• Is there anything on a local network or desktop environment that could effect JScript execution?

  - by uku

  I know this sounds odd. The JS on my project functions perfectly, except when the web site is accessed using computers at one specific company. To make things even more difficult, the JS fails only about 50% of the time when run from that company. The JS failure occurs with FireFox, Chrome, and IE. I have tested this myself using FF and Chrome on a thumb drive. The browsers on my thumb always display my project site perfectly, except when run from a computer on said company's network where they fail at the same rate as the installed browsers. My JS is using jQuery and making some Ajax calls. The Ajax calls are where the failure is occurring. To diagnose the problem I created a logging function for my Ajax calls and recorded success and failure. Over a one month period, there were only a handful of failures (about 1%) from all access points other than this company. Oddly enough, the Ajax calls in the logging function are not failing. There is nothing exotic there - Just Win XP SP3. I have never noticed any other unusual behavior from their network. The company is a division of a mega ISP and is on their corporate network. Any other suggestions for troubleshooting would be welcome.

• HTML5 Video Element on iPad doesn't fire onclick?

  - by bhups

  I am using the video element in my HTML as following:<div id="container" style="background:black; overflow:hidden;width:320px;height:240px" <video style="background:black;display:block" id="vdo" height="240px" width="320px" src="http://mydomain/vid.mp4"</video</div And in javascript I am doing this:var video=document.getElementById('vdo'); var container=document.getElementById('container'); video.addEventListener('click', function(e) { e.preventDefault(); console.log("clicked"); }, false); container.addEventListener('click', function(e) { e.preventDefault(); console.log("clicked"); }, false); On desktop safari/chrome everything is working fine. I can see two "clicked" in the console. But on ipad there is nothing. First I tried with iOS versin 3.2, then I updated it to the latest one 4.2.1 without any success.I found a similar question HTML5 Video Element on iPad doesn't fire onclick or touchstart events? where it suggests not to use controls in video tag and I am not using it.

• Handling Complex Rules in in GUI applciations (C++ or C#)

  - by Canacourse

  Im working on a dialog box in which several rules must be satisfied before the OK button is enabled. Currently any action on the page such as entering data or selecting an item from a drop down list (amongst other things) calls a single function called ProcessEvent() - this function handles all logic and either enables or disables the OK button. My problem is I finding it difficult making the rules concise and understandable. Some of the rules can be negated by another action on the dialog and I have now ended up with if else statements all over the place or which are difficult to read and follow & extend. The code below is a simplification of the problem but demonstrates it well. How do I handle this problem better (If its Possible) bool CWorkstation::ProcessEvent(void) { UpdateData(); CharCount = GetDlgItemInt(IDC_CharCount, NULL, FALSE); //get latest if ( IsDlgButtonChecked(IDC_USEDBNAME)) { if (!IsDlgButtonChecked(IDC_MAXDBNAME)) { EnableNext(TRUE); } } if (IsDlgButtonChecked(IDC_MAXDBNAME) && CharCount) { if (IsDlgButtonChecked(IDC_USEXMLNAME)) { if ( PrefixName.IsEmpty() ) { EnableNext(FALSE); } else { EnableNext(TRUE); } } } if (IsDlgButtonChecked(IDC_USEXMLNAME) && PrefixName.GetLength() > 1) { EnableNext(TRUE); } if ( IsDlgButtonChecked(IDC_WSAUTONAME) || IsDlgButtonChecked(IDC_RENAMEIFDUP)) { // TRACE("IDC_WSAUTONAME is Checked\n"); if ( IsDlgButtonChecked(IDC_USEXMLNAME) && PrefixName.GetLength() > 1 ) { if ( IsDlgButtonChecked(IDC_IDC_USESHORTNAME) ) { EnableNext(TRUE); } else if ( IsDlgButtonChecked(IDC_USELONGNAME) ) { EnableNext(TRUE); } else { EnableNext(FALSE); } } if ( !IsDlgButtonChecked(IDC_USEPREFIX) ) { if ( IsDlgButtonChecked(IDC_IDC_USESHORTNAME) || IsDlgButtonChecked(IDC_USELONGNAME) ) { EnableNext(TRUE); } } return false; } }

