  • A PHP design pattern for the model part [PHP Zend Framework]

    - by Matthieu
    I have a PHP MVC application using Zend Framework. As presented in the quickstart, I use 3 layers for the model part : Model (business logic) Data mapper Table data gateway (or data access object, i.e. one class per SQL table) The model is UML designed and totally independent of the DB. My problem is : I can't have multiple instances of the same "instance/record". For example : if I get, for example, the user "Chuck Norris" with id=5, this will create a new model instance wich members will be filled by the data mapper (the data mapper query the table data gateway that query the DB). Then, if I change the name to "Duck Norras", don't save it in DB right away, and re-load the same user in another variable, I have "synchronisation" problems... (different instances for the same "record") Right now, I use the Multiton pattern : like Singleton, but multiple instances indexed by a key (wich is the user ID in our example). But this is complicating my developpement a lot, and my testings too. How to do it right ?

  • UITableView programatically create delegate object?

    - by fuzzygoat
    I have a question regarding setting up a custom delegate class for use with UITableView. What I have done is as follows: Setup a new class (in sperate *.h and *.m files for the class) Conformed that new class to the <UITableViewDelegate, UITableViewDataSource> protocols Added the required methods. Created a pointer to the new object using @property and IBOutlet. In InterfaceBuilder created and assigned an object template to my new class Assigned the dataSource and delegate connections. This all works fine. My question is if I don't want to use interfaceBuilder to setup and instantiate my new delegate class directly in Xcode how do I go about doing that? More specifically how would I: Instantiate the delegate class, would that be created / owned by the controller? Set the dataSource and delegate connections? What is the best way of doing this? any help / information is much appreciated. Gary

  • Using a database class in my user class

    - by Josh
    In my project I have a database class that I use to handle all the MySQL stuff. It connects to a database, runs queries, catches errors and closes the connection. Now I need to create a members area on my site, and I was going to build a users class that would handle registration, logging in, password/username changes/resets and logging out. In this users class I need to use MySQL for obvious reasons... which is what my database class was made for. But I'm confused as to how I would use my database class in my users class. Would I want to create a new database object for my user class and then have it close whenever a method in that class is finished? Or do I somehow make a 'global' database class that can be used throughout my entire script (if this is the case I need help with that, no idea what to do there.) Thanks for any feedback you can give me.

  • How do functional programming languages work?

    - by eSKay
    I was just reading this excellent post, and got some better understanding of what exactly object oriented programming is, how Java implements it in one extreme manner, and how functional programming languages are a contrast. What I was thinking is this: if functional programming languages cannot save any state, how do they do some simple stuff like reading input from a user (I mean how do they "store" it), or storing any data for that matter? For example - how would this simple C thing translate to any functional programming language, for example haskell? #include<stdio.h> int main() { int no; scanf("%d",&no); return 0; }

  • ASP.NET MVC - Custom validation message for value types

    - by Giovanni Galbo
    When I use UpdateModel or TryUpdateModel, the MVC framework is smart enough to know if you are trying to pass in a null into a value type (e.g. the user forgets to fill out the required Birth Day field) . Unfortunately, I don't know how to override the default message, "A value is required." in the summary into something more meaningful ("Please enter in your Birth Day"). There has to be a way of doing this (without writing too much work-around code), but I can't find it. Any help? EDIT Also, I guess this would also be an issue for invalid conversions, e.g. BirthDay = "Hello".

  • WPF dependency property setter not firing when PropertyChanged is fired, but source value is not cha

    - by Sandor Davidhazi
    I have an int dependency property on my custom Textbox, which holds a backing value. It is bound to an int? property on the DataContext. If I raise the PropertyChanged event in my DataContext, and the source property's value is not changed (stays null), then the dependency property's setter is not fired. This is a problem, because I want to update the custom Textbox (clear the text) on PropertyChanged, even if the source property stays the same. However, I didn't find any binding option that does what I want (there is an UpdateSourceTrigger property, but I want to update the target here, not the source). Maybe there is a better way to inform the Textbox that it needs to clear its text, I'm open to any suggestions.

