    - by Malcolm Frexner
    I have this annoying mistake in some of my builds. There is no error in the project, because if I build again, then the problem disappears. The message only appears, when the site is deployed to a Windows 2008 Server. I first thought that it might be an issue with temporary files, but thats not the case. I deployed the build to a different web and the error still appears. The error appears on random actions of the site. Most of the time builds are ok, but each 3rd or 4th build produces runtime errors. I build using a WebdeploymentProject in release mode. Views are precompiled. It's not http://stackoverflow.com/questions/178194/in-asp-net-mvc-i-encounter-an-incorrect-type-error-when-rendering-a-page-with-the, because views have totally different names. How I can debug this problem or how I can get help for this?

  • WCF net.tcp windows service - call duration and calls outstanding increases over time

    - by Brook
    I have a windows service which uses the ServiceHost class to host a WCF Service using the net.tcp binding. I have done some tweaking to the config to throttle sessions as well as number of connections, but it seems that every once in a while my "Calls outstanding" and "Call duration" shoot up and stay up in perfmon. It seems to me I have a leak somewhere, but the code I have is all fairly minimal, I'm relying on ServiceHost to handle the details. Here's how I start my service ServiceHost host = new ServiceHost(type); host.Faulted+=new EventHandler(Faulted); host.Open(); My Faulted event just does the following (more or less, logging etc removed) if (host.State == CommunicationState.Faulted) { host.Abort(); } else { host.Close(); } host = new ServiceHost(type); host.Faulted+=new EventHandler(Faulted); host.Open(); Here's some snippets from my app.config to show some of the things I've tried <runtime> <gcConcurrent enabled="true" /> <generatePublisherEvidence enabled="false" /> </runtime> ......... <behaviors> <serviceBehaviors> <behavior name="Throttled"> <serviceThrottling maxConcurrentCalls="300" maxConcurrentSessions="300" maxConcurrentInstances="300" /> .......... <services> <service name="MyService" behaviorConfiguration="Throttled"> <endpoint address="net.tcp://localhost:49001/MyService" binding="netTcpBinding" bindingConfiguration="Tcp" contract="IMyService"> </endpoint> </service> </services> .......... <netTcpBinding> <binding name="Tcp" openTimeout="00:00:10" closeTimeout="00:00:10" portSharingEnabled="true" receiveTimeout="00:5:00" sendTimeout="00:5:00" hostNameComparisonMode="WeakWildcard" listenBacklog="1000" maxConnections="1000"> <reliableSession enabled="false"/> <security mode="None"/> </binding> </netTcpBinding> .......... <!--for my diagnostics--> <diagnostics performanceCounters="ServiceOnly" wmiProviderEnabled="true" /> There's obviously some resource getting tied up, but I thought I covered everything with my config. I'm only getting about ~150 clients so I don't think I'm coming up against my "300" limit. "Calls per second" stays constant at anywhere from 2-5 calls per second. The service will run for hours and hours with 0-2 "calls outstanding" and very low "call duration" and then eventually it will shoot up to 30 calls oustanding and 20s call duration. Any tips on what might be causing my "calls outstanding" and "call duration" to spike? Where am I leaking? Point me in the right direction?

  • Binding navigation property to RadGrid while using EntityDataSource control

    - by Matrix
    I'm new to Entity Framework and I got stuck in an issue while trying to bind a navigation property (foreign key reference) to a dropdownlist. I have Telerik RadGrid control which gets the data using a EntityDataSource control. Here is the model description: Applications: AppId, AppName, ServerId Servers: ServerId, ServerName The Applicaitons.ServerId is a foreign key reference to Servers.ServerId. The RadGrid lists the applications and allows the user to insert/update/delete an application. I want to show the server names as a dropdownlist in edit mode which I'm not able to. . Here is my aspx code: <telerik:RadGrid ID="gridApplications" runat="server" Skin="Sunset" AllowAutomaticInserts="True" AllowAutomaticDeletes="True" AllowPaging="True" AllowAutomaticUpdates="True" AutoGenerateColumns="False" OnItemCreated="gridApplications_ItemCreated" DataSourceID="applicationsEntityDataSource" Width="50%" OnItemInserted="gridApplications_ItemInserted" OnItemUpdated="gridApplications_ItemUpdated" OnItemDeleted="gridApplications_ItemDeleted" GridLines="None"> <MasterTableView CommandItemDisplay="Top" AutoGenerateColumns="False" DataKeyNames="AppId" DataSourceID="applicationsEntityDataSource"> <RowIndicatorColumn> <HeaderStyle Width="20px" /> </RowIndicatorColumn> <ExpandCollapseColumn> <HeaderStyle Width="20px" /> </ExpandCollapseColumn> <Columns> <telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn" HeaderText="Edit" ItemStyle-Width="10%"> </telerik:GridEditCommandColumn> <telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName="DeleteColumn" ConfirmText="Are you sure you want to delete this application?" ConfirmTitle="Confirm Delete" ConfirmDialogType="Classic" ItemStyle-Width="10%" HeaderText="Delete"> </telerik:GridButtonColumn> <telerik:GridBoundColumn DataField="AppId" UniqueName="AppId" Visible="false" HeaderText="Application Id" ReadOnly="true"> </telerik:GridBoundColumn> <telerik:GridBoundColumn DataField="AppName" UniqueName="AppName" HeaderText="Application Name" MaxLength="30" ItemStyle-Width="40%"> </telerik:GridBoundColumn> <telerik:GridTemplateColumn DataField="ServerId" UniqueName="ServerId" HeaderText="Server Hosted" EditFormColumnIndex="1"> <EditItemTemplate> <asp:DropDownList ID="ddlServerHosted" runat="server" DataTextField="Servers.ServerName" DataValueField="ServerId" Width="40%"> </asp:DropDownList> </EditItemTemplate> </telerik:GridTemplateColumn> </Columns> <EditFormSettings ColumnNumber="2" CaptionDataField="AppId" InsertCaption="Insert New Application" EditFormType="AutoGenerated"> <EditColumn InsertText="Insert record" EditText="Edit application id #:" EditFormColumnIndex="0" UpdateText="Application updated" UniqueName="InsertCommandColumn1" CancelText="Cancel insert" ButtonType="ImageButton"></EditColumn> <FormTableItemStyle Wrap="false" /> <FormTableStyle GridLines="Horizontal" CellPadding="2" CellSpacing="0" Height="110px" Width="110px" /> <FormTableAlternatingItemStyle Wrap="false" /> <FormStyle Width="100%" BackColor="#EEF2EA" /> <FormTableButtonRowStyle HorizontalAlign="Right" /> </EditFormSettings> </MasterTableView> </telerik:RadGrid> <asp:EntityDataSource ID="applicationsEntityDataSource" runat="server" ConnectionString="name=AnalyticsEntities" EnableDelete="True" EntityTypeFilter="Applications" EnableInsert="True" EnableUpdate="True" EntitySetName="Applications" DefaultContainerName="AnalyticsEntities" Include="Servers"> </asp:EntityDataSource> I tried another approach where I replaced the GridTemplateColumn with the following code <telerik:RadComboBox ID="RadComboBox1" DataSourceID="serversEntityDataSource" DataTextField="ServerName" DataValueField="ServerId" AppendDataBoundItems="true" runat="server" > <Items> <telerik:RadComboBoxItem /> </Items> and using a separate EntityDataSource control as follows: <asp:EntityDataSource ID="serversEntityDataSource" runat="server" ConnectionString="name=AnalyticsEntities" EnableDelete="True" EntityTypeFilter="Servers" EnableInsert="True" EnableUpdate="True" EntitySetName="Servers" DefaultContainerName="AnalyticsEntities"> </asp:EntityDataSource> but, I get the following error. Application cannot be inserted. Reason: Entities in 'AnalyticsEntities.Applications' participate in the 'FK_Servers_Applications' relationship. 0 related 'Servers' were found. 1 'Servers' is expected. My question is, how do you bind the navigation property and load the values in the DropDownList/RadComboBox control?

