  • How to access a plugin model from a regular controller in PHP Cake 1.1

    - by Duncan
    Hopefully a simple question: I've a plugin which uses a set of tables (kb_items, kb_item_tags, etc). and I'd like to be able to access these models from another controller (say, my Pages controller), thus: class PagesController extends AppController{ function knowledgebase(){ $items = $this->KbItem->findAll(...); } } I am admittedly breaking the rules a little (by not placing this controller inside the knowledge base plugin), but this in this case its a custom page that doesn't need to be part of the knowledge base plugin code base. Please let me know if you need more details. Thanks in advance for any help!

  • Overcoming C limitations for large projects

    - by Francisco Garcia
    One aspect where C shows its age is the encapsulation of code. Many modern languages has classes, namespaces, packages... a much more convenient to organize code than just a simple "include". Since C is still the main language for many huge projects. How do you to overcome its limitations? I suppose that one main factor should be lots of discipline. I would like to know what you do to handle large quantity of C code, which authors or books you can recommend.

  • Using Excel To Read Access Without MS Access On Computer

    - by Tom Clark
    I have written code that joins two table in access, using criteria supplied from drop down lists in excel and then returns the data to a specific location on the spreadsheet (titles already on the sheet). This works fine on my box and others with MS Access on the machine, but the purpose of writing this was to give people (associates) that dont have the MS Access on their machines (which is most of them) to be able to do simple queries to the database. When we try to run this on a machine without MS Access, we are getting the error message "Compile Error: Cant find project or library." Since this works fine on any machine so far that has Access, but not the others I am wondering if this is not possible without the actual Access software. Any help or insight would be appreciated. Tom

  • Binding to 'To' In Storyboard

    - by Peanut
    I'll try to make this as simple as I can. I want to do this: <Storyboard x:Name="MoveToLocation"> <DoubleAnimation Duration="0:0:0.5" To="{Binding X}" Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateX)" Storyboard.TargetName="grid" d:IsOptimized="True"/> </Storyboard> As you may have noticed the Binding on 'To' Property does not work. It seems to only accept static values. How does one do this animation with MVVM? I cant just put in static data, cause it's going to change. Thanks.

  • Android: duplicate items in ListVew. Maybe getView() called too many times?

    - by gonzobrains
    Hi, I am trying to create a simple program which displays a "shopping cart" list of items, along with a few buttons below it to manage the cart. The biggest problem is that items are getting duplicate entries in the list view. That is, for every item I want to enter I see it appear two times in the list view. What's the problem? Also, the scrollable area of my cart is not big enough. How do I set it so that it is bigger but I can still see my buttons? Perhaps I should put the buttons above the cart? Here is my shopping cart's layout XML: Here is the layout for individual row items: <LinearLayout android:orientation="vertical" android:layout_width="0dip" android:layout_weight="1" android:layout_height="fill_parent"> <TextView android:id="@+id/BookTitle" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:singleLine="true" android:gravity="center_vertical" / <TextView android:id="@+id/BookPrice" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:singleLine="true" android:ellipsize="marquee" / Thanks, gb

  • WPF - Handling events from user control in View Model

    - by Vitaly
    I’m building a WPF application using MVVM pattern (both are new technologies for me). I use user controls for simple bits of reusable functionality that doesn’t contain business logic, and MVVM pattern to build application logic. Suppose a view contains my user control that fires events, and I want to add an event handler to that event. That event handler should be in the view model of the view, because it contains business logic. The question is – view and the view model are connected only by binding; how do I connect an event handler using binding? Is it even possible (I suspect not)? If not – how should I handle events from a control in the view model? Maybe I should use commands or INotifyPropertyChanged?

  • Concurency issues with scheduling app

    - by Sazug
    Our application needs a simple scheduling mechanism - we can schedule only one visit per room for the same time interval (but one visit can be using one or more rooms). Using SQL Server 2005, sample procedure could look like this: CREATE PROCEDURE CreateVisit @start datetime, @end datetime, @roomID int AS BEGIN DECLARE @isFreeRoom INT BEGIN TRANSACTION SELECT @isFreeRoom = COUNT(*) FROM visits V INNER JOIN visits_rooms VR on VR.VisitID = V.ID WHERE @start = start AND @end = [end] AND VR.RoomID = @roomID IF (@isFreeRoom = 0) BEGIN INSERT INTO visits (start, [end]) VALUES (@start, @end) INSERT INTO visits_rooms (visitID, roomID) VALUES (SCOPE_IDENTITY(), @roomID) END COMMIT TRANSACTION END In order to not have the same room scheduled for two visits at the same time, how should we handle this problem in procedure? Should we use SERIALIZABLE transaction isolation level or maybe use table hints (locks)? Which one is better?

