  • C# Events and Lambdas, alternative to null check?

    - by Eugarps
    Does anybody see any drawbacks? It should be noted that you can't remove anonymous methods from an event delegate list, I'm aware of that (actually that was the conceptual motivation for this). The goal here is an alternative to: if (onFoo != null) onFoo.Invoke(this, null); And the code: public delegate void FooDelegate(object sender, EventArgs e); public class EventTest { public EventTest() { onFoo += (p,q) => { }; } public FireFoo() { onFoo.Invoke(this, null); } public event FooDelegate onFoo; }

  • gridview databind

    - by frenchie
    Hi, I'm doing a gridview with an object datasource: List<MyObject> TheSource = a linq query At some point, I have MyGridview.DataSource = TheSource; MyGridview.Databind(); and an OnRowDataBound event handler that's tied to the databinding. In that event handler, how do you make column 2 contain 2 objects from TheSource. For instance, in the TheSource, there is a variable for FirstName and another one for LastName. Column 2 needs to contain both the first and last name in the same cell. Thanks.

  • I need to add a KeyboardEvent to a movie clip in Flash cs4 AS 3.0

    - by psy-sci
    I have a movieclip called keyCButton that I want to add a keyboardEvent ("C" Key) to. This will play an animation from frames 2-30 with a sound. I have watched a few tutorials but still haven't gotten the correct information to make it work. The following is my code. stage.addEventListener(KeyboardEvent.KEY_DOWN, cNote); function cNote(event:KeyboardEvent):void { if (event.keyCode == Keyboard.SPACE) { keyCButton.gotoAndPlay(2) } } at frame 30 the code tells it to stop and then go back to frame 1 This works for the MouseEvent.CLICK but the KeyboardEvent does nothing.

  • QtWebkit and hasPendingEvents() always True

    - by Deorf
    Hello. I use project webkit2png (slightly appended) to take screenshots in Linux. On the server running the latest version QtWebkit and Python 2.6 On some sites (eg 118114.cn) problem and the application hangs forever. Debug shows that the problem in this code snippet: while self.__loading:    if timeout 0 and time.time() = cancelAt:       raise RuntimeError("Request timed out on %s" % url)    while QApplication.hasPendingEvents():       QCoreApplication.processEvents() Full version of the source code is available here (lines 270-275) Somehow Loading-event hangs and hasPendingEvents can not be False. Most of the screenshots are created normally, but sometimes due to some URL drops my app: ( Does anyone know how to solve this problem and why the event hangs?

  • Display constantly updating information in-place in command-line window using python?

    - by AndyL
    I am essentially building a timer. I have a python script that monitors for an event and then prints out the seconds that have elapsed since that event. Instead of an ugly stream of numbers printed to the command line, I would like to display only the current elapsed time "in-place"-- so that only one number is visible at any given time. Is there a simple way to do this? If possible I'd like to use built-in python modules. I'm on Windows, so simpler the better. (E.g. no X11).

  • Aren't passwords written in inputbox vulnerable through a stack trace ?

    - by loursonwinny
    Hello, I am not a guru of the stack tracing, at all. I even don't know how to get some. Anyway, I am wondering if entering a password entered in an inputbox is safe. Can't it be retrieved by getting a stack trace ? A password entered that way will be found in many places : Caption property of the TEdit Result of the function which creates the inputbox probably, a variable that stores the Result of the InputBox Command etc... If the answer is "yes, it is a vulnerability", then my world collapses :p. What can be done to avoid that vulnerability hole ? NOTE : The InputBox is an example but it can be with a "homebrewed" login prompt. InputBox is a Delphi command but I haven't tagged the question with the Delphi tag because I suppose that the question concerns any language. Thanks for reading

  • Is an object still connected to a list after FirstOrDefault?

    - by Cynthia
    Here's my code: Event thisEvent = (from i in list where (i.eventID == eventID) select i).FirstOrDefault(); if (thisEvent != null) { thisEvent.eventResolved = resolved; thisEvent.eventSequence.Add(item); } "list" is a collection of IEnumerable, i.e. IEnumerable<Event> list; What I'm wondering is: after creating thisEvent using FirstOrDefault, is thisEvent still connected to list? In other words, when I change the two properties, eventResolved and eventSequence, is "list" actually changed, or is thisEvent just some totally disconnected copy of an item in "list"?

