  • C#, sometimes I could flush down my boss the toilet [closed]

    - by msfanboy
    Hello all, I got a paper of instructions from my boss. One of the instructions is in this order: Extend the method GetProductIdBy with theShipmentDate Overload the method GetProductIdBy without theShipmentDate This is the Method I speak about: ...and theShipmentDate is a DateTime variable public IProduct GetProductIdBy(string productID) { ... return product; } You know what I did? this - public IProduct GetProductIdBy(string productID, DateTime theShipmentDate ) { ... return product; } You know what my boss said? The above is wrong! I asked him how can I overload a method without a parameter like theShipmentDate ??? That makes no sense, he said that reason in because of the subversion repository... what the fuck?? But he did not tell me whats really right I would have to find out for myself... he just didnt tell me and I am sick of asking him every crap if he cant express himself properly. How would you manage his instruction?

  • COMException in System.WIndows.Forms.dll with Interactive Brokers TWS API

    - by Lirik
    Hi, I've been trying to run the sample project provided with the tutorial at stockbotprogramming http://www.stockbotprogramming.com/sharpcibtutorial1.php , but I keep getting a COMException every time I run the application. I have the TWS Client running and the sample VB projects provided with the API are able to connect just fine, but when I try to use the C# sample provided by the tutorial then I get the following exception: An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in System.Windows.Forms.dll Th exception happens when I try to add the TWS ActiveX control: namespace CSharpTutorial1 { public partial class Form1 : Form { private AxTWSLib.AxTws tws; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { tws = new AxTWSLib.AxTws(); tws.BeginInit(); tws.Enabled = true; tws.Location = new System.Drawing.Point(32, 664); tws.Name = "tws"; Controls.Add(tws); // <-- EXCEPTION HERE! tws.EndInit(); tws.connect("127.0.0.1", 7496, 0); String msg = "Connected to TWS server version " + tws.serverVersion + "at " + tws.TwsConnectionTime; MessageBox.Show(msg); } } } Does anybody know what could be causing this exception? Any ideas on how to fix it?

  • Global Hotkey in Mono and Gtk#

    - by Zach Johnson
    I'm trying to get a global hotkey working in Linux using Mono. I found the signatures of XGrabKey and XUngrabKey, but I can't seem to get them working. Whenever I try to invoke XGrabKey, the application crashes with a SIGSEGV. This is what I have so far: using System; using Gtk; using System.Runtime.InteropServices; namespace GTKTest { class MainClass { const int GrabModeAsync = 1; public static void Main(string[] args) { Application.Init(); MainWindow win = new MainWindow(); win.Show(); // Crashes here XGrabKey( win.Display.Handle, (int)Gdk.Key.A, (uint)KeyMasks.ShiftMask, win.Handle, true, GrabModeAsync, GrabModeAsync); Application.Run(); XUngrabKey( win.Display.Handle, (int)Gdk.Key.A, (uint)KeyMasks.ShiftMask, win.Handle); } [DllImport("libX11")] internal static extern int XGrabKey( IntPtr display, int keycode, uint modifiers, IntPtr grab_window, bool owner_events, int pointer_mode, int keyboard_mode); [DllImport("libX11")] internal static extern int XUngrabKey( IntPtr display, int keycode, uint modifiers, IntPtr grab_window); } public enum KeyMasks { ShiftMask = (1 << 0), LockMask = (1 << 1), ControlMask = (1 << 2), Mod1Mask = (1 << 3), Mod2Mask = (1 << 4), Mod3Mask = (1 << 5), Mod4Mask = (1 << 6), Mod5Mask = (1 << 7) } } Does anyone have a working example of XGrabKey? Thanks!

  • How do I know if I have an unmanaged resource?

    - by Shiftbit
    I've read that unmanaged resource are considered file handles, streams, anything low level. Does MSDN or any other source explain how to recognize an unmanaged resource? I can't seem to find any examples on the net that show unmanaged code, all the examples just have comments that say unmanaged code here. Can someone perhaps provide a realworld example where I would handle an unmanaged resources in an IDispose interface? I provided the IDisposable interface for your convience. How do I identify an unmanaged resource? Thanks in advance! IDisposable Reference Public Class Sample : Implements IDisposable Private disposedValue As Boolean = False 'To detect redundant calls ' IDisposable Protected Overridable Sub Dispose(ByVal disposing As Boolean) If Not Me.disposedValue Then If disposing Then ' TODO: free other state (managed objects). End If ' TODO: free your own state (unmanaged objects). ' TODO: set large fields to null. End If Me.disposedValue = True End Sub ' This code added by Visual Basic to correctly implement the disposable pattern. Public Sub Dispose() Implements IDisposable.Dispose ' Do not change this code. Put cleanup code in Dispose(ByVal disposing As Boolean) above. Dispose(True) GC.SuppressFinalize(Me) End Sub End Class

    This is for a tic tac toe game. I need help making a check statement to see if all the controls' Texts are non-blank, and if they are, you have a draw (if someone had won the previous code would have discovered that).

