• ReSharper 8.0 EAP now available

  - by TATWORTH

  Originally posted on: http://geekswithblogs.net/TATWORTH/archive/2013/06/28/resharper-8.0-eap-now-available.aspxJetbrains have just released |ReSharper 8.0 Beta on their Early Access |Programme at http://www.jetbrains.com/resharper/whatsnew/?utm_source=resharper8b&utm_medium=newsletter&utm_campaign=resharper&utm_content=customersResharper 8.0 comes with the following new features:Support for Visual Studio 2013 Preview. Yes, ReSharper is known to work well with the fresh preview of Visual Studio 2013, and if you have already started digging into it, ReSharper 8.0 Beta is ready for the challenge.Faster code fixes. Thanks to the new Fix in Scope feature, you can choose to batch-fix some of the code issues that ReSharper detects in the scope of a project or the whole solution. Supported fixes include removing unused directives and redundant casts.Project dependency viewer. ReSharper is now able to visualize a project dependency graph for a bird's eye view of dependencies within your solution, all without compiling anything!Multifile templates. ReSharper's file templates can now be expanded to generate more than one file. For instance, this is handy for generating pairs of a main logic class and a class for extensions, or sets of partial files.Navigation improvements. These include a new action called Go to Everything to let you search for a file, type or method name from the same input box; support for line numbers in navigation actions; a new tool window called Assembly Explorer for browsing through assemblies; and two more contextual navigation actions: Navigate to Generic Substitutions and Navigate to Assembly Explorer.New solution-wide refactorings. The set of fresh refactorings is headlined by the highly requested Move Instance Method to move methods between classes without making them static. In addition, there are Inline Parameter and Pull Parameter. Last but not least, we're also introducing 4 new XAML-specific refactorings!Extraordinary XAML support. A plethora of new and improved functionality for all developers working with XAML code includes dedicated grid inspections and quick-fixes; Extract Style, Extract, Move and Inline Resource refactorings; atomic renaming of dependency properties; and a lot more.More accessible code completion. ReSharper 8 makes more of its IntelliSense magic available in automatic completion lists, including extension methods and an option to import a type. We're also introducing double completion which gives you additional completion items when you press the corresponding shortcut for the second time.A new level of extensibility. With the new NuGet-based Extension Manager, discovering, installing and uninstalling ReSharper extensions becomes extremely easy in Visual Studio 2010 and higher. When we say extensions, we mean not only full-fledged plug-ins but also sets of templates or SSR patterns that can now be shared much more easily.CSS support improvements. Smarter usage search for CSS attributes, new CSS-specific code inspections, configurable support for CSS3 and earlier versions, compatibility checks against popular browsers - there's a rough outline of what's new for CSS in ReSharper 8.A command-line version of ReSharper. ReSharper 8 goes beyond Visual Studio: we now provide a free standalone tool with hundreds of ReSharper inspections and additionally a duplicate code finder that you can integrate with your CI server or version control system.Multiple minor improvements in areas such as decompiling and code formatting, as well as support for the Blue Theme introduced in Visual Studio 2012 Update 2.

• GameStateManagement and inputs not being recognized

  - by Dave Voyles

  EDIT: I've removed a bit of code from the input class to make this more readable, and updated my StartScreen class, which is now at the bottom. I have the same issues though, but they are explained in my comments on the bottom of this page. It won't let me paste my additional code here (the format comes out crazy), so I've linked to pastebin with the code pastebin I've been trying to implement the MS provided GameStateManagement sample with my game, but it has proven a bit difficult. Really, I'm using Oneksoft's Starter Kit, which uses the MS provided sample, so they are identical, except for my splash screen. I'm able to get the splash screen to launch, where it informs the player to press A to advance the screen, but this doesn't seem to accept any of my inputs. I’ve also added Console.Writeline(“Pressing A”) under the IsMenuPressed method in Input.cs to verify that it is getting called, but for some reason it is constantly spamming my log, rather than just appearing each time I press it. Not sure why this is happening. I have a bit too much code to post it all here, so I’ve attached a link to my .rar with my classes, but I’ll also leave a bit here which I thinkmay be applicable. https://www.dropbox.com/sh/6ek4uru2jc2ch0k/JTeBWN_3PQ What do you guys think the issue is? namespace Pong { public class Input { public const int MaxInputs = 4; public readonly KeyboardState[] CurrentKeyboardState; public readonly GamePadState[] CurrentGamePadState; public KeyboardState[] LastKeyboardState; public GamePadState[] LastGamePadState; public readonly bool[] GamePadWasConnected; public Input() { // Get input state CurrentKeyboardState = new KeyboardState[MaxInputs]; CurrentGamePadState = new GamePadState[MaxInputs]; // Preserving last states to check for isKeyUp events LastKeyboardState = CurrentKeyboardState; LastGamePadState = CurrentGamePadState; } /// <summary> /// Checks for a "menu select" input action. /// The controllingPlayer parameter specifies which player to read input for. /// If this is null, it will accept input from any player.

