  • Hidden Features of Visual Studio winforms designer

    - by CodingBarfield
    One of the most loved and hated feautures of visual studio must be the form designer. Creating a simple form/user control layout usually is a breeze. Setting properties and adding events is easy. Setting up the toolbox to use you own controls can be a bit harder and getting the ToolBoxIcons to show up can be a pain. Using third party components by visual inheritance can throw of the designer. And using multiple inheritance on designerables can be really hard. So what are your favorite 'hidden' and or obvious visual studio designer features.

  • sproutcore - todos tutorial, addbutton not responding in firefox

    - by kristian nissen
    I'm testing the sproutcore todo's tutorial and I have checked the code in step-5 and it's identical to my code at least as far as I can see, but the addButton is not responding to click events. addTask: function () { var task; task = Sinatra.store.createRecord(Sinatra.Task, { 'description': 'New Task', 'isDone': false, 'priority': 1 }); this.selectObject(task); this.invokeLater(function () { var contentIndex = this.indexOf(task); var list = Sinatra.mainPage.getPath('mainPane.middleView.contentView') var listItem = list.itemViewForContentIndex(contentIndex); listItem.beginEditing(); }); return YES; and in the main: addButton: SC.ButtonView.design({ layout: { centerY: 0, height: 24, right: 12, width: 100 }, title: 'Add Task', target: 'Sinatra.tasksController', action: 'addTask' }), I can't see the problem, please help. (I have only tested this in firefox on kubuntu)

  • Javascript resizing with window.open and WebBrowser control

    - by Raj
    I'm using WPF WebBrowser control and handling NewWindow3 events using following code: IServiceProvider serviceProvider = (IServiceProvider)webBrowser.Document; Guid serviceGuid = SID_SWebBrowserApp; Guid iid = typeof(SHDocVw.WebBrowser).GUID; SHDocVw.WebBrowser wb = (SHDocVw.WebBrowser)serviceProvider.QueryService(ref serviceGuid, ref iid); wb.NewWindow3 += new SHDocVw.DWebBrowserEvents2_NewWindow3EventHandler(wb_NewWindow3); How to handle javascript resizing when navigating using window.open, something like this: window.open('Sample.htm',null,'height=200,width=400,status=yes,toolbar=no,menubar=no,location=no'); Is there anyway to get height and width requested by caller in NewWindow3 event handler?

  • Bloomberg APIv3 returning Slow Consumer Warnings!

    - by Marcus
    I made a program in c# based on the example "SubscriptionWithEventHandlerExample" of API 3.2.9.0. After subscribing to about 500 securities for realtime data, I receive some ADMIN event warnings claiming SlowConsumerWarning and SlowConsumerWarningCleared. I read somewhere that it introduces some delay, until I process all events. The problem is that in my code I only receive callbacks from bloomberg. The event queue isn´t even in my program! Some things that I tried: 1) raise the queue limit, setting MaxEventQueueSize in the session options (seems to have no effect) 2) see if I get any timeout event (no, I don't get any) 3) create multiple sessions and subscribing 50 securities in each (now I get multiple warnings, one for each thread) Is there something that I can do or this behavior is out of my scope?

  • jQuery Address changed event

    - by Dustin
    I'm trying my hand at jQuery Address http://www.asual.com/jquery/address/ On a click event I set $.address.value(mypath); This fires off the $.address.change() event. When I click a link I want the behavior to be slightly different than when this event is fired by clicking the back/forward button or with a bookmark or link. Is there a way to distinguish between the two events. I've looked at the event object passed to $.address.change() and they seem to be identical in both situations.

  • How to stop a WPF binding from ignoring the PropertyChanged event that it caused?

