  • Issue in event.PreventDefault()

    - by Prathiba
    I'm using twitter bootstrap in my application. i gave e.preventDefault for link button in $(document).reday(), but it is not working. Here is my code: Master page: <a id="lnkLogout" href="javascript:void(0);" onclick="PageLogout();"><i class="icon-off"> </i>Logout</a> <script type="text/javascript" language="javascript"> $(document).ready(function () { $('#lnkLogout').click(function (e) { e.preventDefault(); }); }); function PageLogout() { //Code for logout from the application.... } </script> SampleDefaultPage.aspx : <div class="row-fluid"> <div class="form-horizontal"> <h4 class="header blue bolder smaller"> Contact</h4> <div class="control-group"> <label for="form-field-email" class="control-label"> Email</label> <div class="controls"> <input type="text" style="width:200px;" data-val="true" data-val-required="Mobile Number is required." id="txtEmail"> <div class="space-3"> </div> <span data-valmsg-replace="true" data-valmsg-for="txtEmail" class="field-validation-valid text-warning red"></span> </div> </div> <div class="control-group"> <label for="form-field-website" class="control-label"> Phone Number</label> <div class="controls"> <input type="text" style="width:200px;" id="txtPhno"> </div> </div> </div> I have given txtEmail as mandatory field. if i left that field blank and click on Logout button in Master page, it says txtEmail is required. i dint do any validation in Logout onclick event. I have given preventDefault for Logout link. But still facing an issue. I should be able to logout even though txtEmail is left blank. Thank you all in advance for your response.

  • Difficulty with jQuery and input keydown event

    - by Rosarch
    I am making a simple JavaScript enhanced list. I want it to be a list of inputs, each with an 'Add' and 'Remove' button. If the user clicks 'Add', a new li will be added. If the user clicks 'Remove', that li will be removed. It works fine, except for hitting "enter" in an <input>. Currently, it always causes the Remove.click event handler to fire, unless there's only one item in the list. I'm not sure why. How can I suppress this? Here is the complete jQuery. My attempt to fix the "enter" issue is commented out, and it doesn't work. I suspect that I could be designing this code better; if you see an improvement I'd love to hear it. function make_smart_list(list) { var ADD_CLASS = 'foo-widget-Add'; var REMOVE_CLASS = 'foo-widget-Remove'; var jq_list = $(list); jq_list.parents('form').submit(function() { return false; }); function refresh_handlers() { jq_list.find(sprintf('.%s, .%s', REMOVE_CLASS, ADD_CLASS)).unbind('click'); // jq_list.find('input').unbind('submit'); // // jq_list.find('input').submit(function() { // var jq_this = $(this); // var next_button = jq_this.nextAll('button'); // if (next_button.hasClass(ADD_CLASS)) { // next_button.nextAll('button').click(); // return; // } // // if (next_button.hasClass(REMOVE_CLASS)) { // return false; // } // // }); jq_list.find("." + REMOVE_CLASS).click(function() { var jq_this = $(this); jq_this.parent().remove(); refresh_handlers(); return false; }); jq_list.find("." + ADD_CLASS).click(function() { var jq_this = $(this); if (jq_this.prevAll('input').val() == '') { return; } jq_this.parent().clone().appendTo(jq_this.parent().parent()); jq_this.parent().next().find('input').val('').focus(); jq_this.removeClass(ADD_CLASS).addClass(REMOVE_CLASS); jq_this.text('Remove'); refresh_handlers(); return false; }); } refresh_handlers(); } (sprintf is another script I have.)

  • What is a “pretty and proper OO” way for handling sessions and authentication?

