  • ORB forwards to a wrong location

    - by dave-keiture
    I have an orbd started at a virtual host (with the IP A), with some remote object registered. Box that hosts virual boxes has IP B. When client tries to connect to the ORB at A to acquire the NamingContext, ORB replies with a LocationForward message poiniting to host B and port 1049 (like if another ORB would be started at that host). NamingContext is returned successfully, but obviously I'm not able to acqure the objects, registered at the NamingContext (at ORB hosted at A) by the name. Could anyone please explain what's happening? How can I access the orb hosted at A remotely? Thanks in advance.

  • C++ conversion operator between types in other libraries

    - by Dave
    For convenience, I'd like to be able to cast between two types defined in other libraries. (Specifically, QString from the Qt library and UnicodeString from the ICU library.) Right now, I have created utility functions in a project namespace: namespace MyProject { const icu_44::UnicodeString ToUnicodeString(const QString& value); const QString ToQString(const icu_44::UnicodeString& value); } That's all well and good, but I'm wondering if there's a more elegant way. Ideally, I'd like to be able to convert between them using a cast operator. I do, however, want to retain the explicit nature of the conversion. An implicit conversion should not be possible. Is there a more elegant way to achieve this without modifying the source code of the libraries? Some operator overload syntax, perhaps?

  • Asp.net MVC - Model binding image button

    - by big dave
    I've got a very complex form and i'm using the MVC model binding to capture all the information I've got it set up to capture all the different submissions that can happen as there are about 10 different submit buttons on the form, and there are also 2 image buttons I tried to get a bit clever (or so i thought) with capturing the image button submissions, and have created a child class so that i can capture the x value that's returned public class ImageButtonViewData { public int x { get; set; } public string Value { get; set; } } The parent class looks something like this public class ViewDataObject { public ImageButtonViewData ImageButton { get; set; } public ViewDataObject(){ this.ImageButton = new ImageButton(); } } The html for the image button then looks like <input type="image" id="ViewDataObject_ImageButton" name="ViewDataObject.ImageButton" /> This works fine in all browsers except for Chrome. When i debug it in chrome, the Request.Form object contains the values that i would expect, but after the model binding has occurred, the ImageButton property on the ViewDataObject has been set to null The only difference that i can see between the submission values is that Chrome passes the x as lower case (ViewDataObject.ImageButton.x) and IE passes it as upper case (ViewDataObject.ImageButton.X) but i didn't think that model binding took any notice of casing on property names Does anyone have any ideas ?

  • Python HTTPSConnection.close() does not appear to close the connection?

    - by Dave
    I'm not sure if this is a bug or if I'm just doing something wrong. If I were to do an HTTP connection like this: import httplib http_connection = httplib.HTTPConnection("192.168.192.196") http_connection.request("GET", "/") http_connection.sock.settimeout(20) response = http_connection.getresponse() data = response.read() http_connection.close() Then at a DOS prompt, I do this: netstat -ano | find /i "192.168.192.196:80" | find /i "ESTABLISHED" I get nothing. However, if I do the same thing, but change it to an HTTPSConnection: import httplib http_connection = httplib.HTTPSConnection("192.168.192.196") http_connection.request("GET", "/") http_connection.sock.settimeout(20) response = http_connection.getresponse() data = response.read() http_connection.close() Then do this: netstat -ano | find /i "192.168.192.196:443" | find /i "ESTABLISHED" I will actually see that the connection remains established until I actually ^Z out of the Python shell. This is happening in one of the applications I'm responsible for. Python isn't actually hanging there - it's simply leaving the connection open. Am I doing something wrong here? Do I need extra code to close the HTTPS connection? This is Python 2.6.4, btw.

  • Int - number too large. How to get program to fail?

