• Concurrency Violation in NHibernate( c#) example

  - by vijaysylvester

  For quite some time , I was reading about the optimistic concurrency in NHibernate. If what i understood was correct then the below sample should hold good. Consider two transactions T1 and T2. When T1 and T2 are done simultaneously , the state(DB entries) gets updated with the values of the most latest update.(T1 or T2). Though it seems to be conceptually sound , how do i simulate this for the purpose of understanding and integration testing.? Can someone help me with a sample c# code.? Thanks , vijay

• uppercase to lowercase in bash on a mac

  - by Mala

  Hi I'm writing a bash script which needs to convert a string to lowercase. The problem is I'm doing it on a mac so 'tr' is not available. How can I go about doing this on a mac? The problem I'm trying to tackle is that my script needs to recognize an if an extension is a .gif or a .jpg - and I don't want to have to check for .jpeg, .jPeg, .JPEG, .JPeg, etc etc etc... if there's a smarter way of doing this than just converting to lowercase and testing for gif, jpg and jpeg, i'm all ears :)

• Any serious problems when making an old java web app run on new IE 8 browser?

  - by pinichi

  I need make an quick estimation on project (not sure we got): It's an old banking CMS java web app: Server: jdk5, weblogic 9. Client: winXP, Ie6. It was design only for use with ie6 but now we need make it also run well on new client: ie8,ie7 on win7. I understand the most difference is the client: DOM and CSS. But my problem is we hasn't been worked with ie8, and I have not enough time to build an testing environment because our developing environment is not ready to make test (its remoting completely, and managed by another partner) Any experience or suggestion to help me weighing this task need will be welcomed.

• ASP.NET MVC - creating and handling with URLs with Greater Than and Less Than characters

  - by pcampbell

  Consider a link to a page for a user's profile. A page is creating that URL like this: //Model.Name has value "<bad guy>" Html.ActionLink("foo, "ViewUser", new { id=5, title=Url.Encode(Model.Name) }) The actual outcome was http://mysite/Users/5/%253cbad%2guy%253e When navigating to that URL, the server generates a HTTP Error 400 - Bad Request. Question: Given that the Model.Name may contain Unicode characters, or characters otherwise illegal in URLs, what's the best way to strip out illegal characters, or otherwise encode them? The problem surfaces when testing out 'interesting' user inputs with < and >, but anything could come from the user, and therefore be put in a URL by way of Model.Name.

  Testing of Network Connection can be done by following method: public boolean isNetworkAvailable() { ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = cm.getActiveNetworkInfo(); if (networkInfo != null && networkInfo.isConnected()) { return true; } return false; } But i don't know how to check the server connection.I had followed this method public boolean isConnectedToServer(String url, long timeout) { try{ URL myUrl = new URL(url); URLConnection connection = myUrl.openConnection(); connection.setConnectTimetout(timeout); connection.connect(); return true; } catch (Exception e) { // Handle your exceptions return false; } } it doesn't works....Any Ideas Guys!!

• How to use Watin 64-bit with MSIE 32-bit

  - by dontomaso

  Hi, I have a C#-application running on Windows 7. I am using Watin to test some flash and quicktime movies in Internet Explorer. I am running in x64 mode due to some memory limitations I encountered in x86-mode. So I run my application which uses Watin, which starts MSIE. Watin starts the 64-bit version of MSIE. So far so good. The problem is, flash and quicktime do not seem to work in MSIE 64-bit, so testing playing of movies will not work. What must be done to run my C# application in 64-bit mode but to get Watin to run MSIE in 32-bit mode?

• 640 enterprise library caching threads - how?

  - by JohnW

  We have an application that is undergoing performance testing. Today, I decided to take a dump of w3wp & load it in windbg to see what is going on underneath the covers. Imagine my surprise when I ran !threads and saw that there are 640 background threads, almost all of which seem to say the following: OS Thread Id: 0x1c38 (651) Child-SP RetAddr Call Site 0000000023a9d290 000007ff002320e2 Microsoft.Practices.EnterpriseLibrary.Caching.ProducerConsumerQueue.WaitUntilInterrupted() 0000000023a9d2d0 000007ff00231f7e Microsoft.Practices.EnterpriseLibrary.Caching.ProducerConsumerQueue.Dequeue() 0000000023a9d330 000007fef727c978 Microsoft.Practices.EnterpriseLibrary.Caching.BackgroundScheduler.QueueReader() 0000000023a9d380 000007fef9001552 System.Threading.ExecutionContext.runTryCode(System.Object) 0000000023a9dc30 000007fef72f95fd System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object) 0000000023a9dc80 000007fef9001552 System.Threading.ThreadHelper.ThreadStart() If i had to give a guess, I'm thinkign that one of these threads are getting spawned for each run of our app - we have 2 app servers, 20 concurrent users, and ran the test approximately 30 times...it's in the neighborhood. Is this 'expected behavior', or perhaps have we implemented something improperly? The test ran hours ago, so i would have expected any timeouts to have occurred already.