    - by asdfqwer
    Is coupling these two concepts a bad approach? As of right now I'm delegating all session handling and whether or not a user desires to logout in my config.inc file. As I was writing my Auth class I started wondering whether or not my Auth class should be taking care of most of the logic in my config.inc. Regardless, I'm sure there's a more elegant way of handling this... Here is what I have in my config.inc (also a large chunk of this code is based on a reply I found on SO except I can't find the source ._.): ini_set('session.name', 'SID'); # session management session_set_cookie_params(24*60*60); // set SID cookie lifetime session_start(); if(isset($_SESSION['LOGOUT']) { session_destroy(); // destroy session data $_SESSION = array(); // destroy session data sanity check setcookie('SID', '', time() - 24*60*60); // destroy session cookie data #header('Location: '.DOCROOT); } elseif(isset($_SESSION['SID_AUTH'])) { // verify user has authenticated if (!isset($_SESSION['SID_CREATED'])) { $_SESSION['SID_CREATED'] = time(); } elseif (time() - $_SESSION['SID_CREATED'] > 6*60*60) { // session started more than 6 hours ago session_regenerate_id(); // reset SID value $_SESSION['SID_CREATED'] = time(); // update creation time } if (isset($_SESSION['SID_MODIFIED']) && (time() - $_SESSION['SID_MODIFIED'] > 12*60*60)) { // last request was more than 12 hours ago session_destroy(); // destroy session data $_SESSION = array(); // destroy session data sanity check setcookie('SID', '', time() - 24*60*60); // destroy session cookie data } $_SESSION['SID_MODIFIED'] = time(); // update last activity time stamp }

  • Event Driven Communication in Game Engine - Yes or No?

    - by Bunkai.Satori
    As I am reading book Game Coding Complete (http://www.amazon.com/Game-Coding-Complete-Third-McShaffry/dp/1584506806/ref=sr_1_1?ie=UTF8&qid=1295978774&sr=8-1), the author recommend Event Driven communication among the all game objects and modules. Basicaly, all the living game actors and object should communicate with the key modules (Physics, AI, Game Logic, Game View, etc..) via internal event messaging system. This would mean designing efficient event manager as well. My question is, whether this is proven and recommended approach. If it is not properly designed, it might mean consuming a lot of CPU cycles, which can be used elsewhere. This is especially true, if the game is targetted for mobile platform. What is your opinion and recommendation, please?

  • Why do we need the "event" keyword while defining events ?

    - by Puneet Dudeja
    I don't understand why do we need the "event" keyword while defining events, when we can do the same thing without using "event" keyword, just by using the delegates. e.g. public delegate void CustomEventHandler(int a, string b); public event CustomEventHandler customEvent; customEvent += new CustomEventHandler(customEventHandler); customEvent(1,"a"); // Raising the event Here if I remove the "event" keyword from the second line, then also I can raise the event by invoking the delegate. Can anybody please tell me why is this event keyword needed ?

  • Event bubbling with img tags?

    - by Kenny Bones
    I did some googling and figured I'm probably experiencing so called "event bubbling" that I've never heard of but are not surprised by it's existance. I want it to fire only once and I'm wondering how to fix this. Basically, I have this small code snippet: $('.bggallery_images').click(function () { alert('test'); }); This is supposed to fire once from a php snippet that basically adds an image of each image from a specific folder. It then outputs an echo string where each image has the class of "bggallery_images". PHP snippet looks like this: <?php $dirname = "img"; $images = scandir($dirname); $ignore = Array(".", ".."); foreach($images as $file) { if(!in_array($file, $ignore)) { echo "<img class=\"bggallery_images\" src=\"$dirname/$file\" />"; }; } ?> This all generates the html markup that looks like this for each image: <img src="img/WhitePattern6.gif" class="bggallery_images"> What is happening here? Here's the rendered output from FireBug: <div id="gallery_lightbox" style="height: 215px; z-index: 4; display: block;"> <div id="close"></div> <h2><cufon class="cufon cufon-canvas" alt="Velg " style="width: 39px; height: 20px;"><canvas width="49" height="23" style="width: 49px; height: 23px; top: -4px; left: 0px;"></canvas><cufontext>Velg </cufontext></cufon><cufon class="cufon cufon-canvas" alt="bakgrunnsbilde" style="width: 123px; height: 20px;"><canvas width="129" height="23" style="width: 129px; height: 23px; top: -4px; left: 0px;"></canvas><cufontext>bakgrunnsbilde</cufontext></cufon></h2> <div class="bggallery_images">testererererer</div> <img src="img/Bakgrunner/4462-v4.jpg" class="bggallery_images"><img src="img/Bakgrunner/5922.gif" class="bggallery_images"><img src="img/Bakgrunner/BluePattern.gif" class="bggallery_images"><img src="img/Bakgrunner/Brown1.gif" class="bggallery_images"><img src="img/Bakgrunner/Brown2Pattern.jpg" class="bggallery_images"><img src="img/Bakgrunner/BrownPattern.jpg" class="bggallery_images"><img src="img/Bakgrunner/Brownn.gif" class="bggallery_images"><img src="img/Bakgrunner/GrayPattern.gif" class="bggallery_images"><img src="img/Bakgrunner/GreenPattern3.gif" class="bggallery_images"><img src="img/Bakgrunner/OrangePattern.gif" class="bggallery_images"><img src="img/Bakgrunner/PurplePattern.gif" class="bggallery_images"><img src="img/Bakgrunner/PurplePattern2.gif" class="bggallery_images"><img src="img/Bakgrunner/RedPattern3.gif" class="bggallery_images"><img src="img/Bakgrunner/RedPattern4.gif" class="bggallery_images"><img src="img/Bakgrunner/RedPattern5.gif" class="bggallery_images"><img src="img/Bakgrunner/Tiled_Wallpaper__Green_Texture_by_knitetgantt.png" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern4.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern5.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern6.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern7.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePurple.jpg" class="bggallery_images"><img src="img/Bakgrunner/YellowPattern.gif" class="bggallery_images"><img src="img/Bakgrunner/vintage-wallpaper.jpg" class="bggallery_images"> </div>

