  • How to name an event handler of a private variable in Vb.Net following FxCop rules and Vb.Net standa

    - by SoMoS
    Hello, On one side, in Vb.Net when you add an event handler to an object the created method is named: <NameOfTheObject>_<NameOfTheMethod>. As I like to have consistent syntax I always follow this rule when creating event handlers by hand. On the other side when I create private variables I prefix them with m_ as this is a common thing used by the community, in C# people use to put _ at the beginning of a variable but this is no CLS compliant. At the end, when I create event handlers for events raised by private variables I end with Subs like m_myVariable_MyEvent. Code Analysis (Fx Cop) is complainig about this way of naming because the method does not start with uppercase and because the _, so the question is: What naming standards do you follow when creating event handlers by hand that follow the Fxcop rules if any? Thanks in advance.

  • iphone navigation tutorial with simple form

    - by iamthewit
    Hi All, I'm looking to create quite a basic app with a very simple navigation system but each of the tutorials I've come across so far go into too much depth or just involve lots of different form elements. I want to keep it as straight forward and simple as I can. If anyone knows of any tutorials that can show me how to create a root view with say 5 or 6 sub views each displaying a form for collecting different types of data I would be very grateful. This seems like quite a simple thing to achieve but so far I havent found anything that specifically relates to what I want to do. thanks in advance!

  • Weird problem, with ghostscript and pdf files.

    - by kofucii
    Hello, am using ghostscript to create pdf file from postscript file. My PS file, doesn't have orientation instructions, so when I want to create landscape pdf file, I'm using ghostscript to rotate the page. The problem is, that ghostscript rotates only the first page, and when my pdf file is more than 1 page, the others, are not rotated correctly. Here is the command I'm using: cat $psinput | gs -sPAPERSIZE=a4 -sDEVICE=pdfwrite -sOuputFile="/tmp/pdf" \ -dAutoRotatePages="/None" -c "<< /Orientation 3 >> setpagedevice" \ 90 rotate 0 -595 translate -dNOPAUSE -dEPSCrop -f - -c -quit Does anybody have an idea how to correct this?

  • Error implementing Dynamic Tab with ListView within each Tab - Tabs don't show up

    - by Jon
    I am trying to create a dyanmic tab application that has tabs on the left for each type of Food (e.g. Pasta, Dairy, etc. including those dynamically defined by user) and for each tab, have a listview connected to a SQLite database that updates. This is in the onCreate method: setContentView(R.layout.foodCabinet_layout); dbHelper = new FoodStorageDBHelper(this); dbHelper.open(); Cursor foodTypes = dbHelper.getAllFoodTypes(); ArrayList<String> typeOfFood = new ArrayList<String>(); typeOfFoods.add(foodTypes.getString(1)); while(foodTypes.moveToNext()){ typeOfFoods.add(foodTypes.getString(1)); } final TabHost tbh = (TabHost)findViewById(R.id.food_tabhost_cabinet); tbh.setup(); for(final String s : typeOfFood){ TabSpec nts = tbh.newTabSpec(s); nts.setIndicator(s.replace('_', ' ')); nts.setContent(new TabHost.TabContentFactory(){ public View createTabContent(String tag) { ListView foodCabinetLV = new ListView(FoodCabinet.this); Cursor mCursor = dbHelper.getAllFoodsWithType(s); // Create an array to specify the fields we want to display in the list (only TITLE) String[] from = new String[]{FoodStorageDBHelper.KEY_NAME, FoodStorageDBHelper.KEY_YEAR,FoodStorageDBHelper.KEY_RANK}; // and an array of the fields we want to bind those fields to (in this case just text1) int[] to = new int[]{R.id.childname,R.id.childyear,R.id.childrank}; // Now create a simple cursor adapter and set it to display SimpleCursorAdapter notes = new SimpleCursorAdapter(FoodCabinet.this, R.layout.food_row, mCursor, from, to); foodCabinetLV.setAdapter(notes); startManagingCursor(mCursor); foodCabinetLV.setOnItemClickListener( new AdapterView.OnItemClickListener() { public void onItemClick(AdapterView arg0, View arg1, int arg2, long arg3) { Intent i = new Intent(); i.setClass(arg0.getContext(), EditFoodDialog.class); i.putExtra(FoodStorageDBHelper.KEY_ROWID, Long.toString(arg3)); startActivityForResult(i, LoadFoodOrganizer.ACTIVITY_EDIT); } }); return foodCabinetLV; } }); } For some reason, it doesn't show anything... it's a blank screen. Any help would be very much appreciated. Let me know! Thanks! Jon

