  • How to convert this code-based WPF tooltip to Silverlight?

    - by Edward Tanguay
    The following ToolTip code works in WPF. I'm trying to get it to work in Silverlight. But it gives me these errors: TextBlock does not contain a definition for ToolTip. Cursors does not contain a definition for Help. ToolTipService does not contain a definition for SetInitialShowDelay. How can I get this to work in Silverlight? using System.Windows; using System.Windows.Controls; using System.Windows.Input; using System.Windows.Media; namespace TestHover29282 { public partial class Window1 : Window { public Window1() { InitializeComponent(); AddCustomer("Jim Smith"); AddCustomer("Joe Jones"); AddCustomer("Angie Jones"); AddCustomer("Josh Smith"); } void AddCustomer(string name) { TextBlock tb = new TextBlock(); tb.Text = name; ToolTip tt = new ToolTip(); tt.Content = "This is some info on " + name + "."; tb.ToolTip = tt; tt.Cursor = Cursors.Help; ToolTipService.SetInitialShowDelay(tb, 0); MainStackPanel.Children.Add(tb); } } }

  • Mark assembly App_licenses.dll with AssemblyVersion (FxCop CA1016 rule)

    - by user295479
    Hello everyone, I'm trying to fulfil FxCop's rules in my web site. Since I use some Infragistics controls I have a licenses.licx file that turns into a "app_licenses.dll" assembly after publication. The problem is that this app_licenses.dll assembly does not comply with rule CA1016 (MarkAssembliesWithAssemblyVersion), and I should add an AssemblyVersion attribute to 'App_Licenses.dll'. I found I can add an AssemblyInfo file to my web site and then reference it from the web.config file as following: <compilers> <compiler language="c#;cs;csharp" extension=".cs" compilerOptions="C:\....\AssemblyInfo.cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4"> <providerOption name="CompilerVersion" value="v3.5" /> <providerOption name="WarnAsError" value="false" /> </compiler> </compilers> AssemblyInfo.cs contains: using System; using System.Reflection; using System.Runtime.InteropServices; using System.Resources; [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")] [assembly: NeutralResourcesLanguageAttribute("es-ES")] NeutralResourcesLanguageAttribute worked for another auto-generated dll in the web site (app_GlobalResources.dll) for another FxCop rule, but app_licenses.dll seems to ignore the assembly info and still pops up the same CA1016 error. Any help would be much appreciated.

  • How to know about MySQL 'refused connections'

    - by celalo
    Hello, I am using MONyog to montitor my two mysql servers. I get alert emails from MONyog when something goes wrong. There is an error I could not find out why. It says: Connection History: Percentage of refused connections) - 66.67% the percentage is not important, this is just about having refused connections. I get this email every half an hour. So this is like a constant situation. This must be my mistake, because I just set up those servers and there is no chance somebody else could be interfering the servers. MONyog advices me: Try to isolate users/applications that are using an incorrect password or trying to connect from unauthorized hosts. A client will be disallowed to connect if it takes more than connect_timeout seconds to connect. Set the value of log_warnings system variable to 2. This will force the MySQL server to log further information about the error. I added log_warnings=2 to my.cnf and I enabled logging like this: [mysqld_safe] . . log_warnings=2 log-error = /var/log/mysql/error.log . . . . [mysqld_safe] . log-error=/var/log/mysqld.log . . I cannot see any warnings at /var/log/mysql/error.log I can see some warnings at /var/log/mysqld.log but they are about something else. In sum, my question is how can I detect refused connections? Please let me know if any more info is required. Thanks in advance.

  • Spring HandlerInterceptor or Spring Security to protect resource

    - by richever
    I've got a basic Spring Security 3 set up using my own login page. My configuration is below. I have the login and sign up page accessible to all as well as most everything else. I'm new to Spring Security and understand that if a user is trying to access a protected resource they will be taken to the defined login page. And upon successful login they are taken to some other page, home in my case. I want to keep the latter behavior; however, I'd like specify that if a user tries to access certain resources they are taken to the sign up page, not the login page. Currently, in my annotated controllers I check the security context to see if the user is logged in and if not I redirect them to the sign up page. I only do this currently with two urls and no others. This seemed redundant so I tried creating a HandlerInterceptor to redirect for these requests but realized that with annotations, you can't specify specific requests to be handled - they all are. So I'm wondering if there is some way to implement this type of specific url handling in Spring Security, or is going the HandlerInterceptor route my only option? Thanks! <http auto-config="true" use-expressions="true"> <intercept-url pattern="/login*" access="permitAll"/> <intercept-url pattern="/signup*" access="permitAll"/> <intercept-url pattern="/static/**" filters="none" /> <intercept-url pattern="/" access="permitAll"/> <form-login login-page="/login" default-target-url="/home"/> <logout logout-success-url="/home"/> <anonymous/> <remember-me/> </http>