  • OSMDroid simple example required

    - by Bex
    Hi! I am trying to create an app that uses offline maps and custom tiles. For this I have decided to use OSMDroid and have included the jar within my project. I will create my custom tiles using MOBAC. I have been directed to these examples: http://code.google.com/p/osmdroid/source/browse/#svn%2Ftrunk%2FOpenStreetMapViewer%2Fsrc%2Forg%2Fosmdroid%2Fsamples but I am struggling to follow them as I am new to both java and android. I have created a class file called test (which I have created following an example!): public class test extends Activity { /** Called when the activity is first created. */ protected static final String PROVIDER_NAME = LocationManager.GPS_PROVIDER; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); MapView map = (MapView) findViewById(R.id.map); map.setTileSource(TileSourceFactory.MAPQUESTOSM); map.setBuiltInZoomControls(true); map.setMultiTouchControls(true); map.getController().setZoom(16); map.getController().setCenter(new GeoPoint(30266000, -97739000)); } } with a layout file: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <org.osmdroid.views.MapView android:id="@+id/map" android:layout_width="fill_parent" android:layout_height="fill_parent" tilesource="MapquestOSM" android:layout_weight="1" /> </LinearLayout> When I run this I see no map, just an empty grid. I think this is due to my tilesource but I'm not sure what I need to change it to. Can anyone help? Bex

  • How do you unit test a LINQ expression using Moq and Machine.Specifications?

    - by Phil.Wheeler
    I'm struggling to get my head around how to accommodate a mocked repository's method that only accepts a Linq expression as its argument. Specifically, the repository has a First() method that looks like this: public T First(Expression<Func<T, bool>> expression) { return All().Where(expression).FirstOrDefault(); } The difficulty I'm encountering is with my MSpec tests, where I'm (probably incorrectly) trying to mock that call: public abstract class with_userprofile_repository { protected static Mock<IRepository<UserProfile>> repository; Establish context = () => { repository = new Mock<IRepository<UserProfile>>(); repository.Setup<UserProfile>(x => x.First(up => up.OpenID == @"http://testuser.myopenid.com")).Returns(GetDummyUser()); }; protected static UserProfile GetDummyUser() { UserProfile p = new UserProfile(); p.OpenID = @"http://testuser.myopenid.com"; p.FirstName = "Joe"; p.LastLogin = DateTime.Now.Date.AddDays(-7); p.LastName = "Bloggs"; p.Email = "[email protected]"; return p; } } I run into trouble because it's not enjoying the Linq expression: System.NotSupportedException: Expression up = (up.OpenID = "http://testuser.myopenid.com") is not supported. So how does one test these sorts of scenarios?

  • Problem retrieving multiple instances of the same asp.net session variable

    - by sw1sh
    I'm having problems with retrieving multiple instances of a session variable from an InProc session state. In the following code I persist a simple BusinessObject into a session variable on the Page_Load event. On the click of a button I try to retrieve the object back into 2 new declared instances of the same BusinessObject. All works great until I change one of the properties in the first instance, it changes the second instance as well. Is this normal behaviour? I would have thought as these were new instances they wouldn’t demonstrate static behaviour? Any ideas where I'm going wrong? Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack Then ' create a new instance of a business object and set a containg variable Dim BO As New BusinessObject BO.SomeVariable = "test" ' persist to inproc session Session("BO") = BO End If End Sub Protected Sub btnRetrieveSessionVariable_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnRetrieveSessionVariable.Click ' retrieve the session variable to a new instance of BusinessObject Dim BO1 As New BusinessObject If Not Session("BO") Is Nothing Then BO1 = Session("BO") ' retrieve the session variable to a new instance of BusinessObject Dim BO2 As New BusinessObject If Not Session("BO") Is Nothing Then BO2 = Session("BO") ' change the property value on the first instance BO1.SomeVariable = "test2" ' why has this changed on both instances?

