  • Advice welcomed on creating my own Swing component

    - by Toto
    Recently I asked which was the best Swing component to bind to a BigDecimal variable (with some particular editing properties). It turns out that none of the standard Swing components suit me completely, nor did the third-party Swing component libraries I've found out there. So I’ve decided to create my own Swing component. Component description: I want to extend JTextField or JFormattedTextField, so my new component can be easily bound to a BigDecimal variable. The component will have customizable scale and length properties. Behavior: When the component is drawn, it shows only the decimal point and space for scale digits to its right. When the component receives focus the caret should be positioned left to the decimal point. As the user types numbers (any other character is ignored) they appear to the left of the caret, only length – scale numbers are accepted, any other number typed is ignored as the integer portion is full. Any time the user types the decimal point the caret moves to the right side of the decimal point. The following numbers typed are shown in the decimal part, only scale numbers are considered any other number typed is ignored as the decimal portion is full. Additionally, thousand separators should appear as the user types numbers left to the decimal point. Invoking a getValue() method on the component should yield the BigDecimal representing the number just entered. I’ve never created my own Swing component; I’ve barely used the standard ones. So I would appreciate any good tutorial/info/tip on creating the component described. This is the only thing I've got so far. Thanks in advance.

  • MySQL GROUP BY and JOIN

    - by christian
    Guys what's wrong with this SQL query: $sql = "SELECT res.Age, res.Gender, answer.*, $get_sum, SUM(CASE WHEN res.Gender='Male' THEN 1 else 0 END) AS males, SUM(CASE WHEN res.Gender='Female' THEN 1 else 0 END) AS females FROM Respondents AS res INNER JOIN Answers as answer ON answer.RespondentID=res.RespondentID INNER JOIN Questions as question ON answer.Answer=question.id WHERE answer.Question='Q1' GROUP BY res.Age ORDER BY res.Age ASC"; the $get_sum is an array of sql statement derived from another table: $sum[]= "SUM(CASE WHEN answer.Answer=".$db->f("id")." THEN 1 else 0 END) AS item".$db->f("id"); $get_sum = implode(', ', $sum); the query above return these values: Age: 20 item1 0 item2 1 item3 1 item4 1 item5 0 item6 0 Subtotal for Age 20 3 Age: 24 item1 2 item2 2 item3 2 item4 2 item5 1 item6 0 Subtotal for Age 24 9 It should return: Subtotal for Age 20 1 Subtotal for Age 24 2 In my sample data there are 3 respondents 2 are 24 yrs of age and the other one is 20 years old.

  • Marshalling polymorphic objects in JAX-WS

    - by pkchukiss
    I'm creating a JAX-WS type webservice, with operations that return an object WebServiceReply. The class WebServiceReply itself contains a field of type Object. The individual operations would populate that field with a few different data-types, depending on the operation. Publishing the WSDL (I'm using Netbeans 6.7), and getting a ASP.NET application to retrieve and parse the WSDL was fine, but when I tried to call an operation, I would receive the following exception: javax.xml.ws.WebServiceException: javax.xml.bind.MarshalException - with linked exception: [javax.xml.bind.JAXBException: class [LDataObject.Patient; nor any of its super class is known to this context.] How do I mark the annotations in the DataObject.Patient class, as well as the WebServiceReply class to get it to work? I haven't been able to fine a definitive resource on marshalling based upon annotations within the target classes either, so it would be great if anybody could point me to that too. WebServiceReply.java @XmlRootElement(name="WebServiceReply") public class WebServiceReply { private Object returnedObject; private String returnedType; private String message; private String errorMessage; .......... // Getters and setters follow } DataObject.Patient.java @XmlRootElement(name="Patient") public class Patient { private int uid; private Date versionDateTime; private String name; private String identityNumber; private List<Address> addressList; private List<ContactNumber> contactNumberList; private List<Appointment> appointmentList; private List<Case> caseList; } Solution (Thanks to Gregory Mostizky for his answer) I edited the WebServiceReply class so that all the possible return objects extend from a new class ReturnValueBase, and added the annotations using @XmlSeeAlso to ReturnValueBase. JAXB worked properly after that! Nonetheless, I'm still learning about JAXB marshalling in JAX-WS, so it would be great if anyone can still post any tutorial on this. Gregory: you might want to add-on to your answer that the return objects need to sub-class from ReturnValueBase. Thanks a lot for your help! I had been going bonkers over this problem for so long!

