• C# cross thread dialogue co-operation

  - by John Attridge

  K I am looking at a primarily single thread windows forms application in 3.0. Recently my boss had a progress dialogue added on a separate thread so the user would see some activity when the main thread went away and did some heavy duty work and locked out the GUI. The above works fine unless the user switches applications or minimizes as the progress form sits top most and will not disappear with the main application. This is not so bad if there are lots of little operations as the event structure of the main form catches up with its events when it gets time so minimized and active flags can be checked and thus the dialog thread can hide or show itself accordingly. But if a long running sql operation kicks off then no events fire. I have tried intercepting the WndProc command but this also appears queued when a long running sql operation is executing. I have also tried picking up the processes, finding the current app and checking various memory values isiconic and the like inside the progress thread but until the sql operation finishes none of these get updated. Removing the topmost causes the dialog to disappear when another app activates but if the main app is then brought back it does not appear again. So I need a way to find out if the other thread is minimized or no longer active that does not involve querying the actual thread as that locks until the sql operation finishes. Now I know that this is not the best way to write this and it would be better to have all the heavy processing on separate threads leaving the GUI free but as this is a huge ancient legacy app the time to re-write in that fashion will not be provided so I have to work with what I have got. Any help is appreciated

• Overlapping audio in IE when I show/hide videos

  - by user1062448

  I have a thumbnail list with links to individual videos. Everything works fine in all browsers but IE. In IE, if I start a video and (without slicking pause or stop) click on the thumbnail for the next video, the audio continues playing. In other words, the audio for both videos plays at once. Any suggestions? HTML: <ul class="videoButtons"> <li><a class="vidButton" href="javascript:void(0)" id="1" ><img src="images/videoPics/vid1Thumb.jpg" /><br />video title</a></li> <li><a class="vidButton" href="javascript:void(0)" id="2" ><img src="images/videoPics/vid2Thumb.jpg" /><br />video title</a></li> <li><a class="vidButton" href="javascript:void(0)" id="3" ><img src="images/videoPics/vid3Thumb.jpg" /><br />video title</a></li> </ul> <div class="box" id="video1"> <!--flv embedded object - FLVPlayer--> </div> <div class="box" id="video2"> <!--flv embedded object - FLVPlayer1--> </div> <div class="box" id="video3"> <!--flv embedded object - FLVPlayer2--> </div> Show/Hide code: $(".vidButton").click(function() { var buttonID = $(this).attr('id'); // get ID of the button clicked var video = $('#'+'video'+buttonID); // add ID number to video $('.box').hide(); // hide all other divs video.fadeTo("slow", 1); // show video }); }); // video objects swfobject.registerObject("FLVPlayer"); swfobject.registerObject("FLVPlayer1"); swfobject.registerObject("FLVPlayer2");

• How to clean up my code

  - by simion

  Being new to this i realy am trying to learn how to keep code as simple as possible, whilst doing the job its supposed to. The question i have done is from project eulur, it says Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... Find the sum of all the even-valued terms in the sequence which do not exceed four million. Here is my code below, i was wondering what the best way of simplifying this would be, for a start removing all of the .get(list.length()-1 )..... stuff would be a good start if possible but i dont really no how to? Thanks public long fibb() { ArrayList<Integer> list = new ArrayList<Integer>(); list.add(1); list.add(2); while((list.get(list.size() - 1) + (list.get(list.size() - 2)) < 4000000)){ list.add((list.get(list.size()-1)) + (list.get(list.size() - 2))); } long value = 0; for(int i = 0; i < list.size(); i++){ if(list.get(i) % 2 == 0){ value += list.get(i); } } return value; }

• Choosing right control for list of items

  - by prostynick

  I am new to WPF and MVVM. In my ViewModel I have collection of items, for example: class Item { string Title {get; set;} string Description {get; set;} } I would like to create a view, so at the beginning I would have: Title1 Title2 Title3 If user click on one of title it will expand to show description, eg: Title1 Description1 Title2 Title3 If user click on other title, there will be two expanded items: Title1 Description1 Title2 Description2 Title3 This is probably very similar to Expander control and maybe I could use it, but I am doing it other way, to learn something new. What control should I use for this purpose? Should that be ItemsControl or maybe ListBox? I imagine, that if I use ItemsControl, I should probably extend my Item class to have something like bool IsExpanded and bind UI item visibility to that value. But maybe I could use ListBox and somehow bind UI item visibility to... Yeah, to what? :) How could I do such a simple thing?

