• mx:Tree not dispatching "itemClick" event when click on icon

  - by Xshare

  I have a flex tree that worked perfectly fine when we set the defaultLeafIcon={null} and the folderClosedIcon and folderOpenIcon to {null}. We decided to put the icons back in and took out the nulls. Now they show up fine, but if you click on the icon instead of the label or the rest of the row, it seems to change the selected item, shows the highlight around the new item, but doesn't dispatch the ItemClick event. This makes it really hard to know that the tree's selected item has changed! The weird part is that once you have clicked on the icon once and it looked like the selectedItem changed (or at least it applied that style), if you click the same icon again, it will actually fire the itemClick event. if you click any other icon, it does the same thing again, switching the selectedItem and styling that row, but not firing the itemClick event. Any ideas? Thanks. (This is in flex 4 btw)

• Problem with Validate Anti Forgery

  - by Mikael Egnér

  Hi! I have a problem regarding MVC Anti forgery token. When I do my authentication I have pseudo code like this: var user = userRepository.GetByEmail(email); System.Threading.Thread.CurrentPrincipal = HttpContext.Current.User = user; by doing so I'm able to get the current user in my code like this: var user = HttpContext.Current.User as EntityUser; This works fine until I add the [ValidateAntiForgeryToken] attribute to an action. When I add the attribute I get A required anti-forgery token was not supplied or was invalid. If I comment out this line: System.Threading.Thread.CurrentPrincipal = HttpContext.Current.User = user; The antiforgery validation works fine, but the I don't have my convenient way of getting my "EntityUser" from the HttpContext. Any ideas of how to work around this? Best regards Mikael

• Newbie queston: Cannot load http://localhost/phptest:8080/

  - by Princess Innah

  Hi guys, I decided to learn HTML so I installed apache on windows vista. Everything seems to work fine; when I go to http://localhost:8080 the sample webpage installed by apache shows. Apache is configured at port 8080. So far so good. Since my DocumentRoot is c:\pub, I made another folder inside, e.g., c:\pub\test. What I'm trying to figure out is why the page at http://localhost/test:8080 cannot load? It has index.html and apache is working fine. Any ideas?

• C# setup project output automatically start with administrative rights

  - by Alex

  Hi, i've created an setup project for a .net-application which works fine. The problem is, that the application begins to write log-files after startup and this requires administrative rights on windows vista and windows 7. I know there are some folders which i could use to write into without administrative rights. When i start the application as administrator, everything works fine. I asked myself, if it's possible to change the setup project in visual studio in a way that the installed application automatically owns administrative rights on the target system? Thanks for every help in advance! Alex

• Delphi form icons are blurry on Windows 7's taskbar (with MainFormOnTaskbar enabled)

  - by Dennis G.

  We have a Windows desktop application written in Delphi that works fine on Windows 7, except that the icon of the main form looks blurry in Windows' new taskbar. As long as the application has not been started the icon looks fine (i.e. when it's pinned to the taskbar). Once it has been started Windows uses the icon of the main form (instead of the .exe resource icon) and it's blurry (it looks like a 16x16 version of the icon is scaled up). The icon that we use for the .exe and for the main form are exactly the same and it contains all kinds of resolutions, including 48x48 with alpha blending. My theory is that Delphi ignores/deletes the extra resolutions of the icon when I import the .ico file for the main form in Delphi. Is there a way to prevent/fix this? What's the best way to ensure that an application written in Delphi uses the correct icon resolution in Windows 7's taskbar?

• XSD data set with Oracle database

  - by Ed Woodcock

  Hi folks, I'm having a major issue with an XSD dataset mapping thingy that I'm using within my current project. We are using XSDs for some data abstraction (it's quicker and debatably more maintainable that using Parameterised SQL or a StoredProc), and on my machine (running in the VS development environment) thy're working fine. However, on the Pre-production server we use for our testing, the XSDs are not working correctly: some method calls will fail with the following error: System.ArgumentException: Value does not fall within the expected range. at Oracle.DataAccess.Client.OracleParameter.set_DbType(DbType value) Has anyone ever encountered this issue before? The methods being called are simple select statements using 1-3 parameters, and as I said before they work fine on my machine.

