  • Unresponsive Clojure REPL after exception

    - by Hendekagon
    If I start a REPL and then do something that throws an exception like (use 'non-existent-thing) ** then after that the REPL ceases to evaluate anything I enter. Is there a special key I can press to make it turn round, face me, uncross its arms and listen once more ? Or must I ctrl-d, restart, type everything up to where I was and get it right this time ? ** which results in: Exception in thread "Thread-1" java.lang.RuntimeException: java.io.FileNotFoundException: Could not locate non_existent_thing__init.class or non_existent_thing.clj on classpath: (NO_SOURCE_FILE:0)

  • JAVA - Strange problem (probably thread problem) with JTable & Model

    - by Stefanos Kargas
    I am using 2 Tables (JTable) with their DefaultTableModels. The first table is already populated. The second table is populated for each row of the first table (using an SQL Query). My purpose is to export every line of the first table with it's respective lines of the second in an Excel File. I am doing it with a for (for each line of 1st table), in which I write a line of the 1st table in the Excel File, then I populate the 2nd table (for this line of 1st Table), I get every line from the Table (from it's Model actually) and put it in the Excel File under the current line of 1st table. This means that if I have n lines in first table I will clear and populate again the second table n times. All this code is called in a seperate thread. THE PROBLEM IS: Everything works perfectly fine ecxept that I am getting some exceptions. The strange thing is that I'm not getting anything false in my result. The Excel file is perfect. Some of the lines of the exceptions are: Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 0 = 0 at java.util.Vector.elementAt(Vector.java:427) at javax.swing.table.DefaultTableModel.getValueAt(DefaultTableModel.java:632) at javax.swing.JComponent.paint(JComponent.java:1017) at javax.swing.RepaintManager.paint(RepaintManager.java:1220) at javax.swing.RepaintManager.paintDirtyRegions(RepaintManager.java:803) I am assuming that the problem lies in the fact that the second table needs some more time to be populated before I try to get any data from it. That's why I see RepaintManager and paintDirtyRegions in my exceptions. Another thing I did is that I ran my program in debug mode and I put a breakpoint after each population of the 2nd table. Then I pressed F5 to continue for each population of 2nd table and no exception appeared. The program came to it's end without any exceptions. This is another important fact that tells me that maybe in this case I gave the table enough time to be populated. Of course you will ask me: If your program works fine, why do you care about the exceptions? I care for avoiding any future problems and I care to have a better understanding of Java and Java GUI and threads. Why do you depend on a GUI component (and it's model) to get your information and why don't you recreate the resultset that populates your tables using an SQL Query and get your info from the resultset? That would be the best and the right way. The fact is that I have the tables code ready and it was easier for me to just get the info from them. But the right way would be to get everything direct from database. Anyway what I did brought out my question, and answering it would help me understand more things about java. So I posted it.

  • How does the hash part in hash maps work?

    - by sub
    So there is this nice picture in the hash maps article on Wikipedia: Everything clear so far, except for the hash function in the middle. How can a function generate the right index from any string? Are the indexes integers in reality too? If yes, how can the function output 1 for John Smith, 2 for Lisa Smith, etc.?

  • Basic SQL Select in Postgresql fails

    - by Rhubarb
    I am doing a select * on a postgresql table, and everything looks good. But if I do: SELECT Name from People It says: ERROR: column People.Name does not exist SQL state: 42703 Character: 8 But the name column shows up during select *. I've tried: SELECT People.Name from People as well, with the same result. Am I missing something? It should be pretty easy to do this in any other database.

  • SQLAlchemy returns tuple not dictionary

    - by Ivan
    Hi everyone, I've updated SQLAlchemy to 0.6 but it broke everything. I've noticed it returns tuple not a dictionary anymore. Here's a sample query: query = session.query(User.id, User.username, User.email).filter(and_(User.id == id, User.username == username)).limit(1) result = session.execute(query).fetchone() This piece of code used to return a dictionary in 0.5. My question is how can I return a dictionary?

  • What's the case when using software licensed under GPL or LGPL

    - by Johnas
    With everything legal and in line with the ethical questions in software development, is it allowed to use an open source product in my software that I charge a fee for when selling? Scenario: I've developed an PHP Content Management System (CMS) and use some Linux executables licensed under GPL or LGPL in my CMS to accomplish various tasks like image editing. I'm selling the CMS and also including the executables when I deliver the product. I do not edit the source code of the GPL software, just using it.

  • How can I pin a div in my sidebar column to the bottom?

    - by vg1890
    I have a simple two column layout with a footer at the bottom. When the content in the sidebar is taller than the content in the main column, everything looks great. But when the height of the main column is greater than the sidebar, I need the sidebar to grow to the same height as the main column and for the last <div> in the sidebar to be pinned to the very bottom. Here's my sample code: http://jsfiddle.net/mqnML/1/

  • How to start a ColorAnimation from a MultiTrigger in a ControlTemplate ?