• SqlDateTime overflow thrown by Typed DataSet Insert

  - by end-user

  I'm using a Typed DataSet with an Insert statement; I have a table that has a smalldatetime field defined to accept null values. When I insert from a .NET 2.0 FormView, I get a "SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM." Now, I've read this post, and the parameter as sent to the class constructor is defined as global::System.Nullable<global::System.DateTime> DoB So, it looks like it should accept a Nullable obj. Additionally, the generated code is testing the value sent. if ((DoB.HasValue == true)) { command.Parameters[6].Value = ((System.DateTime)(DoB.Value)); } else { command.Parameters[6].Value = global::System.DBNull.Value; } Specifically, the error is occurring when generated SqlClient.SqlCommand.ExecuteScalar() runs: try { returnValue = command.ExecuteScalar(); } So, I guess my question is: how do I use a Typed DataSet to set a blank value (passed from a FormView on CommandName=Insert) to a null in a database?

• ASP.NET MVC TDD with LINQ and SQL database

  - by dean nolan

  I am trying to start a new MVC project with tests and I thought the best way to go would have 2 databases. 1 for testing against and 1 for when I run the app and use it (also test really as it's not production yet). For the test database I was thinking of putting create table scripts and fill data scripts within the test setup method and then deleting all this in the tear down method. I am going to be using Linq to SQL though and I don't think that will allow me to do this? Will I have to just go the ADO route if I want to do it this way? Or should I just use a mock object and store data as an array or something?. Any tips on best practices? How did Jeff go about doing this for StackOveflow?

• is_tarfile() returns True for a blank file

  - by Zachary Young

  Hello all, I am testing some logic to handle a user uploading a TAR file. When I feed a blank file to tarfile.is_tarfile() it returns True, which is not what I am expecting: $ touch tartest $ cat tartest $ python -c "import tarfile; print tarfile.is_tarfile('tartest')" True If I add some text to the file, it returns False, which I am expecting: $ echo "not a tar" > tartest $ python -c "import tarfile; print tarfile.is_tarfile('tartest')" False I could add a check at the beginning to check for a zero-length file, but based on the documentation for tarfile.is_tarfile(name) I think this is unecessary: Return True if name is a tar archive file, that the tarfile module can read. I went so far as to check the source, tarfile.py, and I can see that it is checking header blocks but I do not fully understand how it is evaluating those blocks. Am I misreading the documentation and therefore setting unfair expectations? Thank you, Zachary

• Vertex Buffer Object not drawing in SDL window

  - by intregus

  I'm just using the opengl SDL template with Xcode, and everything runs fine. I removed the Atlantis code, and changed the main extension to .mm, then added some testing code to drawGL. Drawing a simple triangle (using immediate mode) at this point inside drawGL gives me a white triangle, but when I add the code to draw using a vertex buffer object, i just get a black window. Here is my VBO drawing code: glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // Clear The Screen And The Depth Buffer glLoadIdentity(); GLuint buffer; float vertices[] = { 0.0f, 1.0f, 0.0f, -1.0f,-1.0f, 0.0f, 1.0f,-1.0f, 0.0f }; // VBO doesn't work :( glGenBuffers(1, &buffer); glBindBuffer(GL_ARRAY_BUFFER, buffer); glBufferData(GL_ARRAY_BUFFER, sizeof(float) * 9, vertices, GL_STATIC_DRAW); glEnableClientState(GL_VERTEX_ARRAY); glVertexPointer(3, GL_FLOAT, 0, vertices); glDrawArrays(GL_TRIANGLES, 0, 3); glDisableClientState(GL_VERTEX_ARRAY);

• How does Windows decide which icon format to display when showing an exe's icon in Windows Explorer?

  - by Malcolm

  How does Windows decide which icon format to display when showing an exe's icon in Windows Explorer? Problem: When we look at our icon file and exe with embedded icon file in various Windows Explorer file views, the icon file is displayed in a higher quality mode than the icon displayed for our executable even though the icon in our executable contains the exact same icon. Our exe's icon has jaggier edges which leads me to believe that Windows Explorer may be trying to upsize a lower resolution icon rather than picking an icon appropriate for the actual display size. In a multi-format icon file, is there a specific order we should use for positioning each icon format? For example, we have an icon file with icons in the following formats: - 16x16 - 32x32 - 48x48 - 64x64 - 128x128 - 256x256 We are testing the appearance of our exe's icon using Windows Explorer under Windows XP, Vista and Windows 7. Any suggestions appreciated.

• Deploying WPF application: .NET 3.5 issues

  - by Robbert Dam

  Hi all, Users around my country are currently beta-testing our application. My app uses WPF & Linq, so I need .NET 3.5 installation. On most system, everything works find, including automatic installation on .NET 3.5 on machines that do not have that installed yet. However, on one machine (XP SP2) my application does not run. The user reported no issues during .NET 3.5 installation (except for a process that need to close before the installer could continue - he closed the process and continued). The application crashes on startup. To debug this issue, I did the following: Have him reboot his machine Let him manually re-install the .NET 3.5 framework (no errors reported) Have him run a test WPF app that only displays a button - also crashes Let him send the .NET 3.5 installation logs - these are huge, don't now where to look Does anyone have strategy on how to debug such issues? I expect that this will occur more when the application is released..

