  • JTable - Getting a cell into Edit mode on pressing Tab

    - by Luhar
    This is possibly has a trivial solution, but I am at the end of my tether so I hope somebody can help out. I use a JTable which has a custom renderer and a custom editor for a set of columns. The renderer uses a JLabel component and the editor uses a JSpinner component. Our users want to be able to enter values in a column, and then press TAB or ENTER to move to the next editable cell in the table. If I understand correctly, this is the default behaviour for a JTable. However, this doesn't seem to work correctly for me. Until the user clicks on the cell, only the JLabel is displayed. The JSpinner (i.e. CellEditor) is only displayed when a user double clicks on the cell. So, it looks like the cell is going into "edit" mode only on MouseEvents, but not when it has focus. How do I get the cell to go into edit mode as soon as it has focus?

  • How do I extend a WPF application using an addin-like architeture?

    - by Thiado de Arruda
    Lets say I have a WPF application that shows a ListBox with an ArrayList -populated with objects of arbitrary types- as a source, and this application is hosted in an assembly 'A'. By default the ListBox will display the custom object 'ToString' method return value. If a data template for that object type is found, the ListBox will use it for rendering. Imagine that theres another assembly 'B' that references of 'A' and seeks to extend it by providing custom data templates for certain types, to be used in that ListBox. Is there some way to do that without 'A'being aware of B?

  • Memory Leak with jQuery UI inside UpdatePanel in ie7

    - by Ryan
    I have a fairly complex asp.net page based on UpdatePanels and jQuery UI. Unfortunately, when the panels update, the jQuery UI widgets leak memory like crazy in ie7, even if I manually 'destroy' them. Does anyone know a technique/patch to prevent these leaks? I've created a simple example page with a slider inside an UpdatePanel. Just click the 'Leak' button and refresh the page to see the leak in sieve. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Leak2.aspx.cs" Inherits="Leak2" %> <%@ Register Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Namespace="System.Web.UI" TagPrefix="asp" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Leak</title> <link type="text/css" href="/jquery/css/custom-theme/jquery-ui-1.7.2.custom.css" rel="Stylesheet" /> <script type="text/javascript" src="/jquery/js/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="/jquery/js/jquery-ui-1.7.2.custom.min.js"></script> </head> <body> <form id="form1" runat="server"> <div> <script type="text/javascript"> function initializeSlider() { $(".slider").slider({ min: 0, max: 100, value: 100, step: 5 }); } $(document).ready(function() { initializeSlider(); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(function() { initializeSlider(); }); }); </script> <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <div style="width: 300px;"> <div class="slider"></div> <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Leak" /> </div> </ContentTemplate> </asp:UpdatePanel> </div> </form> </body> </html>

  • Python metaprogramming help

    - by Timmy
    im looking into mongoengine, and i wanted to make a class an "EmbeddedDocument" dynamically, so i do this def custom(cls): cls = type( cls.__name__, (EmbeddedDocument,), cls.__dict__.copy() ) cls.a = FloatField(required=True) cls.b = FloatField(required=True) return cls A = custom( A ) and tried it on some classes, but its not doing some of the base class's init or sumthing in BaseDocument def __init__(self, **values): self._data = {} # Assign initial values to instance for attr_name, attr_value in self._fields.items(): if attr_name in values: setattr(self, attr_name, values.pop(attr_name)) else: # Use default value if present value = getattr(self, attr_name, None) setattr(self, attr_name, value) but this never gets used, thus never setting ._data, and giving me errors. how do i do this?

  • Best practices for displaying large number of images as thumbnails in c#

    - by andySF
    I got to a point where it's very difficult to get answers by debugging and tracing object, so i need some help. What I'm trying to do: A history form for my screen capture pet project. The history must list all images as thumbnails (ex: picasa). What I've done: I created a HistoryItem:UserControl. This history item has a few buttons, a check box, a label and a picture box. The buttons are for delete/edit/copy image. The check box is used for selecting one or more images and the label is for some info text. The picture box is getting the image from a public property that is a path and a method creates a proportional thumbnail to display it when the control has been loaded. This user control has two public events. One for deleting the image and one for bubbling the events for mouse enter and mouse leave trough all controls. For this I use EventBroadcastProvider. The bubbling is useful because wherever I move the mouse over the control, the buttons appear. The dispose method has been extended and I manually remove the events. All images are loaded by looping a xml file that contains the path of all images. For each image in this XML I create a new HitoryItem that is added (after a little coding to sort and limit the amount of images loaded) to a flow layout panel. The problem: When I lunch the history form, and the flow layout panel is populated with my HistoryItem custom control, my memory usage increases drastically.From 14Mb to around 100MB with 100 images loaded. By closing the history form and disposing whatever I could dispose and even trying to call GC.Collect() the memory increase remain. I search for any object that could not be disposed properly like an image or event but wherever I used them they are disposed. The problem seams to be from multiple sources. One is that the events for bubbling are not disposing properly, and the other is from the picture box itself. All of this i could see by commenting all the code to a limited version when only the custom control without any image processing and even events is loaded. Without the events the memory consumption is reduced by axiomatically 20%. So my real question is if this logic, flow layout panels and custom controls with picture boxes, is the best solution for displaying large amounts of images as thumbnails. Thank you!