  • TemplateBinding with Converter - what is wrong?

    - by MartyIX
    I'm creating a game desk. I wanted to specify field size (one field is a square) as a attached property and with this data set value of ViewPort which would draw 2x2 matrix (and tile mode would do the rest of game desk). I'm quite at loss what is wrong because the binding doesn't work.

  • Why does WPF Style to show validation errors in ToolTip work for a TextBox but fails for a ComboBox?

    - by Mike B
    I am using a typical Style to display validation errors as a tooltip from IErrorDataInfo for a textbox as shown below and it works fine. <Style TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> But when i try to do the same thing for a ComboBox like this it fails <Style TargetType="{x:Type ComboBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> The error I get in the output window is: System.Windows.Data Error: 17 : Cannot get 'Item[]' value (type 'ValidationError') from '(Validation.Errors)' (type 'ReadOnlyObservableCollection`1'). BindingExpression:Path=(0)[0].ErrorContent; DataItem='ComboBox' (Name='ownerComboBox'); target element is 'ComboBox' (Name='ownerComboBox'); target property is 'ToolTip' (type 'Object') ArgumentOutOfRangeException:'System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.Parameter name: index' Oddly it also attempts to make invalid Database changes when I close the window if I change any ComboBox values (This is also when the binding error occurs)!!! Cannot insert the value NULL into column 'EmpFirstName', table 'OITaskManager.dbo.Employees'; column does not allow nulls. INSERT fails. The statement has been terminated. Simply by commenting the style out everyting works perfectly. How do I fix this? Just in case anyone needs it one of the comboBox' xaml follows: <ComboBox ItemsSource="{Binding Path=Employees}" SelectedValuePath="EmpID" SelectedValue="{Binding Path=SelectedIssue.Employee2.EmpID, Mode=OneWay, ValidatesOnDataErrors=True}" ItemTemplate="{StaticResource LastNameFirstComboBoxTemplate}" Height="28" Name="ownerComboBox" Width="120" Margin="2" SelectionChanged="ownerComboBox_SelectionChanged" /> <DataTemplate x:Key="LastNameFirstComboBoxTemplate"> <TextBlock> <TextBlock.Text> <MultiBinding StringFormat="{}{1}, {0}" > <Binding Path="EmpFirstName" /> <Binding Path="EmpLastName" /> </MultiBinding> </TextBlock.Text> </TextBlock> </DataTemplate> SelectionChanged: (I do plan to implement commanding before long but, as this is my first WPF project I have not gone full MVVM yet. I am trying to take things in small-medium sized bites) // This is done this way to maintain the DataContext Integrity // and avoid an error due to an Object being "Not New" in Linq-to-SQL private void ownerComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e) { Employee currentEmpl = ownerComboBox.SelectedItem as Employee; if (currentEmpl != null && currentEmpl != statusBoardViewModel.SelectedIssue.Employee2) { statusBoardViewModel.SelectedIssue.Employee2 = currentEmpl; } }

  • Python: combine logging and wx so that logging stream is redirectet to stdout/stderr frame

    - by Uwe
    Here's the thing: I'm trying to combine the logging module with wx.App()'s redirect feature. My intention is to log to a file AND to stderr. But I want stderr/stdout redirected to a separate frame as is the feature of wx.App. My test code: import logging import wx class MyFrame(wx.Frame): def __init__(self): self.logger = logging.getLogger("main.MyFrame") wx.Frame.__init__(self, parent = None, id = wx.ID_ANY, title = "MyFrame") self.logger.debug("MyFrame.__init__() called.") def OnExit(self): self.logger.debug("MyFrame.OnExit() called.") class MyApp(wx.App): def __init__(self, redirect): self.logger = logging.getLogger("main.MyApp") wx.App.__init__(self, redirect = redirect) self.logger.debug("MyApp.__init__() called.") def OnInit(self): self.frame = MyFrame() self.frame.Show() self.SetTopWindow(self.frame) self.logger.debug("MyApp.OnInit() called.") return True def OnExit(self): self.logger.debug("MyApp.OnExit() called.") def main(): logger_formatter = logging.Formatter("%(name)s\t%(levelname)s\t%(message)s") logger_stream_handler = logging.StreamHandler() logger_stream_handler.setLevel(logging.INFO) logger_stream_handler.setFormatter(logger_formatter) logger_file_handler = logging.FileHandler("test.log", mode = "w") logger_file_handler.setLevel(logging.DEBUG) logger_file_handler.setFormatter(logger_formatter) logger = logging.getLogger("main") logger.setLevel(logging.DEBUG) logger.addHandler(logger_stream_handler) logger.addHandler(logger_file_handler) logger.info("Logger configured.") app = MyApp(redirect = True) logger.debug("Created instance of MyApp. Calling MainLoop().") app.MainLoop() logger.debug("MainLoop() ended.") logger.info("Exiting program.") return 0 if (__name__ == "__main__"): main() Expected behavior is: - a file is created named test.log - the file contains logging messages with level DEBUG and INFO/ERROR/WARNING/CRITICAL - messages from type INFO and ERROR/WARNING/CRITICAL are ether shown on the console or in a separate frame, depending on where they are created - logger messages that are not inside MyApp or MyFrame are displayed at the console - logger messages from inside MyApp or MyFrame are shown in a separate frame Actual behavior is: - The file is created and contains: main INFO Logger configured. main.MyFrame DEBUG MyFrame.__init__() called. main.MyFrame INFO MyFrame.__init__() called. main.MyApp DEBUG MyApp.OnInit() called. main.MyApp INFO MyApp.OnInit() called. main.MyApp DEBUG MyApp.__init__() called. main DEBUG Created instance of MyApp. Calling MainLoop(). main.MyApp DEBUG MyApp.OnExit() called. main DEBUG MainLoop() ended. main INFO Exiting program. - Console output is: main INFO Logger configured. main.MyFrame INFO MyFrame.__init__() called. main.MyApp INFO MyApp.OnInit() called. main INFO Exiting program. - No separate frame is opened, although the lines main.MyFrame INFO MyFrame.__init__() called. main.MyApp INFO MyApp.OnInit() called. shouldget displayed within a frame and not on the console. It seems to me that wx.App can't redirect stderr to a frame as soon as a logger instance uses stderr as output. wxPythons Docs claim the wanted behavior though, see here. Any ideas? Uwe