  • C#/MonoDevelop: GTK MessageDialogs require a doubleclick to close - why?

    - by Connel
    I'm a newbie programmer writting a program in MonoDevelop in C# and have a porblem with my gtk MessageDialogs. The close button on the window boarders of my GTK Message dialogues require a double click to actually close them. The close button on the dialogue its self works fine. Could someone please tell me how I can fix this below is the code: if (fchDestination.CurrentFolder == fchTarget.CurrentFolder) { MessageDialog msdSame = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "Destination directory cannot be the same as the target directory"); msdSame.Title="Error"; if ((ResponseType) msdSame.Run() == ResponseType.Close) { msdSame.Destroy(); } return; } if (fchTarget.CurrentFolder.StartsWith(fchDestination.CurrentFolder)) { MessageDialog msdContains = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "error"); msdContains.Title="Error"; if ((ResponseType) msdContains.Run() == ResponseType.Close) { msdContains.Destroy(); } return; }

  • Regex Problem in PHP

    - by Chris
    I'm attempting to utilize the following Regex pattern: $regex = '/Name: [a-zA-Z ]*] [0-9]/'; When testing it in Rubular, it works fine, but when using PHP the expression never returns true, even when it should. Incidentally, if I remove the "[0-9]" part, it works fine. Is there some difference in PHP's regex syntax that I'm overlooking? Edit: I'm looking for the characters "Name:" then a name containing any number of letters or spaces, then a "]", then a space, then a single number. So "Name: Chris] 5" would return true and "Name: Chris] [lorem ipsum]" should return false. I also tried escaping the second bracket "\[" but this did not fix the problem.

  • How can I stub out a call to super in a imported Java class in JRuby for testing

    - by Doug Chew
    I am testing Java classes with RSpec and JRuby. How can I stub out a call to super in an imported Java class in my RSpec test? For example: I have 2 Java classes: public class A{ public String foo() { return "bar"; } } public class B extends A public String foo() { // B code return super.foo(); } } I am just trying to test the code in B.foo and not the code in A.foo with JRuby. How can I stub out the call to the super class method in my RSpec test? rspec test: java_import Java::B describe B do it "should not call A.foo" do # some code to stub out A.foo b = B.new b.foo.should_not == "bar" end end I have tried including a module with a new foo method in B's class hoping that it would hit the module method first but B still makes a call to A. The inserting module technique works in Ruby but not with JRuby and imported Java classes. Any other ideas to stub out the superclass method to get my RSpec test to pass?

  • Two way binding settings problem.

    - by Jamie
    Hi, I am having a problem using two way binding with a listpicker. I am able to set the value using c# but not in the SelectedItem=".." in xaml. The binding is returning the correct value (and is a value in the listpicker) as i have texted it by assigning the text to a textblock. When the page loads, the binding used on the listpicker causes a System.ArgumentOutOfRangeException The code i am using to set it is: // Update a setting value. If the setting does not exist, add the setting. public bool AddOrUpdateValue(string key, Object value) { bool valueChanged = false; try { // If new value is different, set the new value if (settingsStorage[key] != value) { settingsStorage[key] = value; valueChanged = true; } } catch (KeyNotFoundException) { settingsStorage.Add(key, value); valueChanged = true; } catch (ArgumentException) { settingsStorage.Add(key, value); valueChanged = true; } catch (Exception e) { Console.WriteLine("Exception occured whilst using IsolatedStorageSettings: " + e.ToString()); } return valueChanged; } // Get the current value of the setting, if not found, set the setting to default value. public valueType GetValueOrDefault<valueType>(string key, valueType defaultValue) { valueType value; try { value = (valueType)settingsStorage[key]; } catch (KeyNotFoundException) { value = defaultValue; } catch (ArgumentException) { value = defaultValue; } return value; } public string WeekBeginsSetting { get { return GetValueOrDefault<string>(WeekBeginsSettingKeyName, WeekBeginsSettingDefault); } set { AddOrUpdateValue(WeekBeginsSettingKeyName, value); Save(); } } And in the xaml: <toolkit:ListPicker x:Name="WeekStartDay" Header="Week begins on" SelectedItem="{Binding Source={StaticResource AppSettings}, Path=WeekBeginsSetting, Mode=TwoWay}"> <sys:String>monday</sys:String> <sys:String>sunday</sys:String> </toolkit:ListPicker> The StaticResource AppSettings is a resource from a seperate .cs file. <phone:PhoneApplicationPage.Resources> <local:ApplicationSettings x:Key="AppSettings"></local:ApplicationSettings> </phone:PhoneApplicationPage.Resources> Thanks in advance