  • Is this a bug? : I get " The type ... is not a complex type or an entity type" in my WCF data servic

    - by veertien
    When invoking a query on the data service I get this error message inside the XML feed: <m:error> <m:code></m:code> <m:message xml:lang="nl-NL">Internal Server Error. The type 'MyType' is not a complex type or an entity type.</m:message> </m:error> When I use the example described here in the article "How to: Create a Data Service Using the Reflection Provider (WCF Data Services)" http://msdn.microsoft.com/en-us/library/dd728281(v=VS.100).aspx it works as expected. I have created the service in a .NET 4.0 web project. My data context class returns a query object that is derived from the LINQExtender (http://linqextender.codeplex.com/). When I execute the query object in a unit test, it works as expected. My entity type is defined as: [DataServiceKey("Id")] public class Accommodation { [UniqueIdentifier] [OriginalFieldName("EntityId")] public string Id { get; set; } [OriginalFieldName("AccoName")] public string Name { get; set; } } (the UniqueIdentifier and OriginalFieldName attributes are used by LINQExtender) Does anybody know if this is a bug in WCF data services or am I doing something wrong?

  • Understanding Javascript's difference between calling a function, and returning the function but executing it later.

    - by Squeegy
    I'm trying to understand the difference between foo.bar() and var fn = foo.bar; fn(); I've put together a little example, but I dont totally understand why the failing ones actually fail. var Dog = function() { this.bark = "Arf"; }; Dog.prototype.woof = function() { $('ul').append('<li>'+ this.bark +'</li>'); }; var dog = new Dog(); // works, obviously dog.woof(); // works (dog.woof)(); // FAILS var fnWoof = dog.woof; fnWoof(); // works setTimeout(function() { dog.woof(); }, 0); // FAILS setTimeout(dog.woof, 0); Which produces: Arf Arf undefined Arf undefined On JSFiddle: http://jsfiddle.net/D6Vdg/1/ So it appears that snapping off a function causes it to remove it's context. Ok. But why then does (dog.woof)(); work? It's all just a bit confusing figuring out whats going on here. There are obviously some core semantics I'm just not getting.

  • simpletest - Why does setReturnValue() seem to change behaviour depending on if test is run in isola

    - by JW
    I am using SimpleTest version 1.0.1 for a unit test. I create a new mock object within a test method and on it i do: $MockDbAdaptor->setReturnValue('query',1); Now, when i run this in a standalone unit test my tested object is happy to see 1 returned when query() is called on the mock db adaptor. However, when this exact same test is run as part of my 'all_tests' TestSuite, the test is failing. This happens because a call to the mock's query() method does not appear to return any value - thus causing my test subject to complain and trigger an unexpected exception that fails the test. So, the behaviour of setReturnValue() seems to change depending on whether the test is run in isolation or not. I can get it to work in both a standalone and TestSuite contexts by using this instead: $MockDbAdaptor->setReturnValueAt(0,'query',1); So my immediate problem can be fixed ...but it feels like a hack. I thought if i create a new mock within a test method then why is the setReturnValue() behaviour getting affected by the context in which the test class instance is run? It feel like a bug.

  • Visual Studio code metrics misreporting lines of code

    - by Ian Newson
    The code metrics analyser in Visual Studio, as well as the code metrics power tool, report the number of lines of code in the TestMethod method of the following code as 8. At the most, I would expect it to report lines of code as 3. [TestClass] public class UnitTest1 { private void Test(out string str) { str = null; } [TestMethod] public void TestMethod() { var mock = new Mock<UnitTest1>(); string str; mock.Verify(m => m.Test(out str)); } } Can anyone explain why this is the case? Further info After a little more digging I've found that removing the out parameter from the Test method and updating the test code causes LOC to be reported as 2, which I believe is correct. The addition of out causes the jump, so it's not because of braces or attributes. Decompiling the DLL with dotPeek reveals a fair amount of additional code generated because of the out parameter which could be considered 8 LOC, but removing the parameter and decompiling also reveals generated code, which could be considered 5 LOC, so it's not simply a matter of VS counting compiler generated code (which I don't believe it should do anyway).

