• profiling WCF services with visual studio profiler

  - by ashish.s

  I am trying to profile a WCF service using visual studio profiler. So i created a profile by choosing asp.net application, and gave it the url of the web service. When i launch the session, it launches a web page to the site. I then run my unit test using another visual studio client, but the test always fails with with communication exception, and the process that performance analyze is attached to exits out. if i run the test again, it attached the process again, but the tests still fails with communication exception. This is throwing my report off since its only accounting for the startup work that the application is supposed to do. can someone point out what i am doing wrong ?

• Selenium and Headless Environment

  - by sdmythos_gr

  I recently installed Python 2.7, Robot Framework and the Selenium Library (I still don't know if I succeded though...) on a Red Hat Server to run some test on a web application. So I tried a simple test case using the robot framework to see if Selenium Library is functional, just to Open a web page, nothing more... Selenium Server is up and running according to the result of ps, and firefox binaries are in the PATH... Running the test case from the Robot Framework (with the pybot testcasename.tsv) I get an exception: ERROR: Problem capturing a screenshot to string: java.awt.AWTException: headless environment So, what is the Headless Environment? Does anyone have an idea if there is something else that needs to be istalled or to be configured as well?

• TFS Load Testing Web Tests

  - by durilai

  I am configuring a load test and am curious/confused on settings. I am testing an intranet website, that is expected to have 6000 concurrent users. My employer had some previous consultant tell them that the load test users does not matter and that we need to worry about requests/second. They have previously determined that those 6000 users would generate 30 rps, while I feel that is not correct we need to show that we can exceed that number. The previous load test was set for only 200 users and the results showed that it did exceed the 200 rps. They were happy with the results, but that is not how I understand this. My question is, if we need to support 6000 concurrent users should I just set my users to 6000 and run, or is the rps an adequate piece of data to rely on? Any help is appreciated. Thanks

• Is TDD broken in Python?

  - by Konstantin

  Hi! Assume we have a class UserService with attribute current_user. Suppose it is used in AppService class. We have AppService covered with tests. In test setup we stub out current_user with some mock value: UserService.current_user = 'TestUser' Assume we decide to rename current_user to active_user. We rename it in UserService but forget to make change to its usage in AppService. We run tests and they pass! Test setup adds attribute current_user which is still (wrongly but successfully) used in AppService. Now our tests are useless. They pass but application will fail in production. We can't rely on our test suite == TDD is not possible. Is TDD broken in Python?

• WCF binding programatically and adding metadata excange

  - by totem

  Hi, My problem is im trying to enable mex on a service that uses net.tcp binding. that binding is for localhost port 5000, when i want to enable mex on the same port, and have it avilable for http i have to enable the HttpGetEnabled on the Service host. All this works well but when i try to add the binding it fails becuase the binding is "net.tcp://localhost:5000/test". is there a way to enable mex on the same port but with a diffrent uri? Without enableing NetTcpPortSharing. I dont think the code is the issue since i can add the MEX on a diffrent port through the code an it works fine, the question is how to have net.tcp://localhost:5000/test as the WCF tcp based enpoint and net.tcp://localhost:5000/test/mex as the http mex endpoint that gives the WSDL for the TCP endpoint. thanks, Totem

• Response.Redirect with a fragment identifier causes unexpected refresh when later using location.has

  - by Matt

  Hi All, I was hoping someone can assist in describing a workaround solution to the following issue I am running into on my ASP.NET website on IE. In the following I will describe the bug and clarify the requirements of the needed solution. Repro Steps: User visits A.aspx A.aspx uses Response.Redirect to bring the user to B.aspx#house On B.aspx#house, the user clicks a button that sets window.location.hash='test' Actual Results: B.aspx is loaded again. The URL now shows B.aspx#test Expected Results: No reload. The URL will just change to B.aspx#test Requirements: Page A must redirect to page B with a fragment identifier in the url Any user action on page B will set the location.hash Setting location.hash must not make page B refresh This must work on IE Notes: Bug only repros on IE (tested on ie6|7|8). Opera, FF, Chrome, Safari all have the expected results of no reload. This error may have nothing to do with ASP.NET, and everything to do with IE For any kind soul willing to have a look at this, I have created a minimal ASP.NET web project to make it easy to repro here

