• .NET proxy detection

  - by Ziplin

  I am having an issue with .NET detecting the proxy settings configured through internet explorer. I'm writing a client application that supports proxies, and to test I set up an array of 9 squid servers to support various authentication methods for HTTP and HTTPs. I have a script that updates IE to whichever configuration I choose (which proxy, detection via "Auto", PAC, or hardcode). I have tried the 3 methods below to detect the IE configuration through .NET. On occassion I notice that .NET picks up the wrong set of proxy servers. IE has the correct settings, and if I browse the web with IE, I can see I am hitting the correct servers via wireshark. WebRequest.GetSystemWebProxy().GetProxy(destination); GlobalProxySelection.Select.GetProxy(destination); WebRequest.DefaultWebProxy Here are the following tips I have: My script sets a PAC file on a webserver, and updates the configuration in IE, then clears IE's cache .NET seems to get "stuck" on a certain proxy configuration, and I have to set another configuration for .NET to realize there was a change. Occasionally it seems to pick some random set of servers (I'm sure they're not random, just a set of servers I used once and are in some cached PAC file or something). As in, I will check the proxy for the destination "https://www.secure.com" and I may have IE configured for and thus expect to get "http://squidserver:18" and instead it will return "http://squidserver:28" (port 18 runs NTLM, 28 runs without authentication). All the squid servers work. This does not appear to be an issue on XP, only Vista, 2003, and windows 7. Hardcoding the proxy servers in IE ALWAYS works Time always solves the issue - if I leave the computer for about 20 or 30 minutes and come back, .NET picks up the correct proxy settings, as if a cached PAC script expired.

• How to Extract Properties for Refactoring

  - by Ngu Soon Hui

  I have this property public List<PointK> LineList {get;set;} Where PointK consists of the following structure: string Mark{get;set;} double X{get;set;} doible Y{get;set;} Now, I have the following code: private static Dictionary<string , double > GetY(List<PointK> points) { var invertedDictResult = new Dictionary<string, double>(); foreach (var point in points) { if (!invertedDictResult.ContainsKey(point.Mark)) { invertedDictResult.Add(point .Mark, Math.Round(point.Y, 4)); } } return invertedDictResult; } private static Dictionary<string , double > GetX(List<PointK> points) { var invertedDictResult = new Dictionary<string, double>(); foreach (var point in points) { if (!invertedDictResult.ContainsKey(point.Mark)) { invertedDictResult.Add(point .Mark, Math.Round(point.X, 4)); } } return invertedDictResult; } How to restructure the above code?

• How to control Time zone formatting in System.Xml.Serialization or during application execution?

  - by Beal

  I'm developing a C# .Net Application that is executing on a system located in the Central Time Zone. The application gets information from a third party using an API they provide. I have used the WSDL to produce the code that my application access the API with...their reporting API allows you to define a start date and end date for the report. These are C# DateTime fields and XSD:dateTime. Now when I set the start date and end dates and allow the API to create the SOAP messages the dates don't always include a Time Zone unless I set the date fields using the ToLocalTime method; however, the method will create the DateTime fields in the Central Time Zone (CST) but I need to have it create these fields in the Pacific Time Zone (PST). If I set my machine time to PST all is good...but of course that causes other time issues. What methods can I use to control the formatting of the DateTime? Alternatively, is there a application setting that can be set in C# that allows timezone control?

• DataGrid: dynamic DataTemplate for dynamic DataGridTemplateColumn

  - by Lukas Cenovsky

  I want to show data in a datagrid where the data is a collection of public class Thing { public string Foo { get; set; } public string Bar { get; set; } public List<Candidate> Candidates { get; set; } } public class Candidate { public string FirstName { get; set; } public string LastName { get; set; } ... } where the number of candidates in Candidates list varies at runtime. Desired grid layout looks like this Foo | Bar | Candidate 1 | Candidate 2 | ... | Candidate N I'd like to have a DataTemplate for each Candidate as I plan changing it during runtime - user can choose what info about candidate is displayed in different columns (candidate is just an example, I have different object). That means I also want to change the column templates in runtime although this can be achieved by one big template and collapsing its parts. I know about two ways how to achieve my goals (both quite similar): Use AutoGeneratingColumn event and create Candidates columns Add Columns manually In both cases I need to load the DataTemplate from string with XamlReader. Before that I have to edit the string to change the binding to wanted Candidate. Is there a better way how to create a DataGrid with unknown number of DataGridTemplateColumn? Note: This question is based on dynamic datatemplate with valueconverter

