  • PHP: OOP and methods

    - by Pirkka
    Hello I`ve been wondering how to implement methods in a class. Could someone explain me what means if one does OOP in procedural style? Here is an example: class Fld extends Model { private $file; private $properties = array(); public function init($file) { $this->file = $file; $this->parseFile(); } private function parseFile() { // parses the file foreach($this->file as $line)...... .................. $this->properties = $result; } } I mean is it a good thing to have methods like these that do operations for the class properties like that. Or should I pass the class property as method parameter... I mean this would cause error if the file property wouldnt be declared.

  • Entity framework (3.5): How to translate a certain LINQ query to eSQL?

    - by Sebastian P.R. Gingter
    Hi there, I have the following LINQ query that I need to translate to Entity SQL /eSQL): return (ObjectQuery<User>) from user in Users where !user.Roles.Any(r => r.AnIntegerProperty < 0) select user; User.Roles is an navigation property to the n:m relation to Roles and there also is a Role.Users navigation property the other way round. There aren't User_Roles or Roles_User Entities available in the model, and I can't add these. I also can't use the LINQ statement here, because I need to add .OrderBy("it." + propertyname) (comes from another source, can't change that too) later on which is not possible if the ObjectQuery is build with linq. So how do I translate this to eSQL? And where can I find good eSQL samples? I searched for a whole day until now and must admit that eSQL reference is lousy and there aren't any usable examples around the web.

  • How to find a label in a asp repeater

    - by citrus
    Structure of my asp: repeater repeater updatePanel label1 (rating) button (updates rating) some_picture (thing being rated) /update panel /repeater Imagine the output of the above repeater containing 100 rows. (1 label, and 1 button on each row). Goal: when I click the button, I want the appropriate label to be updated. I dont know how to do this. I can reference a label via: Label myLabel2Update = (Label)Repeater1.Controls[0].Controls[0].FindControl("Label1"); But ofcourse, it will be the same label each time (not necessarily the label that needs to be updated). I need to update the label that is on the same row as the button. Any guidance would be appreciated.

  • Disabling mouse movement and clicks altogether in c#

    - by ThaNerd
    At work, i'm a trainer. I'm setting up lessons to teach people how to "do stuff" without a mouse... Ever seen people click "login" textbox, type, take the mouse, click "password", type their password, then take the mouse again to click the "connect" button beneath ? So i'll teach them how to do all that without a mouse (among many other things, of course) At the end of the course, i'll make them pass a sort of exam. So i'm building a little wizard based app in which i present some simili-real-life examples of forms to fill in, but i want to disable their mouse programatically while they do this test. However, further in the wizard, i'll have to let them use their mouse again. Is there a -- possibly easy -- way to just disable the mouse for a while, and re-enable it later on? I'm on C# 2.0, programming under VC# 2k5, if that matters

  • How do I temporarily monkey with a global module constant?

    - by Daniel
    Greetings, I want to tinker with the global memcache object, and I found the following problems. Cache is a constant Cache is a module I only want to modify the behavior of Cache globally for a small section of code for a possible major performance gain. Since Cache is a module, I can't re-assign it, or encapsulate it. I Would Like To Do This: Deep in a controller method... code code code... old_cache = Cache Cache = MyCache.new code code code... Cache = old_cache code code code... However, since Cache is a constant I'm forbidden to change it. Threading is not an issue at the moment. :) Would it be "good manners" for me to just alias_method the special code I need just for a small section of code and then later unalias it again? That doesn't pass the smell test IMHO. Does anyone have any ideas? TIA, -daniel

  • Problems with PHP System_Daemon and IMAP connection.

    - by mike
    I'm trying to create a PHP daemon that connects to an IMAP server and processes emails as they come in. I have it close to working, but the daemon keeps grabbing the original emails that it finds the first time the daemon is loaded. I believe the reason is because I'm opening the IMAP connection in the parent process. Example below: if ($imapConnection=imap_open($authhost,$user,$pass) or die()) { //start daemon while() { //Grab email headers $imapHeaders = imap_headers($imapConnection); $count = sizeof($imapHeaders) //loop the emails for($i = 1; $i <= $count, $i++) { //process the email //delete the email } System_Daemon::iterate(15); } } imap_close($imapConnection); I'd like to stay away from putting the IMAP connection within the loop. How can I keep the connection to the IMAP server outside of the loop and still get new emails?