  • getResourceAsStream not loading resource in webapp

    - by mangst
    I have a web application that uses a library which resides in TOMCAT_HOME/common/lib. This library looks for a properties file at the root of the classpath (in a class called ApplicationConfig): ApplicationConfig.class.getResourceAsStream("/hv-application.properties"); My Tomcat web application contains this properties file. It is in WEB-INF/classes, which is the root of the classpath right? However, at runtime, when it tries to load the properties file, it throws an exception because it can't find it (getResourceAsStream returns null). Everything works fine if my application is a simple, standalone Java application. Does Tomcat cause the getResourceAsStream method to act differently? I know there's a lot of similar questions out there, but none of them have helped unfortunately. Thanks.

  • Load a UIView from a NIB

    - by Winder
    I have been using UIViewControllers and initWithNibName with much success, basically using them as a convenient way to design the view with Interface Builder. Unfortunately I have built a hierarchy of views before noticing this line in the UIViewController documentation: Note: You should not use view controllers to manage views that fill only a part of their window My question is this: Having a very simple NIB that only has a UIView in addition to the default First Responder and Owning Object, what is the simplest way to load the UIView into my code? I have not been able to get loadNibNamed:owner:options: to work at this point, but suspect the answer will involve it somehow.

  • Twisted - how to create multi protocol process and send the data between the protocols

    - by SpankMe
    Hey, Im trying to write a program that would be listening for data (simple text messages) on some port (say tcp 6666) and then pass them to one or more different protocols - irc, xmpp and so on. I've tried many approaches and digged the Internet, but I cant find easy and working solution for such task. The code I am currently fighting with is here: http://pastebin.com/ri7caXih I would like to know how to from object like: ircf = ircFactory('asdfasdf', '#asdf666') get access to self protocol methods, because this: self.protocol.dupa1(msg) returns error about self not being passed to active protocol object. Or maybe there is other, better, easier and more kosher way to create single reactor with multiple protocols and have actions triggeres when a message arrives on any of them, and then pass that message to other protocols for handling/processing/sending? Any help will be highly appreciated!

  • AJAX with Ruby on Rails?

    - by Zachary
    This is probably a really dumb question with a simple answer but... I am working on a project where I need to use AJAX to send/receive information. I am using Ruby on Rails (which I am pretty new to), but rather than using the helper methods or the built in functionality in the 'defaults' Javascript file, I need to do this manually in my own Javascript. I believe that ultimately I will want to send a request with a JSON object, then have the controller return another JSON object containing the requested information. The problem is that I cannot seem to find the syntax for sending something to a specific controller method, with parameters, directly from Javascript - everything I Google ends up being tutorials for using the Rails AJAX helper methods.

  • Randomized experiments in R

    - by gd047
    Here is a simple randomized experiment. In the following code I calculate the p-value under the null hypothesis that two different fertilizers applied to tomato plants have no effect in plants yields. The first random sample (x) comes from plants where a standard fertilizer has been used, while an "improved" one has been used in the plants where the second sample (y) comes from. x <- c(11.4,25.3,29.9,16.5,21.1) y <- c(23.7,26.6,28.5,14.2,17.9,24.3) total <- c(x,y) first <- combn(total,length(x)) second <- apply(first,2,function(x) total[!total %in% x]) dif.treat <- apply(second,2,mean) - apply(first,2,mean) # the first element of dif.treat is the one that I'm interested in (p.value <- length(dif.treat[dif.treat >= dif.treat[1]]) / length(dif.treat)) Do you know of any R function that performs tests like this one?

  • Getting Raw XML From SOAPMessage in Java

    - by Daniel Lew
    I've set up a SOAP WebServiceProvider in JAX-WS, but I'm having trouble figuring out how to get the raw XML from a SOAPMessage (or any Node) object. Here's a sample of the code I've got right now, and where I'm trying to grab the XML: @WebServiceProvider(wsdlLocation="SoapService.wsdl") @ServiceMode(value=Service.Mode.MESSAGE) public class SoapProvider implements Provider<SOAPMessage> { public SOAPMessage invoke(SOAPMessage msg) { // How do I get the raw XML here? } } Is there a simple way to get the XML of the original request? If there's a way to get the raw XML by setting up a different type of Provider (such as Source), I'd be willing to do that, too.