    - by Jacob Stanley
    I have a TextBox bound to a ViewModel's Text property with the following setup: Xaml <TextBox Text="{Binding Text}"/> C# public class ViewModel : INotifyPropertyChanged { public string Text { get { return m_Text; } set { if (String.Equals(m_Text, value)) { return; } m_Text = value.ToLower(); RaisePropertyChanged("Text"); } } // Snip } When I type some stuff in to the TextBox it successfully sets the Text property on the ViewModel. The problem is that WPF ignores the property changed event that is raised by it's own update. This results in the user not seeing the text they typed converted to lowercase. How can I change this behaviour so that the TextBox updates with lowercase text? Note: this is just an example I have used to illustrate the problem of WPF ignoring events. I'm not really interested in converting strings to lowercase or any issues with String.Equals(string, string).

  • Repeater ItemDataBound Complete Trigger

    - by OliverS
    Hi I have a Repeater and I am doing various things during the ItemDataBound event. My Repeater is in a control. What I am noticing is that the things that are supposed to happen in the ItemDataBound event happen after the Page_Load of the page hosting the control. Is there a way to use some sort of ItemDataBoundComplete trigger so I can do other things on my page after the events of the ItemDataBound have taken place? Thanks, please let me know if I have not been clear. [Edit] I have controls that are being bound to the ItemDataBound and they are not available until after the Page_Load for the page hosting the control. [Solution] (In my case): In my page I used the following: Control.Page.LoadComplete += new EventHandler(Control_LoadComplete); Then I performed what I had to do in that event.

  • JComponent undock effect

    - by Christo Du Preez
    I'm trying to accomplish an undock effect for a custom Swing JComponent. By default the component is used inside a form along with other components. I want to be able to maximize this component to use the whole screen and then be able to dock it again. So far I've tested public void showDialog() { JFrame mainFrame = App.getApplication().getMainFrame(); JDialog dialog = new JDialog(mainFrame); dialog.setModal(true); dialog.setSize(800, 600); //Set to 80x660 for now dialog.add(this); //This is my JComponent dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); dialog.setVisible(true); } This gives me desired effect but when closing the dialog my component doesn't receive events no more. How can I prevent this? Or is there perhaps a better way to accomplish this?

  • Create popup "toaster" notifications in Windows with .NET

    - by Draak
    I am using .NET and am creating a desktop app/service that will display notifications in the corner of my Desktop when certain events are triggered. I don't want to use a regular Message Box b/c that would be too intrusive. I want notifications to slide into view and then fade out after a few seconds. I am thinking of something that will act very much like the Outlook alerts that one gets when a new message arrives. The question is: Should I use WPF for this? I've never done anything with WPF but will happily try it if that's best means to the end. Is there a way to accomplish this with regular .NET libraries?

  • How to interpret trackpad pinch gestures to zoom IKImageBrowserView

    - by Fraser Speirs
    I have an IKImageBrowserView that I want to be able to pinch-zoom using a multi-touch trackpad on a recent Mac laptop. The Cocoa Event Handling Guide, in the section Handling Gesture Events says: The magnification accessor method returns a floating-point (CGFloat) value representing a factor of magnification ..and goes on to show code that adjusts the size of the view by multiplying height and width by magnification + 1.0. This doesn't seem to be the right approach for zooming IKImageBrowserView, whose zoomValue property is clamped between 0.0 and 1.0. So, does anyone know how to interpret the event in -[NSResponder magnifyWithEvent:] to zoom IKImageBrowserView?

  • How does the momentum/inertial scroll work with the Magic Mouse on NSScrollView?

    - by jbrennan
    When you scroll with the newer Apple Magic Mouse (at least on 10.6, I can't confirm any previous Mac OS) you get inertial scroll like scrolling on iPhone (that is, after a flick of the finger to scroll, it doesn't abruptly stop, but instead gradually slows down). This behaviour is "for free" with all NSScrollViews, it would appear. There are exceptional cases, such as Tweetie for Mac (I've heard Tweetie was written with a custom Table View class that works akin to how UITableView works on iPhone). My question is, how do the scroll views know how to do this inertial scrolling? My guess is the mouse [driver] repeatedly sends scroll events with a dampening scroll magnitude (or something like that) over the scroll period. But I'm not really sure how it works. I am having some scrolling problems in my scrollview class and I'm trying to figure out why (obviously we don't have the source code to Tweetie to see why it doesn't get the proper scrolling), but just trying to better understand how it works in order to fix my own problems.