  • Best way to store 3 pieces of data as a single entry

    - by Matt
    For a game server, I want to record details when a player makes a kill, store this, and then at intervals update to a sql database. The part i'm interested in right now is the best method of storing the kill information. What i'd like to pass to the sql server on update would be {PlayerName, Kills, Deaths}, where the kills and deaths are a sum for the period between updates. So i'm assuming i'd build a list along the lines of {bob, 1, 0} {frank, 0, 1} {tom, 1, 0} {frank, 0, 1} then on update, consolidate the list to {frank, 14, 3}etc Can someone offer some advice please?

  • External class-calling

    - by anonymous
    Hi guys i have a bit of a problem with a few classes, and i would be very grateful if someone can help me out. So i have: Already compiled executable (for whom i don't have the source) A class in that program that i want to call The program doesn't have export for the class, and that's my problem i don't have definition for this class, so is there a way to get a callback to this class? Example: In the compiled executable: foo::bar (example) { printf(example); } My app: CALLBACK(foo::bar, "this text must be passed as argument") Or in other words i want to call a class in other executable (without having its source) and pass arguments to its function.

  • How do I modify this download function in Python?

    - by TIMEX
    Right now, it's iffy. Gzip, images, sometimes it doesn't work. How do I modify this download function so that it can work with anything? (Regardless of gzip or any header?) How do I automatically "Detect" if it's gzip? I don't want to always pass True/False, like I do right now. def download(source_url, g = False, correct_url = True): try: socket.setdefaulttimeout(10) agents = ['Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)','Mozilla/4.0 (compatible; MSIE 7.0b; Windows NT 5.1)','Microsoft Internet Explorer/4.0b1 (Windows 95)','Opera/8.00 (Windows NT 5.1; U; en)'] ree = urllib2.Request(source_url) ree.add_header('User-Agent',random.choice(agents)) ree.add_header('Accept-encoding', 'gzip') opener = urllib2.build_opener() h = opener.open(ree).read() if g: compressedstream = StringIO(h) gzipper = gzip.GzipFile(fileobj=compressedstream) data = gzipper.read() return data else: return h except Exception, e: return ""

  • Is Dynamic Casting Possible in Java

    - by Tom Tucker
    So I have a class of overloaded methods like this: class Foo { public void test(Object value) { ... } public void test(String value) { ... } } I need to pass a property value of a bean to one of these methods depending on its type, but I don't know the actual property type until the runtime. e.g. public void run(Object bean, String propertyName) { Foo foo = new Foo(); foo.test(PropertyUtils.getProperty(bean, propertyName)); } BTW, PropertyUtils.getProperty() is a helper method that returns a value of the specified property on a bean. PropertyUtils.getProperty() returns an Object, so that test(Object value) will be always called and the actual property type will be ignored. I can figure out the propery type in the runtime, even if its value is null. Is there such a thing as dynamic casting in Java? If not, is there a way to have an overloaded method with the correct parameter type called?

  • With ASP .NET, how do I display a side submenu depending on what user picked from the main menu?

    - by Ole Media
    Hello, I come from PHP side, but I'm in need to develop a site using ASP .NET So far I manage to create a master page. Now I'm dealing with menus and submenus What I'm trying to do is, if the user picks "About Us" from the main menu, under the about us page I want to display a submenu with the options "who we are, what we do, contact us" If the user picks "Our Products" from the main menu, then under the products page I want to display a submenu with the options "product 1, product 2, product 3" Is this possible with only one master page? I read something about menu control but not sure that is what I need. So far I found how to display a sitemap, but not specific sections of a sitemap, if this is the way to do things. Any links, sample code, point of reference will be appreciated. Thanks

  • python class attribute

    - by chnet
    Hi, i have a question about class attribute in python. class base : def __init__ (self): pass derived_val = 1 t1 = base() t2 = base () t2.derived_val +=1 t2.__class__.derived_val +=2 print t2.derived_val # its value is 2 print t2.__class__.derived_val # its value is 3 The results are different. I also use id() function to find t2.derived_val and t2.class.derived_val have different memory address. My problem is derived_val is class attribute. Why it is different in above example? Is it because the instance of class copy its own derived_val beside the class attribute?

