• TreeViewItem - Use ControlTemplate and HierarchicalDataTemplate together

  - by CrownJ

  I'm using HierarchicalDataTemplate in my TreeView, and I wanted to also overwrite the default template for the TreeViewItem so that when an item is selected, it only highlights the text, not including the icon next to it. <TreeView.ItemTemplate> <HierarchicalDataTemplate ItemsSource="{Binding Children}"> <TreeViewItem Style="{StaticResource TreeViewItemStyle}" Header="{Binding DisplayText}" /> </HierarchicalDataTemplate> </TreeView.ItemTemplate> <TreeView.Resources> <Style x:Key="TreeViewItemFocusVisual"> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate>

also change parts of the control's behavior. When I do the above code, it won't select the treeviewitem at all.

• Confusing Java syntax...

  I'm trying to convert the following code (from Wikipedia) from Java to JavaScript: /* * 3 June 2003, [[:en:User:Cyp]]: * Maze, generated by my algorithm * 24 October 2006, [[:en:User:quin]]: * Source edited for clarity * 25 January 2009, [[:en:User:DebateG]]: * Source edited again for clarity and reusability * 1 June 2009, [[:en:User:Nandhp]]: * Source edited to produce SVG file when run from the command-line * * This program was originally written by [[:en:User:Cyp]], who * attached it to the image description page for an image generated by * it on en.wikipedia.

I'm sure there's a good reason for this. Problem is, I just don't get it. Thanks!

• Remote EJB lookup issue with WebSphere 6.1

  - by marc dauncey

  I've seen this question asked before, but I've tried various solutions proposed, to no avail. Essentially, I have two EJB enterprise applications, that need to communicate with one another. The first is a web application, the second is a search server - they are located on different development servers, not in the same node, cell, or JVM, although they are on the same physical box. I'm doing the JNDI lookup via IIOP, and the URL I am using is as follows: iiop://searchserver:2819 In my hosts file, I've set searchserver to 127.0.0.1. The ports for my search server are bound to this hostname too. However, when the web app (that uses Spring btw) attempts to lookup the search EJB, it fails with the following error. This is driving me nuts, surely this kind of comms between the servers should be fairly simple to get working. I've checked the ports and they are correct. I note that the exception says the initial context is H00723Node03Cell/nodes/H00723Node03/servers/server1, name: ejb/com/hmv/dataaccess/ejb/hmvsearch/HMVSearchHome. This is the web apps server NOT the search server. Is this correct? How can I get Spring to use the right context?

• What does a Software Developer actually do?

  - by chobo2

  Hi I am graduating from my Computer Science degree in a few weeks from now!! I started to look for my first job. For the last couple years I gotten really into web programming(Asp.net). My first choice would be to get a junior asp.net MVC developer but I don't any companies in my area use MVC yet or if they do they are not hiring. So my second choice would be a junior asp.net Webforms developer. My other choices after that would be forms applications, mobile applications using .Net and C#. As you can see I am looking for something with .Net. I spent the last couple years doing .Net projects for school, on my free time and love the Language and it would pain me right now to switch to something like php. So now I found a posting in my area for an Entry Software Developer. I like the fact that they are using .net and that it is entry job(I never worked in this industry and never had more then like a tutoring job so I want to for like intermediate jobs). Posting Are you looking for an exciting challenge within a dynamic, people-oriented culture where you can launch your technical career? Company Name Inc. is a technology consulting company, located in Canada, that designs, develops, and delivers real-time interactive applications accessed via the Internet as well as back-end tools to support these applications. Company Name provides a combination of out-of-the-box and customized solutions to an expanding list of partners and customers. POSITION SUMMARY As a member of our team, the successful candidate will be responsible for helping us increase the quality and stability of our software systems by working jointly and directly with both the Software Development teams and the QA Team. The primary mission of this role will be to substantially enhance our test automation suite. The incumbent will design and program automated tests (unit, integration, system, stress and load) in Visual Studio using C# and will develop sound processes that help us identify and resolve defects as early as possible. The successful incumbent will help us improve and enhance system functionality, reliability, performance and scalability. This role is specifically designed for an eager, bright, new graduate who is looking for a stepping stone into a software engineering role. We promote from within and invite new graduates to apply for this important position - which may lead to new opportunities. We also offer a generous professional development plan to help you on your way. You will be a key part of a team of experts that is responsible for improving the quality of our software by: • Designing, writing, and executing test plans and programmatic tests in Visual Studio using C# and NUnit for functional testing of our code, new features, regression, and performance test procedures. • Working with the engineers to design and build the stress and load testing framework which emulates tens and even hundreds of thousands of concurrent users via a distributed network interfacing with our Load Testing Lab. • Interfacing with both the Development Team and the QA Team to ensure risks are identified and managed. • Mentoring and leading the QA Team in programmatic test automation technologies and tools. MUST HAVE SKILLS / QUALIFICATIONS: • Diploma or higher Degree in Computer Science, or equivalent formal training. • Fundamental C# programming skills. • Knowledge of Internet technologies and Microsoft Windows platforms. • Knowledge of PC hardware. • Excellent communication skills (both oral and written). • Self-starter who takes initiative, requires minimal supervision, can handle multiple simultaneous tasks. • Detail-oriented, able to concentrate, and work quickly. • Proven diagnostic, analytical, and problem solving skills. NICE TO HAVE SKILLS: • Exposure to Visual Studio Team System or Visual Studio Test Edition. • Exposure in C# using NUnit. • Exposure to NUnit, HTTPUnit, and other automation tool suites. • Exposure to Performance/Stress/Load Testing. • Good understanding of relational databases (MS SQL Server). • Familiar with video and online multi-player games. As part of our team you will have the opportunity to work with a supportive team of experts, drive your own success, and ride the wave as we continually expand our team of experts. If you are interested in this opportunity, please send your resume to [email protected] with “Entry Level Software Developer” in the subject line. So that is the posting. To me it sounds like it is QA job. I don't have anything against QA jobs but alot of them seems to be your just clicking buttons and running scripts. Is this what a typical software developer does? Like I am so on the fence to apply for this job. On one side I am not sure how much programming I would be doing. Like I want to be at least half the time programming otherwise my skills will never improve since I will never be programming in teams and stuff. At the same time I have no experience in the industry so on the other side I am thinking just go for it and then maybe a year later try to get a full programming job(provided that I got the job). Yet if I am not programming in that job then that experience will not help me for the next job I find as I will be back a square one.