• Ant ignores attempt to override the LANG environment variable

  - by Steen

  We need to test a java build with the languages set to different values. I can manually (i.e. via export LANG=en_DK.UTF-8 and export LANG=en_DK) test that the unit tests run with the ant build script behaves differently, but I need to set the environment variable from ant. I have tried setting it using these methods (with the shell $LANG set to en_DK.UTF-8): using -D on the command line: ant -DLANG=en_DK using a build.properties file with the line LANG=en_DK in it using the following statements in the build.xml file (sorry for the formatting, I can't get SO to display it otherwise): : <property environment="ANTENV"/> <property name="ANTENV.LANG" value="en_DK"/> Using any of the three possibilities, and when run with -debug, ant reports that: Override ignored for property "LANG" What can I do to set the LANG environment variable from within ant?

• How to get `gcc` to generate `bts` instruction for x86-64 from standard C?

  - by Norman Ramsey

  Inspired by a recent question, I'd like to know if anyone knows how to get gcc to generate the x86-64 bts instruction (bit test and set) on the Linux x86-64 platforms, without resorting to inline assembly or to nonstandard compiler intrinsics. Related questions: Why doesn't gcc do this for a simple |= operation were the right-hand side has exactly 1 bit set? How to get bts using compiler intrinsics or the asm directive Portability is more important to me than bts, so I won't use and asm directive, and if there's another solution, I prefer not to use compiler instrinsics. EDIT: The C source language does not support atomic operations, so I'm not particularly interested in getting atomic test-and-set (even though that's the original reason for test-and-set to exist in the first place). If I want something atomic I know I have no chance of doing it with standard C source: it has to be an intrinsic, a library function, or inline assembly. (I have implemented atomic operations in compilers that support multiple threads.)

• Raphael.js: Adding a new custom element

  - by Claudia

  I would like to create a custom Raphael element, with custom properties and functions. This object must also contain predefined Raphael objects. For example, I would have a node class, that would contain a circle with text and some other elements inside it. The problem is to add this new object to a set. These demands are needed because non-Raphael objects cannot be added to sets. As a result, custom objects that can contain Raphael objects cannot be used. The code would look like this: var Node = function (paper) { // Coordinates & Dimensions this.x = 0, this.y = 0, this.radius = 0, this.draw = function () { this.entireSet = paper.set(); var circle = paper.circle(this.x, this.y, this.radius); this.circleObj = circle; this.entireSet.push(circle); var text = paper.text(this.x, this.y, this.text); this.entireSet.push(text); } // other functions } var NodeList = function(paper){ this.nodes = paper.set(), this.populateList = function(){ // in order to add a node to the set // the object must be of type Raphael object // otherwise the set will have no elements this.nodes.push(// new node) } this.nextNode = function(){ // ... } this.previousNode = function(){ // ... } }

• Daylight saving time of current tz

  - by spam2

  Hi, in my c++ software I've used Boost in some parts and also for the local time. OK, now my problem is to make a check if in my machine is active or not the DST. With the follow part of code I can know only the difference from the UTC time. In my case the difference is 2 hours because is active the DST ptime tLoc = second_clock::local_time(); ptime tUTC = second_clock::universal_time(); time_duration tDiff = tUTC - tLoc; local_time_zone = tDiff.hours(); I think that the boolean funcion has_dst() can help, right? My system is Debian GNU/Linux. Thanks

• Python sock.listen(...)

  - by Ian

  All the examples I've seen of sock.listen(5) in the python documentation suggest I should set the max backlog number to be 5. This is causing a problem for my app since I'm expecting some very high volume (many concurrent connections). I set it to 200 and haven't seen any problems on my system, but was wondering how high I can set it before it causes problems.. Anyone know?

• Is there a way to automaticly call all versions of an inherited method?

  - by Eric

  I'm writing a plug-in for a 3D modeling program. I have a custom class that wraps instances of elements in the 3D model, and in turn derives it's properties from the element it wraps. When the element in the model changes I want my class(es) to update their properties based on the new geometry. In the simplified example below. I have classes AbsCurveBasd, Extrusion, and Shell which are all derived from one another. Each of these classes implement a RefreshFromBaseShape() method which updates specific properties based on the current baseShape the class is wrapping. I can call base.RefreshFromBaseShape() in each implementation of RefreshFromBaseShape() to ensure that all the properties are updated. But I'm wondering if there is a better way where I don't have to remember to do this in every implementation of RefershFromBaseShape()? For example because AbsCurveBased does not have a parameterless constructor the code wont even compile unless the constructors call the base class constructors. public abstract class AbsCurveBased { internal Curve baseShape; double Area{get;set;} public AbsCurveBased(Curve baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public virtual void RefreshFromBaseShape() { //sets the Area property from the baseShape } } public class Extrusion : AbsCurveBased { double Volume{get;set;} double Height{get;set;} public Extrusion(Curve baseShape):base(baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public override void RefreshFromBaseShape() { base.RefreshFromBaseShape(); //sets the Volume property based on the area and the height } } public class Shell : Extrusion { double ShellVolume{get;set;} double ShellThickness{get;set;} public Shell(Curve baseShape): base(baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public void RefreshFromBaseShape() { base.RefreshFromBaseShape(); //sets this Shell Volume from the Extrusion properties and ShellThickness property } }