• Android XMLRPC Fault Code

  - by sameersegal

  Hey, We have been using XMLRPC for android and it was working well until we got our hands dirty with Base64 encoding for byte[] (images) -- (we did base64_string.replace("/","$$") for transmission). We have tried undoing the changes and its looking an XMLRPC error. We are getting the following error in the DDMS: 06-10 23:27:02.970: DEBUG/Test(343): org.xmlrpc.android.XMLRPCFault: XMLRPC Fault: [code 0] 06-10 23:27:02.970: DEBUG/Test(343): at org.xmlrpc.android.XMLRPCClient.callEx(XMLRPCClient.java:308) 06-10 23:27:02.970: DEBUG/Test(343): at org.xmlrpc.android.XMLRPCMethod.run(XMLRPCMethod.java:33) Just before this I checked the body (xml message -- which is perfect) and the response received: 06-10 23:27:02.940: INFO/System.out(343): Response received: org.apache.http.message.BasicHttpResponse@437762f8 Since it the message is not even reaching our cloud, the issue is with XMLRPC for android. Any help will be most appreciated. Thanks Best Sameer

• Why is WPFToolkit DataGrid so slow when binding?

  - by Schneider

  I have a very simple test application where I have two objects, each with a small collection of items. when I select an object I display its collection in a WPFToolkit DataGrid. The problem is there is a noticeable delay, such that if you press up/down keys to toggle selection between objects you can see it can't keep up. Why is the performance so bad? <Window x:Class="SlowGridBinding.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" Title="MainWindow" Height="350" Width="525"> <StackPanel> <ListBox ItemsSource="{Binding Shops}" DisplayMemberPath="Name" IsSynchronizedWithCurrentItem="True"/> <Controls:DataGrid ItemsSource="{Binding Shops/Vegetables}" AutoGenerateColumns="True"/> </StackPanel> The DataContext is populated with some test classes filled with 50 items of random test data.

• Social Business Forum Milano: Day 2

  - by me

  @YourService. The business world has flipped and small business can capitalize  by Frank Eliason (twitter: @FrankEliason ) Technology and social media tools have made it easier than ever for companies to communicate with consumers. They can listen and join in on conversations, solve problems, get instant feedback about their products and services, and more. So why, then, are most companies not doing this? Instead, it seems as if customer service is at an all time low, and that the few companies who are choosing to focus on their customers are experiencing a great competitive advantage. At Your Service explains the importance of refocusing your business on your customers and your employees, and just how to do it. Explains how to create a culture of empowered employees who understand the value of a great customer experience Advises on the need to communicate that experience to their customers and potential customers Frank Eliason, recognized by BusinessWeek as the 'most famous customer service manager in the US, possibly in the world,' has built a reputation for helping large businesses improve the way they connect with customers and enhance their relationships Quotes from the Audience: Bertrand Duperrin ?@bduperrin social service is not about shutting up the loudest cutsomers ! #sbf12 @frankeliason Paolo Pelloni ?@paolopelloniGautam Ghosh ?@GautamGhosh RT @cecildijoux: #sbf12 @frankeliason you need to change things and fix the approach it's not about social media it's about driving change  Peter H.

• How to use WSDL2Java generated files?

  - by vikasde

  I generated the .java files using wsdl2java found in axis2-1.5. Now it generated the files in this folder structure: src/net/mycompany/www/services/ The files in the services folder are: SessionIntegrationStub and SessionIntegrationCallbackHandler. I would like to consume the webservice now. I added the net folder to the CLASSPATH environment variable. My java file now imports the webservice using: import net.mycompany.www.services; public class test { public static void main(String[] args) { SessionIntegrationStub stub = new SessionIntegrationStub(); System.out.println(stub.getSessionIntegration("test")); } } Now when I try to compile this using: javac test.java I get: package net.mycompany.www does not exist. Any idea?

• Programatically find TFS changes since last good build

  - by abigblackman

  I have several branches in TFS (dev, test, stage) and when I merge changes into the test branch I want the automated build and deploy script to find all the updated SQL files and deploy them to the test database. I thought I could do this by finding all the changesets associated with the build since the last good build, finding all the sql files in the changesets and deploying them. However I don't seem to be having the changeset associated with the build for some reason so my question is twofold: 1) How do I ensure that a changeset is associated with a particular build? 2) How can I get a list of files that have changed in the branch since the last good build? I have the last successfully built build but I'm unsure how to get the files without checking the changesets (which as mentioned above are not associated with the build!)