  • Javascript tabs: call event onclick

    - by Joris
    I got some code I need to change. it is build by others, and not very neat... There is a javascript tabcontrol, containing 4 tabs, which contains gridviews. All the 4 gridviews are build during the load of the page, but I want them to load, when you activate the tabs (as it is possible to watch the side, while you don't need the specific gridviews to see) So, my question is: how to call an event (that loads the gridview) from an javascript tab? how the tabs are generated: (generated code, I know, horrible) var obj = 0; var oid = 0; var otb = 0; var myTabs = new Array(); var myTabitems = new Array(); var myTabitem = new Array(); var myTabContent = new Array(); var myLists = new Array(); function showTabContent(tab) { tb = tab.obj; id = tab.nr; if (myTabs[tb].oid != -1) { myTabs[tb].myTabContent[myTabs[tb].oid].style.display = 'none'; myTabs[tb].myTabitem[myTabs[tb].oid].className -= " active"; } myTabs[tb].myTabContent[id].style.display = 'block'; myTabs[tb].myTabitem[id].className += " active"; myTabs[tb].oid = id; } function boTabs() { var myBlocks = new Array(); myBlocks = document.getElementsByTagName("div"); var stopit = myBlocks.length; for (var g = 0; g < stopit; g++) { if (myBlocks[g].className == "tabs") { myTabs.push(myBlocks[g]); } } var stopit2 = myTabs.length; for (var i = 0; i < stopit2; i++) { myTabs[i].myLists = myTabs[i].getElementsByTagName("ul"); if (myTabs[i].myLists[0].className == "tabs") { myTabs[i].myTabitems = myTabs[i].myLists[0].getElementsByTagName("li"); } var stopit3 = myTabs[i].myTabitems.length; myTabs[i].obj = i; myTabs[i].myTabitem = new Array(); myTabs[i].myTabContent = new Array(); for (var j = 0; j < stopit3; j++) { myTabs[i].myTabitem.push(myTabs[i].myTabitems[j]); myTabs[i].myTabitem[j].nr = j; myTabs[i].myTabitem[j].obj = i; myTabs[i].myTabitem[j].onclick = function() { showTabContent(this); }; } var myTabDivs = myTabs[i].getElementsByTagName("div"); for (var j = 0; j < myTabDivs.length; j++) { if (myTabDivs[j].className == "tabcontent") { myTabs[i].myTabContent.push(myTabDivs[j]); } } myTabs[i].myTabitem[0].className += " active"; myTabs[i].myTabContent[0].style.display = 'block'; myTabs[i].oid = 0; myTabDivs = null; } myBlocks = null; } onload = boTabs;