  • Where should I declare my CDI resources?

    - by Laird Nelson
    JSR-299 (CDI) introduces the (unfortunately named) concept of a resource: http://docs.jboss.org/weld/reference/1.0.0/en-US/html/resources.html#d0e4373 You can think of a resource in this nomenclature as a bridge between the Java EE 6 brand of dependency injection (@EJB, @Resource, @PersistenceContext and the like) and CDI's brand of dependency injection. The general gist seems to be that somewhere (and this will be the root of my question) you declare what amounts to a bridge class: it contains fields annotated both with Java EE's @EJB or @PersistenceContext or @Resource annotations and with CDI's @Produces annotations. The net effect is that Java EE 6 injects a persistence context, say, where it's called for, and CDI recognizes that injected PersistenceContext as a source for future injections down the line (handled by @Inject). My question is: what is the community's consensus--or is there one--on: what this bridge class should be named where this bridge class should live whether it's best to localize all this stuff into one class or make several of them ...? Left to my own devices, I was thinking of declaring a single class called CDIResources and using that as the One True Place to link Java EE's DI with CDI's DI. Many examples do something similar, but I'm not clear on whether they're "just" examples or whether that's a good way to do it. Thanks.

  • Android ListView appears empty, but contains objects

    - by Lethjakman
    I'm having a really odd problem with my android listview. The listview is inside of a fragment, everything's compiling and I'm no longer getting a nullpointer error, but the listview is appearing empty. Even though it's appearing empty, the log is stating that the listview has 385 objects. I can't figure out why it's empty. I do get a blue fragment, and the listview is populated. Any ideas? How I set the adapter: ActivePackages = getList(); LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); LinearLayout mContainer = (LinearLayout) inflater.inflate(R.layout.tab_frag1_layout, null); ListView activeList = (ListView) mContainer.findViewById(R.id.activelist); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, ActivePackages); Log.i("valueof activeList",String.valueOf(activeList.getCount())); //returns 0 activeList.setAdapter(adapter); adapter.notifyDataSetChanged(); Log.i("valueof activeList",String.valueOf(activeList.getCount())); //returns 385. This is the xml for the fragment: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ListView android:id="@+id/activelist" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#0073fd"> </ListView> </LinearLayout>

  • Databinding in WinForms performing async data import

    - by burnside
    I have a scenario where I have a collection of objects bound to a datagrid in winforms. If a user drags and drops an item on to the grid, I need to add a placeholder row into the grid and kick off a lengthy async import process. I need to communicate the status of the async import process back to the UI, updating the row in the grid and have the UI remain responsive to allow the user to edit the other rows. What's the best practice for doing this? My current solution is: binding a thread safe implementation of BindingList to the grid, filled with the objects that are displayed as rows in the grid. When a user drags and drops an item on to the grid, I create a new object containing the sparse info obtained from the dropped item and add that to the BindingList, disabling the editing of that row. I then fire off a separate thread to do the import, passing it the newly bound object I have just created to fill with data. The import process, periodically sets the status of the object and fires an event which is subscribed to by the UI telling it to refresh the grid to see the new properties on the object. Should I be passing the same object that is bound to the grid to the import process thread to operate on, or should I be creating a copy and merging back the changes to the object on the UI thread using BeginInvoke? Any problems or advice with this implementation? Thanks

  • setAnimationRepeatAutoreverses not behaved as I expected

    - by danielkwan
    I am starting to learn to use UIView animation. So I wrote the following lines: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2.0]; [UIView setAnimationRepeatCount:2]; [UIView setAnimationRepeatAutoreverses:YES]; CGPoint position = greenView.center; position.y = position.y + 100.0f; position.x = position.x + 100.0f; greenView.center = position; [UIView commitAnimations]; In this case, the UIView (a green box) moved back and fore 2 times. So far so good, BUT I found out that after the moving twice, the green box ended up jumped to the "new position" (position.x + 100.0f, position.y + 100.0f) instead of going back to the original position (position.x, position.y). That makes the animation look pretty odd (like after the box swing back to the original position caused by setAnimationRepeatAutoreverses, it jumps back to the new position in the last microsecond!) What is the best way to make the green box NOT jump to the new position at the very last minute?

