  • XSLT Type Checking

    - by mo
    Hi Folks Is it possible to check an elements ComplexType? i have this (simplified): complexType Record complexType Customer extension of Record complexType Person extension of Record <xsl:template match="/"> <records> <xsl:apply-templates /> </records> </xsl:template> <xsl:template match="!!! TYPECHECK FOR RECORD !!!" name="Record"> <record><xsl:value-of select="." /></record> </xsl:template> is it possible to check elementstype incl. inheritence? i dont know the elements name only that they are a subtype of Record. schema 1: complexType name="Customer" extension base="Record" element name="customers" element name="customer" type="Customer" schema 2: complexType name="Person" extension base="Record" element name="persons" element name="person" type="Person" schema ?: complexType name="UnknownType" extension base="Record" element name="unknowns" element name="unknown" type="UnknownType" xml 1: <customers> <customer /> <customer /> </customers> xml 2: <persons> <person /> <person /> </persons> xml ?: <?s> <? /> <? /> </?s> the xml input ist custom so i have to match by the type (i think)

  • ipv6 port 445 does not accept the request from a global type address

    - by blacktea
    I want to scan the port 445 in windows server 2003, but my scanner only have one type ipv6 address which is global not link-local. When I do this,I find that I can't find port 445 open. But I use the command "netstat -an" to assure the port 445 is listening. Finally I find this confusing phenomenon: 1.when I set a link-local ddress in my scanner, then it will work in scanning port 445. 2.when I only set a global address in my scanner, it doed not work. This means if a host with a link-local address use socket to send a syn packet to the port 445 in server 2003, it will receive a ack packet. But if with a global address it will receive a rst packet. Thus, I can't scan the port 445 in server 2003 with a global address. I need to know why? Can anybody help? And I use the netsh-firewall to check the exception and netsh-interface-ipv6 to turn off the firewall on the specific interface. Still can't establish the connection with port 445, do you have any ideal about this ?

  • VIM with iA Writer type formatting?

    - by Ambidex
    I've been Googling for a while now. I would like to have iA Writer-like (or a bit like StackExchange) formatting in Vim. Since I love the way it formats my texts, but I'm constantly pressing "w" to skip words because my experience with Vim. I would love to be able to have the same smart formatting in Vim. I did found a nice Vim plugin for getting Vim to toggle to big and clean font: https://github.com/honza/writer.vim But this still does not enable me to use the formatting: # Header 1 ## Header 2 *underline* **strong** etc... Besides all this above, I would not mind to have Vim like shortcuts in my iA writer app if it would not be possible to implement iA formatting in Vim. Edit: After a while of even more searching, I found out this type of formatting is called Markdown. I am starting to think there isn't really a good way to directly edit a Markdown file in Vim, because Vim is not able to make things display like that? I would really like to be able to use the movement shortcuts in combination of the nice formatting of Markdown and how it is displayed in iA Writer.

  • Saving a file in a CSV type in Excel always removes the BOM

    - by rickp
    I've been trying to find a reasonable solution/explanation (unsuccessfully) to find out why Excel defaults to removing the BOM when saving a file to the CSV type. Please forgive me if you find this a duplicate of this question. This handles reading CSV files with non-ASCII encoding, but it doesn't cover saving the file back out (which is where the biggest issue lies). Here is my current situation (which I'm going to gather is common among localized software dealing with Unicode characters and a CSV format): We export data to a CSV format using UTF-16LE, ensuring the BOM is set (0xFFFE). We validate after the file is generated with a Hex editor to ensure it was set correctly. Open the file in Excel (for this example we're exporting Japanese characters) and witness that Excel handles loading the file with the correct encoding. Attempts to save this file will prompt you with a warning message indicating that the file may contain features that may not be compatible with Unicode encoding, but asks if you'd like to save anyway. If you select the Save As dialog, it will immediately ask you to save the file as "Unicode Text" rather than CSV. If you select the "CSV" extension and save the file it removes the BOM (obviously along with all the Japanese characters). Why would this happen? Is there a solution to this problem, or is this a known 'bug'/limitation of Excel? Additionally (as a side issue) it appears that Excel, when loading UTF-16LE encoded CSV files, only uses TAB delimiters. Again, is this another known 'bug'/limitation of Excel?

