• Why is there no assertError() function in FlexUnit?

  - by lorennorman

  It seems that most XUnit testing frameworks provide assertions for the times when you want to assert that a given operation will thrown an exception (or an Error in AS3 parlance.) Is there some "standard" way of doing this that I am overlooking, which would explain the absence of an assertError() assertion included with FlexUnit? I know HOW to implement such a thing, and I will probably add it to my FlexUnit (go open source!), but it seems like such a glaring omission that I'm left wondering if I'm just doing it wrong. Anyone have thoughts on this?

• Calling Facebook API without authenticating user/"connecting"

  - by Andy

  Hi, I am working with facebook's API and I want to call the links.prevew method. http://wiki.developers.facebook.com/index.php/Links.preview Is it possible to call this method without having my user authenticate or "connect"? For example, not all of my users have hooked up their facebook accounts to my website, but I still want to use this API method. I am getting the following error: Fatal error: Uncaught Exception: 453: A session key is required for calling this method thrown in /public_html/libs/facebook.php on line 413 But on the wiki it says that the method does not require a session key? If it is not possible to make API calls without such a key, is there anyway I can make calls on behalf of my account or my applications account (rather then a users account)? Any help is appreciated, thanks!

  I am using the Rest Singleton WCF Service temple from the Rest Starter Kit. The temples uses sample item as its sample Item. i am attempting to replace that sample ITem with a custom type from web reference in my ASP.Net project .dll. The types and name spaces are found and i can replace the sample item in the code. when i run the application i get this error: "Exception has been thrown by the target of an invocation." when this line is executed "return new SingletonServiceHost(serviceType, baseAddresses);" <%@ ServiceHost Language="C#" Debug="true" Service="SAUDServices.Service" Factory="SAUDServices.AppServiceHostFactory"%> using System; using System.ServiceModel; using System.ServiceModel.Activation; using Microsoft.ServiceModel.Web.SpecializedServices; using Stretchatyourdesk; namespace SAUDServices { class AppServiceHostFactory : ServiceHostFactory { protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { return new SingletonServiceHost(serviceType, baseAddresses); } } }

• C# ArrayList calling on a constructor class

  - by EvanRyan

  I'm aware that an ArrayList is probably not the way to go with this particular situation, but humor me and help me lose this headache. I have a constructor class like follows: class Peoples { public string LastName; public string FirstName; public Peoples(string lastName, string firstName) { LastName = lastName; FirstName = firstName; } } And I'm trying to build an ArrayList to build a collection by calling on this constructor. However, I can't seem to find a way to build the ArrayList properly when I use this constructor. I have figured it out with an Array, but not an ArrayList. I have been messing with this to try to build my ArrayList: ArrayList people = new ArrayList(); people[0] = new Peoples("Bar", "Foo"); people[1] = new Peoples("Quirk", "Baz"); people[2] = new Peopls("Get", "Gad"); My indexing is apparently out of range according to the exception I get.

• Unkillable console windows

  - by rep_movsd

  I'm developing an OpenGL based 2d simulation with GLUT under Visual C++ 2008, sometimes when I have an assert() or unhandled exception and break into the debugger, the GLUT display window closes, but the console window remains open.They just cant be killed!!! They do not show up with Task manager, Process Explorer or any other tool, I cannot find the window handle using the Spy++ tool either. Worst thing is they prevent my system (Windows XP) from shutting down, I have to manually poweroff (and of course I have to run chkdsk on my drives and invariably it finds and fixes minor errors after bad shutdowns) Has anyone come across such an issue?

• Ruby socket server thread question: how to send to all clients?

  - by Paul

  I'm making a TCP socket server(ruby). A thread is created for each connected client. At some point I try to send data to all connected clients. The thread aborts on exception while trying.(ruby 1.8.7) require 'socket' # I test it home right now server = TCPServer.new('localhost', 12345); while(session = server.accept) #Here is the thread being created Thread.new(session) do |s| while(msg = s.gets) #Here is the part that causes the error Thread.list.each { |aThread| if aThread != Thread.current #So what I want it to do is to echo the message from one client to all others #But for some reason it doesn't, and aborts on the following string aThread.print "#{msg}\0" end } end end Thread.abort_on_exception = true end What am I doing wrong?

• telling java to accept self-signed ssl certificate

  - by Nikita Rybak

  It looks like a standard question, but I couldn't find clear directions anywhere. I have java code trying to connect server with probably self-signed (or expired) certificate. It gives something like this [HttpMethodDirector] I/O exception (javax.net.ssl.SSLHandshakeException) caught when processing request: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target As I understand, I have to play around with keytool and tell java that it's ok to allow this connection. But all comments I've found assume I'm fully proficient with keytool, like "generate private key for server and import it into keystore". And I'm not. Is there anybody who could post detailed instructions? I'm running unix, so bash script would be best. Not sure if it's important, but code executed in jboss. Thanks a lot!

