  • Change array that might contain None to an array that contains "" in python

    - by vy32
    I have a python function that gets an array called row. Typically row contains things like: ["Hello","goodbye","green"] And I print it with: print "\t".join(row) Unfortunately, sometimes it contains: ["Hello",None,"green"] Which generates this error: TypeError: sequence item 2: expected string or Unicode, NoneType found Is there an easy way to replace any None elements with ""?

  • Renaming nodes and values with xslt

    - by T.K.
    Hello world, I'm new to xslt, and have a task that I'm not really sure where to go with. I want to rename nodes, but maintain the format all node declarations. In the actual context I'll be applying this to, I'll be doing a series of renames like this, but for the sake of brevity, the sample I've written up only involves renaming one node. I am using XSL 1.0. Input: <variables> <var> <RENAME> a </RENAME> </var> <var RENAME='b'/> <var> <DO_NOT_TOUCH> c </DO_NOT_TOUCH> </var> <var DO_NOT_TOUCH='d'/> </variables> Desired Output: <variables> <var> <DONE> a </DONE> </var> <var DONE='b'/> <var> <DO_NOT_TOUCH> c </DO_NOT_TOUCH> </var> <var DO_NOT_TOUCH='d'/> </variables> My xslt: <xsl:template match="RENAME"> <RENAMED> <xsl:apply-templates select="@*|node()"/> </RENAMED> </xsl:template> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> Current Output <variables> <var> <RENAMED> a </RENAMED> </var> <var RENAME="b"> </var> <var> <DO_NOT_TOUCH> c </DO_NOT_TOUCH> </var> <var DO_NOT_TOUCH="d"> </var> </variables>

  • ListBoxItem height not getting updated

    - by Gili
    Hi, I have a listbox inside another list box, in inner list box listboxitems height may grow or shrink. My problem is that when the inner items shrink the outer list box doesn't re-render its height. Thus - stays with the previous height before the inner list shrinked. I have tried so many things here, among Invalidate of all types, selection and de-selection of the list box item that should be updated and more - nothing helps.... Can anyone pls help me with this? Thanx, Gili

  • WPF: How to properly override the methods when creating custom control

    - by EV
    Hi, I am creating a custom control Toolbox that is derived from ItemsControl. This toolbox is supposed to be filled with icons coming from the database. The definition looks like this: public class Toolbox : ItemsControl { protected override DependencyObject GetContainerForItemOverride() { return new ToolboxItem(); } protected override bool IsItemItsOwnContainerOverride(object item) { return (item is ToolboxItem); } } Toolboxitem is derived from ContentControl. public class ToolboxItem : ContentControl { static ToolboxItem() { FrameworkElement.DefaultStyleKeyProperty.OverrideMetadata(typeof(ToolboxItem), new FrameworkPropertyMetadata(typeof(ToolboxItem))); } } Since the number of icons stored in a database is not known I want to use the data template: <DataTemplate x:Key="ToolBoxTemplate"> <StackPanel> <Image Source="{Binding Path=url}" /> </StackPanel> </DataTemplate> Then I want the Toolbox to use the template. <Toolbox x:Name="NewLibrary" ItemsSource="{Binding}" ItemTemplate="ToolBoxtemplate"> </Toolbox> I'm using ADO.NET entity framework to connect to a database. The code behind: SystemicsAnalystDBEntities db = new SystemicsAnalystDBEntities(); private void Window_Loaded(object sender, RoutedEventArgs e) { NewLibrary.ItemsSource = from c in db.Components select c; } However, there is a problem. When the code is executed, it displays the object from the database (as the ItemSource property is set to the object from the database) and not the images. It does not use the template. When I use the static images source it works in the right way I found out that I need to override the PrepareContainerForItemOverride method.But I don't know how to add the template to it. Thanks a lot for any comments. Additional Information Here is the ControlTemplate for ToolboxItem: <ControlTemplate TargetType="{x:Type s:ToolboxItem}"> <Grid> <Rectangle Name="Border" StrokeThickness="1" StrokeDashArray="2" Fill="Transparent" SnapsToDevicePixels="true" /> <ContentPresenter Content="{TemplateBinding ContentControl.Content}" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" /> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="true"> <Setter TargetName="Border" Property="Stroke" Value="Gray" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate>

  • Peek ahead when iterating an array in PHP 5.2

    - by pako
    Is it possible to "peek ahead" while iterating an array in PHP 5.2? For example, I often use foreach to manipulate data from an array: foreach($array as $object) { // do something } But I often need to peek at the next element while going through the array. I know I could use a for loop and reference the next item by it's index ($array[$i+1]), but it wouldn't work for associative arrays. Is there any elegant solution for my problem, perhaps involving SPL?

  • How to get headers into framework in Xcode?

    - by john146
    I'm trying to build a framework for MacOS in Xcode 3. It looks like it's building everything except the Headers directory according to the layout listed in the Apple documentation. I can't find anything that tells me what settings to use to get the build process to copy the headers into Headers directory in the framework, or alternately where I have to put those files. Any help? Thanks.

  • Use OpenGL ES to create an iPhone painting tool?

    - by Jeff
    Is it feasible to use OpenGL ES to create an iPhone raster graphics editor like SketchBook Mobile(http://usa.autodesk.com/adsk/servlet/pc/item?siteID=123112&id=13872203)? Any related reference(tutorial, sample) you can recommend? Why I try to use OpenGL ES? Because it's hardware accelerated and cross-platform. Thanks in advance!

