  • Bind Grid.Row / Grid.Column inside a DataTemplate

    - by Thorsten79
    Hope this is not a dupe. I would like to be able to do the following in XAML: <DataTemplate DataType="{x:Type NewGACCTestApp:ButtonVM}"> <Button Grid.Column="{Binding GridColumn}" Grid.Row="{Binding GridRow}" Content="{Binding Path=Info}" /> </DataTemplate> The Content binding works fine but Grid.Column and Grid.Row simply don't exist in the produced object. Not even when I set them to some value without binding (like in Grid.Column="1"). I've snooped the application and saw that inside my grid nobody ever sets Grid.Column and Grid.Row. Any ideas?

  • Creating a blocked user intercepter in Grails

    - by UltraVi01
    I am working on a social site where users can block other users. Throughout the site --dozens of places, user information is displayed. For example, user comments, reply forms, online user list.. etc etc.. The problem is that given the high number of places user info is displayed, it's becoming very difficult to check each time if that user is blocked. For example: <g:each var="comment" in="${comments}"> <g:if test="!${loggedInUser.blockedUsers.find { it == comment.user}"> show comment </g:if> </g:each> Does Grails provide any functionality that would facilitate creating some kind of filter or intercepter where I could simply exclude blocked users when iterating lists, etc? If not, what would you suggest I do?

  • Django: Why Doesn't the Current URL Match any Patterns in urls.py

    - by austin_sherron
    I've found a few questions here related to my issue, but I haven't found anything that has helped me resolve my issue. I'm using Python 2.7.5 and Django 1.8.dev20140627143448. I have a view that's interacting with my database to delete objects, and it takes two arguments in addition to a request: def delete_data_item(request, dataclass_id, dataitem_id): form = AddDataItemForm(request.POST) data_set = get_object_or_404(DataClass, pk=dataclass_id) context = {'data_set': data_set, 'form': form} data_item = get_object_or_404(DataItem, pk=dataitem_id) data_item.delete() data_set.save() return HttpResponseRedirect(reverse('detail', args=(dataclass_id,))) The URL in myapp.urls.py looks something like this: url(r'^(?P<dataclass_id>[0-9]+)/(?P<dataitem_id>[0-9]+)/delete_data_item/$', views.delete_data_item, name='delete_data_item') and the portion of my template relevant to the view is: <a href="{% url 'delete_data_item' data_set.id data_item.id %}">DELETE</a> Whenever I click on the DELETE link, django tells me that the request URL: http://127.0.0.1:8000/myapp/5/%7B%%20url%20'delete_data_item'%20data_set.id%20data_item.id%20%%7D doesn't match any of my URL patterns. What am I missing? The URL on which the DELETE links exist is myapp/(<dataclass_id>[0-9]+)/

  • How to select rows from data.frame with 2 conditions

    - by Peter Smit
    I have an aggregated table: > aggdata[1:4,] Group.1 Group.2 x 1 4 0.05 0.9214660 2 6 0.05 0.9315789 3 8 0.05 0.9526316 4 10 0.05 0.9684211 How can I select the x value when I have values for Group.1 and Group.2? I tried: aggdata[aggdata[,"Group.1"]==l && aggdata[,"Group.2"]==lamda,"x"] but that replies all x's. More info: I want to use this like this: table = data.frame(); for(l in unique(aggdata[,"Group.1"])) { for(lambda in unique(aggdata[,"Group.2"])) { table[l,lambda] = aggdata[aggdata[,"Group.1"]==l & aggdata[,"Group.2"]==lambda,"x"] } } Any suggestions that are even easier and giving this result I appreciate!

  • ASP.NET - remote screenshot

    - by ufoq
    Hi All, I made a very very simple small app to take screenshot of the desktop and send to network share. About 10 PC's would have this app installed. My idea is, that there will be one dashboard in ASP.NET, which simply shows those screenshots on the webpage. So far, easy stuff. But, because I don't want to clog the network and send the screenshot every 1 minute, I would like to launch the .exe on the remote PC's by demand of ASP.NET user. Unfortunately I haven't found any information (and I'm a complete ASP.NET n00b), how to launch remote executable IN the context of the remote PC (so I won't see screenshots of ASP server :) ) If there is no such possibility, please advise about other way to solve this.

  • problem-configure-jboss-to-work-with-jndi(3)

    - by Spiderman
    Sorry for opening new thread every time for the same problem. It's just that I'd like to refine my question during my investigation and it's hard to do it in stackoverflow structure on the same question (maybe on purpose). Anyway, in continuation to this thread http://stackoverflow.com/questions/2843218/problem-configure-jboss-to-work-with-jndi2 I discovered that when running an application that is deployed on my JBoss 4.2.3.GA, when I perform: Context initialContext = new InitialContext(); Object dataSource = initialContext.lookup("java:/DefaultDS"); I get null as a return value even though DefaultDS is the default datasource that comes with Jboss installation. and generally, how come initialContext return null value? if the datasource is not found it should throw NamingException and in other case it should return real object. What can I do with null? isn't it a bad error handling of javax.naming.InitialContext ???