  • Equality and Assigment Operators

    - by Jeremy Smith
    I have a assembly compiled in VB.NET that contains two operators: Public Shared Operator =(quarterA As CalendarQuarter, quarterB As CalendarQuarter) As Boolean Return quarterA.StartDate = quarterB.StartDate AndAlso quarterA.EndDate = quarterB.EndDate AndAlso quarterA.Quarter = quarterB.Quarter End Operator Public Shared Operator <>(quarterA As CalendarQuarter, quarterB As CalendarQuarter) As Boolean Return Not (quarterA = quarterB) End Operator However, when using the assembly in C# to perform equality checks if (qtr != null) I receive the error: Cannot implicity convert type 'object' to 'bool' My original intent with the = operator was only for assignment purposes in VB, so I may be way off base (I don't use custom operators too often). What do I need to do to make the operator behave with both equality and assignment operations?

  • How to add a timeout value when using Java's Runtime.exec()?

    - by James Adams
    I have a method I am using to execute a command on the local host. I'd like to add a timeout parameter to the method so that if the command being called doesn't finish in a reasonable amount of time the method will return with an error code. Here's what it looks like so far, without the ability to timeout: public static int executeCommandLine(final String commandLine, final boolean printOutput, final boolean printError) throws IOException, InterruptedException { Runtime runtime = Runtime.getRuntime(); Process process = runtime.exec(commandLine); if (printOutput) { BufferedReader outputReader = new BufferedReader(new InputStreamReader(process.getInputStream())); System.out.println("Output: " + outputReader.readLine()); } if (printError) { BufferedReader errorReader = new BufferedReader(new InputStreamReader(process.getErrorStream())); System.out.println("Error: " + errorReader.readLine()); } return process.waitFor(); } Can anyone suggest a good way for me to implement a timeout parameter? Thanks in advance for any suggestions! --James

  • Android getWifiState to String

    - by ahsteele
    I am attempting to get the string representation of an Android device's current WiFi state. I am using the getWifiState() method of the WiFiManager and am getting an integer returned depending on the current state. This makes total sense as getWifiState() is supposed to return an integer. The method's documentation indicates that the possible return values translate to one of the following constant values 0 WIFI_STATE_DISABLING 1 WIFI_STATE_DISABLED 2 WIFI_STATE_ENABLING 3 WIFI_STATE_ENABLED 4 WIFI_STATE_UNKNOWN Is there an easy way to translate the integer returned from getWiFiState() to a string representation? I've looked at getIntExtra but am unsure of its use.

  • Searching for Records

    - by 47
    I've come up with a simple search view to search for records in my app. The user just enters all parameters in the search box then all this is matched against the database, then results are returned. One of these fields is the phone number....now in the database it's stored in the format XXX-XXX-XXX. A search, for example, for "765-4321" pull up only "416-765-4321...however I want it to return both "416-765-4321" and "4167654321" My view is as below: def search(request, page_by=None): query = request.GET.get('q', '') if query: term_list = query.split(' ') q = Q(first_name__icontains=term_list[0]) | Q(last_name__icontains=term_list[0]) | Q(email_address__icontains=term_list[0]) | Q(phone_number__icontains=term_list[0]) for term in term_list[1:]: q.add((Q(first_name__icontains=term) | Q(last_name__icontains=term) | Q(email_address__icontains=term) | Q(phone_number__icontains=term)), q.connector) results = Customer.objects.filter(q).distinct() all = results.count() else: results = [] if 'page_by' in request.GET: page_by = int(request.REQUEST['page_by']) else: page_by = 50 return render_to_response('customers/customers-all.html', locals(), context_instance=RequestContext(request))

  • NAudio: How can I get a event that tells me that the MP3 file reached the end?

    - by Rookian
    I tried to use this: private void CreateDevice() { _playbackDevice = new WaveOut(); _playbackDevice.PlaybackStopped += PlaybackDevicePlaybackStopped; } void PlaybackDevicePlaybackStopped(object sender, EventArgs e) { if (OnPlaybackStopped != null) { OnPlaybackStopped(this, e); } } But it never invoked. Then I tried to use the PlaybackState: public PlaybackState PlaybackState { get { if (_playbackDevice == null) return default(PlaybackState); return _playbackDevice.PlaybackState; } } But when the song ends it does not change to "stopped". But when I call Stopped it changes correctly. Can someone help me?

