  • Should I use Drupal or Kohana-type framework for a web "application"

    - by Andres
    The debate is that I need a PHP Framework/Drupal with the flexibility to add custom features to a potentially large application (web and with an api). However, with a framework, like Kohana, I see myself tackling and re-inventing the wheel with the simple stuff like account management and cms stuff. Account management and quick data collection, like fast form creation, are tedious in Kohana but appear incredible simple in Drupal. On the other hand, based on my limited Drupal experience, I doubt building rapid custom "features" and allowing users to create "groups" and to manage their own roles within those groups is something Drupal can easily accomplish. To simplify, is Drupal capable of true Web Applications; where the application is a service and provides custom results to each user? Can it provide a dashboard-like interface for users to change their settings or preferences? Can it aggregate data from particular users to provide better results/info to others? If so, please point me to some knowledge :-)

  • Rotate a feature Image in Open Layers

    - by Ozaki
    I have an open layers map. It adds and removes my "imageFeature" every 10secs or so. I have a JSON feed that gives me the rotation that I need, I have a request to get that rotation and set it as a variable of rotationv. Everything works but the fact when the image is recreated it does not update the rotation. My code is as follows: JSON request: var rotationv = (function () { rotationv = null; $.ajax({ 'async': false, 'global': true, 'url': urldefault, 'dataType': "json", 'success': function (data) { rotationv = data.rotation; } }); return rotationv })(); Creating image feature: imageFeature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(mylon, mylat), { rotation: rotationv } ); The image is set in the styling elsewhere. Why does this not rotate my image?

  • Exception handling in Boost.Asio

    - by Alex B
    Boost.Asio documentation suggests the following exception handling pattern: boost::asio::io_service io_service; ... for (;;) { try { io_service.run(); break; // run() exited normally } catch (my_exception& e) { // Deal with exception as appropriate. } } The problem with it is that the context of exception is lost at the point when it's handled. For example, if I have multiple socket sessions going on, I don't know which one caused the exception to be thrown. What would be a better way to handle the exceptions from asynchronous handlers without wrapping them in try/catch blocks?

  • C# define string format of double/floats to be US english by default

    - by neil
    Hi, I have got several thousands of lines of a web application source code, initially written on a US development system, to maintain. It makes heavy use of SQL statement strings, which are combined on the fly, e.g. string SQL = "select * from table where double_value = " + Math.Round(double_value, 2); Don't comment on bad programming style, that doesn't help me in this case :) The cruix: My system uses a German locale, which in turn leads to wrong SQL statements, like this: "select * from table where double_value = 15,5" (Note the comma as decimal separator instead of a point). Question: What is the most "elegant" way to change the locale of the web app in this case) to US or UK in order to prevent being forced to change and inspect every single line of code? .net 3.5 is not an option (would give me the chance to overwrite ToString() in an extension class) Kind regards

  • WPF TreeView PreviewMouseDown on TreeViewItem

    - by imekon
    If I handle the PreviewMouseDown event on TreeViewItem, I get events for everything I click on that TreeViewItem include the little +/- box to the left (Windows XP). How can I distinguish that? I tried the following: // We've had a single click on a tree view item // Unfortunately this is the WHOLE tree item, including the +/- // symbol to the left. The tree doesn't do a selection, so we // have to filter this out... MouseDevice device = e.Device as MouseDevice; // This is bad. The whole point of WPF is for the code // not to know what the UI has - yet here we are testing for // it as a workaround. Sigh... // This is broken - if you click on the +/- on a item, it shouldn't // go on to be processed by OnTreeSingleClick... ho hum! if (device.DirectlyOver.GetType() != typeof(Path)) { OnTreeSingleClick(sender); } What I'm after is just single click on the tree view item excluding the extra bits it seems to include.

  • Eclipse RCP : make a standalone plugin extending an existing standalone one

    - by akira2x3x
    I have extended via extension point (add menus and functionnalities) an already existing plugin which has it's own product definition file and it's own class Application implements IApplication. I want to create a Product Configuration(customize splash screen,etc...). Does my plugin need an Application class? I want my plugin to be independant, Standalone with a launcher. Not a fragment. Do I have to inherit already existing plugin Application? Thanks for the tips and tricks.

  • What's all the hype over objectsets in Entity Framework 4?