• Advice on my jQuery Ajax Function

  - by NessDan

  So on my site, a user can post a comment on 2 things: a user's profile and an app. The code works fine in PHP but we decided to add Ajax to make it more stylish. The comment just fades into the page and works fine. I decided I wanted to make a function so that I wouldn't have to manage 2 (or more) blocks of codes in different files. Right now, the code is as follows for the two pages (not in a separate .js file, they're written inside the head tags for the pages.): // App page $("input#comment_submit").click(function() { var comment = $("#comment_box").val(); $.ajax({ type: "POST", url: "app.php?id=<?php echo $id; ?>", data: {comment: comment}, success: function() { $("input#comment_submit").attr("disabled", "disabled").val("Comment Submitted!"); $("textarea#comment_box").attr("disabled", "disabled") $("#comments").prepend("<div class=\"comment new\"></div>"); $(".new").prepend("<a href=\"profile.php?username=<?php echo $_SESSION['username']; ?>\" class=\"commentname\"><?php echo $_SESSION['username']; ?></a><p class=\"commentdate\"><?php echo date("M. d, Y", time()) ?> - <?php echo date("g:i A", time()); ?></p><p class=\"commentpost\">" + comment + "</p>").hide().fadeIn(1000); } }); return false; }); And next up, // Profile page $("input#comment_submit").click(function() { var comment = $("#comment_box").val(); $.ajax({ type: "POST", url: "profile.php?username=<?php echo $user; ?>", data: {comment: comment}, success: function() { $("input#comment_submit").attr("disabled", "disabled").val("Comment Submitted!"); $("textarea#comment_box").attr("disabled", "disabled") $("#comments").prepend("<div class=\"comment new\"></div>"); $(".new").prepend("<a href=\"profile.php?username=<?php echo $_SESSION['username']; ?>\" class=\"commentname\"><?php echo $_SESSION['username']; ?></a><p class=\"commentdate\"><?php echo date("M. d, Y", time()) ?> - <?php echo date("g:i A", time()); ?></p><p class=\"commentpost\">" + comment + "</p>").hide().fadeIn(1000); } }); return false; }); Now, on each page the box names will always be the same (comment_box and comment_submit) so what do you guys think of this function (Note, the postComment is in the head tag on the page.): // On the page, (profile.php) $(function() { $("input#comment_submit").click(function() { postComment("profile", "<?php echo $user ?>", "<?php echo $_SESSION['username']; ?>", "<?php echo date("M. d, Y", time()) ?>", "<?php echo date("g:i A", time()); ?>"); }); }); Which leads to this function (which is stored in a separate file called functions.js): function postComment(page, argvalue, username, date, time) { if (page == "app") { var arg = "id"; } if (page == "profile") { var arg = "username"; } var comment = $("#comment_box").val(); $.ajax({ type: "POST", url: page + ".php?" + arg + "=" + argvalue, data: {comment: comment}, success: function() { $("textarea#comment_box").attr("disabled", "disabled") $("input#comment_submit").attr("disabled", "disabled").val("Comment Submitted!"); $("#comments").prepend("<div class=\"comment new\"></div>"); $(".new").prepend("<a href=\"" + page + ".php?" + arg + "=" + username + "\" class=\"commentname\">" + username + "</a><p class=\"commentdate\">" + date + " - " + time + "</p><p class=\"commentpost\">" + nl2br(comment) + "</p>").hide().fadeIn(1000); } }); return false; } That's what I came up with! So, some problems: When I hit the button the page refreshes. What fixed this was taking the return false from the function and putting it into the button click. Any way to keep it in the function and have the same effect? But my real question is this: Can any coders out there that are familiar to jQuery tell me techniques, coding practices, or ways to write my code more efficiently/elegantly? I've done a lot of work in PHP but I know that echoing the date may not be the most efficient way to get the date and time. So any tips that can really help me streamline this function and also make me better with writing jQuery are very welcome!

• Silverlight Chat WrapPanel Crash / Bug

  - by Matt

  I've been given the task to create a simple Silverlight chat box for two people. My control must adhere to the following requirements Scrollable Text must wrap if it's too long When a new item / message is added it must scroll that item into view Now I've successfully made a usercontrol to meet these requirements, but I've run into a possible bug / crash that I can't for the life of me fix. I'm looking for either a fix to the bug, or a different approach to creating a scrollable chat control. Here's the code I've been using. We'll start with my XAML for the chat window <ListBox x:Name="lbChatHistory" Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" ScrollViewer.VerticalScrollBarVisibility="Visible" ScrollViewer.HorizontalScrollBarVisibility="Disabled" > <ListBox.ItemTemplate> <DataTemplate> <Grid Background="Beige"> <Grid.ColumnDefinitions> <ColumnDefinition Width="70"></ColumnDefinition> <ColumnDefinition Width="Auto"></ColumnDefinition> </Grid.ColumnDefinitions> <TextBlock x:Name="lblPlayer" Foreground="{Binding ForeColor}" Text="{Binding Player}" Grid.Column="0"></TextBlock> <ContentPresenter Grid.Column="1" Width="200" Content="{Binding Message}" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> The idea is to add a new Item to the listbox. The Item (as layed out in the XAML) is a simple 2 column grid. One column for the username, and one column for the message. Now the "items" that I add to the ListBox is a custom class. It has three properties (Player, ForeColor, and Message) that I using binding on within my XAML Player is a string of the current user to display. ForeColor is just a foreground color preference. It helps distinguish the difference between messages. Message is a WrapPanel. I programmatically break the supplied string on the white space for each word. Then for each word, I add a new TextBlock element to the WrapPanel Here is the custom class. public class ChatMessage :DependencyObject, INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public static DependencyProperty PlayerProperty = DependencyProperty.Register( "Player", typeof( string ), typeof( ChatMessage ), new PropertyMetadata( new PropertyChangedCallback( OnPlayerPropertyChanged ) ) ); public static DependencyProperty MessageProperty = DependencyProperty.Register( "Message", typeof( WrapPanel ), typeof( ChatMessage ), new PropertyMetadata( new PropertyChangedCallback( OnMessagePropertyChanged ) ) ); public static DependencyProperty ForeColorProperty = DependencyProperty.Register( "ForeColor", typeof( SolidColorBrush ), typeof( ChatMessage ), new PropertyMetadata( new PropertyChangedCallback( OnForeColorPropertyChanged ) ) ); private static void OnForeColorPropertyChanged( DependencyObject d, DependencyPropertyChangedEventArgs e ) { ChatMessage c = d as ChatMessage; c.ForeColor = ( SolidColorBrush ) e.NewValue; } public ChatMessage() { Message = new WrapPanel(); ForeColor = new SolidColorBrush( Colors.White ); } private static void OnMessagePropertyChanged( DependencyObject d, DependencyPropertyChangedEventArgs e ) { ChatMessage c = d as ChatMessage; c.Message = ( WrapPanel ) e.NewValue; } private static void OnPlayerPropertyChanged( DependencyObject d, DependencyPropertyChangedEventArgs e ) { ChatMessage c = d as ChatMessage; c.Player = e.NewValue.ToString(); } public SolidColorBrush ForeColor { get { return ( SolidColorBrush ) GetValue( ForeColorProperty ); } set { SetValue( ForeColorProperty, value ); if(PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs( "ForeColor" )); } } public string Player { get { return ( string ) GetValue( PlayerProperty ); } set { SetValue( PlayerProperty, value ); if ( PropertyChanged != null ) PropertyChanged( this, new PropertyChangedEventArgs( "Player" ) ); } } public WrapPanel Message { get { return ( WrapPanel ) GetValue( MessageProperty ); } set { SetValue( MessageProperty, value ); if ( PropertyChanged != null ) PropertyChanged( this, new PropertyChangedEventArgs( "Message" ) ); } } } Lastly I add my items to the ListBox. Here's the simple method. It takes the above ChatMessage class as a parameter public void AddChatItem( ChatMessage msg ) { lbChatHistory.Items.Add( msg ); lbChatHistory.ScrollIntoView( msg ); } Now I've tested this and it all works. The problem I'm getting is when I use the scroll bar. You can scroll down using the side scroll bar or arrow keys, but when you scroll up Silverlight crashes. FireBug returns a ManagedRuntimeError #4004 with a XamlParseException. I'm soo close to having this control work, I can taste it! Any thoughts on what I should do or change? Is there a better approach than the one I've taken? Thanks in advance. UPDATE I've found an alternative solution using a ScrollViewer and an ItemsControl instead of a ListBox control. For the most part it's stable.

