  • Server -> Desktop Push API

    - by Rich Anderson
    Hi I am looking for solution which can push automatically a certain event (let's say RSS message) realtime to a desktop user. A toolbar app or a desktop (growl like) will be super for this push. I have looked at few options but cannot find much info on these kind of apps. I have looked at conduit - it sucks as there is lot of other fancy options which I am not interested in offering to users. Please let me know. Thanks.

  • jQuery('body').text() gives different answers in different browsers

    - by Charles Anderson
    My HTML looks like this: <html> <head> <title>Test</title> <script type="text/javascript" src="jQuery.js"></script> <script type="text/javascript"> function init() { var text = jQuery('body').text(); alert('length = ' + text.length); } </script> </head> <body onload="init()">0123456789</body> </html> When I load this in Firefox, the length is reported as 10. However, in Chrome it's 11 because it thinks there's a linefeed after the '9'. In IE it's also 11, but the last character is an escape. Meanwhile, Opera thinks there are 12 characters, with the last two being CR LF. If I change the body element to include a span: <body onload="init()"><span>0123456789</span></body> and the jQuery call to: var text = jQuery('body span').text(); then all the browsers agree that the length is 10. Clearly it's the body element that's causing the issue, but can anyone explain exactly why this is happening? I'm particularly surprised because the excellent jQuery is normally browser-independent.

  • How can I prevent a ToggleButton from being Toggled without setting IsEnabled=False

    - by Bryan Anderson
    I have a list of ToggleButtons being used as the ItemTemplate in a ListBox similar to this answer using the MultiSelect mode of the Listbox. However I need to make sure at least one item is always selected. I can get the proper behavior from the ListBox by just adding an item back into the ListBox's SelectedItems collection on the ListBox.SelectionChanged event but my ToggleButton still moves out of its toggled state so I think I need to stop it earlier in the process. I would like to do it without setting IsEnabled="False" on the last button Selected because I'd prefer to stay with the Enabled visual style without having to redo my button templates. Any ideas?

  • Require Integer Value not Memory Address whilst avoiding Invalid receiver type compiler warning

    - by Dave Anderson
    I have the following code; int days = [[SettingsUtils daysToRetainHistory] intValue]; [retainHistory setText:[NSString stringWithFormat:@"Days to retain History: %d", days]]; [daysToRetainHistory setValue:days animated:NO]; where [SettingsUtils daysToRetainHistory] is as follows; + (int) daysToRetainHistory { return (int)[[NSUserDefaults standardUserDefaults] objectForKey:@"CaseBaseDaysToRetainHistory"]; } I get the compiler warning Invalid receiver type 'int' because I call intValue on an int but unless I do this I can't seem to get the integer value out and always end up with the memory address i.e. 98765432 instead of 9 which ruins the UILabel display [retainHistory] and the UISlider [daysToRetainHistory] value. How do I avoid the compiler warning and still get my integer value in the label and the necessary float value for setting the UISlider value?

  • JavaScript regular expression literal persists between function calls

    - by Charles Anderson
    I have this piece of code: function func1(text) { var pattern = /([\s\S]*?)(\<\?(?:attrib |if |else-if |else|end-if|search |for |end-for)[\s\S]*?\?\>)/g; var result; while (result = pattern.exec(text)) { if (some condition) { throw new Error('failed'); } ... } } This works, unless the throw statement is executed. In that case, the next time I call the function, the exec() call starts where it left off, even though I am supplying it with a new value of 'text'. I can fix it by writing var pattern = new RegExp('.....'); instead, but I don't understand why the first version is failing. How is the regular expression persisting between function calls? (This is happening in the latest versions of Firefox and Chrome.) Edit Complete test case: <!DOCTYPE HTML> <html> <head> <meta http-equiv="Content-type" content="text/html;charset=UTF-8"> <title>Test Page</title> <style type='text/css'> body { font-family: sans-serif; } #log p { margin: 0; padding: 0; } </style> <script type='text/javascript'> function func1(text, count) { var pattern = /(one|two|three|four|five|six|seven|eight)/g; log("func1"); var result; while (result = pattern.exec(text)) { log("result[0] = " + result[0] + ", pattern.index = " + pattern.index); if (--count <= 0) { throw "Error"; } } } function go() { try { func1("one two three four five six seven eight", 3); } catch (e) { } try { func1("one two three four five six seven eight", 2); } catch (e) { } try { func1("one two three four five six seven eight", 99); } catch (e) { } try { func1("one two three four five six seven eight", 2); } catch (e) { } } function log(msg) { var log = document.getElementById('log'); var p = document.createElement('p'); p.innerHTML = msg; log.appendChild(p); } </script> </head> <body><div> <input type='button' id='btnGo' value='Go' onclick='go();'> <hr> <div id='log'></div> </div></body> </html> The regular expression continues with 'four' as of the second call on FF and Chrome, not on IE7 or Opera.