• Fluent NHib causing visual studio 2010 hanging at runtime

  - by Berryl

  Just installed and migrated a 2008 solution on Vista ultimate 64 and .net 4.0. Everything builds and tests run surprisingly well but I got the hang description below while trying to run the app under SQLite. It turns out that the hang has got something to do when the call is made for FNH to build the session factory during a run, the only feedback I get is that the database wasn't configure properly without any inner exception. The strange part is that the exact code works perfectly under tests. Any clues? Description: A problem caused this program to stop interacting with Windows. Problem signature: Problem Event Name: AppHangB1 Application Name: devenv.exe Application Version: 10.0.30319.1 Application Timestamp: 4ba1fab3 Hang Signature: b9ed Hang Type: 6152 OS Version: 6.0.6002.2.2.0.256.1 Locale ID: 1033 Additional Hang Signature 1: 005de38e6b4bb3afd8e147932c6431cc Additional Hang Signature 2: d54c Additional Hang Signature 3: 05f671c8289bf8dd31e6ccfe265baa77 Additional Hang Signature 4: 784c Additional Hang Signature 5: c8207f54dadf3eb38dfcf1ae152f4229 Additional Hang Signature 6: ff83 Additional Hang Signature 7: 220932152f3f04fffb6ca3abf15e6dc6

• How to create a server control on another ASPX file

  - by salvationishere

  I am developing a C#/SQL ASP.NET web application in VS 2008. Currently, I am transferring control from one ASPX file to another: if (uploadFile.PostedFile.ContentLength > 0) { inputfile = System.IO.File.ReadAllText(path); Context.Items["Message"] = inputfile; //Page1 Server.Transfer("DataMatch.aspx"); //Page1 } However, it fails on this Server.Transfer line after inserting runat="server" in the DataMatch.aspx file to the Table element like so: <table width="50%" id="tMain" runat="server"> But after making this a server control, I rebuilt it and now when I run this app it gives me exception: Error executing child request for DataMatch.aspx But I need this table to be a server control so I can make it invisible programmatically if a certain condition occurs. How else can I programmatically make this table invisible?

• Out of Memory on Update or Delete of Service Reference

  - by Kelly

  I have a Service Reference for a WCF project that has just over a hundred endpoints in my ServiceHost web.config. Every time I attempt to update or delete the Service Reference, it fails with an out of memory exception. I am running Vista Ultimate SP2 64-bit with 8GB RAM. I can work around it by going outside the project and deleting the Service References folder, then coming back in and re-adding the Reference. Is this the only workaround that you know of? Thanks!

If "ApplyPropertyChanges()" is removed, it adds a User. What orders should these methods be called? I don't need to do them separately right? Thanks.

• ClickOnce: How do I pass a querystring value to my app *through the installer*?

  - by Timothy Khouri

  My company currently builds separate MSI's for all of our clients, even though the app is 100% the same across the board (with a single exception, an ID in the app.config). I would like to show them that we can publish in once place with ClickOnce, and simply add a query string parameter for each client's installer. Example: http://mysite.com/setup.exe?ID=1234-56-7890 The issue that I'm having is that the above ("ID=1234...") is not being passed along to the "myapplication.application". What is happening instead is, the app is being installed successfully, and it is running the first time with an activation context, but the "ActivationUri" does not contain any query string values. Is there a way to pass query string values FROM THE INSTALLER URL to the application's launch URL? If so, how?

• Returning a JSON view in combination with a boolean

  - by Rody van Sambeek

  What i would like to accomplish is that a partiel view contains a form. This form is posted using JQuery $.post. After a successfull post javascript picks up the result and uses JQuery's html() method to fill a container with the result. However now I don't want to return the Partial View, but a JSON object containing that partial view and some other object (Success - bool in this case). I tried it with the following code: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(int id, Item item) { if (ModelState.IsValid) { try { // ... return Json(new { Success = true, PartialView = PartialView("Edit", item) }); } catch(Exception ex) { // ... } } return Json(new { Success = false, PartialView = PartialView("Edit", item) }); } However I don't get the HTML in this JSON object and can't use html() to show the result. I tried using this method to render the partial as Html and send that. However this fails on the RenderControl(tw) method with a: The method or operation is not implemented.

• Can a http server detect that a client has cancelled their request?

  - by Nick Retallack

  My web app must process and serve a lot of data to display certain pages. Sometimes, the user closes or refreshes a page while the server is still busy processing it. This means the server will continue to process data for several minutes only to send it to a client who is no longer listening. Is it possible to detect that the connection has been broken, and react to it? In this particular project, we're using Django and NginX, or Apache. I assumed this is possible because the Django development server appears to react to cancelled requests by printing Broken Pipe exceptions. I'd love to have it raise an exception that my application code could catch. Alternatively, I could register an unload event handler on the page in question, have it do a synchronous XHR requesting that the previous request from this user be cancelled, and do some kind of inter-process communication to make it so. Perhaps if the slower data processing were handed to another process that I could more easily identify and kill, without killing the responding process...