• Windows 2008 RenderFarm Service: CreateProcessAsUser "Session 0 Isolation" and OpenGL

  - by holtavolt

  Hello, I have a legacy Windows server service and (spawned) application that works fine in XP-64 and W2K3, but fails on W2K8. I believe it is because of the new "Session 0 isolation " feature. (Note: As a StackOverflow newbie I'm being limited to one link in this post, so you'll need to scroll to bottom to lookup the links for '' items)* Consequently, I'm looking for code samples/security settings mojo that let you create a new process from a windows service for Windows 2008 Server such that I can restore (and possibly surpass) the previous behavior. I need a solution that: Creates the new process in a non-zero session to get around session-0 isolation restrictions (no access to graphics hardware from session 0) - the official MS line on this is: Because Session 0 is no longer a user session, services that are running in Session 0 do not have access to the video driver. This means that any attempt that a service makes to render graphics fails. Querying the display resolution and color depth in Session 0 reports the correct results for the system up to a maximum of 1920x1200 at 32 bits per pixel. The new process gets a windows station/desktop (e.g. winsta0/default) that can be used to create windows DCs. I've found a solution (that launches OK in an interactive session) for this here: *(Starting an Interactive Client Process in C++ - 2) The windows DC, when used as the basis for an *(OpenGL DescribePixelFormat enumeration - 3), is able to find and use the hardware-accelerated format (on a system appropriately equipped with OpenGL hardware.) Note that our current solution works OK on XP-64 and W2K3, except if a terminal services session is running (VNC works fine.) A solution that also allowed the process to work (i.e. run with OpenGL hardware acceleration even when a terminal services session is open) would be fanastic, although not required. I'm stuck at item #1 currently, and although there are some similar postings that discuss this (like *(this -4), and *(this - 5) - they are not suitable solutions, as there is no guarantee of a user session logged in already to "take" a session id from, nor am I running from a LocalSystem account (I'm running from a domain account for the service, for which I can adjust the privileges of, within reason, although I'd prefer to not have to escalate priorities to include SeTcbPrivileges.) For instance - here's a stub that I think should work, but always returns an error 1314 on the SetTokenInformation call (even though the AdjustTokenPrivileges returned no errors) I've used some alternate strategies involving "LogonUser" as well (instead of opening the existing process token), but I can't seem to swap out the session id. I'm also dubious about using the WTSActiveConsoleSessionId in all cases (for instance, if no interactive user is logged in) - although a quick test of the service running with no sessions logged in seemed to return a reasonable session value (1). I’ve removed error handling for ease of reading (still a bit messy - apologies) //Also tried using LogonUser(..) here OpenProcessToken(GetCurrentProcess(), TOKEN_QUERY | TOKEN_ADJUST_PRIVILEGES | TOKEN_ADJUST_SESSIONID | TOKEN_ADJUST_DEFAULT | TOKEN_ASSIGN_PRIMARY | TOKEN_DUPLICATE, &hToken) GetTokenInformation( hToken, TokenSessionId, &logonSessionId, sizeof(DWORD), &dwTokenLength ) DWORD consoleSessionId = WTSGetActiveConsoleSessionId(); /* Can't use this - requires very elevated privileges (LOCAL only, SeTcbPrivileges as well) if( !WTSQueryUserToken(consoleSessionId, &hToken)) ... */ DuplicateTokenEx(hToken, (TOKEN_QUERY | TOKEN_ADJUST_PRIVILEGES | TOKEN_ADJUST_SESSIONID | TOKEN_ADJUST_DEFAULT | TOKEN_ASSIGN_PRIMARY | TOKEN_DUPLICATE), NULL, SecurityIdentification, TokenPrimary, &hDupToken)) // Look up the LUID for the TCB Name privilege. LookupPrivilegeValue(NULL, SE_TCB_NAME, &tp.Privileges[0].Luid)) // Enable the TCB Name privilege in the token. tp.PrivilegeCount = 1; tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; if (!AdjustTokenPrivileges(hDupToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), NULL, 0)) { DisplayError("AdjustTokenPrivileges"); ... } if (GetLastError() == ERROR_NOT_ALL_ASSIGNED) { DEBUG( "Token does not have the necessary privilege.\n"); } else { DEBUG( "No error reported from AdjustTokenPrivileges!\n"); } // Never errors here DEBUG(LM_INFO, "Attempting setting of sessionId to: %d\n", consoleSessionId ); if (!SetTokenInformation(hDupToken, TokenSessionId, &consoleSessionId, sizeof(DWORD))) *** ALWAYS FAILS WITH 1314 HERE *** All the debug output looks fine up until the SetTokenInformation call - I see session 0 is my current process session, and in my case, it's trying to set session 1 (the result of the WTSGetActiveConsoleSessionId). (Note that I'm logged into the W2K8 box via VNC, not RDC) So - a the questions: Is this approach valid, or are all service-initiated processes restricted to session 0 intentionally? Is there a better approach (short of "Launch on logon" and auto-logon for the servers?) Is there something wrong with this code, or a different way to create a process token where I can swap out the session id to indicate I want to spawn the process in a new session? I did try using LogonUser instead of OpenProcessToken, but that didn't work either. (I don't care if all spawned processes share the same non-zero session or not at this point.) Any help much appreciated - thanks!

• JQuery Pure Template

  - by cem

  I cant figure out whats wrong. Its working when i tried to refresh only topics but it doesnt works when tried to refresh topics and page-links. ie. topics table's refreshing, and 'pagelinks' disappearing, i thought pure cannot reach - read second template node. By the way, i tested their code, first message box show up all of nodes - includes 'pagelinks' node, but second one - in function only show up topic rows. Its look like a bug. Anyone knows how can i solve this? ps. I'm using latest version of pure. Thanks. Test Code - pure.js line: 189 function dataselectfn(sel) { // ... m = sel.split('.'); alert(m.toSource()); return function (ctxt) { var data = ctxt.context; if (!data) { return ''; } alert('in function: ' + m.toSource()); // ...