  • How to exploit Diffie-hellman to perform a man in the middle attack

    - by jfisk
    Im doing a project where Alice and Bob send each other messages using the Diffie-Hellman key-exchange. What is throwing me for a loop is how to incorporate the certificate they are using in this so i can obtain their secret messages. From what I understand about MIM attakcs, the MIM acts as an imposter as seen on this diagram: Below are the details for my project. I understand that they both have g and p agreed upon before communicating, but how would I be able to implement this with they both having a certificate to verify their signatures? Alice prepares ?signA(NA, Bob), pkA, certA? where signA is the digital signature algorithm used by Alice, “Bob” is Bob’s name, pkA is the public-key of Alice which equals gx mod p encoded according to X.509 for a fixed g, p as specified in the Diffie-Hellman key- exchange and certA is the certificate of Alice that contains Alice’s public-key that verifies the signature; Finally, NA is a nonce (random string) that is 8 bytes long. Bob checks Alice's signature, and response with ?signB{NA,NB,Alice},pkB,certB?. Alice gets the message she checks her nonce NA and calculates the joint key based on pkA, pkB according to the Diffie-Hellman key exchange. Then Alice submits the message ?signA{NA,NB,Bob},EK(MA),certA? to Bob and Bobrespondswith?SignB{NA,NB,Alice},EK(MB),certB?. where MA and MB are their corresponding secret messages.

  • Cron Job on Ubuntu Hardy Executing But Not Deleting Files As Expected

    - by Patrick McKenzie
    I have a bit of a pickle here and wonder if anyone can give me some pointers: I have a cron job which executes for a particular user daily and is supposed to sweep files in a particular directory. Technically, it is two jobs. I've turned on cron.log to verify they're actually executing, and they are: May 24 11:03:01 AppNameGoesHere /USR/SBIN/CRON[11257]: (mongrel_AppNameGoesHere) CMD (rm -rf /var/www/apps/AppNameGoesHere/current/public/ {popular,index,purchasing,purchasing-alternate,support,about-us,guarantee,screenshots}.htm{,l}) May 24 11:04:01 AppNameGoesHere /USR/SBIN/CRON[11260]: (mongrel_AppNameGoesHere) CMD (rm -rf /var/www/apps/AppNameGoesHere/current/public/ {stats,popular,bcf,articles,expenses}) I have removed the actual usernames and formatted it so that it is less ugly on StackOverflow. Now, my question: Despite the fact that I can see these deletions executing and apparently succeeding in the log, if I go to the specified directory, the files are still there. I initially suspected permission hijinx were going on, but I've verified that I can delete the files manually by su-ing into the mongrel_AppNameGoesHere user and issuing individual rm commands or by copy/pasting the cron job to the command line. Anything that I don't manually zap stays unzapped despite days of that cron job executing successfully. Any suggestions on to what might be happening? I was previously using Dapper Drake with these cron jobs in the /etc/crontab file directly, and when I upgraded to Hardy I moved them to user-specific crontabs (via sudo crontab -e - u mongrel_AppNameGoesHere), which was the point where they appear to have stopped working.)

  • How to use Object.GetHashCode() on a type that overrides GetHashCode()

    - by Jimmy
    Hi, I have a class A that implements IEquatable<, using its fields (say, A.b and A.c) for implementing/overriding Equals() and overriding GetHashCode(), and everything works fine, 99% of the time. Class A is part of a hierarchy (class B, C) that all inherit from interface D; they can all be stored together in a dictionary Dictionary, thus it's convenient when they all carry their own default Equals()/GetHashCode(). However, while constructing A I sometime need to do some work to get the values for A.b and A.c; while that's happening, I want to store a reference to the instance that's being built. In that case, I don't want to use the default Equals()/GetHashCode() overrides provided by A. Thus, I was thinking of implementing a ReferenceEqualityComparer, that's meant to force the use of Object's Equals()/GetHashCode(): private class ReferenceEqualityComparer<T> : IEqualityComparer<T> { #region IEqualityComparer<T> Members public bool Equals(T x, T y) { return System.Object.ReferenceEquals(x, y); } public int GetHashCode(T obj) { // what goes here? I want to do something like System.Object.GetHashCode(obj); } #endregion } The question is, since A overrides Object.GetHashCode(), how can I (outside of A) call Object.GetHashCode() for an instance of A? One way of course would be for A to not implement IEquatable< and always supply an IEqualityComparer< to any dictionary that I create, but I'm hoping for a different answer. Thanks