  • Managing Unique IDs in stateless (web) DB4O applications

    - by Phil.Wheeler
    I'm playing around with building a new web application using DB4O - piles of fun and some really interesting stuff learned. The one thing I'm struggling with is DB4O's current lack of support for stateless applications (i.e. web apps, mostly) and the need for automatically-generated IDs. There are a number of creative and interesting approaches that I've been able to find that hook into DB4O's events, use GUIDs rather than numeric IDs or for whatever reason avoid using any system of ID at all. While each approach has its merits, I'm wondering if the less-elegant approach might equally be the best fit. Consider the following pseudo-code: If ID == 0 or null Set ID = (typeof(myObject)).Count myObject.Save It seems like such a blindingly simple approach, it's usually about here that I start thinking, "I've missed something really obvious". Have I?

  • Message pump in .NET Windows service

    - by Pickles
    I have a Windows Service written in C# that handles all of our external hardware I/O for a kiosk application. One of our new devices is a USB device that comes with an API in a native DLL. I have a proper P/Invoke wrapper class created. However, this API must be initialized with an HWnd to a windows application because it uses the message pump to raise asynchronous events. Besides putting in a request to the hardware manufacturer to provide us with an API that does not depend on a Windows message pump, is there any way to manually instantiate a message pump in a new thread in my Windows Service that I can pass into this API? Do I actually have to create a full Application class, or is there a lower level .NET class that encapsulates a message pump?

  • Grouping Windows Forms Radiobuttons with different parent controls in C#

    - by Jerry
    Hi, I've got a Windows Forms application in which I have a number of RadioButtons. These RadioButtons are placed within a FlowLayoutPanel which automatically arranges them for me. All RadioButtons that are directly added to the FlowLayoutPanel are grouped, meaning I can select only one of them. However, some of these RadioButtons are paired up with a TextBox so I can supply some argument there. But to have all this arranged properly, I add a Panel control to the FlowLayoutPanel so I can control the alignment of the RadioButton and TextBox relatively to each other myself. These RadioButtons now have their own respective Panels as parent controls and thus are no longer included in the radio group with the other RadioButtons. I read that the the RadioButtons that are in the System.Web.UI namespace have a GroupName property, but unfortunately their System.Windows.Forms counterparts lack this property. Is there some other way I can group these radio buttons are am I going to have to handle onClick events myself? Thanks, Jerry

  • Problems with CGPoint in touches event

    - by Jason
    I'm having some problems with storing variables from my touch events. The warning I get when I run this is that coord and icoord are unused, but I used them in the viewDidLoad implementation, is there a reason why this does not work? Any suggestions? -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint icoord = [touch locationInView:touch.view]; } -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint coord = [touch locationInView:touch.view]; } - (void)viewDidLoad { if (coord.x > icoord.x) { player.center = CGPointMake(player.center.x + 5, player.center.y); } } Thanks.

  • How to render a Partial from a Model in Rails 2.3.5

    - by empire29
    I have a Rails 2.3.5 application and Im trying to render several Partials from within a Model (i know, i know -- im not supposed to). The reason im doing this is im integrating a Comet server (APE) into my Rails app and need to push updates out based on the Model's events (ex. after_create). I have tried doing this: ActionView::Base.new(Rails::Configuration.new.view_path).render(:partial => "pages/show", :locals => {:page => self}) Which allows me to render simple partials that don't user helpers, however if I try to user a link_to in my partial, i receive an error stating: undefined method `url_for' for nil:NilClass I've made sure that the object being passed into the "project_path(project)" is not nil. I've also tried including: include ActionView::Helpers::UrlHelper include ActionController::UrlWriter in the Module that contains the method that makes the above "render" call. Does anyone know how to work around this? Thanks

  • jQuery drag drop slower for more DIV items

    Hi there, I have got a hierarchichal tags (with parent child relationship) in my page and it will account to 500 - 4500 (can even grow). When i bound the draggable and droppable for all i saw very bad performance in IE7 and IE6. The custom helper wont move smoothly and was very very slow. Based on some other post i have made the droppable been bound/unbound on mouseover and mouseout events (dynamically). Its better now. But still i dont see the custom helper move very smoothly there is a gap between the mouse cursor and the helper when they move and gets very bad when i access the site from remote. Please help me to address this performance issue. Am totally stuck here.. :(

  • How to establish a two-way communication between Activity and Service in different process?