  • SQL join from multiple tables

    - by Kenny Anderson
    Hi all We've got a system (MS SQL 2008 R2-based) that has a number of "input" database and a one "output" database. I'd like to write a query that will read from the output DB, and JOIN it to data in one of the source DB. However, the source table may be one or more individual tables :( The name of the source DB is included in the output DB; ideally, I'd like to do something like the following (pseudo-SQL ahoy) SELECT output.UID, output.description, input.data from output.dbo.description LEFT JOIN (SELECT input.UID, input.data FROM [output.sourcedb].dbo.datatable ) AS input ON input.UID=output.UID Is there any way to do something like the above - "dynamically" specify the database and table to be joined on for each row in the query?

  • Linq Query ignore empty parameters

  • How can I break if gdb is attached, but continue if it is not?

    - by Michael Anderson
    I have some debugging code that if executed while running with GBD attached should break the execution of the application, but if GDB is not running it should continue. The code I'm working with looks something like this in structure: try { if( some_complex_expression ) { gdb_should_berak_here(); do_some_stuff(); throw MyException(); } } catch( const MyException & e ) { handle_exception_and_continue(); } What should gdb_should_break_here be?

  • How can I track down these Firefox warning messages?

    - by Charles Anderson
    Since I upgraded to jQuery 1.4.4 I've been getting several new warning messages when I run my unit tests in Firefox 3.6.13. Here's a typical one: Warning: Unexpected token in attribute selector: '!'. Source File: http://localhost/unitTests/devunitTests.html Line: 0 Or the even more useful: Warning: Selector expected. Source File: http://localhost/unitTests/ui/editors/iframe2.html?test=15 Line: 0 The web page renders nicely, and all my JavaScript code seems to be running okay too, so I'm reluctant to spend a potentially large amount of time chopping away at my code to track these messages down. However, can anyone suggest what's provoking the warnings?

  • d3 tree - parents having same children

    - by Larry Anderson
    I've been transitioning my code from JIT to D3, and working with the tree layout. I've replicated http://mbostock.github.com/d3/talk/20111018/tree.html with my tree data, but I wanted to do a little more. In my case I will need to create child nodes that merge back to form a parent at a lower level, which I realize is more of a directed graph structure, but would like the tree to accomodate (i.e. notice that common id's between child nodes should merge). So basically a tree that divides like normal on the way from parents to children, but then also has the ability to bring those children nodes together to be parents (sort of an incestual relationship or something :)). Asks something similar - How to layout a non-tree hierarchy with D3 It sounds like I might be able to use hierarchical edge bundling in conjunction with the tree hierarchy layout, but I haven't seen that done. I might be a little off with that though.

