  • How to get width of button in DateTimePicker-Control/Controls in general?

    - by Inno
    Hello everybody, I implemented a custom DateTimePicker. On the DateTimePicker there is a button. In the examples I've found it's width is set to 16. This is working but I would like to have a dynamic approach. So, is there a way to get the size of this button or is there a general way to get information about .Net-Control sub elements like size etc.? Trying DateTimePicker.Controls didn't help me (it's empty).

  • Representing xml through a single class

    - by Charles
    I am trying to abstract away the difficulties of configuring an application that we use. This application takes a xml configuration file and it can be a bit bothersome to manually edit this file, especially when we are trying to setup some automatic testing scenarios. I am finding that reading xml is nice, pretty easy, you get a network of element nodes that you can just go through and build your structures quite nicely. However I am slowly finding that the reverse is not quite so nice. I want to be able to build a xml configuration file through a single easy to use interface and because xml is composed of a system of nodes I am having a lot of struggle trying to maintain the 'easy' part. Does anyone know of any examples or samples that easily and intuitively build xml files without declaring a bunch of element type classes and expect the user to build the network themselves? For example if my desired xml output is like so <cook version="1.1"> <recipe name="chocolate chip cookie"> <ingredients> <ingredient name="flour" amount="2" units="cups"/> <ingredient name="eggs" amount="2" units="" /> <ingredient name="cooking chocolate" amount="5" units="cups" /> </ingredients> <directions> <direction name="step 1">Preheat oven</direction> <direction name="step 2">Mix flour, egg, and chocolate</direction> <direction name="step 2">bake</direction> </directions> </recipe> <recipe name="hot dog"> ... How would I go about designing a class to build that network of elements and make one easy to use interface for creating recipes? Right now I have a recipe object, an ingredient object, and a direction object. The user must make each one, set the attributes in the class and attach them to the root object which assembles the xml elements and outputs the formatted xml. Its not very pretty and I just know there has to be a better way. I am using python so bonus points for pythonic solutions

  • cannot convert from string to system.windows.forms.string iwin32window

    - by Michael Quiles
    This is supposed to show the winner in the xWinner form label but I cant figure it out. xWinnerForm.Show(b1.Text);. I'm new to c# so can you please explain in layman terms thanks. static public bool CheckWinner(Button[] myControls) { bool gameOver = false; for (int i = 0; i < 8; i++) { int a = Winners[i, 0]; int b = Winners[i, 1]; int c = Winners[i, 2]; Button b1 = myControls[a], b2 = myControls[b], b3 = myControls[c]; if (b1.Text == "" || b2.Text == "" || b3.Text == "") continue; if (b1.Text == b2.Text && b2.Text == b3.Text) { gameOver = true; Form xWinnerForm = new xWinnerForm(); xWinnerForm.Show(b1.Text); } public void Show(string text) { this.xWinnerLabel.Text = text; this.Show(); } } return gameOver; }

  • JPA: persisting object, parent is ok but child not updated

    - by James.Elsey
    Hello, I have my domain object, Client, I've got a form on my JSP that is pre-populated with its data, I can take in amended values, and persist the object. Client has an abstract entity called MarketResearch, which is then extended by one of three more concrete sub-classes. I have a form to pre-populate some MarketResearch data, but when I make changes and try to persist the Client, it doesn't get saved, can someone give me some pointers on where I've gone wrong? My 3 domain classes are as follows (removed accessors etc) public class Client extends NamedEntity { @OneToOne @JoinColumn(name = "MARKET_RESEARCH_ID") private MarketResearch marketResearch; ... } @Inheritance(strategy = InheritanceType.JOINED) public abstract class MarketResearch extends AbstractEntity { ... } @Entity(name="MARKETRESEARCHLG") public class MarketResearchLocalGovernment extends MarketResearch { @Column(name = "CURRENT_HR_SYSTEM") private String currentHRSystem; ... } This is how I'm persisting public void persistClient(Client client) { if (client.getId() != null) { getJpaTemplate().merge(client); getJpaTemplate().flush(); } else { getJpaTemplate().persist(client); } } To summarize, if I change something on the parent object, it persists, but if I change something on the child object it doesn't. Have I missed something blatantly obvious? Thanks