    - by steff
    Hi everyone, I'm working on establishing a two-way communication between an Activity and a Service which runs in a different process. Querying the process from the Activity is no big deal. But I want the process to notify the Activity on events. The idea behind it is this: the service runs independently from the actual app. It queries a webserver periodically. If a new task is found on the webserver the process should notify the activity. I found this thread over at AndDev.org but it doesn't seem to work for me. I've been messing around with BroadcastReceiver. I've implemented an interface which should notify the Activity but the problem is that the listener is always null since the Broadcast from the process is done via Intent, hence the class that extends BroadcastReceiver will be newly instantiated. How can I establish a 2-way communication? This has to be possible. Thanks for any help, steff

  • Tap, Pan for a map & fixed headers - event conflict

    - by kaiser
    I'm currently developing a small WebApp that makes use of Google Maps (front-end uses jquery-ui-maps) jQuery Mobile with a fixed header & footer Now I encountered a conflict that appears on touch enabled devices as well as on desktop/mouse controlled "click" events: When I "tap" or "click" the map to actually "pan" it, then my header/footer toggles it's visibility. As I want to keep the toggle behaviour, I can't simply deactivate it, but showing/hiding the header/footer on every "pan" of the map is odd. After thinking some time about it, I think I got a concept that should work: Question: How I can I add a delay to the visibility toggle for the header/footer? So when I don't release the finger/mouse after XYms, the header/footer doesn't show/hide? Example: jQuery( '#map_page' ).live( "pageinit" ,function() { // Att.: pseudo code if ( $.mobile.taphold ) don't toggle fixed if ( mousedown > XYms ) don't toggle fixed } ); Thanks!

  • DataGridView lags for a second with large data updates

    - by alexD
    I have a DataGridView with about 400 rows and 10 columns. When the user first displays this table, it receives all of the data from the server and populates the table. The DGV uses a DataTable as it's data source, and when updating the DataTable I use row.BeginEdit/EndEdit and acceptChanges, but when the View itself is updated it lags for a second while all of the DGV is being updated. I am wondering if there is a way to make this smooth, so that for example, if the user is scrolling through the data and it updates, it won't interrupt the scrolling. Or if the user is moving the display around the screen and it updates, it won't interrupt. Is there an easy way to do this? If not, is there away to prevent the DGV from updating the view until all events have ended so it won't be repainted until the user stops scrolling, dragging, etc ?

  • How to filter Backbone.js Collection and Rerender App View?