  • Google Maps API - Marker not showing

    - by popnbrown
    I'm trying to add markers for every single row from a table, that sits on the page. The page is http://www.sravanks.com/first/2013ftcmap.php This is the JS code that's loading the markers: $(document).ready(function() { var mapOptions = { center: new google.maps.LatLng(39.740, -89.503), zoom: 7 }; var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions); var infowindow = new google.maps.InfoWindow(); /* City Markers */ var cityCircle = new Array(); var i = 0; $.each($('.events tr'), function(index, value) { var name = $(this).find('td:first()').html(); var address = $(this).find('.address').html(); var linkUrl = "http://www.sravanks.com/first/geocode.php?address=" + address; $.ajax({ url: linkUrl }).done(function(data){ var json = $.parseJSON(data.substring(0, data.length-1)); lat = json.results[0].geometry.location.lat; lng = json.results[0].geometry.location.lng; var latlng = new google.maps.LatLng(lat, lng); var marker = new google.maps.Marker({ position: latlng, map: map, icon: 'map-pointer-medium.gif' }); google.maps.event.addListener(marker, 'click', function() { infowindow.setContent(name); infowindow.open(map, marker); cityCircle[i] = new google.maps.Circle({strokeColor: '#00FF00', strokeOpacity: 0.8, strokeWeight: 2, fillColor: '#00FF00', fillOpacity: 0.35, map: map, center: latlng, radius: 144841}); i++; }); }); }); /*Team Markers*/ var markers = {}; var teamName, teamNumber, lat, lng, content; $.each($('.list tr'), function(index, value) { teamName = $(this).find('td.name').html(); teamNumber = $(this).find('td.number').html(); markers[teamNumber] = {}; lat = parseFloat($(this).find('td.lat').html()); lng = parseFloat($(this).find('td.lng').html()); content = "Name: " + teamName + "<br />Number: " + teamNumber; markers[teamNumber]['latlng'] = new google.maps.LatLng(lat, lng); markers[teamNumber]['marker'] = new google.maps.Marker({ position: markers[teamNumber]['latlng'], map: map }); google.maps.event.addListener(markers[teamNumber]['marker'], 'click', function() { infowindow.setContent(content); infowindow.open(map, markers[teamNumber]['marker']); }); }); google.maps.event.addListener(infowindow, 'closeclick', function() { for(var i=0;i<cityCircle.length;i++){ cityCircle[i].setMap(null); } }); }); I've got no errors, but the Team Markers do not show up. The strange thing is that the City Markers do show up. Some more info, the City Markers ajax call is just to a proxy that calls the google geocoding api. Again the link's at http://www.sravanks.com/first/2013ftcmap.php

  • Getting data into an input field from YUI Calendar with multi-select:true

    - by kylex
    <script type="text/javascript"> YAHOO.util.Event.onDOMReady(function(){ YAHOO.dateSelects.exc = new YAHOO.widget.Calendar("exc","excContainer", { title:"Choose a date:", close:true, multi_select:true }); YAHOO.dateSelects.exc.render(); YAHOO.util.Event.addListener( "excshowup", "click", YAHOO.dateSelects.exc.show, YAHOO.dateSelects.exc, true ); }); </script> <div class="calendarOuterContainer"> <div id="excContainer" class="calendarContainer"></div> </div> <a id="excshowup"><img src="/images/icons/calendar.png" /></a> The preceding code generates a YUI calendar with the ability to select multiple dates on one calendar. What I am having trouble figuring out is how to capture that data and place it inside a text input tag on the fly. So when a person clicks the close button, all the selected dates are populated inside the input tag. Suggestions?

  • Live() keyword not working on load with dynamic html images

    - by Sara Chipps
    I have images being dynamically added to a page, I don't seem to be able to get the 'load' event working dynamically with live(). This is the code I currently have: $('#largeImg' + nextUniqueItemID).hide(); $('#largeImg' + nextUniqueItemID).live('load' , function() { $('#loader' + nextUniqueItemID).hide(); $('#largeImg' + nextUniqueItemID).show(); }); with '#largeImg' + nextUniqueItemID being an image that was added to the page earlier in the function and '#largeImg' + nextUniqueItemID being a loading image. I feel as if I may be misusing "live" as it doesn't really need a listener but to trigger the event immediately.