  • jQuery , Trigger change event on newly created elements

    - by kwhohasamullet
    Hi Guys, I have a button in a form that when clicked adds another set of form fields, In these form fields there are 2 drop downs where the contents of the 2nd dropdown rely on what is selected in the first dropdown... What i want to do is when the new form field button is clicked for the new items to be added and then the change event to be triggered on the drop down that was created so what only that drop down changes and not all the drop downs with the same name currently in that form. THe first drop down is called product Category The code for the addFormField function is: function addFormField() { var id = document.getElementById("field_id").value; $("#products").append("<table width='600' cellpadding='5' cellspacing='0' class='Add_Products' id='row" + id + "'><td width='250' class='left'><label>Select Product Category</label></td><td class='right' ><label><select name='" + id + "' id='ProductCategory'><?php foreach($categories as $key=>$category){ echo "<option value=".$key.">".$category."</option>"; } ?></select></label></td></tr><tr><td width='250' class='left'><label>Select Product Template</label></td><td class='right' ><label><select name='data[QuoteItem][" + id + "][product_id]' id='QuoteItem" + id + "product_id' class='Product' title='" + id + "'></select></label></td></tr><tr ><td class='left'>Name</td><td class='right'><label><input name='data[QuoteItem][" + id + "][name]' type='text' id='QuoteItem" + id + "name' size='50' /></label></td></tr><tr ><td class='left'>Price (ex GST)</td><td class='right'><input type='text' name='data[QuoteItem][" + id + "][price]' id='QuoteItem" + id + "price' onchange='totalProductPrice();' class='quote-item-price' value='0' /></td></tr><tr><td class='left'>Description</td><td class='right'><label><textarea name='data[QuoteItem][" + id + "][description]' cols='38' rows='5' id='QuoteItem" + id + "description'></textarea></label></td></tr><tr><td><a href='#' onClick='removeFormField(\"#row" + id + "\"); return false;'>Remove</a></td></tr></table>"); $('#row' + id).highlightFade({ speed:1000 }); id = (id - 1) + 2; document.getElementById("field_id").value = id; } The code that detects change in ProductCategory dropdown and triggers the AJAX is below: $("select#ProductCategory").live('change', function(){ var url = base + "/quotes/productList/" + $(this).val() + ""; var id = $(this).attr('name'); $.getJSON(url,{id: $(this).val(), ajax: 'true'}, function(j){ var options = ''; options += '<option value="0">None</option>'; $.each(j, function(key, value){ options += '<option value="' + key + '">' + value + '</option>'; }) $("select#QuoteItem" + id + "product_id").html(options); }) }).trigger('change'); I have been trying all afternoon to work this out and the closest one i got to work applied the returned ajax values to all items. Currently using the live function people can add new fields and are able to use the drops down independant of each other dropdown but its only when the field is first added that i have trouble getting is populated Thanks in advance for any help

  • Event handle in drop-down menu.

