  • UISlider returns two Touch Up Inside events, why does that happen?

    - by willc2
    I have a slider that I'm using to set a float value somewhere. I connect Value Changed to a method in my viewController. That part works fine. I need to know when the user starts touching the control but not necessarily every single instant that the slider changes (I receive the Value Changed events for that). So I connected a Touch Up Inside event to another method in the viewController. The problem it, that method gets called twice when the user touches the UISlider control. WTF? It doesn't work that way with UIButtons or other touch events like Touch Down. I can work around it, I think, but it seems like a bug in the way the slider control handles touches. Does anybody know why it happens? BTW: the double touch event happens even when Touch Up Inside is the only connected event.

  • Working with DataBinding and Page_Load in ASP.NET MVP

    - by Joel
    I'm using WebForms MVP to create some simple reporting applications. Most of these applications consist of a few search criteria inputs and a ComponentArt datagrid that I'm populating with data from the database. Most of the markup is in a UserControl, which is in a content page with a master page. My problem is that the control's Page_Load event is firing before the control events that caused the postback in the first place. Basically, the user clicks the search button, and Page_Load is fired BEFORE Search_Click. This is messing with the databinding scheme I've been using. So that's the question: Why is my Page_Load event firing before the event handler, and what can I do about it? I don't THINK this problem is related to WebForms MVP or ComponentArt, but obviously I could be wrong. Thanks.

  • coin rotation, as3

    - by VideoDnd
    What's the best way to make a coin rotation? I tried Math.random, but the coin doesn't wobble correctly. starter code //ROTATION addEventListener(Event.ENTER_FRAME, enterFrameHandler); function enterFrameHandler(event:Event):void { /* ADD VELOCITY, GRAVITY, ACCELERATION */ coin.rotationY += 8; } tried this, but it has no gravity or accelleration //ROTATION AND RANDOM MATH function wobble():void { var wobble = ((Math.random()*4)-2); flk.rotationY -= 11+wobble/2; flk.rotationX -= 2+wobble/20; } var myInterval:uint = setInterval (wobble, 40); I took out the work physics from my title:) I want it to behave like its affected by velocity, gravity, and acceleration.

  • SoundChannel object plays small portion after being stopped and played again

    - by gok
    SoundChannel object is stopped and played again. When played again it plays small portion from the previous position and suddenly jumps back to the beginning. It doesn't play the whole sound before looping. This happens only once, then it loops normally. It happens again if I stop and play. public function play():void { channel = clip.play(trimIn); volume(currentVolume); isPlaying = true; timer.start(); channel.addEventListener(Event.SOUND_COMPLETE, loopMusic); } public function loopMusic(e:Event=null):void { if (channel != null) { timer.stop(); channel.removeEventListener(Event.SOUND_COMPLETE, loopMusic); play(); } } Do I need to somehow reset the soundChannel?

