  • Virtual destructors for interfaces.

    - by wowus
    Do interfaces need a virtual destructor, or is the auto-generated one fine? For example, which of the following two code snippets is best, and why? class Base { public: virtual void foo() = 0; virtual ~Base() {} }; OR... class Base { public: virtual void foo() = 0; };

  • Obfuscating a Magento module

    - by Elzo Valugi
    I've been asked to protect a Magento module through obfuscation. I never used PHP obfuscation packages but I know how they work and I forsee some issues in obfuscating a module that is very string and xml dependant: /etc/config.xml registers harcoded class names and paths auto-loading is heavily used I cannot imagine how to automatically obfuscate a class name that will be called later by Mage::getModel('my/module'). Any recommendations?

  • Why manual memory management?

    - by user333639
    Are there any plans for auto memory management? What are the advantanges of manually managing memory...does it conserve memory in the long run? I have noticed in .Net Windows Applications - they are very sluggish - is this partly due to the garbage collector not working correctly?

  • Why does VerticalScrollBarVisibility not work in a style in Silverlight?

    - by Edward Tanguay
    VerticalScrollBarVisibility works when I define it inline like this: <UserControl x:Class="TestScrollBar.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"> <UserControl.Resources> <Style TargetType="TextBox" x:Key="EditListContainerContentMultiLineTwoColumn"> <Setter Property="AcceptsReturn" Value="True"/> <Setter Property="Width" Value="400"/> <Setter Property="Height" Value="300"/> <Setter Property="IsReadOnly" Value="False"/> <Setter Property="Margin" Value="0 0 0 20"/> <Setter Property="HorizontalAlignment" Value="Left"/> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White" Margin="10"> <StackPanel HorizontalAlignment="Left"> <TextBox Text="this is a test" Style="{StaticResource EditListContainerContentMultiLineTwoColumn}" VerticalScrollBarVisibility="Auto" /> </StackPanel> </Grid> </UserControl> But when I put VerticalScrollBarVisibility in a style, it shows me a blank screen: <UserControl x:Class="TestScrollBar.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"> <UserControl.Resources> <Style TargetType="TextBox" x:Key="EditListContainerContentMultiLineTwoColumn"> <Setter Property="VerticalScrollBarVisibility" Value="Auto"/> <Setter Property="AcceptsReturn" Value="True"/> <Setter Property="Width" Value="400"/> <Setter Property="Height" Value="300"/> <Setter Property="IsReadOnly" Value="False"/> <Setter Property="Margin" Value="0 0 0 20"/> <Setter Property="HorizontalAlignment" Value="Left"/> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White" Margin="10"> <StackPanel HorizontalAlignment="Left"> <TextBox Text="this is a test" Style="{StaticResource EditListContainerContentMultiLineTwoColumn}" /> </StackPanel> </Grid> </UserControl> In WPF it works works fine. How can I get VerticalScrollBarVisibility to work in a style?

    I've an access database table with 3 fields : Purchase date Warranty time Warranty expiry Warranty time has 1, 2, 3, 4, 5 in it which corresponds to years.

  • Why is my web page left-aligned on iPad?

    - by Andrew
    I recently built a site and centered it using margin: 0 auto. I also wrapped elements in a .wrapper class with a width set to 960px and then had the parent element extend across the whole browser. When I view the Brands screen on an iPad though, the site is left-aligned and does not extend across the whole window. Any thoughts to why this might be happening, and how to correct it? See below for a screenshot:

  • Navbar Menu Trouble shoot

    - by Nabeel M
    So I wanted to create the fixed nav bar on top of the page. Instead of creating nav bar with ordered list, I used the following approach: <header> <div class="nav"> <img src="images/logo_ab.png" alt="AurinBioTech Logo"/> <a href="index.html">Home</a> <a href="#">About</a> <a href="#">Team</a> <a href="#">Science</a> <a href="#">Need</a> <a href="#">Pipeline</a> <a href="#">Contact</a> </div> </header> CSS: header .nav { margin-top:100px; width:100%; height:10%; text-align:center; padding-top:2%; margin:0 auto; position:fixed; top:0; } header .nav a { font-size: 2em; padding-left: 15px; padding-right: 15px; color:rgb(1, 1, 1); text-decoration: none; font-family: 'Bebas'; } header .nav a:hover { color:white; background-color: #404040; border-radius:5px; padding:0 auto; } header .nav a:active{ background-color: #404040; border-radius:5px; text-decoration:overline; } header .nav img { width:260px; height:65px; padding-right:4em; } The reason I used this approach is because I wanted to use logo image next to the nav bar so it would align properly in the same line. Now the problem is that I need to add sub-menus under Science and Pipeline heading. Since I didn't use UL or LI, how can I add sub-menus under those heading. OR, can you tell me any other way to create a NAV bar that shows the logo as well. so it would be LOGO and MENUS on the same line. Great thanks in advance.

  • Generate XSD from 2005 SQL Server Database

    - by Robert Finlayson
    What is the easiest method to generate an XSD schema from a 2005 SQL Server Database? Would it be possible to generate one XSD schema for the entire Database (~100 tables)? I searched online and found a SQL example that generates one XSD for the one table: DECLARE @schema xml SET @schema = (SELECT * FROM MyTableName FOR XML AUTO, ELEMENTS, XMLSCHEMA('MyTableNameSchema')) SELECT @schema Outside of SQL Server, is there a third party tool that could generate the XSD file from the 2005 Database?

    - by jon
    I have a flex grid where I have the verticalScrollPolicy="auto".But every time when the scrollbar appears all the columns get pushed to the left, making the columns not align as they should. I tried setting minWidth on all the columns to prevent this, but that doesn't seem to work. Any ideas?

  • Twitter Bootstrap Navbar blocking svg viewBox

    - by user1167650
    I have a navbar fixed to the bottom and I have page that has a title and a giant svg (created by d3.js). I would like the svg to take up the entire screen (whatever is left over), but it always seems to have some part appear behind the bottom nav bar. I've tried: 1) using viewBox to auto-resize, setting the parent div and the svg to be block elements 2) adding padding-bottom to the body element But the svg still appears behind the navbar on wide screen monitors.

    - by Nocturne
    So here's my scenario: I have two projects projectA and projectB. A branchspec auto-integrates projectA to projectB.