    - by QLiu
    Hello fellows, I am trying to develop a dynamic drop down menu by a customized widget style The custom widget has two main features: Read user's location cookies variable to set the proper contact phone number in the CP pages When users select on the drop down menu, it triggers onChange event, it re-select the contact phone number based on users' selections, but it won't reset the location cookies. My widgets conatins two files: Controller.php: Simply one, it uses to handle get cookies variables class serial extends Widget { function __construct() { parent::__construct(); } function generateWidgetInformation() { $this->info['notes'] = "Serial Number search Box"; } function getData() { //Get cookies code will go here, and pass to view.php $this->data['locale'] = 'gb';// for test purpose now } } view.php is about Presentation layer contains HTML, which get the data from my controller <div style="border: 1px solid black; display: block;" id="<?=$this->instanceID;?>"></div> <script>locale2contact('<?=$this->data['locale']?>', '<?=$this->instanceID;?>');</script> And then the Javascript function, call locale2contact var element_id =''; //Define Global Variables, //Receive the cookies locale, and instance id from view.php function locale2contact(locale, instance_id) { var details = ''; this.element_id=instance_id; //assing the instance id into global variable // alert(instance_id); //Check whether we got the instance id from view files if (locale == 'gb') details = 'UK Contact Details<br>' + build_dropdown(locale); else if (locale == 'fr') details = 'French Contact Details<br>'+build_dropdown(locale); else if (locale == 'be') details = 'Belgian Contact Details<br>'+ build_dropdown(locale); else details = 'Unknown Contact Detail'; writeContactInfo(details); } //Build the drop down menu with pre-selected option by using cookies. function build_dropdown(locale) { var dropdown = '<select onChange=changeContactInfo(this.options[selectedIndex].text)>'; dropdown += '<option' + (locale == 'gb' ? ' selected' : '') + '>UK</option>'; dropdown += '<option' + (locale == 'be' ? ' selected' : '') + '>Belgium</option>'; dropdown += '</select>'; return dropdown; } // Not smart way in here, once the people select the drop down box, it reselect the drop down menu and reset the contact info function changeContactInfo(selected) { var details =''; //alert(this.element_id); //alert(locale); if (selected == 'UK') details = 'UK Contact Details<br>' + build_dropdown2(selected); else if (selected == 'fr') details = 'French Contact Details<br>'+ build_dropdown2(selected); else if (selected == 'Belgium') details = 'Belgian Contact Details<br>'+ build_dropdown2(selected); else details = 'Unknown Contact Detail'; writeContactInfo(details); } //Build the drop down menu function build_dropdown2(selected) { var dropdown = '<select onChange=changeContactInfo(this.options[selectedIndex].text)>'; dropdown += '<option' + (selected == 'UK' ? ' selected' : '') + '>UK</option>'; dropdown += '<option' + (selected == 'Belgium' ? ' selected' : '') + '>Belgium</option>'; dropdown += '</select>'; return dropdown; } //Back to view function writeContactInfo(details) { document.getElementById(this.element_id).innerHTML = details; //update the instance field in view } Javascript function is not efficient. As you see, I got two similar duplicate functions to handle events. Users go to the page, the widget read the cookies variable to display contact info (locale2contact)and preselect the drop-down menu (function build_dropdown) If users select the drop down menu, the displya contact info change (function changeContactInfo), and then I need to rebuild the drop down menu with user previously selection (function build_dropdown2). I am looking for best practices for adding this functionality to RightNow widget. Thank you. I really do not like the way i am doing now. It works; but the code looks bad.

  • Failed to load viewstate

    - by Jen
    OK have just started getting this error and I'm not sure why. I have a hosting page which has listview and a panel with a usercontrol. The listview loads up records with a linkbutton. You click the link button to edit that particular record - which gets loaded up in the formview (within the usercontrol) which goes to edit mode. After an update occurs in the formview I'm triggering an event which my hosting page is listening for. The hosting page then rebinds the listview to show the updated data. So this all works - but when I then go to click on a different linkbutton I get the below error: Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.3) Timestamp: Fri, 18 Jun 2010 03:15:54 UTC Message: Sys.WebForms.PageRequestManagerServerErrorException: Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.

My event listener does this: protected void RatesEditDate1_EditDateRateUpdated() { if (IsDateRangeValid(txtDisplayFrom, txtDisplayTo)) { PropertyAccommodationRates1.DataBind(); } else { pnlViewAccommodationRates.Visible = false; } divEditRate.Visible = false; } When I click my link button - it should be hitting this but the second time round it errors before hitting the breakpoint: protected void RatesEditDate1_EditDateRateSelected(DateTime theDateTime) { // make sure everything else is invisible pnlAddAccommodation.Visible = false; pnlViewEditAccommodations.Visible = false; RatesEditDate1.TheDateTime = theDateTime; RatesEditDate1.PropertyID = (int)Master.PropertyId; if (!String.IsNullOrEmpty(Accommodations1.SelectedValue)) { RatesEditDate1.AccommodationTypeID = Convert.ToInt32(Accommodations1.SelectedValue); } else { RatesEditDate1.AccommodationTypeID = 0; } divEditRate.Visible = true; } So my listview appears to be being rebound successfully - I can see my changed data.. I just don't know why its complaining about viewstate when I click on the linkbutton. Or is there a better way to update the data in my listview? My listview and formview are bound to objectdata sources (in case that matters) Thanks for the help!

