  • How can I bind a LinkedList as ItemSource to ListView in WPF XAML?

    - by Jonas
    I'm learning WPF and would like to have a collection similar to a LinkedList, to where I can add and remove strings. And I want to have a ListView that listen to that collection with databinding. How can I do bind a simple list collection to a ListView in XAML? My idea (not working) is something like this: <Window ...> <Window.Resources> <LinkedList x:Key="myList"></LinkedList> <Window.Resources> <Grid> <ListView Height="100" HorizontalAlignment="Left" Margin="88,134,0,0" Name="listView1" VerticalAlignment="Top" Width="120" ItemsSource="{Binding Source={StaticResource myList}}"/> </Grid> </Window>

  • Open source jigsaw piece generator

    - by codecowboy
    Hi, Does anyone know of a C-based open source class / framework which can generate a random jigsaw puzzle from an image or generate a random puzzle template which could then be applied to an image? The puzzle pieces must have male and female notches/holes. There should be more than one template so that the puzzle does not become too easy. The target system is iOS / Mac. If not, how would you approach this problem? The puzzle pieces should be as close to a real jigsaw piece shape as possible and the system must be dynamic so that the user can use their own photos or download photos. thanks!

    - by Roy

  • Creating a db driven primary navigation in django?

    - by Fedor
    I find that it's pretty common most people hardcode the navigation into their templates, but I'm dealing with a pretty dynamic news site which might be better off if the primary nav was db driven. So I was thinking of having a Navigation model where each row would be a link. link_id INT primary key link_name varchar(255) url varchar(255) order INT active boolean If anyone's done something similar in the past, would you say this sort of schema is good enough? I also wanted for there to be an optional dropdown in the admin near the url field so that a user could choose a Category model's slug since category links would be common, but I'm not quite sure how that would be possible.

  • Different ways to specify libraries to gcc/g++

    - by abigagli
    I'd be curious to understand if there's any substantial difference in specifying libraries (both shared and static) to gcc/g++ in the two following ways (CC can be g++ or gcc) CC -o output_executable /path/to/my/libstatic.a /path/to/my/libshared.so source1.cpp source2.cpp ... sourceN.cpp vs CC -o output_executable -L/path/to/my/libs -lstatic -lshared source1.cpp source2.cpp ... sourceN.cpp I can only see a major difference being that passing directly the fully-specified library name would make for a greater control in choosing static or dynamic versions, but I suspect there's something else going on that can have side effects on how the executable is built or will behave at runtime, am I right? Andrea.

  • Dreamweaver recordset filter - Display all records as default

    - by Drew
    I am trying to create a simple search form to filter the results in the dynamic table. The search form is on the same pages as the results and posts to itself. I get the search string from the post variable. It is working, but I can't figure out how to set the default value to display all results. Dreamweaver automatically sets the default value to -1, and therefore no results are displayed on the initial load. How do I change this to display ALL records as default and the filter only if there is search string defined.

  • Multiple sections on landing page only

    - by RDRAO
    Hi every one, I am very much new to Drupal but am loving it to start with. I got struck at a point with respect to theaming. I have a region called 'footer-teaser' just above footer. Its width is 800px. its been split into 3 equal size columns. Each column has the following. Image of size 120x120 Some teaser text Link to 'read more' The design requirement is all the above should be editable by the admin from the admin interface. If its static i would have hardcoded this but since the requirement is dynamic, i am not aware of how to achieve this. I have customised page.tpl for other sections of the page except this. I am sure someone else would have faced this issue before and was wondering if anyone can direct me in the right direction? Even better if an example is provided. Cheers RD

  • Rails fixtures seem to be adding extra unexpected data

    - by Mason Jones
    Hello, all. I've got a dynamic fixture CSV file that's generating predictable data for a table in order for my unit tests to do their thing. It's working as expected and filling the table with the data, but when I check the table after the tests run, I'm seeing a number of additional rows of "blank" data (all zeros, etc). Those aren't being created by the fixture, and the unit tests are read-only, just doing selects, so I can't blame the code. There doesn't seem to be any logging done during the fixtures setup, so I can't see when the "blank" data is being inserted. Anyone ever run across this before, or have any ideas of how to log or otherwise see what the fixture setup is doing in order to trace down the source of the blank data?

  • how to get dynamically created elements width and apply style to that?

