  • Delete record in Linq to Sql

    - by Anders Svensson
    I have Linq2Sql classes User, Page, and UserPage (from a junction table), i.e. a many-to-many relationship. I'm using a gridview to show all Users, with a dropdownlist in each row to show the Pages visited by each user. Now I want to be able to delete records through the gridview, so I have added a delete button in the gridview by setting "Enable deleting" on it. Then I tried to use the RowDeleting event to specify how to delete the records since it doesn't work by default. And because its a relationship I know I need to delete the related records in the junction table before deleting the user record itself, so I added this in the RowDeleting event: protected void GridView2_RowDeleting(object sender, GridViewDeleteEventArgs e) { int id = (int)((DataKey)GridView2.DataKeys[e.RowIndex]).Value; UserPageDBDataContext context = new UserPageDBDataContext(); var userPages = from userPage in context.UserPages where userPage.User.UserID == id select userPage; foreach (var userPage in userPages) context.UserPages.DeleteOnSubmit(userPage); context.SubmitChanges(); var user = context.Users.Single(u => u.UserID == id); context.Users.DeleteOnSubmit(user); context.SubmitChanges(); } This actually seems to delete records, because the record with the id in question does indeed disappear, but strangely, a new record seems to be added at the end...! So, say I have 3 records in the gridview: 1 Jack stackoverflow.com 2 Betty stackoverflow.com/questions 3 Joe stackoverflow.com/whatever Now, if I try to delete user 1 (Jack), record number 1 will indeed disappear in the gridview, but the same record will appear at the end with a new id: 2 Jack stackoverflow.com 3 Betty stackoverflow.com/questions 4 Joe stackoverflow.com/whatever I have tried searching on how to delete records using Linq, and I believe I'm doing exacly as the examples I have read (e.g. the second example here: http://msdn.microsoft.com/en-us/library/Bb386925%28v=VS.100%29.aspx). I have read that you can also set cascade delete on the relationship in the database, but I wanted to do it this way in code, as your supposed to be able to. So what am I doing wrong?

  • Exporting non-public type through public API

    - by feelgood
    What if I have few factory methods returning non-public type and pairing set of methods which gives variables of this non-public type? This results with titled warning message in NetBeans. In result public API will contain only two pairing sets of methods. The reason is to make my type hierarchy sealed (like seald classes in Scala) and allow users only instantiate these types through factory methods. So we get DSL in some sense. For example, Schedule class represented by calendar fields' contraints. There are some types of contraints - Range, Singleton, List, FullSet - with NumberSet interface as a root. We don't want to expose these types and how Schedule interact with them. We just want the specification from the user. So we make NumberSet package-private. In class Schedule we create few factory-methods for constraints: NumberSet singleton(int value); NumberSet range(int form, int to); NumberSet list(NumberSet ... components); and some methods for creating Schedule object: Schedule everyHour(NumberSet minutes); Schedule everyDay(NumberSet minutes, NumberSet hours); User can only use them in the manner: Schedule s = Schedule.everyDay( singleton(0), list(range(10-15), singleton(8)) ); Is it bad idea?

  • maven dependencies and jetty - avoiding deploy

    - by James Cooper
    Hi, I have a project with 3 artifacts: common - entities, business logic. no UI code webapp-a - a public web app webapp-b - an admin web app webapp-a and webapp-b depend on common. common is configured to deploy to a local maven repo. so far so good. I have IntelliJ configured so that each artifact is a separate module. Module dependencies are configured properly. I can add a new method to a class in common and immediately use that method in a class in a webapp. However, when I run mvn jetty:run it uses the currently deployed common snapshot in my repository. It does not use my local classes. If I add a method to a class in common, it compiles fine, but blows up at runtime. So is it possible to either: a) Convince jetty:run to use my local common build output or b) Deploy my common output to my local ~/.m2/repo while I'm testing locally before I want to commit/deploy or c) some other solution? thank you! -- James

  • Use Google Calendar UI but showing only filtered events

    - by Edwin
    I have just started using Google Calendar API (using Python client). I'm basically developing a web app for a school with Django. What I'd like to achieve is something like this: To make things simple for now, I have 1 Google account and all events will be created in the calendar under that account (this is the school calendar). The calendar will be made public. When a class is created by a teacher, the class schedule will be automatically added as an event in the Google Calendar. When a student logs in, he can see the school calendar, showing only schedules from the classes that he's registered in. I think I can filter the calendar feeds to show only class schedules that a student is registered in using Google Data API. The problem is, how can I display Google Calendar on my web app using Google Calendar UI to show only those filtered events? I can use Google Calendar UI with the provided embeddable HTML snippet, but I can't control/filter events with that (i.e. all events in the school calendar will be displayed). Or perhaps I'm missing something? I read the Data API guide and the Publishing tool doc but I can't seem to find this information. THanks in advance!