  • Exception wrapping and HTML pages

    - by dotnetdev
    Hi, We have a sharepoint 2007 project at work. The exception handling policy is to log to the Sharepoint logs. In this case, would the best approach be to call that method and then rethrow the exception higher up? Except if I rethrow it to be caught higher up, there is no other exception handling code so what would happen in this case? Also, if you are going to display a more friendly error to the user (which uses information in the exception object), then this would be a good use of exception wrapping. Would it be a good idea to make a custom aspx page and add these to customerrors, so that on init (not sure of the exact event), I can display exception info in the passed parameter on the page. However, a static html page can't do this so I don't see the point in wrapping exceptions (unless there is a page or alert which uses the exception object). So if a project uses html pages for errors, is there a point in wrapping exceptions? Thanks

  • php, extract data from a non-standard xml document

    - by Michael
    I have some kind xml content I need to extract the information and store it into database <xml file="136000000-136100000"> <Id>136000000</Id> <Name>Sem Serxy</Na me> <Email>[email protected]</Email> <DateRegistration>10/13/2010 1:49:30 AM</DateRegistration> </xml> <xml file="136000000-136100000"> <Id>136000001</Id> <Name>God Deckor</Name> <Email>[email protected]</Email> If I try simple xml load is not working as the document doesn't seem to be valid xml. I can use regex to extract the info with preg_match_all but I feel this is not the right way as the data is already well structured. Any other method ?

  • What elegant method callback design should be used ?

    - by ereOn
    Hi, I'm surprised this question wasn't asked before on SO (well, at least I couldn't find it). Have you ever designed a method-callback pattern (something like a "pointer" to a class method) in C++ and, if so, how did you do it ? I know a method is just a regular function with some hidden this parameter to serve as a context and I have a pretty simple design in mind. However, since things are often more complex than they seem to, I wonder how our C++ gurus would implement this, preferably in an elegant and standard way. All suggestions are welcome !

  • Why isn't this simple test class's method inherited in Ruby?

    - by Kevin Bannister
    Consider this very simple logging class: class MockLog def self.log_stub_method(*args) args.each do |a| define_method "#{a}" do |msg| t = Time.now.strftime("%Y-%m-%d %H:%M:%S") $stderr.puts "[#{a.upcase}] \u00bb [#{t}] #{msg}" end end end log_stub_method :fatal, :error, :warn, :info, :debug end Let's add logging to all our classes: class Module def has_logging() class_eval { @log = MockLog.new def log self.class.instance_variable_get :@log end } end end Now, why doesn't this work? class Foo has_logging end Foo.new.log.nil? # => false, as expected class Bar < Foo end Bar.new.log.nil? # => true?! Why wasn't the `log` method inherited?

  • I'm having a hard time wrapping my head around handling the Activity Lifecycle...

    - by kefs
    So it seems i've created a fatal flaw and coded an app before understanding/handling rotation/lifecycle events.. Currently, all of my code is in onCreate of each activity. I've read a lot of lifecycle tutorials online, including the official dev guide info, but i'm still having an almost unbelievably hard time trying to wrap my head around the rotation/lifecycle events/methods and when to use them correctly. For example, my app currently has an activity that opens the db, inserts a record, then closes the db.. if i rotate my screen on this activity, the data is re-entered into the db. Using the available lifecycle events (onPause(), onResume(), etc..), how would I prevent this db call from happening again? Would I have to pass a variable through the state saying that the db call has been done, and not to do it again? Thanks in advance..

  • Maven install-file won't generate pom.xml

    - by anotherCoder
    I've installed some third party jars to my repository using the following command: mvn install:install-file -Dfile=/home/anotherCoder/Downloads/nifty-1.0.jar -DgroupId=nifty-gui -DartifactId=nifty-gui -Dversion=1.0 -Dpackaging=jar However, once I do mvn compile, maven complains that there is no pom file in the repository and attempts to download it, but can't cause it is not published at any remote repository. Here is the exact message from maven: Downloading: http://repo1.maven.org/maven2/nifty-gui/nifty-gui/1.0/nifty-gui-1.0.pom [INFO] Unable to find resource 'nifty-gui:nifty-gui:pom:1.0' in repository central (http://repo1.maven.org/maven2) So how do I get maven to generate a pom file for that jar and put it in my local repository?