  • PostgreSQL Invalid Value for Parameter Warning

    - by gvkv
    In PostgreSQL 8.4.3, I get this error when logging on to one of my databases (adus): WARNING: invalid value for parameter "default_text_search_config": "tsc_markets" which makes sense since executing the command \dF does not list any such configuration (and only lists the defaults). However, when I ask psql to show me the current value: adus=# show default_text_search_config; I get default_text_search_config ---------------------------- pg_catalog.english (1 row) In addition, the postgresql.config file has the entry: # default configuration for text search default_text_search_config = 'pg_catalog.english' plus, there is only one (user) defined schema that I use (also called adus) in this database. What's going on?

  • C# Object Creation from Datatable

    - by Jonesy
    Hi Folks, Im just getting my head round C#. I've been creating classes and objects so say i created a class called Member: public class Member { public int MemberID; public string FirstName; public string LastName; public string UserName; } and i create a new object of that class by doing this: Member Billy = new Member(); Billy.UserName = "Jonesy"; Billy.FirstName = "Billy"; Billy.LastName = "Jones"; Thats all fine but what if I've queried a database and gotten back 5 members, can I create objects on the fly? Or what is the best way to store these members in memory? I've used VB.Net where I would just add them into a datatable. But I've never really done any object-oriented programming before and thought since I'm learning C sharp nows the best time to learn OOP.. Any help most appreciated! Jonesy

  • Cast an NSDictionary value while applying an NSPredicate?

    - by RickiG
    Hi I have an Array of NSDictionary objects. These Dictionaries are parsed from a JSON file. All value objects in the NSDictionary are of type NSString, one key is called "distanceInMeters". I had planned on filtering these arrays using an NSPredicate, so I started out like this: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(distanceInMeters <= %f)", newValue]; NSArray *newArray = [oldArray filteredArrayUsingPredicate:predicate]; I believe this would have worked if the value for the "distanceInMeters" key was an NSNumber, but because I have it from a JSON file everything is NSStrings. The above gives this error:* -[NSCFNumber length]: unrecognized selector sent to instance 0x3936f00** Which makes sense as I had just tried to treat an NSString as an NSNumber. Is there a way to cast the values from the dictionary while they are being filtered, or maybe a completely different way of getting around this? Hope someone can help me :)

  • Proper way to set class variables

    - by ensnare
    I'm writing a class to insert users into a database, and before I get too far in, I just want to make sure that my OO approach is clean: class User(object): def setName(self,name): #Do sanity checks on name self._name = name def setPassword(self,password): #Check password length > 6 characters #Encrypt to md5 self._password = password def commit(self): #Commit to database >>u = User() >>u.setName('Jason Martinez') >>u.setPassword('linebreak') >>u.commit() Is this the right approach? Should I declare class variables up top? Should I use a _ in front of all the class variables to make them private? Thanks for helping out.

  • Objective C: Create arrays from first array based on value

    - by Nic Hubbard
    I have an array of strings that are comma separated such as: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA Bill Gates,44,WA Bill Nye,21,OR I have those values in an NSScanner object so that I can loop through the values and get each comma seperated value using objectAtIndex. So, what I would like to do, is group the array items into new arrays, based on a value, in this case, State. So, from those, I need to loop through, checking which state they are in, and push those into a new array, one array per state. CA Array: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA WA Array: Bill Gates,44,WA OR Array: Bill Nye,21,OR So in the end, I would have 3 new arrays, one for each state. Also, if there were additional states used in the first array, those should have new arrays created also. Any help would be appreciated!