  • Running custom JAXB2 plugins using Maven JAXB 2.x Plugin

    - by nadouani
    I would like to generate JAXB Java classes using the Maven JAXB 2.x plugin http://static.highsource.org/mjiip/maven-jaxb2-plugin/generate-mojo.html To declare the custom JAXB plugins I would execute during the generate process, I used the "args" element like below: <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <version>0.7.4</version> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <extension>true</extension> <args> <arg>-Xinheritance</arg> <arg>-XtoString</arg> </args> ... </configuration> ... </plugin> The issue is that the maven generate process is failing with the following error: Failed to execute goal org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.7.4:generate (default) on project was: Error parsing the command line [[Ljava.lang.String;@1ad4a1ae] Any idea on how to specify the args values?

  • Specifying ASP.NET MVC attributes for auto-generated data models

    - by Lyubomyr Shaydariv
    Hello to everyone. I'm very new to ASP.NET MVC (as well as ASP.NET in general), and going to gain some knowledge for this technology, so I'm sorry I can ask some trivial questions. I have installed ASP.NET MVC 3 RC1 and I'm trying to do the following. Let's consider that I have a model that's completely auto-generated from a table using the "LINQ to SQL Classes" template in VS2010. The template generates 3 files (two .cs files and one .layout file respectively), and the generated partial class is expected to be used as an MVC model. Let's also consider, a single DB column, that's mapped into the model, may look like this: [global::System.Data.Linq.Mapping.ColumnAttribute(Storage = "_Name", DbType = "VarChar(128)")] public string Name { get { return this._Name; } set { if ( (this._Name != value) ) { // ... generated stuff goes here } } } The ASP.NET MVC engine also provides a beautiful declarative way to specify some additional stuff, like RequiredAttribute, DisplayNameAttribute and other nice attributes. But since the mapped model is a purely auto-genereated model, I've realized that I should not change the model manually, and specify the fields like: [Required] [DisplayName("Project name")] [StringLength(128)] [global::System.Data.Linq.Mapping.ColumnAttribute(Storage = "_Name", DbType = "VarChar(128)")] public string Name { ... though this approach works perfectly... until I change the model in the DBML-designer removing the ASP.NET MVC attributes automatically. So, how do I specify ASP.NET MVC attributes for the DBML models and their fields safely? Thanks in advance, and Merry Christmas.

  • javascript class calling XMLHttpRequest internally, then handling onreadystatechange

    - by Radu M
    this thing almost works: function myClass(url) { this.source = url; this.rq = null; this.someOtherProperty = "hello"; // open connection to the ajax server this.start = function() { if (window.XMLHttpRequest) { this.rq = new XMLHttpRequest(); if (this.rq.overrideMimeType) this.rq.overrideMimeType("text/xml"); } else this.rq = new ActiveXObject("Microsoft.XMLHTTP"); try { this.rq.onreadystatechange = connectionEvent; this.rq.open("GET", this.source, true); this.rq.send(null); this.state = 1; } catch (err) { // some error handler here } } function connectionEvent() { alert("i'm here"); alert("this doesnt work: " + this.someOtherProperty); } } // myClass so it's nothing more than having the XMLHttpRequest object as a member of my class, instead of globally defined, and invoking it in the traditional way. however, inside my connectionEvent callback function, the meaning of "this" is lost, even though the function itself is scoped inside myClass. i also made sure that the object that i instantiate from myClass is kept alive long enough (declared global in the script). in all the examples of using javascript classes that i saw, "this" was still available inside the inner functions. for me, it is not, even if i take my function outside and make it a myClass.prototype.connectionEvent. what am i doing wrong? thank you.