  • casting doubles to integers in order to gain speed

    - by antirez
    Hello all, in Redis (http://code.google.com/p/redis) there are scores associated to elements, in order to take this elements sorted. This scores are doubles, even if many users actually sort by integers (for instance unix times). When the database is saved we need to write this doubles ok disk. This is what is used currently: snprintf((char*)buf+1,sizeof(buf)-1,"%.17g",val); Additionally infinity and not-a-number conditions are checked in order to also represent this in the final database file. Unfortunately converting a double into the string representation is pretty slow. While we have a function in Redis that converts an integer into a string representation in a much faster way. So my idea was to check if a double could be casted into an integer without lost of data, and then using the function to turn the integer into a string if this is true. For this to provide a good speedup of course the test for integer "equivalence" must be fast. So I used a trick that is probably undefined behavior but that worked very well in practice. Something like that: double x = ... some value ... if (x == (double)((long long)x)) use_the_fast_integer_function((long long)x); else use_the_slow_snprintf(x); In my reasoning the double casting above converts the double into a long, and then back into an integer. If the range fits, and there is no decimal part, the number will survive the conversion and will be exactly the same as the initial number. As I wanted to make sure this will not break things in some system, I joined #c on freenode and I got a lot of insults ;) So I'm now trying here. Is there a standard way to do what I'm trying to do without going outside ANSI C? Otherwise, is the above code supposed to work in all the Posix systems that currently Redis targets? That is, archs where Linux / Mac OS X / *BSD / Solaris are running nowaday? What I can add in order to make the code saner is an explicit check for the range of the double before trying the cast at all. Thank you for any help.

  • backbone.js - Having multiple instances of the same view

    - by TrueWheel
    I am having problems having multiple instances in of the same view in different div elements. When I try to initialize them only the second of the two elements appear no matter what order I put them in. Here is the code for my view. var BodyShapeView = Backbone.View.extend({ thingiview: null, scene: null, renderer: null, model: null, mouseX: 0, mouseY: 0, events:{ 'click button#front' : 'front', 'click button#diag' : 'diag', 'click button#in' : 'zoomIn', 'click button#out' : 'zoomOut', 'click button#on' : 'rotateOn', 'click button#off' : 'rotateOff', 'click button#wireframeOn' : 'wireOn', 'click button#wireframeOff' : 'wireOff', 'click button#distance' : 'dijkstra' }, initialize: function(name){ _.bindAll(this, 'render', 'animate'); scene = new THREE.Scene(); camera = new THREE.PerspectiveCamera( 15, 400 / 700, 1, 4000 ); camera.position.z = 3; scene.add( camera ); camera.position.y = -5; var ambient = new THREE.AmbientLight( 0x202020 ); scene.add( ambient ); var directionalLight = new THREE.DirectionalLight( 0xffffff, 0.75 ); directionalLight.position.set( 0, 0, 1 ); scene.add( directionalLight ); var pointLight = new THREE.PointLight( 0xffffff, 5, 29 ); pointLight.position.set( 0, -25, 10 ); scene.add( pointLight ); var loader = new THREE.OBJLoader(); loader.load( "img/originalMeanModel.obj", function ( object ) { object.children[0].geometry.computeFaceNormals(); var geometry = object.children[0].geometry; console.log(geometry); THREE.GeometryUtils.center(geometry); geometry.dynamic = true; var material = new THREE.MeshLambertMaterial({color: 0xffffff, shading: THREE.FlatShading, vertexColors: THREE.VertexColors }); mesh = new THREE.Mesh(geometry, material); model = mesh; // model = object; scene.add( model ); } ); // RENDERER renderer = new THREE.WebGLRenderer(); renderer.setSize( 400, 700 ); $(this.el).find('.obj').append( renderer.domElement ); this.animate(); }, Here is how I create the instances var morphableBody = new BodyShapeView({ el: $("#morphable-body") }); var bodyShapeView = new BodyShapeView({ el: $("#mean-body") }); Any help would be really appreciated.

  • Generate XSD from 2005 SQL Server Database

    - by Robert Finlayson
    What is the easiest method to generate an XSD schema from a 2005 SQL Server Database? Would it be possible to generate one XSD schema for the entire Database (~100 tables)? I searched online and found a SQL example that generates one XSD for the one table: DECLARE @schema xml SET @schema = (SELECT * FROM MyTableName FOR XML AUTO, ELEMENTS, XMLSCHEMA('MyTableNameSchema')) SELECT @schema Outside of SQL Server, is there a third party tool that could generate the XSD file from the 2005 Database?

