  • Question about MySQLdb, OS X 10.5, and authentication

    - by timpone
    I'm a noob at Python and have been having problems with MySQLdb and OS X Leopard 10.5. I have a php app that is doing db access just fine with pdo but also want to access with Python. When I use the same credentials with MySQLdb as php, I get the following error: File "build/bdist.macosx-10.5-i386/egg/MySQLdb/connections.py", line 188, in __init__ _mysql_exceptions.OperationalError: (1045, "Access denied for user 'arc_db'@'localhost' (using password: YES)") The authentication piece works fine on my ubuntu server (installed via apt-get) implying that it is something specific to my OS X MySQLdb install. Looking at some postings, I thought it would be my local build of MySQLdb which seems to be problematic with OS X. But I am able to import fine: Python 2.5.1 (r251:54863, Feb 6 2009, 19:02:12) [GCC 4.0.1 (Apple Inc. build 5465)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import MySQLdb >>> Also, wanting to create a positive, I am able to access and return results from a database tilted test_something (which presumably bypasses the MySQL's authtentication - not sure exactly how though). Trying to figure out a little more what is going on, I turn on logging for mysql and get the following (added my own comments): 100609 19:09:45 3 Connect Access denied for user 'arc_db'@'localhost' (using password: YES) //not worked 100609 19:10:02 4 Connect arc_db@localhost on arc_development //did work I'm not really sure what the 3 or 4 means but presumably a sucess or failue. So, I guess what would be the next step? Am I doing some obvious stupid python mistake (very likely)? Is there a better way for me to prove that this should / can be working? Is there any way to determine what MySQLdb is sending exactly in its authentication message to MySQL? thanks

  • Selecting a Java framework for large application w/ only ONE user

    - by Bijan
    I am building a large application that will be hosted on an AWS server. I'm trying to select a web framework for assisting me with code organization, template design, and generally presentation aspects. Here are some points of consideration: Require security/login/user authentication. I may add the ability in the future to allow more than just an administrator to access the web app, but it is not a public facing website. AJAX support would be helpful. There are a couple widgets that I don't want to recreate. One is a tree object, where the user can expand/contract items in the list, can create new branches, add/edit objects. This would be better off in some dynamic view rather than all done in ugly html. Generally, this is just to provide the application with a face for control, management, and monitoring. Having an easier time adding buttons, CSS, AJAX widgets are great additions though, but not the primary purpose. I'm considering: Wicket Spring Seam GWT Stripe and the list goes on, as I'm sure you all know. I originally planned on using GWT, but then started to feel that GWT didn't cover my primary needs. I could be wrong about this, but there seems to be a lot of support for GWT AND Wicket/Spring. All of this 'getting lost in java frameworks' got me thinking outside the java realm for a framework that would suit my needs that was a clear option, like: JRuby/Rails Jython/Django Groovy/Grails Guice (just throwing this in there... I don't clearly understand the main purposes of all these frameworks. It doesn't seem like DInjection is something I need for a single purpose application) Thanks as always. This community makes Googling for esoteric programming information an order of magnitude better.

  • HTTP Error: 400 when sending msmq message over http

    - by dontera
    I am developing a solution which will utilize msmq to transmit data between two machines. Due to the seperation of said machines, we need to use HTTP transport for the messages. In my test environment I am using a Windows 7 x64 development machine, which is attempting to send messages using a homebrew app to any of several test machines I have control over. All machines are either windows server 2003 or server 2008 with msmq and msmq http support installed. For any test destination, I can use the following queue path name with success: FORMATNAME:DIRECT=TCP:[machine_name_or_ip]\private$\test_queue But for any test destination, the following always fails FORMATNAME:DIRECT=HTTP://[machine_name_or_ip]/msmq/private$/test_queue I have used all permutations of machine names/ips available. I have created mappings using the method described at this blog post. All result in the same HTTP Error: 400. The following is the code used to send messages: MessageQueue mq = new MessageQueue(queuepath); System.Messaging.Message msg = new System.Messaging.Message { Priority = MessagePriority.Normal, Formatter = new XmlMessageFormatter(), Label = "test" }; msg.Body = txtMessageBody.Text; msg.UseDeadLetterQueue = true; msg.UseJournalQueue = true; msg.AcknowledgeType = AcknowledgeTypes.FullReachQueue | AcknowledgeTypes.FullReceive; msg.AdministrationQueue = new MessageQueue(@".\private$\Ack"); if (SendTransactional) mq.Send(msg, MessageQueueTransactionType.Single); else mq.Send(msg); Additional Information: in the IIS logs on the destination machines I can see each message I send being recorded as a POST with a status code of 200. I am open to any suggestions.