• Silverlight 2.0 - Can't get the text wrapping behaviour that I want

  - by Anthony

  I am having trouble getting Silverlight 2.0 to lay out text exactly how I want. I want text with line breaks and embedded links, with wrapping, like HTML text in a web page. Here's the closest that I have come: <UserControl x:Class="FlowPanelTest.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="clr-namespace:Microsoft.Windows.Controls;assembly=Microsoft.Windows.Controls" Width="250" Height="300"> <Border BorderBrush="Black" BorderThickness="2" > <Controls:WrapPanel> <TextBlock x:Name="tb1" TextWrapping="Wrap">Short text. </TextBlock> <TextBlock x:Name="tb2" TextWrapping="Wrap">A bit of text. </TextBlock> <TextBlock x:Name="tb3" TextWrapping="Wrap">About half of a line of text.</TextBlock> <TextBlock x:Name="tb4" TextWrapping="Wrap">More than half a line of longer text.</TextBlock> <TextBlock x:Name="tb5" TextWrapping="Wrap">More than one line of text, so it will wrap onto the following line.</TextBlock> </Controls:WrapPanel> </Border> </UserControl> But the issue is that although the text blocks tb1 and tb2 will go onto the same line because there is room enough for them completely, tb3 onwards will not start on the same line as the previous block, even though it will wrap onto following lines. I want each text block to start where the previous one ends, on the same line. I want to put click event handlers on some of the text. I also want paragraph breaks. Essentially I'm trying to work around the lack of FlowDocument and Hyperlink controls in Silverlight 2.0's subset of XAML. To answer the questions posed in the answers: Why not use runs for the non-clickable text? If I just use individual TextBlocks only on the clickable text, then those bits of text will still suffer from the wrapping problem illustrated above. And the TextBlock just before the link, and the TextBlock just after. Essentially all of it. It doesn't look like I have many opportunities for putting multiple runs in the same TextBlock. Dividing the links from the other text with RegExs and loops is not the issue at all, the issue is display layout. Why not put each word in an individual TextBlock in a WrapPanel Aside from being an ugly hack, this does not play at all well with linebreaks - the layout is incorrect. It would also make the underline style of linked text into a broken line. Here's an example with each word in its own TextBlock. Try running it, note that the linebreak isn't shown in the right place at all. <UserControl x:Class="SilverlightApplication2.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="clr-namespace:Microsoft.Windows.Controls;assembly=Microsoft.Windows.Controls" Width="300" Height="300"> <Controls:WrapPanel> <TextBlock TextWrapping="Wrap">Short1 </TextBlock> <TextBlock TextWrapping="Wrap">Longer1 </TextBlock> <TextBlock TextWrapping="Wrap">Longerest1 </TextBlock> <TextBlock TextWrapping="Wrap"> <Run>Break</Run> <LineBreak></LineBreak> </TextBlock> <TextBlock TextWrapping="Wrap">Short2</TextBlock> <TextBlock TextWrapping="Wrap">Longer2</TextBlock> <TextBlock TextWrapping="Wrap">Longerest2</TextBlock> <TextBlock TextWrapping="Wrap">Short3</TextBlock> <TextBlock TextWrapping="Wrap">Longer3</TextBlock> <TextBlock TextWrapping="Wrap">Longerest3</TextBlock> </Controls:WrapPanel> </UserControl> What about The LinkLabelControl as here and here. It has the same problems as the approach above, since it's much the same. Try running the sample, and make the link text longer and longer until it wraps. Note that the link starts on a new line, which it shouldn't. Make the link text even longer, so that the link text is longer than a line. Note that it doesn't wrap at all, it cuts off. This control doesn't handle line breaks and paragraph breaks either. Why not put the text all in runs, detect clicks on the containing TextBlock and work out which run was clicked Runs do not have mouse events, but the containing TextBlock does. I can't find a way to check if the run is under the mouse (IsMouseOver is not present in SilverLight) or to find the bounding geometry of the run (no clip property). There is VisualTreeHelper.FindElementsInHostCoordinates() The code below uses VisualTreeHelper.FindElementsInHostCoordinates to get the controls under the click. The output lists the TextBlock but not the Run, since a Run is not a UiElement. private void theText_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e) { // get the elements under the click UIElement uiElementSender = sender as UIElement; Point clickPos = e.GetPosition(uiElementSender); var UiElementsUnderClick = VisualTreeHelper.FindElementsInHostCoordinates(clickPos, uiElementSender); // show the controls string outputText = ""; foreach (var uiElement in UiElementsUnderClick) { outputText += uiElement.GetType().ToString() + "\n"; } this.outText.Text = outputText; } Use an empty text block with a margin to space following content onto a following line I'm still thinking about this one. How do you calculate the right width for a line-breaking block to force following content onto the following line? Too short and the following content will still be on the same line, at the right. Too long and the "linebreak" will be on the following line, with content after it. You would have to resize the breaks when the control is resized. Some of the code for this is: TextBlock lineBreak = new TextBlock(); lineBreak.TextWrapping = TextWrapping.Wrap; lineBreak.Text = " "; // need adaptive width lineBreak.Margin = new Thickness(0, 0, 200, 0);

• Does RVM "failover" to another ruby instance on error?

  - by JohnMetta

  Have a strange problem in that I have a Rake task that seems to be using multiple versions of Ruby. When one fails, it seems to try another one. Details MacBook running 10.6.5 rvm 1.1.0 Rubies: 1.8.7-p302, ree-1.8.7-2010.02, ruby-1.9.2-p0 Rake 0.8.7 Gem 1.3.7 Veewee (provisioning Virtual Machines using Opcode.com, Vagrant and Chef) I'm not entirely sure the specific details of the error matter, but since it might be an issue with Veewee itself. So, what I'm trying to do is build a new box base on a veewee definition. The command fails with an error about a missing method- but what's interesting is how it fails. Errors I managed to figure out that if I only have one Ruby installed with RVM, it just fails. If I have more than one Ruby install, it fails at the same place, but execution seems to continue in another interpreter. Here are two different clipped console outputs. I've clipped them for size. The full outputs of each error are available as a gist. One Ruby version installed Here is the command run when I only have a single version of Ruby (1.8.7) available in RVM boudica:veewee john$ rvm rake build['mettabox'] --trace rvm 1.1.0 by Wayne E.

Again, I don't know how important the details of the specific errors are- what's interesting to me is that there are three separate errors- each with it's own stacktrace- and each in a different Ruby interpreter.

Discussion Does anyone have any idea what's going on here? Has anyone seen this "failover"-like behavior before? It seems strange to me that the first exception would not halt execution as it did with one interpreter, but I wonder if there are things happening when RVM is installed that we Ruby developers are not considering.

• Why won't "!important" override ":first-line"?

  - by bazzlevi

  I am trying to do the tutorial in Chapter 6 of the 2nd edition of "CSS: The Missing Manual", and I've run into an issue I'm trying to understand. I have one style that looks like this: #main p:first-line { color: #999999; font-weight: bold; } Later I have another style that looks like this: #main p.byline { color: #00994D !important; font-size: 1.6em; margin: 5px 0 25px 50px; } I am confused because the second one won't override the color choice in the first one despite the fact that the second one has "!important" in it. I put both classes into an online specificity calculator, and the second one comes out being more specific, so I'm doubly confused. By the way, the inclusion of "!important" is the work-around suggested in the errata for the book. Odd that it still doesn't work!

• XHTML / CSS help?

  - by Chris Leah

  Basically on GunChester my project I have an few pixel wide gap between #login_top (top image holder) and the 3 CSS col's below, #login_left, #login_centre and #login_right so that my first question why? and how can I fix this, this is in FF, Chrome and IE. Secondly the BG image seems to be overlaying twice as in its stretched at the top then the full picture does display as it should. I did have it working but when trying to fix the pixel gap I must of messed something up but no idea what, so it is now going pear shape, lease help with both these situations :)?