  • How to decrypt a string in C# that was encrypted in Delphi

    - by Simon Linder
    Hi all, we have a project written in Delphi that we want to convert to C#. Problem is that we have some passwords and settings that are encrypted and written into the registry. When we need a specified password we get it from the registry and decrypt it so we can use it. For the conversion into C# we have to do it the same way so that the application can also be used by users that have the old version and want to upgrade it. Here is the code we use to encrypt/decrypt strings in Delphi: unit uCrypt; interface function EncryptString(strPlaintext, strPassword : String) : String; function DecryptString(strEncryptedText, strPassword : String) : String; implementation uses DCPcrypt2, DCPblockciphers, DCPdes, DCPmd5; const CRYPT_KEY = '1q2w3e4r5t6z7u8'; function EncryptString(strPlaintext) : String; var cipher : TDCP_3des; strEncryptedText : String; begin if strPlaintext <> '' then begin try cipher := TDCP_3des.Create(nil); try cipher.InitStr(CRYPT_KEY, TDCP_md5); strEncryptedText := cipher.EncryptString(strPlaintext); finally cipher.Free; end; except strEncryptedText := ''; end; end; Result := strEncryptedText; end; function DecryptString(strEncryptedText) : String; var cipher : TDCP_3des; strDecryptedText : String; begin if strEncryptedText <> '' then begin try cipher := TDCP_3des.Create(nil); try cipher.InitStr(CRYPT_KEY, TDCP_md5); strDecryptedText := cipher.DecryptString(strEncryptedText); finally cipher.Free; end; except strDecryptedText := ''; end; end; Result := strDecryptedText; end; end. So for example when we want to encrypt the string asdf1234 we get the result WcOb/iKo4g8=. We now want to decrypt that string in C#. Here is what we tried to do: public static void Main(string[] args) { string Encrypted = "WcOb/iKo4g8="; string Password = "1q2w3e4r5t6z7u8"; string DecryptedString = DecryptString(Encrypted, Password); } public static string DecryptString(string Message, string Passphrase) { byte[] Results; System.Text.UTF8Encoding UTF8 = new System.Text.UTF8Encoding(); // Step 1. We hash the passphrase using MD5 // We use the MD5 hash generator as the result is a 128 bit byte array // which is a valid length for the TripleDES encoder we use below MD5CryptoServiceProvider HashProvider = new MD5CryptoServiceProvider(); byte[] TDESKey = HashProvider.ComputeHash(UTF8.GetBytes(Passphrase)); // Step 2. Create a new TripleDESCryptoServiceProvider object TripleDESCryptoServiceProvider TDESAlgorithm = new TripleDESCryptoServiceProvider(); // Step 3. Setup the decoder TDESAlgorithm.Key = TDESKey; TDESAlgorithm.Mode = CipherMode.ECB; TDESAlgorithm.Padding = PaddingMode.None; // Step 4. Convert the input string to a byte[] byte[] DataToDecrypt = Convert.FromBase64String(Message); // Step 5. Attempt to decrypt the string try { ICryptoTransform Decryptor = TDESAlgorithm.CreateDecryptor(); Results = Decryptor.TransformFinalBlock(DataToDecrypt, 0, DataToDecrypt.Length); } finally { // Clear the TripleDes and Hashprovider services of any sensitive information TDESAlgorithm.Clear(); HashProvider.Clear(); } // Step 6. Return the decrypted string in UTF8 format return UTF8.GetString(Results); } Well the result differs from the expected result. After we call DecryptString() we expect to get asdf1234but we get something else. Does anyone have an idea of how to decrypt that correctly? Thanks in advance Simon

  • Android AsyncTask testing problem with Android Test Framework

    - by Vlad
    I have a very simple AsyncTask implementation example and have problem to test it using Android JUnit framework. It works just fine when I instantiate and execute it in normal application. However when it's executed from any of Android Testing framework classes (i.e. AndroidTestCase, ActivityUnitTestCase, ActivityInstrumentationTestCase2 etc) it behaves sarngely: - It executes doInBackground() method correctly - However it doesn't invokes any of its notification methods (onPostExecute(), onProgressUpdate(), etc) -- just silently ignores them whitout showing any errors. This is very simple AsyncTask example package kroz.andcookbook.threads.asynctask; import android.os.AsyncTask; import android.util.Log; import android.widget.ProgressBar; import android.widget.Toast; public class AsyncTaskDemo extends AsyncTask<Integer, Integer, String> { AsyncTaskDemoActivity _parentActivity; int _counter; int _maxCount; public AsyncTaskDemo(AsyncTaskDemoActivity asyncTaskDemoActivity) { _parentActivity = asyncTaskDemoActivity; } @Override protected void onPreExecute() { super.onPreExecute(); _parentActivity._progressBar.setVisibility(ProgressBar.VISIBLE); _parentActivity._progressBar.invalidate(); } @Override protected String doInBackground(Integer... params) { _maxCount = params[0]; for (_counter = 0; _counter <= _maxCount; _counter++) { try { Thread.sleep(1000); publishProgress(_counter); } catch (InterruptedException e) { // Ignore } } } @Override protected void onProgressUpdate(Integer... values) { super.onProgressUpdate(values); int progress = values[0]; String progressStr = "Counting " + progress + " out of " + _maxCount; _parentActivity._textView.setText(progressStr); _parentActivity._textView.invalidate(); } @Override protected void onPostExecute(String result) { super.onPostExecute(result); _parentActivity._progressBar.setVisibility(ProgressBar.INVISIBLE); _parentActivity._progressBar.invalidate(); } @Override protected void onCancelled() { super.onCancelled(); _parentActivity._textView.setText("Request to cancel AsyncTask"); } } This is a test case. Here AsyncTaskDemoActivity is a very simple Activity providing UI for testing AsyncTask in mode: package kroz.andcookbook.test.threads.asynctask; import java.util.concurrent.ExecutionException; import kroz.andcookbook.R; import kroz.andcookbook.threads.asynctask.AsyncTaskDemo; import kroz.andcookbook.threads.asynctask.AsyncTaskDemoActivity; import android.content.Intent; import android.test.ActivityUnitTestCase; import android.widget.Button; public class AsyncTaskDemoTest2 extends ActivityUnitTestCase<AsyncTaskDemoActivity> { AsyncTaskDemo _atask; private Intent _startIntent; public AsyncTaskDemoTest2() { super(AsyncTaskDemoActivity.class); } protected void setUp() throws Exception { super.setUp(); _startIntent = new Intent(Intent.ACTION_MAIN); } protected void tearDown() throws Exception { super.tearDown(); } public final void testExecute() { startActivity(_startIntent, null, null); Button btnStart = (Button) getActivity().findViewById(R.id.Button01); btnStart.performClick(); assertNotNull(getActivity()); } } All this code is working just fine, except the fact that AsynTask doesn't invoke it's notification methods when executed by whithin Android Testing Framework. Any ideas?

