window.setInterval is trying to call into the object from outside but doesn't have a reference to the object. FWIW - I can't get it to work with the function being public either. The basic requirement is that I may need to have multiple instances of this object to track multiple uploads that are occurring at once. If you have a better design than the current one or can get the current one working then I'm all ears. The following code is meant to continuously ping a web service to get the status of my file upload: var FileUploader = function(uploadKey) { var intervalId; var UpdateProgress = function() { $.get('someWebService', {}, function(json) { alert('success'); }); }; return { BeginTrackProgress: function() { intervalId = window.setInterval('UpdateProgress()', 1500); }, EndTrackProgress: function() { clearInterval(intervalId); } }; }; This is how it is being called: var fileUploader = new FileUploader('myFileKey'); fileUploader.BeginTrackProgress();

  • JAXB Web Services: Multiple Object Marshalling

    - by Luke Evans
    I can marshal and unmarshal 1 object with no problems (in netbeans); I need to know how to do this with multiple objects? I can't generate anything but null pointer exceptions when trying to unmarshal 3 objects into an array from XML; so I don't even know if I've marshalled the 3 out correctly. I know the basic idea of declaring the object, then using the jaxbu or jaxbm command, but I'd like to see this working for more than one object. **TLDR: How do I marshal/unmarshal multiple objects of a single class into/out of XML?? THANKS Code I have that marshals one object from XML: try { JAXBContext jc = JAXBContext.newInstance ("myOffers"); Unmarshaller u = jc.createUnmarshaller (); myOffers.Offer flight = (myOffers.Offer) u.unmarshal( new FileInputStream( "offers.xml" )); System.out.println ("Airline is : " + flight.getAirline()); System.out.println ("Origin is : " + flight.getOrigin()); System.out.println ("Destination is : " + flight.getDestination()); System.out.println ("Seats available : " + flight.getSeats()); System.out.println("Proximity to City Centre is : " + flight.getProximity()); System.out.println("Currency : " + flight.fare.getCurrency()); System.out.println("Value : " + flight.fare.getValue()); } catch (JAXBException e) { System.out.println("Error " + e);} ok so the Xml is: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns2:offer xmlns:ns2="http://simple.example.com/CInfoXmlDoc"> <Origin>Nottingham</Origin> <Destination>Istanbul</Destination> <Airline>Lufthansa</Airline> <Proximity>10</Proximity> <Seats>260</Seats> <Fare> <Currency>GBP</Currency> <Value>300</Value> </Fare> </ns2:offer> <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns2:offer xmlns:ns2="http://simple.example.com/CInfoXmlDoc"> <Origin>Birmingham</Origin> <Destination>Cairo</Destination> <Airline>Monarch</Airline> <Proximity>15</Proximity> <Seats>350</Seats> <Fare> <Currency>GBP</Currency> <Value>300</Value> </Fare> </ns2:offer> public static void main(String[] args) throws FileNotFoundException { int i = 0; int arraySize = 2; myOffers.Offer offer[] = new myOffers.Offer[arraySize]; offer[i] = new myOffers.Offer(); offer[i].fare = new myOffers.Offer.Fare(); offer[i].setAirline("Lufthansa"); offer[i].setOrigin("Nottingham"); offer[i].setDestination("Istanbul"); offer[i].setSeats(260); offer[i].setProximity(10); offer[i].fare.currency = "GBP"; offer[i].fare.value = 300; i++; offer[i] = new myOffers.Offer(); offer[i].fare = new myOffers.Offer.Fare(); offer[i].setAirline("Monarch"); offer[i].setOrigin("Birmingham"); offer[i].setDestination("Cairo"); offer[i].setSeats(350); offer[i].setProximity(15); offer[i].fare.currency = "GBP"; offer[i].fare.value = 300; try { int n = 0; FileOutputStream f = new FileOutputStream("offers.xml"); javax.xml.bind.JAXBContext jaxbCtx = javax.xml.bind.JAXBContext.newInstance(offer[n].getClass().getPackage().getName()); javax.xml.bind.Marshaller marshaller = jaxbCtx.createMarshaller(); marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_ENCODING, "UTF-8"); //NOI18N marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); while (n < arraySize) { marshaller.marshal(offer[n], f); n++; } } catch (javax.xml.bind.JAXBException ex) { // XXXTODO Handle exception java.util.logging.Logger.getLogger("global").log(java.util.logging.Level.SEVERE, null, ex); //NOI18N } } Which was generated by my marshal code found here: public static void main(String[] args) throws FileNotFoundException { int i = 0; int arraySize = 2; myOffers.Offer offer[] = new myOffers.Offer[arraySize]; offer[i] = new myOffers.Offer(); offer[i].fare = new myOffers.Offer.Fare(); offer[i].setAirline("Lufthansa"); offer[i].setOrigin("Nottingham"); offer[i].setDestination("Istanbul"); offer[i].setSeats(260); offer[i].setProximity(10); offer[i].fare.currency = "GBP"; offer[i].fare.value = 300; i++; offer[i] = new myOffers.Offer(); offer[i].fare = new myOffers.Offer.Fare(); offer[i].setAirline("Monarch"); offer[i].setOrigin("Birmingham"); offer[i].setDestination("Cairo"); offer[i].setSeats(350); offer[i].setProximity(15); offer[i].fare.currency = "GBP"; offer[i].fare.value = 300; try { int n = 0; FileOutputStream f = new FileOutputStream("offers.xml"); javax.xml.bind.JAXBContext jaxbCtx = javax.xml.bind.JAXBContext.newInstance(offer[n].getClass().getPackage().getName()); javax.xml.bind.Marshaller marshaller = jaxbCtx.createMarshaller(); marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_ENCODING, "UTF-8"); //NOI18N marshaller.setProperty(javax.xml.bind.Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); while (n < arraySize) { marshaller.marshal(offer[n], f); n++; } } catch (javax.xml.bind.JAXBException ex) { // XXXTODO Handle exception java.util.logging.Logger.getLogger("global").log(java.util.logging.Level.SEVERE, null, ex); //NOI18N } } Apologies, I'm fining this editor quite appalling but thats another matter.