• Axis2 embedded in my web app is not working

  OKay I lost alsmost the whole day on this. I have a webapp where I would like to add AXIS2 and start working. I added AxisServlets in the web.xml file like - <servlet> <servlet-name>AxisServlet</servlet-name> <display-name>Apache-Axis Servlet</display-name> <servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>AxisServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> I also added Services.xml file like <service name="ReportViewerService"> <description> This is a sample Web Service for illustrating Attachments API of Axis2 </description> <parameter name="ServiceClass">myclass</parameter> <operation name="getReport"> <actionMapping>urn:getReport</actionMapping> <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/> </operation> </service> The directory structure is as mentioned here WEB-ING | - conf | |- axis2.xml |-lib | |- all libs |-services |-ReportViewerService | - META-INF |-services.xml |- web.xml The problem is - after all of these, the service endpoint will not come, I can not see the WSDL file http://localhost:8080/BOReportingServer/services/ReportViewerService?wsdl -- this gives an exception like - Throwable occurred: javax.servlet.ServletException: File &quot;/axis2-web/listSingleService.jsp&quot; not found

• How do you pass a date value to BIRT report via querystring

  - by Tommy

  Hi, I have made a static html page (called start.jsp) containing a form where the user select 2 date ranges and this form has date pickers for those text boxes. When the user submits the form, it should take them to the BIRT report that I have designed. It SHOULD pass the 2 parameters that my report needs (start date and end date). Here is the querystring that gets appended to the URL birt-viewer/run__report=Business_Activity_Monitoring.rptdesign &FilterStartDate=2000-01-01&FilterEndDate=2009-01-01 I get an invalid date error: org.eclipse.birt.report.exception.ViewerValidationException: The parameter "FilterStartDate" is invalid. The value "06-08-2010" is invalid with the type "dateTime". How is it that if I remove the querystring completely, then BIRT will prompt me to enter the start date and end date (screenshot attached). I enter the exact same data that the form tries to send and it works!? This proves that my date string is correctly formatted but yet it will not accept them if they are sent to the BIRT report via the querystring? Seems like it has a problem with the fact that its a string in the first place. I have correctly set up these report parameters in my BIRT report. I have also tried changing them by specifying the "Format as" value to be a "custom" YYYY-MM-dd but this didnt work. Is it even possible to send date parameters to a birt report via querystring? Im guessing the solution will involve converting these strings to dates within the birt report's "script" tab. but I dont know how to access querystring variables from here or how to set report parameter variables. Thanks -Tommy

• Telerik RadGridView problem

  - by Polaris

  I am using Telerik RadGridView in my project. I want to show image in column. GridViewImageColumn col1 = new GridViewImageColumn(); col1.Width = 100; col1.DataMemberBinding = new Binding("id"); col1.Header = "PhotoByConverter"; col1.DataMemberBinding.Converter = new ThumbnailConverter(); grid.Columns.Add(col1); GridViewImageColumn col2 = new GridViewImageColumn(); col2.Width = 100; col2.DataMemberBinding = new Binding("firstName"); col2.Header = "Person name"; col2.DataMemberBinding.Converter = new ThumbnailConverter(); grid.Columns.Add(col2); Grid.ItemsSource=DataTable; First column not wokrs but second works fine. I use Converter for image shown below public class ThumbnailConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { IEnumerable<thumbNail> result = from n in thumbnails where n.personID == value.ToString() select n; if (result != null && result.First().thumbnail != null) { return result.First().thumbnail.file; } else { return null; } } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new Exception("The method or operation is not implemented."); } } I found by id thumbnail of person and set it like data for GridViewImageColumn. I checked with Debuger conveter works properly. I can't undesrtand why it doesn't work. Any ideas?