  • IO completion port key confusion

    - by Richard Tew
    I'm writing an IO completion port based server (source code here) using the Windows DLL API in Python using the ctypes module. But this is a pretty direct usage of the API and this question is directed at those who have a knowledge of IOCP, not Python. As I understand the documentation for CreateIoCompletionPort, you specify your "user defined" completion key when you call this function with a file handle (in my case a socket) you are associating with the created IOCP. When you get around to calling GetQueuedCompletionStatus, you get a completion key value along with a pointer to an overlapped object. The completion key should identify what overlapped object and request has completed. However, let's say I pass in 100 as the completion key in my CreateIoCompletionPort call with an overlapped object. When the same overlapped object has its IO completed and it arrives back through GetQueuedCompletionStatus, the completion key that accompanies it is much larger and bares no resemblance to the original value of 100. Am I misunderstanding how the completion key works, or must I be doing it wrong in the source code I linked above?

  • C# event or delegate or other solution?

    - by user295734
    Looking for some help or programmng ideas or mayeb there is some pattern that would help. Have an application that needs to fire alot of events sequentially, it could up to 100 or more unique events, it will be dynamic depeneding on the situation. Trying to find the best practice for doing this. My main idea right now is to create a list of objects iterate thru them, and fire each event. This seems wrong, or bad practice. Or maybe have one object and pass a list or params into one event? Or am I missing some feature in .NET that i could be using or implementing?

  • Loose Coupling of Components

    - by David
    I have created a class library (assembly) that provides messaging, email and sms. This class library defines an interface IMessenger which the classes EmailMessage and SmsMessage both implement. I see this is a general library that would be part of my infrastructure layer and would / can be used across any development. Now, in my application layer I have a class that requires to use a messaging component, I obviously want to use the messaging library that I have created. Additionally, I will be using an IoC container (Spring.net) to allow me to inject my implementation i.e. either email or sms. Therefore, I want to program against an interface in my application layer class, do I then need to reference my message class library from my application layer class? Is this tightly coupling my application layer class to my message class library? Should I be defining the interface - IMessenger in a seperate library? Or should I be doing something else?

  • Passing in a value to a usercontrol through a foreach loop

    - by LooDaFunk
    in my asp.net mark up I have a foreach loop that iterates through a simple list. In this foreach loop I am adding a new user control and attempting to pass in the value from the loop. However, this value just wont budge and get inside that damn control! Anyone have any suggestions? <%foreach (userInfo i in this.items) { %> <uc1:ItemControl ID="ItemControl" runat="server" UserID='<%#Eval("userID") %>'/> <%} %> userID is a public property in the control, when it goes to set, the value is just literally : <%#Eval("userID") %. I've tried #Bind and =Value but nothing seems to work. Any help would be appreciated!

  • Automatically copy new Jar file to Tomcat project WEB-INF/lib folder

    - by The D Williams
    I am developing a Tomcat app (actually it's a Red5 app, but this is effectively the same). This contains the usual /WebContent/WEB-INF/lib folder, which is where I locate the various jars it uses. Recently, I pulled a package out of my app project, and converted into a separate Jar project which was then released as open source (this resides in the same workspace). What I want, is that when I build my Tomcat app, that Eclipse automatically pulls the latest version of the Jar I have built into its /WebContent/WEB-INF/lib folder. This is the behaviour you get with .NET when you reference one project from another, and I guess this is why I was expecting to find some way of doing it. At the moment, I have to manually copy/paste the Jar across each time I build it. Of course, ideally when I build my Tomcat app it would automatically detect if the Jar project was up-to-date too, and build it if not. Any suggestions most gratefully received.