  • Looking for a new, free firewall (Sunbelt has a huge hole)

    - by Jason
    I've been using Sunbelt Personal Firewall v. 4.5 (previously Kerio). I've discovered that blocking Firefox connections in the configuration doesn't stop EXISTING Firefox connections. (See my post here yesterday http://superuser.com/questions/132625/sunbelt-firewall-4-5-wont-block-firefox) The "stop all traffic" may work on existing connections - but I'm done testing, as I need to be able to be selective, at any time. I was using the free version, so the "web filtering" option quit working after some time (mostly blocking ads and popups), but I didn't use that anyway. I used the last free version of Kerio before finally having to go to Sunbelt, because Kerio had an unfixed bug where you'd eventually get the BSOD and have to reset Kerio's configuration and start over (configure everything again). So I'm looking for a new Firewall. I don't like ZoneAlarm at all (no offense to all it's users that may be here - personal taste). I need the following: (Sunbelt has all these, except *) - 1. Be able to block in/out to localhost (trusted)/internet selectively for each application with a click (so there's 4 click boxes for each application) [*that effects everything immediately, regardless of what's already connected]. When a new application attempts a connection, you get an allow/deny/remember windows. - 2. Be able to easily set up filter rules for 'individual application'/'all applications,' by protocol, port/address (range), local, remote, in, out. [*Adding a filter rule also doesn't block existing connections in Sunbelt. That needs to work too.] - 3. Have an easy-to-get-to way to "stop all traffic" (like a right click option on the running icon in the task bar). - 4. Be able to set trusted/internet in/out block/allowed (4 things per item) for each of IGMP, ping, DNS, DHCP, VPN, and broadcasts. - 5. Define locahost as trusted/untrusted, define adapter connections as trusted/untrusted. - 6. Block incoming connetions during boot-up and shutdown. - 7. Show existing connections, including local & remote ip/port, protocol, current speed, total bytes transferred, and local ports opened for Listening. - 8. An Intrusion Prevention System which blocks (optionally select each one) known intrustions (long list). - 9. Block/allow applications from starting other applications (deny/allow/remember window). Wish list: A way of knowing what svchost.exe is doing - who is actually using it/calling it. I allowed it for localhost, and selectively allowed it for internet each time the allow/deny window came up. Thanks for any help/suggestions. (I'm using Windows XP SP3.)

  • git private server error: "Permission denied (publickey)."

  • best app to stream movies over the web

    Hi. I have an old box that I'd like to use as a private sever to stream movies off of. My upload speed is about 0.5/Mb/s, so I need something that compresses well. I'd like to be able to access these movies from anywhere, through the web, through some interface (maybe the divx web player? flash player? some other protocol?) Can anyone recommend anything good? (Using Windows XP) Thanks!

  • How can I use different metadata for a Dynamic Data form view and the list view?

    - by ProfK
    We often need a summarised list view with more detailed form view. So far, the only two way I can think of doing this are using a 'custom' list or form view than uses a sumplimentary 'remove' or 'add' list of fields anb generalise this over all entity sets, or create a custom metadata provider that infers somehow which columns to supply. Are there any other ways of distinguishing these two views? PS, I wrote a fun little general details page, that handles insert, edit, and view, all on one page template. Maybe I could somehow use that? It's here.

  • better understanding of JSF Life cycle

    - by gurupriyan.e
    I need your help to understand this better. This is my case. I have a custom validator for each of my input controls in the form. So when there is any validation error,I add a corresponding FacesMessage in the validate method. My understanding was that when there is any validation error - or when there are any FacesMessages added in the validate method of the Custom Validator, it would skip the INVOKE APPLICATION phase and would directly call the RENDER RESPONSE PHASE - showing the FacesMessage that was added in the PROCESS VALIDATION Phase - Is this correct? The problem I'm facing is - I add a FacesMessage in the PROCESS VALIDATION Phase - because of a validation error - and I add a confirmation message for the action that was taken by the user in the INVOKE APPLICATION PHASE - Now both are shown in the page in the RENDER RESPONSE Phase ? - If my understanding is correct in the above question - is it the best practice to conditionally add a confirmation FacesMessage after confirming that there are no FacesMessages in the currect FacesContext ? Appreciate your help.