  • Winform/Program and how to write class 1, class 2, class 3, class 4 in array to linklabels?!!?

    - by JB
    So my program works like this: using winforms, user enters ID number, using an array, based on the right id number, that student information and class schedule outputs in a message box! My question is how to take the 4 classes in the message box/array and write them to the linklabel text in form 2???? My Getschedule class contains the array and is listed below: namespace Eagle_Eye_Class_Finder { public class GetSchedule { IDnumber[] IDnumbers = new IDnumber[3]; public string GetDataFromNumber(string ID) { foreach (IDnumber IDCandidateMatch in IDnumbers) { if (IDCandidateMatch.ID == ID) { StringBuilder myData = new StringBuilder();

  • Netbeans and EOF

    - by sqlnoob
    Hey there, Java, ANTLR and Netbeans newbie here. I have installed a jdk and netbeans. I started a new project on netbeans 6.8 and i have added the antlr-3.2.jar as a library. I also created a lexer and parser class using AntlrWorks. These classes are named ExprParser.java and ExprLexer.java. I copied them into a directory named path-to-netbeans-project/src/parsers. I have a main file: package javaapplication2; import org.antlr.runtime.*; import parsers.*; public class Main { public static void main(String[] args) throws Exception{ ANTLRInputStream input = new ANTLRInputStream(System.in); ExprLexer lexer = new ExprLexer(input); CommonTokenStream tokens = new CommonTokenStream(lexer); ExprParser parser = new ExprParser(tokens); parser.prog(); } } The application builds fine. The book I'm reading says I should run the program and type in some stuff and then press Ctrl+Z (I'm on windows) to send EOF to the console. Problem is that nothing happens when I press Ctrl+z in the netbeans console. When I run from the command line, ctrl+z works fine. This is probably WAY too much information, but I can't figure it out. Sorry. Probably not a good idea to learn 3 new technologies at once.

  • TinyMCE Image Alignment

    - by will.earp.co.uk
    TinyMCE has always been a little difficult to align images. Either the align tag, or adding style="float: left;" has been it solution. Ideally I would just like to add class="left" or class="right" so that I can set the border and margins of the image. Up until now the only way to do this without using the advimage plugin was to insert the image, then select it, the select a style from the style menu. Ideally I should be able to use the align control in the image dialogue to set the alignment class or use the alignment controls on the toolbar when in the main editing window. I have just again started looking at a solution to this, now that IE6 is finally starting to die, I can use CSS attributes in selectors, so IMG[style="float: left;"] {} Works, but I would rather use a class incase there are any other style attributes which will cause the selector to fail. And it doesn't work in IE6, and you know some corporate clients will still be running the bloody thing! So I looked through the TinyMCE documentation and found the formats configuration option, that seems to allow you to specify how tinyMCE applies code for various operations. Here I can add the IMG tag as a selector, and have classes: "left" for the alignleft function. This applies the class correctly when the alignment is selected from the toolbar, but it still writes an inline style when the alignment is selected through the image dialogue. Am I doing something wrong or is there a better way of doing this that will allow my clients to select image alignment from both the image dialogue and the toolbar, whilst applying a class to the image?

  • Using Directives, Namespace and Assembly Reference - all jumbled up with StyleCop!

    - by Jack
    I like to adhere to StyleCop's formatting rules to make code nice and clear, but I've recently had a problem with one of its warnings: All using directives must be placed inside of the namespace. My problem is that I have using directives, an assembly reference (for mocking file deletion), and a namespace to juggle in one of my test classes: using System; using System.IO; using Microsoft.Moles.Framework; using Microsoft.VisualStudio.TestTools.UnitTesting; [assembly: MoledType(typeof(System.IO.File))] namespace MyNamespace { //Some Code } The above allows tests to be run fine - but StyleCop complains about the using directives not being inside the namespace. Putting the usings inside the namespace gives the error that "MoledType" is not recognised. Putting both the usings and the assembly reference inside the namespace gives the error 'assembly' is not a valid attribute location for this declaration. Valid attribute locations for this declaration are 'type'. All attributes in this block will be ignored. It seems I've tried every layout I can but to no avail - either the solution won't build, the mocking won't work or StyleCop complains! Does anyone know a way to set these out so that everything's happy? Or am I going to have to ignore the StyleCop warning in this case?