• Questions regarding detouring by modifying the virtual table

  - by Elliott Darfink

  I've been practicing detours using the same approach as Microsoft Detours (replace the first five bytes with a jmp and an address). More recently I've been reading about detouring by modifying the virtual table. I would appreciate if someone could shed some light on the subject by mentioning a few pros and cons with this method compared to the one previously mentioned! I'd also like to ask about patched vtables and objects on the stack. Consider the following situation: // Class definition struct Foo { virtual void Call(void) { std::cout << "FooCall\n"; } }; // If it's GCC, 'this' is passed as the first parameter void MyCall(Foo * object) { std::cout << "MyCall\n"; } // In some function Foo * foo = new Foo; // Allocated on the heap Foo foo2; // Created on the stack // Arguments: void ** vtable, uint offset, void * replacement PatchVTable(*reinterpret_cast<void***>(foo), 0, MyCall); // Call the methods foo->Call(); // Outputs: 'MyCall' foo2.Call(); // Outputs: 'FooCall' In this case foo->Call() would end up calling MyCall(Foo * object) whilst foo2.Call() call the original function (i.e Foo::Call(void) method). This is because the compiler will try to decide any virtual calls during compile time if possible (correct me if I'm wrong). Does that mean it does not matter if you patch the virtual table or not, as long as you use objects on the stack (not heap allocated)?

  I have this script that would let the user input a text and it would get translated into something else. It works only when the word has only 1 letter.

• sendto is returning ENOBUF

  - by user338159

  Hi, I am currently running an old system on Tru64 which involves lots of UDP sockets using the sendto() function. The sockets are used in our code to send messages to/from various processes and then eventually on to a thick client app that is connected remotely. Occasionally the socket to the thick client gets stuck, this can cause some of these messages to get built up. My question is how can I determine the current buffer size, and how do I determine the maximum message buffer. The code below gives a snippet of how I set up the port and use the sendto function. /* need to adjust the maximum size we can send on this / / as it needs to be able to cope with the biggest / / messages we send / lenlen = sizeof(len) ; / allow double for when the system is under load */ len = 2 * C_MAX_MESSAGE_DATA_SIZE ; lpos_setsockopt(FATAL, msg_socket,SOL_SOCKET, SO_SNDBUF, &len, lenlen, &error_no) ; result = sendto( msg_socket, (char *)message, (int)message_len, flags, dest_addr, addrlen); Note. We have ported this application to Linux and the problem does not seem to appear there. Any help would be greatly appreciated. Regards

• Why do you need "extern C" for in C++ callbacks to C functions?

  - by Artyom

  Hello, I find such examples in Boost code. namespace boost { namespace { extern "C" void *thread_proxy(void *f) { .... } } // anonymous void thread::thread_start(...) { ... pthread_create(something,0,&thread_proxy,something_else); ... } } // boost Why do you actually need this extern "C"? It is clear that thread_proxy function is private internal and I do not expect that it would be mangled as "thread_proxy" because I actually do not need it mangled at all. In fact in all my code that I had written and that runs on may platforms I never used extern "C" and this had worked as-as with normal functions. Why extern "C" is added? My problem is that extern "C" function pollute global name-space and they do not actually hidden as author expects. This is not duplicate! I'm not talking about mangling and external linkage. It is obvious in this code that external linkage is unwanted!

• Returning a reference from a Class member?

  - by nebukadnezzar

  Hi, I've a class that basically looks like this: class App { public function newTemplate($filename, $vars=array()) { $smarty = new Smarty; $smarty->compile_dir = $this->template_compile_path; if(count($vars) > 0) { foreach($vars as $v_key => $v_name) { $smarty->assign($v_key, $v_name); } } return $smarty; } } However, when I create a Instance of 'App', the reference to $smarty seems broken, as every call to the membermethods don't seem to do anything: $app = new App; $tpl = $app->newTemplate("index.tmpl"); $tpl->assign("foo", "bar"); // {$foo} does not appear with "bar" in the template Now I wonder why? Of course I tried to use references: ... public function &newTemplate() ... ... But that doesn't work. Variable references don't seem to work either: ... $tpl = &$app->newTemplate("index.tmpl"); ... What is causing PHP here not to return a proper reference? Help is very appreciated!