• Is there a certain IIS configuration required to allow a functioning .Net 4.0 ASP.Net MVC 2 Azure ap

  - by erg39

  I just installed the Azure 1.2 tools update and would like to get to work on an Azure project running locally using ASP.Net MVC and .Net 4, but I cannot get MVC pages to load. If I just create a new Azure project in VS 2010, add a ASP.Net MVC web role, and run the application, pages never load. It appears that routing is somehow at fault as controller actions never get called, but if I add other pages to the project (like .htm or .aspx) they will load in the browser. It all works fine with a new project using .Net 3.5, MVC 2 project in the Azure development environment; it all works fine with .Net 4.0 MVC 2 project that is not running in Azure; only the combination does not work. Environment is Win 7 x64 (IIS 7.5), VS 2010, Azure tools 1.2 Is there some magic IIS setting I need to change or something? Any ideas?

• Modifications in default document (ASP.NET+IIS7) won't take effect

  - by Wilson

  We have a website developed by ASP.NET+IIS7 and its default document is default.aspx. It works fine. But when we tried to switch the default to index.html, weird things happened. We have modified web.config as follows: <defaultDocument> <files> <clear /> <add value="index.html" /> </files> </defaultDocument> and we have clear everything under C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files``, and restart the worker process. We even changed the name of Default.aspx to dddd.aspx. But everything stays the same when accessing with http://localhost/<MyAppName>/! And when we tried to access with http://localhost/<MyAppName>/index.html, it works fine. Any suggestions would be highly appreciated.

• White bar at the bottom of root view!

  - by Sam

  Hi, I have two view controllers in the app. When the app starts, the layout of the root view controller's view is just fine. When a button is clicked, the view controller switches to the other one - which shows fine too. However, when the view is switched back to the root view, the contents are shifted UP by about 20 pixels, leaving a white bar at the bottom! - and it was not there when the app had started. Has anyone seen this? Any idea what's going on there? Thanks, Sam.

• Problem running ASP.NET MVC 2 website on IIS7

  - by Charlie

  I'm trying to deploy my ASP.NET MVC 2 website from VS2010 beta 2 to IIS7. The publish works fine but none of the routes work, so when I go to the URL http://localhost/myapp/Home/Index I get the error: HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. I'm deploying to a virtual directory which is using an app pool configured for the .NET 4 framework with managed pipeline mode set to integrated. Also, if I go Basic Settings-Test Connection, both tests pass. From what I understand, it should just work? I don't have any problems deploying Nerd Dinner from VS2008, that works fine.

• Identifying NHibernate proxy classes

  - by Marc Gravell

  I'm not an NHibernate user; I write a serialization utility library. A user has logged a feature-request that I should handle NHibernate proxy classes, treating them the same as the actual type. At the moment my code is treating them as unexpected inheritance, and throwing an exception. The code won't know in advance about NHibernate (including no reference, but I'm not aftaid of reflection ;-p) Is there a robust / guaranteed way of detecting such proxy types? Apparently DataContractSerializer handles this fine, so I'm hoping it is something pretty simple. Perhaps some interface or [attribute] decoration. Also, during deserialization; at the moment I would be creating the original type (not the NHibernate type). Is this fine for persistence purposes? Or is the proxy type required? If the latter; what is required to create an instance of the proxy type?

• How to position an element so that it does not flow off the visible screen

  - by rjray

  I am creating pseudo-tooltips on a page that has a lot of "a" and "span" elements that have these tips associated with them. Everything in the creation of the element is fine, and it displays fine. However, since this is a page with a lot of data, as you get towards the bottom of the visual area the tooltips start to flow past the bottom edge of the window. My initial attempt to compensate for this with window.innerWidth/innerHeight didn't come out too well. I'm using jQuery for DOM manipulation (but not jQuery UI). Given the event itself, and the height and width of the tooltip (which I can get with getBoundingClientRect()), how can I position this element so that the bottom of the tooltip is never below the edge of the window?