  • C++ from SpeakHere in iPhone app

    - by niklassaers
    Hi guys, I've made a template app where I've grabbed the recording part of the SpeakHere example and removed the file handling part, but I'm struggeling to get the C++ part of the app working right. As soon as it enters the C++ class, it gets syntax errors. If I don't import the header files from C++ (and then of course don't use the code) into my Objective C classes, all works fine. I cannot see the difference between how I'm doing it and the example is doing it. Can you see the difference? I've posted the entire code here: http://github.com/niklassaers/testFFT The build errors I get are: testFFT/CAStreamBasicDescription.h:91:0 testFFT/CAStreamBasicDescription.h:91: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'CAStreamBasicDescription' testFFT/CAStreamBasicDescription.h:298:0 testFFT/CAStreamBasicDescription.h:298: error: expected '=', ',', ';', 'asm' or '__attribute__' before '<' token testFFT/CAStreamBasicDescription.h:299:0 testFFT/CAStreamBasicDescription.h:299: error: expected '=', ',', ';', 'asm' or '__attribute__' before '==' token testFFT/CAStreamBasicDescription.h:301:0 testFFT/CAStreamBasicDescription.h:301: error: expected '=', ',', ';', 'asm' or '__attribute__' before '!=' token testFFT/CAStreamBasicDescription.h:302:0 testFFT/CAStreamBasicDescription.h:302: error: expected '=', ',', ';', 'asm' or '__attribute__' before '<=' token testFFT/CAStreamBasicDescription.h:303:0 testFFT/CAStreamBasicDescription.h:303: error: expected '=', ',', ';', 'asm' or '__attribute__' before '>=' token testFFT/CAStreamBasicDescription.h:304:0 testFFT/CAStreamBasicDescription.h:304: error: expected '=', ',', ';', 'asm' or '__attribute__' before '>' token testFFT/CAStreamBasicDescription.h:307:0 testFFT/CAStreamBasicDescription.h:307: error: expected ';', ',' or ')' before '&' token testFFT/CAXException.h:65:0 testFFT/CAXException.h:65: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'CAX4CCString' testFFT/CAXException.h:87:0 testFFT/CAXException.h:87: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'CAXException' testFFT/AQRecorder.h:59:0 testFFT/AQRecorder.h:59: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'AQRecorder' testFFT/RecorderLink.h:57:0 testFFT/RecorderLink.h:57: error: expected specifier-qualifier-list before 'AQRecorder' testFFT/RecorderLink.h:62:0 testFFT/RecorderLink.h:62: error: expected specifier-qualifier-list before 'AQRecorder' Any idea what's going on here?

  • Redirection on the last Slideshow-Element with Jquery

    - by Agssl
    Hi, I'm very new to Jquery and want to realize a manual slideshow with a page-redirect on the last "next"-button. I detect the last Slide-Element with CSS-Classes and then I want to add a Class to the next button to declare that it is the last next-button of the whole Slideshow. The half of my Code works :) – If I navigate to the last Slide-Element, Jquery adds the Class "last" to the button and if I click on the button with this Class, I'm redirected to the next page – that's what I want. But if I navigate to the last Slide-Element, then click a few times the "prev"-button and then again the next button, I'm instantly redirected although the Class "last" was removed. Thanks in advance and sorry for my bad english. Here's my Code: $(document).ready(function(){ $("#image_nav a:first").attr('id', 'firstSlide'); $("#image_nav a:last").attr('id', 'lastSlide'); $(".dritte_ebene li:first").attr('id', 'firstNavi'); $(".dritte_ebene li:last").attr('id', 'lastNavi'); //Redirect to the next page $("a").click(function(){ if ($("#lastSlide").hasClass("activeSlide")) { $("#weiter").addClass("last"); $('.slide').cycle('pause'); $(".last").click(function(){ window.location.replace("[+PJN_next+]"); }); } }); //Remove "last" if prev is clicked $('#zurueck').click(function(){ $("#weiter").removeClass("last"); }); });

  • How can I detect message boxes popping up in another process?