  • Android - Looping Activity to Repeat MediaPlayer

    - by Austin Anderson
    I'm trying to create a soundboard for longer audio files and can't figure out how to stop an audio file and start it again without closing the activity. Let's say each audio file is one minute long. If I play the first audio file for 20 seconds and start the next audio file, the first stops playing and the second starts playing. However, if I click the first audio file again, the second stops playing and the first does not. I need help. This is driving me insane. bAudio1 = (ImageButton) findViewById(R.id.bAudio1); bAudio2 = (ImageButton) findViewById(R.id.bAudio2); mpAudio1 = MediaPlayer.create(this, R.raw.audio1); mpAudio2 = MediaPlayer.create(this, R.raw.audio2); bAudio1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(mpAudio1.isPlaying()) { mpAudio1.stop(); } else { if(mpAudio2.isPlaying()) { mpAudio2.stop(); } mpAudio1.start(); } } }); bAudio2.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(mpAudio2.isPlaying()) { mpAudio2.stop(); } else { if(mpAudio1.isPlaying()) { mpAudio1.stop(); } mpAudio2.start(); } } }); Thanks.

  • Detecting Handlers of a jQuery "Live" Event

    - by Anderson De Andrade
    Using: $('#foo').data('events').click We are able to access an iterative object of click handlers added to the element '#foo' but only when they were added with .bind() Is there a way to get the handlers for an event added with .live()? Is there any other way to know if an element has a click handler assigned?

  • Push alerts to notification tray app in Java

    - by Rich Anderson
    Hi - how do I push server alerts to tray apps in java without using xmpp or other heavy protocols? Do you recommend a way to accomplish this? I was planning to write an app which uses URLConnection on a server equipped with Comet but I doubt if that would work as the client requires a JS to be invoked and URLConnection is not a browser.. What is the best way to push instead of using a proprietary client-server approach?

  • Thread resource sharing

    - by David
    I'm struggling with multi-threaded programming... I have an application that talks to an external device via a CAN to USB module. I've got the application talking on the CAN bus just fine, but there is a requirement for the application to transmit a "heartbeat" message every second. This sounds like a perfect time to use threads, so I created a thread that wakes up every second and sends the heartbeat. The problem I'm having is sharing the CAN bus interface. The heartbeat must only be sent when the bus is idle. How do I share the resource? Here is pseudo code showing what I have so far: TMainThread { Init: CanBusApi =new TCanBusApi; MutexMain =CreateMutex( "CanBusApiMutexName" ); HeartbeatThread =new THeartbeatThread( CanBusApi ); Execution: WaitForSingleObject( MutexMain ); CanBusApi->DoSomething(); ReleaseMutex( MutexMain ); } THeartbeatThread( CanBusApi ) { Init: MutexHeart =CreateMutex( "CanBusApiMutexName" ); Execution: Sleep( 1000 ); WaitForSingleObject( MutexHeart ); CanBusApi->DoHeartBeat(); ReleaseMutex( MutexHeart ); } The problem I'm seeing is that when DoHeartBeat is called, it causes the main thread to block while waiting for MutexMain as expected, but DoHeartBeat also stops. DoHeartBeat doesn't complete until after WaitForSingleObject(MutexMain) times out in failure. Does DoHeartBeat execute in the context of the MainThread or HeartBeatThread? It seems to be executing in MainThread. What am I doing wrong? Is there a better way? Thanks, David

  • Array of ArrayList Java

    - by David Bobo
    Hi, I am creating an PriorityQueue with multiple queues. I am using an Array to store the multiple ArrayLists that make up my different PriorityQueues. Here is what I have for my constructor so far: ArrayList<ProcessRecord> pq; ArrayList[] arrayQ; MultiList(){ arrayQ = new ArrayList[9]; pq = new ArrayList<ProcessRecord>(); } The problem comes when I am trying to get the size of the entire array, that is the sum of the sizes of each ArrayList in the array. public int getSize(){ int size = 0; for(int i = 1; i <=9; i++){ size = size + this.arrayQ[i].size(); } return size; } is not seeming to work. Am I declaring the Array of ArrayList correctly? I keep getting an error saying that this.arrayQ[i].size() is not a method. (the .size() being the problem) Thanks for any help! David