    I have a UIView that contains a UIScrollView and I want to be able to capture the "Touch Down" event in the UIView any time the user taps on the UIScrollView. I've tried including all the touchesBegan/Ended/Cancelled handlers in my UIViewController but none of them get fired when tapping inside the UIScrollView contained in the main UIView. What is the best way to accomplish this?

    In Windows Server 2008 and Windows 7 there are new Events categorized under "Applications and Services Logs". There is also a subfolder called Microsoft which has tons of subfolders as well. Is there any way to collect these events through WMI? For the regular "Windows Logs" such as Application and Security, it is possible to use the Win32_NTLogEvent WMI class in the cimv2 namespace. However, this class does not provide access to the new Microsoft event logs. Any ideas?

  • accepting click events in RelativeLayout

    - by skooter
    Ok, I have a RelativeLayout with a few TextViews as children <RelativeLayout android:id="@+id/shift_parent_name" android:layout_width="fill_parent" android:layout_weight="0.25" > <TextView android:id="@+id/shift_parent_nametitle" android:text="@string/shift_parent_nametitle" style="@style/header_text" /> <TextView android:id="@+id/shift_parent_namefield" android:layout_alignParentRight="true" android:layout_below="@id/shift_parent_nametitle" style="@style/wrap" /> How do I go about using the RelativeLayout as the button to react to a click event if any part of the area is pressed?

  • Mootools 1.2.4 delegation not working in IE8...?

    - by michael
    Hey there everybody-- So I have a listbox next to a form. When the user clicks an option in the select box, I make a request for the related data, returned in a JSON object, which gets put into the form elements. When the form is saved, the request goes thru and the listbox is rebuilt with the updated data. Since it's being rebuilt I'm trying to use delegation on the listbox's parent div for the onchange code. The trouble I'm having is with IE8 (big shock) not firing the delegated event. I have the following HTML: <div id="listwrapper" class="span-10 append-1 last"> <select id="list" name="list" size="20"> <option value="86">Adrian Franklin</option> <option value="16">Adrian McCorvey</option> <option value="196">Virginia Thomas</option> </select> </div> and the following script to go with it: window.addEvent('domready', function() { var jsonreq = new Request.JSON(); $('listwrapper').addEvent('change:relay(select)', function(e) { alert('this doesn't fire in IE8'); e.stop(); var status= $('statuswrapper').empty().addClass('ajax-loading'); jsonreq.options.url = 'de_getformdata.php'; jsonreq.options.method = 'post'; jsonreq.options.data = {'getlist':'<?php echo $getlist ?>','pkey':$('list').value}; jsonreq.onSuccess = function(rObj, rTxt) { status.removeClass('ajax-loading'); for (key in rObj) { status.set('html','You are currently editing '+rObj['cname']); if ($chk($(key))) $(key).value = rObj[key]; } $('lalsoaccomp-yes').set('checked',(($('naccompkey').value > 0)?'true':'false')); $('lalsoaccomp-no').set('checked',(($('naccompkey').value > 0)?'false':'true')); } jsonreq.send(); }); }); (I took out a bit of unrelated stuff). So this all works as expected in firefox, but IE8 refuses to fire the delegated change event on the select element. If I attach the change function directly to the select, then it works just fine. Am I missing something? Does IE8 just not like the :relay? Sidenote: I'm very new to mootools and javascripting, etc, so if there's something that can be improved code-wise, please let me know too.. Thanks!

  • Is there a way to detect when a WSS default.aspx page is updated?

    - by Alan
    That is detect when the user makes web part changes and selects to exit editing the page. I want to be able to capture a page event, then create a SharePoint task to instruct a user to translate that page to another language (note that MOSS and variations is not an option because the client wants to use the free version of SharePoint). So the customer wants essentially the same WSS site in multiple languages.

