  • Kohana 3 Auto loading Models

    - by pigfox
    I'm attempting to use a Model but I get a fatal error so I assume it doesn't autoload properly. ErrorException [ Fatal Error ]: Class 'Properties_Model' not found The offending controller line: $properties = new Properties_Model; The model: class Properties_Model extends Model { public function _construct() { parent::_construct(); } } I also put the class in three different locations hoping one would work, all there failed. They are: application/classes/model application/model application/models What am I missing?

  • Socket Communication C#- IP Address

    - by Ahmet Altun
    I have a socket application which I can use in local network, at home. I can make them communicate for example from 192.168.x.x to 192.168.y.y ip addresses. What should I do if I want to use the application over internet, from a remote machine, not local. For example which ip addresses should I use if my friend who lives another country wants to access my application.

  • How do Go web apps function from a server perspective?

    - by Metropolis
    Hey Everyone, I followed the directions on how to create web applications using Go, and I was able to get an application working great. One thing I am confused about though is, when you run the application (./8.out), the terminal will sit there and listen on port 8080 until somebody accesses a page. Does the terminal need to stay up all of the time to run the web application? Does the application act like apache? Does apache need to be run next to this app? Setting this up on a server environment seems very confusing to me right now because I dont understand what the best way to do this is. Thanks for any help on this, Metropolis

  • ZF Autoloader to load ancestor and requested class

    - by Pekka
    I am integrating Zend Framework into an existing application. I want to switch the application over to Zend's autoloading mechanism to replace dozens of include() statements. I have a specific requirement for the autoloading mechanism, though. Allow me to elaborate. The existing application uses a core library (independent from ZF), for example: /Core/Library/authentication.php /Core/Library/translation.php /Core/Library/messages.php this core library is to remain untouched at all times and serves a number of applications. The library contains classes like class ancestor_authentication { ... } class ancestor_translation { ... } class ancestor_messages { ... } in the application, there is also a Library directory: /App/Library/authentication.php /App/Library/translation.php /App/Library/messages.php these includes extend the ancestor classes and are the ones that actually get instantiated in the application. class authentication extends ancestor_authentication { } class translation extends ancestor_translation { } class messages extends ancestor_messages { } usually, these class definitions are empty. They simply extend their ancestors and provide the class name to instantiate. $authentication = new authentication(); The purpose of this solution is to be able to easily customize aspects of the application without having to patch the core libraries. Now, the autoloader I need would have to be aware of this structure. When an object of the class authentication is requested, the autoloader would have to: 1. load /Core/Library/authentication.php 2. load /App/Library/authentication.php My current approach would be creating a custom function, and binding that to Zend_Loader_Autoloader for a specific namespace prefix. Is there already a way to do this in Zend that I am overlooking? The accepted answer in this question kind of implies there is, but that may be just a bad choice of wording. Are there extensions to the Zend Autoloader that do this? Can you - I am new to ZF - think of an elegant way, conforming with the spirit of the framework, of extending the Autoloader with this functionality? I'm not necessary looking for a ready-made implementation, some pointers (This should be an extension to the xyz method that you would call like this...) would already be enough.

  • vb.net how to start a folder monitor service at runtime and pass on the folder path to monitor?