  • Best practices for using the Entity Framework with WPF DataBinding

    - by Ken Smith
    I'm in the process of building my first real WPF application (i.e., the first intended to be used by someone besides me), and I'm still wrapping my head around the best way to do things in WPF. It's a fairly simple data access application using the still-fairly-new Entity Framework, but I haven't been able to find a lot of guidance online for the best way to use these two technologies (WPF and EF) together. So I thought I'd toss out how I'm approaching it, and see if anyone has any better suggestions. I'm using the Entity Framework with SQL Server 2008. The EF strikes me as both much more complicated than it needs to be, and not yet mature, but Linq-to-SQL is apparently dead, so I might as well use the technology that MS seems to be focusing on. This is a simple application, so I haven't (yet) seen fit to build a separate data layer around it. When I want to get at data, I use fairly simple Linq-to-Entity queries, usually straight from my code-behind, e.g.: var families = from family in entities.Family.Include("Person") orderby family.PrimaryLastName, family.Tag select family; Linq-to-Entity queries return an IOrderedQueryable result, which doesn't automatically reflect changes in the underlying data, e.g., if I add a new record via code to the entity data model, the existence of this new record is not automatically reflected in the various controls referencing the Linq query. Consequently, I'm throwing the results of these queries into an ObservableCollection, to capture underlying data changes: familyOC = new ObservableCollection<Family>(families.ToList()); I then map the ObservableCollection to a CollectionViewSource, so that I can get filtering, sorting, etc., without having to return to the database. familyCVS.Source = familyOC; familyCVS.View.Filter = new Predicate<object>(ApplyFamilyFilter); familyCVS.View.SortDescriptions.Add(new System.ComponentModel.SortDescription("PrimaryLastName", System.ComponentModel.ListSortDirection.Ascending)); familyCVS.View.SortDescriptions.Add(new System.ComponentModel.SortDescription("Tag", System.ComponentModel.ListSortDirection.Ascending)); I then bind the various controls and what-not to that CollectionViewSource: <ListBox DockPanel.Dock="Bottom" Margin="5,5,5,5" Name="familyList" ItemsSource="{Binding Source={StaticResource familyCVS}, Path=., Mode=TwoWay}" IsSynchronizedWithCurrentItem="True" ItemTemplate="{StaticResource familyTemplate}" SelectionChanged="familyList_SelectionChanged" /> When I need to add or delete records/objects, I manually do so from both the entity data model, and the ObservableCollection: private void DeletePerson(Person person) { entities.DeleteObject(person); entities.SaveChanges(); personOC.Remove(person); } I'm generally using StackPanel and DockPanel controls to position elements. Sometimes I'll use a Grid, but it seems hard to maintain: if you want to add a new row to the top of your grid, you have to touch every control directly hosted by the grid to tell it to use a new line. Uggh. (Microsoft has never really seemed to get the DRY concept.) I almost never use the VS WPF designer to add, modify or position controls. The WPF designer that comes with VS is sort of vaguely helpful to see what your form is going to look like, but even then, well, not really, especially if you're using data templates that aren't binding to data that's available at design time. If I need to edit my XAML, I take it like a man and do it manually. Most of my real code is in C# rather than XAML. As I've mentioned elsewhere, entirely aside from the fact that I'm not yet used to "thinking" in it, XAML strikes me as a clunky, ugly language, that also happens to come with poor designer and intellisense support, and that can't be debugged. Uggh. Consequently, whenever I can see clearly how to do something in C# code-behind that I can't easily see how to do in XAML, I do it in C#, with no apologies. There's been plenty written about how it's a good practice to almost never use code-behind in WPF page (say, for event-handling), but so far at least, that makes no sense to me whatsoever. Why should I do something in an ugly, clunky language with god-awful syntax, an astonishingly bad editor, and virtually no type safety, when I can use a nice, clean language like C# that has a world-class editor, near-perfect intellisense, and unparalleled type safety? So that's where I'm at. Any suggestions? Am I missing any big parts of this? Anything that I should really think about doing differently?

  • Encoded nsstring becomes invalid, "normal" nsstring remains

    - by shoreline
    I'm running into a problem with a string that contains encoded characters. Specifically, if the string has encoded characters it eventually becomes invalid while a "normal" string will not. in the .h file: @interface DirViewController : TTThumbsViewController <UIActionSheetDelegate,UINavigationControllerDelegate,UIImagePickerControllerDelegate> { NSString *sourceFolder; NSString *encodedSourceFolder; } @property (nonatomic, retain) NSString *sourceFolder; @property (nonatomic, retain) NSString *encodedSourceFolder; in the .m file: - (id)initWithFolder:(NSString*)folder query:(NSDictionary*)query { if (self = [super init]) { sourceFolder = folder; } return self; } Up to now everything seems to run as expected. In viewDidLoad I have the following: sourceFolderCopy = [self urlEncodeValue:(sourceFolder)]; //I also have this button, which I'll refer to later: UIBarButtonItem *importButton = [[UIBarButtonItem alloc] initWithTitle:@"Import/Export" style:UIBarButtonItemStyleBordered target:self action:@selector(importFiles:)]; self.navigationItem.rightBarButtonItem = importButton; Which uses the following method to encode the string (if it has characters I want encoded): - (NSString *)urlEncodeValue:(NSString *)str { NSString *result = (NSString *) CFURLCreateStringByAddingPercentEscapes (kCFAllocatorDefault, (CFStringRef)str, NULL, CFSTR(":/?#[]@!$&’()*+,;="), kCFStringEncodingUTF8); return [result autorelease]; } If I NSLog result, I get the expected values. If the string has characters like a white space, I get a string with encoding. If the string doesn't have any characters that need to be encoded, it just gives me the original string. I have a button on the nav bar which begins an image import process by opening an action sheet. Once the method for the action sheet starts, my string is invalid - but only if it contains encoded characters. If it is just a "normal" string, everything is fine and acts as expected. Am I off on my encoding? At first I thought it might be a memory problem but I can't figure out why that would affect only encoded strings. Here's where the action sheet is defined (and the first place I can see the encoded string becoming invalid) the NSLog statements are where it crashes: - (IBAction)importFiles:(id)sender { NSLog(@"logging encodedSF from import files:"); NSLog(@"%@",encodedSourceFolder);//crashes right here NSLog(@"%@",sourceFolder); if (shouldNavigate == NO) { NSString *msg = nil; msg = @"It is not possible to import or export images while in image selection mode."; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Unable to Import/Export" message:msg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; [msg release]; } else{ UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"What would you like to do?" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Import Photos (Picker)", @"Export Photos", nil, nil]; [actionSheet showInView:self.view]; [actionSheet release]; } } I don't get any crash errors going to the console. By using breakpoints I was able to see that the encodedSourceFolder is invalid in the action sheet method.