• Line by Line explanation of "Javascript: Good Parts" example?

  - by Matrym

  I'm reading "Javascript: The Good Parts" and am totally baffled by what's really going on here. A more detailed and/or simplified explanation would be greatly appreciated. // BAD EXAMPLE // Make a function that assigns event handler functions to an array of nodes the wrong way. // When you click on a node, an alert box is supposed to display the ordinal of the node. // But it always displays the number of nodes instead. var add_the_handlers = function (nodes) { var i; for (i = 0; i < nodes.length; i += 1) { nodes[i].onclick = function (e) { alert(i); } } }; // END BAD EXAMPLE The add_the_handlers function was intended to give each handler a unique number (i). It fails because the handler functions are bound to the variable i, not the value of the variable i at the time the function was made: // BETTER EXAMPLE // Make a function that assigns event handler functions to an array of nodes the right way. // When you click on a node, an alert box will display the ordinal of the node. var add_the_handlers = function (nodes) { var i; for (i = 0; i < nodes.length; i += 1) { nodes[i].onclick = function (i) { return function (e) { alert(i); }; }(i); } }; Now, instead of assigning a function to onclick, we define a function and immediately invoke it, passing in i. That function will return an event handler function that is bound to the value of i that was passed in, not to the i defined in add_the_handlers. That returned function is assigned to onclick.

• jQuery adding a function to a link question

  - by wali

  Hello all, I have a dynamically created table which in the last <td> there is a hidden <div> which is shown when the user hovers over a link in the <td>. That all works fine but there are several links in the div that I want to fire a function based on the id of the link concat'd with an string captured from a <td> from the parent row. I can capture the the variables I need from the id and <td> but something is wrong with the click function I have created. I monitored the function in FireBug and the function appears to be firing on all of the links instead of the one that is clicked. Here is my working code: function fixLink() { $('a.batchMatchLink').click( function() { var r = $(this).parent().parent().parent().parent().parent(); var x = $(this).attr("id"); var a = $(r).find('td:nth-child(6)').text(); var st = x + "." + a; fireLink(st); } ); } function fireLink(st) { $.ajax({ type: "POST", url: "AjaxWcf.svc/MatchBatch", contentType: "application/json; charset=utf-8", data: st, dataType: "json", success: function(msg) { alert("Entry has been updated"); }, error: AjaxFailed }); Why are all of the links firing? Thanks!!!

• How can I convert a byte array into a double and back?

  - by user350005

  For converting a byte array to a double I found this: //convert 8 byte array to double int start=0;//??? int i = 0; int len = 8; int cnt = 0; byte[] tmp = new byte[len]; for (i = start; i < (start + len); i++) { tmp[cnt] = arr[i]; //System.out.println(java.lang.Byte.toString(arr[i]) + " " + i); cnt++; } long accum = 0; i = 0; for ( int shiftBy = 0; shiftBy < 64; shiftBy += 8 ) { accum |= ( (long)( tmp[i] & 0xff ) ) << shiftBy; i++; } return Double.longBitsToDouble(accum); But I could not find anything which would convert a double into a byte array.

• Job queueing and execute Mechanism

  - by Calm Storm

  In my webservice all method calls submits jobs to a queue. Basically these operations take long time to execute, so all these operations submit a Job to a queue and return a status saying "Submitted". Then the client keeps polling using another service method to check for the status of the job. Presently, what I do is create my own Queue, Job classes that are Serializable and persist these jobs (i.e, their serialized byte stream format) into the database. So an UpdateLogistics operation just queues up a "UpdateLogisticsJob" to the queue and returns. I have written my own JobExecutor which wakes up every N seconds, scans the database table for any existing jobs, and executes them. Note the jobs have to persisted because these jobs have to survive app-server crashes. This was done a long time ago, and I used bespoke classes for my Queues, Jobs, Executors etc. But now, I would like to know has someone done something similar before? In particular, Are there frameworks available for this ? Something in Spring/Apache etc Any framework that is easy to adapt/debug and plays well along with libraries like Spring will be great.