    - by 3gwebtrain
    Hi, I am creating an li element dynamically like this: $(data).find('slide').each(function(numSlide){ var slideLink = $(this).attr('link'); var slideimage = $(this).children('slideimage').text(); var slidedesc = $(this).children('slidedesc').text(); $('.slider ul').append('<li><a href="'+slideLink+'"><img src="'+root+"images/top-slider-image/"+slideimage+'" alt="welcome to Burger Davis Blog" /></a><div class="note">'+slidedesc+'</div></li>'); }) But I'd like to calculate the width of the li, and I need to apply some style to it -- how can I do that? If I add styles via the css method, it does not work for dynamically created elements... Please help me to get dynamic elements' width and how to apply styles into that? I know we can use the live function, but I can't get even by that..

  • There was no endpoint listening at http://localhost:49481/Marketing.svc that could accept the message

    - by duckmike
    I have a Marketing service running locally through port 49481 and through IIS on port 65000. Either way when I try to debug into that service, I get an error message - {"There was no endpoint listening at http:/localhost:49481/Marketing.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details."} My inner exception is - {"The remote server returned an error: (404) Not Found."} I can open that service address, http:/localhost:49481/Marketing.svc, through a browser and I get a message that it's running ok. My config file is set up like - <endpoint address="http://localhost:49481/Marketing.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IMarketing" contract="SunriseMarketing.IMarketing" name="BasicHttpBinding_IMarketing" /> What am I missing?

  • Know if a Visual Studio Website project is recompiling itself in the background?

    - by jdk
    A number of team members update a central ASP.NET dev site (Website project, not a Web application type). Some kinds of changes cause a recompile/rebuild in it. The large website takes a while to recompile and we've noticed it will still seemingly serve out dynamic pages before everything is internally updated. During the site's "gestation" period, our mileage varies while hitting it. Sometimes we get a correct page, sometimes an compilation error page that will eventually be served up without a compilation error, and at other times an unexpected hybrid. Is it possible to query an ASP.NET website application to see if it's currently compiling or rebuilding itself? If so I would write a status page that the team could reference when they're getting weird behaviour, so they would know to wait. Update: Our team often edit files manually on the dev server. For production we'd make pre-compiled pushes. The dev environment is a little more malleable and ever-changing so I'm looking for a solution to reducing the "confusion" there.

  • Creating a templated silverlight control that has a story board.

    - by Mrt
    I'm trying to create a templated silverlight control that has a simple animation (swap a few color properties). An example would be a control that is similar to the 'questions' menu item in stackoverflow. So the consumer of the control can specify the background color and the background color for the mouseover event. I've run into the issue that I can't use template binding for a storyboard animation (http://stackoverflow.com/questions/1336689/is-it-possible-to-use-templatebinding-in-a-storyboard-in-silverlight). Whats the best work around to this ? Cheers, MrT

  • How to bind a List<DateTime> to a DataGridView/ListBox .NET C#

    - by nat
    Hi there I have a List that I want to bind to a DataGridView in a windows forms app. however, I cannot for the life of me find the DataPropertyName I need to show what I want. I have had similar problems with binding this list to a listbox. what i really want is to show .ToString("dddd, dd MMMM yyyy HH:mm"), or certainly more than the standard 'date' part of the datetime - do i need to add a property of my own? public partial class DateTime{ public string myFormat{ get{return this.ToString("dddd dd MMM yyyy HH:mm");} } } or some such? thanks nat

  • jQuery > reset popup window 's x and y relative to icon that launched the window

    - by Scott B
    I have a jQuery jPicker colorpicker that is bound to an input text field and opens onclick of a small picker.gif icon. The problem I'm having is that (1) The colorpicker that opens does not appear to be positioned according to the x/y position of the picker.gif (it opens far away from the click point) and (2) The colorpicker does not seem to be aware of the viewport's scroll position (the top of the colorpicker is partially hidden at the top of the window). I'd like to use jQuery to reposition the colorpalette (1) Based on the x/y position of the input that its bound to and (2) reset it's top position based on the viewport's visible Y position. Here is the script where I am creating a new jPicker and binding it to my input text fields for header and sidebar... $('#myHeaderColor').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } ); $('#mySidebarColor').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } );

  • Wordpress page linking

    - by danixd
    I am trying to implement WordPress into quite a large site with a complex page structure and struggling to get normal pages to work (not created through the admin) The pages are created, but when I link to them, nothing happens... The desired url - www.website.com/dir1/dir2/dir3/page.php The actual url- www.website.com/wp-content/themes/themename/dir1/dir2/dir3/page.php The problem with linking to the latter is that it breaks the WordPress functions I don't want to have to give every page a template, then add it through the admin, it is too much work. I only need 2 pages to contain dynamic content. Am I being silly? I am really confused.