  • Patterns: Local Singleton vs. Global Singleton?

    - by Mike Rosenblum
    There is a pattern that I use from time to time, but I'm not quite sure what it is called. I was hoping that the SO community could help me out. The pattern is pretty simple, and consists of two parts: A singleton factory, which creates objects based on the arguments passed to the factory method. Objects created by the factory. So far this is just a standard "singleton" pattern or "factory pattern". The issue that I'm asking about, however, is that the singleton factory in this case maintains a set of references to every object that it ever creates, held within a dictionary. These references can sometimes be strong references and sometimes weak references, but it can always reference any object that it has ever created. When receiving a request for a "new" object, the factory first searches the dictionary to see if an object with the required arguments already exits. If it does, it returns that object, if not, it returns a new object and also stores a reference to the new object within the dictionary. This pattern prevents having duplicative objects representing the same underlying "thing". This is useful where the created objects are relatively expensive. It can also be useful where these objects perform event handling or messaging - having one object per item being represented can prevent multiple messages/events for a single underlying source. There are probably other reasons to use this pattern, but this is where I've found this useful. My question is: what to call this? In a sense, each object is a singleton, at least with respect to the data it contains. Each is unique. But there are multiple instances of this class, however, so it's not at all a true singleton. In my own personal terminology, I tend to call the factory method a "global singleton". I then call the created objects "local singletons". I sometimes also say that the created objects have "reference equality", meaning that if two variables reference the same data (the same underlying item) then the reference they each hold must be to the same exact object, hence "reference equality". But these are my own invented terms, and I am not sure that they are good ones. Is there standard terminology for this concept? And if not, could some naming suggestions be made? Thanks in advance...

  • Clickable TextView in Android

    - by Cris
    i'm building an Android App that has many many TextView that i want to be clickable. I've tried to assign to the single TextView the properties android:clickable="true" and android:onClick="clickHandler" and when the app fires the clickHandler(View v) i correctly get, through the v.getId(), the clicked item. What i don't like is to define, for every TextView, the properties android:clickable and android:onClick ... is there something that i can do by code to say: "all the textviews are clickable and click is handled in 'clickHandler' ?" Thanks and greetings c

  • Converting items in Visual Studio project from "links" to copied files

    - by Alan Mendelevich
    Hi, I have a Visual Studio (2008) project where I have some files added as links (through Add Existing Item-Add As Link). Suppose I want to copy this project somewhere else (give it to another developer, release source code, etc.) and I would like to "convert" all these links to actual copies of these files. Is this possible? How can I do this in VS or is there some 3rd party utility to do that? Thanks.

  • Sitecore E-Commerce Module - Discount/Promotional Codes

    - by Zachary Kniebel
    I am working on a project for which I must use Sitecore's E-Commerce Module (and Sitecore 6.5 rev. 120706 - aka 'Update 5') to create a web-store. One of the features that I am trying to implement is a generic promotional/discount code system - customer enters a code at checkout which grants a discount like 'free shipping', '20% off', etc. At the moment, I am looking for some guidance (a high-level solution, a few pseudo-ideas, some references to review, etc) as to how this can be accomplished. Summary: What I am looking for is a way to detect whether or not the user entered a promo code at a previous stage in the checkout line, and to determine what that promo code is, if they did. Progress Thus Far: I have thoroughly reviewed all of the Sitecore E-Commerce Services (SES) documentation, especially "SES Order Line Extension" documentation (which I believe will have to be modified/extended in order to accomplish this task). Additionally, I have thoroughly reviewed the Sitecore Community article Extending Sitecore E-Commerce - Pricing and believe that it may be a useful guide for applying a discount statically, but does not say much in the way of applying a discount dynamically. After reviewing these documents, I have come up with the following possible high-level solution to start from: I create a template to represent a promotional code, which holds all data relevant to the promotion (percent off, free shipping, code, etc). I then create another template (based on the Product Search Group template) that holds a link to an item within a global "Promotional Code" items folder. Next, I use the Product Search Group features of my new template to choose which products to apply the discount to. In the source code for the checkout I create a class that checks if a code has been entered and, if so, somehow carry it through the rest of the checkout process. This is where I get stuck. More Details: No using cookies No GET requests No changing/creating/deleting items in the Sitecore Database during the checkout process (e.g., no manipulation of fields of a discount item during checkout to signal that the discount has been applied) must stay within the scope of C# Last Notes: I will update this post with any more information that I find/progress that I make. I upgrade all answers that are relevant and detailed, thought-provoking, or otherwise useful to me and potentially useful to others, in addition to any high-level answers that serve as a feasible solution to this problem; even if your idea doesn't help me, if I think it will help someone else I will still upgrade it. Thanks, in advance, for all your help! :)

  • How do I turn off automatic saving of a vim file with a ~ suffix

    - by Leonard
    In my environment, I share vim configuration with other developers (and have my own configuration additions as well) in various .vimrc files. Some places in the environment, I edit a file in vim and automagically a copy of that file with a trailing tilde suffix appears. What vim options control this? I'd like to turn the feature off, as it just clutters up my directories and spoils auto-completion on the command line. Thanks.