• Why do I get a DependencyProperty.UnsetValue when converting a value in a MultiBinding?

  - by eskerber

  I have an extremely simple IMultiValueConverter that simply OR's two values. In the example below, I want to invert the first value using an equally simple boolean inverter. <MultiBinding Converter="{StaticResource multiBoolToVis}"> <Binding Path="ConditionA" Converter="{StaticResource boolInverter}"/> <Binding Path="ConditionB"/> </MultiBinding> public class BoolInverterConverter : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if (value is bool) { return !((bool)value); } return null; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } #endregion } When I include the boolInverter, the first value in the MultiValueConverter becomes a "DependencyProperty.UnsetValue". There are no problems when I do not use the converter (other than not the logic I am aiming for, of course). Am I missing something? Stepping through the debugger shows that the InverseBoolConverter is properly inverting the value I pass it, but that value is then not being 'sent' to the MultiValueConverter.

• WPF ICommand over a button

  - by toni

  Hi, I have implemented a custom IComand class for one of my buttons. The button is placed in a page 'MyPage.xaml' but its custom ICommand class is placed in another class, not in the MyPage code behind. Then from XAML I want to bind the button with its custom command class and then I do: MyPage.xaml: <Page ...> <Page.CommandBindings> <CommandBinding Command="RemoveAllCommand" CanExecute="CanExecute" Executed="Execute" /> </Page.CommandBindings> <Page.InputBindings> <MouseBinding Command="RemoveAllCommand" MouseAction="LeftClick" /> </Page.InputBindings> <...> <Button x:Name="MyButton" Command="RemoveAllCommand" .../> <...> </Page> and the custom command button class: // Here I derive from MyPage class because I want to access some objects from // Execute method public class RemoveAllCommand : MyPage, ICommand { public void Execute(Object parameter) { <...> } public bool CanExecute(Object parameter) { <...> } public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } } My problem is how to say MyPage.xaml that Execute and CanExecute methods for the button is in another class and not the code behind where is placed the button. How to say these methods are in RemoveAllCommand Class in XAML page. Also I want to fire this command when click mouse event is produced in the button so I do an input binding, is it correct? Thanks

• Dynamics CRM 2011 - WCF error

  - by bigtv

  I am trying to get to grips with MS Dynamics CRM 2011. I have have the beta installed on a VM and things look pretty good - some great new features etc. However I am getting an exception when trying to connect to the new XRMServices (updated 2011 WCF web services) Exception: System.ServiceModel.ServiceActivationException: The service '/organame/XRMServices/2011/Organization.svc' cannot be activated due to an exception during compilation. The exception message is: 'System.ServiceModel.Description.UseRequestHeadersForMetadataAddressBehavior'. This collection only supports one instance of each type. Parameter name: item. ---> System.ArgumentException: The value could not be added to the collection, as the collection already contains an item of the same type: 'System.ServiceModel.Description.UseRequestHeadersForMetadataAddressBehavior'. This collection only supports one instance of each type. Parameter name: item The only reference to this exception I gave found suggests that it is caused by multiple bindings configured in IIS, which in my case I did have, but the problem persists even after removing them. Any suggestions would be appreciated.

• Pass value of a field to Silverlight ConverterParameter

  - by eidylon

  Hi all, I'm writing my very first Silverlight app. I have a datagrid with a column that has two labels, for the labels, i am using an IValueConverter to conditionally format the data. The label's "Content" is set as such: Content="{Binding HomeScore, Converter={StaticResource fmtshs}}" and Content="{Binding AwayScore, Converter={StaticResource fmtshs}}" The Convert method of my IValueConverter is such: Public Function Convert( ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert Dim score As Long = value, other As Long = parameter Return If(score < 0, "", If(score - other > 5, (other + 5).ToString, score.ToString) ) End Function So what i want to do is in the converter for HomeScore, i want to pass AwayScore to the ConverterParameter, and for AwayScore i want to pass the HomeScore to the converter. In the converter for either score i need to be able to know the value of the other score for formatting purposes. But i cannot figure out the syntax for binding the ConverterParameter to another field. I've tried the following: Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter=AwayScore}" Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter={AwayScore}}" Content="{Binding HomeScore, Converter={StaticResource fmtshs}, ConverterParameter={Binding AwayScore}}" But none of those seem to work. How do i pass a field value to the ConverterParameter?