    - by Kohan
    I am an intermediate user of EF in .net 3.5 and have recently moved to working with .net 4. One thing i keep coming across when reading various tutorials is the use of ObjectSets instead of ObjectQuerys and that they are a great new feature. What is so great about them? Reading this MSDN article titled "Working with ObjectSet (Entity Framework)" It shows two examples on how to add a Product.. one for 3.5 and another for 4.0. http://msdn.microsoft.com/en-us/library/ee473442.aspx Through my lack of knowledge I am possibly bringing up a seperate point here, but i never added a Product like this: //In .NET Framework 3.5 SP1, use the following code: using (AdventureWorksEntities context = new AdventureWorksEntities()) { // Add the new object to the context. context.AddObject("Products", newProduct); } I would have just used context.AddToProducts(newProduct); Please enlighten me. Kind regards, Kohan

  • Dynamically creating a treeview in HTML with indent lines in ASP.Net

    - by Ben
    Hi, im quite new to HTML, and am trying to create a proffessional looking TreeView. I can not use the in built treeview in ASP.Net as i need to point the target of the selection to another frame (I have tried, and this doesn't seem possible). My treeview is built up as follows: Folder1 ChildOne ChildTwo ChildThree Folder2 ChildOne ChildTwo ChildThree I have the collapsing of the folders working, but would like to know how to format this treeview so it has dotted lines down to the child nodes (as most treeviews tend to have). How would i go about this? Cheers.

  • How to rebind another UDP socket port properly?

    - by Jollian
    When my client application launchs, it binds the UDP port like this: this.BindPort(5001); The BindPort method implement blow: public void BindPort(int port) { m_listener = new Socket( AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp ); IPEndPoint Point = new IPEndPoint( IPAddress.Any, Port ); m_listener.Bind( port); m_listener.BeginReceive( buff, 0, buff.Length, SocketFlags.None, new AsyncCallback( DataReceived ), buff ); } And when my server application commands client to bind to another UDP port(e.g. 5005). I call the same BindPort method in client. Then a exception occurs at DataReceived method. I think there must be a problem that I don't close the UDP port properly. But how can i close the UDP socket properly and rebind to another one. Thanks.

  • How to make a remote connection to a MySQL Database Server?

    - by MLB
    Hello: I am trying to connect to a MySQL database server (remote), but I can't. I am using an user with grant privileges (not root user). The error message is the following: Can't obtain database list from the server. Access denied for user 'myuser'@'mypcname' (using password: YES) "myuser" is an user I created with grant access. This user allows me to connect locally to every database. I am using the same software versions in both hosts: MySQL Server 4.1 (server) and EMS SQL Manager 2005 for MySQL, edition 3.7.0.1 (client). The point is that I need to connect to the remote server using a different user, not root user. So, how to make the connection? Thanks.

  • How to partially update views in an app widget without rebuilding all the RemoteViews

    - by Gianni Costanzi
    I'm implementing an app widget and I'd like to be able to change the property of a single view in the widget layout, without rebuilding all the RemoteViews from scratch, which involves loading XML etc and which is not necessary in some circumstances.. Is there a way to say "update property X on view identified by a specific ID in the current widget layout"? I've seen that there is a partiallyUpdateAppWidget method in the AppWidgetManager class but I can't understand nor if it is meant for this purpose neither how it must be used.. Can you help me or point me to a useful link or example?

  • Getting strange response on calling verifyReceipt to verify an in-app

    - by lostInTransit
    Hi I am making a call to verifyReceipt to validate an in-app purchase but am getting a very strange response (the response is b) The same code worked till some time back. But I stopped the app debugging while the trans was being verified at one point. From there on, the only response I get is b. I checked the code and it has nothing wrong. As I said, the same code worked till I stopped this trans mid-way. Any idea what could be wrong? Thanks.