  • Eclipse Indigo freezes on 'Open Type' search

    - by NickGreen
    When I'm trying to search for a Java class with Ctrl-shift-T (Open Type popup), Eclipse freezes when I'm typing 1 character. It usually takes about 8 seconds to 'unfreeze', but sometimes it won't come back at all.. When it freezes, I see that the eclipse process takes about 1Gig of mem and the CPU is about 100%! I've tried creating a new workspace, adjusting the eclipse.ini (perm size, different memory values), starting with -clean and at last reinstall the whole IDE. Nothing helps.. My eclipse.ini: -startup plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar --launcher.library plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.100.v20110505 -product org.eclipse.epp.package.jee.product --launcher.defaultAction openFile -showsplash org.eclipse.platform --launcher.XXMaxPermSize 768m --launcher.defaultAction openFile -vmargs -server -Dosgi.requiredJavaVersion=1.5 -Xmn128m -Xms1024m -Xmx1024m -Xss2m -XX:PermSize=128m -XX:MaxPermSize=128m -XX:+UseParallelGC -Djava.library.path=/usr/lib/jni I'm using the following plugins: JRebel and m2e. I'm desperate for a solution because this problems causes me a great deal of time loss. System: Ubuntu 12.04 LTS 64 bit, 4GB mem, Intel core i7 860 @ 2.8 Ghz. Hope somebody knows a solution. Thank you for your time.

  • What does SQL Server's BACKUPIO wait type mean?

    - by solublefish
    I'm using Sql Server 2008 ("R1"), with some maintenance plans that back up my databases to a network share. Some of my backup jobs show long waits of type "BACKUPIO". Of course it seems like this is an I/O subsystem limitation, but I'm skeptical. Perfmon stats for I/O on the production (source) server are well within normal trends for that server. The destination server shows a sustained 7MB/s write rate, which seems incredibly low, even for a slow disk. The network link is gigabit ethernet and nowhere near saturated. The few docs I've turned up about BACKUPIO indicate that it's not specifically a wait on I/O, surprisingly enough. This MSFT doc says it's abnormal unless you're using a tape drive, which I'm not. But it doesn't say (or I don't understand) exactly what resource is missing. http://www.docstoc.com/docs/24580659/Performance-Tuning-in-SQL-Server-2005 And this piece says it's not related to I/O performance at all. http://www.informit.com/articles/article.aspx?p=686168&seqNum=5 "Note that BACKUPIO and IO_AUDIT_MUTEX are not related to IO performance." Anyway, does anyone know what BACKUPIO actually means and/or what I can do to diagnose or eliminate it?

  • Questions for anyone who has used Sun Type 7 keyboards

    - by Irinotecan
    So I noticed that Oracle is still selling Sun Type 7 keyboard and mouse packages. I was thinking of buying one for a Linux box at my house so I had easy access to some of the extra keys such as Compose and Alt-GR. I have some questions though before I do for anyone who has used these -- it's been a very long time since I've used an actual Sun keyboard. They show that both a PC and UNIX layout is available. Unfortunately, I cannot find anywhere a clear picture of both layouts to determine the difference. Can anyone post pictures of the 2 different layouts for me to take a look at? I don't remember what some of the "Solaris shortcut" keys do, like Props, Front, Stop, and Again. Are these vestiges from OpenWindows? Do they have any usage on a modern Solaris like OpenSolaris running Gnome? Do they automatically map to anything useful on Linux, or am I going to have to map them myself to something with XModMap? When I last used a Sun keyboard, I remember it having a rather mushy feel to it, so I am wondering if any touch typists could weigh in on whether this keyboard "feels nice" for day to day touch typing. Thanks!