• JSP getParameter problem

  - by user236501

  I have a form, if the timer reach the form will auto redirect to the Servlet to update database. My problem now is if javascript redirect the window to servlet my request.getParameter is null. function verify(f,whichCase){ if(whichCase == "Submit"){ msg = "Are you sure that you want to submit this test?"; var i = confirm(msg) if(i){ parent.window.location = "sindex.jsp" } return i; } } I doing this because i got a iframe in my jsp. Timer update problem have to use iframe. So, when time up or user click submit parent.window.location can let me refresh parent window <form method="POST" action="${pageContext.request.contextPath}/TestServlet" onSubmit="return verify(this,whichPressed)"> My form when user click submit button within the timing, it will trigger the verify function to let user confirm submit. So inside my TestServlet i got this, because using javascript redirect request.getParameter("answer") this keep return me null. protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { if (request.getParameter("Submit") != null) { String ans = request.getParameter("answer"); Answer a = new Answer(ans, no); aa.CreateAnswer(an,t.getTestCode(),username); RequestDispatcher rd = request.getRequestDispatcher("/sindex.jsp"); rd.forward(request, response); } } Below are my timer when time up redirect to TestServlet trigger the doGet method if((mins == 0) && (secs == 0)) { window.alert("Time is up. Press OK to submit the test."); // change timeout message as required var sUrl = "TestServlet"; parent.window.location = sUrl // redirects to specified page once timer ends and ok button is pressed } else { cd = setTimeout("redo()",1000); }

• Avoiding duplication in setting properties on the task in Rake tasks

  - by Stray

  I have a bunch of rake building tasks. They each have unique input / output properties, but the majority of the properties I set on the tasks are the same each time. Currently I'm doing that via simple repetition like this: task :buildThisModule => "bin/modules/thisModule.swf" mxmlc "bin/modules/thisModule.swf" do |t| t.input = "src/project/modules/ThisModule.as" t.prop1 = value1 t.prop2 = value2 ... (And many more property=value sets that are the same in each task) end task :buildThatModule => "bin/modules/thatModule.swf" mxmlc "bin/modules/thatModule.swf" do |t| t.input = "src/project/modules/ThatModule.as" t.prop1 = value1 t.prop2 = value2 ... (And many more property=value sets that are the same in each task) end In my usual programming headspace I'd expect to be able to break out the population of the recurring task properties to a re-usable function. Is there a rake analogy for this? Some way I can have a single function where the shared properties are set on any task? Something equivalent to: task :buildThisModule => "bin/modules/thisModule.swf" mxmlc "bin/modules/thisModule.swf" do |t| addCommonTaskParameters(t) t.input = "src/project/modules/ThisModule.as" end task :buildThatModule => "bin/modules/thatModule.swf" mxmlc "bin/modules/thatModule.swf" do |t| addCommonTaskParameters(t) t.input = "src/project/modules/ThatModule.as" end Thanks.

• i integer does not +1 the 1st time

  - by Hwang

  I have a gallery where it will load an image after a previous image is loaded, so every time 'i' will +1 so that it could move to the next image. This code works fine on my other files, but I dunno why it doesn't work for the current file. Normally if I trace 'i' the correct will be 0,1,2,3,4,5,6... etc adding on till the limit, but this files its 'i' repeat the 1st number twice, only it continues to add 0,0,1,2,3,4,5,6...etc The code is completely the same with the other file I'm using, but I don't know why it just doesn't work here. The code does not seems to have any problem. Anyway i can work around this situation? private var i:uint=0; private function loadItem():void { if (i<myXMLList.length()) { loadedPic=myXMLList[i].thumbnails; galleryLoader = new Loader(); galleryLoader.load(new URLRequest(loadedPic)); galleryLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,picLoaded); } else { adjustImage(); } } private function picLoaded(event:Event):void { var bmp=new Bitmap(event.target.content.bitmapData); bmp.smoothing=true; bmpArray.push(bmp); imagesArray[i].addChild(bmp); i++; loadItem(); }

• Visual C++ 2010, rvalue reference bug?

  - by Sergey Shandar

  Is it a bug in Visual C++ 2010 or right behaviour? template<class T> T f(T const &r) { return r; } template<class T> T f(T &&r) { static_assert(false, "no way"); return r; } int main() { int y = 4; f(y); } I thought, the function f(T &&) should never be called but it's called with T = int &. The output: main.cpp(10): error C2338: no way main.cpp(17) : see reference to function template instantiation 'T f<int&>(T)' being compiled with [ T=int & ] Update 1 Do you know any C++x0 compiler as a reference? I've tried comeau online test-drive but could not compile r-value reference. Update 2 Workaround (using SFINAE): #include <boost/utility/enable_if.hpp> #include <boost/type_traits/is_reference.hpp> template<class T> T f(T &r) { return r; } template<class T> typename ::boost::disable_if< ::boost::is_reference<T>, T>::type f(T &&r) { static_assert(false, "no way"); return r; } int main() { int y = 4; f(y); // f(5); // generates "no way" error, as expected. }

• Why does my DIV clip its child DIV when jQuery moves it in IE?

