  • 1180: Call to a possibly undefined method addEventListener

    - by Chris
    I'm going through some AS3 training, but I'm getting a weird error... I'm trying to add an event listener to the end of a motion tween in AS. I've created a tween, highlighted the frames, right clicked and copied the tween as AS and pasted it into the movie clip (I think there's a better way to do this, but I'm not sure what it is...) When I try to add the listener to the end of that code, I get the error. Here's my code. import fl.motion.AnimatorFactory; import fl.motion.MotionBase; import fl.motion.Motion; import flash.filters.*; import flash.geom.Point; import fl.motion.MotionEvent; import fl.events.*; var __motion_Enemy_3:MotionBase; if(__motion_Enemy_3 == null) { __motion_Enemy_3 = new Motion(); __motion_Enemy_3.duration = 30; // Call overrideTargetTransform to prevent the scale, skew, // or rotation values from being made relative to the target // object's original transform. // __motion_Enemy_3.overrideTargetTransform(); // The following calls to addPropertyArray assign data values // for each tweened property.

Can please some one review it and give me some Ideas, how it could be written clearer for everybody? /** * Converts arrays or SimpleXML-Objects into an XML-String * @params mixed Accepts an array or xml string with data to Post * @params integer DO NOT PROVIDE. Internal Usage for recursion only */ private function mixedDataToXML($data, $level = 1) { if(!$data){ return FALSE; } if(is_array($data)) { $xml = ''; if ($level==1) { $xml .= '<?xml version="1.0" encoding="ISO-8859-1"?>'."\n"; } foreach ($data as $key => $value) { $key = strtolower($key); if (is_array($value)) { $multi_tags = false; foreach($value as $key2=>$value2) { if (is_array($value2)) { $xml .= str_repeat("\t",$level)."<$key>\n"; $xml .= $this->mixedDataToXML($value2, $level+1); $xml .= str_repeat("\t",$level)."</$key>\n"; $multi_tags = true; } else { if (trim($value2)!='') { if (htmlspecialchars($value2)!=$value2) { $xml .= str_repeat("\t",$level).

  • Source code for Top on Wince

    - by Chris
    I want to be able to get the current CPU usage in a C++ program running under Wince. I found this link that states where the source code is but I cannot find it in my platform builder installation - I expect this is because it isn't the Windows Automotive platform. Does anyone know where I can find this source code or (even better) know how I can get this information directly? i.e. what DLL / function calls to make etc.

  • div popup inside td

    - by sims
    I have a table with a bunch of cells. (No way! Amazing! :P) Some of the cells have a small div that when you put your mouse over, it gets bigger so you can read all the text. This works well and all. However, since html elements that come later in the document have a higher z-index, when the div gets bigger it is underneath the other divs in the other cells. Some html code: <table> <tr> <td> limited info <div style="position: relative;"> <div style="position: absolute; top: 0; left: 0; width: 1em; height: 1em;" onmouseover="tooltipshow(this)" onmouseout="tooltiphide(this)"> informative long text is here </div> </div> </td> <td> some short info <div style="position: relative;"> <div style="position: absolute; top: 0; left: 0; width: 1em; height: 1em;" onmouseover="tooltipshow(this)" onmouseout="tooltiphide(this)"> longer explanation about what is really going on that covers the div up there ^^^. darn! </div> </div> </td> </tr> </table> Some js code: function tooltipshow(obj) { obj.style.width = '30em'; obj.style.zIndex = '100'; } function tooltiphide(obj) { obj.style.width = '1em'; obj.style.zIndex = '20'; } It doesn't matter if I set z-index dynamically to something higher onmouseover. It's like z-index has no affect. I think it has something to do with the table. I've tested this in FF3. When I'm feeling particularly macho, I'll test it in IE.