  • Vertical Seek not progress value not showing on MainActivity textView

    - by Raju Gujarati
    I am try to display the progress value of the seekBar but when it comes to the execution, there is no update on the value being display on the TextView. I wonder what alternatives than putting two classes onto one big class in order to archive this aim ? The below is my code VerticalSeekBar.java package com.example.imagerotation; import android.content.Context; import android.graphics.Canvas; import android.util.AttributeSet; import android.view.MotionEvent; import android.widget.SeekBar; import android.widget.Toast; public class VerticalSeekBar extends SeekBar { public VerticalSeekBar(Context context) { super(context); } public VerticalSeekBar(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public VerticalSeekBar(Context context, AttributeSet attrs) { super(context, attrs); } protected void onSizeChanged(int w, int h, int oldw, int oldh) { super.onSizeChanged(h, w, oldh, oldw); } @Override protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(heightMeasureSpec, widthMeasureSpec); setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth()); } protected void onDraw(Canvas c) { c.rotate(-90); c.translate(-getHeight(), 0); super.onDraw(c); } @Override public boolean onTouchEvent(MotionEvent event) { if (!isEnabled()) { return false; } switch (event.getAction()) { case MotionEvent.ACTION_DOWN: case MotionEvent.ACTION_MOVE: case MotionEvent.ACTION_UP: int progress = getMax() - (int) (getMax() * event.getY() / getHeight()); setProgress(progress); onSizeChanged(getWidth(), getHeight(), 0, 0); //Toast.makeText(getContext(), String.valueOf(progress), Toast.LENGTH_SHORT).show(); break; case MotionEvent.ACTION_CANCEL: break; } return true; } } MainActvity.java package com.example.imagerotation; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.widget.TextView; public class MainActivity extends Activity { private VerticalSeekBar seek; private TextView by; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); seek = (VerticalSeekBar)findViewById(R.id.seekBar1); by = (TextView)findViewById(R.id.textView1); by.setText(String.valueOf(seek.getProgress())); } }

  • Safari on the iPhone & iPad gives colour feedback on touch, I want to stop this.

    - by Owen
    Clicking on an element which has a Javascript handler makes the element go have a 'grey overlay'. This is normally fine but I'm using event delegation to handle the touchdown events of many child elements. Because of the delegation the 'grey overlay' is appearing over the parent element and looks bad and confusing. I could attach event handlers to the individual elements to avoid the problem but this would be computationally very wasteful. I'd rather have some webkit css property that I can override to turn it off. I already have visual feedback in my app so the 'grey overlay' is not needed. Any ideas?

  • Database Error django

    - by Megan
    DatabaseError at /admin/delmarva/event/ no such column: delmarva_event.eventdate I created a class in my models.py file: from django.db import models from django.contrib.auth.models import User class Event(models.Model): eventname = models.CharField(max_length = 100) eventdate = models.DateField() eventtime = models.TimeField() address = models.CharField(max_length = 200) user = models.ForeignKey(User) def __unicode__(self): return self.eventname and now when i try to view my events in my admin or my main_page it gives me the error that there is no eventdate. I tried syncing the db again but nothing changed. Also, I hashtagged eventdate out to see if I get a different error and then it states that delmarva_event.eventtime does not exist as well. I It is weird because it does not have a problem with eventname. Any suggestions would be greatly appreciated!

  • Best practice for handling memory leaks in large Java projects?

    - by knorv
    In almost all larger Java projects I've been involved with I've noticed that the quality of service of the application degrades with the uptime of the container. This is most probably due to memory leaks in the code. The correct way to solve this problem is obviously to trace back to the root cause of the problem and fix the leaks in the code. The quick and dirty way of solving the problem is simply restarting Tomcat (or whichever servlet container you're using). These are my three questions: Assume that you choose to solve the problem by tracing the root cause of the problem (the memory leaks), how would you collect data to zoom in on the problem? Assume that you choose the quick and dirty way of speeding things up by simply restarting the container, how would you collect data to choose the optimal restart cycle? Have you been able to deploy and run projects over an extended period of time without ever restarting the servlet container to regain snappiness? Or is an occasional servlet restart something that one has to simply accept?

  • jquery - targetting a select using $this

    - by Maureen
    I am trying to get individual selects (which have the same class as other selects) to respond to a .change function, however it only works on one of the selects. If you test out this code it will make more sense. Try to add a few "ON/OFF events", and then select "Specified Time" in the various selects. You'll see only the first one responds. Any ideas? Thanks! Please see the following code: $(document).ready(function() { var neweventstring = '<div class="event">Turns <select name="ONOFF"><option value="On">ON</option><option value="Off">OFF</option></select> at: <select name="setto" class="setto"><option>Select Time</option><option value="Sunrise">Sunrise</option><option value="Sunset">Sunset</option><option value="specifiedtime">Specified Time</option></select></div>'; $('#addmondaysevent').click(function () { $('#monday .events').append(neweventstring); }); $('.setto').change(function() { alert('The function is called'); if($("option:selected", this).val() =="specifiedtime"){ alert('If returns true'); $(this).css("background-color", "#cc0000"); $(this).after('<div class="specifictime"><input type="text" value="00" style="width:30px"/> : <input type="text" value="00" style="width:30px"> <select name="ampm"><option value="AM" selected>AM</option><option value="PM">PM</option></select></div>') } }); }); And my HTML: <div id="monday"> <h2>Mondays</h2> <div class="events"> <div class="event"> Turn <select name="ONOFF"> <option value="On">ON</option> <option value="Off">OFF</option> </select> at: <select name="setto" class="setto"> <option>Select Time</option> <option value="Sunrise">Sunrise</option> <option value="Sunset">Sunset</option> <option value="specifiedtime">Specified Time</option> </select> </div> [<a id="addmondaysevent">Add an ON/OFF event</a>] </div> </div>