  • doublechecking: no db-wide 'unicode switch' for sql server in the foreseeable future, i.e. like Orac

    - by user72150
    Hi all, I believe I know the answer to this question, but wanted to confirm: Question Does Sql server (or will it in the foreseeable future), offer a database-wide "unicode switch" which says "store all characters in unicode (UTF-16, UCS-2, etc)", i.e. like Oracle. The Context Our application has provided "CJK" (Chinese-Japanese-Korean) support for years--using Oracle as the db store. Recently folks have been asking for the same support in sql server. We store our db schema definition in xml and generate the vendor-specific definitions (oracle, sql server) using vendor-specific xsl. We can make the change easily. The problem is for upgrades. Generated scripts would need to change the column types for 100+ columns from varchar to nvarchar, varchar(max) to nvarchar(max), etc. These changes require dropping and recreating indexes and foreign keys if the any indexes/fk's exist on the column. Non-trivial. Risky. DB-wide character encodings for us would eliminate programming changes. (I.e. we would not to change the column types from varchar to nvarchar; sql server would correctly store unicode data in varchar columns). I had thought that eventually sql server would "see the light" and allow storing unicode in varchar/clob columns. Evidently not yet. Recap So just to triple check: does mssql offer a database-wide switch for character encoding? Will it in SQL2008R3? or 2010? thanks, bill

  • [iPhone] Background color during flip view animation/transition?

    - by Rob S.
    I have some pretty standing flipping action going on: [UIView beginAnimations:@"swapScreens" context:nil]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; [UIView setAnimationDuration:1.0]; [self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1]; [UIView commitAnimations]; To Apple's credit, this style of animation is amazingly easy to work with. Very cool, and I've been able to animate transitions, flips, fades etc. throughout the app very easily. Question: During the flip transition, the background visible 'behind' the two views during the flip is white and I'd like it to be black. I've: Set the background of the containing view (self.view above) - no dice. I really thought that would work. Set the background of each view to black - no dice. I didn't think this would work although you give different things a shot to understand better :) Google'd like crazy; keep landing on Safari-related listings. Thanks in advance!

  • Pass table as parameter to SQLCLR TV-UDF

    - by Skeolan
    We have a third-party DLL that can operate on a DataTable of source information and generate some useful values, and we're trying to hook it up through SQLCLR to be callable as a table-valued UDF in SQL Server 2008. Taking the concept here one step further, I would like to program a CLR Table-Valued Function that operates on a table of source data from the DB. I'm pretty sure I understand what needs to happen on the T-SQL side of things; but, what should the method signature look like in the .NET (C#) code? What would be the parameter datatype for "table data from SQL Server?" e.g. /* Setup */ CREATE TYPE InTableType AS TABLE (LocationName VARCHAR(50), Lat FLOAT, Lon FLOAT) GO CREATE TYPE OutTableType AS TABLE (LocationName VARCHAR(50), NeighborName VARCHAR(50), Distance FLOAT) GO CREATE ASSEMBLY myCLRAssembly FROM 'D:\assemblies\myCLR_UDFs.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS GO CREATE FUNCTION GetDistances(@locations InTableType) RETURNS OutTableType AS EXTERNAL NAME myCLRAssembly.GeoDistance.SQLCLRInitMethod GO /* Execution */ DECLARE @myTable InTableType INSERT INTO @myTable(LocationName, Lat, Lon) VALUES('aaa', -50.0, -20.0) INSERT INTO @myTable(LocationName, Lat, Lon) VALUES('bbb', -20.0, -50.0) SELECT * FROM @myTable DECLARE @myResult OutTableType INSERT INTO @myResult MyCLRTVFunction @myTable --returns a table result calculated using the input The lat/lon - distance thing is a silly example that should of course be better handled entirely in SQL; but I hope it illustrates the general intent of table-in - table-out through a table-valued UDF tied to a SQLCLR assembly. I am not certain this is possible; what would the SQLCLRInitMethod method signature look like in the C#? public class GeoDistance { [SqlFunction(FillRowMethodName = "FillRow")] public static IEnumerable SQLCLRInitMethod(<appropriateType> myInputData) { //... } public static void FillRow(...) { //... } } If it's not possible, I know I can use a "context connection=true" SQL connection within the C# code to have the CLR component query for the necessary data given the relevant keys; but that's sensitive to changes in the DB schema. So I hope to just have SQL bundle up all the source data and pass it to the function. Bonus question - assuming this works at all, would it also work with more than one input table?

  • AssemblyLoadException in postsharp, problem with arguments from referenced DLLs?