  • Tracking finger move in order to rotate a triangle : tracking is not perfect

    - by Laurent BERNABE
    I've written a custom view, with the OpenGL_1 technology, in order to let user rotate a red triangle just by dragging it along x axis. (Will give a rotation around Y axis). It works, but there is a bit of latency when dragging from one direction to the other (without releasing the mouse/finger). So it seems that my code is not yet "goal perfect". (I am convinced that no code is perfect in itself). I thought of using a quaternion, but maybe it won't be so usefull : must I really use a Quaternion (or a kind of Matrix) ? I've designed application for Android 4.0.3, but it could fit into Android api 3 (Android 1.5) as well (at least, I think it could). So here is my main layout : activity_main.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <com.laurent_bernabe.android.triangletournant3d.MyOpenGLView android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout> Here is my main activity : MainActivity.java package com.laurent_bernabe.android.triangletournant3d; import android.app.Activity; import android.os.Bundle; import android.support.v4.app.NavUtils; import android.view.Menu; import android.view.MenuItem; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: NavUtils.navigateUpFromSameTask(this); return true; } return super.onOptionsItemSelected(item); } } And finally, my OpenGL view MyOpenGLView.java package com.laurent_bernabe.android.triangletournant3d; import java.nio.ByteBuffer; import java.nio.ByteOrder; import java.nio.FloatBuffer; import javax.microedition.khronos.egl.EGLConfig; import javax.microedition.khronos.opengles.GL10; import android.content.Context; import android.graphics.Point; import android.opengl.GLSurfaceView; import android.opengl.GLSurfaceView.Renderer; import android.opengl.GLU; import android.util.AttributeSet; import android.view.MotionEvent; public class MyOpenGLView extends GLSurfaceView implements Renderer { public MyOpenGLView(Context context, AttributeSet attrs) { super(context, attrs); setRenderer(this); } public MyOpenGLView(Context context) { this(context, null); } @Override public boolean onTouchEvent(MotionEvent event) { int actionMasked = event.getActionMasked(); switch(actionMasked){ case MotionEvent.ACTION_DOWN: savedClickLocation = new Point((int) event.getX(), (int) event.getY()); break; case MotionEvent.ACTION_UP: savedClickLocation = null; break; case MotionEvent.ACTION_MOVE: Point newClickLocation = new Point((int) event.getX(), (int) event.getY()); int dx = newClickLocation.x - savedClickLocation.x; angle += Math.toRadians(dx); break; } return true; } @Override public void onDrawFrame(GL10 gl) { gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); gl.glLoadIdentity(); GLU.gluLookAt(gl, 0f, 0f, 5f, 0f, 0f, 0f, 0f, 1f, 0f ); gl.glRotatef(angle, 0f, 1f, 0f); gl.glColor4f(1f, 0f, 0f, 0f); gl.glVertexPointer(2, GL10.GL_FLOAT, 0, triangleCoordsBuff); gl.glDrawArrays(GL10.GL_TRIANGLES, 0, 3); } @Override public void onSurfaceChanged(GL10 gl, int width, int height) { gl.glViewport(0, 0, width, height); gl.glMatrixMode(GL10.GL_PROJECTION); gl.glLoadIdentity(); GLU.gluPerspective(gl, 60f, (float) width / height, 0.1f, 10f); gl.glMatrixMode(GL10.GL_MODELVIEW); } @Override public void onSurfaceCreated(GL10 gl, EGLConfig config) { gl.glEnable(GL10.GL_DEPTH_TEST); gl.glClearDepthf(1.0f); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); buildTriangleCoordsBuffer(); } private void buildTriangleCoordsBuffer() { ByteBuffer buffer = ByteBuffer.allocateDirect(4*triangleCoords.length); buffer.order(ByteOrder.nativeOrder()); triangleCoordsBuff = buffer.asFloatBuffer(); triangleCoordsBuff.put(triangleCoords); triangleCoordsBuff.rewind(); } private float [] triangleCoords = {-1f, -1f, +1f, -1f, +1f, +1f}; private FloatBuffer triangleCoordsBuff; private float angle = 0f; private Point savedClickLocation; } I don't think I really have to give you my manifest file. But I can if you think it is necessary. I've just tested on Emulator, not on real device. So, how can improve the reactivity ? Thanks in advance.

  • zoom_changed only triggers once in google maps api version 3 using MVC

    - by fredrik
    Hi, I'm trying to use the MVC objects in google maps version 3. What I can't seem to figure out is why my zoom_changed method is only invoked once. When I first load the map the zoom_changed method is invoked. But not when I zoom on the map. function MarkerWidget (options) { this.setValues(options); this.set('zoom', this.map.zoom); var marker = new google.maps.Marker({ icon : this.icon, mouseOverIcon : this.mouseOverIcon, orgIcon : this.orgIcon }); marker.bindTo('map', this); marker.bindTo('position', this); google.maps.event.addListener(marker, 'mouseover', this.onmouseover); google.maps.event.addListener(marker, 'mouseout', this.onmouseout); } MarkerWidget.prototype = new google.maps.MVCObject(); MarkerWidget.prototype.zoom_changed = function () { $.log(this, new Date()); } Shouldn't the map object fire the zoom event and notify all object's that has "this.set('zoom', this.map.zoom)" ? ..fredrik

  • Cleanup for control inside a FlowDocument

    - by Thorarin
    I have a custom control that I use inside a FlowDocument. The control uses a System.Drawing.ImageAnimator to display transparent, animated GIF images. Why is this such a pain in the butt in WPF anyway? :P In my original implementation, this was causing memory leaks when a paragraph containing the control was being deleted from the document, because the ImageAnimator kept a reference to the control for event handling. I've now implemented a WeakEventManager pattern which seems to indeed fix the leak itself, but I would like to stop "OnFrameChanged" events from being fired if a particular animated GIF is not currently in the document, instead of relying on the garbage collector to eventually collect the control objects and my event manager to notice that there no longer are valid listeners to the event. Basically, I would like to take a more active role in this and have the control react to being removed from the FlowDocument. Is there some way to do this? I've been unable to find it. OnVisualParentChanged doesn't get fired, because the direct parent (a Paragraph) is unchanged.