  • Can't read output of httpservice

    - by tag
    I have an HTTPservice that uses id="myhttp" url="site.com/script.php" method="POST" resultFormat="xml" script.php returns $output = '' . $worked . ''; echo $output; Problem is when I try to read worked, it tells me the variable worked is not there event.result.worked myhttp.lastResult.worked The only thing that works is using toString() myhttp.lastResult.toString() or event.result.toString() What am I doing wrong? I plan to add other variables to the output time, so need to access each time and worked separately. I may also need to return multiple responses each with their own worked and time values. How do I do that. I was thinking to not use XML. Is there a more lightweight option. Flex shows I have the following options: array e4x flashvars object text xml

  • Matlab - Propagate unit vectors on to the edge of shape boundaries

    - by Graham
    Hi I have a set of unit vectors which I want to propagate on to the edge of shape boundary defined by a binary image. The shape boundary is defined by a 1px wide white edge. I also have the coordinates of these points stored in a 2 row by n column matrix. The shape forms a concave boundary with no holes within itself made of around 2500 points. What would be the best method to do this? Are there some sort of ray tracing algorithms that could be used? Or would it be a case of taking the unit vector and multiplying it by a scalar and testing after multiplication if the end point of the vector is outside the shape boundary. When the end point of the unit vector is outside the shape, just find the point of intersection? Thank you very much in advance for any help!

  • Placeholder containing dynamic table is empty unless I create table twice

    - by Mike O.
    I am dynamically creating a table that contains a textbox in each cell. The table is put in a placeholder control. Everything displays perfectly. The problem is when I go to retrieve the values entered in the cells. I have the code to generate the table in a separate method called CreateTable(). In order for my program to find a table in the placeholder when I go to save, I have to run CreateTable() in a postback event AND in the PageLoad event. If I call CreateTable() in only one of those places and I try to save, it says the placeholder is empty and, therefore, I cannot save the textbox contents. I've tried calling CreateTable() from InitLoad but that doesn't work because it needs to reference values from three static controls: 1 dropdown, 1 listbox, and 1 calendar control, which I don't believe have had their viewstate rendered yet. Anyone have any ideas? It would sure be nice not to have to double the number of database calls just to make this work.

  • jQuery blockUI and AJAX POST

    - by oompahloompah
    I am using jQuery BlockUI in a project. For a particular user action, I want to block the UI, and then POST data to the server. When the timeout event occurs OR the server returns, I want to unblock the page. I can't seem to implement this behaviour. This is what I have so far (not working) $(document).ready(function(){ $('#test').click(function(event){ $.blockUI({ message: $('#syntax-chk') }); $.ajax({ type: 'POST', url: 'www.example.com', data: somedata, dataType: "json" }); setTimeout(function() { $.unblockUI({ onUnblock: function(){ alert('onUnblock'); } }); }, 2000); }); can anyone spot what I may be doing wrong?

Probably I should change the source code of TOLEContainer adding this event myself, but I don't know where is the best place for it. Can you advice some method?

  • UseConcMarkSweepGC verbose gc output shows memory drops

  • javascript window.close, once again

    - by John Kjøller
    Im sorry if I havent done my research properly, - but couldnt find the answer I needed, so here goes: From my main page I open a new window using mainPlayer = window.open(); This window stays open until user clicks on a mainPlayer.close(); event. (or simply x closes the window) However, the idea is to make it possible to let the player keep playing, while browsing around the rest of the pages. But as soon as the user leaves the page that opened the mainPlayer window, the reference to the mainPlayer window seem to be lost. How do I, from the site's other pages, check if the mainPlayer window is open and close it on a click event? Thx John

  • Forcing A Postback Asp.Net

    Please take a look at the following click event... Protected Sub btnDownloadEmpl_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDownloadEmpl.Click Dim emplTable As DataTable = SiteAccess.DownloadEmployee_H() Dim d As String = Format(Date.Now, "d") Dim ad() As String = d.Split("/") Dim fd As String = ad(0) & ad(1) Dim fn As String = "E_" & fd & ".csv" Response.ContentType = "text/csv" Response.AddHeader("Content-Disposition", "attachment; filename=" & fn) CreateCSVFile(emplTable, Response.Output) Response.Flush() Response.End() lblEmpl.Visible = True End Sub This code simply exports data from a datatable to a csv file. The problem here is lblEmpl.Visible=true never gets hit because this code doesnt cause a postback to the server. Even if I put the line of code lblEmpl.Visible=true at the top of the click event the line executes fine, but the page is never updated. How can I fix this?