• Entity with Guid ID is not inserted by NHibernate

  - by DanK

  I am experimenting with NHibernate (version 2.1.0.4000) with Fluent NHibernate Automapping. My test set of entities persists fine with default integer IDs I am now trying to use Guid IDs with the entities. Unfortunately changing the Id property to a Guid seems to stop NHibernate inserting objects. Here is the entity class: public class User { public virtual int Id { get; private set; } public virtual string FirstName { get; set; } public virtual string LastName { get; set; } public virtual string Email { get; set; } public virtual string Password { get; set; } public virtual List<UserGroup> Groups { get; set; } } And here is the Fluent NHibernate configuration I am using: SessionFactory = Fluently.Configure() //.Database(SQLiteConfiguration.Standard.InMemory) .Database(MsSqlConfiguration.MsSql2008.ConnectionString(@"Data Source=.\SQLEXPRESS;Initial Catalog=NHibernateTest;Uid=NHibernateTest;Password=password").ShowSql()) .Mappings(m => m.AutoMappings.Add( AutoMap.AssemblyOf<TestEntities.User>() .UseOverridesFromAssemblyOf<UserGroupMappingOverride>())) .ExposeConfiguration(x => { x.SetProperty("current_session_context_class","web"); }) .ExposeConfiguration(Cfg => _configuration = Cfg) .BuildSessionFactory(); Here is the log output when using an integer ID: 16:23:14.287 [4] DEBUG NHibernate.Event.Default.DefaultSaveOrUpdateEventListener - saving transient instance 16:23:14.291 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - saving [TestEntities.User#<null>] 16:23:14.299 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - executing insertions 16:23:14.309 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - executing identity-insert immediately 16:23:14.313 [4] DEBUG NHibernate.Persister.Entity.AbstractEntityPersister - Inserting entity: TestEntities.User (native id) 16:23:14.321 [4] DEBUG NHibernate.AdoNet.AbstractBatcher - Opened new IDbCommand, open IDbCommands: 1 16:23:14.321 [4] DEBUG NHibernate.AdoNet.AbstractBatcher - Building an IDbCommand object for the SqlString: INSERT INTO [User] (FirstName, LastName, Email, Password) VALUES (?, ?, ?, ?); select SCOPE_IDENTITY() 16:23:14.322 [4] DEBUG NHibernate.Persister.Entity.AbstractEntityPersister - Dehydrating entity: [TestEntities.User#<null>] 16:23:14.323 [4] DEBUG NHibernate.Type.StringType - binding null to parameter: 0 16:23:14.323 [4] DEBUG NHibernate.Type.StringType - binding null to parameter: 1 16:23:14.323 [4] DEBUG NHibernate.Type.StringType - binding 'ertr' to parameter: 2 16:23:14.324 [4] DEBUG NHibernate.Type.StringType - binding 'tretret' to parameter: 3 16:23:14.329 [4] DEBUG NHibernate.SQL - INSERT INTO [User] (FirstName, LastName, Email, Password) VALUES (@p0, @p1, @p2, @p3); select SCOPE_IDENTITY();@p0 = NULL, @p1 = NULL, @p2 = 'ertr', @p3 = 'tretret' and here is the output when using a Guid: 16:50:14.008 [4] DEBUG NHibernate.Event.Default.DefaultSaveOrUpdateEventListener - saving transient instance 16:50:14.012 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - generated identifier: d74e1bd3-1c01-46c8-996c-9d370115780d, using strategy: NHibernate.Id.GuidCombGenerator 16:50:14.013 [4] DEBUG NHibernate.Event.Default.AbstractSaveEventListener - saving [TestEntities.User#d74e1bd3-1c01-46c8-996c-9d370115780d] This is where it silently fails, with no exception thrown or further log entries. It looks like it is generating the Guid ID correctly for the new object, but is just not getting any further than that. Is there something I need to do differently in order to use Guid IDs? Thanks, Dan.