    - by banzai
    Hi all I have the following ControlTemplate for a WPF TabItem: <ControlTemplate x:Key="DefaultTabItemTemplate" TargetType="{x:Type TabItem}"> <ControlTemplate.Resources> <SolidColorBrush x:Key="UnselectedForegroundBrush" Color="#414141" /> <!-- Unique color for this template --> <SolidColorBrush x:Key="SelectedForegroundBrush" Color="#457581" /> <!-- Unique color for this template --> <SolidColorBrush x:Key="MouseOverTextBrush" x:Name="local_MouseOverTextBrush" Color="#FFF2F2F2"/> </ControlTemplate.Resources> <Grid> <Border Name="Border" MinHeight="30" Margin="0,0,0,-1" Background="{DynamicResource TabControlBackgroundBrush}" BorderBrush="{DynamicResource ndt_DisabledForegroundBrush}" BorderThickness="1,1,1,1" CornerRadius="0,0,0,0" > <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center" HorizontalAlignment="Center" TextElement.FontStretch="UltraExpanded" TextElement.FontWeight="UltraBlack" ContentSource="Header" Margin="12,2,12,2" RecognizesAccessKey="True" /> </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="Panel.ZIndex" Value="2" /> <Setter TargetName="Border" Property="Background" Value="{DynamicResource ndt_TabControlBackgroundBrush}" /> <Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" /> <Setter TargetName="ContentSite" Property="TextElement.Foreground" Value="{StaticResource SelectedForegroundBrush}" /> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter TargetName="Border" Property="Background" Value="{DynamicResource ndt_DisabledBackgroundBrush}" /> <Setter TargetName="ContentSite" Property="TextElement.Foreground" Value="{DynamicResource ndt_DarkGray}" /> <Setter Property="Foreground" Value="{DynamicResource ndt_DisabledForegroundBrush}" /> </Trigger> <MultiTrigger> <MultiTrigger.Conditions> <Condition Property="IsMouseOver" Value="True" /> <Condition Property="IsSelected" Value="False" /> </MultiTrigger.Conditions> <Setter TargetName="Border" Property="Background" Value="{DynamicResource ndt_NavigationAreaBrush}" /> <Setter TargetName="ContentSite" Property="TextElement.Foreground" Value="{DynamicResource MouseOverTextBrush}" /> </MultiTrigger> </ControlTemplate.Triggers> </ControlTemplate> Everything works fine so far. The MultiTrigger at the end of the template defines a mouse over effect for not selected TabItems. Now I thought the change in color for this mouse over effect looks a bit brash so let´s animate it with a ColorAnimation. But don´t count the chickens before they hatch - everything I tried didn´t work. Maybe I oversee the obvious - but how to achieve this feat ? Thanks in advance banzai

  • [IE] Remove the complete styling of an HTML button/submit

    - by Saif Bechan
    Is there a way of completely removing the styling of a button in Internet Explorer? I use a css sprite for my button, and everything looks ok. But when I click the button, it moves to the top a little, it makes it look out of shape. Is there a css click state, or mousedown? I don't know what triggers that state. I know it's not a really big deal, but sometimes it's the small things that matter.

  • C# mvc 3 using selectlist with selected value in view

    - by Rob
    I'm working on a MVC3 web application. I want a list of categories shown when editing a blo from whe applications managements system. In my viewmodel i've got the following property defined for a list of selectlistitems for categories. /// <summary> /// The List of categories /// </summary> [Display(Name = "Categorie")] public IEnumerable<SelectListItem> Categories { get; set; } The next step, my controller contains the following edit action where the list of selectlistitems is filled from the database. public ActionResult Edit(Guid id) { var blogToEdit = _blogService.First(x => x.Id.Equals(id)); var listOfCategories = _categorieService.GetAll(); var selectList = listOfCategories.Select(x =>new SelectListItem{Text = x.Name, Value = x.Id.ToString(), Selected = x.Id.Equals(blogToEdit.Category.Id)}).ToList(); selectList.Insert(0, new SelectListItem{Text = Messages.SelectAnItem, Value = Messages.SelectAnItem}); var viewModel = new BlogModel { BlogId = blogToEdit.Id, Active = blogToEdit.Actief, Content = blogToEdit.Text, Title = blogToEdit.Titel, Categories = selectList //at this point i see the expected item being selected //Categories = new IEnumerable<SelectListItem>(listOfCategories, "Id", "Naam", blogToEdit.CategorieId) }; return View(viewModel); } When i set a breakpoint just before the view is being returned, i see that the selectlist is filled as i expected. So at this point everything seems to be okay. The viewmodel is filled entirely correct. Then in my view (i'm using Razor) i've got the following two rules which are supposed to render the selectlist for me. @Html.LabelFor(m => m.Categories) @Html.DropDownListFor(model=>model.Categories, Model.Categories, Model.CategoryId) @Html.ValidationMessageFor(m => m.Categories) When I run the code and open the view to edit my blog, I can see all the correct data. Also the selectlist is rendered correctly, but the item i want to be selected lost it's selection. How can this be? Until the point the viewmodel is being returned with the view everything is okay. But when i view the webpage in the browser, the selectlist is there only with out the correct selection. What am I missing here? Or doing wrong?

  • Pros and cons of escaping strategies in symfony

    - by zergu
    I am still not sure in that matter. While turned on we're quite safe but some other problems appear (with passing template variables or counting characters). On the other hand we have magic turned off, everything is clear, but we have to manually escape every variable (that come from untrusted source) in templates. By the way, non-magic solution is used in Ruby-on-Rails. So the question is: when starting a new project in symfony do you disable escaping_strategy and why?

  • Reliability of UDP on localhost

    - by Bryan Ward
    I know that UDP is inherently unreliable, but when connecting to localhost I would expect the kernel handles the connection differently since everything can be handled internally. So in this special case, is UDP considered a reliable protocol, or will the kernel still potentially junk some packets if buffers are overrun?

  • FLEX components: updating import statements to move the component into another folder

    - by Patrick
    hi, I've just imported a Flex component into my project. I have a theory question about importing. all the imports statements in the component source files started with "com.subFolder.etc", but I have preferred to move the component folders into "componentName" and to replace all import statements as "componentName.com.subFolder.etc" Is this ok ? Everything works perfectly, but I was wondering if the method is correct. thanks