    - by Dave
    Hi Problem: How do you get a program to fail if a number goes beyond the bounds of its type? This code below gives the wrong answer for sum of primes under 2 million as I'd used an int instead of a long. [TestMethod] public void CalculateTheSumOfPrimesBelow2million() { int result = PrimeTester.calculateTheSumOfPrimesBelow(2000000); // 2million Assert.AreEqual(1, result); // 1,179,908,154 .. this was what I got with an int... // correct answer was 142,913,828,922 with a long } public static class PrimeTester { public static int calculateTheSumOfPrimesBelow(int maxPrimeBelow) { // we know 2 is a prime number int sumOfPrimes = 2; int currentNumberBeingTested = 3; while (currentNumberBeingTested < maxPrimeBelow) { double squareRootOfNumberBeingTested = (double)Math.Sqrt(currentNumberBeingTested); bool isPrime = true; for (int i = 2; i <= squareRootOfNumberBeingTested; i++) { if (currentNumberBeingTested % i == 0) { isPrime = false; break; } } if (isPrime) sumOfPrimes += currentNumberBeingTested; currentNumberBeingTested += 2; // as we don't want to test even numbers } return sumOfPrimes; } }

  • How do I select an option using Spring's form:select tag?

    - by Dave
    I'm using Spring 3.1.1.RELEASE. Using the form:select tag, how do I specify which option should be selected? I want the first one to be selected, but when I put <form:select path="parentOrganization"> <form:option value="" label="Select an Org Type or Parent Org" /> <form:options items="${orgTypesWoParents}" itemValue="id" itemLabel="description" /> <form:option value="" label="=======================" /> </form:select> the last one is selected. I want to preserve the order of how everything is displayed, which is why I've arranged things in this way.

  • Icons in dired in Emacs (on Mac or Linux)

    - by Dave
    I'd like to have dired show a little icon next to each file, similar to what you'd see in "list" or "details" view on a graphical file browser. Someone posted a similar question but the only answer was for Windows only; I want to be able to do this on Linux or Mac.

  • How can I get the "Latency" of a process that has a TCP connection open?

    - by Dave
    Hello, I am looking to get the "Latency" field of a TCP connection. I notice windows Resource Monitor has this field, and I was wondering if there was a way I can find it. Preferrably without using WMI. If you are unsure what field I am talking about, open Task Manager, goto the Performance tab and hit the Resource Monitor button. Once Resource Monitor is open, expand the TCP Connections area and you will see a Latency field. Is there anyway to access this programatically? Thanks!

  • Consecutive calls/evaulations in a form?

    - by Dave
    Hey guys, simple question... Working with XLISP to write a program, but I've seemed to run into a simple fundamental problem that I can't seem to work around: perhaps someone has a quick fix. I'm trying to write an if statement who's then-clause evaluates multiple forms and returns the value of the last. In example: (setq POSITION 'DINING-ROOM) (defun LOOK (DIRECTION ROOM) ... ) (defun SETPOS (ROOM) ... ) (defun WHERE () ... ) (defun MOVE (DIRECTION) (if (not(equal nil (LOOK DIRECTION POSITION))) ; If there is a room in that direction ( ; Then-block: Go to that room. Return where you are. (SETPOS (LOOK DIRECTION ROOM)) (WHERE) ) ( ; Else-block: Return error (list 'CANT 'GO 'THERE) ) ) The logical equivalent intended is: function Move (Direction) { if(Look(Direction, Room) != null) { SetPos(Look(Direction,Room)); return Where(); } else { return "Can't go there"; } } (Apologies for the poor web-formatting.) The problem I have is with: ( (SETPOS (LOOK DIRECTION ROOM)) (WHERE) ) I simply want to return the evaluation of WHERE, but I need to execute the SETPOS function first. XLISP doesn't like the extra parentheses: if I remove the outer set, my WHERE list becomes my else (I don't want that). If I remove the sets around SETPOS and WHERE, it treats WHERE like an argument for SETPOS; I also don't want that. So, how do I simply evaluate the first, then the second and then return the values of the last evaluated?