  • Developing a jQuery plugin that returns a given object, instead of jQuery object itself!

    - by mehdi5275
    Hi, Consider the following base code: (function($) { $.fn.myPlugin = function(settings) { return this.each(function() { //whatever }); }; }); The plugin returns a jQuery object. The question is how am I supposed to write a plugin that returns a custom object so that I can do something like this: var api = $('div.myelement').myPlugin(); api.onMyEventName(function(e, whateverParam) { //whatever }); It'd be highly appreciated if you could write some lines of code that describes me how to do that, how to call the onMyEventName function on a custom api object... Thanks.

  • How to presist the user authentication in SL3 + RIA

    - by Nair
    I am developing SL3 + RIA services with custom authentication. I followed the example in http://code.msdn.microsoft.com/RiaServices/Release/ProjectReleases.aspx?ReleaseId=2661 to implement custom authentication. Based on the implementation, you first do login request from client to service. This request is async process. Since login is async, the control will go back to GUI which then starts to do data bind in SL controls using RIA services, the services happens to requires the authentication to be successful (by adding [RequireAuthentication] attribute). The trouble is, since you requested login might not have completed before the data binding starts t this stage the authentication is false because of that data binding will fail. I would like to know if you require your web services to have 'RequireAuthentication' how would you wait for authentication to complete at the server side or client side. Appriciate the help. Thanks,

  • How can I make a UIPickerView like a UIDatePicker?

    - by iamthepiguy
    I have a custom UIViewController subclass which acts as Datasource and Delegate for a UIPickerView which I would like to serve two different purposes, as each are simple enough, and don't really warrant separate files. One operation must be as a custom picker, and this works fine. However, for the other operation, I want it to act just like a UIDatePicker. The problem is, UIDatePicker is a subclass of UIControl, not UIPickerView. Is there any sort of enum value I can set in a method (or other way) that will set the UIPickerView to act as a date picker? Or do I have to make two completely different classes and use them differently (pain in the ass)?

  • How to specify the left, right, or title View button in XIB

    - by Sharen Eayrs
    I do not want to create a custom navigation bar. I am pushing a UIViewController and I want to customize how the navigation bar looks for that UIViewController In story board, we just specify the segue and a nav bar show up on the screen. We just drag and drop UIBarItem to the left and right. In XIB, the navigationBar simply doesn't show up. I can add navigation Item but the one I added is ignored. I've heard that there used to be an outlet called navigationItem but it's deprecated for reason I do not know. I can add UINavigationBar, however that would be adding my own custom bar. I want the navBar that's provided by UINavigationController.

In the outbound SMTP server traffic, I see the internal machine name (exchange.domain.local), and the internal ip address (10.10.10.55). The question is, how do you remove this header from exchange, or change it to have the external machine name/ip addresses. I am not talking about the HELO / EHLO handshake as part of the protocol.

  • WPF Binding not updating when binded object is updated

    - by Chris Klepeis
    I'm trying to bind to a custom control like so: <my:GanttChartTaskListView Name="ganttChartTaskListView1" ItemsSource="{Binding Source={x:Static local:TaskCollection.taskList}}" /> In my WPF Window constructor I add add an item to my taskList, when it loads I can see that item in my custom control, however, when I subsequently add items it does not update. I tried setting Mode=TwoWay, however, then it says the "Path" is required and I'm not familiar with binding like that (this is new to me). Here is my TaskCollection class: namespace ProjectManager { public static class TaskCollection { private static List<TaskItem> _taskList = new List<TaskItem>(); public static List<TaskItem> taskList { get {return _taskList; } set { _taskList = value; } } } } Any ideas? Is there a better / easier way to do this?

  • How can I launch an application as Administrator after a WiX MSI has completed?

    - by ray dey
    Hi there I want to launch an application with admin rights after I have completed an installation using a WiX based MSI. I can launch the application just fine, on XP but with Windows 7, it's an issue. The application has a manifest embedded in it that says it should run as administrator and I've changed the impersonate attribute in the Custom Action to "no". I can't change the execute attribute to deferred, as this only works before the InstallFinalize action and I need it after the user has clicked Finish in the MSI. This is my Custom Action: <CustomAction Id="LaunchApp" FileKey="App" ExeCommand="[Command Line Args]" Execute="immediate" Impersonate="no" Return="asyncNoWait" /> Any help on this would be appreciated.