  • S.redirectTo leads always to a blank screen

    - by Jaime Ocampo
    I am now playing a little bit with lift (2.8.0), and all the features in LiftRules work as intended. But I haven't been able to use S.redirectTo at all. I always ends with a blank screen, no matter what. No error messages at all! As an example, I have the following form: ... <lift:logIn.logInForm form="post"> <p><login:name /></p> <p><login:password /></p> <p><login:submit /></p> </lift:logIn.logInForm> ... And the code is: object LogIn extends helper.LogHelper { ... def logInForm(in: NodeSeq): NodeSeq = { var name = "" var password = "" def login() = { logger.info("name: " + name) logger.info("password: " + password) if (name == "test1") S.redirectTo("/example") if (name == "test2") S.redirectTo("/example.html") if (name == "test3") S.redirectTo("example.html") S.redirectTo("/") } bind("login", in, "name" -> SHtml.text(name, name = _), "password" -> SHtml.password(password, password = _), "submit" -> SHtml.submit("Login", login)) } } The method 'login' is invoked, I can check that in the log information. But as I said, no matter which name I enter, I always end with a blank screen, although 'examples.html' is available when being accessed directly in the browser. How should I invoke S.redirectoTo in order to navigate to 'examples.html'? Also, why don't I receive an error message (I am logging at a debug level)? I think all the configuration in Boot is correct, since all LitRules examples (statelessRewrite, dispatch, viewDispatch, snippets) work fine.

  • Get node value from document

    - by J Noel
    I have XML in PHP, I am trying to get the value of the status node: <?xml version="1.0" encoding="utf-8" ?> <response> <result> <form name="MREP"> <update> <criteria> <field name="Serial_Number" compOperator="Equals" value="A-000-1012"></field> <reloperator>AND</reloperator> <field name="MREP_Type" compOperator="Equals" value="0"></field> </criteria> <newvalues> <field name="Is_being_Used"> <value><![CDATA[TRUE]]></value> </field> </newvalues> <status>Success</status> </update> </form> </result> </response> I tried $xml = simplexml_load_string($mrepValide); echo $xml->status; (where $mrepValide is a string of XML shown above) But I think it didnt work since status is not the parent node. Any help would be greatly appreciated.

  • Why is FBJS dropping my 'onclick' attribute from this input element?

    - by Chris Barnhill
    When I include an 'onClick' attribute in setInnerXTHML() like this: var innerHtml = '<span>Build Track: Select a city where track building should begin'+ '<div id="action-end">'+ '<form>'+ '<input type="button" value="End Track Building" id="next-phase" onClick="moveTrainAuto();" />'+ '</form>'+ '</div></span>'; actionPrompt.setInnerXHTML(innerHtml); var btn = document.getElementById('next-phase'); btn.addEventListener('click', 'moveTrainAuto'); The 'onClick' gets dropped. I know this from inspecting the element with Firebug. This is what it reveals: <input id="app148184604666_next-phase" type="button" value="End Track Building"/> Here is the function called for onClick: function moveTrainAuto(evt) { debugger; ajax = new Ajax(); ajax.responseType = Ajax.JSON; ajax.ondone = function(data) { debugger; if(data.code == 'UNLOAD_CARGO') { unloadCargo(); } else if (data.code == 'MOVE_TRAIN_AUTO') { moveTrainAuto(); } else if (data.code == 'TURN_END') { turnEnd(); } else { /* handle error */ } } ajax.post(baseURL + '/turn/move-trains-auto'); } As you can see, I've tried both 'onClick' and 'addEventListener'. Neither works. Any ideas?

  • VB.NET Two different approaches to generic cross-threaded operations; which is better?

    - by BASnappl
    VB.NET 2010, .NET 4 Hello, I recently read about using SynchronizationContext objects to control the execution thread for some code. I have been using a generic subroutine to handle (possibly) cross-thread calls for things like updating UI controls that utilizes Invoke. I'm an amateur and have a hard time understanding the pros and cons of any particular approach. I am looking for some insight on which approach might be preferable and why. Update: This question is motivated, in part, by statements such as the following from the MSDN page on Control.InvokeRequired. An even better solution is to use the SynchronizationContext returned by SynchronizationContext rather than a control for cross-thread marshaling. Method 1: Public Sub InvokeControl(Of T As Control)(ByVal Control As T, ByVal Action As Action(Of T)) If Control.InvokeRequired Then Control.Invoke(New Action(Of T, Action(Of T))(AddressOf InvokeControl), New Object() {Control, Action}) Else Action(Control) End If End Sub Method 2: Public Sub UIAction(Of T As Control)(ByVal Control As T, ByVal Action As Action(Of Control)) SyncContext.Send(New Threading.SendOrPostCallback(Sub() Action(Control)), Nothing) End Sub Where SyncContext is a Threading.SynchronizationContext object defined in the constructor of my UI form: Public Sub New() InitializeComponent() SyncContext = WindowsFormsSynchronizationContext.Current End Sub Then, if I wanted to update a control (e.g., Label1) on the UI form, I would do: InvokeControl(Label1, Sub(x) x.Text = "hello") or UIAction(Label1, Sub(x) x.Text = "hello") So, what do y'all think? Is one way preferred or does it depend on the context? If you have the time, verbosity would be appreciated! Thanks in advance, Brian

  • How do I determine whether calculation was completed, or detect interrupted calculation?