    - by RodH257
    I'm just starting out with postsharp/AOP. I want to make some instrumentation for C# to track the usage of some addins that I write for a peice of software. I am trying to use the OnMethodBoundaryAspect class to take note of the values of some of the parameters when the method is called. Those parameters are types which are referenced in an external DLL. When I add my attribute to the method, the project won't build, I get the following error Error 2 Unhandled exception (2.0.5.1204, 64 bit, CLR 2.0, Release): PostSharp.CodeModel.AssemblyLoadException: Error while loading the assembly "C:\Program Files\Autodesk\Revit Structure 2011\Program\RevitAPI.dll": Could not load file or assembly 'revitapi, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) The REvitAPI.dll is the file with the type in it. I've also tested just adding the attribute to the project but not applying it to any methods, this also causes the error. So it appears its not related to the method parameter types itself, but merely the existence of this DLL. Has anyone come across this issue before, or can anyone point me in the right direction of where to get some more info on this?

    - by Adrian Grigore
    Hi, I'd like to implement a REST api to an existing ASP.NET MVC website. I've managed to set up WCF Data services so that I can browse my data, but now the question is how to handle authentication. Right now the data service is secured via the site's built in forms authentication, and that's ok when accessing the service from AJAX forms. However, It's not ideal for a RESTful api. What I would like as an alternative to forms authentication is for the users to simply embed the user name and password into the url to the web service or as request parameters. For example, if my web service is usually accessible as http://localhost:1234/api.svc I'd like to be able to access it using the url http://localhost:1234/api.svc/{login}/{password} So, my questions are as follows: Is this a sane approach? If yes, how can I implement this? It seems trivial redirecting GET requests so that the login and password are attached as GET parameters. I also know how to inspect the http context and use those parameters to filter the results. But I am not sure if / how the same approach could be applied to POST, PUT and DELETE requests. Thanks, Adrian

  • Nested dereferencing arrows in Perl: to omit or not to omit?

    - by DVK
    In Perl, when you have a nested data structure, it is permissible to omit de-referencing arrows to 2d and more level of nesting. In other words, the following two syntaxes are identical: my $hash_ref = { 1 => [ 11, 12, 13 ], 3 => [31, 32] }; my $elem1 = $hash_ref->{1}->[1]; my $elem2 = $hash_ref->{1}[1]; # exactly the same as above Now, my question is, is there a good reason to choose one style over the other? It seems to be a popular bone of stylistic contention (Just on SO, I accidentally bumped into this and this in the space of 5 minutes). So far, none of the usual suspects says anything definitive: perldoc merely says "you are free to omit the pointer dereferencing arrow". Conway's "Perl Best Practices" says "whenever possible, dereference with arrows", but it appears to only apply to the context of dereferencing the main reference, not optional arrows on 2d level of nested data structures. "MAstering Perl for Bioinfirmatics" author James Tisdall doesn't give very solid preference either: "The sharp-witted reader may have noticed that we seem to be omitting arrow operators between array subscripts. (After all, these are anonymous arrays of anonymous arrays of anonymous arrays, etc., so shouldn't they be written [$array-[$i]-[$j]-[$k]?) Perl allows this; only the arrow operator between the variable name and the first array subscript is required. It make things easier on the eyes and helps avoid carpal tunnel syndrome. On the other hand, you may prefer to keep the dereferencing arrows in place, to make it clear you are dealing with references. Your choice." Personally, i'm on the side of "always put arrows in, since itg's more readable and obvious tiy're dealing with a reference".

  • XML RPC c# Call returns array of strings and int

    - by chillconsulting
    I'm doing an XML RPC call in ASP.net with c# and the call returns an Array called userinfo with strings and integers in it and I can't seem to figure out how to parse the data and put it into string and int objects... The only thing that compiles is if I make it an Object in the struct. The int returns fines and is referenced easily. Any help would be appreciated - this is what I got. public Page_Load(object sender, EventArgs e){ IValidateSSO proxy = XmlRpcProxyGen.Create<IValidateSSO>(); UserInfoSSOValue ret2 = proxy.UserInfoSSO(ssoAuth, ssoValue); int i = ret2.isonid; } public struct UserInfoSSOValue { public Object userinfo; public int isonid; } [XmlRpcUrl("host")] public interface IValidateSSO : IXmlRpcProxy { [XmlRpcMethod("sso.session_userinfo")] UserInfoSSOValue UserInfoSSO(string ssoauth, string sid); } Here is what the xml rpc calls returns (I know it's in php... I'm trying to implement in c#): sso.session_userinfo(string $ssoauth, string $sid) string $ssoauth - authentication string (assigned by ONID support) string $sid - sid to get info on Returns: Array ( [userinfo] => Array ( [lastname] => College [expire_time] => 1118688011 [osuuid] => 12345678901 [sid_length] => 3600 [ip] => 10.0.0.1 [sid] => WiT7ppAEUKS3rJ2lNz3Ue64sGPxnnLL0 [username] => collegej [firstname] => Joe [fullname] => College, Joe Student [email] => [email protected] [create_time] => 1118684410 ) [isonid] => 1 ) array userinfo - array containing basic user information