• Why doesn't Apache2::SubProcess spawn my subprocess?

  - by codeholic

  The following script works without errors, but /tmp/test.touch is not being created (even being checked later in the command line). It seems to me as if $r->spawn_proc_prog doesn't spawn a process. What may cause the problem? #!/usr/bin/perl use strict; use warnings; use Apache2::RequestUtil; use Apache2::SubProcess (); my $r = Apache2::RequestUtil->request; print "Content-Type: text/plain\n\n"; print eval { $r->spawn_proc_prog('/usr/bin/touch', ['/tmp/test.touch']) } ? `ls -l /tmp/test.touch` : $@;

• JSP Custom Taglib: Nested Evaluation

  - by Tiago Fernandez

  Say I have my custom taglib: <%@ taglib uri="http://foo.bar/mytaglib" prefix="mytaglib"%> <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%> <mytaglib:doSomething> Test </mytaglib:doSomething> Inside the taglib class I need to process a template and tell the JSP to re-evaluate its output, so for example if I have this: public class MyTaglib extends SimpleTagSupport { @Override public void doTag() throws JspException, IOException { getJspContext().getOut().println("<c:out value=\"My enclosed tag\"/>"); getJspBody().invoke(null); } } The output I have is: <c:out value="My enclosed tag"/> Test When I actually need to output this: My enclosed tag Test Is this feasible? How? Thanks.

• Remove characters after specific character in string, then remove substring?

  - by sah302

  I feel kind of dumb posting this when this seems kind of simple and there are tons of questions on strings/characters/regex, but I couldn't find quite what I needed (except in another language: http://stackoverflow.com/questions/2176544/remove-all-text-after-certain-point). I've got the following code: [Test] public void stringManipulation() { String filename = "testpage.aspx"; String currentFullUrl = "http://localhost:2000/somefolder/myrep/test.aspx?q=qvalue"; String fullUrlWithoutQueryString = currentFullUrl.Replace("?.*", ""); String urlWithoutPageName = fullUrlWithoutQueryString.Remove(fullUrlWithoutQueryString.Length - filename.Length); String expected = "http://localhost:2000/somefolder/myrep/"; String actual = urlWithoutPageName; Assert.AreEqual(expected, actual); } I tried the solution in the question above (hoping the syntax would be the same!) but nope. I want to first remove the queryString which could be any variable length, then remove the page name, which again could be any length. How can I get the remove the query string from the full URL such that this test passes?

• MVC2 Areas and unit testing for routes

• Objective-C (iPhone) Memory Management

  - by Steven

  I'm sorry to ask such a simple question, but it's a specific question I've not been able to find an answer for. I'm not a native objective-c programmer, so I apologise if I use any C# terms! If I define an object in test.h @interface test : something { NSString *_testString; } Then initialise it in test.m -(id)init { _testString = [[NSString alloc] initWithString:@"hello"]; } Then I understand that I would release it in dealloc, as every init should have a release -(void)dealloc { [_testString release]; } However, what I need clarification on is what happens if in init, I use one of the shortcut methods for object creation, do I still release it in dealloc? Doesn't this break the "one release for one init" rule? e.g. -(id)init { _testString = [NSString stringWithString:@"hello"]; } Thanks for your helps, and if this has been answered somewhere else, I apologise!!

• Java Classpath Problems in Ubuntu

  - by Travis

  First off I'm running Ubuntu 9.10 I've edited the /etc/environment file to look like this: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.20" CLASSPATH="/home/travis/freetts/lib/freetts.jar:/home/travis/freetts/lib/jsapi.jar:." I then run "source /etc/environment" to make sure the changes are included. Then I try compiling my simple test program using this: javac Test.java It throws out a few errors, but when I compile like this: javac -cp /home/travis/freetts/lib/freetts.jar:/home/travis/freetts/lib/jsapi.jar:. Test.java It works just fine, this leads me to believe that for some reason javac isn't seeing the CLASSPATH environment variable? I can echo it and everything in the terminal: echo $CLASSPATH gives me what I put in. Any help on this would be greatly appreciated.