  - by Ben Saufley

  I have two divs, both with position:absolute;, one inside the other. The parent isn't in a place where it can be set as position:relative without an extra layer of complexity (there are a lot of other elements around it that I'd have to account for to put it where it needs to be, which is at the very top of the page, over everything). The child element is made to stick off the bottom of the parent. In Chrome, Safari, Firefox, it all works splendidly. In IE, it works until jQuery moves the parent element - at which point the parent element clips the child, so you can barely see the top of the child. I feel like I've read about this, about IE clipping child elements, but I can't seem to find an answer that applies to my case. It's pretty simple, basically: <div id="parent" style="position:absolute;top:0;left:0;"> [content] <div id="tab" style="position:absolute;bottom:-30px;left:0;width:64px;height:32px;background-image:(...);"></div> </div> <script> $(document).ready( function() { $("#tab").click(function() { $("#parent").animate({"top":"-50px"},300); }); }); </script>

• Create a variable which is named depending on an ID number?

  - by gray

  Is there any way to create a variable, and add an ID to the end of the actual variable name? I have a variable called 'gauge', used to create a new Gauge object: var gauge = new Gauge(target).setOptions(opts); I want to add an ID to the variable, so something like: var gauge+id = new Gauge(target).setOptions(opts); It's because I'm creating a number of these objects, and have a specific ID already for each one, which I want to attach to the gauge object if possible? All my code for this function is below, if it gives you a better idea of what i need to do: function go(id, votes) { var val = $('#votes_'+id).text(); var target = document.getElementById('foo_'+id); // your canvas element var gauge = new Gauge(target).setOptions(opts); // create sexy gauge! gauge.maxValue = 100; // set max gauge value gauge.animationSpeed = 20; // set animation speed (32 is default value) var a=votes+0.5; gauge.set(val); // set actual value } My main problem arises on the last line. It says gauge.set(val), and it only sets the last object, ignoring all the other ones...

• stripping random number with substr problem

  - by Jim

  Using a random number to be included with another character. Then I want to strip out the random number and just leave the other character. I have this code that generates the random number (8 characters long) consistently. If you hit your refresh button multiple times, the “ID” field disappears even though the “Random Number” plus “ID” are still there. Not sure what is happening to the random number on refresh in the substr function. This is the code: // Begin Create Random ID Code ///////////////////////////////////////// function gRanStr1() { $length1 = 8; $characters = “0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ”; for ($p = 0; $p < $length1; $p++) { $lcrs1 .= $characters[mt_rand(0, strlen($characters)-1)]; } $lcrs9 = str_replace(' ', '', $lcrs9); return $lcrs1; } // End Create Random ID Code ///////////////////////////////////////// // Begin Decode Random ID Code ///////////////////////////////////////// $TrkR99 = "c"; $ResHeadID = gRanStr1() . $TrkR99; $ResHeadID = preg_replace('/[\s]+/',' ',$ResHeadID); echo "”; echo $ResHeadID . ” = echo of Random Number plus ID“; for($i=0; $i if ($ResHeadID == "") { ""; } else { $ResHeadID = preg_replace('/[\s]+/',' ',$ResHeadID); $TrkRa1 = substr($ResHeadID, $Index1 + 8, 1); } $dTrkRes = $TrkRa1; echo $TrkRa1 .

• WPML is not detecting Wordpress custom post types

  - by janoChen

  I learned how to make custom post types with the following tutorial: http://sixrevisions.com/wordpress/wordpress-custom-post-types-guide/ It basically consist in adding this code to function.php: add_action( 'init', 'create_events' ); function create_events() { $labels = array( 'name' => _x('Events', 'post type general name'), 'singular_name' => _x('Event', 'post type singular name'), 'add_new' => _x('Add New', 'Event'), 'add_new_item' => __('Add New Event'), 'edit_item' => __('Edit Event'), 'new_item' => __('New Event'), 'view_item' => __('View Event'), 'search_items' => __('Search Events'), 'not_found' => __('No Events found'), 'not_found_in_trash' => __('No Events found in Trash'), 'parent_item_colon' => '' ); $supports = array('title', 'editor', 'custom-fields', 'revisions', 'excerpt'); register_post_type( 'event', array( 'labels' => $labels, 'public' => true, 'supports' => $supports ) ); } The WPML plugin help you to translate posts to different langauges. But this option doesn't appear in the custom post types. Any suggestions?

