• How do I query through a many-to-many relationship using NHibernate Criteria and Lambda Extensions?

  - by Brian Kendig

  In my database I have a Person table and an Event table (parties, meetings, &c.). This many-to-many relationship is represented through an Invitation table. Each Person can have many Invitations. Each Event can also have many Invitations. If I want a list of Events to which a Person is invited, I can use this HQL query: IQuery query = Session.CreateQuery("SELECT i.Event from Invitation i where i.Person = :p"); query.SetParameter("p", person); return query.List<Person>(); How would I write this query with NHibernate criteria and Lambda Extensions?

• Select next element of a given class

  - by kevinb92

  Hello, I want to hide and show some form in my page. For each form theres a link, and i want that, when i click on this link, it hide and show the nearest form of the link. My code looks like this : $$('.flagLink').each(function(s){ $(s).observe('click', function(event) { // here i want to hide and show the nearest form }); }); I've tried this : $$('.flagLink').each(function(s){ $(s).observe('click', function(event) { $(s).next('form').toggle(); }); }); It works but, i would like to be more precise like : $$('.flagLink').each(function(s){ $(s).observe('click', function(event) { $(s).next('.flagForm').toggle(); }); }); but the .flagForm selector doesnt work.

• How to capture the value change of numericUpDown ctrl real-time in .NET?

  - by Carlos_Liu

  I have implement the ValueChanged event, but I found it will be triggered only after change the focus from numericUpDown to other control or by clicking the up/down arrow. Inputting the value in the control will not trigger ValueChanged event. What I did now is adding an KeyDown event and judge if the input value is numeric (can not include SHIFT/CTRL/ALT key); but there is another case need to be involved: the user can paste value into the numericUpDown ctrl What I need is : When I was typing numeric value (only numeric) in the numericUpDown ctrl, it will known the content has been changed; When pasted a numeric value into the ctrl, it also kowns the content changed

• Manage multiple Jlabel's events

  - by IMAnis_tn

  I have a left Panel with multiples Jlabels which i use them as buttons to change a Main Panel's content which is layouted with a CardLayout. I cant work perfectly with these events: mouseEntered : to make highlight effect to the jlabel mouseExited : to take off the highlight effect. mouseClicked : to change the content of the main Panel and start some threads The problem here that can't found an event or a method tell me that another Jlabel has been clicked so i can stop my threads started in the mouseClicked event, OR an event or method tell me that a JPanel in the CardLayout has been displayed or hidden.

• Unexpected cross threading issue

  - by haughtonomous

  I'm trying to do something very simple in principal, but I keep getting a cross-threading exception which has me stumped because I'm not setting out to use multiple threads. I have a Windows Forms application. It launches another Windows Forms application (using the System.Diagnostics.Process class) , and catches the Exited event when that application is closed. My application event handler then tries to copy text from the clipboard to a control on the current displayed form. At this point a Cross-threading exception is thrown. I assume that the problem is that the event from the closing application is in another thread (I'm outside my comfort zone here, so bear with me), so the question boils down to "How do I prevent this exception?" I'm somewhat constrained into having to copy from the clipboard, but I could launch the other application a different way if that would solve the problem.

• jQuery UI Element vs Dojo (Dijit) Form Element

  - by Muers

  Dojo seems to have a useful feature in that it can setup event handlers and default options, etc for Dijit.form elements as it is inserting it into the DOM. For example, Dojo: var slider = new dijit.form.HorizontalSlider({ name: sliderContainerId+'_slider', value: sliderValue, minimum: sliderMax, maximum: sliderMin, onChange: function(value){ // some event handling logic } }, sliderContainerId); However, the jQuery UI Slider traditionally is applied to DOM elements that already exist: $( sliderContainerId ).slider({ value:100, min: 0, max: 500, step: 50, slide: function( event, ui ) { $( "#amount" ).val( "$" + ui.value ); } }); I need to be able to 'programmatically' create new Sliders (and other form elements), but I'm not sure how that could be achieved with the way jQuery is structured? Maybe I'm missing something obvious here.... MTIA

• C# : Redirect console application output : How to flush the output?

  - by user93422

  I am spawning external console application and use async output redirect. as shown in this SO post My problem is it seems that the spawned process needs to produce certain amount of output before I get the OutputDataReceived event notification. I want to receive the OutputDataReceived event as soon as possible. I have a bare-bones redirecting application, and here are some observations: 1. When I call a simple 'while(true) print("X");' console application (C#) I receive output event immediately. 2. When I call a 3d party app I am trying to wrap from the command line I see the line-by-line output. 3. When I call that 3d party app from my bare-bone wrapper (see 1) - the output comes in chunks (about one page size). What happens inside that app? FYI: The app in question is a "USBee DX Data Exctarctor (Async bus) v1.0".