  • Deploying WCF Tutorial App on IIS7: "The type could not be found"

    - by Jimmy
    Hello, I've been trying to follow this tutorial for deploying a WCF sample to IIS . I can't get it to work. This is a hosted site, but I do have IIS Manager access to the server. However, in step 2 of the tutorial, I can't "create a new IIS application that is physically located in this application directory". I can't seem to find a menu item, context menu item, or what not to create a new application. I've been right-clicking everywhere like crazy and still can't figure out how to create a new app. I suppose that's probably the root issue, but I tried a few other things (described below) just in case that actually is not the issue. Here is a picture of what I see in IIS Manager, in case my words don't do it justice: This is "deployed" at http://test.com.cws1.my-hosting-panel.com/IISHostedCalcService/Service.svc . The error says: The type 'Microsoft.ServiceModel.Samples.CalculatorService', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found. I also tried to create a virtual dir (IISHostedCalc) in dotnetpanel that points to IISHostedCalcService . When I navigate to http://test.com.cws1.my-hosting-panel.com/IISHostedCalc/Service.svc , then there is a different error: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. Interestingly enough, if I click on View Applications, it seems like the virtual directory is an application (see image below)... although, as per the error message above, it doesn't work. As per the tutorial, there was no compiling involved; I just dropped the files on the server as follow inside the folder IISHostedCalcService: service.svc Web.config <dir: App_Code> Service.cs service.svc contains: <%@ServiceHost language=c# Debug="true" Service="Microsoft.ServiceModel.Samples.CalculatorService"%> (I tried with quotes around the c# attribute, as this looks a little strange without quotes, but it made no difference) Web.config contains: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <services> <service name="Microsoft.ServiceModel.Samples.CalculatorService"> <!-- This endpoint is exposed at the base address provided by host: http://localhost/servicemodelsamples/service.svc --> <endpoint address="" binding="wsHttpBinding" contract="Microsoft.ServiceModel.Samples.ICalculator" /> <!-- The mex endpoint is explosed at http://localhost/servicemodelsamples/service.svc/mex --> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> </system.serviceModel> <system.web> <customErrors mode="Off"/> </system.web> </configuration> Service.cs contains: using System; using System.ServiceModel; namespace Microsoft.ServiceModel.Samples { [ServiceContract] public interface ICalculator { [OperationContract] double Add(double n1, double n2); [OperationContract] double Subtract(double n1, double n2); [OperationContract] double Multiply(double n1, double n2); [OperationContract] double Divide(double n1, double n2); } public class CalculatorService : ICalculator { public double Add(double n1, double n2) { return n1 + n2; } public double Subtract(double n1, double n2) { return n1 - n2; } public double Multiply(double n1, double n2) { return n1 * n2; } public double Divide(double n1, double n2) { return n1 / n2; } } }

  • How to fix an endpoint/configuration error using WCF in VB.NET

    - by Eric
    I'm working with a small web page that is meant to assist the users of my application. This web page takes a file and sends it to a central server, which then does something with the data and returns a result. I created this application some time ago and am coming back to it recently. I am getting some kind of configuration error right now, although this application used to work. When it stopped working, whenever I ran the page and sent the data to the central server, I would get this error: "Could not find default endpoint element that references contract 'CentralService.ICwCentralService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element." Looking at some other issues on the net, I thought I might have had the answer. The service reference to the endpoint was contained in a separate project from the code that called it, but the configuration file in that project had no information about the endpoint. So, I added these entries to the web.config file in the main project: <system.serviceModel> <bindings> <wsHttpBinding> <binding name="wsHttpEndpoint" closeTimeout="00:01:00" openTimeout="00:0:10" receiveTimeout="01:10:00" sendTimeout="01:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="999999999" maxReceivedMessageSize="999999999" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="999999999" maxStringContentLength="999999999" maxArrayLength="999999999" maxBytesPerRead="999999999" maxNameTableCharCount="999999999" /> <reliableSession ordered="true" inactivityTimeout="01:10:00" enabled="false" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://localhost:22269/CwCentralService.svc" binding="wsHttpBinding" bindingConfiguration="wsHttpEndpoint" contract="CentralService.ICwCentralService" name="wsHttpEndpoint"> <identity> <servicePrincipalName /> </identity> </endpoint> </client> </system.serviceModel> Now, if I run it, I'm still getting an error: "The remote server returned an unexpected response: (400) Bad Request." The strange thing is, though, I took those entries from another project that contacts the central server. That application has no problems contacting the central server using these settings. It's not a web page application, but I don't see how that would require these settings to change. I cannot tell what started causing these errors or when. I assume its something that changed outside of the application (e.g. the libraries referenced) that requires an update to the configuration in the application. I am currently using .NET 3.0 for all of my applications. Any help would be appreciated.

  • VS2010 Assembly Load Error

    - by Nate
    I am getting the following error when I try to build an ASP.NET 4 project in Visual Studio 2010: "Could not load file or assembly 'file:///C:\Dev\project\trunk\bin\Elmah.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)". I have verified that the dll does, in fact, exist, and is getting copied to the bin folder correctly. I have also tried removing and then re-adding the reference to the project. The build only fails when I switch the Solution Configuration to "Release". It does not fail when the Solution Configuration is set to "Debug". The only difference between the two configurations (that I know of) is shown in the following Web.config transform, Web.Release.config: <?xml version="1.0"?> <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"> <connectionStrings> <add name="SqlServer" connectionString="" providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/> </connectionStrings> <system.web> <compilation xdt:Transform="RemoveAttributes(debug)" /> <customErrors mode="On" xdt:Transform="Replace"> <error statusCode="404" redirect="lost.htm" /> <error statusCode="500" redirect="uhoh.htm" /> </customErrors> </system.web> </configuration> I have tried using Fusion Log Viewer to track down the assembly binding issue, but it looks like it is finding and loading the assembly correctly.