  • Broken corba object references

    - by cube
    I'm working on a homework and got stuck. The task is to serve objects using a default servant. But when I try to use the reference, weird things happen. Some part of corba prints a stack trace, but no exception is thrown. The problem happens when the server receives the reference and should call some method on it. The reference is then shortened and doesn't contain the object ID (which means that my servant implementation can't do anything reasonable). This is the implementation of the servant, where the problem appears: public class ModelFileImpl extends ModelFilePOA{ @Override public String getName() { try { return new String(_poa().reference_to_id(_this_object())); } catch (Throwable e) {} assert false; return null; } } If I take _this_object().toString() inside the try block and put it into dior -i i get this: ------IOR components----- TypeId : IDL:termproject/idl/ModelFile:1.0 TAG_INTERNET_IOP Profiles: Profile Id: 0 IIOP Version: 1.2 Host: 127.0.0.1 Port: 45954 Object key (URL): %AF%AB%CB%00%00%00%00%20Q%BA%F4%FF%00%00%00%01%00%00%00%00%00%00%00%01%0000%00%08RootPOA%00%00%00%00%08%00%00%00%02%00%00%00%00%14 Object key (hex): 0xAF AB CB 00 00 00 00 20 51 BA F4 FF 00 00 00 01 00 00 00 00 00 00 00 01 00 00 00 08 52 6F 6F 74 50 4F 41 00 00 00 00 08 00 00 00 02 00 00 00 00 14 -- Found 2 Tagged Components-- #0: TAG_CODE_SETS ForChar native code set Id: ISO8859_1 Char Conversion Code Sets: UTF8 , Unknown TCS: 10020 ForWChar native code set Id: UTF16 WChar Conversion Code Sets: Unknown TCS: 10100 Unknown tag : 38 however the part of server that makes the reference and the client see the reference as ------IOR components----- TypeId : IDL:termproject/idl/ModelFile:1.0 TAG_INTERNET_IOP Profiles: Profile Id: 0 IIOP Version: 1.2 Host: 127.0.0.1 Port: 45954 Object key (URL): %AF%AB%CB%00%00%00%00%20Q%BA%F4%FF%00%00%00%01%00%00%00%00%00%00%00%02%00%00%00%08RootPOA%00%00%00%00%09modelPoa%00%00%00%00%00%00%00%10testModel1.MyIDL%14 Object key (hex): 0xAF AB CB 00 00 00 00 20 51 BA F4 FF 00 00 00 01 00 00 00 00 00 00 00 02 00 00 00 08 52 6F 6F 74 50 4F 41 00 00 00 00 09 6D 6F 64 65 6C 50 6F 61 00 00 00 00 00 00 00 10 74 65 73 74 4D 6F 64 65 6C 31 2E 4D 79 49 44 4C 14 -- Found 2 Tagged Components-- #0: TAG_CODE_SETS ForChar native code set Id: ISO8859_1 Char Conversion Code Sets: UTF8 , Unknown TCS: 10020 ForWChar native code set Id: UTF16 WChar Conversion Code Sets: Unknown TCS: 10100 Unknown tag : 38 ("modelPoa" (the name of the poa working with default clients) and "testModel1.MyIDL" (the identifier of the object) in the object key are missing in the first one) I've tried sniffing the traffic and found out that the client still sends the correct reference.

Policy[] policies = { poa.create_request_processing_policy(RequestProcessingPolicyValue.USE_DEFAULT_SERVANT), poa.create_servant_retention_policy(ServantRetentionPolicyValue.NON_RETAIN), poa.create_id_assignment_policy(IdAssignmentPolicyValue.USER_ID) }; POA modelPoa = poa.create_POA("modelPoa", poa.the_POAManager(), policies); modelPoa.the_POAManager().activate(); modelPoa.set_servant(new ModelFileImpl()); modelPoa.the_POAManager().activate(); ModelStoreImpl impl = new ModelStoreImpl(modelPoa); // create the object reference org.omg.CORBA.Object obj = poa.servant_to_reference(impl); // ... store the IOR file ... orb.run(); I'd be really grateful for any pointers (or references :-) )

  • Programmatically adding an object and selecting the correspondig row does not make it become the CurrentRow