  • Vote on Pros and Cons of Java HTML to XML cleaners

    - by George Bailey
    I am looking to allow HTML emails (and other HTML uploads) without letting in scripts and stuff. I plan to have a white list of safe tags and attributes as well as a whitelist of CSS tags and value regexes (to prevent automatic return receipt). I asked a question: Parse a badly formatted XML document (like an HTML file) I found there are many many ways to do this. Some systems have built in sanitizers (which I don't care so much about). This page is a very nice listing page but I get kinda lost http://java-source.net/open-source/html-parsers It is very important that the parsers never throw an exception. There should always be best guess results to the parse/clean. It is also very important that the result is valid XML that can be traversed in Java. I posted some product information and said Community Wiki. Please post any other product suggestions you like and say Community Wiki so they can be voted on. Also any comments or wiki edits on what part of a certain product is better and what is not would be greatly appreciated. (for example,, speed vs accuracy..) It seems that we will go with either jsoup (seems more active and up to date) or TagSoup (compatible with JDK4 and been around awhile). A +1 for any of these products would be if they could convert all style sheets into inline style on the elements.

  • General Drools Question

    - by El Guapo
    For the last few months my company has been using a product from a company called Informatica (previously AgentLogic) called RulePoint. This product has proven itself very easy to use with a well-developed and easy-to-use SDK for customization. The way we use the product for CEP is fairly trivial, we have 2 sources which we monitor for our rule data, the first being a JMS Queue, the second being a Jabber IM account. The product runs on any java-based application server (WebLogic, Tomcat, etc) and runs just about flawlessly. Last week my boss says, "Hey, I've heard that we may be able to do the same thing we are doing with RulePoint with an open-source product called Drools. Check it out and let me know what you think." I've heard of people using Drools for flow-based operations (validation, etc), however, I've never heard of anyone using their CEP product (Fusion) in practice. So, being the diligent worker, I have undertaken this task. I've downloaded all the files (version 5.0) and accompanying documentation and have started to read. I've read through just about all the docs and run most of the examples, but I still don't really see HOW drools works for CEP. While there are examples for using Data (or Facts, I guess) from JMS, I don't see how this thing stays "running", continuously monitoring a queue until the application is actually stopped. RulePoint pretty must just sits and listens, however, Drools seems to not. I could probably write a full-blown command-line application for our needs, however, I was hoping to leverage some of the benefits of using a application server provides. I guess I'm looking for some good tutorials or an example of how someone is using Drools and CEP in production. Thanks in advanced for any information, advice you may be able to provide.

  • How to determine the (natural) language of a document?

    - by Robert Petermeier
    I have a set of documents in two languages: English and German. There is no usable meta information about these documents, a program can look at the content only. Based on that, the program has to decide which of the two languages the document is written in. Is there any "standard" algorithm for this problem that can be implemented in a few hours' time? Or alternatively, a free .NET library or toolkit that can do this? I know about LingPipe, but it is Java Not free for "semi-commercial" usage This problem seems to be surprisingly hard. I checked out the Google AJAX Language API (which I found by searching this site first), but it was ridiculously bad. For six web pages in German to which I pointed it only one guess was correct. The other guesses were Swedish, English, Danish and French... A simple approach I came up with is to use a list of stop words. My app already uses such a list for German documents in order to analyze them with Lucene.Net. If my app scans the documents for occurrences of stop words from either language the one with more occurrences would win. A very naive approach, to be sure, but it might be good enough. Unfortunately I don't have the time to become an expert at natural-language processing, although it is an intriguing topic.

  • Debugging MinGW program with gdb on Windows, not terminating at assert failure

    - by devil
    How do I set up gdb on window so that it does not allow a program with assertion failure to terminate? I intend to check the stack trace and variables in the program. For example, running this test.cpp program compiled with MinGW 'g++ -g test.cpp -o test' in gdb: #include <cassert> int main(int argc, char ** argv) { assert(1==2); return 0; } Gives: $ gdb test.exe GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