  • Add/Edit Columns in DataBound DataGrid

    - by Dave
    I've got a datagrid that is databound from a database table. How do I: a) Edit the displayed value for a column using the values from other columns in the row? (For example, display a URL like: <a href="/url?param=columnA">columnB</a> where columnA is the value from column A and columnB is the value from columnB) b) Add an additional column using values from the other columns (similar to a.)

  • Put objects which are decorated with [DataContract] into a StateServer?

    - by Dave
    Is there anyway to stick objects which are decorated with DataContract attributes but not decorated with Serializable attributes in to a SqlServer StateServer? In other words, I would prefer not having to decorate these objects with the Serializable attribute as I will also have to implement IXmlSerizable on all of these objects because they do not have empty contstructors, and non-public setters for properties.

  • WPF control not being updated when source is changed

    - by Dave Colwell
    Hi, I have a ListBox which is bound to a list of objects. When the system initializes, the binding is done just fine, When i update the value in one of the fields on the ListBox, the item in the background updates as well, but when i update the value in the background it is not reflected in the ListBox. Does anyone know why this is?

  • Decimal type in Qt (C++)

    - by Dave
    What is the correct type to use in Qt development (or C++ in general) for decimal arithmetic, i.e. the equivalent of System.Decimal struct in .Net? Does Qt provide a built-in struct? (I can't find it in the docs, but maybe don't know where to look.) Is there a "standard" C++ library to use?

  • Stupid automatic assembly copy problem in Visual Studio 2008 - WTH am I doing wrong?

    - by Dave
    My lazier side has apparently gotten the best of me. When I started to develop with .NET under VS2008 recently, I was very happy to see that all of the dependencies automagically got copied to my application's bin/debug folder upon compilation. This is fantastic. I never even bothered to look into how / why this is done. Yesterday, I decided to make another plugin very similar to an existing one, so I literally copied the folder and all of project files, then renamed the folder and manually edited the project files and file references. I also changed the assembly's GUID. Everything builds fine, but this particular assembly is never copied into my application's bin/debug folder. It is marked as a dependency of my app as well. What did I miss here?

  • Multi dimensional array with get image data

    - by Dave
    I'm really confused with an array im making, its gotten a bit confusing to follow but i believe its the only way for me to approach what im trying to do. My idea here is to store getImageData in an array so i can link each image to an array of data. This is how i create my array: var listObj = { id: uid, extra: [ ctx2.getImageData(abposx,abposy,imgwidth,imgheight) ] }; pixeld.push(listObj); So now im trying to run through the array "pixeld" to find the uid but i don't know how the syntax should be.... this is what i tried: for (j = (pixeld.length-1); j > -1; --j){ if(pixeld[j].extra.data[3] !==0){ //line 220 matches.push(pixeld[j].id); } } The problem is i get this error: Uncaught TypeError: Cannot read property '3' of undefined on line 220 I have marked which line is 220 in the for loop. Any one know what my mistake is ?

  • How to resume an ftp download at any point? (shell script, wget option)?

    - by Dave
    hi! i want to download a huge file from an ftp server in chunks of 50-100MB each. At each point, i want to be able to set the "starting" point and the length of the chunk i want. i wont have the "previous" chunks saved locally (ie i cant ask the program to "resume" the downlaod). what is the best way of going about that? i use wget mostly, but would something else be better?

  • Qt/C++ regular expression library with unicode property support

    - by Dave
    I'm converting an application from the .Net framework to Qt using C++. The application makes extensive use of regular expression unicode properties, i.e. \p{L}, \p{M}, etc. I've just discovered that the QRegExp class lacks support for this among other things (lookbehinds, etc.) Can anyone recommend a C++ regular expression library that: Supports unicode properties Is unicode-aware in other respects (i.e. \w matches more than ASCII word characters) As a bonus, supports lookbehinds. Please don't point me to the wikipedia article; I don't trust it. That article says that QRegExp supports unicode properties. Unless I'm really doing something wrong, it doesn't. I'm looking for someone actually using unicode properties with a regex library in a project.