  • MXMLC Ant task results in java.lang.OutOFMemoryError

    - by Mims H. Wright
    I'm making a change to a set of code for a Flex project that I didn't write and was set up to compile using ant tasks. I assume that the codebase was stable at the last checkin but I'm running into memory issues when trying to build a project using MXMLC and ant (see stack trace below). Before, I was just getting an out of memory error. I tried using a different machine and got this more verbose exception (including problems with the image fetcher). I've tried using various versions of the SDK, I've tried replacing the <mxmlc> tag with <exec executable="mxmlc"> with no luck.

  • How can I generate a client proxy for a WCF service with an HTTPS endpoint?

    - by ng5000
    Might be the same issue as this previuos question: WCF Proxy but not sure... I have an HTTPS service connfigured to use transport security and, I hope, Windows credentials. The service is only accessed internally (i.e. within the intranet). The configuration is as follows: <configuration> <system.serviceModel> <services> <service name="WCFTest.CalculatorService" behaviorConfiguration="WCFTest.CalculatorBehavior"> <host> <baseAddresses> <add baseAddress = "https://localhost:8000/WCFTest/CalculatorService/" /> </baseAddresses> </host> <endpoint address ="basicHttpEP" binding="basicHttpBinding" contract="WCFTest.ICalculatorService" bindingConfiguration="basicHttpBindingConfig"/> <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"/> </service> </services> <bindings> <basicHttpBinding> <binding name="basicHttpBindingConfig"> <security mode="Transport"> <transport clientCredentialType = "Windows"/> </security> </binding> </basicHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="WCFTest.CalculatorBehavior"> <serviceAuthorization impersonateCallerForAllOperations="false" principalPermissionMode="UseWindowsGroups" /> <serviceCredentials > <windowsAuthentication allowAnonymousLogons="false" includeWindowsGroups="true" /> </serviceCredentials> <serviceMetadata httpsGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="False" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration> When I run the service I can't see the service in IE. I get a "this page can not be displayed" error. If I try and create a client in VS2008 via the "add service reference" wizard I get this error: There was an error downloading 'https://localhost:8000/WCFTest/CalculatorService/'. There was an error downloading 'https://localhost:8000/WCFTest/CalculatorService/'. The underlying connection was closed: An unexpected error occurred on a send. Authentication failed because the remote party has closed the transport stream. Metadata contains a reference that cannot be resolved: 'https://localhost:8000/WCFTest/CalculatorService/'. An error occurred while making the HTTP request to https://localhost:8000/WCFTest/CalculatorService/. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server. The underlying connection was closed: An unexpected error occurred on a send. Authentication failed because the remote party has closed the transport stream. If the service is defined in the current solution, try building the solution and adding the service reference again. I think I'm missing some fundamental basics here. Do I need to set up some certificates? Or should it all just work as it seems to do when I use NetTcpBinding? Thanks

  • WPF, UserControl, and Commands? Oh my!

    - by Greg D
    (This question is related to another one, but different enough that I think it warrants placement here.) Here's a (heavily snipped) Window: <Window x:Class="Gmd.TimeTracker2.TimeTrackerMainForm" xmlns:local="clr-namespace:Gmd.TimeTracker2" xmlns:localcommands="clr-namespace:Gmd.TimeTracker2.Commands" x:Name="This" DataContext="{Binding ElementName=This}"> <Window.CommandBindings> <CommandBinding Command="localcommands:TaskCommands.ViewTaskProperties" Executed="HandleViewTaskProperties" CanExecute="CanViewTaskPropertiesExecute" /> </Window.CommandBindings> <DockPanel> <!-- snip stuff --> <Grid> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <!-- snip more stuff --> <Button Content="_Create a new task" Grid.Row="1" x:Name="btnAddTask" Click="HandleNewTaskClick" /> </Grid> </DockPanel> </Window> and here's a (heavily snipped) UserControl: <UserControl x:Class="Gmd.TimeTracker2.TaskStopwatchControl" xmlns:local="clr-namespace:Gmd.TimeTracker2" xmlns:localcommands="clr-namespace:Gmd.TimeTracker2.Commands" x:Name="This" DataContext="{Binding ElementName=This}"> <UserControl.ContextMenu> <ContextMenu> <MenuItem x:Name="mnuProperties" Header="_Properties" Command="{x:Static localcommands:TaskCommands.ViewTaskProperties}" CommandTarget="What goes here?" /> </ContextMenu> </UserControl.ContextMenu> <StackPanel> <TextBlock MaxWidth="100" Text="{Binding Task.TaskName, Mode=TwoWay}" TextWrapping="WrapWithOverflow" TextAlignment="Center" /> <TextBlock Text="{Binding Path=ElapsedTime}" TextAlignment="Center" /> <Button Content="{Binding Path=IsRunning, Converter={StaticResource boolToString}, ConverterParameter='Stop Start'}" Click="HandleStartStopClicked" /> </StackPanel> </UserControl> Through various techniques, a UserControl can be dynamically added to the Window. Perhaps via the Button in the window. Perhaps, more problematically, from a persistent backing store when the application is started. As can be seen from the xaml, I've decided that it makes sense for me to try to use Commands as a way to handle various operations that the user can perform with Tasks. I'm doing this with the eventual goal of factoring all command logic into a more formally-defined Controller layer, but I'm trying to refactor one step at a time. The problem that I'm encountering is related to the interaction between the command in the UserControl's ContextMenu and the command's CanExecute, defined in the Window. When the application first starts and the saved Tasks are restored into TaskStopwatches on the Window, no actual UI elements are selected. If I then immediately r-click a UserControl in the Window in an attempt to execute the ViewTaskProperties command, the CanExecute handler never runs and the menu item remains disabled. If I then click some UI element (e.g., the button) just to give something focus, the CanExecute handlers are run with the CanExecuteRoutedEventArgs's Source property set to the UI element that has the focus. In some respect, this behavior seems to be known-- I've learned that menus automat

  • How to get maven gwt 2.0 build working

    - by Pieter Breed
    EDIT: Added some of the output of the mvn -X -e commands at the end My company is developing a GWT application. We've been using maven 2 and GWT 1.7 successfully for quite a while. We recently decided to upgrade to GWT 2.0. We've already updated the eclipse project and we are able to successfully run the application in dev-mode. We are struggling to get the application built using maven though. I'm hoping somebody can tell me what I'm doing wrong here since I'm running out of time on this.