    - by Frerich Raabe
    I'd like to execute some code whenever a (any!) message box (as spawned by the MessageBox Function) is shown in another process. I didn't start the process I'm monitoring. I can think of three approaches: Install a global CBT Hook procedure which tells me whenever a window is created on the desktop. Then, check whether the window belongs to the process I'm monitoring and whether the class name is #32770 (which is the class name of dialogs according to the About Window Classes page at the MSDN). This would probably work, but it would pull the DLL which contains the hook procedure into virtually every process on the desktop, and the hook procedure gets called a lot. It smells like a potential perfomance problem. Try to subclass the #32770 system window class (is this possible at all?) and look for WM_CREATE messages in my custom window procedure. Intercept the MessageBox Function API call (even though the remote process is running already!) and call my code from the hook function. So far, I only know that the first idea is feasible, but it seems really inefficient. Can anybody think of a simpler solution than that to this problem?

  • Job Opportunities

    - by James
    I have a few questions about my job opportunities and I appreaciate it if people could give me some feedback on what I should have in front of me. I am graduatating from a University of Wisconsin--La Crosse this December with a degree in CS and a math minor. I have a cumulative GPA of 3.84 and a major GPA of 4.0 right now (though I still have many classes in front of me). I already have a degree from the U of Minnesota (History, 3.69 GPA) and have worked in the business world for 3+ years (working for a small company in the baseball world, doing some computer programming, statistical research, operations work, technical writing, etc.) I know Java and C well, also am comfortable with Perl. I should have a good grasp of SQL by graduation. I am looking to get a nice programming job (and will be open to moving). Anyone have any advice on things I should learn etc? Also, I would like to know what everyone thinks about my chances of landing a decent job (I realize that is subjective). Also, any ideas on salary I should be looking for (say I am working a metropolitan area). Thanks.

  • UIScrollview calling superviews layoutSubviews when scrolling?

I'm pretty sure its the UIScrollview that the table is inheriting from which is actually doing this but wanted to know if there is a way to disable this functionality and if not why is it happening? I don't understand why when you scroll a scrollview it needs its superview to layout its subviews. Code: @implementation CustomView - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { self.clipsToBounds = YES; UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 15.0, 436.0, 132.0) style:UITableViewStylePlain]; tableView.dataSource = self; tableView.delegate = self; tableView.separatorStyle = UITableViewCellSeparatorStyleNone; tableView.backgroundColor = [UIColor clearColor]; tableView.showsVerticalScrollIndicator = NO; tableView.contentInset = UIEdgeInsetsMake(kRowHeight, 0.0, kRowHeight, 0.0); tableView.tag = componentIndex; [self addSubview:tableView]; [tableView release]; } return self; } - (void)layoutSubviews { // This is called everytime I scroll the tableview } @end

  • Mapping issue with multi-field primary keys using hibernate/JPA annotations

    - by Derek Clarkson
    Hi all, I'm stuck with a database which is using multi-field primary keys. I have a situation where I have a master and details table, where the details table's primary key contains fields which are also the foreign key's the the master table. Like this: Master primary key fields: master_pk_1 Details primary key fields: master_pk_1 details_pk_2 details_pk_3 In the Master class we define the hibernate/JPA annotations like this: @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "idGenerator") @Column(name = "master_pk_1") private long masterPk1; @OneToMany(cascade=CascadeType.ALL) @JoinColumn(name = "master_pk_1", referencedColumnName = "master_pk_1") private List<Details> details = new ArrayList<Details>(); And in the details class I have defined the id and back reference like this: @EmbeddedId @AttributeOverrides( { @AttributeOverride( name = "masterPk1", column = @Column(name = "master_pk_1")), @AttributeOverride(name = "detailsPk2", column = @Column(name = "details_pk_2")), @AttributeOverride(name = "detailsPk2", column = @Column(name = "details_pk_2")) }) private DetailsPrimaryKey detailsPrimaryKey = new DetailsPrimaryKey(); @ManyToOne @JoinColumn(name = "master_pk_1", referencedColumnName = "master_pk_1", insertable=false) private Master master; The goal of all of this was that I could create a new master, add some details to it, and when saved, JPA/Hibernate would generate the new id for master in the masterPk1 field, and automatically pass it down to the details records, storing it in the matching masterPk1 field in the DetailsPrimaryKey class. At least that's what the documentation I've been looking at implies. What actually happens is that hibernate appears to corectly create and update the records in the database, but not pass the key to the details classes in memory. Instead I have to manually set it myself. I also found that without the insertable=true added to the back reference to master, that hibernate would create sql that had the master_pk_1 field listed twice in the insert statement, resulting in the database throwing an exception. My question is simply is this arrangement of annotations correct? or is there a better way of doing it?