• Google Chrome: JavaScript associative arrays, evaluated out of sequence

  - by Jerry

  Ok, so on a web page, I've got a JavaScript object which I'm using as an associative array. This exists statically in a script block when the page loads: var salesWeeks = { "200911" : ["11 / 2009", "Fiscal 2009"], "200910" : ["10 / 2009", "Fiscal 2009"], "200909" : ["09 / 2009", "Fiscal 2009"], "200908" : ["08 / 2009", "Fiscal 2009"], "200907" : ["07 / 2009", "Fiscal 2009"], "200906" : ["06 / 2009", "Fiscal 2009"], "200905" : ["05 / 2009", "Fiscal 2009"], "200904" : ["04 / 2009", "Fiscal 2009"], "200903" : ["03 / 2009", "Fiscal 2009"], "200902" : ["02 / 2009", "Fiscal 2009"], "200901" : ["01 / 2009", "Fiscal 2009"], "200852" : ["52 / 2008", "Fiscal 2009"], "200851" : ["51 / 2008", "Fiscal 2009"] }; The order of the key/value pairs is intentional, as I'm turning the object into an HTML select box such as this: <select id="ddl_sw" name="ddl_sw"> <option value="">== SELECT WEEK ==</option> <option value="200911">11 / 2009 (Fiscal 2009)</option> <option value="200910">10 / 2009 (Fiscal 2009)</option> <option value="200909">09 / 2009 (Fiscal 2009)</option> <option value="200908">08 / 2009 (Fiscal 2009)</option> <option value="200907">07 / 2009 (Fiscal 2009)</option> <option value="200906">06 / 2009 (Fiscal 2009)</option> <option value="200905">05 / 2009 (Fiscal 2009)</option> <option value="200904">04 / 2009 (Fiscal 2009)</option> <option value="200903">03 / 2009 (Fiscal 2009)</option> <option value="200902">02 / 2009 (Fiscal 2009)</option> <option value="200901">01 / 2009 (Fiscal 2009)</option> <option value="200852">52 / 2008 (Fiscal 2009)</option> <option value="200851">51 / 2008 (Fiscal 2009)</option> </select> ...with code that looks like this (snipped from a function): var arr = []; arr.push( "<select id=\"ddl_sw\" name=\"ddl_sw\">" + "<option value=\"\">== SELECT WEEK ==</option>" ); for(var key in salesWeeks) { arr.push( "<option value=\"" + key + "\">" + salesWeeks[key][0] + " (" + salesWeeks[key][1] + ")" + "<\/option>" ); } arr.push("<\/select>"); return arr.join(""); This all works fine in IE, FireFox and Opera. However in Chrome, the order comes out all weird: <select id="ddl_sw" name="ddl_sw"> <option value="">== SELECT WEEK ==</option> <option value="200852">52 / 2008 (Fiscal 2009)</option> <option value="200908">08 / 2009 (Fiscal 2009)</option> <option value="200906">06 / 2009 (Fiscal 2009)</option> <option value="200902">02 / 2009 (Fiscal 2009)</option> <option value="200907">07 / 2009 (Fiscal 2009)</option> <option value="200904">04 / 2009 (Fiscal 2009)</option> <option value="200909">09 / 2009 (Fiscal 2009)</option> <option value="200903">03 / 2009 (Fiscal 2009)</option> <option value="200905">05 / 2009 (Fiscal 2009)</option> <option value="200901">01 / 2009 (Fiscal 2009)</option> <option value="200910">10 / 2009 (Fiscal 2009)</option> <option value="200911">11 / 2009 (Fiscal 2009)</option> <option value="200851">51 / 2008 (Fiscal 2009)</option> </select> NOTE: This order, though weird, does not change on subsequent refreshes. It's always in this order. So, what is Chrome doing? Some optimization in how it processes the loop? In the first place, am I wrong to rely on the order that the key/value pairs are declared in any associative array? I never questioned it before, I just assumed the order would hold because this technique has always worked for me in the other browsers. But I suppose I've never seen it stated anywhere that the order is guaranteed. Maybe it's not? Any insight would be awesome. Thanks.

• Hung JVM consuming 100% CPU

  - by Bogdan

  We have a JAVA server running on Sun JRE 6u20 on Linux 32-bit (CentOS). We use the Server Hotspot with CMS collector with the following options (I've only provided the relevant ones): -Xmx896m -Xss128k -XX:NewSize=384M -XX:MaxPermSize=96m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC Sometimes, after running for a while, the JVM seems to slip into a hung state, whereby even though we don't make any requests to the application, the CPU continues to spin at 100% (we have 8 logical CPUs, so it looks like only one CPU does the spinning). In this state the JVM doesn't respond to SIGHUP signals (kill -3) and we can't connect to it normally with jstack. We CAN connect with "jstack -F", but the output is dodgy (we can see lots of NullPointerExceptions from JStack apparently because it wasn't able to 'walk' some stacks). So the "jstack -F" output seems to be useless. We have run a stack dump from "gdb" though, and we were able to match the thread id that spins the CPU (we found that using "top" with a per-thread view - "H" option) with a thread stack that appears in the gdb result and this is how it looks like: Thread 443 (Thread 0x7e5b90 (LWP 26310)): #0 0x0115ebd3 in CompactibleFreeListSpace::block_size(HeapWord const*) const () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #1 0x01160ff9 in CompactibleFreeListSpace::prepare_for_compaction(CompactPoint*) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #2 0x0123456c in Generation::prepare_for_compaction(CompactPoint*) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #3 0x01229b2c in GenCollectedHeap::prepare_for_compaction() () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #4 0x0122a7fc in GenMarkSweep::invoke_at_safepoint(int, ReferenceProcessor*, bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #5 0x01186024 in CMSCollector::do_compaction_work(bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #6 0x011859ee in CMSCollector::acquire_control_and_collect(bool, bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #7 0x01185705 in ConcurrentMarkSweepGeneration::collect(bool, bool, unsigned int, bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #8 0x01227f53 in GenCollectedHeap::do_collection(bool, bool, unsigned int, bool, int) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #9 0x0115c7b5 in GenCollectorPolicy::satisfy_failed_allocation(unsigned int, bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #10 0x0122859c in GenCollectedHeap::satisfy_failed_allocation(unsigned int, bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #11 0x0158a8ce in VM_GenCollectForAllocation::doit() () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #12 0x015987e6 in VM_Operation::evaluate() () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #13 0x01597c93 in VMThread::evaluate_operation(VM_Operation*) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #14 0x01597f0f in VMThread::loop() () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #15 0x015979f0 in VMThread::run() () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #16 0x0145c24e in java_start(Thread*) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #17 0x00ccd46b in start_thread () from /lib/libpthread.so.0 #18 0x00bc2dbe in clone () from /lib/libc.so.6 It seems that a JVM thread is spinning while doing some CMS related work. We have checked the memory usage on the box, there seems to be enough memory available and the system is not swapping. Has anyone come across such a situation? Does it look like a JVM bug? UPDATE I've obtained some more information about this problem (it happened again on a server that has been running for more than 7 days). When the JVM entered the "hung" state it stayed like that for 2 hours until the server was manually restarted. We have obtained a core dump of the process and the gc log. We tried to get a heap dump as well, but "jmap" failed. We tried to use jmap -F but then only a 4Mb file was written before the program aborted with an exception (something about the a memory location not being accessible). So far I think the most interesting information comes from the gc log. It seems that the GC logging stopped as well (possibly at the time when the VM thread went into the long loop): 657501.199: [Full GC (System) 657501.199: [CMS: 400352K->313412K(524288K), 2.4024120 secs] 660634K->313412K(878208K), [CMS Perm : 29455K->29320K(68568K)], 2.4026470 secs] [Times: user=2.39 sys=0.01, real=2.40 secs] 657513.941: [GC 657513.941: [ParNew: 314624K->13999K(353920K), 0.0228180 secs] 628036K->327412K(878208K), 0.0230510 secs] [Times: user=0.08 sys=0.00, real=0.02 secs] 657523.772: [GC 657523.772: [ParNew: 328623K->17110K(353920K), 0.0244910 secs] 642036K->330523K(878208K), 0.0247140 secs] [Times: user=0.08 sys=0.00, real=0.02 secs] 657535.473: [GC 657535.473: [ParNew: 331734K->20282K(353920K), 0.0259480 secs] 645147K->333695K(878208K), 0.0261670 secs] [Times: user=0.11 sys=0.00, real=0.02 secs] .... .... 688346.765: [GC [1 CMS-initial-mark: 485248K(524288K)] 515694K(878208K), 0.0343730 secs] [Times: user=0.03 sys=0.00, real=0.04 secs] 688346.800: [CMS-concurrent-mark-start] 688347.964: [CMS-concurrent-mark: 1.083/1.164 secs] [Times: user=2.52 sys=0.09, real=1.16 secs] 688347.964: [CMS-concurrent-preclean-start] 688347.969: [CMS-concurrent-preclean: 0.004/0.005 secs] [Times: user=0.00 sys=0.01, real=0.01 secs] 688347.969: [CMS-concurrent-abortable-preclean-start] CMS: abort preclean due to time 688352.986: [CMS-concurrent-abortable-preclean: 2.351/5.017 secs] [Times: user=3.83 sys=0.38, real=5.01 secs] 688352.987: [GC[YG occupancy: 297806 K (353920 K)]688352.987: [Rescan (parallel) , 0.1815250 secs]688353.169: [weak refs processing, 0.0312660 secs] [1 CMS-remark: 485248K(524288K)] 783055K(878208K), 0.2131580 secs] [Times: user=1.13 sys =0.00, real=0.22 secs] 688353.201: [CMS-concurrent-sweep-start] 688353.903: [CMS-concurrent-sweep: 0.660/0.702 secs] [Times: user=0.91 sys=0.07, real=0.70 secs] 688353.903: [CMS-concurrent-reset-start] 688353.912: [CMS-concurrent-reset: 0.008/0.008 secs] [Times: user=0.01 sys=0.00, real=0.01 secs] 688354.243: [GC 688354.243: [ParNew: 344928K->30151K(353920K), 0.0305020 secs] 681955K->368044K(878208K), 0.0308880 secs] [Times: user=0.15 sys=0.00, real=0.03 secs] .... .... 688943.029: [GC 688943.029: [ParNew: 336531K->17143K(353920K), 0.0237360 secs] 813250K->494327K(878208K), 0.0241260 secs] [Times: user=0.10 sys=0.00, real=0.03 secs] 688950.620: [GC 688950.620: [ParNew: 331767K->22442K(353920K), 0.0344110 secs] 808951K->499996K(878208K), 0.0347690 secs] [Times: user=0.11 sys=0.00, real=0.04 secs] 688956.596: [GC 688956.596: [ParNew: 337064K->37809K(353920K), 0.0488170 secs] 814618K->515896K(878208K), 0.0491550 secs] [Times: user=0.18 sys=0.04, real=0.05 secs] 688961.470: [GC 688961.471: [ParNew (promotion failed): 352433K->332183K(353920K), 0.1862520 secs]688961.657: [CMS I suspect this problem has something to do with the last line in the log (I've added some "...." in order to skip some lines that were not interesting). The fact that the server stayed in the hung state for 2 hours (probably trying to GC and compact the old generation) seems quite strange to me. Also, the gc log stops suddenly with that message and nothing else gets printed any more, probably because the VM Thread gets into some sort of infinite loop (or something that takes 2+ hours).