  • Windows CE Programming Serial Port - Getting Garbled Output

    - by user576639
    I am programming a Windows CE 6 device (Motorola MC3100 scanner Terminal). Using Lazarus FPC to compile it. After 3 weeks work I reluctantly post here in the hope someone can suggest why I am getting garbled output from the serial port. The code I am using is posted below. This is the standard code I have found from several places. The OpenPort works OK. When I send the string using SendString('ABCDEF') I get garbled input to the PC Serial port such as: 4[#131][#26][#0][#0][#0][#0] (the bracketed data indicates that it is a non-printable character ASCII Code) Obviously it is connecting to the port OK AND it is sending the correct no of characters (7). I have tried all combinations of Baud Rate, Data Bits, Parity and Stop Bits without any joy. Also tried changing cable, on a different PC etc. Could it be I need to set something else in the DCB? Any help or suggestions would be GREATLY appreciated. unit Unit1; {$mode objfpc}{$H+} interface uses Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls, ExtCtrls, Windows, LResources; type { TForm1 } TForm1 = class(TForm) Button1: TButton; Button2: TButton; Label1: TLabel; procedure Button1Click(Sender: TObject); procedure Button2Click(Sender: TObject); function OpenPort(ComPort:String;BaudRate,ByteSize,Parity,StopBits:integer):String; procedure SendString(str:String); private { private declarations } public { public declarations } end; var Form1: TForm1; cc:TCOMMCONFIG; Connected:Boolean; implementation {$R *.lfm} var F: TextFile; var hComm: THandle; str: String; lrc: LongWord; { TForm1 } function OpenPort(ComPort:String;BaudRate,ByteSize,Parity,StopBits:integer):String; var cc:TCOMMCONFIG; SWide:WideString; Port:LPCWSTR; begin SWide:=ComPort; Port:=PWideChar(SWide); result:=''; if (1=1) then begin Connected:=False; hComm:=CreateFile(Port, GENERIC_READ or GENERIC_WRITE,0, nil,OPEN_EXISTING,0,0); if (hComm = INVALID_HANDLE_VALUE) then begin ShowMessage('Fail to Open'); exit; end; GetCommState(hComm,cc.dcb); cc.dcb.BaudRate:=BaudRate; cc.dcb.ByteSize:=ByteSize; cc.dcb.Parity:=Parity; cc.dcb.StopBits:=StopBits; if not SetCommState(hComm, cc.dcb) then begin result:='SetCommState Error!'; CloseHandle(hComm); exit; end; Connected:=True; end; end; procedure TForm1.Button1Click(Sender: TObject); begin OpenPort('COM1:',9600,8,0,0); end; procedure TForm1.Button2Click(Sender: TObject); begin SendString('ABCDEFG'); end; procedure TForm1.SendString(str:String); var lrc:LongWord; begin if (hComm=0) then exit; try if not PurgeComm(hComm, PURGE_TXABORT or PURGE_TXCLEAR) then raise Exception.Create('Unable to purge com: '); except Exit; end; WriteFile(hComm,str,Length(str), lrc, nil); end; end.

  • how get validation messages from mangomapper using rails console ?

    - by Alex
    Hi, I am basically teaching myself how to use RoR and MongoDB at the same time. I am following the very good book / tutorial : http://railstutorial.org/ I decided to replace Sqlite3 by MongoDB using the mongomapper gem. Everything works out about alright, but I am having some non-blocking little issues that I truly wish I could get rid of. In chapter 6, when working with validation I got 2 issues: - I don't know how to get the validations messages back like with Sqlite3. The "standard" code is: $ rails console --sandbox >> user = User.new(:name => "", :email => "[email protected]") >> user.save => false >> user.valid? => false >> user.errors.full_messages => ["Name can't be blank"] but if I try to do the same with MongoMapper, it throws an error saying that errors is undefined function. So does it mean that this is simply not implemented in mongomapper / mongo driver ? Or is there some other clever way to do this that I could not figure ? Additional, 2 things here: - I following the exemple in the book to the line, so I was expecting to be able to use the console in sandbox mode, but apparently that does not work either: (...)ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/console/sandbox.rb:1:in `<top (required)>': uninitialized constant ActiveRecord (NameError) from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/application.rb:226:in `initialize_console' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/application.rb:153:in `load_console' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands/console.rb:26:in `start' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands/console.rb:8:in `start' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands.rb:23:in `<top (required)>' from script/rails:6:in `require' from script/rails:6:in `<main>' Also, in the book they call "user" but I need to call "User" (note the capital U) why is that ? Is it like mangomapper does not follow the Ruby naming convention or something ? And finally, I am trying to validate the field email with a regex as shown in the tutorial. It does not throws any errors at the code, but whenever I try to insert it just won't ever accept it unless I comment out the :format option... class User include MongoMapper::Document key :name, String, :required => true, :length => { :maximum => 50 } key :email, String, :required => true, # :format => { :with => email_regex }, :uniqueness => { :case_sentitive => false} timestamps! end Any advices you can provide on those topics would help me a lot ! Thanks, Alex

  • iPhone SDK 3.0 and symbolicatecrash not getting along?