  • Input validation in WPF

    - by irfanali-wpfexpert
    i am developing an application in wpf using MVVM design pattern. i have a listbox when an item is slected then a dialog is open having the same record in editable mode. this dialog is binded with the selected item of the list. i have apply the validation rule for textbox using IDataErrorInfo. when the user update a record on dialogbox then at every key press, the selected record in listbox is also changed. if the user press save button then i submit changes to database. but if user click cancel button then i do not submit changes to database but the list box is updated with the current updation in GUI. when i refresh the list then old value appears again. My requirement is to update the listbox only when the user hit the save button but not on every key press on dialog box. I first fill the generic list with the linq to sql classes then bind the listbox with it. Please let me know what i have to do. Thanks in advance

  • I do I iterate the records in a database using LINQ when I have already built the LINQ DB code?

    - by Seth Spearman
    I asked on SO a few days ago what was the simplest quickest way to build a wrapper around a recently completed database. I took the advice and used sqlmetal to build linq classes around my database design. Now I am having two problems. One, I don't know LINQ. And, two, I have been shocked to realize how hard it is to learn. I have a book on LINQ (Linq In Action by Manning) and it has helped some but at the end of the day it is going to take me a couple of weeks to get traction and I need to make some progress on my project today. So, I am looking for some help getting started. Click HERE To see my simple database schema. Click HERE to see the vb class that was generated for the schema. My needs are simple. I have a console app. The main table is the SupplyModel table. Most of the other tables are child tables of the SupplyModel table. I want to iterate through each of Supply Model records. I want to grab the data for a supply model and then DoStuff with the data. And I also need to iterate through the child records, for each supply model, for example the NumberedInventories and DoStuff with that as well. I want to only iterate the SupplyModels that are have IDs that are in an array of strings containing the IDs. I need help doing this in VB rather than C# if possible. Thanks for your help. Seth

  • FIlling a Java Bean tree structure from a csv flat file

    - by Clem
    Hi, I'm currently trying to construct a list of bean classes in Java from a flat description file formatted in csv. Concretely : Here is the structure of the csv file : MES_ID;GRP_PARENT_ID;GRP_ID;ATTR_ID M1 ; ;G1 ;A1 M1 ; ;G1 ;A2 M1 ;G1 ;G2 ;A3 M1 ;G1 ;G2 ;A4 M1 ;G2 ;G3 ;A5 M1 ; ;G4 ;A6 M1 ; ;G4 ;A7 M1 ; ;G4 ;A8 M2 ; ;G1 ;A1 M2 ; ;G1 ;A2 M2 ; ;G2 ;A3 M2 ; ;G2 ;A4 It corresponds to the hierarchical data structure : M1 ---G1 ------A1 ------A2 ------G2 ---------A3 ---------A4 ---------G3 ------------A5 ------G4 ---------A7 ---------A8 M2 ---G1 ------A1 ------A2 ---G2 ------A3 ------A4 Remarks : A message M can have an infinite number of groups G and attributes A A group G can have an infinite number of attributes and an infinite number of under-groups each of them having under-groups too That beeing said, I'm trying to read this flat csv decription to store it in this structure of beans : Map<String, MBean> messages = new HashMap<String, Mbean>(); == public class MBean { private String mes_id; private Map<String, GBean> groups; } public class GBean { private String grp_id; private Map<String, ABean> attributes; private Map<String, GBean> underGroups; } public class ABean { private String attr_id; } Reading the csv file sequentially is ok and I've been investigating how to use recursion to store the description data, but couldn't find a way. Thanks in advance for any of your algorithmic ideas. I hope it will put you in the mood of thinking about this ... I've to admit that I'm out of ideas :s