  • Need to skip newline char (\n) from input file

    - by igor
    I am reading in a file into an array. It is reading each char, the problem arises in that it also reads a newline in the text file. This is a sudoku board, here is my code for reading in the char: bool loadBoard(Square board[BOARD_SIZE][BOARD_SIZE]) { ifstream ins; if(openFile(ins)){ char c; while(!ins.eof()){ for (int index1 = 0; index1 < BOARD_SIZE; index1++) for (int index2 = 0; index2 < BOARD_SIZE; index2++){ c=ins.get(); if(isdigit(c)){ board[index1][index2].number=(int)(c-'0'); board[index1][index2].permanent=true; } } } return true;} return false; } like i said, it reads the file, displays on screen, just not in correct order when it encounters the \n

  • How do I avoid an infinite loop when overriding a virtual property?

    - by cbsch
    Is it possible to ignore set and get when I'm assigning to or retrieving a value? In specific, I'm inheriting from a class that has a property declared like this: virtual public Int32 Value { get; set; } What I'd like to do is to override it and do something useful in those set and get's. The problem appears when I override it, I also have to manually assign, or return the value from the property. If I do something like this: override public Int32 Value { get { return this.Value; } set { this.Value = value; // do something useful } Then I'm creating an infinite loop. Is there a way to set or get the value without invoking the code in set and get, or do I have to make a separate name for the actual variable?

  • Using a type parameter and a pointer to the same type parameter in a function template

    - by Darel
    Hello, I've written a template function to determine the median of any vector or array of any type that can be sorted with sort. The function and a small test program are below: #include <algorithm> #include <vector> #include <iostream> using namespace::std; template <class T, class X> void median(T vec, size_t size, X& ret) { sort(vec, vec + size); size_t mid = size/2; ret = size % 2 == 0 ? (vec[mid] + vec[mid-1]) / 2 : vec[mid]; } int main() { vector<double> v; v.push_back(2); v.push_back(8); v.push_back(7); v.push_back(4); v.push_back(9); double a[5] = {2, 8, 7, 4, 9}; double r; median(v.begin(), v.size(), r); cout << r << endl; median(a, 5, r); cout << r << endl; return 0; } As you can see, the median function takes a pointer as an argument, T vec. Also in the argument list is a reference variable X ret, which is modified by the function to store the computed median value. However I don't find this a very elegant solution. T vec will always be a pointer to the same type as X ret. My initial attempts to write median had a header like this: template<class T> T median(T *vec, size_t size) { sort(vec, vec + size); size_t mid = size/2; return size % 2 == 0 ? (vec[mid] + vec[mid-1]) / 2 : vec[mid]; } I also tried: template<class T, class X> X median(T vec, size_t size) { sort(vec, vec + size); size_t mid = size/2; return size % 2 == 0 ? (vec[mid] + vec[mid-1]) / 2 : vec[mid]; } I couldn't get either of these to work. My question is, can anyone show me a working implementation of either of my alternatives? Thanks for looking!

  • NSRangeException Issue

    Hi, I am writing a Core Data-based iPhone app and I am new to Objective-C. I have a bug that I am really struggling to nail. The iPhone simulator keeps crashing with the following error message: 2010-03-21 17:37:40.583 Patients[3689:207] * Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray insertObject:atIndex:]: index (1) beyond bounds (1)' 2010-03-21 17:37:40.585 Patients[3689:207] Stack: ( 31007835, 2516698377, 31091771, 31091610, 601273, 197333, 3194546, 3141378, 25020, 29768673, 214570, 30740485, 204512, 29114749, 29505379, 29001194, 29252410, 29190487, 30794322, 30791263, 30788680, 39097877, 39098074, 2883503, 9912, 9766 ) This error happens when I press return on a textField. What happens when the return key is pressed is that an attribute on an entity is updated. I don't know what array is out of bounds as I am not using any arrays in my code! Is there any way of getting more detail as to where in my code the error is?? Thanks,