  • OpenNETCF.Stopwatch -> only ticks changing, not Elapsed

    - by pithyless
    I've been trying to track down a bug I thought was thread-related, but I think instead there is an issue with the way I am using OpenNETCF's Stopwatch. I am using OpenNETCF.IoC in my application, but for the sake of simplicity I moved the following code directly into a view: public partial class WorkoutView : SmartPart { ... private Stopwatch stopwatch; public WorkoutView() { ... stopwatch = new Stopwatch(); stopwatch.Reset(); stopwatch.Start(); WorkoutDisplayTimer = new Timer(); WorkoutDisplayTimer.Interval = 500; WorkoutDisplayTimer.Tick += new EventHandler(WorkoutDisplayTimer_Tick); WorkoutDisplayTimer.Enabled = true; } void WorkoutDisplayTimer_Tick(object sender, EventArgs e) { ... stopwatch.Stop(); lbl.Text = stopwatch.ElapsedTicks.ToString() + "NOT WORKING: " + stopwatch.Elapsed.ToString(); stopwatch.Start(); } ... } Long story short, looking at stopwatch in the debugger, the only values that ever get updated are ElapsedTicks, mElapsed, mStartPerfCount. Everything else is always zero. Is this expected behavior? Do I need to call an additional method to have the stopwatch calculate the Elapsed struct? (Note: stopwatch.ElapsedMilliseconds is also zero)

  • Workflow Foundation (WF) -- Why does setting a DependencyProperty to a COM object using SetValue() t

    - by stakx
    Assume that I have a .NET Workflow Foundation (WF) SequenceActivity class with the following property: public IWorkspace Workspace { get; set; } // ^^^^^^^^^^ // important: this is a COM interface type! public static DependencyProperty WorkspaceProperty = DependencyProperty.Register( "Workspace", typeof(IWorkspace), typeof(FoobarActivity)); // <-- this activity class This activity executes some code that sets both of the above like this: this.Workspace = ...; // exact code not relevant; property set to a COM object SetValue(WorkspaceProperty, this.Workspace); The last line (which makes the call to SetValue) results in an ArgumentException for the second parameter (having the value of this.Workspace): Type […].IWorkspace of dependency property Workspace does not match the value's type System.__ComObject.                                           (translated from German, the English exception text might differ slightly) As soon as I register the dependency property with typeof(object) instead of typeof(IWorkspace) as the second parameter, the code executes just fine. However, that would result in the possibility to assign just about any value to the dependency property, and I do not want that. It seems to me that WF dependency properties don't work for COM interop objects.Does anyone have a solution to this?

    I need to write a junit test for a rather complex application which runs in a tomcat. I wrote a class which builds up my spring context. private static ApplicationContext springContext = null; springContext = new ClassPathXmlApplicationContext( new String[] {"beans"....}); In the application there is a call: public class myClass implements ServletContextAware { .... final String folder = servletContext.getRealPath("/example"); ... } which breaks everything, because the ServletContext is null. I have started to build a mock object: static ServletConfig servletConfigMock = createMock(ServletConfig.class); static ServletContext servletContextMock = createMock(ServletContext.class); @BeforeClass public static void setUpBeforeClass() throws Exception { expect(servletConfigMock.getServletContext()).andReturn(servletContextMock).anyTimes(); expect(servletContextMock.getRealPath("/example")).andReturn("...fulllpath").anyTimes(); replay(servletConfigMock); replay(servletContextMock); } Is there a simple methode to inject the ServletContext or to start the tomcat with a deployment descriptor at the runtime of the junit test? I am using: spring, maven, tomcat 6 and easymock for the mock objects.

  • php xpath problems

    - by Phill Pafford
    I'm doing a cURL POST and get the error response back, parse it into an array but having issues with xpath now. // XML <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <errors xmlns="http://host/project"> <error code="30" description="[] is not a valid email address."/> <error code="12" description="id[] does not exist."/> <error code="3" description="account[] does not exist."/> <error code="400" description="phone[] does not exist."/> </errors> // Function / Class class parseXML { protected $xml; public function __construct($xml) { if(is_file($xml)) { $this->xml = simplexml_load_file($xml); } else { $this->xml = simplexml_load_string($xml); } } public function getErrorMessage() { $in_arr = false; $el = $this->xml->xpath("//@errors"); $returned_errors = count($el); if($returned_errors > 0) { foreach($el as $element) { if(is_object($element) || is_array($element)) { foreach($element as $item) { $in_arr[] = $item; } } } } else { return $returned_errors; } return $in_arr; } } // Calling function // $errorMessage is holding the XML value in an array index // something like: $arr[3] = $xml; $errMsg = new parseXML($arr[3]); $errMsgArr = $errMsg->getErrorMessage(); What I would like is all the error code and description attribute values