  • jQuery: Highlight element under mouse cursor?

    - by Ralph
    I'm trying to create an "element picker" in jQuery, like Firebug has. Basically, I want to highlight the element underneath the user's mouse. Here's what I've got so far, but it isn't working very well: $('*').mouseover(function (event) { var $this = $(this); $div.offset($this.offset()).width($this.width()).height($this.height()); return false; }); var $div = $('<div>') .css({ 'background-color': 'rgba(255,0,0,.5)', 'position': 'absolute', 'z-index': '65535' }) .appendTo('body'); Basically, I'm injecting a div into the DOM that has a semi-transparent background. Then I listen for the mouseover event on every element, then move the div so that it covers that element. Right now, this just makes the whole page go red as soon as you move your mouse over the page. How can I get this to work nicer? Edit: Pretty sure the problem is that as soon as my mouse touches the page, the body gets selected, and then as I move my mouse around, none of the moments get passed through the highligher because its overtop of everything. Firebug Digging through Firebug source code, I found this: drawBoxModel: function(el) { // avoid error when the element is not attached a document if (!el || !el.parentNode) return; var box = Firebug.browser.getElementBox(el); var windowSize = Firebug.browser.getWindowSize(); var scrollPosition = Firebug.browser.getWindowScrollPosition(); // element may be occluded by the chrome, when in frame mode var offsetHeight = Firebug.chrome.type == "frame" ? FirebugChrome.height : 0; // if element box is not inside the viewport, don't draw the box model if (box.top > scrollPosition.top + windowSize.height - offsetHeight || box.left > scrollPosition.left + windowSize.width || scrollPosition.top > box.top + box.height || scrollPosition.left > box.left + box.width ) return; var top = box.top; var left = box.left; var height = box.height; var width = box.width; var margin = Firebug.browser.getMeasurementBox(el, "margin"); var padding = Firebug.browser.getMeasurementBox(el, "padding"); var border = Firebug.browser.getMeasurementBox(el, "border"); boxModelStyle.top = top - margin.top + "px"; boxModelStyle.left = left - margin.left + "px"; boxModelStyle.height = height + margin.top + margin.bottom + "px"; boxModelStyle.width = width + margin.left + margin.right + "px"; boxBorderStyle.top = margin.top + "px"; boxBorderStyle.left = margin.left + "px"; boxBorderStyle.height = height + "px"; boxBorderStyle.width = width + "px"; boxPaddingStyle.top = margin.top + border.top + "px"; boxPaddingStyle.left = margin.left + border.left + "px"; boxPaddingStyle.height = height - border.top - border.bottom + "px"; boxPaddingStyle.width = width - border.left - border.right + "px"; boxContentStyle.top = margin.top + border.top + padding.top + "px"; boxContentStyle.left = margin.left + border.left + padding.left + "px"; boxContentStyle.height = height - border.top - padding.top - padding.bottom - border.bottom + "px"; boxContentStyle.width = width - border.left - padding.left - padding.right - border.right + "px"; if (!boxModelVisible) this.showBoxModel(); }, hideBoxModel: function() { if (!boxModelVisible) return; offlineFragment.appendChild(boxModel); boxModelVisible = false; }, showBoxModel: function() { if (boxModelVisible) return; if (outlineVisible) this.hideOutline(); Firebug.browser.document.getElementsByTagName("body")[0].appendChild(boxModel); boxModelVisible = true; } Looks like they're using a standard div + css to draw it..... just have to figure out how they're handling the events now... (this file is 28K lines long) There's also this snippet, which I guess retrieves the appropriate object.... although I can't figure out how. They're looking for a class "objectLink-element"... and I have no idea what this "repObject" is. onMouseMove: function(event) { var target = event.srcElement || event.target; var object = getAncestorByClass(target, "objectLink-element"); object = object ? object.repObject : null; if(object && instanceOf(object, "Element") && object.nodeType == 1) { if(object != lastHighlightedObject) { Firebug.Inspector.drawBoxModel(object); object = lastHighlightedObject; } } else Firebug.Inspector.hideBoxModel(); }, I'm thinking that maybe when the mousemove or mouseover event fires for the highlighter node I can somehow pass it along instead? Maybe to node it's covering...?