  I cannot seem to get unity working when attempting to pass in an array of strings into a constructor parameter list, while using XML configuration. When I try the following: <typeConfig ...> <constructor ...> <param ... parameterType="System.String[]"> <array> <value.../> <value.../> </array> </param> </constructor> </typeConfig> for a c'tor which looks like this: void Foo(string[] inputParams_){ ... } It always fails in Unity's FindConstructor(...) method stating that it cannot find a c'tor mathcing the parameter type of String.String Does anyone know how to pass an array of stings successfully into this type of c'tor?

• Wpf binding to a function

  - by carlopenid

  I've a created a simple scrollviewer (pnlDayScroller) and want to have a separate horizontal scrollbar (associated scroller) to do the horizontal scrolling. All works with the below code accept I need to bind the visibility of the associated scroller. I can't simply bind this to the visibility property of the horizontal template part of the scroll viewer as I've set this to be always hidden. The only way I can think to do this is to bind the visibility of the associated scroller to a function such that If associatedScroller.scrollableWidth > 0 then associatedScroller.visibility = visibility.visible else associatedScroller.visibility = visibility.collapsed end if Is this possible to do and if so how do I do it? Private Sub pnlDayScroller_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles pnlDayScroller.Loaded Dim binViewport, binMax, binMin, binSChange, binLChange As Binding Dim horizontalScrollBar As Primitives.ScrollBar = CType(pnlDayScroller.Template.FindName("PART_HorizontalScrollBar", pnlDayScroller), Primitives.ScrollBar) binViewport = New Binding("ViewportSize") binViewport.Mode = BindingMode.OneWay binViewport.Source = horizontalScrollBar associatedScroller.SetBinding(Primitives.ScrollBar.ViewportSizeProperty, binViewport) binMax = New Binding("Maximum") binMax.Mode = BindingMode.OneWay binMax.Source = horizontalScrollBar associatedScroller.SetBinding(Primitives.ScrollBar.MaximumProperty, binMax) binMin = New Binding("Minimum") binMin.Mode = BindingMode.OneWay binMin.Source = horizontalScrollBar associatedScroller.SetBinding(Primitives.ScrollBar.MinimumProperty, binMin) binSChange = New Binding("SmallChange") binSChange.Mode = BindingMode.OneWay binSChange.Source = horizontalScrollBar associatedScroller.SetBinding(Primitives.ScrollBar.SmallChangeProperty, binSChange) binLChange = New Binding("LargeChange") binLChange.Mode = BindingMode.OneWay binLChange.Source = horizontalScrollBar associatedScroller.SetBinding(Primitives.ScrollBar.LargeChangeProperty, binLChange) End Sub Private Sub associatedScroller_Scroll(ByVal sender As System.Object, ByVal e As System.Windows.RoutedPropertyChangedEventArgs(Of Double)) Handles associatedScroller.ValueChanged pnlDayScroller.ScrollToHorizontalOffset(e.NewValue) end sub FOLLOW UP (thanks to JustABill) : I've add this code into the pnlDayScroller sub above (I've discovered scrollableWidth is a property of scrollviewer not scrollbar, but the maximum property gives a result I can use instead) binVisibility = New Binding("Maximum") binVisibility.Mode = BindingMode.OneWay binVisibility.Source = horizontalScrollBar binVisibility.Converter = New ScrollableConverter associatedScroller.SetBinding(Primitives.ScrollBar.VisibilityProperty, binVisibility) and I've created this class Public Class ScrollableConverter Implements IValueConverter Public Function Convert(ByVal value As Object, ByVal targetType As Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements IValueConverter.Convert Dim dblMaximum As Double If targetType IsNot GetType(Visibility) Then Throw New InvalidOperationException("The target must be a visibility") Else dblMaximum = CType(value, Double) Debug.WriteLine("Value of double is " & dblMaximum) If dblMaximum > 0 Then Return Visibility.Visible Else Return Visibility.Collapsed End If End If End Function Public Function ConvertBack(ByVal value As Object, ByVal targetType As Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements IValueConverter.ConvertBack Throw New NotSupportedException() End Function End Class And the problem is resolved.