  • pgp key information

    - by calccrypto
    can someone show a description of the information of what a pgp looks like if only the descriptions were there but not the actual information? something like (i dont remember if the values are correct): packet-type[4 bits], total length in bytes[16 bits], packet version type [4 bits], creation-time[32 bits], encryption-algorithm[8 bits], ...,etc,etc ive tried to understand rfc4880, but its tedious and confusing. so far, i am think i have extracted the 4 i wrote above, but i cant seem to get the rest of the information out. can anyone help? i know i can just find some pgp program, but the whole point of this is to allow me to learn how those programs work in the first place

  • Are concurrency issues possible when using the WCF Service Behavoir attribute set to ConcurrencyMode

    - by Brandon Linton
    We have a WCF service that makes a good deal of transactional NHibernate calls. Occasionally we were seeing SQL timeouts, even though the calls were updating different rows and the tables were set to row level locking. After digging into the logs, it looks like different threads were entering the same point in the code (our transaction using block), and an update was hanging on commit. It didn't make sense, though, because we believed that the following service class attribute was forcing a unique execution thread per service call: [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.PerCall)] We recently changed the concurrency mode to ConcurrencyMode.Single and haven't yet run into any issues, but the bug was very difficult to reproduce (if anyone has any thoughts on flushing a bug like that out, let me know!). Anyway, that all brings me to my question: shouldn't an InstanceContextMode of PerCall enforce thread-safety within the service, even if the ConcurrencyMode is set to multiple? How would it be possible for two calls to be serviced by the same service instance? Thanks!

  • Python - How to find a correlation between two vectors ?

    - by psihodelia
    Given two vectors X and Y I have to find their correlation, i.e. their linear dependence/independence. Both vectors have equal dimension. A resulted answer should be a floating point number from [-1.0 .. 1.0]. Example: X=[-1, 2, 0] Y=[ 4, 2, -0.3] Find y=cor(X,Y) such that y belongs to [-1.0 .. 1.0]. It should be a simple construction involving a list-comprehension. No external library is allowed. UPDATE: ok, if dot product is enough, then here is my solution: nX = 1/(sum([x*x for x in X]) ** 0.5) nY = 1/(sum([y*y for y in Y]) ** 0.5) cor = sum([(x*nX)*(y*nY) for x,y in zip(X,Y) ]) right?

  • IIS7 301 Redirect from a List of URLs

    - by corymathews
    Recent changes are forcing me to add a bunch of 301 redirects. Seems that IIS7 is my best bet as compared to redirects within the files. I have found how to add them 1 by 1 but this requires the page/folder to exist (which most don't anymore(and creating them seems to defeat the point of the redirect)) and does not work on dynamic urls. I also cannot go to every page and add the redirects at the page level because some older pages are in php which is no longer supported on the new server. There is also no obvious pattern to the changes so each one must be made on its own. samples of the redirects page.htm - /page/ /folder/folder/ - /folder/folder.cfm /folder/folder/ - /folder/ /page.php?id=1 - page.htm

  • When are reference files(dlls) loaded?

    - by Daniel
    I wrote a program that makes a reference to Microsoft.Web.Administration.dll, which is not present on Windows Server 2003. The program checks for the os and does not reference the dll if the os is 2003. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //reference the Microsoft.Web.Administration.dll file.<br> When I tested this program on Windows Server 2003, an error occured telling me it couldn't locate the Microsoft.Web.Administration.dll. But when I separated the if-else block into 2 different methods as below, and the error did not occur. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //DoIt2008Style(); So I wanted to know about reference file loading time in more detail. could you point me to some resources?

  • How do i return a StringWriter When I cant Clone it?

    - by acidzombie24
    My code looks like the below. Obviously i cant write 'ok' because the object has been disposed. I cant do return sw.Clone() bc clone doesnt exist. If i dont use a using then at any point between = new and return (like iterating and writing to the object as my example doesnt do) can have an exception and thus not disposing the object. Am i to define sw outside of a try block and check if its null then dispose in a catch block? That seems like a bit of excessive work. Is there a better way? is that the only way? static void func1() { using (var sw = func2()) { sw.WriteLine("Ok"); } } static StringWriter func2() { using (var sw = new StringWriter()) { return sw; } }

  • JSTL Session Lookup - Key Has Periods

    - by John W.
    Hello All, I am working with some legacy code, and at some point there is a key in the session that is something like session.setAttribute("com.org.something.Object",someObject); Now trying to access this in a jsp using jstl is a bit difficult becuase if I tried it like I normally would I would do: ${sessionScope.com.org.something.Object.someFieldGetter} As most of us can imagine it will fail because there is no com object in session scope. I also tried ${sessionScope.'com.org.something.Object'.someFieldGetter} And a parsing error was thrown. Does anyone know how to resolve this so that I can correctly get the object similar to session.getAttribute("com.org.something.Object") but through jstl? thank you.