    Hi, I have an xml file the content which i have to write to a Database table using ssis pacakge. I am using xml source nad oledb destination My issue now is this xml file generate multiple outputs .(event,produt,offer,form) etc. But i need to write all in one data row(more than one if 2 products are there for the event) in the database. But i do not know how to use this multiple outputs and make a single row for a event. I hav read numerous articles about this subject but not able to take a decision.what is the right way of doing this. 1) xml source ? (if i use this how do i merge the multiple outputs) 2) or a script task using xml objects read and write to the DB. or anything new ? Please provide me some solutions xml sample file * - ABc. 2009-06-07 2010-04-30 region test 1 contact - offertest product1 product1 187 * Thanks SNA

  • jQuery AJAX not redirecting?

    - by MidnightLightning
    I have a simple PHP page (for testing) that simply calls header("Location: http://www.example.com");exit;, which resides on the same server, in the same directory as another file with the following jQuery Javascript: $(document).ready(function() { jQuery.ajax({ type : 'GET', url : 'bounce.php', error : function(xhr, status, error) { console.log("ERROR: ", xhr, xhr.status, xhr.getAllResponseHeaders()); }, complete : function(xhr, status) { // Get headers of the response console.log("COMPLETE: ", xhr, xhr.status, xhr.getAllResponseHeaders()); } }); }); I was expecting (from several other StackOverflow responses) for the xhr.status to return "302", but instead the AJAX call is triggering the "error" event (and then the "complete" event), and xhr.status is returning 0 (zero), and .getAllResponseHeaders() is coming back null (in both the error, and complete functions). Firebug is showing the "302 Moved Temporarily", and the response headers. So why is this triggering the error event, and not passing along the proper 302 code, and headers? Is this something to do with the Same Origin since the bouncing script and the fetching script are both on the same server? Is this jQuery or Javascript's fault?

  • 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?

  • drawing above gtkentry using cairo

    - by Durgesh
    Hi Experts, I want to use cairo to enhance gtkentry look. For this, I have connected a callback to 'expose-event'. In callback, I call gtkentry's original expose-event handler. After that, I create cairo context and draw some lines and destroy the cairo. I return 'TRUE' as return value of callback function so that expose-event does not propagate. Now my problem is, I am drawing line from (0,0) to (100,100). But line appears only over the border areas of the gtkentry. The place where text is, it does not appear. Please help. Kind Regards -Durgesh O Mishra

  • accessing associations within GORM Events

    - by Don
    Hi, My Grails app has a User class and a Role class. The User class has an authorities property which holds the roles assigned to that user, e.g. class User { static hasMany = [authorities: Role] // This method is called automatically after a user is inserted def afterInsert() { this.authorities.size() } } If I create a user and assign them a role, a NullPointerException is thrown from the GORM event method afterInsert(), because authorities is null. If I comment out afterInsert() the user is saved correctly along with the assigned role. Is there some reason why I can't access associations from GORM event methods. Is is possible that this event is fired after the User row is inserted, but before the row is added to the User-Role join table? Thanks, Don

  • How does rolling back an application level transaction interact with SqlDataAdapter events in ADO.NE

    - by ilasno
    When utilizing the RowUpdated event in the SqlAdapter class, i'm assuming that it is raised directly following the return of the database interaction that executes the update. If that update is part of an application level transaction (utilizing the SqlTransaction class) which is then rolled back, does this affect or interact at all with the RowUpdated event? Or is the RowUpdated event not raised until after the transaction is committed (this seems unlikely, but i couldn't find documentation)? If RowUpdated has already been raised, and then the transaction is rolled back, any good ideas on how to adjust something that may have been done in RowUpdated that should then, also be rolled back?

  • AcceptButton for each group of controls in different tabs, Can't use some envents in Combobox to mak

    - by Muhammad Kashif Nadeem
    I have different tabs on my UserControl. Each tab has some controls and button. I want to change AcceptButton on the basis of group of controls I am in. I can use TextChanged event or Enter event to make a button AcceptButton for Textboxes but I have some Comboboxes too. These combos are auto complete so I can't user Enter event on these, because on Enter these combos should be completed. Following image can explain my problem more. Thanks.