    - by mazrabul
    hi, I have the following windows service file: Imports System.ServiceProcess Imports System.IO Public Class fswService Dim fsw As FileSystemWatcher Dim lf As StreamWriter Protected Overrides Sub OnStart(ByVal args As String()) ' Add code here to start your service. This method should set things ' in motion so your service can do its work. lf = New StreamWriter(Application.StartupPath & "\fsw_lg.log") fsw = New FileSystemWatcher() fsw.Path = args(0) fsw.IncludeSubdirectories = True fsw.Filter = ".txt" fsw.EnableRaisingEvents = True AddHandler fsw.Created, New FileSystemEventHandler(AddressOf file_created) AddHandler fsw.Changed, New FileSystemEventHandler(AddressOf file_changed) AddHandler fsw.Deleted, New FileSystemEventHandler(AddressOf file_deleted) End Sub Public Sub file_created(ByVal obj As Object, ByVal e As FileSystemEventArgs) lf.WriteLine(Now.ToShortDateString & "-" & Now.ToShortTimeString & "-" & e.FullPath & "-created") End Sub Public Sub file_changed(ByVal obj As Object, ByVal e As FileSystemEventArgs) lf.WriteLine(Now.ToShortDateString & "-" & Now.ToShortTimeString & "-" & e.FullPath & "-changed") End Sub Public Sub file_deleted(ByVal obj As Object, ByVal e As FileSystemEventArgs) lf.WriteLine(Now.ToShortDateString & "-" & Now.ToShortTimeString & "-" & e.FullPath & "-deleted") End Sub Protected Overrides Sub OnStop() lf.Close() End Sub End Class i have the ServiceName set to fswService (same as class name). When I added an installer I also set the ServiceName for the ServiceInstaller1 as fswService. I want to start this service at runtime based on the user setting the path of the folder to be watched. To achieve this I have the following: Dim fsw_controller As New ServiceProcess.ServiceController fsw_controller.Start(fswService) 2 problems: first, intellisense error saying: 'fswService' is a type and cannot be used as an expression. second, I can not figure out a way to pass on to the service the path of the folder to watch (which is stored at My.Settings.userPath). I really thought this is how you start a service. Am I missing something? Your help is, as always, appreciated. Thanks

  • JS. How to replace html element with another element/text, represented in string?

    - by EL 2002
    I have a problem with replacing html elements. For example, there is a table <table><tr><td id="idTABLE">0</td><td>END</td></tr></table> (it can be div, span, anything) And string in JS script var str='<td>1</td><td>2</td>'; (it can be anything, '123 text', '<span123 element</span 456' or ' <tr<td123</td ' or anything) How can I replace element 'idTABLE' with str? I mean really replace, so <table><tr><td id="__TABLE__">0</td><td>END</td></tr></table> becomes <table><tr><td>1</td><td>2</td><td>END</td></tr></table> //str='<td>1</td><td>2</td>'; <table><tr>123 text<td>END</td></tr></table> //'123 text' <table><tr> tr><td>123</td> <td>END</td></tr></table> //' <tr><td>123</td> ' I tried with createElement, replaceChild, cloneNode, but with no result at all =(

  • Jet Database (ms access) ExecuteNonQuery - Can I make it faster?

    - by bluebill
    Hi all, I have this generic routine that I wrote that takes a list of sql strings and executes them against the database. Is there any way I can make this work faster? Typically it'll see maybe 200 inserts or deletes or updates at a time. Sometimes there is a mixture of updates, inserts and deletes. Would it be a good idea to separate the queries by type (i.e. group inserts together, then updates and then deletes)? I am running this against an ms access database and using vb.net 2005. Public Function ExecuteNonQuery(ByVal sql As List(Of String), ByVal dbConnection as String) As Integer If sql Is Nothing OrElse sql.Count = 0 Then Return 0 Dim recordCount As Integer = 0 Using connection As New OleDb.OleDbConnection(dbConnection) connection.Open() Dim transaction As OleDb.OleDbTransaction = connection.BeginTransaction() 'Using cmd As New OleDb.OleDbCommand() Using cmd As OleDb.OleDbCommand = connection.CreateCommand cmd.Connection = connection cmd.Transaction = transaction For Each s As String In sql If Not String.IsNullOrEmpty(s) Then cmd.CommandText = s recordCount += cmd.ExecuteNonQuery() End If Next transaction.Commit() End Using End Using Return recordCount End Function

  • Is it possible to start an activity in a different apk using startActivity on Android using the acti

    - by icecream
    I have tried to write an Android application with an activity that should be launched from a different application. It is not a content provider, just an app with a gui that should not be listed among the installed applications. I have tried the code examples here and it seems to be quite easy to launch existing providers and so on, but I fail to figure out how to just write a "hidden" app and launch it from a different one. The basic use case is: App A is a normal apk launchable from the application list. App B is a different apk with known package and activity names, but is is not visible or launchable from the application list. App A launches app B using the package and class names (or perhaps a URI constructed from these?). I fail in the third step. Is it possible to do this?