  • Why in the world is this Moq + NUnit test failing?

    - by Dave Falkner
    I have this dataAccess mock object and I'm trying to verify that one of its methods is being invoked, and that the argument passed into this method fulfills certain constraints. As best I can tell, this method is indeed being invoked, and with the constraints fulfilled. This line of the test throws a MockException: data.Verify(d => d.InsertInvoice(It.Is<Invoice>(i => i.TermPaymentAmount == 0m)), Times.Once()); However, removing the constraint and accepting any invoice passes the test: data.Verify(d => d.InsertInvoice(It.IsAny<Invoice>()), Times.Once()); I've created a test windows form that instantiates this test class, runs its .Setup() method, and then calls the method which I am wishing to test. I insert a breakpoint on the line of code where the mock object is failing the test data.InsertInvoice(invoice); to actually hover over the invoice, and I can confirm that its .TermPaymentAmount decimal property is indeed zero at the time the method is invoked. Out of desperation, I even added a call back to my dataAccess mock: data.Setup(d => d.InsertInvoice(It.IsAny<Invoice>())).Callback((Invoice inv) => System.Windows.Forms.MessageBox.Show(inv.TermPaymentAmount.ToString("G17"))); And this gives me a message box showing "0". This is really baffling me, and no one else in my shop has been able to figure this out. Any help would be appreciated. A barely related question, which I should probably ask independently, is whether it is preferable to use Mock.Verify(...) as I have here, or to use Mock.Expect(...).Verifiable followed by Mock.VerifyAll() as I have seen other people doing? If the answer is situational, which situations would warrent the use of one over the other?

  • How can I disable TinyMCE from stripping/modifying my HTML in Joomla?

    - by dave
    I've got a site running Joomla with TinyMCE set as the editor. One of the sites editors is now trying to embed a media player into an article but TinyMCE keeps messing up the HTML. I've tried setting the Extended Valid Elements, in the plugin config, to *[*] to allow anything and everything but it's not working. What I'd like is to disable the code stripping "feature" from TinyMCE all together. I don't want it trying to validate my HTML or anything like that. How can I disable the code stripping?

  • WCF operationcontract with List type unavailable in (Silverlight) client

    - by Dave
    This is the first time I have tried returning a List of data to a Silverlight client, so I'm having trouble getting the client to recognize this operationcontract. All others are fine. I have a method on the server called ReadOwFileData that needs to return a List. ReadOwFileDataCompletedEventArgs shows up in the Object Browser in the client, but not ReadOwFileDataAsync. What I want is similar to the tutorial here. The Dictionary collection type on the client is set to System.Collections.Generic.List. I tried deleting and recreating the service reference. Web.Config on the server is using basicHttpBinding. Here is the operationcontract on the server: [OperationContract] public List<OwFileData> ReadOwFileData(string OrderID) { DataClasses1DataContext db = new DataClasses1DataContext(); var dFileData = (from p in db.OwFileDatas where p.OrderID == OrderID select p).ToList(); List<OwFileData> x = new List<OwFileData>(dFileData); return x; } Incidently, this works fine: [OperationContract] public Customer GetShippingAndContactInfo(string login, string ordernum) { DataClasses1DataContext db = new DataClasses1DataContext(); Customer dInfo = (from p in db.Customers where p.Login == login select p).Single(); return dInfo; } I would like to read this data in the client and place it into an object I created called ObservableCollection. But that obviously can't happen until the client can see the method on the server. I do not know if this is an acceptable start, but this is what is on the client so far. The ReadOwFileDataAsync object is null: void populatefilesReceivedDataSource(string OrderID) { ArtUpload.ServiceReference1.UploadServiceClient client = new ArtUpload.ServiceReference1.UploadServiceClient(); var myList = client.ReadOwFileDataAsync(OrderID); // can I just itterate thru the list instead of 'binding' }