• Apache/passenger/ree doesn't interpret .rb files

  - by Sergey

  I'm trying to get apache + passenger + ree to work. I think I did everything (except for setting up rails env - for now I wanna run just pure ruby) described here: http://rvm.beginrescueend.com/integration/passenger/ But when I try to go to localhost/test.rb it doesn't interpret that file and just download it. I don't know where should I look for mistakes, so here are a few files I think could be relevant: /var/log/apache2/error.log (these 2 lines are repeating) [Mon May 31 23:12:47 2010] [notice] Graceful restart requested, doing restart [Mon May 31 23:12:48 2010] [notice] Apache/2.2.14 (Ubuntu) PHP/5.3.2-1ubuntu4.2 with Suhosin-Patch Phusion_Passenger/2.2.11 configured -- resuming normal operations /etc/apache2/httpd.conf LoadModule passenger_module /home/sergey/.rvm/gems/ree-1.8.7-2010.01/gems/passenger-2.2.11/ext/apache2/mod_passenger.so PassengerRoot /home/sergey/.rvm/gems/ree-1.8.7-2010.01/gems/passenger-2.2.11 PassengerRuby /home/sergey/.rvm/bin/passenger_ruby /var/www/test.rb puts "test"

• ASP.Net UpdatePanel, want to have html-tag as a parameter

  - by Nordis

  This is my problem, I have one textbox, one button and one label. Everything is inside an updatepanel. Let's say I want to test if a valid html-tag is entered in the textbox when I press the button. In the code-behind I have a method for that. Everythings works just fine, except when I actually enter a html-tag in my textbox. If I test < html, it works. But not if I test . So my question is, doesn't the updatepanel accept html-tags as parameters? Because my breakpoint for the button_click doesn't triggers. Sorry for my bad english.. :)

• TFSBuild.Proj and Manual SQL Server Work Help?

  - by ScSub

  Using the VS 2008 GDR update, I have created a database project. I have created a SQL Server deployment package. I have created a database unit test. Using some wizards, the stuff got into my tfsbuild.proj file so near the end of the automated build process a database is created. I lack a little control of the whole process, I now see. What I would like to do is manually deploy the DB, run 3 custom scripts against the DB, and then manually start the DB unit test. I have other non-DB unit tests that already run. I do not want to use VSMDI or ordered unit test stuff because in out multi-developer environment it gets messy. Help!

• MSBuild Include Remote File 2008?

  - by ScSub

  TFS 2008, VS 2008. I have a tfsbuild.proj and tfsbuild.msp file in $/MyStuff/TeamBuildTypes/Dev folder. I have a targets file at $/MyStuff/TeamBuildTypes/IncludeFiles/Common/test.xml. test.xml contains an XML fragment that overrides the BeforeGet task. I tried to get the file into my tfsbuild.proj file like this: <Import Project="$/MyStuff/TeamBuildTypes/IncludeFiles/Common/test.xml" /> The build fails because it tries to get the file from a relative path that is way off. How can I specify external/include files from an explicit TFS "remote" path? Thanks.

• Java - short and casting

  - by chr1s

  Hi all, I have the following code snippet. public static void main(String[] args) { short a = 4; short b = 5; short c = 5 + 4; short d = a; short e = a + b; // does not compile (expression treated as int) short z = 32767; short z_ = 32768; // does not compile (out of range) test(a); test(7); // does not compile (not applicable for arg int) } public static void test(short x) { } Is the following summary correct (with regard to only the example above using short)? direct initializations without casting is only possible using literals or single variables (as long as the value is in the range of the declared type) if the rhs of an assignment deals with expressions using variables, casting is necessary But why exactly do I need to cast the argument of the second method call taking into account the previous summary?

• Optional query string parameters in URITemplate in WCF?

  - by Shafique

  I'm developing some RESTful services in WCF 4.0. I've got a method as below: [OperationContract] [WebGet(UriTemplate = "Test?format=XML&records={records}", ResponseFormat=WebMessageFormat.Xml)] public string TestXml(string records) { return "Hello XML"; } So if i navigate my browser to http://localhost:8000/Service/Test?format=XML&records=10, then everything works as exepcted. HOWEVER, i want to be able to navigate to http://localhost:8000/Service/Test?format=XML and leave off the "&records=10" portion of the URL. But now, I get a service error since the URI doesn't match the expected URI template. So how do I implement defaults for some of my query string parameters? I want to default the "records" to 10 for instance if that part is left off the query string.