    - by Robert
    I'm in a struggle with the DataGridView: I do have a BindingList of some simple objects that implement INotifyPropertyChanged. The DataGridView's datasource is set to this BindingList. Now I need to add an object to the list by hitting the "+" key. When an object is added, it should appear as a new row and it shall become the current row. As the CurrentRow-property is readonly, I iterate through all rows, check if its bound item is the newly created object, and if it is, I set this row to "Selected = true;" The problem: although the new object and thereby a new row gets inserted and selected in the DataGridView, it still is not the CurrentRow! It does not become the CurrentRow unless I do a mouse click into this new row. In this test program you can add new objects (and thereby rows) with the "+" key, and with the "i" key the data-bound object of the CurrentRow is shown in a MessageBox. How can I make a newly added object become the CurrentObject? Thanks for your help! Here's the sample: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { BindingList<item> myItems; public Form1() { InitializeComponent(); myItems = new BindingList<item>(); for (int i = 1; i <= 10; i++) { myItems.Add(new item(i)); } dataGridView1.DataSource = myItems; } public void Form1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Add) { addItem(); } } public void addItem() { item i = new item(myItems.Count + 1); myItems.Add(i); foreach (DataGridViewRow dr in dataGridView1.Rows) { if (dr.DataBoundItem == i) { dr.Selected = true; } } } private void btAdd_Click(object sender, EventArgs e) { addItem(); } private void dataGridView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Add) { addItem(); } if (e.KeyCode == Keys.I) { MessageBox.Show(((item)dataGridView1.CurrentRow.DataBoundItem).title); } } } public class item : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; private int _id; public int id { get { return _id; } set { this.title = "This is item number " + value.ToString(); _id = value; InvokePropertyChanged(new PropertyChangedEventArgs("id")); } } private string _title; public string title { get { return _title; } set { _title = value; InvokePropertyChanged(new PropertyChangedEventArgs("title")); } } public item(int id) { this.id = id; } #region Implementation of INotifyPropertyChanged public void InvokePropertyChanged(PropertyChangedEventArgs e) { PropertyChangedEventHandler handler = PropertyChanged; if (handler != null) handler(this, e); } #endregion } }

  • How can I get the camera to follow a moving object from behind in C++ and openGL [closed]

    - by user1324894
    I am trying to get the camera to follow an object that moves around my environment using the gluLookAt function. This is my code for the object moving in the direction that it faces: Xtri += -Vtri*cos((90+heading)*(PI/180.0f)); Ztri += Vtri*sin((90+heading)*(PI/180.0f)); I then render the object: glPushMatrix(); glTranslatef(Xtri,0,Ztri); glRotatef(heading,0,1,0); drawTriangle(); glPopMatrix(); All heading is is a spin variable so that if I press left or right it spins in that direction. When you press up on the arrows it moves forward and if you press down it moves backwards in the direction that it is facing. To try and get it so the camera follows I am using the gluLookAt function like this: gluLookAt(Xtri,0,(Ztri+20), Xtri,0,Ztri, 0,1,0); So that it follows the car from a distance and should follow it around. However, the object doesn't even move at all now all it can do is rotate still but not move forwards or backwards and when it spins it doesn't follow the spin instead it just watches it turn still fixed to the same position. Where is it that I am going wrong? UPDATE: I have updated the gluLookAt function so now it is: gluLookAt((Xtri+Vtri),0,((Ztri+20)), (Xtri+Vtri),0,(Ztri), 0,1,0); This seems to move the object around. I have a stationary terrain so I can see that the object is now moving and in the direction that it is facing. However, I want the camera to follow the object when it spins as well so it is always viewing the object from behind.