• Why is my ServiceOperation method missing from my WCF Data Services client proxy code?

  - by Kev

  I have a simple WCF Data Services service and I want to expose a Service Operation as follows: [System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults = true)] public class ConfigurationData : DataService<ProductRepository> { // This method is called only once to initialize service-wide policies. public static void InitializeService(IDataServiceConfiguration config) { config.SetEntitySetAccessRule("*", EntitySetRights.ReadMultiple | EntitySetRights.ReadSingle); config.SetServiceOperationAccessRule("*", ServiceOperationRights.All); config.UseVerboseErrors = true; } // This operation isn't getting generated client side [WebGet] public IQueryable<Product> GetProducts() { // Simple example for testing return (new ProductRepository()).Product; } Why isn't the GetProducts method visible when I add the service reference on the client?

• missing event when using modules with requirejs

  - by ali haider

  I had javascript code in a single JS file that was working fine (using XHR/AJAX). When I split it up into separate modules in a requirejs application, I do not seem to get a handle on the event object & it shows up as undefined (testing in firefox 29.0.1). Calling module: ajax.onreadystatechange = new ajaxResponse().handleAjaxResponse(e); ajaxResponse define(["require", './url/urlCommon'], function(require, urlCommon) { 'use strict'; var ajaxResponse = function() { var ajax = null; // e = event || window.event; this.handleAjaxResponse = function() { if (typeof event === 'undefined') { var event = event || window.event; } console.log('e is now:' + typeof e); I also do not have a handle on the event in the handleAjaxResponse method (error: undefined). Any thoughts on what I need to do to troubleshoot/fix this will be greatly appreciated.

• Problem with DWR and Android-Browser

  - by moxn

  Hello everyone, I am experiencing a problem with accessing an application from the Android-browser. The application uses DWR to persist connections to the clients that are connected with it. Everything works fine for me, except that if the application does not send any data to the client on the Android-phone for 2 minutes, the connection seems to be lost and no data arrive at the client. The same scenario works just fine on Firefox, Opera and Chrome. If the pause between two data transfers is less than 2 minutes, it works just fine. So, now my question: Is there some timeout setting for the android browser that I am missing? Or is this some built-in bug/feature/whatever that I cannot circumvent? I know that I could prevent this from happening with some sort of heartbeat, I would just like to why this is happening. Thanks in advance, Max btw: Everything (server, clients) runs on my machine and I am testing this on the android emulator with Windows XP Android emulator version 1.10 (build_id CUPCAKE-150240)

• Syncing google calendar with custom calendar

  - by yogsma

  I am using google calendar API to sync google calendar with our custom calendar. Right now I am trying it with a crude way by asking user if he/she wants to sync their calendar with google or not. If they say "yes" , I show them login screen where they have to enter their google user id and password and the calendar will be synced. But now when I change the month , the screen gets refreshed and all login information is lost and that changed month doesn't show up the events from google calendar. What is a best way for authentication AuthSub, OAuth or the crude way I mentioned for testing locally? I really don't know if I can use OAuth locally.

• Ruby on Rails protect_from_forgery best practice

  - by randombits

  I'm currently working on building a RESTful web api with ruby on rails. I haven't bothered putting a proper authentication scheme into the API yet as I'm ensuring that tests and the basic behavior of the API is working all locally first. Upon testing non-HTTP GET type requests such as HTTP POST/DELETE/PUT, stuff chokes because protect_from_forgery is on by default. How does this work when I'm working in practice since essentially the idea is in a RESTful API that there is no state. The client does not have a session or a cookie associated with the server. Each request is an atomic, self-executed request. The user will supply some credentials to ensure they are who they say they are, but other than that, does protect_from_forgery make sense at this point? Should it remain enabled?

• Project roles discovery

  - by Lirik

  I have a school project in which we're going to write a financial engine prototype by a group of 4 people. Most of us have never met each other before, so I'm trying to create a questionnaire to help us find the appropriate roles for each team-member. We have the following responsibilities: Database design Programming User interface design Training Documentation / technical writing Network design Project management Business analysis Testing And we have the following roles: Project Manager Developer Tester Business Analyst Our group has people with various experience: a full-time graduate student, an associate director at the CME (Chicago Mercantile Exchange), full-time professionals, etc. Do any of you know of any tools that would help build a questionnaire or do you have a reference to an online questionnaire that can help us identify the most suitable role(s) for each team member?

• How do I set the color for the editButtonItem in the navigation bar of a UITableViewController ?

  - by eemceebee

  Hi I have a UITableViewController where I added a "editButtonItem" in the navigation bar : self.navigationItem.leftBarButtonItem = self.editButtonItem; No magic here, but I try to define the color (background and foreground/textcolor) of this button. I read in the Apple forum somewhere that the button changes the color if I change the navigationbar to the same color, well despite the fact that I do not get this to work either (for testing) I do not want to touch the navigationbr itself, just the button. Since this button is already predefined I am not sure how to handle this. Do I need to overwrite the button with my own definition or can I just simply apply a new style (if so how ?) Thx