  • adding only odd numbers

    - by Jessica M.
    So the question I'm trying to solve the user is supposed to enter any positive number. Then I'm trying to write a program that adds only the odd numbers up to the number the user enters and displays the total. So for example if the user enters 4 my program should add four odd numbers. 1 + 3 + 5 + 7 = 16. The only tools I have available are for statement, if, if/else if,while loop and println. I can only figure out how to print out the odd numbers. I know I want to create a variable named total to store the value of adding up all the odd numbers but I don't know how that fits into the program. import acm.program.*; public class AddingOddNumbers extends ConsoleProgram { public void run() { int n = readInt("enter a positive nunber: "); int total = 0; for (int i = 0; i < n; i++) { if (n == 1) { println(1); } else { println((i * 2) + 1); } } } }

  • resolving overloads in boost.python

    - by swarfrat
    I have a C++ class like this: class ConnectionBase { public: ConnectionBase(); template <class T> Publish(const T&); private: virtual void OnEvent(const Overload_a&) {} virtual void OnEvent(const Overload_b&) {} }; My templates & overloads are a known fixed set of types at compile time. The application code derives from ConnectionBase and overrides OnEvent for the events it cares about. I can do this because the set of types is known. OnEvent is private because the user never calls it, the class creates a thread that calls it as a callback. The C++ code works. I have wrapped this in boost.python, I can import it and publish from python. I want do create the equivalent of the following in python : class ConnectionDerived { public: ConnectionDerived(); private: virtual void OnEvent(const Overload_b&) { // application code } }; But ... since python isn't typed, and all the boost.python examples I've seen dealing with internals are on the C++ side, I'm a little puzzled as to how to do this. How do I override specific overloads?

  • Java 1.4 singleton containing a mutable field

    - by Philippe
    Hi, I'm working on a legacy Java 1.4 project, and I have a factory that instantiates a csv file parser as a singleton. In my csv file parser, however, I have a HashSet that will store objects created from each line of my CSV file. All that will be used by a web application, and users will be uploading CSV files, possibly concurrently. Now my question is : what is the best way to prevent my list of objects to be modified by 2 users ? So far, I'm doing the following : final class MyParser { private File csvFile = null; private static Set myObjects = Collections.synchronizedSet(new HashSet); public synchronized void setFile(File file) { this.csvFile = file; } public void parse() FileReader fr = null; try { fr = new FileReader(csvFile); synchronized(myObjects) { myObjects.clear(); while(...) { // foreach line of my CSV, create a "MyObject" myObjects.add(new MyObject(...)); } } } catch (Exception e) { //... } } } Should I leave the lock only on the myObjects Set, or should I declare the whole parse() method as synchronized ? Also, how should I synchronize - both - the setting of the csvFile and the parsing ? I feel like my actual design is broken because threads could modify the csv file several times while a possibly long parse process is running. I hope I'm being clear enough, because myself am a bit confused on those multi-synchronization issues. Thanks ;-)

  • Populating JavaScript Array from JSP List

    - by tkeE2036
    Ok so perhaps someone can help me with a problem I'm trying to solve. Essentially I have a JSP page which gets a list of Country objects (from the method referenceData() from a Spring Portlet SimpleFormController, not entirely relevant but just mentioning in case it is). Each Country object has a Set of province objects and each province and country have a name field: public class Country { private String name; private Set<Province> provinces; //Getters and setters } public class Province { private String name; //Getters and setters } Now I have two drop down menus in my JSP for countries and provinces and I want to filter the provinces by country. I've been following this tutorial/guide to make a chain select in JavaScript. Now I need a dynamic way to create the JavaScript array from my content. And before anyone mentions AJAX this is out of the question since our project uses portlets and we'd like to stay away from using frameworks like DWR or creating a servlet. Here is the JavaScript/JSP I have so far but it is not populating the Array with anything: var countries = new Array(); <c:forEach items="${countryList}" var="country" varStatus="status"> countries[status.index] = new Array(); countries[status.index]['country'] = ${country.name}; countries[status.index]['provinces'] = [ <c:forEach items="${country.provinces}" var="province" varStatus="provinceStatus"> '${province.name}' <c:if test="${!provinceStatus.last}"> , </c:if> </c:forEach> ]; </c:forEach> Does anyone know how to create an JavaScript array in JSP in the case above or what the 'best-practice' would be considered in this case? Thanks in advance!