• Search Box/Transition won't work in Firefox

  - by user2522488

  I disabled the search box on IE, because IE kept centering it over the navigation. It works in Chrome, I'm not sure about opera (and I'm not sure if I care) but it won't work in Firefox. The ease-out timing works in Firefox, but nothing else really works. I've tried other things to work around the issue, but every time I try something different, the search box's positioning gets thrown off. If you look at it in Firefox, it looks fine-- until you click on it to search. http://kissoff.weebly.com/ You can see what the search box is supposed to do if you look at it and click on it in Chrome. I'm sure the positioning is off, I'm not sure (I'm new to css). Any help is appreciated. #search {} #search input[type="text"] { background: url(search-white.png) no-repeat 10px 6px #fcfcfc; border: 1px solid #d1d1d1; position: fixed; margin-left: 350px; margin-right: 0px; margin-top: 0px; color: #bebebe; width: 150px; padding: 6px 15px 6px 35px; -webkit-border-radius: 20px; -moz-border-radius: 20px; border-radius: 20px; text-shadow: 0 2px 3px rgba(0, 0, 0, 0.1); -webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; -moz-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; box-shadow: 0 1px 3px rgba(0, 0, 0, 0.15) inset; -webkit-transition: all 0.7s ease 0s; -moz-transition: all 0.7s ease 0s; -o-transition: all 0.7s ease 0s; transition: all 0.7s ease 0s; float: right; } #search input[type="text"]:focus { width: 200px; }

• Multiple forms + HAML + jQuery + Javascript submit

  - by Jay Godse

  Hi. I have a HAML page that lists some links to delete "things" that looks like this %div %a.form_submit Delete Thing 1 %form{:href=>"#", :id=>'comment_1', :method=>'post', :action=>'/thing/delete'} %input{:type=>'hidden', :name=>'thingid', :value=>'1'} %input{:type=>'submit', style='display:none'} %div %a.form_submit Delete Thing 22 %form{:href=>"#", :id=>'comment_22', :method=>'post', :action=>'/thing/delete'} %input{:type=>'hidden', :name=>'thingid', :value=>'22'} %input{:type=>'submit', style='display:none'} The intention is to have a link "Delete XX" which will delete something specific. A page could have a number of these links, and each link is for a specific "thing". I also have a piece of (unobtrusive) jQuery javascript that adds a click handler to each form as follows: $('a.form_submit').click(function(event) { $('form').submit(); event.preventDefauilt(); }); This works when there is one form on a page. However, if I have more than one form on a page, how do I ensure that clicking "Delete Thing 1" will trigger a submit() event only on the form with id='comment_1'?

• Why does applying this gradient style break my silverlight app ?

  - by Robotsushi

  I am having some issues with applying a gradient to a RadButton. I have a gradient definition in my styles resource dictionairy like so : <LinearGradientBrush x:Key="GridView_HeaderBackground" EndPoint="0.5,1" StartPoint="0.5,0"> <GradientStop Color="#FF5B5B5B" Offset="1"/> <GradientStop Color="#FF868686"/> <GradientStop Color="#FF4F4F4F" Offset="0.42"/> <GradientStop Color="#FF0E0E0E" Offset="0.43"/> </LinearGradientBrush> When i apply this gradient directly to the background of a RadButton everything works. Here is the button and the template definition: Button <telerik:RadButton Margin="5,10,5,0" Click="RadButton_Click" Tag="30" Content="30 Days" Style="{StaticResource SliderButton}" Background="{StaticResource GridView_HeaderBackground}" /> Template: <!-- Style Template for Slider RadButton --> <Style x:Key="SliderButton" TargetType="telerik:RadButton"> <Setter Property="Height" Value="30" /> <Setter Property="Foreground" Value="#FFFFFF" /> <Setter Property="BorderThickness" Value="0" /> <Setter Property="Margin" Value="5,2" /> </Style> However when applying this gradient in the resource dictionary, my application will not load it simply gets to the silverlight loading screen and then never proceeds Here is the button and template which breaks my app. Button: <telerik:RadButton Margin="5,10,5,0" Click="RadButton_Click" Tag="30" Content="30 Days" Style="{StaticResource SliderButton}" /> Template: <!-- Style Template for Slider RadButton --> <Style x:Key="SliderButton" TargetType="telerik:RadButton"> <Setter Property="Background" Value="{StaticResource GridView_HeaderBackground}" /> <Setter Property="Height" Value="30" /> <Setter Property="Foreground" Value="#FFFFFF" /> <Setter Property="BorderThickness" Value="0" /> <Setter Property="Margin" Value="5,2" /> </Style> When i observe the js error console in google chrome i notice the following error is produced: "Cannot find a resource with the name/key ResourceWrapper"