  • How Do you Declare a Dependancy Property in VB.Net 3.0

    - by discwiz
    My company is stuck on .Net 3.0. The task I am trying to tackle is simple, I need to bind the IsChecked property of the CheckBoxResolvesCEDAR to the CompletesCEDARWork in my Audio class. The more I read about this it appears that I have to declare CompletesCEDARWork as dependancy propert, but I can not find a good example of how this is done. I found this example, but when I pasted into my code I get an "is not defined" error for GetValue and I have not successfully figure out what MyCode is supposed to represent. Any help/examples would be greatly appreciated. Thanks Public Shared ReadOnly IsSpinningProperty As DependencyProperty = DependencyProperty.Register("IsSpinning", GetType(Boolean), GetType(MyCode)) Public Property IsSpinning() As Boolean Get Return CBool(GetValue(IsSpinningProperty)) End Get Set(ByVal value As Boolean) SetValue(IsSpinningProperty, value) End Set End Property Here is my slimed down Audio Class as it stands now.

  • How do I gain permissions to a Sql Compact Database?

    - by Quenton Jones
    I have an Sql Compact Database v3.5 that I'm bundling with my application. When the application is installed, the database is copied into the application's Program Files directory. Because of Vista and Win7's security settings, the installed application can't access the database file. It is merely a problem of having the database file reside in the Program Files. The solution I have thought of is to copy the file into Program Data, but does anyone have another solution? I am sure others have come across a similar problem. Thanks in advance for your input.

  • Windows Installer (C#) error code 2869

    - by KP
    I have a project, in VS 2005, which has a console application and a setup project associated to install the application. I also have an installer class in the console application that the setup project will use to do some validation before installation. Those tasks are checking the database connection string and checking some directory locations to make sure they exist prior to installation. I am getting an error code of 2869 when I try to install the application. All the code is written in C#. I have googled for this error code on Windows XP, but only found articles that deal with Vista and Windows 7. Any ideas what might be happening? Is there a workaround?

  • How do I define the default background color for window instances in a shared ResourceDictionary?

    - by Nicholas
    I can't seem to set a default background color for all of my windows in my application. Does anyone know how to do this? Currently I'm setting a theme in my App.xaml file like this. <Application> <Application.Resources> <ResourceDictionary Source="Themes/SomeTheme.xaml" /> This basically styles my entire application. Inside of SomeTheme.xaml I am trying to set a default color for all of my windows like this. <Style TargetType="{x:Type Window}"> <Setter Property="Background" Value="{DynamicResource MainColor}" /> </Style> This syntax works on a type of Button, but is completely ignored for Window. What am I doing wrong? Is there something special I have to do for a Window type.

  • Best Practice for creating Web Services

    - by Holograham
    To preface I am new to web development. I am looking at creating a core set of RESTful web services around a valuable document library of sorts (initial CRUD abilities). In doing so I am theoretically creating a perfectly re-usable and scalable back-end to be used by unanticipated applications in the future. My question centers around the best practice for doing this. My initial requirement has me also creating a unique front end. Would I make the front end and back end completely separate projects to enhance the re-usability. It would increase overhead. Looking at using GWT, Restlet, and JEE technology stack if this influences the setup at all.

  • What to return as an iterator when there is no container?