• Decode html tag so that it can be read when it goes back to the server more specifically the controller

  My engine is Aspx. How can I decode/encode the html tags that is in my text box. I have the html tag to make it more readable. I tried the ValidationRequest and the htmlDecode(freqQuestion.Answer) but no luck. I just keep getting the same message. Server Error in '/Administrator' Application. A potentially dangerous Request.Form value was detected from the client (QuestionAnswer="...ics Phone:123-456-7890 Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted.

• Node.js vs PHP processing speed

  - by Cody Craven

  I've been looking into node.js recently and wanted to see a true comparison of processing speed for PHP vs Node.js. In most of the comparisons I had seen, Node trounced Apache/PHP set ups handily. However all of the tests were small 'hello worlds' that would not accurately reflect any webpage's markup. So I decided to create a basic HTML page with 10,000 hello world paragraph elements. In these tests Node with Cluster was beaten to a pulp by PHP on Nginx utilizing PHP-FPM. So I'm curious if I am misusing Node somehow or if Node is really just this bad at processing power. Note that my results were equivalent outputting "Hello world\n" with text/plain as the HTML, but I only included the HTML as it's closer to the use case I was investigating. My testing box: Core i7-2600 Intel CPU (has 8 threads with 4 cores) 8GB DDR3 RAM Fedora 16 64bit Node.js v0.6.13 Nginx v1.0.13 PHP v5.3.10 (with PHP-FPM) My test scripts: Node.js script var cluster = require('cluster'); var http = require('http'); var numCPUs = require('os').cpus().length; if (cluster.isMaster) { // Fork workers. for (var i = 0; i < numCPUs; i++) { cluster.fork(); } cluster.on('death', function (worker) { console.log('worker ' + worker.pid + ' died'); }); } else { // Worker processes have an HTTP server. http.Server(function (req, res) { res.writeHead(200, {'Content-Type': 'text/html'}); res.write('<html>\n<head>\n<title>Speed test</title>\n</head>\n<body>\n'); for (var i = 0; i < 10000; i++) { res.write('<p>Hello world</p>\n'); } res.end('</body>\n</html>'); }).listen(80); } This script is adapted from Node.js' documentation at http://nodejs.org/docs/latest/api/cluster.html PHP script <?php echo "<html>\n<head>\n<title>Speed test</title>\n</head>\n<body>\n"; for ($i = 0; $i < 10000; $i++) { echo "<p>Hello world</p>\n"; } echo "</body>\n</html>"; My results Node.js $ ab -n 500 -c 20 http://speedtest.dev/ This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking speedtest.dev (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Finished 500 requests Server Software: Server Hostname: speedtest.dev Server Port: 80 Document Path: / Document Length: 190070 bytes Concurrency Level: 20 Time taken for tests: 14.603 seconds Complete requests: 500 Failed requests: 0 Write errors: 0 Total transferred: 95066500 bytes HTML transferred: 95035000 bytes Requests per second: 34.24 [#/sec] (mean) Time per request: 584.123 [ms] (mean) Time per request: 29.206 [ms] (mean, across all concurrent requests) Transfer rate: 6357.45 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.2 0 2 Processing: 94 547 405.4 424 2516 Waiting: 0 331 399.3 216 2284 Total: 95 547 405.4 424 2516 Percentage of the requests served within a certain time (ms) 50% 424 66% 607 75% 733 80% 813 90% 1084 95% 1325 98% 1843 99% 2062 100% 2516 (longest request) PHP/Nginx $ ab -n 500 -c 20 http://speedtest.dev/test.php This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking speedtest.dev (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Finished 500 requests Server Software: nginx/1.0.13 Server Hostname: speedtest.dev Server Port: 80 Document Path: /test.php Document Length: 190070 bytes Concurrency Level: 20 Time taken for tests: 0.130 seconds Complete requests: 500 Failed requests: 0 Write errors: 0 Total transferred: 95109000 bytes HTML transferred: 95035000 bytes Requests per second: 3849.11 [#/sec] (mean) Time per request: 5.196 [ms] (mean) Time per request: 0.260 [ms] (mean, across all concurrent requests) Transfer rate: 715010.65 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.2 0 1 Processing: 3 5 0.7 5 7 Waiting: 1 4 0.7 4 7 Total: 3 5 0.7 5 7 Percentage of the requests served within a certain time (ms) 50% 5 66% 5 75% 5 80% 6 90% 6 95% 6 98% 6 99% 6 100% 7 (longest request) Additional details Again what I'm looking for is to find out if I'm doing something wrong with Node.js or if it is really just that slow compared to PHP on Nginx with FPM. I certainly think Node has a real niche that it could fit well, however with these test results (which I really hope I made a mistake with - as I like the idea of Node) lead me to believe that it is a horrible choice for even a modest processing load when compared to PHP (let alone JVM or various other fast solutions). As a final note, I also tried running an Apache Bench test against node with $ ab -n 20 -c 20 http://speedtest.dev/ and consistently received a total test time of greater than 0.900 seconds.