  • Socket programming and telnet with VB.net

    - by Mike
    I'm writing a GUI-based app in VB.net that talks to a LambdaMOO server via telnet, sends commands to display the object hierarchy, then parses the output and creates a visual representation of the object hierarchy. So my question is: is there some kind of "telnet client" class for .NET to simplify the sending and receiving of data, or do I have to write my own using the socket API? Does Mono have something like this? Barring an easy solution, does anyone have a good tutorial they can point to for telnet client programming in VB.net?

  • Jquery and binding an event to an iframe

    - by dbr
    **I'm currently using a jquery textselect plugin to fire alerts based on the selection text anywhere on the page and it works just fine doing something like: $(document).ready(function() { $(document).bind('textselect', function(e) { alert(e.text); }); }); I've since had to add an iframe to the page and I need the text selection to work on text within the iframe as well. I'm trying to do something like this but it's not working: $(document).ready(function() { $('#iframeId').load(function() { $(document.getElementById("iframeId").contentWindow).bind('textselect',function(e) { alert(e.text); }); }); At this point I've tried a whole mess of ways to reference the iframe document without any success. Any ideas?**

  • How can I get to the value of my WPF UserControl DependencyProperty from UI Automation Framework?

    - by Surfbutler
    Hi, I'm having trouble getting access to my WPF UserControl DependencyProperty values through the UI Automation Framework. I've used James McCaffreys article in MSDN as a starting point (Automating IO Tests in WPF Applications, MSDN March 2009), but I can only see properties etc in standard controls such as buttons. I'm assuming there's some Automation interface I have to implement on my UserControl, but what and how? I can already see my control fine e.g. in UISpy, but I can't see the dependency properties within it. Here's what my usercontrol looks like currently in UISpy: AutomationElement General Accessibility AccessKey: "" AcceleratorKey: "" IsKeyboardFocusable: "False" LabeledBy: "(null)" HelpText: "Switches 48v Phantom Power On/Off (for Mic inputs only)." State IsEnabled: "True" HasKeyboardFocus: "False" Identification ClassName: "" ControlType: "ControlType.Custom" Culture: "(null)" AutomationId: "V48SwL" LocalizedControlType: "custom" Name: "" ProcessId: "5684 (VirtualSix)" RuntimeId: "7 5684 40026340" IsPassword: "False" IsControlElement: "True" IsContentElement: "True" Visibility BoundingRectangle: "(140, 457, 31, 20)" ClickablePoint: "155,467" IsOffscreen: "False" ControlPatterns

  • algorithm advice for finding maximum items within a time period

    - by darren
    Hi everyone. I have a database schema that is similar to the following: | User | Event | Date |--------|---------------|------ | 111 | Walked dog | 2009-10-1 | 222 | Walked dog | 2009-10-2 | 333 | Fed Fish | 2009-10-5 | 222 | Did Laundry | 2009-10-6 | 111 | Fed Fish | 2009-10-7 | 111 | Walked dog | 2009-10-18 | 222 | Walked dog | 2009-10-19 | 111 | Fed Fish | 2009-10-21 I would like to produce a query that returns the maximum number of times a user performs some action within a time period. For example, given a time period of 5 days, what is the maximum number of times user 111 walked the dog? The most obvious solution would be to start at some zero point and move forward each day, summing up 5 day periods along the way, then taking the maximum total out of all the 5 day windows. the approach seems incredibly costly however. I would appreciate any suggestions you may have.

  • Getting progress status out of a class library method

    - by Richard
    This app that I am doing uses a class library (if I dare call it that) to do the bulk of the work: 2 main methods in there (DoWork and UndoWork) use the other classes to achieve thier goal. Now that that works, I want to get out of the Console test enviroment and do a GUI. How would I get the status of say, the DoWork() method to update a progress bar? Should I multilate the class library (which currently works with the Console and Windows.Forms) to update? The problem with that is that I would surely have to make the class library use Window.Forms which will mess up the console testing apps (And there are lots of them - I tested all the way through, and then all together). Could you suggest some ideas, or places I can read up about ideas (the whole point of writing this this program is to learn, afer all)? Oh, by the way, suggestions like "foresight" or "planning" probably won't help here...(now, anywyay!) - But certainly will in future projects!