  • C program using inotify to monitor multiple directories along with sub-directories?

    - by lakshmipathi
    I have program which monitors a directory (/test) and notify me. I want to improve this to monitor another directory (say /opt). And also how to monitor it's subdirectories , current i'll get notified if any changes made to files under /test . but i'm not getting any inotifcation if changes made sub-directory of /test, that is touch /test/sub-dir/files.txt .. Here my current code - hope this will help /* Simple example for inotify in Linux. inotify has 3 main functions. inotify_init1 to initialize inotify_add_watch to add monitor then inotify_??_watch to rm monitor.you the what to replace with ??. yes third one is inotify_rm_watch() */ #include <sys/inotify.h> int main(){ int fd,wd,wd1,i=0,len=0; char pathname[100],buf[1024]; struct inotify_event *event; fd=inotify_init1(IN_NONBLOCK); /* watch /test directory for any activity and report it back to me */ wd=inotify_add_watch(fd,"/test",IN_ALL_EVENTS); while(1){ //read 1024 bytes of events from fd into buf i=0; len=read(fd,buf,1024); while(i<len){ event=(struct inotify_event *) &buf[i]; /* check for changes */ if(event->mask & IN_OPEN) printf("%s :was opened\n",event->name); if(event->mask & IN_MODIFY) printf("%s : modified\n",event->name); if(event->mask & IN_ATTRIB) printf("%s :meta data changed\n",event->name); if(event->mask & IN_ACCESS) printf("%s :was read\n",event->name); if(event->mask & IN_CLOSE_WRITE) printf("%s :file opened for writing was closed\n",event->name); if(event->mask & IN_CLOSE_NOWRITE) printf("%s :file opened not for writing was closed\n",event->name); if(event->mask & IN_DELETE_SELF) printf("%s :deleted\n",event->name); if(event->mask & IN_DELETE) printf("%s :deleted\n",event->name); /* update index to start of next event */ i+=sizeof(struct inotify_event)+event->len; } } }