  • Refactoring an ERB Template to Haml

    - by Liam McLennan
    ERB is the default view templating system used by Ruby on Rails. Haml is an alternative templating system that uses whitespace to represent document structure. The example from the haml website shows the following equivalent markup: Haml ERB #profile .left.column #date= print_date #address= current_user.address .right.column #email= current_user.email #bio= current_user.bio <div id="profile"> <div class="left column"> <div id="date"><%= print_date %></div> <div id="address"><%= current_user.address %></div> </div> <div class="right column"> <div id="email"><%= current_user.email %></div> <div id="bio"><%= current_user.bio %></div> </div> </div> I like haml because it is concise and the significant whitespace makes it easy to see the structure at a glance. This post is about a ruby project but nhaml makes haml available for asp.net MVC also. The ERB Template Today I spent some time refactoring an ERB template to Haml. The template is called list.html.erb and its purpose is to render a list of tweets (twitter messages). <style> form { float: left; } </style> <h1>Tweets</h1> <table> <thead><tr><th></th><th>System</th><th>Human</th><th></th></tr></thead> <% @tweets.each do |tweet| %> <tr> <td><%= h(tweet['text']) %></td> <td><%= h(tweet['system_classification']) %></td> <td><%= h(tweet['human_classification']) %></td> <td><form action="/tweet/rate" method="post"> <%= token_tag %> <input type="submit" value="Positive"/> <input type="hidden" value="<%= tweet['id']%>" name="id" /> <input type="hidden" value="positive" name="rating" /> </form> <form action="/tweet/rate" method="post"> <%= token_tag %> <input type="submit" value="Neutral"/> <input type="hidden" value="<%= tweet['id']%>" name="id" /> <input type="hidden" value="neutral" name="rating" /> </form> <form action="/tweet/rate" method="post"> <%= token_tag %> <input type="submit" value="Negative"/> <input type="hidden" value="<%= tweet['id']%>" name="id" /> <input type="hidden" value="negative" name="rating" /> </form> </td> </tr> <% end %> </table> Haml Template: Take 1 My first step was to convert this page to a Haml template in place. Directly translating the ERB template to Haml resulted in: list.haml %style form {float: left;} %h1 Tweets %table %thead %tr %th %th System %th Human %th %tbody - @tweets.each do |tweet| %tr %td= tweet['text'] %td= tweet['system_classification'] %td= tweet['human_classification'] %td %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Positive"/> <input type="hidden" value="positive" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Neutral"/> <input type="hidden" value="neutral" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Negative"/> <input type="hidden" value="negative" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} end I like this better already but I can go further. Haml Template: Take 2 The haml documentation says to avoid using iterators so I introduced a partial template (_tweet.haml) as the template to render a single tweet. _tweet.haml %tr %td= tweet['text'] %td= tweet['system_classification'] %td= tweet['human_classification'] %td %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Positive"/> <input type="hidden" value="positive" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Neutral"/> <input type="hidden" value="neutral" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Negative"/> <input type="hidden" value="negative" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} and the list template is simplified to: list.haml %style form {float: left;} %h1 Tweets %table     %thead         %tr             %th             %th System             %th Human             %th     %tbody         = render(:partial => "tweet", :collection => @tweets) That is definitely an improvement, but then I noticed that _tweet.haml contains three form tags that are nearly identical.   Haml Template: Take 3 My first attempt, later aborted, was to use a helper to remove the duplication. A much better solution is to use another partial.  _rate_button.haml %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag %input{ :type => "submit", :value => rate_button[:rating].capitalize } %input{ :type => "hidden", :value => rate_button[:rating], :name => 'rating' } %input{ :type => "hidden", :value => rate_button[:id], :name => 'id' } and the tweet template is now simpler: _tweet.haml %tr %td= tweet['text'] %td= tweet['system_classification'] %td= tweet['human_classification'] %td = render( :partial => 'rate_button', :object => {:rating=>'positive', :id=> tweet['id']}) = render( :partial => 'rate_button', :object => {:rating=>'neutral', :id=> tweet['id']}) = render( :partial => 'rate_button', :object => {:rating=>'negative', :id=> tweet['id']}) list.haml remains unchanged. Summary I am extremely happy with the switch. No doubt there are further improvements that I can make, but I feel like what I have now is clean and well factored.

  • Bad value for type timestamp on production server

    - by Juan Javaloyes
    I'm working with: seam 2.2.2 + hibernate + richfaces + jboss 5.1 + postgres I have an module which needs to load some data from the database. Easy. The problem is, on development it works fine, 100%, but when I deploy on my production server and try to get the data, an error rise: could not read column value from result set: fechahor9_504_; Bad value for type timestamp : [C@122e5cf SQL Error: 0, SQLState: 22007 Bad value for type timestamp : [C@122e5cf javax.persistence.PersistenceException: org.hibernate.exception.DataException: could not execute query [more errors] Caused by: org.postgresql.util.PSQLException: Bad value for type timestamp : [C@122e5cf at org.postgresql.jdbc2.TimestampUtils.loadCalendar(TimestampUtils.java:232) [more errors] Caused by: java.lang.NumberFormatException: Trailing junk on timestamp: '' at org.postgresql.jdbc2.TimestampUtils.loadCalendar(TimestampUtils.java:226) I can't understand why it works on my machine (development) and why not on production. Any clues? Anyone gone through the same problem? Is exactly the same compilation