  • singleton pattern in Windows Activation Service

    - by Joshua
    Hello I have a few WCF services that are currently being self hosted, in a very basic NT Service. I want to expand my application to add provisioning of WCF Services, and updates, as well as isolation (I want each WCF Service to be in its own AppDomain). These WCF Services contain logic that needs to be run on a regular basis, pinging the database, and getting information from external devices so that when a request comes in the data is readily available. I'm thinking about trying out Windows Activation Service, because i really like the provisioning, and isolation that comes with a managed services infrastructure. If I didn't use WAS I would essentially have to write the same code myself. From what I understand though WAS does not really support the model of having a service that is running before someone actually calls a method on the service. the article I read here MSDN Article Link states "That means in essence that out-of-the-box WAS hosting is not something that is really suited for sessionful or singleton services. It is more suitable for stateless per-call services." it does say that "Out of the box" so I'm wondering if anyone has used WAS to host a WCF service that really behaves more like an NT Service (starting and stopping independantly of having a method called upon it). Or any other ideas would be great. I was planning on writting this infrastructure myself, to host WCF services in a custom ServiceHost, and put their execution in a seporate AppDomain, as well as allow for provision of these services after initial installation, along with updates. However, I would MUCH MUCH MUCH rather not own that code if I don't have to. thanks Joshua

  • Why does my J2ME DateField not display the correct date?

    - by olly
    I am storing values and date values in a record store. I have my date field set up like this: StartDate = new DateField("Start Date ", DateField.DATE); cal1 = Calendar.getInstance(); cal1.set(Calendar.YEAR, 2009); cal1.set(Calendar.MONTH, 0); cal1.set(Calendar.DAY_OF_MONTH, 1); StartDate.setDate(cal1.getTime()); and I save the date as a string as follows: strStartDate = cal1.get(cal1.DAY_OF_MONTH) + "/" + (cal1.get(cal1.MONTH) + 1) + "/" + cal1.get(cal1.YEAR); String detailsToAdd = strStartDate (I have shortened the code.) Now, I want to be able to edit the date at a future stage. However, I need the code to be able to do this. So far I have: EStartDate = new DateField("Start Date ", DateField.DATE); I had to change the name of the DateField box as this was conflicting with other things. I basically need to be able to show the selected record's date attribute. I currently have the other information displayed. I just need to be able to show the correct date. When I run the program the date field says <date>. Any help will be nice

  • Precompiled headers question

    - by Kotti
    Hello! I am right now reorganizing my project and what recently was a simple application now became a pair of C++ projects - static library and real application. I would like to share one precompiled header between two projects, but face some troubles with setting up the .pdb file paths. Assume my first project is called Library and builds it's .lib file with a corresponding Library.pdb file. Now, the second project is called Application and builds everything into the same folder (.exe and another Application.pdb file). Right now my both projects create their own precompiled headers file (Library.pch and Application.pch) based on one actual header file. It works, but I think it's a waste of time and I also think there should be a way to share one precompiled header between two projects. If in my Application project I try to set the Use Precompiled Header (/Yu) option and set it to Library.pch, it wouldn't work, because of the following error: error C2858: command-line option 'program database name "Application.pdb" inconsistent with precompiled header, which used "Library.pdb". So, does anyone know some trick or way to share one precompiled header between two projects preserving proper debug information?

  • How do I check if output stream of a socket is closed?

    - by Roman
    I have this code: public void post(String message) { output.close(); final String mess = message; (new Thread() { public void run() { while (true) { try { output.println(mess); System.out.println("The following message was successfully sent:"); System.out.println(mess); break; } catch (NullPointerException e) { try {Thread.sleep(1000);} catch (InterruptedException ie) {} } } } }).start(); } As you can see I close the socket in the very beginning of the code and then try to use it to send some information to another computer. The program writes me "The following message was successfully sent". It means that the NullPointerException was not thrown. So, does Java throw no exception if it tries to use a closed output stream of a socket? Is there a way to check if a socket is closed or opened? ADDED I initialize the socket in the following way: clientSideSocket = new Socket(hostname,port); PrintWriter out = new PrintWriter(clientSideSocket.getOutputStream(), true); browser.output = out;

  • User roles - why not store in session?