  • Doctrine enum type by value

    - by MitMaro
    I have a column in a table defined as following in my yaml file: myTable: columns: value: type: enum length: 2 values: ['yes', 'no'] In the code I am trying to insert data into this table but I can't figure out a way to insert the data using the enum text value (ie. 'yes' or 'no'). What I was trying was is something like this: $obj = new myTable(); // the model for this table $obj->value = 'yes'; // if I use the numerical value for this it works I am using Doctrine 1.1.0.

  • jquery autocomplete on button click get hidden value

    - by gabriel
    using jquery autocomplete, we get hidden value by calling .result function like this $("#suggest").result(function(event, data, formatted) { $('#hidden').val(data[1]); }); This is only useful when we selected the option from autosuggest list and press enter. What i need is that i enter the option by typing the complete word without selecting it and clicking on Ok button? but i am always getting empty. <input type="text" id="suggest" /> <input type="button" value="Ok" onclick="GetValue()" /> <input type="hidden" id="hidden"/> function GetValue() { //get hidden field value - getting empty var hid=document.getElementById('hidden').value; }

  • Mandatory Parameters in Request object (WCF)

    - by Martin Moser
    lHi, I'm currently writing a WCF service. One of those methods get's a request object and returns a response object. In the request there are a couple of value-type members. Is there a way to define members are mandatory in the declarative way? I'm in an early stage of development and I don't want to start with versioning now. In addition I don't want to have method sig with 25 parameters, therefore I created the request object. The problem I have is that due to the value-types, I can never be sure if the consumer of the service intended to have the default value in there, or it was just by lazyness. On consumer side you don't easily detect that you probably missed that property. So I would like to have something that forces the caller of the service to provide an value, and if not he ideally get's a compile-time error. any ideas? tia, Martin