  • Safe executing shell scripts; escaping vars before execution.

    - by Kirzilla
    Hello, Let's imagine that we have a simple php script that should get ssh_host, ssh_username, ssh_port from $_GET array and try to connect using this parameters to SSH. $port = escapeshellcmd($_GET['ssh_port']); $host = escapeshellcmd($_GET['ssh_host']); $username = escapeshellcmd($_GET['ssh_username']); $answer = shell_exec("ssh -p " . $port . " " . $user . "@" . $host); Is escapeshellcmd() enough or I need something more tricky? Or maybe I should use escapeshellarg() in this example? Thank you.

  • I have a question about URI templates in WCF Services

    - by Debby
    I have a web service with following operation contract and my service is hosted at http://localhost:9002/Service.svc/ [OperationContract] [WebGet(UriTemplate = "/Files/{Filepath}")] Stream DownloadFile(string Filepath); This web service would let users download file, if the proper filepath is provided (assuming, I somehow find out that proper filepath). Now, I can access this service from a browser by typing, http://localhost:9002/Service.svc/Files/(Filepath} If {filepath} is some simple string, its not a problem, but I want to send the location of the file. Lets us say users want to download file C:\Test.mp3 on the server. But how can I pass C:\Test.mp3 as {Filepath}? I get an error when I type http://localhost:9002/Service.svc/Files/C:\Test.mp3 in the browser. I am new to web services and find that this community is the quickest way to get answers to my questions.

  • Choosing Merge Direction

    - by tbreffni
    Consider a simple source-control layout, with a trunk representing a future release in development and a single branch representing a release currently in production. When a bug is discovered that needs fixed in both branches, should the change be made first to the trunk then merged down to the branch, or made first to the branch then merged up to the trunk? Typically I've made the fix first in the trunk then merged downwards, however there is an increased risk this way that future new features get merged down accidentally. What has worked best in your experience?

  • Project design / FS layout for large django projects

    - by rcreswick
    What is the best way to layout a large django project? The tutuorials provide simple instructions for setting up apps, models, and views, but there is less information about how apps and projects should be broken down, how much sharing is allowable/necessary between apps in a typical project (obviously that is largely dependent on the project) and how/where general templates should be kept. Does anyone have examples, suggestions, and explanations as to why a certain project layout is better than another? I am particularly interested in the incorporation of large numbers of unit tests (2-5x the size of the actual code base) and string externalization / templates.

  • What's a reasonable number of rows and tables to be able to join in MySQL?

    - by Philip Brocoum
    I have one table that maps locations to postal codes. For example, New York State has about 2000 postal codes. I have another table that maps mail to the postal codes it was sent to, but this table has about 5 million rows. I want to find all the mail that was sent to New York State, which seems simple enough, but the query is unbelievably slow. I haven't been able to even wait long enough for it to finish. Is the problem that there are 5 million rows? I can't help but think that 5 million shouldn't be such a large number for a computer these days... Oh, and everything is indexed. Is SQL just not designed to handle such large joins?

  • Silverlight: Use reflection to get the BindingExpression (and value) for controls having a ContentPr

    - by sfx
    Hello, I need to use reflection to get the binding value in a control that is a DataGridTemplateColumn (e.g HyperLinkButton). Does anyone know how I might do this? It seems simple enough to do this with a TextBlock because it has a “TextProperty” dependency property, but I can’t seem to get a binding expression from a control that does not have an immediate “TextProperty”. Here is the code I’m using to acquire the binding expression for a TextBlock: FrameworkElement fe = (FrameworkElement)dependencyObj; FieldInfo fi = fe.GetType().GetField("TextProperty"); BindingExpression bindingExpression = fe.GetBindingExpression((DependencyProperty)fi.GetValue(null)) However, the following code never works for a dependency object that is a HyperLinkButton: FieldInfo fi = fe.GetType().GetField("ContentProperty"); Does anyone know how I might be able to get the BindingExpression (and binding value) for the content of a HyperLinkButton? Cheers, sfx

  • JavaScript - Textarea Selection

    - by brad
    The Problem I am working on an in-browser editor within a textarea. I have started looking for some information on dealing with textarea selection and found this jQuery plugin that does some simple manipulation. However, it doesn't explain what's going on. The Question Where can I find a good resource on Textarea Selection in JavaScript, preferably with a description of both pre-DOM3 and post-DOM30 scenarios? [Edit] In a great answer from Borgar, I have found several different places to start with contentEditable, selectionStart, and selectionEnd. I'll be looking into these things and posting any good tutorials I might find.