    - by Steve
    * UPDATE * I've reinstalled with Snow Leopard, clean install. Completely wiped my existing Leopard install. Same problem persists. I've tried numbers of versions of symbolicatecrash to resolve symbols in my crash reports. From the version provided by Apple, to Alan's Quatermain's version posted on GitHub and finally from http://openradar.appspot.com/6438643. For whatever reason, the best results I can get is for symbols on my own libraries to get resolved. Normally, this is enough data to point me in the right direction -- other times it is not. With 2.x I had no problems getting the symbols for my code + Apple provided libraries from within the stack traces in each thread. Most likely an issue with my environment here, I'm not at all doubting the work that Apple or Alan have done. Yes I'm certain the dSYM I have stashed away is the same exact one that's generating the crash report. Although 'Foo' is me, and getting symbols from it is wonderful, I need to see symbols from the other functions in the stack to truly understand my reports. Note: For devices that crash running the app on iPhone OS 2.2.1, I have no problem getting all symbols. This is an iPhone OS 3.0 issue it appears. Also, while running symbolicatecrash in verbose mode here's a few of the things that struck me as wrong: - NO MATCH NOT searching in Spotlight for dsym with UUID of /System/Library/Frameworks/CoreFoundation.framework/CoreFoundation ## Warning: Can't find any unstripped binary that matches version of /System/Library/Frameworks/CoreFoundation.framework/CoreFoundation ..........fetching symbol file for libobjc.A.dylib--[undef] Searching [/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A345)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A347)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.1 (5B108)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.2 (5C1)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1.1/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2.1/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0 (7A341)/Symbols/usr/lib/libobjc.A.dylib]...--[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A345)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A347)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.1 (5B108)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.2 (5C1)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1.1/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2.1/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0 (7A341)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH NOT searching in Spotlight for dsym with UUID of /usr/lib/libobjc.A.dylib ## Warning: Can't find any unstripped binary that matches version of /usr/lib/libobjc.A.dylib Here's an example of the crash report after running it through symbolicatecrash: Thread 0 Crashed: 0 libSystem.B.dylib 0x31dc476c 0x31d46000 + 517996 1 libSystem.B.dylib 0x31dc4755 0x31d46000 + 517973 2 Foo 0x00053075 uncaught_exception_handler + 21 3 CoreFoundation 0x3028f65f 0x301fd000 + 599647 4 libobjc.A.dylib 0x30013693 0x3000c000 + 30355 5 libstdc++.6.dylib 0x374ccc2d 0x3748a000 + 273453 6 libstdc++.6.dylib 0x374ccc81 0x3748a000 + 273537 7 libstdc++.6.dylib 0x374ccd4d 0x3748a000 + 273741 8 libobjc.A.dylib 0x300135ff 0x3000c000 + 30207 9 CoreFoundation 0x30222f2d 0x301fd000 + 155437 10 CoreFoundation 0x30222ecb 0x301fd000 + 155339 11 Foundation 0x30521e33 0x30501000 + 134707 12 Foundation 0x30570d47 0x30501000 + 458055 13 Foo 0x0000a1db -[Bar barfoo] (Bar.m:1617) 14 Foo 0x00032f73 -[MyViewController foobar] (MyViewController.m:727) 15 Foo 0x000329b9 -[MyViewController foobar] (MyViewController.m:666) 16 Foo 0x00031fab -[MyViewController tabBar:tabSelected:] (MyViewController.m:440) 17 Foo 0x00068d41 -[TTTabBar setSelectedTabIndex:] (TTTabBar.m:160) 18 Foo 0x00068ca3 -[TTTabBar setSelectedTabView:] (TTTabBar.m:142) 19 Foo 0x000689cf -[TTTabBar tabTouchedUp:] (TTTabBar.m:83) 20 CoreFoundation 0x302552f9 0x301fd000 + 361209 21 UIKit 0x3094d101 0x308ed000 + 393473 22 UIKit 0x3094d0a1 0x308ed000 + 393377 23 UIKit 0x3094d073 0x308ed000 + 393331 24 UIKit 0x3094cdcd 0x308ed000 + 392653 25 UIKit 0x309779c1 0x308ed000 + 567745 26 UIKit 0x30977011 0x308ed000 + 565265 27 UIKit 0x309767d9 0x308ed000 + 563161 28 UIKit 0x30923613 0x308ed000 + 222739 29 UIKit 0x30923163 0x308ed000 + 221539 30 GraphicsServices 0x32045a4d 0x32041000 + 19021 31 CoreFoundation 0x30253041 0x301fd000 + 352321 32 CoreFoundation 0x30252771 0x301fd000 + 350065 33 GraphicsServices 0x32044b0f 0x32041000 + 15119 34 GraphicsServices 0x32044bbb 0x32041000 + 15291 35 UIKit 0x308f0363 0x308ed000 + 13155 36 UIKit 0x308ef121 0x308ed000 + 8481 37 Foo 0x00002097 main (main.m:13)

  • Ninject 2 and MVC 2.0

    - by theouteredge
    I've updated a project to VS2010 and MVC2 from VS2008 and MVC1. I'm having problems with Ninject not finding controllers within Areas Here is my global.asax.cs file: namespace Website { // Note: For instructions on enabling IIS6 or IIS7 classic mode, // visit http://go.microsoft.com/?LinkId=9394801 public class MvcApplication : NinjectHttpApplication { public static StandardKernel NinjectKernel; public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Balance", "Balance/{action}/{month}/{year}", new { controller = "Balance", action = "Index", month = DateTime.Now.Month, year = DateTime.Now.Year } ); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Login", action = "Index", id = "" } // Parameter defaults ); } /* protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); // initializes the NHProfiler so you can see what is going on with your queries HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize(); } */ protected override void OnApplicationStarted() { RegisterRoutes(RouteTable.Routes); AreaRegistration.RegisterAllAreas(); RegisterAllControllersIn(Assembly.GetExecutingAssembly()); } protected void Application_Error(object sender, EventArgs e) { var errorService = NinjectKernel.Get<IErrorLogService>(); errorService.LogError(HttpContext.Current.Server.GetLastError().GetBaseException(), "AppSite"); } protected override IKernel CreateKernel() { if (NinjectKernel == null) { NinjectKernel = new StandardKernel(new ServiceModule()); } return NinjectKernel; } } public class ServiceModule : NinjectModule { public override void Load() { Bind<IHelper>().To<Helper>().InRequestScope(); Bind<IErrorLogService>().To<ErrorLogService>(); Bind<INHSessionFactory>().To<NHSessionFactory>().InSingletonScope(); Bind<ISessionFactory>().ToMethod(ctx => ctx.Kernel.Get<INHSessionFactory>().GetSessionFactory()) .InSingletonScope(); Bind<INHSession>().To<NHSession>(); Bind<ISession>().ToMethod(ctx => ctx.Kernel.Get<INHSession>().GetSession()); } } } Accessing controllers within the /Controllers folder works OK, but accessing controllers within a /Areas/Member/Controller throws the following error: Server Error in '/' Application. Cannot be null Parameter name: service Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentNullException: Cannot be null Parameter name: service Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace: [ArgumentNullException: Cannot be null Parameter name: service] Ninject.ResolutionExtensions.GetResolutionIterator(IResolutionRoot root, Type service, Func`2 constraint, IEnumerable`1 parameters, Boolean isOptional, Boolean isUnique) +193 Ninject.Web.Mvc.NinjectControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType) +41 System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName) +66 System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext, IController& controller, IControllerFactory& factory) +124 System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContextBase httpContext, AsyncCallback callback, Object state) +50 System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContext httpContext, AsyncCallback callback, Object state) +48 System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, Object extraData) +16 System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +8771488 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +184 Version Information: Microsoft .NET Framework Version:4.0.30128; ASP.NET Version:4.0.30128.1 The Url for this request is /Member/Controller/, If I change the Url too /Controller the controller fires but I get an error that the system cannot find the View in the path /Views When it should be looking in /Area/Members/Views I have either done something wrong in the upgrade or I'm missing something bt I just can't figure out what. I've been trying to figure this out for 3 days...