  • javascript select box hanging on second select in ie7

    - by bsandrabr
    I have a drop down select box inside a div. When the user clicks on change, a dropdown box appears next to the change/submit button and the user makes a selection which then updates the db and the selection appears instead of the dropdown. All works fine in IE8 and firefox but in IE7 it allows one selection (there are several identical dropdowns) but the second time a selection is made it hangs on please wait. This is the relevant code <td width=200> <input type="button" onclick="startChanging(this)" value="Change" /></td> <script type="text/javascript"> var selectBox, isEditing = false; var recordvalue; if( window.XMLHttpRequest ) { recordvalue = new XMLHttpRequest(); } else if( window.ActiveXObject ) { try { recordvalue = new ActiveXObject('Microsoft.XMLHTTP'); } catch(e) {} } window.onload = function () { selectBox = document.getElementById('changer'); selectBox.id = ''; selectBox.parentNode.removeChild(selectBox); }; function startChanging(whatButton) { if( isEditing && isEditing != whatButton ) { return; } //no editing of other entries if( isEditing == whatButton ) { changeSelect(whatButton); return; } //this time, act as "submit" isEditing = whatButton; whatButton.value = 'Submit'; var theRow = whatButton.parentNode.parentNode; var stateCell = theRow.cells[3]; //the cell that says "present" stateCell.className = 'editing'; //so you can use CSS to remove the background colour stateCell.replaceChild(selectBox,stateCell.firstChild); //PRESENT is replaced with the select input selectBox.selectedIndex = 0; } function changeSelect(whatButton) { isEditing = true; //don't allow it to be clicked until submission is complete whatButton.value = 'Change'; var stateCell = selectBox.parentNode; var theRow = stateCell.parentNode; var editid = theRow.cells[0].firstChild.firstChild.nodeValue; //text inside the first cell var value = selectBox.firstChild.options[selectBox.firstChild.selectedIndex].value; //the option they chose selectBox.parentNode.replaceChild(document.createTextNode('Please wait...'),selectBox); if( !recordvalue ) { //allow fallback to basic HTTP location.href = 'getupdate.php?id='+editid+'&newvalue='+value; } else { recordvalue.onreadystatechange = function () { if( recordvalue.readyState != 4 ) { return; } if( recordvalue.status >= 300 ) { alert('An error occurred when trying to update'); } isEditing = false; newState = recordvalue.responseText.split("|"); stateCell.className = newState[0]; stateCell.firstChild.nodeValue = newState[1] || 'Server response was not correct'; }; recordvalue.open('GET', "getupdate.php?id="+editid+"&newvalue="+value, true); recordvalue.send(null); } } </script> If anyone has any idea why this is happening I'd be very grateful

  • Can I make Axis2 generate a WSDL with 'unwrapped' types?

    - by Bedwyr Humphreys
    I'm trying to consume a hello world AXIS2 SOAP web service using a PHP client. The Java class is written in Netbeans and the AXIS2 aar file is generated using the Netbeans AXIS2 plugin. You've all seen it before but here's the java class: public class SOAPHello { public String sayHello(String username) { return "Hello, "+username; } } The wsdl genereated by AXIS2 seems to wrap all the parameters so that when I consume the service i have to use a crazy PHP script like this: $client = new SoapClient("http://myhost:8080/axis2/services/SOAPHello?wsdl"); $parameters["username"] = "Dave"; $response = $client->sayHello($parameters)->return; echo $response."!"; When all I really want to do is echo $client->sayHello("Dave")."!"; My question is two-fold: why is this happening? and what can I do to stop it? :) Here's are the types, message and porttype sections of the generated wsdl: <wsdl:types> <xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="http://soap.axis2.myhost.co.uk"> <xs:element name="sayHello"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="username" nillable="true" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="sayHelloResponse"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="return" nillable="true" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> </wsdl:types> <wsdl:message name="sayHelloRequest"> <wsdl:part name="parameters" element="ns:sayHello"/> </wsdl:message> <wsdl:message name="sayHelloResponse"> <wsdl:part name="parameters" element="ns:sayHelloResponse"/> </wsdl:message> <wsdl:portType name="SOAPHelloPortType"> <wsdl:operation name="sayHello"> <wsdl:input message="ns:sayHelloRequest" wsaw:Action="urn:sayHello"/> <wsdl:output message="ns:sayHelloResponse" wsaw:Action="urn:sayHelloResponse"/> </wsdl:operation> </wsdl:portType>

  • Using a helper method in a mailer that is defined in a controller

    - by Horace Loeb
    The helper method current_user is defined and made available as a helper in ApplicationController like this: class ApplicationController < ActionController::Base helper_method :current_user def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end end My question is how I can use the current_user helper method in a mailer template (obviously it will always return nil, but I'm trying to render a partial that depends on it). Normally when I want to use helpers in a mailer, I do something like add_template_helper(SongsHelper), but since the helper is defined in a class instead of a module I'm not sure what to do