• Finding patterns of failure in a Unit Test

  - by Pekka

  I'm new to Unit Testing, and I'm only getting into the routine of building test suites. I have what is going to be a rather large project that I want to build tests for from the start. I'm trying to figure out general strategies and patterns for building test suites. When you look at a class, many tests come to you obviously due to the nature of the class. Say for a "user account" class with basic CRUD operations, being related to a database table, we will want to test - well, the CRUD. creating an object and seeing whether it exists query its properties change some properties change some properties to incorrect values and delete it again. As for how to break things, there are "fail" tests common to most CRUD classes like: Invalid input data types A number as the ID key that exceeds the range of the chosen data type Input in an incorrect character encoding Input that is too long And so on and so on. For a unit test concerned with file operations, the list of "breaking things" could be Invalid characters in file name File name too long File name uses incorrect protocol or path I'm pretty sure similar patterns - applicable beyond the unit test one is currently working on - can be found for most units that are being tested. Now my question is: Am I correct in seeing such "breaking patterns"? Or am I getting something completely wrong about Unit testing, and if I did it right, this wouldn't be an issue at all? Is Unit Testing as a process of finding as many ways to break the unit as possible the right way to go? If I am correct: Are there existing definitions, lists, cheat sheets for such patterns? Are there any provisions (mainly in PHPUnit, as that's the framework I'm working in) to automate such patterns? Is there any assistance - in the form of check lists, or software - to aid in writing complete tests?

• Why does Go not seem to recognize size_t in a C header file?

  - by Graeme Perrow

  I am trying to write a go library that will act as a front-end for a C library. If one of my C structures contains a size_t, I get compilation errors. AFAIK size_t is a built-in C type, so why wouldn't go recognize it? My header file looks like: typedef struct mystruct { char * buffer; size_t buffer_size; size_t * length; } mystruct; and the errors I'm getting are: gcc failed: In file included from <stdin>:5: mydll.h:4: error: expected specifier-qualifier-list before 'size_t' on input: typedef struct { char *p; int n; } _GoString_; _GoString_ GoString(char *p); char *CString(_GoString_); #include "mydll.h" I've even tried adding either of // typedef unsigned long size_t or // #define size_t unsigned long in the .go file before the // #include, and then I get "gcc produced no output". I have seen these questions, and looked over the example with no success.

• Have a clickable button on top of a combobox in WPF

  - by Travyguy9

  I can get a button to appear and be clickable in the drop down list of a combo box, but I cannot get the selected combo box item (the drop list is closed) to have the button be clickable. It always skips the button click and just opens the drop down list. I basically want the Button_Click event handler that I setup to be called once it is clicked. Here is my sample combo box that shows the button but is not clickable once it is in the selected item: <ComboBox x:Name="MyCombo" Width="200" Height="30" ItemsSource="{Binding ListCombo}"> <ComboBox.Resources> <DataTemplate DataType="{x:Type local:ComboItemClass}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=SampleText}" Width="120" /> <Button Width="20" Content="..." Click="Button_Click"/> </StackPanel> </DataTemplate> </ComboBox.Resources> </ComboBox>

• Migrating Ajax web application to web socket

  - by Bastan

  Hi, I think i'm just missing a little detail that is preventing me from seeing the whole picture. I have a web application which use ajax request every x time to update client with new information or tasks. I also have a long running process on the server which is a java computation engine. I would like this engine to send update to the client. I am wondering how to migrate my web app to using websocket. Probably phpwebsocket or similar. Can my server 'decide' to send information to a specific client? It seems possible looking at the php-websocket. Can my java backend long process use the websocket server to send notification to a specific client. How? well I can say that my java app could use a class that could send over websocket instead of http. But how the websocket server knows to which client to send the 'info'. I am puzzle by all this. Any document that explain this in more details? It seems that the websocket could create an instance of my web application. Thanks