  • Python: Getting the attribute name that the created object will be given

    - by cool-RR
    Before I ask this, do note: I want this for debugging purposes. I know that this is going to be some bad black magic, but I want to use it just during debugging so I could identify my objects more easily. It's like this. I have some object from class A that creates a few B instances as attributes: class A(object): def __init__(self) self.vanilla_b = B() self.chocolate_b = B() class B(object): def __init__(self): # ... What I want is that in B.__init__, it will figure out the "vanilla_b" or whatever attribute name it was given, and then put that as the .name attribute to this specific B. Then in debugging when I see some B object floating around, I could know which one it is. Is there any way to do this?

  • ValidationProperty not returning entered value for textbox in custom ontrol

    - by nat
    hi I have a custom control, (relevant code at the bottom) it consists of some text/links and a hidden textbox (rather than a hidden input). when rendered, the user via another dialog and some JS sets the value of the textbox to an integer and clicks submit on the form. i am trying to assure that the user has entered a number (via the JS) and that the textbox is not still set to its default of "0" the requiredfieldvalidator works just fine, if i dont change the value it spots it on the client and fills the validation summary on the page with the appropriate message. unfortunately when i do fill the textbox, the validator also rejests the post as the controls textbox text value is still set to "0", even though on the form it has changed. clearly i am doing something wrong.. but cant work out what it is? could someone enlighten me please, this is driving me potty if i step through the code, when the get of the mediaidtext is hit,the findcontrol finds does not the textbox, if i inspect the controls collection however i can find the textbox, but its value is still "0" it also seems that when findcontrol is called, the createchildcontrols is called again - thus resetting the value back to "0" there.. ! how can i ever assure the control realises that the textbox value has changed? many thanks code below nat [ValidationProperty("MediaIdText")] public class MediaLibraryFileControl: CompositeControl { private int mediaId = 0; public int MediaId { get { return mediaId; } set { mediaId = value; } } public string MediaIdText { get { string txt = "0"; Control ctrl = this.FindControl(this.UniqueID+ "_hidden"); try { txt = ((TextBox)ctrl).Text; MediaId = Convert.ToInt32(txt); } catch { MediaId = 0; } return txt; } } protected override void CreateChildControls() { this.Controls.Add(new LiteralControl("<span>")); this.Controls.Add(new LiteralControl("<span id=\"" + TextControlName + "\">" + getMediaDetails() + "</span>")); TextBox tb = new TextBox(); tb.Text = this.MediaId.ToString(); tb.ID = this.UniqueID + "_hidden"; tb.CssClass = "hidden"; this.Controls.Add(tb); if (Select == true) { this.Controls.Add(new LiteralControl(string.Format("&nbsp;[<a href=\"javascript:{0}(this,'{1}','{2}')\" class=\"select\">{3}</a>]", dialog, this.UniqueID, this.categoryId, "select"))); this.Controls.Add(new LiteralControl(string.Format("&nbsp;[<a href=\"javascript:{0}(this,'{1}')\" class=\"select\">{2}</a>]", clearDialog, this.ID, "clear"))); } this.Controls.Add(new LiteralControl("</span>")); } protected virtual string getMediaDetails() { //... return String.Empty; } } this is the code adding the validationcontrol the editcontrol is the instance of the control above public override Control RenderValidationControl(Control editControl) { Control ctrl = new PlaceHolder(); RequiredFieldValidator req = new RequiredFieldValidator(); req.ID = editControl.ClientID + "_validator"; req.ControlToValidate = editControl.ID; req.Display = ValidatorDisplay.None; req.InitialValue = "0"; req.EnableClientScript = false; req.ErrorMessage = "control cannot be blank"; ctrl.Controls.Add(req); return ctrl; }