    - by BenTobin
    I have a rather large workbook that takes a really long time to calculate. It used to be quite a challenge to get it to calculate all the way, since Excel is so eager to silently abort calculation if you so much as look at it. To help alleviate the problem, I created some VBA code to initiate the the calculation, which is initiated by a form, and the result is that it is not quite as easy to interrupt the calculation process, but it is still possible. (I can easily do this by clicking the close X on the form, but I imagine there are other ways) Rather than taking more steps to try and make it harder to interrupt calculation, I'd like to have the code detect whether calculation is complete, so it can notify the user rather than just blindly forging on into the rest of the steps in my code. So far, I can't find any way to do that. I've seen references to Application.CalculationState, but the value is xlDone after I interrupt calculation, even if I interrupt the calculation after a few seconds (it normally takes around an hour). I can't think of a way to do this by checking the value of cells, since I don't know which one is calculated last. I see that there is a way to mark cells as "dirty" but I haven't been able to find a way to check the dirtiness of a cell. And I don't know if that's even the right path to take, since I'd likely have to check every cell in every sheet. The act of interrupting calculation does not raise an error, so my ON ERROR doesn't get triggered. Is there anything I'm missing? Any ideas? Any ideas?

  • Change css property in chain - JavaScript

    - by SilverDeveloper
    I'm using MooTools 1.4.5 and I want to change cursor before calling function that takes some time and after finished same function set cursor to default. I was not successful. After that I made simple example to change background color via plain JavaScript (no jQuery or MooTools plugin) and again I was not successful. Here is my code. <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> </div> </form> </body> <script type="text/javascript"> <!-- document.body.style.background = 'red'; setTimeout(function () { }, 1250); document.body.style.background = 'yellow'; //--> </script> </html> First at all I set background color to red, and after delay to yellow. I assumed that the background color will bi set to red and after delay to yellow. It doesn't work. When page is loaded background color is yellow (last line). If I insert alert function in a middle of lines where sets background color everything works fine (background color is red, click to message box, background color is yellow). Why it works so? Only last changing style is affected. I need something like that to change pointer before calling function that takes 10 seconds and setting cursor to default value after function is done.

  • Stopping work from one thread using another thread

    - by 113483626144458436514
    Not sure if my title is worded well, but whatever :) I have two threads: the main thread with the work that needs to be done, and a worker thread that contains a form with a progress bar and a cancel button. In normal code, it would be the other way around, but I can't do that in this case. When the user clicks the cancel button, a prompt is displayed asking if he wants to really cancel the work. The problem is that work continues on the main thread. I can get the main thread to stop work and such, but I would like for it to stop doing work when he clicks "Yes" on the prompt. Example: // Main thread work starts here t1 = new Thread(new ThreadStart(progressForm_Start)); t1.Start(); // Working for (i = 0; i <= 10000; i++) { semaphore.WaitOne(); if (pBar.Running) bgworker_ProgressChanged(i); semaphore.Release(); if (pBar.IsCancelled) break; } t1.Abort(); // Main thread work ends here // Start progress bar form in another thread void progressForm_Start() { pBar.Status("Starting"); pBar.ShowDialog(); } I could theoretically include a prompt in the cancelWatch() function, but then I would have to do that everywhere I'm implementing this class.

  • Handling row selection from a simple grid using jquery and asp.net mvc

    - by Jonn
    Using a simple table and jquery, how would you manually handle selection using jquery? So far, I've managed to add a gridrowselected class on the tr when the click event is called so that I'll know which row is currently selected. But I don't know how to pass the selected data back to the controller (or at least an index I placed on the row). I tried something like this $(function() { $('#ProjectList .gridrow').click(function() { // Get row's index var projectId = $(this).find('input[name$=ProjectId]').val(); // Remove the input if it already exists var parentForm = $(this).parents('form'); parentForm.remove('input[name="selectedRows"][value="' + projectId + '"]'); // If it is selected, create the form. If it's not selected then the input just gets removed (the user must have clicked on it and deselected the row) if ($(this).hasClass('gridrow-selected') === true) { parentForm.append($('<input>', { type: "hidden", name: "selectedRows", value: projectId })); } }); }); which I'm expecting to create a hidden input so that when I post, selectedRows gets passed onto the controller. But all it does is create the input, but the data still doesn't get passed to the controller.

    Should we always try to not to give "height" to elements in XHTML through CSS? if yes the i think min-height would be better idea instead of fixed height. What cross browser( including IE6), W3C valid css, non-javascript "min-height" method in css? if i add min-height to any tag example <div> then in future in more content comes in then will we have to change height of div or if min-height is defined then no need.