    - by Phil
    I'm porting an ASP.NET application to MVC and need to store two items relating to an authenitcated user: a list of roles and a list of visible item IDs, to determine what the user can or cannot see. We've used WSE with a web service in the past and this made things unbelievably complex and impossible to debug properly. Now we're ditching the web service I was looking foward to drastically simplifying the solution simply to store these things in the session. A colleague suggested using the roles and membership providers but on looking into this I've found a number of problems: a) It suffers from similar but different problems to WSE in that it has to be used in a very constrained way maing it tricky even to write tests; b) The only caching option for the RolesProvider is based on cookies which we've rejected on security grounds; c) It introduces no end of complications and extra unwanted baggage; All we want to do, in a nutshell, is store two string variables in a user's session or something equivalent in a secure way and refer to them when we need to. What seems to be a ten minute job has so far taken several days of investigation and to compound the problem we have now discovered that session IDs can apparently be faked, see http://blogs.sans.org/appsecstreetfighter/2009/06/14/session-attacks-and-aspnet-part-1/ I'm left thinking there is no easy way to do this very simple job, but I find that impossible to believe. Could anyone: a) provide simple information on how to make ASP.NET MVC sessions secure as I always believed they were? b) suggest another simple way to store these two string variables for a logged in user's roles etc. without having to replace one complex nightmare with another as described above? Thank you.

  • SHA function issues

    - by Damian James
    I have this php code from my login.php if (isset($_POST['logIn'])) { $errmsg = ""; $logname = mysqli_real_escape_string($dbc, trim($_POST['usernameIn'])); $logpassword = mysqli_real_escape_string($dbc, trim($_POST['passwordIn'])); $query = "SELECT user_id, username FROM members WHERE username = '$logname' AND password = SHA('$logpassword')"; $data = mysqli_query($dbc, $query); if (mysqli_num_rows($data) == 1) { $row = mysqli_fetch_array($data); setcookie('user_id', $row['user_id'], time() + (60 * 60 * 24 * 30)); //expires after 30 days setcookie('username', $row['username'], time() + (60 * 60 * 24 * 30)); $home = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . '/index.php'; header('Location: ' . $home); } else { $errmsg = '<p class="errormsg">Username or password is incorrect.</p>'; } } And for some reason, it always ends up setting $errmsg in the else statement. I am sure that I'm entering information (username,password) that is correct and exists in the database. I insert my values (from a signup script) using this query: $query = "INSERT INTO members (username, password, email) VALUES ('$username', SHA('$password'), '$email')"; Anyone see the problem with this script? Thanks!

  • Using the MVVM Light Toolkit to make Blendable applications

    - by Dave
    A while ago, I posted a question regarding switching between a Blend-authored GUI and a Visual Studio-authored one. I got it to work okay by adding my Blend project to my VS2008 project and then changing the Startup Application and recompiling. This would result in two applications that had completely different GUIs, yet used the exact same ViewModel and Model code. I was pretty happy with that. Now that I've learned about the Laurent Bugnion's MVVM Light Toolkit, I would really like to leverage his efforts to make this process of supporting multiple GUIs for the same backend code possible. The question is, does the toolkit facilate this, or am I stuck doing it my previous way? I've watched his video from MIX10 and have read some of the articles about it online. However, I've yet to see something that indicates that there is a clean way to allow a user to either dynamically switch GUIs on the fly by loading a different DLL. There are MVVM templates for VS2008 and Blend 3, but am I supposed to create both types of projects for my application and then reference specific files from my VS2008 solution? UPDATE I re-read some information on Laurent's site, and seemed to have forgotten that the whole point of the template was to allow the same solution to be opened in VS2008 and Blend. So anyhow, with this new perspective it looks like the templates are actually intended to use a single GUI, most likely designed entirely in Blend (with the convenience of debugging through VS2008), and then be able to use two different ViewModels -- one for design-time, and one for runtime. So it seems to me like the answer to my question is that I want to use a combination of my previous solution, along with the MVVM Light Toolkit. The former will allow me to make multiple, distinct GUIs around my core code, while the latter will make designing fancy GUIs in Blend easier with the usage of a design-time ViewModel. Can anyone comment on this?

  • Use Google Calendar UI but showing only filtered events

    - by Edwin
    I have just started using Google Calendar API (using Python client). I'm basically developing a web app for a school with Django. What I'd like to achieve is something like this: To make things simple for now, I have 1 Google account and all events will be created in the calendar under that account (this is the school calendar). The calendar will be made public. When a class is created by a teacher, the class schedule will be automatically added as an event in the Google Calendar. When a student logs in, he can see the school calendar, showing only schedules from the classes that he's registered in. I think I can filter the calendar feeds to show only class schedules that a student is registered in using Google Data API. The problem is, how can I display Google Calendar on my web app using Google Calendar UI to show only those filtered events? I can use Google Calendar UI with the provided embeddable HTML snippet, but I can't control/filter events with that (i.e. all events in the school calendar will be displayed). Or perhaps I'm missing something? I read the Data API guide and the Publishing tool doc but I can't seem to find this information. THanks in advance!