  • Why is the C# SerializedAttribute is sealed?

    - by ahmet alp balkan
    I was trying to create an attribute that implies [Serializable] but I noticed that this SerializableAttribute class is sealed. In Java it was possible to create an interface (say, MyInterface) that is inherited from Serializable interface and so all the subclasses of MyInterface would also be serializable, even its sub-sub classes would be so. Let's say I am creating an ORM and I want customers to annotate their entity classes as [DatabaseEntity] but in order to make sure that entities are serializable, I also need to ask them to attribute their classes with extra [Serializable] which does not look quite compact and neat. I am wondering why SerializableAttribute class is sealed and why has Inherited=false which implies that subclasses of serializable class will not be serializable unless it is explicitly stated. What motives are behind these design choices?

  • Using empty row as default in a ComboBox with Style "DropDownList"?

    - by Pesche Helfer
    Hi board I am trying to write a method, that takes a ComboBox, a DataTable and a TextBox as arguments. The purpose of it is to filter the members displayed in the ComboBox according to the TextBox.Text. The DataTable contains the entire list of possible entries that will then be filtered. For filtering, I create a DataView of the DataTable, add a RowFilter and then bind this View to the ComboBox as DataSource. To prevent the user from typing into the ComboBox, I choose the DropDownStyle DropDownList. That’s working fine so far, except that the user should also be able to choose nothing / empty line. In fact, this should be the default member to be displayed (to prevent choosing a wrong member by accident, if the user clicks through the dialog too fast). I tried to solve this problem by adding a new Row to the view. While this works for some cases, the main issue here is that any DataTable can be passed to the method. If the DataTable contains columns that cannot be null and don’t contain a default value, I suppose I will raise an error by adding an empty row. A possibility would be to create a view that contains only the column that is defined as DisplayMember, and the one that is defined as ValueMember. Alas, this can’t be done with a view in C#. I would like to avoid creating a true copy of the DataTable at all cost, since who knows how big it will get with time. Do you have any suggestions how to get around this problem? Instead of a view, could I create an object containing two members and assign the DisplayMember and the ValueMember to these members? Would the members be passed as reference (what I hope) or would true copied be created (in which case it would not be a solution)? Thank you very much for your help! Best regards public static void ComboFilter(ComboBox cb, DataTable dtSource, TextBox filterTextBox) { cb.DropDownStyle = ComboBoxStyle.DropDownList; string displayMember = cb.DisplayMember; DataView filterView = new DataView(dtSource); filterView.AddNew(); filterView.RowFilter = displayMember + " LIKE '%" + filterTextBox.Text + "%'"; cb.DataSource = filterView; }

  • Automatic Hudson CI setup and plugin updates through apt?

    - by aapeli
    Hi! We've used Hudson for quite a while to implement a CI server with all the bells and whistles. The setup is quite straight forward, when installing from the provided RPMs and Debs, but through googling I haven't been able to figure out whether the plugins are installable using apt/rpm or some other package manager? The reason is that I would like to create a (meta)package for Ubuntu which would install and also update both Hudson and all the plugins through the normal upgrade mechanism. At the same time I could create a template setup for other projects, say JavaEE project needs git, cobertura and Chuck Norris plugins, while my Python project needs plugins XXX and YYY. Anybody got such a setup? As a workaround I figured setting up a number of Maven POMs, which would do the init, and later upgrades, but I feel this would require more scripting on the side, which I'm not very eager to do. Any other suggestions for this would also be appreciated.