• PHP Email Form Sending Random Text

  - by Doug

  Hi, I did a webpage for a client that involved a series of text boxes asking for specific information such as a person's name, e-mail address, company, etc. Along with a button that would e-mail the information to my client. Whenever I tested the button it seemed to work perfectly, I uploaded the page and thought I was done. But, the other day my client got this email from the site: Name: rfhopzdgmx rfhopzdgmx Email: [email protected] Company: zUDXatAfoDvQrdH Mailing Address: AaSsXklqpHIsoCNcei gXsimMPRBYZqq vGLvZraZNdpOAV, ChsmuibE PoKzaSCubXPRI Home Phone: CIJbIfjMfjIaTqAlD Work Phone: JFLZBOvru Cell Phone: XlFJTTFGiTTiiFQfy Fax: UEJMOVZodWPkKxew Comments: sPvSCE hgetwoguderu,* [url=http://atyktjlxcznl.com/]atyktjlxcznl[/url], [link=http://nudvfcehwpyg.com/]nudvfcehwpyg[/link], http://lvvwkbzbhnzp.com/ Note: The * line contained HTML link code, I just don't know how to get this site to show it. Here is the PHP code in the site for the e-mail button. <?php //This Sends A Formatted Text Email Using The Text Boxes if ($_POST['submit']){ //This Gets The Form Data $fname = $_POST['fName']; $lname = $_POST['lName']; $email = $_POST['email']; $company = $_POST['co']; $address1 = $_POST['address1']; $address2 = $_POST['address2']; $city = $_POST['city']; $state = $_POST['state']; $zip = $_POST['zip']; $homep = $_POST['homeP']; $workp = $_POST['workP']; $cellp = $_POST['cellP']; $fax = $_POST['fax']; $comments = $_POST['txaOutputField']; //echo "<script language = 'javascript'>alert('YAY');</script>"; if ($fname && $lname && $email && $comments){ //Check If Required Fields Are Filled //This Sets The SMTP Configuration In php.ini ini_set("SMTP", "smtp.2ndsourcewire.com"); //This Replaces Any Blank Fields With 'None's if ($company == ""){ $company = "None"; } if ($address1 == ""){ $address1 = "None"; } if ($city == ""){ $city = "None"; } if ($state == ""){ $state = "None"; } if ($zip == ""){ $zip = "None"; } if ($homep == ""){ $homep = "None"; } if ($workp == ""){ $workp = "None"; } if ($cellp == ""){ $cellp = "None"; } if ($fax == ""){ $fax = "None"; } //This Creates The Variables Necessary For The Email $to = "CLIENT EMAIL WHICH I'M CENSORING"; $subject = "Email from 2ndSourceWire.com"; $from = "From: [email protected]"; $secondEmail = "MY EMAIL WHICH I'M ALSO CENSORING"; if ($address2 == ""){ $body = "Name: $fname $lname\n". "Email: $email\n". "Company: $company\n\n". "Mailing Address:\n". "$address1\n". "$city, $state $zip\n\n". "Home Phone: $homep\n". "Work Phone: $workp\n". "Cell Phone: $cellp\n". "Fax: $fax\n\n". "Comments:\n". "$comments"; } else { $body = "Name: $fname $lname\n". "Email: $email\n". "Company: $company\n\n". "Mailing Address:\n". "$address1\n". "$address2\n". "$city, $state $zip\n\n". "Home Phone: $homep\n". "Work Phone: $workp\n". "Cell Phone: $cellp\n". "Fax: $fax\n\n". "Comments:\n". "$comments"; } //This Sends The Email mail($to, $subject, $body, $from); mail($secondEmail, $subject, $body, $from); echo "<script language = 'javascript'>alert('The email was sent successfully.');</script>"; } else { //The Required Fields Are Not Filled echo "<script language = 'javascript'>alert('Please fill your first name, last name, email address, and your comment or question.');</script>"; } } ? I'm a little dumbfounded on how this happened, the client mentioned a couple e-mails of this, so I don't think it is a random glitch. Also, the e-mail address was formatted like an e-mail address, so someone or some program was interpreting the labels next to each text box. I also noticed that the first and last names entered are the same word, even though they were in different text boxes, I'm thinking its some spam program, but wouldn't they try to advertise something and make money, rather than just spouting out random text? Also, the comments section makes no sense to me at all, the links goto nowhere and they're all perfectly formatted, a random person just screwing around wouldn't know those tags, and a programmer doing it wouldn't bother with it, but also neither would a program. I have no idea what caused this or how to fix it, I'm drawing a blank here. Anyone have any ideas?

• Problem deploying servlets in JBoss 5.1 on eclipse.

  - by Jeremy Goodell

  Yesterday I created a simple image servlet and attempted to deploy it. I am getting an error on JBoss startup, and then further errors on trying to invoke the servlet. I spent about 8 hours yesterday searching the web for answers and trying different scenarios. I ended up making my JBoss problems worse and then fixing them, but I never did get the servlet to work. The servlet is com.controller.MyImageServlet, and looks like this: package com.controller; import javax.servlet.http.*; /** * Servlet implementation class MyImageServlet */ public class MyImageServlet extends HttpServlet { private static final long serialVersionUID = 1L; public MyImageServlet() { super(); } // Process the HTTP Get request public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { /* ... */ } } The tags I've added to web.xml looks like this: <servlet> <servlet-name>ImageServlet</servlet-name> <servlet-class>com.controller.MyImageServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>ImageServlet</servlet-name> <url-pattern>/CERTIMAGE/*</url-pattern> </servlet-mapping> On server startup, this is the only indication in the log that something is amiss: 01:59:25,328 WARN [JAXWSDeployerHookPreJSE] Cannot load servlet class: com.controller.MyImageServlet When I try the URL pattern (http://localhost:9980/CERTIMAGE/1), I get the following stack trace in the log (and in the Browser): 01:59:39,640 INFO [[/]] Marking servlet ImageServlet as unavailable 01:59:39,640 ERROR [[ImageServlet]] Allocate exception for servlet ImageServlet java.lang.ClassNotFoundException: com.controller.MyImageServlet at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) at org.jboss.web.tomcat.service.TomcatInjectionContainer.newInstance(TomcatInjectionContainer.java:262) at org.jboss.web.tomcat.service.TomcatInjectionContainer.newInstance(TomcatInjectionContainer.java:256) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1006) at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:777) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:129) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:190) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:92) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.process(SecurityContextEstablishmentValve.java:126) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.invoke(SecurityContextEstablishmentValve.java:70) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:158) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:330) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:829) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:598) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619) If I try the URL pattern again, I get the following message in the log: 09:33:32,390 INFO [[ImageServlet]] Servlet ImageServlet is currently unavailable I have verified that MyImageServlet.class is in the WAR at WEB-INF/classes/com/controller/images. As a matter of fact, I even added some code to one of my JSPs to attempt to instantiate the Servlet and call the doGet method. This actually works and outputs the correct debug sequences to the log indicating that the Servlet constructor and doGet methods were called. I also tried following some instructions for creating/deploying a very simple HelloWorld servlet, and that has exactly the same problem. Note that web.xml already contained a servlet put there by JBoss: org.jboss.web.tomcat.service.StatusServlet -- that Servlet does not give any errors in the log. As an experiment, I removed ".web" from that path and ended up getting exactly the same error as I'm getting on my Servlet. So it would appear that JBoss is not able to locate my Servlet given the specified path. Just for kicks, I've tried all sorts of other paths, like just plain MyImageServlet, controller.MyImageServlet, and more. Also, the servlet was originally named ImageServlet, but I attempted the name change thinking maybe there was some conflict with an existing ImageServlet. In all cases, the behavior is the same. After all of my research yesterday, I would say that this appears to be a problem with the JBoss servlet container, and I also learned that JBoss 5.1.0.GA should come bundled with a tomcat servlet container. I installed JBoss on my PC (Windows XP) myself less than 2 months ago (from jboss.org) and used it pretty much as is. Note that I am running on JDK 1.6, so I did use the jboss-jdk6 installation version. I am running on Windows, but I also deploy to a Linux virtual dedicated server. I deployed the current version of my program, including the servlet to the Linux box, but I get the exact same errors. I'm reluctant to just try reinstalling JBoss, since it's hard to place the blame on the JBoss installation when I get the same errors on two completely different installations. I am a bit suspicious of the bundled tomcat servlet container, because using eclipse, I haven't been able to locate any indication that there is a tomcat bundled into JBoss. I did locate servlet-api.jar in the JBoss common/lib directory. This is on the eclipse build path. One possibly useful note: I had previously used a standalone tomcat server for other projects using the same eclipse, so maybe it's some sort of eclipse issue? But, as I said, I do get the same errors when I deploy to the Linux server, and that deployment process just involves ftping files to the server and then putting them into the deployed war package and restarting JBoss. Thanks for any help you can provide.