  • Windows RT Powershell (PermissionDenied) on New-Object

    - by bazile
    I am trying to instantiate an object in Powershell for Windows RT, but keep getting the following error. PS > $foo = New-Object System.Security.Cryptography.SHA1Managed New-Object : Cannot create type. Only core types are supported in this language mode. At line:1 char:8 + $foo = New-Object System.Security.Cryptography.SHA1Managed + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : PermissionDenied: (:) [New-Object], PSNotSupportedException + FullyQualifiedErrorId : CannotCreateTypeConstrainedLanguage,Microsoft.PowerShell.Commands.NewObjectCommand I just spent the last thirty minutes engaged in some pretty heavy Google-fu and was unable to find anything even close to a similar problem, let alone an answer. My hope is that I just need to configure something; my fear is that Windows RT ships with a crippled version of Powershell. Does anyone know which case it is?

  • How to fix type names conflicts in Dynamic Data

    - by SDReyes
    Hi Guys! We're working in a Dynamic Data project that will handle entities coming from two different namespaces: myModel.Abby and myModel.Ben. whose classes are: Abby myModel.Abby.Car myModel.Abby.Lollipop Ben myModel.Ben.Car myModel.Ben.Apple So myModel.Abby.Car and myModel.Ben.Car are homonym. when I try to register both ObjectContext's, an exception is thrown telling us that there are type name conflicts between the mentioned classes (although the types belong to different namespaces). How can we overcome type-name conflicts, caused by repeated type names among different namespaces?

  • Error when starting ArcGIS Server Object Manager (v10)

    - by SpatialBridge
    I just finished installing ArcGIS Server 10 and completed the post-installation. The ArcGIS Server Object Manager service is installed, but when I try to start it, I get the following error: "Windows could not start the ArcGIS Server Object Manager service on the Local Computer. Error 1067: The process terminated unexpectedly." The agsadmin and agsusers groups exist, and my local account is a member of the agsadmin group. Any ideas on what I've done wrong? Thanks, Jon.

  • linq2sql : get generic type of table

    - by benpage
    i think this is a simple question but I've searched around and can't seem to find an answer easily. if you have var list = List<int>(); ... fill list ... and you want to get the generic type in list, i realise you could just type: var t = list.FirstOrDefault().GetType(); Is there another way to do this via just the list, rather than referring to the enumeration? Reason is, i have a System.Data.Linq.Table<TABLE1> and what i want to do is get the type of TABLE1 from it. so: var table = new DataContext().TABLE1s; // this is Table<TABLE1> var tableType = table.GetType().SomeMethod(); // i want tableType to equal TABLE1.GetType()

  • Set attributes from dictionary in python

    - by Oscar Reyes
    Is it possible to create an object from a dictionary in python in such a way that each key is an attribute of that object? Something like this: dict = { 'name': 'Oscar', 'lastName': 'Reyes', 'age':32 } e = Employee( dict ) print e.name # Oscar print e.age + 10 # 42 I think it would be pretty much the inverse of this question: Python dictionary from an object's fields

  • C# Lack of Static Inheritance - What Should I Do?

    - by yellowblood
    Alright, so as you probably know, static inheritance is impossible in C#. I understand that, however I'm stuck with the development of my program. I will try to make it as simple as possible. Lets say our code needs to manage objects that are presenting aircrafts in some airport. The requirements are as follows: There are members and methods that are shared for all aircrafts There are many types of aircrafts, each type may have its own extra methods and members. There can be many instances for each aircraft type. Every aircraft type must have a friendly name for this type, and more details about this type. For example a class named F16 will have a static member FriendlyName with the value of "Lockheed Martin F-16 Fighting Falcon". Other programmers should be able to add more aircrafts, although they must be enforced to create the same static details about the types of the aircrafts. In some GUI, there should be a way to let the user see the list of available types (with the details such as FriendlyName) and add or remove instances of the aircrafts, saved, lets say, to some XML file. So, basically, if I could enforce inherited classes to implement static members and methods, I would enforce the aircraft types to have static members such as FriendlyName. Sadly I cannot do that. So, what would be the best design for this scenario?