    - by Jeremy H.
    Is is a total Backbone.js noob question. I am working off of the ToDo Backbone.js example trying to build out a fairly simple single app interface. While the todo project is more about user input, this app is more about filtering the data based on the user options (click events). I am completely new to Backbone.js and Mongoose and have been unable to find a good example of what I am trying to do. I have been able to get my api to pull the data from the MongoDB collection and drop it into the Backbone.js collection which renders it in the app. What I cannot for the life of me figure out how to do is filter that data and re-render the app view. I am trying to filter by the "type" field in the document. Here is my script: (I am totally aware of some major refactoring needed, I am just rapid prototyping a concept.) $(function() { window.Job = Backbone.Model.extend({ idAttribute: "_id", defaults: function() { return { attachments: false } } }); window.JobsList = Backbone.Collection.extend({ model: Job, url: '/api/jobs', leads: function() { return this.filter(function(job){ return job.get('type') == "Lead"; }); } }); window.Jobs = new JobsList; window.JobView = Backbone.View.extend({ tagName: "div", className: "item", template: _.template($('#item-template').html()), initialize: function() { this.model.bind('change', this.render, this); this.model.bind('destroy', this.remove, this); }, render: function() { $(this.el).html(this.template(this.model.toJSON())); this.setText(); return this; }, setText: function() { var month=new Array(); month[0]="Jan"; month[1]="Feb"; month[2]="Mar"; month[3]="Apr"; month[4]="May"; month[5]="Jun"; month[6]="Jul"; month[7]="Aug"; month[8]="Sep"; month[9]="Oct"; month[10]="Nov"; month[11]="Dec"; var title = this.model.get('title'); var description = this.model.get('description'); var datemonth = this.model.get('datem'); var dateday = this.model.get('dated'); var jobtype = this.model.get('type'); var jobstatus = this.model.get('status'); var amount = this.model.get('amount'); var paymentstatus = this.model.get('paymentstatus') var type = this.$('.status .jobtype'); var status = this.$('.status .jobstatus'); this.$('.title a').text(title); this.$('.description').text(description); this.$('.date .month').text(month[datemonth]); this.$('.date .day').text(dateday); type.text(jobtype); status.text(jobstatus); if(amount > 0) this.$('.paymentamount').text(amount) if(paymentstatus) this.$('.paymentstatus').text(paymentstatus) if(jobstatus === 'New') { status.addClass('new'); } else if (jobstatus === 'Past Due') { status.addClass('pastdue') }; if(jobtype === 'Lead') { type.addClass('lead'); } else if (jobtype === '') { type.addClass(''); }; }, remove: function() { $(this.el).remove(); }, clear: function() { this.model.destroy(); } }); window.AppView = Backbone.View.extend({ el: $("#main"), events: { "click #leads .highlight" : "filterLeads" }, initialize: function() { Jobs.bind('add', this.addOne, this); Jobs.bind('reset', this.addAll, this); Jobs.bind('all', this.render, this); Jobs.fetch(); }, addOne: function(job) { var view = new JobView({model: job}); this.$("#activitystream").append(view.render().el); }, addAll: function() { Jobs.each(this.addOne); }, filterLeads: function() { // left here, this event fires but i need to figure out how to filter the activity list. } }); window.App = new AppView; });

  • Why does asp.net mvc form submits itself on button clicks when javascript function error?

    - by melaos
    hi guys, i'm new to the asp.net mvc, and while working on this, i used very basic asp.net mvc stuff like beginform, etc. i used a lot of jquery codes this round for client side validation, ajax data retrieval, and other gui works. and i used a combinations of html inputs buttons, etc and the asp.net mvc type of controls. what i noticed is that whenever i click on a button control, which sometimes are tied to either jquery oclick events, when there's a javascript error, the page will just go on and submit. why is this happening and what am i missing here? my bad for the dumb questions.. thanks

  • Strategy for unsubscribing event handlers

    - by stiank81
    In my WPF application I have a View that is given a ViewModel, and when given this View it adds event handlers to the ViewModel's PropertyChanged event. When some action occur in the GUI I remove the View and add another View to the holding container - where this new one is bound to the same ViewModel. After this has happened the old View still keeps handling PropertyChanged events in the ViewModel. I'm assuming this happens because the View hasn't been collected by the Garbage Collector yet, and therefore is alive? Well - I need it to stop. My assumption is that I need to manually detach the event handler from the ViewModel? Is there a best-practice on how to handle this?

  • how to lengthen the pause between the words with text-to-speech (pyTTS or SAPI5)

    - by Berry Tsakala
    Is it possible to extend the gap between spoken words when using text to speech with SAPI5 ? The problem is that esp. with some voices, the words are almost connected to each other, which makes the speech more difficult to understand. I'm using python and pyTTS module (on windows, since it's using SAPI) I tried to hook to the OnWord event and add a time.sleep() or tts.Pause(), but apparently even though all the events are caught, they are being processed only at the end of the spoken text, whether i'm using the sync or async flag. In this NON WORKING example, the sleep() method is executed only after the sentence is spoken: tts = pyTTS.Create() def f(x): tts.Pause() sleep(0.5) tts.Resume() tts.OnWord = f tts.Speak(text)