  • Python: Class factory using user input as class names

    - by Sano98
    Hi everyone, I want to add class atttributes to a superclass dynamically. Furthermore, I want to create classes that inherit from this superclass dynamically, and the name of those subclasses should depend on user input. There is a superclass "Unit", to which I can add attributes at runtime. This already works. def add_attr (cls, name, value): setattr(cls, name, value) class Unit(object): pass class Archer(Unit): pass myArcher = Archer() add_attr(Unit, 'strength', 5) print "Strenght ofmyarcher: " + str(myArcher.strength) Archer.strength = 2 print "Strenght ofmyarcher: " + str(myArcher.strength) This leads to the desired output: Strenght ofmyarcher: 5 Strenght ofmyarcher: 2 But now I don't want to predefine the subclass Archer, but I'd rather let the user decide how to call this subclass. I've tried something like this: class Meta(type, subclassname): def __new__(cls, subclassname, bases, dct): return type.__new__(cls, subclassname, Unit, dct) factory = Meta() factory.__new__("Soldier") but no luck. I guess I haven't really understood what new does here. What I want as a result here is class Soldier(Unit): pass being created by the factory. And if I call the factory with the argument "Knight", I'd like a class Knight, subclass of Unit, to be created. Any ideas? Many thanks in advance! Bye -Sano

  • Pros & Cons of Google App Engine

    - by Rishi
    Pros & Cons of Google App Engine [An Updated List 21st Aug 09] Help me Compile a List of all the Advantages & Disadvantages of Building an Application on the Google App Engine Pros: 1) No Need to buy Servers or Server Space (no maintenance). 2) Makes solving the problem of scaling much easier. Cons: 1) Locked into Google App Engine ?? 2)Developers have read-only access to the filesystem on App Engine. 3)App Engine can only execute code called from an HTTP request (except for scheduled background tasks). 4)Users may upload arbitrary Python modules, but only if they are pure-Python; C and Pyrex modules are not supported. 5)App Engine limits the maximum rows returned from an entity get to 1000 rows per Datastore call. 6)Java applications may only use a subset (The JRE Class White List) of the classes from the JRE standard edition. 7)Java applications cannot create new threads. Known Issues!! http://code.google.com/p/googleappengine/issues/list Hard limits Apps per developer - 10 Time per request - 30 sec Files per app - 3,000 HTTP response size - 10 MB Datastore item size - 1 MB Application code size - 150 MB Pro or Con? App Engine's infrastructure removes many of the system administration and development challenges of building applications to scale to millions of hits. Google handles deploying code to a cluster, monitoring, failover, and launching application instances as necessary. While other services let users install and configure nearly any *NIX compatible software, App Engine requires developers to use Python or Java as the programming language and a limited set of APIs. Current APIs allow storing and retrieving data from a BigTable non-relational database; making HTTP requests; sending e-mail; manipulating images; and caching. Most existing Web applications can't run on App Engine without modification, because they require a relational database.

  • Namespaces combined with TFS / Source Control explanation

    - by Christian
    As an ISV company we slowly run into the "structure your code"-issue. We mainly develop using Visual Studio 2008 and 2010 RC. Languages c# and vb.net. We have our own Team Foundation Server and of course we use Source Control. When we started developing based on the .NET Framework, we also begun using Namespaces in a primitive way. With the time we 'became more mature', i mean we learned to use the namespaces and we structured the code more and more, but only in the solution scope. Now we have about 100 different projects and solutions in our Source Safe. We realized that many of our own classes are coded very redundant, i mean, a Write2Log, GetExtensionFromFilename or similar Function can be found between one and 20 times in all these projects and solutions. So my idea is: Creating one single kind of root folder in Source Control and start an own namespace-hierarchy-structure below this root, let's name it CompanyName. A Write2Log class would then be found in CompanyName.System.Logging. Whenever we create a new solution or project and we need a log function, we will 'namespace' that solution and place it accordingly somewhere below the CompanyName root folder. To have the logging functionality we then import (add) the existing project to the solution. Those 20+ projects/solutions with the write2log class can then be maintained in one single place. To my questions: - is that a good idea, the philosophy of namespaces and source control? - There must be a good book explaining the Namespaces combined with Source Control, yes? any hints/directions/tips? - how do you manage your 50+ projects?