• Using OLEDB parameters in .NET when connecting to an AS400/DB2

  - by Jeff Stock

  I have been pulling my hair out trying to figure out what I can't get parameters to work in my query. I have the code written in VB.NET trying to do a query to an AS/400. I have IBM Access for Windows installed and I am able to get queries to work, just not with parameters. Any time I include a parameter in my query (ex. @MyParm) it doesn't work. It's like it doesn't replace the parameter with the value it should be. Here's my code: I get the following error: SQL0206: Column @MyParm not in specified tables Here's my code: Dim da As New OleDbDataAdapter Dim dt As New DataTable da.SelectCommand = New OleDbCommand da.SelectCommand.Connection = con da.SelectCommand.CommandText = "SELECT * FROM MyTable WHERE Col1 = @MyParm" With da.SelectCommand.Parameters .Add("@MyParm", OleDbType.Integer, 9) .Item("@MyParm").Value = 5 End With ' I get the error here of course da.Fill(dt) I can replace @MyParm with a literal of 5 and it works fine. What am I missing here? I do this with SQL Server all the time, but this is the first time I am attempting it on an AS400.

Here is how i initialize the form: form.setAction("/submit"); form.setMethod(FormPanel.METHOD_POST); So i though i would have to do this on the servlet: fruit = req.getParameter("fruit") But of course this doesn't work, parameter fruit doesn't exist :/ Edit: Ok i get parameter fruit but it's always "on" I also did try to add the radio button in java with: RadioButton rb0 = new RadioButton("fruit", "apple"); RadioButton rb1 = new RadioButton("fruit", "banana"); fruitPanel.add(rb0); fruitPanel.add(rb1); So how should i do?

• SQLiteQueryBuilder.buildQuery not using selectArgs?

  - by user297468

  Alright, I'm trying to query a sqlite database. I was trying to be good and use the query method of SQLiteDatabase and pass in the values in the selectArgs parameter to ensure everything got properly escaped, but it wouldn't work. I never got any rows returned (no errors, either). I started getting curious about the SQL that this generated so I did some more poking around and found SQLiteQueryBuilder (and apparently Stack Overflow doesn't handle links with parentheses in them well, so I can't link to the anchor for the buildQuery method), which I assume uses the same logic to generate the SQL statement. I did this: SQLiteQueryBuilder builder = new SQLiteQueryBuilder(); builder.setTables(BarcodeDb.Barcodes.TABLE_NAME); String sql = builder.buildQuery(new String[] { BarcodeDb.Barcodes.ID, BarcodeDb.Barcodes.TIMESTAMP, BarcodeDb.Barcodes.TYPE, BarcodeDb.Barcodes.VALUE }, "? = '?' AND ? = '?'", new String[] { BarcodeDb.Barcodes.VALUE, barcode.getValue(), BarcodeDb.Barcodes.TYPE, barcode.getType()}, null, null, null, null); Log.d(tag, "Query is: " + sql); The SQL that gets logged at this point is: SELECT _id, timestamp, type, value FROM barcodes WHERE (? = '?' AND ? = '?') However, here's what the documentation for SQLiteQueryBuilder.buildQuery says about the selectAgs parameter: You may include ?s in selection, which will be replaced by the values from selectionArgs, in order that they appear in the selection. ...but it isn't working. Any ideas?