  • Visual Studio template not showing

    - by David
    Hi all I've followed this tutorial to try to add a template to Visual Studio: http://www.switchonthecode.com/tutorials/visual-studio-how-to-create-item-templates The template I have created is designed to add one predefined .aspx and one predefined .aspx.cs file to the project. The folder contains the following files: MoosePage.aspx MoosePage.aspx.cs MoosePage.vstemplate MoosePageItemTemplateIcon.ico The .vstemplate file looks like this: <VSTemplate Type="Item" Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005"> <TemplateData> <Name>MoosePage</Name> <Description>MoosePage Template</Description> <DefaultName>NewMoosePage</DefaultName> <ProjectType>CSharp</ProjectType> <Icon>MoosePageItemTemplateIcon.ico</Icon> </TemplateData> <TemplateContent> <ProjectItem TargetFileName="$fileinputname$.aspx" ReplaceParameters="true"> MoosePage.aspx </ProjectItem> <ProjectItem TargetFileName="$fileinputname$.aspx.cs" ReplaceParameters="true"> MoosePage.aspx.cs </ProjectItem> </TemplateContent> </VSTemplate> I have zipped the files up (.zip not .zipx) and placed the zip folder in My Documents\Visual Studio 2008\Templates\ItemTemplates\VisualWebDeveloper. I have restarted Visual Studio. When I go into my website project and choose Add New Item, I don't see my new template. Can anyone suggest what might have gone wrong? Thanks David

  • Need advice on OOP philosophy

    - by David Jenings
    I'm trying to get the wheels turning on a large project in C#. My previous experience is in Delphi, where by default every form was created at applicaton startup and form references where held in (gasp) global variables. So I'm trying to adapt my thinking to a 100% object oriented environment, and my head is spinning just a little. My app will have a large collection of classes Most of these classes will only really need one instance. So I was thinking: static classes. I'm not really sure why, but much of what I've read here says that if my class is going to hold a state, which I take to mean any property values at all, I should use a singleton structure instead. Okay. But there are people out there who for reasons that escape me, think that singletons are evil too. None of these classes is in danger of being used anywhere except in this program. So they could certainly work fine as regular objects (vs singletons or static classes) Then there's the issue of interaction between objects. I'm tempted to create a Global class full of public static properties referencing the single instances of many of these classes. I've also considered just making them properties (static or instance, not sure which) of the MainForm. Then I'd have each of my classes be aware of the MainForm as Owner. Then the various objects could refer to each other as Owner.Object1, Owner.Object2, etc. I fear I'm running out of electronic ink, or at least taxing the patience of anyone kind enough to have stuck with me this long. I hope I have clearly explained my state of utter confusion. I'm just looking for some advice on best practices in my situation. All input is welcome and appreciated. Thanks in advance, David Jennings

  • Is there a GUI that I can use to create XML documents based on my schema?

    - by David Conlisk
    Hi all, I want to create a simple graphical user interface to allow non-technical users to create an XML file without having to manually edit the XML source. Ideally I'd like a drag and drop interface, but failing that, anything really. The contents of the XML file are similar to an encoded flow chart of a binary tree, so maybe something like Visio, with a save as xml option? Here's a quick sample of the XML output that is required: <?xml version="1.0" encoding="utf-8"?> <steps> <step id="1" type="prompt"> <prompt> Welcome. </prompt> <next>1.1</next> </step> <step id="1.1" type="question"> <prompt> Do you have what you need? </prompt> <yes>1.2</yes> <no>1.1.1</no> </step> ... </steps> Are there any existing tools out there that you can recommend for this purpose? Ideally open-source or with a free personal license, but I'm interested in hearing about all options. Thanks, David

  • Checkstyle: cannot summarise issues per author ?