  • Is an LSA MSV1_0 subauthentication package needed for some impersonation use cases?

    - by Chris Sears
    Greetings, I'm working with a vendor who has implemented some code that uses a Windows LSA MSV1_0 subauthentication package (MSDN info if you're interested: http://msdn.microsoft.com/en-us/library/aa374786(VS.85).aspx ) and I'm trying to figure out if it's necessary. As far as I can tell, the subauthentication routine and filter allow for hooking or customizing the standard LSA MSV1_0 logon event processing. The issue is that I don't understand why the vendor's product would need these capabilities. I've asked them and they said they use it to perform impersonation. The product definitely does need to do impersonation, but based on my limited win32 knowledge, they could get the functionality they need using the normal auth APIs (LsaLogonUser, ImpersonateLoggedOnUser, etc) without the subauthentication package. Furthermore, I've worked with a number of similar products that all do impersonation, and this is the only one that's used a subauthentication package. If you're wondering why I would care, a previous version of the product had a bug in the subauthentication package dll that would cause lockups or bluescreens. That makes me rather nervous and has me questioning the use of such a low-level, kernel sensitive interface. I'd like to go back to the vendor and say "There's no way you could need an LSA subauth package for impersonation - take it out", but I'm not sure I understand the use cases and possible limitations of the standard win32 authentication/impersonation APIs well enough to make that claim definitively. So, to the win32 security gurus out there, is there any reason you would need an LSA MSV1_0 subauthentication package if all you were doing is impersonation? Thanks in advance for any thoughts!

  • Test Ruby-on-Rails controller with RSpec and different route name

    - by jhwist
    I have a Rails model named Xpmodule with a corresponding controller XpmoduleController. class XpmoduleController < ApplicationController def index @xpmodule = Xpmodule.find(params[:module_id]) end def subscribe flash[:notice] = "You are now subscribed to #{params[:subscription][:title]}" redirect_to :action => :index end end The original intent was to name the model Module which for obvious reasons doesn't work. However I still want to have the URLs look like /module/4711/ therefore I added this to my routes.rb: map.connect '/module/:module_id', :controller => 'xpmodule', :action => 'index' map.connect '/module/:module_id/subscribe', :controller => 'xpmodule', :action => 'subscribe' Now I want to test this controller with Rspec: describe XpmoduleController do fixtures :xpmodules context "index" do it "should assign the current xpmodule" do xpm = mock_model(Xpmodule) Xpmodule.should_receive(:find).and_return(xpm) get "index" assigns[:xpmodule].should be_an_instance_of(Xpmodule) end end end for which I get No route matches {:action=>"index", :controller=>"xpmodule"}. Which of course is sort-of right, but I don't want to add this route just for testing purposes. Is there a way to tell Rspec to call a different URL in get?

  • Embedding a File Explorer instance in a WinForms app form

    - by Unsliced
    My (C#, .NET 3.5) app generates files and, in addition to raising events that can be caught and reacted to, I want to display the target folder to the user in a form. The file-list is being shown within the same form as other information. I'm using an instance of the WebBrowser control (System.Windows.Forms.WebBrowser), then navigating to the folder. This shows some default view of the explorer window, with the file summary panel on the left and the files in the 'Tiles' (large icon and text) view. e.g. wb.Navigate(@"c:\path\to\folder\"); I'd like to suppress the panel and to view the file list in the Details view. The user can get to this via a right-click, context menu, but I'd like it to come up automatically. I'd rather not have to build my own TreeView, DataGridView or whatever; the WebBrowser control does all the updating and re-sorting and whatnot 'for free'. Does anybody have a better suggestion? A different control to use or some additional arguments to pass to the control? And if I could trap events (e.g. files being selected/renamed/double-clicked, etc.) then all the better!