• Refresh page using cache

  - by cbh

  I am trying to refresh a page, but WANT to use the cache and can't figure out how to do this. There are two situations: If I click in the URL bar and hit enter (or visit the page from somewhere else) it reloads the page/images from the cache. GREAT! If I click on the refresh button or use Javascript to refresh the page it grabs all the images again and takes forever. NOT GREAT! I've tried: top.location.reload(false); and top.location.reload(true); (I'm sending this from in an iFrame) and neither used the cache. I'm avoiding using location so it doesn't end up in the browser history twice. Question: How do I reload the page using the cached images? Is there a different javascript function or is this a mod_expires issue? Thanks for any help in advance! EDIT: (info from chrome: developer tools) When navigating to the page I get "From Cache" for all images When refreshing page I get "304 - Not Modified" for all images (and it takes the time to download each)

• Letting user carry on after three attempts

  - by sMilbz

  In my spelling game there is a grid that is populated with words. The words are hidden and the aim of the game is to spell the word that is highlighted with the aid of a sound and a picture. To highlight a word you press the "next" button. At the moment if you spell the word correctly it says "well done" and you can advance to the next word, but if you spell it incorrectly you have to keep attempting the word until it is complete. As the game is designed for children I do not think this is the best approach, so I would like to make it so you can advance after 3 incorrect attempts. I have played around with the script so much trying to put counters on incorrect attempts and then making the button active but cannot seem to get it to work. Can someone please help me? Here is the script for the button var noExist = $('td[data-word=' + listOfWords[rndWord].name + ']').hasClass('wordglow2'); if (noExist) { $('.minibutton').click(); } else { $('.minibutton').click('disable'); $("#mysoundclip").attr('src', listOfWords[rndWord].audio); audio.play(); $("#mypic").attr('src', listOfWords[rndWord].pic); pic.show(); } }); "wordglow2" is the style applied if the word is spelt correctly. Here is a fiddle to help understand... http://jsfiddle.net/smilburn/ZAfVZ/4/

• live image edit , and crop

  - by 422

  I was just thinking, which is always dangerous. We use Valums Image uploader. Aside from that, I am looking for an inline image editor, but with a difference. User uploads an image ( lets say 800 x 600 ) Our system wants to see the image ( 170 x 32 ) now I know we can use php to resize images. But I was thinking, does anyone know of a system, where we can display the image, and user can scale, and crop image ( with say a predefined overlay ) By that they scale down to nearest acceptable size, and then click crop tool, which shows a div overlay with say 70% transparency that they can drag over the image, and then click crop. So image is cropped to exact size we need, then can save . I am sure I have seen some jquery stuff done like this, just cannot for life of me find it. Essentialy, we would like to offer a simple client side image processor, thats lightweight, and then the ability to save what they did . Sorry no code to show, as its more of a request. Regards

• howto catch jQuery for multiple links but not all

  - by user247245

  I'm trying to dig into jQuery but would like some feedback on how to do things the best way, I have a list with items, which each contains a hidden div that should show upon click on it's parent, list div:ed item1 with link hidden div div:ed item2 with link hidden div .. My current solution is to trace the calling link by it's id and then reusing that ID for showing the correct hidden one: $(document).ready(function() { //jQ should only trigger on links with id="cmLinkINT" $("a").click(function() { //see if it's a comment request. var s = $(this).attr("id"); if (s.indexOf('cmLink') != -1) { //ok, it was a 'show'-link, get the id.. var j = s.substring(6); //ok, now I have the id i want to show (detailsINT) return false; } }); }); What's not clear to me is the best approach, Should I use id for requesting a or trace the id of the parent div. How to avoid that the code triggers on any link? Class? Thankful for any feedback, regards //t

  - by kpomka

  Hi there Im trying to do a few things with jQuery validation plugin and seems stuck on one place. Here is some code: <script type="text/javascript"> $(document).ready(function(){ $('#myform').validate(); $('#email').rules('add', {required: true, messages: {required: 'email is required'}} ); $('#phone').rules('add', {required: true, messages: {required: 'phone is required'}} ); $('#validate').click(function(){ $('#result').text($('#myform').validate().form()); return false; }); }); </script> <form id="myform"> <div>email:<input type="text" id="email" /></div> <div>phone:<input type="text" id="phone" /></div> <div id="result"></div> <input id="valdate" type="image" src="images/submit.png" /> </form> As a result i keep getting a wrong error message. If i click on submit button 'phone is required' is shown near email input and 'email is required' isnt shown at all. Whats wrong with this code ?