• ReSharper - Possible Null Assignment when using Microsoft.Contracts

  - by HVS

  Is there any way to indicate to ReSharper that a null reference won't occur because of Design-by-Contract Requires checking? For example, the following code will raise the warning (Possible 'null' assignment to entity marked with 'NotNull' attribute) in ReSharper on lines 7 and 8: private Dictionary<string, string> _Lookup = new Dictionary<string, string>(); public void Foo(string s) { Contract.Requires(!String.IsNullOrEmpty(s)); if (_Lookup.ContainsKey(s)) _Lookup.Remove(s); } What is really odd is that if you remove the Contract.Requires(...) line, the ReSharper message goes away. Update I found the solution through ExternalAnnotations which was also mentioned by Mike below. Here's an example of how to do it for a function in Microsoft.Contracts: Create a directory called Microsoft.Contracts under the ExternalAnnotations ReSharper directory. Next, Create a file called Microsoft.Contracts.xml and populate like so: <assembly name="Microsoft.Contracts"> <member name="M:System.Diagnostics.Contracts.Contract.Requires(System.Boolean)"> <attribute ctor="M:JetBrains.Annotations.AssertionMethodAttribute.#ctor"/> <parameter name="condition"> <attribute ctor="M:JetBrains.Annotations.AssertionConditionAttribute.#ctor(JetBrains.Annotations.AssertionConditionType)"> <argument>0</argument> </attribute> </parameter> </member> </assembly> Restart Visual Studio, and the message goes away!

• Integrating CKFinder with InnovaStudio WYSIWYG Editor

  - by Sonny

  I use InnovaStudio WYSIWYG Editor, and I am trying to replace InnovaStudio's Asset Manager with CKFinder. There's a line in the editor configuration for what URL to use for the asset manager. I have pointed it at CKFinder. The part I can't get to work is getting the field to populate with the double-clicked file's path from CKFinder. It appears to use the 'func' parameter to specify the callback function. The URL I'm calling is: /common/ckfinder/ckfinder.html?action=js&func=setAssetValue The InnovaStudio WYSIWYG Editor provides the setAssetValue(v) callback function for setting the field value. The v parameter should hold the URL. CKFinder pops up as expected when it's invoked, but neither double-clicking the thumbnails nor using the "select" option in the context menu works. The normal/expected behavior is that CKFinder closes and the target field is populated with the URL for the selected asset. Additional Info: The InnovaStudio WYSIWYG Editor has a "popup" for adding an image or flash file to the content. This pop-up is in an iframe. When it calls CKFinder (or it's own asset manager), that is also in an iframe. It appears that CKFinder is looking in the scope of the main window rather than the image/flash iframe that actually contains the field that needs to be populated.

• controller path not found for static images? asp.net mvc routing issue?

  - by rksprst

  I have an image folder stored at ~/Content/Images/ I am loading these images via <img src="/Content/Images/Image.png" /> Recently, the images aren't loading and I am getting the following errors in my error log. What's weird is that some images load fine, while others do not load. Anyone have any idea what is wrong with my routes? Am I missing an ignore route for the /Content/ folder? I am also getting the same error for favicon.ico and a bunch of other image files... <Fatal> -- 3/25/2010 2:32:38 AM -- System.Web.HttpException: The controller for path '/Content/Images/box_bottom.png' could not be found or it does not implement IController. at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(Type controllerType) at System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName) at System.Web.Mvc.MvcHandler.ProcessRequest(HttpContextBase httpContext) at System.Web.Mvc.MvcHandler.ProcessRequest(HttpContext httpContext) at System.Web.Mvc.MvcHandler.System.Web.IHttpHandler.ProcessRequest(HttpContext httpContext) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) My current routes look like this: routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); routes.MapRoute( "ControllerDefault", // Route name "{controller}/project/{projectid}/{action}/{searchid}", // URL with parameters new { controller = "Listen", action = "Index", searchid = "" } // Parameter defaults ); Thanks!