    - by David Michel
    Hi all, I'm trying to use checkstyle for a java project but I can't seem to get it working properly: While it apparently runs smoothly, the html report doesn't give any info per authors as it should, i.e. the authors table is empty. The thing is I don't know how checkstyle identify an author. Does it look at the java doc tag @author ? at the class level or at the method level ? The ant task I used is below: <taskdef resource="checkstyletask.properties" classpath="${libs.dir}/checkstyle-all-5.0.jar"/> <target name="checkstyle" description="Generates a report of code convention violations."> <mkdir dir="${checkstyle.dir}"/> <checkstyle config="${util.dir}/checkstyle/sun_checks.xml" failureProperty="checkstyle.failure" failOnViolation="false"> <formatter type="xml" tofile="${checkstyle.dir}/checkstyle_report.xml"/> <fileset dir="${src.dir}" includes="**/*.java"/> </checkstyle> <xslt in="${checkstyle.dir}/checkstyle_report.xml" out="${checkstyle.dir}/checkstyle_report.html" style="${util.dir}/checkstyle/checkstyle-author.xsl"/> </target> Many thanks for your help David

  • Run a .java file using ProcessBuilder

    - by David K
    I'm a novice programmer working in Eclipse, and I need to get multiple processes running (this is going to be a simulation of a multi-computer system). My initial hackup used multiple threads to multiple classes, but now I'm trying to replace the threads with processes. From my reading, I've gleaned that ProcessBuilder is the way to go. I have tried many many versions of the input you see below, but cannot for the life of me figure out how to properly use it. I am trying to run the .java files I previously created as classes (which I have modified). I eventually just made a dummy test.java to make sure my process is working properly - its only function is to print that it ran. My code for the two files are below. Am I using ProcessBuilder correctly? Is this the correct way to read the output of my subprocess? Any help would be much appreciated. David primary process package Control; import java.io.*; import java.lang.*; public class runSPARmatch { /** * @param args */ public static void main(String args[]) { try { ProcessBuilder broker = new ProcessBuilder("javac.exe","test.java","src\\Broker\\"); Process runBroker = broker.start(); Reader reader = new InputStreamReader(runBroker.getInputStream()); int ch; while((ch = reader.read())!= -1) System.out.println((char)ch); reader.close(); runBroker.waitFor(); System.out.println("Program complete"); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } subprocess package Broker; public class test { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub System.out.println("This works"); } }

  • How to run validator from javascript?

    - by David Shochet
    Here is a part of my code: <asp:ListBox ID="lbRD" runat="server" DataSourceID="RDSqlDataSource" onchange="JSFillDetail();" DataTextField="????????" DataValueField="ID" Width="188px" Height="200px"/> <asp:TextBox ID="txtDescription" runat="server" /> <asp:RequiredFieldValidator ID="txtDescriptionRequiredFieldValidator" runat="server" ErrorMessage="???????? ???????? ???????????? ??? ??????????" ControlToValidate="txtDescription" /> I have a listbox, a textbox and a required field validator on my page. When the user selects something from the listbox, the selected item appears in the textbox using a javascript function. When the page is submitted, the validator reports an error in case the textbox is empty. If after that the user selects something from the listbox, the error message is still displayed, even though the textbox is not empty anymore. How can I make the validator validate the textbox, or even better, to clear the error message from the javascript function that fills the textbox? Thanks, David

  • .NET: Problems creating email attachment from MemoryStream.

    - by David
    Hi all I'm using the following method to create an attachment from a MemoryStream: public void AddAttachment(Stream stream, string filename, string mimeType) { byte[] buffer = ((MemoryStream) stream).GetBuffer(); Attachment attachment = new Attachment(stream, filename, mimeType); _mail.Attachments.Add(attachment); } Note that the first line is not necessary isn't necessary for the attachment functionality, it's just useful to have the byte[] handy during debugging so that I can see how big it is. (It generally has around 80,000 elements.) The code runs fine and the email is sent. When Outlook receives the email, in the Inbox it displays the attachment symbol, but when you go into the email the attachment isn't there. Unfortunately I don't have access to the mail server to find out more about the email, e.g. what the attachment looks like, its size etc. Can anyone suggest what properties of the MemoryStream argument might tell me if it is in some way invalid for attachment? Or think of anything else I might try? Thank you. David