• NHibernate auditing in disconnected mode

  - by Ciaran

  I'm developing an app with a Silverlight UI, transferring my domain objects over WCF and persisting them via NHibernate. I'm therefore working with NHibernate in a disconnected mode. I'm already using the NHibernate PreUpdate and PreInsert EventListeners to perform some metadata operations (updating Create/Update date, created/updated by etc) and they are working fine. I now have a requirement to perform data logging on some of my domain objects. So I will need to have an audit table that has a before-save and after-save state of certain entities. I had wanted to use the @event.Persister.OldState and @event.Persister.NewState to perform this logging, but because I am in a disconnected scenario (using different Sessions from when data is retrieved to when it is persisted), @event.Persister.OldState is null when I am saving my changes back to the database. How is anyone else doing data logging in a disconnected scenario with NHibernate?

• How to pass an asp.net control to a jQuery ajax call?

  - by Abe Miessler

  I have the following jQuery event that gets fired every time an anchor is clicked. How can I pass a asp.net control (lets say a textbox called "tb_name") as one of the parameters, in addition to the "target" parameter i'm already passing? <script type="text/javascript"> $(document).ready(function() { $("a").click(function(event) { $.ajax({ type: "POST", url: "Default.aspx/Click", data: "{target:'" + event.target + "'}", contentType: "application/json; charset=utf-8", dataType: "json", error: function(xhr, ajaxOptions, thrownError) { alert(xhr.responseText); $("#myContent").html(xhr.statusText); //alert(xhr.responseText); }, success: function(msg) { alert(msg.d); } }); return false; }) }) </script>

• Get list of running processes, get active process (and it's application) Flex/AIR

  - by Adam Kiss

  Hello, just a quickie (or maybe not:] ): Is it possible to get somehow list of running applications/processes and, while running in background, check which process is active? Additionally - if somehow, the answer was yes, is it possible to react for change of active window / application react just as if it was Event, or bind to it custom event (e.g. Event.SystemActiveAppChange)? Thank you for answers as well as pointers. EDIT: Due to probable missunderstanding, I mean local applications - on your win/mac/linux machine - I would like to (in process of learning of language) track what apps I use the most, make a little graph maybe? So, the point is: in AIR app, developed in FLEX, I would like to get/list all running applications/processes, as well as which one is active (on user's PC/Mac/Linux)

• Form authentication works on dev server but not on IIS

  - by Ilknur

  Hi, We have a similar problem. We have a web application running under default appdomain. It was working fine until a week before...Suddenly it has encountered a problem. Below message is taken from event logs. Event code: 4005 Event message: Forms authentication failed for the request. Reason: The ticket supplied has expired. Application uses FormsAuthentication and gets the roles from aspnetdb.. After the error, when user logins to the page, it does not redirects to the default.aspx. Again login.aspx comes up. On the other hand application works fine on development server(localhost), but not on www(IIS 6.0). Does any one has an idea? Thanks, Ilknur

• jQuery variables and scope

  - by Peuge

  I am writing a jQuery plugin and am running into a few problems with regard to variables. For example I have the following skeleton structure for my plugin, which is going to act on a textbox. In my init function I want to set a variable and bind a keypress event to my textbox. That keypress event needs to call another function, in which I need the variable. Is this possible? (function($){ var methods = { init : function(options){ return this.each(function(){ var $this = $(this); var someVar = 'somevar'; $this.keypress(function(event){ //I want to call my customFunction }); }); }, customFunction : function(){ //I am wanting to access 'someVar' here }; $.fn.mynamespace = function(method){ //handle which method to call here }; })(jQuery); Many thanks in advance.

• d3.behavior.zoom jitters, shakes, jumps, and bounces when dragging

  - by BrettonW

  I am using the d3.behavior.zoom to implement panning and zooming on a tree layout, but it is exhibiting a behavior I would describe as bouncing or numeric instability. When you start to drag, the display will inexplicably bounce left or right until it just disappears. The code looks like this: var svg = target.append ("g"); ... svg.call (d3.behavior.zoom() .translate ([0, 0]) .scale (1.0) .scaleExtent([0.5, 2.0]) .on("zoom", function() { svg.attr("transform","translate(" + d3.event.translate[0] + "," + d3.event.translate[1] + ") scale(" + d3.event.scale + ")"); }) ); Am I doing something wrong?