• ASP.NET Membership with two providers cant use GetAllUsers method

  - by Bayonian

  Hi, I'm using two membership providers. When I declared a following statement Dim allUsers As MembershipUserCollection = Membership.Providers("CustomSqlRoleManager").GetAllUsers Then, it gave me this error message. Argument not specified for paramenter 'totalRecords' of 'Public MustOverride Function GetAllUsers(pageIndex as Integer, pageSize as Integer, ByRef totalRecords as Integer) As System.Web.Security.MembershipUserCollection' Then, I added what it asked for like this : Dim allUsers As MembershipUserCollection = Membership.Providers("CustomSqlRoleManager").GetAllUsers(1, 50, 100) I don't get anything in return. I debugged it and allUsers = Nothing. What's wrong the declaration above? Do I really have to provider the paramenters when calling Membership.Providers("CustomSqlRoleManager").GetAllUsers? Update 1 If, I used the statement below: Dim allUsers As MembershipUserCollection = Membership.Providers("MembershipRoleManager").GetAllUsers(0, 0, totalUser) I got this error message: The pageSize must be greater than zero. Parameter name: pageSize. [ArgumentException: The pageSize must be greater than zero. Parameter name: pageSize] System.Web.Security.SqlMembershipProvider.GetAllUsers(Int32 pageIndex, Int32 pageSize, Int32& totalRecords) +1848357 But it works if I provied the pageSize param: Dim pageSize As Integer = GetTotalNumberOfUser() Dim allUsers As MembershipUserCollection = Membership.Providers("MembershipRoleManager").GetAllUsers(0, pageSize, totalUser) This statment Dim pageSize As Integer = GetTotalNumberOfUser() returns the total counted record, it's already round trip to database, just to get the total number of users, because I need to provide the pageSize param value.

• Blank subreport in Jasper Reports

  - by Andy Chapman

  Hi all, I'm trying to launch a report that I created in iReport which contains a main report and a subreport. In iReport, the subreport launches fine and contains data, however when I try to launch it from within my java code, the subreport is blank. What I've done so far: I have a String parameter in the main report called "SUBREPORT" that is used to define the path to the subreport. E.g. value: "E:\java\ReportLauncher\reports\test_subreport1.jasper" The subreport expression in the main report is set to: $P{SUBREPORT} The subreport connection expression is: $P{REPORT_CONNECTION} I also have a subreport parameter defined called "INVOICE_NUMBER" that is set to $F{InviInvNo}, which maps to a field in the main report. In my java code, I have: HashMap<String, Object> paramHash = new HashMap(); paramHash.put("INVOICE_NUMBER", invoiceID); paramHash.put("REPORT_CONNECTION", this.conn); paramHash.put("SUBREPORT", subReportPath); JasperPrint jasperprint = JasperFillManager.fillReport(this.reportPath, paramHash, this.conn); The main report is created fine and is populated. The subreport area however is blank. Any thoughts for what I'm doing wrong? Thanks in advance, Andy.

• Rhino Mocks, Dependency Injection, and Separation of Concerns

  - by whatispunk

  I am new to mocking and dependency injection and need some guidance. My application is using a typical N-Tier architecture where the BLL references the DAL, and the UI references the BLL but not the DAL. Pretty straight forward. Lets say, for example, I have the following classes: class MyDataAccess : IMyDataAccess {} class MyBusinessLogic {} Each exists in a separate assembly. I want to mock MyDataAccess in the tests for MyBusinessLogic. So I added a constructor to the MyBusinessLogic class to take an IMyDataAccess parameter for the dependency injection. But now when I try to create an instance of MyBusinessLogic on the UI layer it requires a reference to the DAL. I thought I could define a default constructor on MyBusinessLogic to set a default IMyDataAccess implementation, but not only does this seem like a codesmell it didn't actually solve the problem. I'd still have a public constructor with IMyDataAccess in the signature. So the UI layer still requires a reference to the DAL in order to compile. One possible solution I am toying with is to create an internal constructor for MyBusinessLogic with the IMyDataAccess parameter. Then I can use an Accessor from the test project to call the constructor. But there's still that smell. What is the common solution here. I must just be doing something wrong. How could I improve the architecture?