• std::stringstream GCC Abnormal Behavior

  - by FlorianZ

  I have a very interesting problem with compiling a short little program on a Mac (GCC 4.2). The function below would only stream chars or strings into the stringstream, but not anything else (int, double, float, etc.) In fact, the fail flag is set if I attempt to convert for example an int into a string. However, removing the preprocessor flag: _GLIBCXX_DEBUG=1, which is set by default in XCode for the debug mode, will yield the desired results / correct behavior. Here is the simple function I am talking about. value is template variable of type T. Tested for int, double, float (not working), char and strings (working). template < typename T > const std::string Attribute<T>::getValueAsString() const { std::ostringstream stringValue; stringValue << value; return stringValue.str(); } Any ideas what I am doing wrong, why this doesn't work, or what the preprocessor flag does to make this not work anymore? Thanks!

  How can I echo this javascript if the php error messages is called? I have an error message setting that when a user misses his username or password it triggers an error message. The php error message is called by a php code. Here is the code: <?php echo showmessage($msg) ?> I have an alert message in javascript that when called it will make a javascript css pop up alert box. IF the javascript code is present it will show the alert box right away after reload. Here is code: <script type="text/javascript"> $(document).ready(function () { jqxAlert.alert('Alert Message'); }) </script> How can I incorporate so that when the php echo message comes up it will trigger the javscript alert message. I was trying an if in php, so something like this code: if ( showmessage($msg) ) { <script type="text/javascript"> $(document).ready(function () { jqxAlert.alert('Alert Message'); }) </script> } How can I echo my javascript message on the php call?

• Check if DateTime in specific range

  - by katit

  Need to check if DateTime is in specific range. I think I need to calculate knowing YEAR first and last date of DST time in this year. How would I figure "Sunday of week 2 of March" date? From 1/1/2007 12:00:00 AM to 12/31/9999 12:00:00 AM Begins at 2:00 AM on Sunday of week 2 of March Ends at 2:00 AM on Sunday of week 1 of November For example, I need to check if 11/21/2011 is between Sunday of week 2 in March and Sunday of week 1 of November - answer should be NO If I pass 8/8/2011 - answer should be yes. Basically, I need to write function to check if my date belongs to daylight savings time. My only idea so far is to write loops to find 2nd week for example. So, I would loop from Day 1 in March until I hit Sunday second time. Same thing I would loop (increment days by 1) from day 1 of November until I hit Sunday first time. In another words, I need function to check if input data is in Daylight Savings time period. Time period defined by constraint above. P.S. I can't use TimeZoneInfo since it's in Silverlight P.P.S I can't use DateTime.IsDaylightSavingsTime as I don't have times with kind "local"

  I have an array of double arrays, they are within a specified time window (8am-5pm), and are in order of last created over a period of several days. They are all timestamped and as such I have access to all C# DateTime methods. I then have a different iterative function that goes in the same order of the array of double arrays, however it isn't within a specified time window, it's 24/7. I want to access from this iterative function, the appropriate double array from the one within the window. Let's say that it's 4:30PM on DayOfYear 52, I'd like to access the last double array less than or equal to 4:30PM on DayOfYear 52. I'd expect the same double array if the time were 12:30AM on DayOfYear 53. However, if it were 9:00 AM of DayOfYear 53, well then I'd expect it to return something from the DayOfYear 53, less than or equal to 9:00AM. I think you get the idea. So I'm a having a bit of trouble grokking how to do this. Is anyone willing to offer a starting point or how they'd approach it? Edit: It is not a literal double[][], it is exactly as Anthony Pegram says: Dictionary<DateTime, double[]>

• jquery : ul, li parent multiple child sub-child toggling

  - by user360826

  hello, my main question is as follows: how to show only the first subchild of a ul or li upon clicking the enclosing parent. eg: <ul> Grandparent <li> Child1 <li> Grandchild11</li></li> <li> Child2 <li>GrandChild21</li><li>grandchild22</li></li> </ul> so, for example I would like something to the effect of <script> $('ul').click(function(){ $('ul').children('first li').toggle() }); $('li').click(function(){ $('li').children('first li').toggle() }); </script> meaning: when i click ul, i only see the first child node (child1 and child2 will be shown, but not the grandchildren). when i click child1 or child2 i see the respective grandchild. grandchild is not shown upon clicking grandparent, only upon clicking child1 or child2. i know i am reinventing the wheel of some pre-coded solution, but any help would be largely appreciated!