• python win32api registery key change

  Hi, I am trying to trigger an event every time a registry value is being modified. import win32api import win32event import win32con import _winreg key = _winreg.OpenKey(_winreg.HKEY_CURRENT_USER,'Control Panel\Desktop',0,_winreg.KEY_READ) sub_key = _winreg.CreateKey(key,'Wallpaper') evt = win32event.CreateEvent(None,0,0,None) win32api.RegNotifyChangeKeyValue(sub_key,1,win32api.REG_NOTIFY_CHANGE_ATTRIBUTES,evt,True) ret_code=win32event.WaitForSingleObject(evt,3000) if ret_code == win32con.WAIT_OBJECT_0: print "CHANGED" if ret_code == win32con.WAIT_TIMEOUT: print "TIMED" my problem is that this is never triggered , the event always time-out.

• Adding mouse events to dynamically loaded SWF

  - by Josamoto

  I am loading an external SWF using the Loader class, and adding it to the stage with addChild. When trying to add a mouse click event listener to the MovieClip, using addEventListener, nothing happens, the event never fires. Is there a specific way to add listeners to externally loaded movie clips? My code looks somewhat like this: var target:MovieClip = assets["screensaver"] as MovieClip; target.root.addEventListener(MouseEvent.CLICK, onClickScreenSaver, true); addChild(target); The target shows up on the display, but the CLICK event is completely ignored.

• Delegates vs. events in Cocoa

  - by aaronstacy

  I'm writing my first iPhone app, and I've been exploring the design patterns in Cocoa and Objective-C. I come from a background of client-side web development, so I'm trying to wrap my head around delegates. Specifically, I don't see why delegate objects are needed instead of event handlers. For instance, when the user presses a button, it is handled with an event (UITouchUpInside), but when the user finishes inputting to a text box and closes it with the 'Done' button, the action is handled by calling a method on the text box's delegate (textFieldShouldReturn). Why use a delegate method instead of an event? I also notice this in the view controller with the viewDidLoad method. Why not just use events?

• Cleanest Way to Invoke Cross-Thread Events

  - by Nick

  I find that the .NET event model is such that I'll often be raising an event on one thread and listening for it on another thread. I was wondering what the cleanest way to marshal an event from a background thread onto my UI thread is. Based on the community suggestions, I've used this: // earlier in the code mCoolObject.CoolEvent+= new CoolObjectEventHandler(mCoolObject_CoolEvent); // then private void mCoolObject_CoolEvent(object sender, CoolObjectEventArgs args) { if (InvokeRequired) { CoolObjectEventHandler cb = new CoolObjectEventHandler( mCoolObject_CoolEvent); Invoke(cb, new object[] { sender, args }); return; } // do the dirty work of my method here }

• jQuery mobile swipe spamming and animation

  - by halliewuud

  I have say 5 list items with images inside placed 200px from eachother. I am trying to animate these list items to slide horizontally left if one presses a link with the id = #next or if one swipes left. And vice versa for sliding the list items right. Every click or swipe results in a slide animation of 200px on every list item. I ran into a problem where spamming the #next or #prev button would cancel the current animation and start a new one. This results in list items not sliding 200px+200px+200... but something like this 200px+140px+120... This because like I said the animation is cut and therefore the sliding distance will be shorter. Now I solved this for the clicking event by disabling the button before the animation starts and then re'enabling it on the end callbak function. But this problem is remaining for the swipe event. How can I solve this problem for the swipe event?

• Error in vb.net windows service when connecting to SQL

  I've installed a vb.net windows service on a Windows 2008 machine, that is attempting to connect to SQL 2005. The service starts succesfully, but can't see the database. The event log has the following entry. The description for Event ID 0 from source SU4.ESMR.DAL.Job.FillPriorityJobByType(oJobDS, TypeID: 3 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. This was tested locally on both XP and 2008. All environments are 32 bit.

• Update NSView in function of events

  - by Forchita

  Hi everyone! I have a main view (subclass of NSView) and as i'm new to cocoa, i'd like to know how to update the view in function of events. I know there are many methods that take events such as -(void)mouseMoved:(NSEvent*)event or - (void)mouseClicked:(NSEvent*)event My algorithm to determine what to do is ready. I want to know where I should update the main view: is it in the -(void)mouseMoved:(NSEvent*)event or in the - (void)drawRect:(NSRect)dirtyRect. And if it is in drawRect, then how should i pass the information to it? Thanks in advance!