  • Minimum permissions to COM Object to Instantiate running as LocalService

    - by Paul Farry
    I'm writing a .NET Service that creates a COM object. If I run the Service as the Logged on user (everything is fine). If I run the Service as LocalSystem, everything is fine. If I run the Service as LocalService, then I get an AccessDeniedException when trying to instantiate the COM Object. I've come up with the following block to grant the necessary permissions and it appears to work correctly, but I wanted to make sure I wasn't missing something regarding the COM rules. Private Sub SetAccessToRockeyRegistry() Using reg As RegistryKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey("CLSID\{EE0680D3-AAC3-446B-AFD7-F9DE2D3E28FB}", True) Dim sec As RegistrySecurity sec = reg.GetAccessControl Dim ar As RegistryAccessRule Dim sid As SecurityIdentifier sid = New SecurityIdentifier(WellKnownSidType.LocalServiceSid, Nothing) ar = New RegistryAccessRule(sid, RegistryRights.ReadKey Or RegistryRights.EnumerateSubKeys Or RegistryRights.QueryValues, AccessControlType.Allow) sec.AddAccessRule(ar) ar = New RegistryAccessRule(sid, RegistryRights.ReadKey Or RegistryRights.EnumerateSubKeys Or RegistryRights.QueryValues, _ InheritanceFlags.ObjectInherit Or InheritanceFlags.ContainerInherit, PropagationFlags.InheritOnly Or PropagationFlags.NoPropagateInherit, AccessControlType.Allow) sec.AddAccessRule(ar) reg.SetAccessControl(sec) End Using End Sub

    I am trying to set a value through reflection. I created this little test program struct headerIndexes { public int AccountNum{ get; set; } public int other { get; set; } public int items { get; set; } } static void Main(string[] args) { headerIndexes headers = new headerIndexes(); headers.AccountNum = 1; Console.WriteLine("Old val: {0}", headers.AccountNum); foreach (var s in headers.GetType().GetProperties()) { if (s.Name == "AccountNum") s.SetValue(headers, 99, null); } Console.WriteLine("New val: {0}", headers.AccountNum); Console.ReadKey(); } Steping thorugh the program i see it correctly does the command s.SetValue(headers, 99, null); however the value of headers.AccountNum stays at 1 when setValue is run. Am I missing a obvious step?

  • Computing orientation of a square and displaying an object with the same orientation

    - by Robin
    Hi, I wrote an application which detects a square within an image. To give you a good understanding of how such an image containing such a square, in this case a marker, could look like: What I get, after the detection, are the coordinates of the four corners of my marker. Now I don't know how to display an object on my marker. The object should have the same rotation/angle/direction as the marker. Are there any papers on how to achieve that, any algorithms that I can use that proofed to be pretty solid/working? It doesn't need to be a working solution, it could be a simple description on how to achieve that or something similar. If you point me at a library or something, it should work under linux, windows is not needed but would be great in case I need to port the application at some point. I already looked at the ARToolkit but they you camera parameter files and more complex matrices while I only got the four corner points and a single image instead of a whole video / camera stream.

  • Keep an object for the time the connection is running in ASP.NET

    - by vtortola
    Hi, I'm developing a web service with ASP.NET, is not an .asmx or WCF, it's a custom one, so I'm working with the Http classes (context, request, response, etc..). Session is disabled. I'm working with my own handler and module. I'd like to keep a object alive and accessible for the time the connection is alive. I mean, a request enters, I assign a DbCommand to it and that connection will use that command as long is doing things, when that connection is ended, the object should be disposed. I've thought, that I can add it to my IPrincipal implementation, then when the connection is authenticated in the module and the user retrieved, I can add that DbCommand to the IPrincipal, so I can retrieve it from wherever I want in the code, and after in the module EndRequest event, I can dispose it, but I don't know if there is a better approach to do this. What do you think? cheers

  • Binding a slider value on the height of its thumb in WPF

    - by sofri
    Hi, I have a databinding problem in WPF. I would like to "customise" a slider in a way that the thumb grows when you move the slider to the right and the thumb shrinks when you move the slider to the left. So I edited the template for the slider and changed the look of the slider so the slider looks like I want it to. But now I have to bind the height of the thumb to the value of the slider but I do not know how that works. I did some simple data binding things but I cannot figure out how I can bind this "thumb height" that's inside of my slider's template to the slider's value that's inside the User Control where my slider is in. So how can I do it?