  • jQuery hover function

    - by Daniel Hertz
    So I have a hover function that is supposed to move an arrow under the corrent the link that someone hovers over. The problem is, the arrow never returns to the current link when the person stops hovering over the link. However, if I set the left properly with a constant value it works. Anyone have any ideas? var currentId = '#' + $('body').attr('id') + '_link'; var xCordCurrent = $(currentId).offset().left - ($('#arrow').width() / 2); var xCordHover = $(event.target).offset().left + ($(event.target).width() / 2) - ($('#arrow').width() / 2); $('#arrow').animate( { left: xCordHover }, { duration: 'slow', easing: 'easeOutBack' }) }, function(event) { $('#arrow').animate( { left: xCordCurrent }, { duration: 'slow', easing: 'easeOutBack' }) });

  • How do I check if a user is authenticated with NickServ using POE::Component::IRC::State in Perl?

    - by Troy
    I'm trying to test whether a user is registered on FreeNode. nick_info() doesn't seem to return information about this, so I want to use $irc-yield(whois = $nick); and then grab the irc_whois event's reply. The problem is that I want to wait until this event is fired, so I created a global variable $whois_result and wrote a sub like this: sub whois { my $nick = $_[0]; $whois_result = 0; $irc->yield(whois => $nick); while($whois_result == 0) { } return $whois_result; } with the irc_whois handler looking like: sub on_whois { $whois_result = $_[ARG0]; print "DEBUG: irc_whois fired.\n"; } Unfortunately, the event can't fire while the loop is running so this hangs. I'm sure there's a better way to do this, but I'm not familiar enough with this kind of programming to know. Any help would be greatly appreciated.

  • BackgroundWorker vs background Thread

    - by freddy smith
    I have a stylistic question about the choice of background thread implementation I should use on a windows form app. Currently I have a BackgroundWorker on a form that has an infinite (while(true)) loop. In this loop I use WaitHandle.WaitAny to keep the thread snoozing until something of interest happens. One of the event handles I wait on is a "stopthread" event so that I can break out of the loop. This event is signaled when from my overridden Form.Dispose(). I read somewhere that BackgroundWorker is really intended for operations that you dont want to tie up the UI with and have an finite end - like downloading a file, or processing a sequence of items. In this case the "end" is unknown and only when the window is closed. Therefore would it be more appropriate for me to use a background Thread instead of BackgroundWorker for this purpose?

  • Help with a Join in Rails 3

    - by Adam Albrecht
    I have the following models: class Event < ActiveRecord::Base has_many :action_items end class ActionItem < ActiveRecord::Base belongs_to :event belongs_to :action_item_type end class ActionItemType < ActiveRecord::Base has_many :action_items end And what I want to do is, for a given event, find all the action items that have an action item type with a name of "foo" (for example). So I think the SQL would go something like this: SELECT * FROM action_items a INNER JOIN action_item_types t ON a.action_item_type_id = t.id WHERE a.event_id = 1 AND t.name = "foo" Can anybody help me translate this into a nice active record query? (Rails 3 - Arel) Thanks!

  • Flash AS3 - Display an error if the XML if incorrect

    - by ongoingworlds
    Hi, I'm creating a flash application which loads in some XML which is generated dynamically from the CMS. I want to display an error in case the XML file isn't formatted correctly. When I test this with incorrectly formatted XML, it will just get to the line myXML = XML(myLoader.data); and then just bomb out. How can I catch the error, display a message to the user, but the flash program to continue as normal. var myXMLURL:URLRequest = new URLRequest(XMLfile); var myLoader:URLLoader = new URLLoader(myXMLURL); myLoader.addEventListener(Event.COMPLETE, xmlLoaded); myLoader.addEventListener(IOErrorEvent.IO_ERROR, xmlFailed); var myXML:XML; //--when the xml is loaded, do this function xmlLoaded(e:Event):void { myXML = XML(myLoader.data); trace("XML = "+myXML); } //--if the xml fails to load, do this function xmlFailed(event:IOErrorEvent):void { errorMsg.text = "The XML file cannot be found" }