• How do I drag and drop between two listboxes in XUL?

  - by pc1oad1etter

  I am trying to implement drag and drop between two listboxes. I have a few problems 1) I am not detecting any drag events of any kind from the source list box/ I do not seem to be able to drag from it 2) I can drag from my desktop to the target listbox and I am able to detect 'dragenter' 'dragover' and 'dragexit' events. I am noticing that the event parameter is undefined in my 'dragenter' callback - is this a problem? 3) I cannot figure out how to complete the drag and drop operation. From https://developer.mozilla.org/En/DragDrop/Drag_Operations#Performing_... "If the mouse was released over an element that is a valid drop target, that is, one that cancelled the last dragenter or dragover event, then the drop will be successful, and a drop event will fire at the target. Otherwise, the drag operation is cancelled and no drop event is fired." This seems to be referring to a 'drop' event, though there is not one listed at https://developer.mozilla.org/en/XUL/Events . I can't seem to detect the end of the drag in order to call one of the example 'doDrop()' functions that I find on MDC. My example, so far: http://pastebin.mozilla.org/713676 <?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <window xmlns="http://www.mozilla.org/keymaster/gatekeeper/ there.is.only.xul" onload="initialize();"> <vbox> <hbox> <vbox> <description>List1</description> <listbox id="source" draggable="true"> <listitem label="1"/> <listitem label="3"/> <listitem label="4"/> <listitem label="5"/> </listbox> </vbox> <vbox> <description>List2</description> <listbox id="target" ondragenter="onDragEnter();"> <listitem label="2"/> </listbox> </vbox> </hbox> </vbox> <script type="application/x-javascript"> <![CDATA[ function initialize(){ jsdump('adding events'); var origin = document.getElementById("source"); origin.addEventListener("drag", onDrag, false); origin.addEventListener("dragdrop", onDragDrop, false); origin.addEventListener("dragend", onDragEnd, false); origin.addEventListener("dragstart", onDragStart, false); var target = document.getElementById("target"); target.addEventListener("dragenter", onDragEnter, false); target.addEventListener("dragover", onDragOver, false); target.addEventListener("dragexit", onDragExit, false); target.addEventListener("drop", onDrop, false); target.addEventListener("drag", onDrag, false); target.addEventListener("dragdrop", onDragDrop, false); } function onDrag(){ jsdump('onDrag'); } function onDragDrop(){ jsdump('onDragDrop'); } function onDragStart(){ jsdump('onDragStart'); } function onDragEnd(){ jsdump('onDragEnd'); } function onDragEnter(event){ //debugger; if(event){ jsdump('onDragEnter event.preventDefault()'); event.preventDefault(); }else{ jsdump("event undefined in onDragEnter"); } } function onDragExit(){ jsdump('onDragExit'); } function onDragOver(event){ //debugger; if(event){ //jsdump('onDragOver event.preventDefault()'); event.preventDefault(); }else{ jsdump("event undefined in onDragOver"); } } function onDrop(event){ jsdump('onDrop'); var data = event.dataTransfer.getData("text/plain"); event.target.textContent = data; event.preventDefault(); } function jsdump(str) { Components.classes['[email protected]/consoleservice;1'] .getService(Components.interfaces.nsIConsoleService) .logStringMessage(str); } ]]> </script> </window>

• Creating a list of most popular posts of the past week - Wordpress

  - by Gary Woods

  I have created a widget for my Wordpress platform that displays the most popular posts of the week. However, there is an issue with it. It counts the most popular posts from Monday, not the past 7 days. For instance, this means that on Tuesday, it will only include posts from Tuesday and Monday. Here is my widget code: <?php class PopularWidget extends WP_Widget { function PopularWidget(){ $widget_ops = array('description' => 'Displays Popular Posts'); $control_ops = array('width' => 400, 'height' => 300); parent::WP_Widget(false,$name='ET Popular Widget',$widget_ops,$control_ops); } /* Displays the Widget in the front-end */ function widget($args, $instance){ extract($args); $title = apply_filters('widget_title', empty($instance['title']) ? 'Popular This Week' : $instance['title']); $postsNum = empty($instance['postsNum']) ? '' : $instance['postsNum']; $show_thisweek = isset($instance['thisweek']) ? (bool) $instance['thisweek'] : false; echo $before_widget; if ( $title ) echo $before_title . $title . $after_title; ?> <?php $additional_query = $show_thisweek ? '&year=' . date('Y') . '&w=' . date('W') : ''; query_posts( 'post_type=post&posts_per_page='.$postsNum.'&orderby=comment_count&order=DESC' . $additional_query ); ?> <div class="widget-aligned"> <h3 class="box-title">Popular Articles</h3> <div class="blog-entry"> <ol> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <li><h4 class="title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h4></li> <?php endwhile; endif; wp_reset_query(); ?> </ol> </div> </div> <!-- end widget-aligned --> <div style="clear:both;"></div> <?php echo $after_widget; } /*Saves the settings. */ function update($new_instance, $old_instance){ $instance = $old_instance; $instance['title'] = stripslashes($new_instance['title']); $instance['postsNum'] = stripslashes($new_instance['postsNum']); $instance['thisweek'] = 0; if ( isset($new_instance['thisweek']) ) $instance['thisweek'] = 1; return $instance; } /*Creates the form for the widget in the back-end. */ function form($instance){ //Defaults $instance = wp_parse_args( (array) $instance, array('title'=>'Popular Posts', 'postsNum'=>'','thisweek'=>false) ); $title = htmlspecialchars($instance['title']); $postsNum = htmlspecialchars($instance['postsNum']); # Title echo '<p><label for="' . $this->get_field_id('title') .