  • Perform case-insensitive lookup on an Array in MongoDB?

    - by Hal
    So, I've decided to get my feet wet with MongoDB and love it so far. It seems very fast and flexible which is great. But, I'm still going through the initial learning curve and as such, I'm spending hours digging for info on the most basic things. I've search throughout the MongoDB online documentation and have spent hours Googling through pages without any mention of this. I know Mongo is still quite new (v1.x) so it explains why there isn't much information yet. I've even trying looking for books on Mongo without much luck. So yes, I've tried to RTFM with no luck, so, now I turn to you. I have an Array of various Hashtags nested in each document (ie: #apples, #oranges, #Apples, #APPLES) and I would like to perform a case-insensitive find() to access all the documents containing apples in any case. It seems that find does support some regex with /i, but I can't seem to get this working either. Anyway, I hope this is a quick answer for someone. Here's my existing call in PHP which is case sensitive: $cursor = $collection->find(array( "hashtags" => array("#".$keyword)))->sort(array('$natural' => -1))->limit(10); Help?

  • Difficulty setting ArrayList to java.sql.Blob to save in DB using hibernate

    - by me_here
    I'm trying to save a java ArrayList in a database (H2) by setting it as a blob, for retrieval later. If this is a bad approach, please say - I haven't been able to find much information on this area. I have a column of type Blob in the database, and Hibernate maps to this with java.sql.Blob. The code I'm struggling with is: Drawings drawing = new Drawings(); try { ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = null; oos = new ObjectOutputStream(bos); oos.writeObject(plan.drawingPane21.pointList); byte[] buff = bos.toByteArray(); Blob drawingBlob = null; drawingBlob.setBytes(0, buff); drawing.setDrawingObject(drawingBlob); } catch (Exception e){ System.err.println(e); } The object I'm trying to save into a blob (plan.drawingPane21.pointList) is of type ArrayList<DrawingDot>, DrawingDot being a custom class implementing Serializable. My code is failing on the line drawingBlob.setBytes(0, buff); with a NullPointerException. Help appreciated.

  • Error displaying a WinForm in Design mode with a custom control on it.

    I have a UserControl that is part of a Class library. I reference this project from my solution. This adds a control from the referenced project to my toolbox. I add tghe control to a form. Everything looks good, I compile all and run. Perfect... But when I close the .frm with the control on it and re-open it, I get this error. The code continues to run.

  • C# - Alternative to System.Time.Timer, to call a function at a specific time.

    - by Fábio Antunes
    Hello everybody. I want to call a specific function on my C# application at a specific time. At first i thought about using a Timer (System.Time.Timer), but that soon became impossible to use. Why? Simple. The Timer Class requires a Interval in milliseconds, but considering that i might want the function to be executed, lets says in a week that would mean: 7 Days = 168 hours; 168 Hours = 10,080 minutes; 10,080 Minutes = 6,048,000 seconds; 6,048,000 Seconds = 6,048,000,000 milliseconds; So the Interval would be 6,048,000,000; Now lets remember that the Interval accepted data type is int, and as we know int range goes from -2,147,483,648 to 2,147,483,647. That makes Timer useless in this case once we cannot set a Interval bigger that 2,147,483,647 milliseconds. So i need a solution where i could specify when the function should be called. Something like this: solution.ExecuteAt = "30-04-2010 15:10:00"; solution.Function = "functionName"; solution.Start(); So when the System Time would reach "30-04-2010 15:10:00" the function would be executed in the application. How can this problem be solved? Thanks just by taking the time to read my question. But if you could provide me with some help i would be most grateful. Additional Info: What these functions will do? Getting climate information and based on that info: Starting / Shutting down other Applications (most of them Console Based); Sending custom Commands to those Console Applications; Power down, Rebooting, Sleep, Hibernate the computer; And if possible schedule the BIOS to Power Up the Computer;

  • Log4net Logging Problem : Very simple file appender logging not working

    - by contactmatt
    Here's my web.config information <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net> <root> <level value="ALL" /> </root> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="c:\temp\log-file.txt" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="1MB" /> <staticLogFileName value="true" /> <layout type="log4net.Layout.SimpleLayout" /> </appender> </log4net> ... Here's the code that initalizes the logger protected void SendMessage() { log4net.Config.XmlConfigurator.Configure(); ILog log = LogManager.GetLogger(typeof(Contact)); ... log.Info("here we go!"); log.Debug("debug afasf"); ... } it doesn't work, no matter what I seem to do. I am referencing the 'log4net.dll' correctly, and by debugging the application i can see that the log object is getting initiated properly. This is a asp.net 3.5 framework web project. Any ideas/suggestions? I thought originally this error may be due to a file write permission constraint, but that doesn't seem to be the case (or so I think).