  • Making GridView Respond to 2 Drop Down Lists

    - by raziiq
    Hi there. I have got 2 Drop Down Lists on my Form and 1 GridView. I want GridView to display the data according to selection from the Drop Down Lists. For Example, One Drop Down List contains Names and other contains Dates. Both the Drop Down Lists can post back. So if i select a name from 1st Drop Down list, the Grid View should show all the results according to that Name. Similarly if i select the Date from the other Drop Down List , the Grid View should show the results according to the dates. But i cant figure out as how to bind Grid View to respond to 2 Drop Down List. BTW i am binding both the Drop Down Lists and the Grid View to the DataSource Objects, which is getting data from the database. Any Suggestions??

  • Silverlight 4 Multithread

    - by DavyMac23
    I'm trying to update my Silverlight 4 UI approx every 1/2 second with new data. I've hooked into a WCF service using net.tcp binding and issuing callbacks from the server. To make sure I get the data from the service as quickly as possible I've started up my proxy on a backround worker inside of my Silverlight App. My question is, how do I get the results from the callback and update the ObservableCollection that is bound to a datagird? I've tried a number of different ways and keep getting the dreaded cross-thread error.

  • Spring+JSP url building best practices

    - by dotsid
    I wonder if there are any good practices for addressing Spring controllers in JSP. Suppose I have controller: @Controller class FooController { // Don't bother about semantic of this query right now @RequestMapping("/search/{applicationId}") public String handleSearch(@PathVariable String applicationId) { [...] } } Of course in JSP I can write: <c:url value="/search/${application.id}" /> But it's very hard to change url then. If you familiar with Rails/Grails then you now how this problem resolved: redirect_to(:controller => 'foo', :action = 'search') But in Spring there is so much UrlMappers. Each UrlMapper have own semantic and binding scheme. Rails alike scheme simply doesn't work (unless you implement it yourself). And my question is: are there any more convenient ways to address controller from JSP in Spring?

  • nginx + ssi + remote uri access does not work

    - by stunti
    I have a setup where my nginx is in front with apache+PHP behind. My PHP application cache some page in memcache which are accessed by nginx directly except some dynamic part which are build using SSI in Nginx. The first problem I had was nginx didnt try to use memcache for ssi URI. <!--# include virtual="/myuser" --> So I figured that if I force it to use a full URL, it would do it. <!--# include virtual="http://www.example.com/myuser" --> But in logs file (both nginx and apache) I can see that a slash has been added at the beginning of the url http ssi filter "/http://www.example.com/myuser" In the source code of the SSI module I see a PREFIX that seems to be added, but I can really tell if I can disable it. Anybody got this issue? Nginx version : 0.7.62 on Ubuntu Karmic 64bits Thanks a lot

  • x86 Assembly - printf doesn't print without "\n"

    - by Bitani
    So I'm confused. I'm going through the book "Programming from the Ground Up" and am working with using libraries. printf is working just fine so long as I include a "\n" in the string, but without it it will print absolutely nothing. Any idea why this happens? Code: .section .data my_str: .ascii "Jimmy Joe is %d years old!\n\0" my_num: .long 76 .section .text .globl _start _start: pushl my_num pushl $my_str call printf movl $1, %eax movl $0, %ebx int $0x80 Also, when I use -m elf_i386 for 32-bit mode and -dynamic-linker /lib/ld-linux.so.2 -lc to link, I get the warning ld: skipping incompatible /usr/lib64/libc.so when searching for -lc If that makes any difference, or if anybody has any suggestions as to how to have it load the 32-bit library directly. Thanks!

  • Using Gridview in aspx.vb (code-behind)

    - by Tauron Xavenberg
    I need to create a gridview based on 2 different datasources: main and sub-cathegory. And I need to list them like below: Productinfo sub-product 1 sub-product 2 Productinfo sub-product 1 sub-product 2 sub-product 3 sub-product 4 Etc... the thing is that both the "productinfo" and the "sub-product" are dynamic as the number of both can vary, so I would have to create a gridview within a gridview, plus the necessary filters too. For this reason I thought it was best to do it all in code-behind, but I can't understand how to use the gridview-class in codebehind and bind it so that it actually shows something in the main aspx page. Basically what I'm asking for is a simple example of how, when you have nothing but <asp:GridView/> in the aspx -page, can you add components to it and show it, from code-behind (vb)? Thanks.

  • Accented character regex

    - by user314573
    I'm trying to create a regex that will look for french words whether a user specifies the accented characters or not. So if the the user has searched for "déclaré" but types in declare instead I would like to be able to match the text still. I'm having difficulty making this more dynamic so that it can be matched on any french word... Closest example from another user from a different post was: d[eèéê]cl[aàáâ]r[eèéê] Is it even possible to write a regex for something like this? Any advice would be much appreciated.