    - by DaClown
    I have an inheritance structure of objects with begin() and end() as pure virtual member functions in the base class. From this objects I'm planning to build a composite structure. This inner objects have std::vector member the begin() and end() get their data from. But in a leaf class there is no vector. Now I try to find a return value for begin() and end() in the leaf classes. What would be a good way to do that? The easiest way would be to have a vector member in the leaf classes with no elements in it to fuel begin() and end(), but this just doesn't feel right.

  • Strange behavior with large Object Types

    - by Peter Lang
    I recognized that calling a method on an Oracle Object Type takes longer when the instance gets bigger. The code below just adds rows to a collection stored in the Object Type and calls the empty dummy-procedure in the loop. Calls are taking longer when more rows are in the collection. When I just remove the call to dummy, performance is much better (the collection still contains the same number of records): Calling dummy: Not calling dummy: 11 0 81 0 158 0 Code to reproduce: Create Type t_tab Is Table Of VARCHAR2(10000); Create Type test_type As Object( tab t_tab, Member Procedure dummy ); Create Type Body test_type As Member Procedure dummy As Begin Null; --# Do nothing End dummy; End; Declare v_test_type test_type := New test_type( New t_tab() ); Procedure run_test As start_time NUMBER := dbms_utility.get_time; Begin For i In 1 .. 200 Loop v_test_Type.tab.Extend; v_test_Type.tab(v_test_Type.tab.Last) := Lpad(' ', 10000); v_test_Type.dummy(); --# Removed this line in second test End Loop; dbms_output.put_line( dbms_utility.get_time - start_time ); End run_test; Begin run_test; run_test; run_test; End; I tried with both 10g and 11g. Can anyone explain/reproduce this behavior?

  • Looping differences in Ruby using Range vs. Times

    - by jbjuly
    I'm trying to solve a Project Euler problem using Ruby, I used 4 different looping methods, the for-loop, times, range and upto method, however the for-loop and times method only produces the expected answer, while the range and upto method does not. I'm assuming that they are somewhat the same, but I found out it's not. Can someone please explain the differences between these methods? Here's the looping structure I used # for-loop method for n in 0..1 puts n end 0 1 => 0..1 # times method 2.times do |n| puts n end 0 1 => 2 # range method (0..1).each do |n| puts n end 0 1 => 0..1 # upto method 0.upto(1) do |n| puts n end 0 1 => 0

  • How do you handle options that can't be used together with OptionParser?

    - by Joel
    My Python script (for todo lists) is started from the command line like this: todo [options] <command> [command-options] Some options can not be used together, for example todo add --pos=3 --end "Ask Stackoverflow" would specify both the third position and the end of the list. Likewise todo list --brief --informative would confuse my program about being brief or informative. Since I want to have quite a powerful option control, cases like these will be a bunch, and new ones will surely arise in the future. If a users passes a bad combination of options, I want to give an informative message, preferably along with the usage help provided by optparse. Currently I handle this with an if-else statement that I find really ugly and poor. My dream is to have something like this in my code: parser.set_not_allowed(combination=["--pos", "--end"], message="--pos and --end can not be used together") and the OptionParser would use this when parsing the options. Since this doesn't exist as far as I know, I ask the SO community: How do you handle this?

  • How does Crystal Reports Runtime Licensing work?

    - by GluedHands
    I am designing an application in C# and I want to use some Crystal Reports in my application. I am selling this application as freelance to a small business. This is my first program that I have ever sold. I have Crystal Reports 2008 that I am using to design reports with. Do I need to get any kind of licensing from Business Objects to include the Crystal Reports Runtime for report printing in my application? Or do I not need to worry about it as long as I have a licensed version of Crystal Reports 2008 on my development machine. The client would only need be able to print the reports that I have designed on my machine, not design their own. The reports would be saved as a file. The application will load the saved report and print it with provided data. I did see this article which answers the most part of my question. However, it does not include whether it covers loading saved report documents? Any additional related information for a commercial product newbie is gladly appreciated.