  • How do you compare music data

    - by Chris
    i want to write an app to rename sort and organize my music library (mp3's, wav's, flac's). I wanted to take a portion of the song, say the first minutes, and compare that to a database and then retrieve the song name and tag information. I have heard that you can do this with last.fm but a look through their api info didn't help. My question is, what is this called so i can google it better? nothing i am trying is helping much. This would be similar to the shazam android app. My prefered language would be java, so i can run it on a few operating systems easier, but that might be subject to change depending on how i can do it. Thanks

  • PHP Magento Screen Scraping

    - by Grant unwin
    I am trying to scrape a suppliers magento site in an effort to save some time because of there being around 2000 products I need to gather info for. I'm totally OK with writing a screen scraper for pretty much anything but i've encountered a major problem. Im using get_file_contentsto gather the html of the product page. The problem is: You need to be logged in, to view the product page. Its a standard magento login, so how can I get round this in my screen scraper? I don't require a full script, just advice on a method. Thanks

  • Can I compile and execute C# expression without saving the assembly to disk?

    - by Sasha
    I can compile, get an instance and invoke a method of any C# type programmaticaly. There lots of info on that, including the StackOverflow (http://stackoverflow.com/questions/53844/how-can-i-evaluate-a-c-expression-dynamically). My problem is that I'm in the web environment and cannot save anything to /bin directory. I can compile "in-memory" as the above mentioned link suggests but then I won't be able to "unload" my custom assembly from the current AppDomain. After a while that will become a huge memory problem. Is it possible to open a new AppDomain, compile new assembly "in-memory", evaluate some expression or access some member of that assembly inside of that new AppDomain and kill that AppDomain safely when done, all that without saving anything to a hard drive? Thanks in advance for any links, suggestions, etc.

  • Reading TCP Sequence Number Before Sending a Packet

    - by Sadeq Dousti
    I'm writing a C/C++ client-server program under Linux. Assume a message m is to be sent from the client to the server. Is it possible for the client to read the TCP sequence number of the packet which will carry m, before sending m? In fact, I'd like to append this sequence number to m, and send the resulting packet. (Well, things are more complicated, but let's keep it that simple. In fact, I'd like to apply authentication info to this sequence number, and then append it to m.) Moreover, is it possible for the server to read the TCP sequence number of the packet carrying m?

  • Grails Services / Transactions / RuntimeException / Testing

    - by Rob
    I'm testing come code in a service with transactional set to true , which talks to a customer supplied web service the main part of which looks like class BarcodeService { .. /// some stuff ... try{ cancelBarCodeResponse = cancelBarCode(cancelBarcodeRequest) } catch(myCommsException e) { throw new RuntimeException(e) } ... where myCommsException extends Exception .. I have a test which looks like // As no connection from my machine, it should fail .. shouldFailWithCause(RuntimeException){ barcodeServices.cancelBarcodeDetails() } The test fails cause it's catching a myCommsException rather than the RuntimeException i thought i'd converted it to .. Anyone care to point out what i'm doing wrong ? Also will the fact that it's not a RuntimeException mean any transaction related info done before my try/catch actually be written out rather than thrown away ?? Thanks

  • how rspec creates database between specs

    - by timpone
    This is a bit of a naive / simple question. I'm having a hard time finding this info online. Basically, does rspec run rake db:test:prepare between every rspec group? Or is it between every example or model? Or does the schema get loaded once and then truncated between each. I need to add a rake task directly after this call to create a view since they are not supported in schema.rb. Either a link or explanation would be greatly appreciated so that I know where to insert my rake task to create a view. Or whether there is a callback like rake db:test:after_prepare thx

  • Character encoding issues in MySQL

    In my database we have fields where the data is not readable. I now know why it happened but I don't know how to fix it. I found a way to get the info back from the database: SELECT id, name FROM projects WHERE LENGTH(name) != CHAR_LENGTH(name); One of the rows returned shows: id | name ------------------------- 1008 | Cajón el Diablo This should be: id | name ------------------------- 1008 | Cajón el Diablo Can somebody help me figure out how to fix this problem? How can I convert this using SQL? Is SQL not good? If not, how about Python?

  • PHP MySQL Syntax Error 'You have an error in your SQL syntax'

    I cannot figure out the issue with my code here. I am trying to take info from the table, then subtract 1 second from Current_Time which looks like '2:00'. The problem is, I get: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Current_Time) VALUES('22')' at line 1" I don't even understand where it gets 22 from. Thanks, I really appreciate it. if (isset($_GET['id']) && isset($_GET['time'])) { mysql_select_db("aleckaza_pennyauction", $connection); $query = "SELECT Current_Time FROM Live_Auctions WHERE ID='1'"; $results = mysql_query($query) or die(mysql_error()); while ($row = mysql_fetch_array($results)) { $newTime = $row['Current_Time'] - 1; $query = "INSERT INTO Live_Auctions(Current_Time) VALUES('".$newTime."')"; $results = mysql_query($query) or die(mysql_error()); } }