  • TFS and team project portal question

    - by DotnetDude
    The team explorer for my project looks like this: mytfsserver\mycollection -- Project 1 solution -- Project 2 solution -- Project 3 solution When I right click on one of the solutions and do a "Show Project Portal", I see the following hierarchy: mycollection - WSS site Project 1 site with dashboard (appears to be a MOSS site) Project 2 site with dashboard (appears to be a MOSS site) Project 3 site with dashboard (appears to be a MOSS site) Are the dashboard sites MOSS sites? If I want to create a wiki, do I have to create a subsite with the wiki template under each of the Project sites? Can someone point me to a document/video that talks about the sites that area created by TFS by default?

  • PayPal testing without using Sandbox

    - by Webbo
    I am developing a website in PHP that accepts PayPal payments. It uses the IPN from PayPal and has a custom payment template etc etc. It all works great through the Sandbox server but when it comes to showing my client, I don't want to have to tell them to login to/create a Sandbox account, create a buyer account and make a payment - he hasn't got time for that and probably won't be able to do it. Therefore, my question is - is there any simple way that I can show my client the PayPal integration in "test mode" without him using the sandbox? I realise that I can set the transaction value to 0.01 and just test on the live PayPal server but that isn't an ideal solution. Cheers! Edit: Just to better explain what I mean, this is what my client sees when he first goes to checkout; As you can see, he has to login to his Sandbox account before then purchasing the item using the buyer email that he sets up. It's just confusing and totally non user-friendly.

  • How to count the length (number of lines) of a csv file in Rails?

    - by Mathias
    Hello, I have a form (Rails) which allows me to load a .csv file using the file_field. In the view: <% form_for(:upcsv, :html => {:multipart => true}) do |f| %> <table> <tr> <td><%= f.label("File:") %></td> <td><%= f.file_field(:filename) %></td> </tr> </table> <%= f.submit("Submit") %> <% end %> Clicking Submit redirects me to another page (create.html.erb). The file was loaded fine, and I was able to read the contents just fine in this second page. I am trying to show the number of lines in the .csv file in this second page. My controller (semi-pseudocode): class UpcsvController < ApplicationController def index end def create file = params[:upcsv][:filename] ... #params[:upcsv][:file_length] = file.length # Show number of lines in the file #params[:upcsv][:file_length] = file.size ... end end Both file.length and file.size returns '91' when my file only contains 7 lines. From the Rails documentation that I read, once the Submit button is clicked, Rails creates a temp file of the uploaded file, and the params[:upcsv][:filename] contains the contents of the temp/uploaded file and not the path to the file. And I don't know how to extract the number of lines in my original file. What is the correct way to get the number of lines in the file? My create.html.erb: <table> <tr> <td>File length:</td> <td><%= params[:upcsv][:file_length] %></td> </tr> </table> I'm really new at Rails (just started last week), so please bear with my stupid questions. Thank you!

  • Passing single attributes to associated factories

    - by lambdabutz
    I'm looking for a way to pass fields into the factories of associated models without having to explicitly call the factory itself. For example, lets say I have some factories like so: Factory.define :person do |person| person.name "Default Bob" person.sex "M" person.house {|p| p.association(:house)} end Factory.define :house do |house| house.color "Red" house.has_ac true house.suburb {|h| h.association(:suburb)} end Factory.define :suburb do |suburb| suburb.name "Little boxes" end This is fine and all, but if I want to use factories to create someone in a specific house in a specific suburb I have do this: sub = Factory(:suburb, :name => "Blue town") house = Factory(:house, :color => "Blue", :suburb => sub) person = Factory(:person, :name => "Bill", :house => house) While this isn't bad in this small case, my actual models sometimes have 7 or 8 associations, and when I want to create an object whose associations I only care about a single attribute, the code for this starts to get really heavy. Is there somewhat I can pass attributes to nested Factories without having to recall the Factory itself?