  • Asp.net Login Status Question: It Aint Working

    - by contactmatt
    I'm starting to use Role Management in my website, and I'm current following along on the tutorial from http://www.asp.net/Learn/Security/tutorial-02-vb.aspx . I'm having a problem with the asp:LoginStatus control. It is not telling me that I am currently logged in after a successful login. This can't be true because after successfully logging in, my LoggedInTemplate is shown. The username and passwords are simply stored in a array. Heres the Login.aspx page code. Protected Sub btnLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs) _ Handles btnLogin.Click ' Three valid username/password pairs: Scott/password, Jisun/password, and Sam/password. Dim users() As String = {"Scott", "Jisun", "Sam"} Dim passwords() As String = {"password", "password", "password"} For i As Integer = 0 To users.Length - 1 Dim validUsername As Boolean = (String.Compare(txtUserName.Text, users(i), True) = 0) Dim validPassword As Boolean = (String.Compare(txtPassword.Text, passwords(i), False) = 0) If validUsername AndAlso validPassword Then FormsAuthentication.RedirectFromLoginPage(txtUserName.Text, chkRemember.Checked) End If Next ' If we reach here, the user's credentials were invalid lblInvalid.Visible = True End Sub Here is the content place holder on the master page specifically designed to hold Login Information. On successfull login, the page is redirected to '/Default.aspx', and the LoggedIn Template below is shown...but the status says Log In. <asp:ContentPlaceHolder Id="LoginContent" runat="server"> <asp:LoginView ID="LoginView1" runat="server"> <LoggedInTemplate> Welcome back, <asp:LoginName ID="LoginName1" runat="server" />. </LoggedInTemplate> <AnonymousTemplate> Hello, stranger. </AnonymousTemplate> </asp:LoginView> <br /> <asp:LoginStatus ID="LoginStatus1" runat="server" LogoutAction="Redirect" LogoutPageUrl="~/Logout.aspx" /> </asp:ContentPlaceHolder> Forms authentication is enabled. I'm not sure what to do about this :o.

  • Synchronize DataGrid and DataForm in Silverlight 3

    - by SpiralGray
    I've been banging my head against the wall for a couple of days on this and it's time to ask for help. I've got a DataGrid and DataForm on the same UserControl. I'm using an MVVM approach so there is a single ViewModel for the UserControl. That ViewModel has a couple of properties that are relevant to this discussion: public ObservableCollection<VehicleViewModel> Vehicles { get; private set; } public VehicleViewModel SelectedVehicle { get { return selectedVehicle; } private set { selectedVehicle = value; OnPropertyChanged( "SelectedVehicle" ); } } In the XAML I've got the DataGrid and DataForm defined as follows: <data:DataGrid SelectionMode="Single" ItemsSource="{Binding Vehicles}" SelectedItem="{Binding SelectedVehicle, Mode=TwoWay}" AutoGenerateColumns="False" IsReadOnly="True"> <dataFormToolkit:DataForm CurrentItem="{Binding SelectedVehicle}" /> So as the SelectedItem changes on the DataGrid it should push that change back to the ViewModel and when the ViewModel raises the OnPropertyChanged the DataForm should refresh itself with the information for the newly-selected VehicleViewModel. However, the setter for SelectedVehicle is never being called and in the Output window of VS I'm seeing the following error: System.Windows.Data Error: ConvertBack cannot convert value 'xxxx.ViewModel.VehicleViewModel' (type 'xxxx.ViewModel.VehicleViewModel'). BindingExpression: Path='SelectedVehicle' DataItem='xxxx.ViewModel.MainViewModel' (HashCode=31664161); target element is 'System.Windows.Controls.DataGrid' (Name=''); target property is 'SelectedItem' (type 'System.Object').. System.MethodAccessException: xxxx.ViewModel.MainViewModel.set_SelectedVehicle(xxxx.ViewModel.VehicleViewModel) It sounds like it's having a problem converting from a VehicleViewModel to an object (or back again), but I'm confused as to why that would be (or even if I'm on the right track with that assumption). Each row/item in the DataGrid should be a VehicleViewModel (because the ItemsSource is bound to an ObservableCollection of that type), so when the SelectedItem changes it should be dealing with an instance of VehicleViewModel. Any insight would be appreciated.