  • How do I reference sqlite db column to use in update statement

    - by user244190
    I am trying to update a datetime column in an android sqlite db to use international date format (yyyy-mm-dd) instead of the current format (mm/dd/yyyy). I want to use the sqlite date() function to reformat the current value of the column. I thought it would be as simple as the following: update tblename set thedate = date(thedate) but the above does not work. How would i write the sql statement to accomplish this? thanks patrick

  • Unable to get index from jQuery UI slider range

    - by Phil.Wheeler
    I'm having a hell of a time trying to get (what I thought was) a simple index from a collection of multiple sliders. The HTML is as follows: <div id="left-values" class="line"> <span id="l1" style="padding: 0 1.8em;">0</span> <span id="l2" style="padding: 0 1.8em;">0</span> <span id="l3" style="padding: 0 1.8em;">0</span> <span id="l4" style="padding: 0 1.8em;">0</span> <span id="l5" style="padding: 0 1.8em;">0</span> <span id="l6" style="padding: 0 1.8em;">0</span> <span id="l7" style="padding: 0 1.8em;">0</span> <span id="l8" style="padding: 0 1.8em;">0</span> </div> And the jQuery code is: // setup audiometry sliders $("#eq > span").each(function (e) { // read initial values from markup and remove that var value = parseInt($(this).text()); // var index = $(this).index; <- this didn't work. $(this).empty(); $(this).slider({ value: value, slide: function (event, ui) { //console.log($(this).attr('id')); <- neither did this. //console.log(index); $('#left-values span:first').text(ui.value); } }) }); The problem is that jQuery UI - when creating a slider - replaces the existing HTML with its own markup. This includes any ID values and, for whatever reason, I can't get the index for a given slider to surface either. So I'm running out of ideas.

  • Windows7 Installer takes priority how to move it back during installation using C#?

    I've a custom Action on Deployment project of .NET Applicaiton, which contains custom dialogbox to enter certain parameters, on invalid parameters I've shown MessageBox.Show - but its being hide by installer window, I tried windows forms too with Activate, TopMost, Focus,bring2front, etc serveral options but it comes by default behind the windows installer window and due to this user is not able to identify why installing process is not finishing - because actually its waiting for user to read the MessageBox and press OK. I've tried to implement IWin32Window with the handler of MsiExec Process, and shown the Messagebox but still its not working, anyone has idea ???

  • Open source C program with little requirements and at least 2MB binary size.

    - by max
    Hi, I'm developing a operating system and I need a test program (function of any kind) to test certain internal features. I cannot find any appropriate program to do this job. Probably one of you knows one. The program should be open source, written in C with very little user library usage (only file IO, pthreads, stdio, stdlib preferred) and must have a binary size of at least 2MB. Thanks for any suggestions.

  • Drop down table and jquery

    - by Marcelo
    Hi, I'm trying to make a drop down table using jQuery, with a similar code like here: (from the topic: Conditional simple drop down list?) <body> <div id="myQuestions"> <select id="QuestionOptions"> <option value="A">Question A</option> <option value="B">Question B</option> </select> </div> <div id="myAnswers"> <div id="A" style="display: none;"> <div id="QuestionC"> <p>Here is an example question C.</p> </div> <div id="QuestionD"> <select id="QuestionOptionsD"> <option value="G">Question G</option> <option value="H">Question H</option> </select> </div> </div> <div id="B" style="display: none;"> <div id="QuestionE"> <p>Here is an example question E.</p> </div> <div id="QuestionF"> <select id="QuestionOptionsF"> <option value="I">Question I</option> <option value="J">Question J</option> </select> </div> </div> </div> And the jQuery part $(function () { $('#QuestionOptions').change(function () { $('#myAnswers > div').hide(); $('#myAnswers').find('#' + $(this).val()).show(); }); }); My problem is, when I finish to table the part of "myQuestions", and start to table the part of "myAnswers", the dynamic part of the table doesn't work. In this case, the myAnswers part won't be hidden, it'll be shown since the beginning. I tried to put everything in one table, then I tried to create a different table for myQuestions, then another table for myAnswers and it didn't work. Does anyone know where am I mistaking ? Sorry for any mistake in English, I'm not a native speaker. Thanks in advance.