  • Updating D3 column chart with different values and different data sizes

    - by mbeasley
    Background I am attempting to create a reusable chart object with D3.js. I have setup a chart() function that will produce a column chart. On a click event on any of the columns, the chart will update with a new random data array that will contain a random number of data points (i.e. the original chart could have 8 columns, but upon update, could have 20 columns or 4 columns). Problem Say I have 8 data points (and thus 8 columns) in my original dataset. When I update the chart with random data, the columns appropriately adjust their height to the new values - but new bars aren't added. Additionally, while the width of the columns appropriately adjust to accommodate the width of the container and the new number of data points, if that number of data points is less than the original set, then some of those columns from the original dataset will linger until the number of data points is greater than or equal than the original. My end goal is to have new data dynamically added or old data outside of the range of the new data count dynamically removed. I've created a jsfiddle of the behavior. You may have to click the columns a couple of times to see the behavior I'm describing. Additionally, I've pasted my code below. Thanks in advance! function chart(config) { // set default options var defaultOptions = { selector: '#chartZone', class: 'chart', id: null, data: [1,2,6,4, 2, 6, 7, 2], type: 'column', width: 200, height: 200, callback: null, interpolate: 'monotone' }; // fill in unspecified settings in the config with the defaults var settings = $.extend(defaultOptions, config); function my() { // generate chart with this function var w = settings.width, h = settings.height, barPadding = 3, scale = 10, max = d3.max(settings.data); var svg = d3.select(settings.selector) // create the main svg container .append("svg") .attr("width",w) .attr("height",h); var y = d3.scale.linear().range([h, 0]), yAxis = d3.svg.axis().scale(y).ticks(5).orient("left"), x = d3.scale.linear().range([w, 0]); y.domain([0, max]).nice(); x.domain([0, settings.data.length - 1]).nice(); var rect = svg.selectAll("rect") .data(settings.data) .enter() .append("rect") .attr("x", function(d,i) { return i * (w / settings.data.length); }) .attr("y", function(d) { return h - h * (d / max); }) .attr("width", w / settings.data.length - barPadding) .attr("height", function(d) { return h * (d / max); }) .attr("fill", "rgb(90,90,90)"); svg.append("svg:g") .attr("class", "y axis") .attr("transform", "translate(-4,0)") .call(yAxis); svg.on("click", function() { var newData = [], maxCap = Math.round(Math.random() * 100); for (var i = 0; i < Math.round(Math.random()*100); i++) { var newNumber = Math.random() * maxCap; newData.push(Math.round(newNumber)); } newMax = d3.max(newData); y.domain([0, newMax]).nice(); var t = svg.transition().duration(750); t.select(".y.axis").call(yAxis); rect.data(newData) .transition().duration(750) .attr("height", function(d) { return h * (d / newMax); }) .attr("x", function(d,i) { return i * (w / newData.length); }) .attr("width", w / newData.length - barPadding) .attr("y", function(d) { return h - h * (d / newMax); }); }); } my(); return my; } var myChart = chart();

  • How to isolate data per customer, Django powered website

    - by Sawwy
    I have recently started learning python and django and working on a project that includes building a website for collecting information from customers. I am currently trying to figure out best way to isolate the customer data (collected information is sensitive and should only be accessible by customer and the service provider). I found this post Postgresql - one database for everyone, or one-database per customer and my question is that can I automate the model inheritance with customer creation via admin? To be specific, when save() is called for adding customer via django admin, this should create the customer specific tables (create a new set of tables with 'company_name' -prefix). For more information of the environment, I have extended the basic user registration with custom UserProfile adding 'company' and 'role' fields for each user. Upon login, the 'company' of the user will be checked to filter out tables without the 'company_name' prefix. 'Role' will further filter the which company-specific tables and set rights (view, edit). will appreciate any suggestions if more elegant methods could be used to solve the data isolation problem than model inheritance.