  • Flash AS3 Mysterious Blinking MovieClip

    - by Ben
    This is the strangest problem I've faced in flash so far. I have no idea what's causing it. I can provide a .swf if someone wants to actually see it, but I'll describe it as best I can. I'm creating bullets for a tank object to shoot. The tank is a child of the document class. The way I am creating the bullet is: var bullet:Bullet = new Bullet(); (parent as MovieClip).addChild(bullet); The bullet itself simply moves itself in a direction using code like this.x += 5; The problem is the bullets will trace for their creation and destruction at the correct times, however the bullet is sometimes not visible until half way across the screen, sometimes not at all, and sometimes for the whole traversal. Oddly removing the timer I have on bullet creation seems to solve this. The timer is implemented as such: if(shot_timer == 0) { shoot(); // This contains the aforementioned bullet creation method shot_timer = 10; My enter frame handler for the tank object controls the timer and decrements it every frame if it is greater than zero. Can anyone suggest why this could be happening? EDIT: As requested, full code: Bullet.as package { import flash.display.MovieClip; import flash.events.Event; public class Bullet extends MovieClip { public var facing:int; private var speed:int; public function Bullet():void { trace("created"); speed = 10; addEventListener(Event.ADDED_TO_STAGE,addedHandler); } private function addedHandler(e:Event):void { addEventListener(Event.ENTER_FRAME,enterFrameHandler); removeEventListener(Event.ADDED_TO_STAGE,addedHandler); } private function enterFrameHandler(e:Event):void { //0 - up, 1 - left, 2 - down, 3 - right if(this.x > 720 || this.x < 0 || this.y < 0 || this.y > 480) { removeEventListener(Event.ENTER_FRAME,enterFrameHandler); trace("destroyed"); (parent as MovieClip).removeChild(this); return; } switch(facing) { case 0: this.y -= speed; break; case 1: this.x -= speed; break; case 2: this.y += speed; break; case 3: this.x += speed; break; } } } } Tank.as: package { import flash.display.MovieClip; import flash.events.KeyboardEvent; import flash.events.Event; import flash.ui.Keyboard; public class Tank extends MovieClip { private var right:Boolean = false; private var left:Boolean = false; private var up:Boolean = false; private var down:Boolean = false; private var facing:int = 0; //0 - up, 1 - left, 2 - down, 3 - right private var horAllowed:Boolean = true; private var vertAllowed:Boolean = true; private const GRID_SIZE:int = 100; private var shooting:Boolean = false; private var shot_timer:int = 0; private var speed:int = 2; public function Tank():void { addEventListener(Event.ADDED_TO_STAGE,stageAddHandler); addEventListener(Event.ENTER_FRAME, enterFrameHandler); } private function stageAddHandler(e:Event):void { stage.addEventListener(KeyboardEvent.KEY_DOWN,checkKeys); stage.addEventListener(KeyboardEvent.KEY_UP,keyUps); removeEventListener(Event.ADDED_TO_STAGE,stageAddHandler); } public function checkKeys(event:KeyboardEvent):void { if(event.keyCode == 32) { //trace("Spacebar is down"); shooting = true; } if(event.keyCode == 39) { //trace("Right key is down"); right = true; } if(event.keyCode == 38) { //trace("Up key is down"); // lol up = true; } if(event.keyCode == 37) { //trace("Left key is down"); left = true; } if(event.keyCode == 40) { //trace("Down key is down"); down = true; } } public function keyUps(event:KeyboardEvent):void { if(event.keyCode == 32) { event.keyCode = 0; shooting = false; //trace("Spacebar is not down"); } if(event.keyCode == 39) { event.keyCode = 0; right = false; //trace("Right key is not down"); } if(event.keyCode == 38) { event.keyCode = 0; up = false; //trace("Up key is not down"); } if(event.keyCode == 37) { event.keyCode = 0; left = false; //trace("Left key is not down"); } if(event.keyCode == 40) { event.keyCode = 0; down = false; //trace("Down key is not down") // O.o } } public function checkDirectionPermissions(): void { if(this.y % GRID_SIZE < 5 || GRID_SIZE - this.y % GRID_SIZE < 5) { horAllowed = true; } else { horAllowed = false; } if(this.x % GRID_SIZE < 5 || GRID_SIZE - this.x % GRID_SIZE < 5) { vertAllowed = true; } else { vertAllowed = false; } if(!horAllowed && !vertAllowed) { realign(); } } public function realign():void { if(!horAllowed) { if(this.x % GRID_SIZE < GRID_SIZE / 2) { this.x -= this.x % GRID_SIZE; } else { this.x += (GRID_SIZE - this.x % GRID_SIZE); } } if(!vertAllowed) { if(this.y % GRID_SIZE < GRID_SIZE / 2) { this.y -= this.y % GRID_SIZE; } else { this.y += (GRID_SIZE - this.y % GRID_SIZE); } } } public function enterFrameHandler(Event):void { //trace(shot_timer); if(shot_timer > 0) { shot_timer--; } movement(); firing(); } public function firing():void { if(shooting) { if(shot_timer == 0) { shoot(); shot_timer = 10; } } } public function shoot():void { var bullet = new Bullet(); bullet.facing = facing; //0 - up, 1 - left, 2 - down, 3 - right switch(facing) { case 0: bullet.x = this.x; bullet.y = this.y - this.height / 2; break; case 1: bullet.x = this.x - this.width / 2; bullet.y = this.y; break; case 2: bullet.x = this.x; bullet.y = this.y + this.height / 2; break; case 3: bullet.x = this.x + this.width / 2; bullet.y = this.y; break; } (parent as MovieClip).addChild(bullet); } public function movement():void { //0 - up, 1 - left, 2 - down, 3 - right checkDirectionPermissions(); if(horAllowed) { if(right) { orient(3); realign(); this.x += speed; } if(left) { orient(1); realign(); this.x -= speed; } } if(vertAllowed) { if(up) { orient(0); realign(); this.y -= speed; } if(down) { orient(2); realign(); this.y += speed; } } } public function orient(dest:int):void { //trace("facing: " + facing); //trace("dest: " + dest); var angle = facing - dest; this.rotation += (90 * angle); facing = dest; } } }