  • HttpHandler instance and HttpApplication object - does the latter...?

    - by SourceC
    A Book showed an example where ( when using IIS7 ) the following module was configured such that it would be used by any web application ( even by non-asp.net apps ) running on a web site. But: A) if this module is invoked for non-asp.net application, then how or why would HttpApplication object still be created, since non-asp.net apps don’t run in the context of CLR ( and thus Asp.Net runtime also won’t run )? b) Assuming HttpApplication object is also created for non-asp.net apps, why then does the code inside Init() event handler have to check for whether HttpApplication object actually exists? Why wouldn’t it exist? Isn’t this HttpApplication object which actually instantiates Http module instance? Here is Http handler: public class SimpleSqlLogging : IHttpModule { private HttpApplication _CurrentApplication; public void Dispose() { _CurrentApplication = null; } public void Init(HttpApplication context) { // Attach to the incoming request event _CurrentApplication = context; if (context != null) { context.BeginRequest += new EventHandler(context_BeginRequest); } } void context_BeginRequest(object sender, EventArgs e) { ... } }

  • TypeConverter prevents ApplyPropertyChanges in EntityFramework

    - by Felix
    I ran into an interesting problem (hopefully, interesting not just for me :) I am running Entity Framework 1 (.NET 3.5) and ASP.NET MVC 2. I have a Customer class that has many-to-one relationship with Country class (in other words, Country is a lookup table for customers - I described more in this post: http://stackoverflow.com/questions/2404801/explicit-casting-doesnt-work-in-default-model-binding ) I got TypeConverter to work; so I am getting a perfect object into controller's Post method. Create works fine; however, in Edit I am getting the following error when I call ApplyPropertyChanges: The existing object in the ObjectContext is in the Added state. Changes can only be applied when the existing object is in an unchanged or modified state. The controller code is fairly trivial: public ActionResult Edit(Customer customerToEdit) { if (ModelState.IsValid) { Customer cust = (Customer)context.GetObjectByKey( new EntityKey("BAEntities.Customers", "CustomerID", customerToEdit.CustomerID)); context.ApplyPropertyChanges(cust.EntityKey.EntitySetName, customerToEdit); context.SaveChanges(); } return View(...); } If I remove country from the form, it works fine; and if I assign dropdown value to EntityReference "manually" - it works as well. TypeConverter code is also fairly simple, but I've never used TypeConverter before, so I may be missing something here: public override object ConvertFrom(ITypeDescriptorContext typeContext, CultureInfo culture, object value) { if (value is string) { int countryID = Int16.Parse((string)value); Country country = (Country)context.GetObjectByKey( new EntityKey("BAEntities.Countries", "CountryID", countryID)); return country; } return base.ConvertFrom(typeContext, culture, value); }

  • Control JSON Serialization format of a custom type in .NET

    - by mrjoltcola
    I have a PhoneNumber class that stores a normalized string, and I've defined implicit operators for string <- Phone to simplify treatment of the PhoneNumber as a string. I've also overridden the ToString() method to always return the cleaned version of the number (no hyphens or parentheses or spaces). In any MVC.NET code where I explicitly display the number, I can explicitly call phone.Format(). The problem here is serializing an entity that has a PhoneNumber to JSON; JavaScriptSerializer serializes it as [object Object]. I want to serialize it as a string in (555)555-5555 format. I've looked at writing a custom JavaScriptConverter, but JavaScriptConverter.Serialize() method returns a dictionary of name-value pairs. I don't want PhoneNumber to be treated as an object with fields, I want to simply serialize it as a string.

  • Setting the primary key of a object type table in Oracle

    - by Rek
    I have two Oracle questions. How can I set the primary key of a table when the table is made up of an object type? e.g. CREATE TABLE object_names OF object_type I have created a Varray type, CREATE TYPE MULTI_TAG AS VARRAY(10) OF VARCHAR(10); but when I try to do SELECT p.tags.count FROM pg_photos p; I get an invalid identifier error on the "count" part. p.tags is a MULTI_TAG, how can I get the number of elements in the MULTI_TAG?