• jquery $(window).width() and $(window).height() return different values when viewport has not been r

  - by Manca Weeks

  I am writing a site using jquery that repeatedly repeatedly calls $(window).width() and $(window).height() to position and size elements based on the viewport size... In troubleshooting I discovered that I am getting slightly different viewport size reports in repeated calls to the above jquery functions when the viewport is not resized... Wondering if there is any special case anyone knows of when this happens, or if this is just the way it is. The difference in sizes reported are 20px or less, it appears. It happens in Safari 4.0.4, Firefox 3.6.2 and Chrome 5.0.342.7 beta on Mac OS X 10.6.2... I didn't test other browsers yet because it doesn't appear to be specific to the browser. I was also unable to figure out what the difference depends upon - if it isn't the viewport size, could there be another factor that makes the results differ? Any insight would be appreciated... Thanks MAnca

• Is there any way to delete an HttpOnly cookie from C# Selenium tests?

  - by BenA

  I have a set of C# Selenium tests that need to delete a cookie that has the HttpOnly flag set. Unfortunately the DefaultSelenium.GetCookie() and DefaultSelenium.DeleteCookie() commands aren't able to access the cookie, because it has that HttpOnly flag set. I've confirmed this by removing the flag by hand, and checking that subsequent calls to either of those methods are then happily able to manipulate the cookie in question. Is there any other way to do this via the Selenium .NET client driver? All ideas welcome!

• How can I instantiate a base class and then convert it to a derived class?

  - by Eric

  I was wondering how to do this, consider the following classes public class Fruit { public string Name { get; set; } public Color Color { get; set; } } public class Apple : Fruit { public Apple() { } } How can I instantiate a new fruit but upcast to Apple, is there a way to instantiate a bunch of Fruit and make them apples with the name & color set. Do I need to manually deep copy? Of course this fails Fruit a = new Fruit(); a.Name = "FirstApple"; a.Color = Color.Red; Apple wa = a as Apple; System.Diagnostics.Debug.Print("Apple name: " + wa.Name); Do I need to pass in a Fruit to the AppleCTor and manually set the name and color( or 1-n properties) Is there an better design to do this?

• How to increase Java heap space for a tomcat app

  - by Ankur

  There are lots of questions that ask this or a similar question. They all give the command that has to be executed, what I don't understand is where do I write this command. I want to permanently increase the heap space for my tomcat apps. I read this page http://javahowto.blogspot.com/2006/06/6-common-errors-in-setting-java-heap.html and it says under the Tomcat section Stop Tomcat server, set environment variable CATALINA_OPTS, and then restart Tomcat. Look at the file tomcat-install/bin/catalina.sh or catalina.bat for how this variable is used. For example, set CATALINA_OPTS=-Xms512m -Xmx512m (Windows, no "" around the value) export CATALINA_OPTS="-Xms512m -Xmx512m" (ksh/bash, "" around the value) setenv CATALINA_OPTS "-Xms512m -Xmx512m" (tcsh/csh, "" around the value) So I replaced the line set CATALINA_OPTS= with set CATALINA_OPTS=-Xms512m -Xmx512m But I still get the error.

• Reset element to "default" event

  In Javascript, how can you set the event handler of a DOM element to default behavior? For example, suppose I set the onkeypress event of an input element: elem.onkeypress = function() { alert("Key pressed!"); } Later, how can I remove this event? Is it okay to simply set the onkeypress property to null? I tried that and it works, but I don't know if it is the proper way to do this.

• .NET chart Datamanipulator

  - by peter

  In .NET C#4.0 with the .NET Chart control I have this code to generate a pie chart: chart.Series[0].ChartType = SeriesChartType.Pie; foreach (Order order in orderCollection) { // If I set point.LegendText = order.UserName, .Group will erase it chart.Series[0].Points.AddXY(order.UserName, order.Total); } chart.DataManipulator.Sort(PointSortOrder.Ascending, "X", "Series1"); chart.DataManipulator.Group("SUM", 1, IntervalType.Months, "Series1"); This works well, it generates a pie chart with the top 10 users showing their total order sum. I would like to set the DataPoints' legendtext to the order.UserName property. The problem is, DataManipulator.Group overwrites the series DataPoints. So if I set the legendtext in the foreach loop, they will be erased after the Group call. And after the Group call, I don't see a way to retrieve the correct UserName for a DataPoint to set the legendtext. What is the best approach for this situation?