  • InvalidOperationException when using soap client

    - by codymanix
    I've added as wsdl file using the add servece reference dialog in vs2008. MyService serviceproxy = new MyService(); When I instantiate the service proxy, I get an InvalidOperationException with the following text (translated from german): Could not find default endpoint element to the contract "ServiceName.ServiceInterface" in the service model refers client configuration section. This may be because: The application configuration file was not found or not an endpoint in the client element item is found, which corresponded to this contract. Where servicename is the name I give the service when I add it in vs2008 and ServiceInterface the interface which is automatically generated for it.

  • iPhone OS: Posting an image + text "story" to a user's news feed through the facebook api

    - by nickthedude
    So what I am trying to do is post an image that has been created by a user on an iphone into that users newsfeed. The functionality I am having a hard time understanding if it is possible: Can I pass a local NSURL (or URL?)(to a png file that lives in the documents folder) through a JSON string and onto Facebook? i want to mimic the action of a user going to his/her facebook page, clicking into the textfield for their newsfeeld, uploading an image by clicking the "photos" icon and selecting an image from a local disk and uploading it. I would also like to add some text into the post optionally. I'm just getting started with the Facebook api and it seems pretty tough right now, any help would be appreciated. code examples appreciated. Thanks, Nick

  • C#: Problem trying to resolve a class when two namespaces are similar

    - by rally25rs
    I'm running into an issue where I can't make a reference to a class in a different namespace. I have 2 classes: namespace Foo { public class Class1 { ... } } namespace My.App.Foo { public class Class2 { public void SomeMethod() { var x = new Foo.Class1; // compile error! } } } The compile error is: The type or namespace name 'Class1' does not exist in the namespace 'My.App.Foo' In this situation, I can't seem to get Visual Studio to recognize that "Foo.Class1" refers to the first class. If I mouse-over "Foo", it shows that its trying to resolve that to "My.App.Foo.Class1" If I put the line: using Foo; at the top of the .cs file that contains Class2, then it also resolves that to "My.App.Foo". Is there some trick to referencing the right "Foo" namespace without just renaming the namespaces so they don't conflict? Both of these namespaces are in the same assembly.

  • Putting binary resources (images) in a separate assembly (WPF/.NET)

    - by haagel
    I have a .NET solution with a couple of projects. The output is a WPF application. Now I would like to put my binary resources (images/icons) in a single project/assembly in this solution, so that all my other projects in can use them. My question is how I can do that? What type of project should I create and how should I reference these resources in my XAML code (in the other projects)? I've tried quite a few things but I can't seem to get it to work...

  • WIX: Using a temporary file during install

    - by madbadger
    Hello! I am writing a WIX installer and I have a following requirement: During installation, I need to pass an absolute path to a file (lets call it A) included in my installer to a COM component, which already exists on the hard drive and is a part of another program. I have already written an appropriate Custom Action which expects a path to the file A. I don't want to include A as a file installed in the Program Files folder and removed during the uninstallation process. Instead, I would like to put A only temporary on the hard drive, call my Custom Action which will cause the COM component to use the content of A, and then remove A from disk. Is there an easy way to accomplish this goal? I have tried to utilize the Binary Table and store A there, however I don't know how to reference A using absolute path. I know I could put A outside of MSI file but I would like to keep every file installer needs in a single MSI. Any help would be appreciated.

  • What is a class outlet and where is it?

    - by chrish
    I am trying to learn iPhone development and someone passed along the website www.appsamuck.com. On Day 1, the tutorial instructs the developer We need to reference the label in our code so we can update the label * In the document window "File's Owner" * Click: Tools->Idenity Inspector * In the inspector click the + under "Class Outlets" * Change myOutlet1 to "countdownLabel" * Change id to UILabel * Click enter to make sure they commit I really don't want to get hung up on this, but I can't find "Class Outlets" either when creating a new project from scratch or opening the zipped source code project. Is this just a difference in versions of Interface Builder? Where did it go?