  • Solution Items in Visual Studio 2005/2008

    - by Muneeb
    Is it possible to add a class as a solution item and use it as a linked item in all the projects in the solution? Basically I was thinking of creating a class (which will inherit ConfigurationSection) and keeping it as the Solution Item. I wanted to add it as a linked item in all the projects in the solution, so that everyone can use it to access the configuration properties. (Refer to this tutorial for more details) Now the issue I am facing is that when I create a class in the solution item, it doesn't have any namespace. And it shows up in intellisense, inside the projects but once I create an object of the solution item class, the object doesn't show up in intellisense. Any ideas why?

  • Script SQL Server login with Windows authentication without machine name

    - by Evgeny
    I want to write a SQL 2005 script to create a new login that uses Windows authentication. The Windows user is a local account (not a domain one). A local account with the same name exists on many SQL Server machines and I want to run the same script on all of them. It seemed simple enough: CREATE LOGIN [MyUser] FROM WINDOWS However, that doesn't work! SQL returns an error, saying Give the complete name: <domain\username>. Of course, I can do that for one machine and it works, but the same script will not work on other machines.

  • Extending both T and SomeInterface<T> in Java

    - by Graeme Moss
    I want to create a class that takes two parameters. One should be typed simply as T. The other should be typed as something that extends both T and SomeInterface. When I attempt this with public class SomeClass<T, S extends SomeInterface<T> & T> then Java complains with "The type T is not an interface; it cannot be specified as a bounded parameter" and if instead I attempt to create an interface for S with public interface TandSomeInterface<T> extends SomeInterface<T>, T then Java complains with "Cannot refer to the type parameter T as a supertype" Is there any way to do this in Java? I think you can do it in C++...?

  • Migrate a Django project from MySQL to Oracle

    - by pablo
    Hi, I have a Django1.1 project that works with a legacy MySQL db. I'm trying to migrate this project to Oracle (xe and 11g). We have two options for the migration: - Use SQL developer to create a migration sql script. - Use Django fixtures. The schema created with the sql script from sql developer doesn't match the schema created from syncdb. For example, Django expects TIMESTAMP columns while sql developer creates DATE columns. Using syncdb with Django fixtures could be great but when trying to load the MySQL fixtures into Oracle, after using syncdb, I'm getting: IntegrityError: ORA-00001: unique constraint (USER.SYS_C004253) violated How can I find what part create the integrity error?

  • logging in scala

    - by IttayD
    In Java, the standard idiom for logging is to create a static variable for a logger object and use that in the various methods. In Scala, it looks like the idiom is to create a Logging trait with a logger member and mixin the trait in concrete classes. This means that each time an object is created it calls the logging framework to get a logger and also the object is bigger due to the additional reference. Is there an alternative that allows the ease of use of "with Logging" while still using a per-class logger instance? EDIT: My question is not about how one can write a logging framework in Scala, but rather how to use an existing one (log4j) without incurring an overhead of performance (getting a reference for each instance) or code complexity. Also, yes, I want to use log4j, simply because I'll use 3rd party libraries written in Java that are likely to use log4j.

  • NerdDinner difficulties

    - by George
    Hello guys, I'm having a problem with the Create method of the NerdDinner tutorial, which is very good BTW. As you can see here http://nerddinnerbook.s3.amazonaws.com/Part5.htm in the Create method, he removed the ID field of the aspx page. I did that too, but I cannot add any dinners because I get a primary key violation. How is NerdDinner controlling the ids of each dinner? I revised the tutorial and could not see any references to identity fields on SQL database. I even created a method to get me the highest id in the table: public int GetHighestDinnerId() { int resultado = (from dinner in dataContext.Dinners select dinner.DinnerId).Max(); return resultado; } which does not work either. Any thoughts? Thank you

  • Images to video - converting to IplImage makes video blue