• How to call SQL Function with multiple parameters from C# web page

  - by Marshall

  I have an MS SQL function that is called with the following syntax: SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = 7 AND LocationName = ''Default'' ', 10) The first parameter passes a specific WHERE clause that is used by the function for one of the internal queries. When I call this function in the front-end C# page, I need to send parameter values for the individual fields inside of the WHERE clause (in this example, both the ClientID & LocationName fields) The current C# code looks like this: String SQLText = "SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = @ClientID AND LocationName = @LocationName ',10)"; SqlCommand Cmd = new SqlCommand(SQLText, SqlConnection); Cmd.Parameters.Add("@ClientID", SqlDbType.Int).Value = 7; // Insert real ClientID Cmd.Parameters.Add("@LocationName", SqlDbType.NVarChar(20)).Value = "Default"; // Real code uses Location Name from user input SqlDataReader reader = Cmd.ExecuteReader(); When I do this, I get the following code from SQL profiler: exec sp_executesql N'SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable (''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)', N'@ClientID int,@LocationID nvarchar(20)', @ClientID=7,@LocationName=N'Default' When this executes, SQL throws an error that it cannot parse past the first mention of @ClientID stating that the Scalar Variable @ClientID must be defined. If I modify the code to declare the variables first (see below), then I receive an error at the second mention of @ClientID that the variable already exists. exec sp_executesql N'DECLARE @ClientID int; DECLARE @LocationName nvarchar(20); SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable (''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)', N'@ClientID int,@LocationName nvarchar(20)', @ClientID=7,@LocationName=N'Default' I know that this method of adding parameters and calling SQL code from C# works well when I am selecting data from tables, but I am not sure how to embed parameters inside of the ' quote marks for the embedded WHERE clause being passed to the function. Any ideas?

• WPF binding to ComboBox SelectedItem when reference not in ItemsSource.

  - by juharr

  I'm binding the PageMediaSize collection of a PrintQueue to the ItemSource of a ComboBox (This works fine). Then I'm binding the SelectedItem of the ComboBox to the DefaultPrintTicket.PageMediaSize of the PrintQueue. While this will set the selected value to the DefaultPrintTicket.PageMediaSize just fine it does not set the initially selected value of the ComboBox to the initial value of DefaultPrintTicket.PageMediaSize This is because the DefaultPrintTicket.PageMediaSize reference does not match any of the references in the collection. However I don't want it to compare the objects by reference, but instead by value, but PageMediaSize does not override Equals (and I have no control over it). What I'd really like to do is setup a IComparable for the ComboBox to use, but I don't see any way to do that. I've tried to use a Converter, but I would need more than the value and I couldn't figured out how to pass the collection to the ConverterProperty. Any ideas on how to handle this problem. Here's my xaml <ComboBox x:Name="PaperSizeComboBox" ItemsSource="{Binding ElementName=PrintersComboBox, Path=SelectedItem, Converter={StaticResource printQueueToPageSizesConverter}}" SelectedItem="{Binding ElementName=PrintersComboBox, Path=SelectedItem.DefaultPrintTicket.PageMediaSize}" DisplayMemberPath="PageMediaSizeName" Height="22" Margin="120,76,15,0" VerticalAlignment="Top"/> And the code for the converter that gets the PageMediaSize collection public class PrintQueueToPageSizesConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { return value == null ? null : ((PrintQueue)value).GetPrintCapabilities().PageMediaSizeCapability; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } }

• Multiple Conditions in Lambda Expressions at runtime C#

  - by Ryan

  Hi, I would like to know how to be able to make an Expression tree by inputting more than one parameter Example: dataContext.Users.Where(u => u.username == "Username" && u.password == "Password") At the moment the code that I did was the following but would like to make more general in regards whether the condition is OR or AND public Func<TLinqEntity, bool> ANDOnlyParams(string[] paramNames, object[] values) { List<ParameterExpression> paramList = new List<ParameterExpression>(); foreach (string param in paramNames) { paramList.Add(Expression.Parameter(typeof(TLinqEntity), param)); } List<LambdaExpression> lexList = new List<LambdaExpression>(); for (int i = 0; i < paramNames.Length; i++) { if (i == 0) { Expression bodyInner = Expression.Equal( Expression.Property( paramList[i], paramNames[i]), Expression.Constant(values[i])); lexList.Add(Expression.Lambda(bodyInner, paramList[i])); } else { Expression bodyOuter = Expression.And( Expression.Equal( Expression.Property( paramList[i], paramNames[i]), Expression.Constant(values[i])), Expression.Invoke(lexList[i - 1], paramList[i])); lexList.Add(Expression.Lambda(bodyOuter, paramList[i])); } } return ((Expression<Func<TLinqEntity, bool>>)lexList[lexList.Count - 1]).Compile(); } Thanks