• C++: ifstream::getline problem

  - by Jay

  I am reading a file like this: char string[256]; std::ifstream file( "file.txt" ); // open the level file. if ( ! file ) // check if the file loaded fine. { // error } while ( file.getline( string, 256, ' ' ) ) { // handle input } Just for testing purposes, my file is just one line, with a space at the end: 12345 My code first reads the 12345 successfully. But then instead of the loop ending, it reads another string, which seems to be a return/newline. I have saved my file both in gedit and in nano. And I have also outputted it with the Linux cat command, and there is no return on the end. So the file should be fine. Why is my code reading a return/newline? Thanks.

• Nservicebus serization issue of derived types

  - by Tiju John

  Hi Guys, for the context setting, I am exchanging messages between my nServiceBus client and nSerivceBus server. its is the namespace xyz.Messages and and a class, Message : IMessage I have more messages that are in the other dlls, like xyz.Messages.Domain1, xyz.Messages.Domain2, xyz.Messages.Domain3. and messages that derive form that base message, Message. I have the endpoints defined as like : at client <UnicastBusConfig> <MessageEndpointMappings> <add Messages="xyz.Messages" Endpoint="xyzServerQueue" /> <add Messages="xyz.Messages.Domain1" Endpoint="xyzServerQueue" /> <add Messages="xyz.Messages.Domain2" Endpoint="xyzServerQueue" /> </MessageEndpointMappings> </UnicastBusConfig> at Server <UnicastBusConfig> <MessageEndpointMappings> <add Messages="xyz.Messages" Endpoint="xyzClientQueue" /> <add Messages="xyz.Messages.Domain1" Endpoint="xyzClientQueue" /> <add Messages="xyz.Messages.Domain2" Endpoint="xyzClientQueue" /> </MessageEndpointMappings> </UnicastBusConfig> and the bus initialized as IBus serviceBus = Configure.With() .SpringBuilder() .XmlSerializer() .MsmqTransport() .UnicastBus() .LoadMessageHandlers() .CreateBus() .Start(); now when i try sending instance of Message type or any type derived types of Message, it successfully sends the message over and at the server, i get the proper type. eg. Message message= new Message(); Bus.Send(message); // works fine, transfers Message type message = new MessageDerived1(); Bus.Send(message); // works fine, transfers MessageDerived1 type message = new MessageDerived2(); Bus.Send(message); // works fine, transfers MessageDerived2 type My problem arises when any type, say MessageDerived1, contains a member variable of type Message, and when i assign it to a derived type, the type is not properly transferred over the wire. It transfers only as Message type, not the derived type. public class MessageDerived2 : Message { public Message message; } MessageDerived2 messageDerived2= new MessageDerived2(); messageDerived2.message = new MessageDerived1(); message = messageDerived2; Bus.Send(message); // incorrect behaviour, transfers MessageDerived2 correctly, but looses type of MessageDerived2.Message (it deserializes as Message type, instead of MessageDerived1) any help is strongly appreciated. Thanks TJ

• Do i *have* to use ObservableCollection in Silverlight WCF client?

  - by Simon_Weaver

  When accessing Silverlight in WCF you get proxies generated with ObservableCollection Thats fine when you're databinding, but a little clumsy when you're just calling a method. For instance the following service method : [OperationContract] public SearchOrdersMsgOut SearchOrders(ShippingStatusType[] shippingStatuses, string[] orderId) { } gets generated with ObservableCollection. What! They're just parameters. Why would I ever want to 'observe' them? I'm fine if I have to do this - but it seems like there should be a way to force simple array structures when I know I'm never databinding - especially on input messages. I'd much rather do this : searchCriteria.PaymentStatus = new [] { PaymentStatusType.PaymentFailed, PaymentStatusType.Unpaid }; than this : searchCriteria.PaymentStatus = new ObservableCollection<PaymentStatusType> { PaymentStatusType.PaymentFailed, PaymentStatusType.Unpaid }; Is there a way? PS. I do actually use a SearchCriteria object for my search criteria - but I simplified for this example wondering if parameters were handled differently.

• Reloading Rails Directories on Change for Dev: Not Lib!

  - by yar

  I have checked out several questions on this, including all of those you see next to the question. Unfortunately, I'm not working with a plugin, and I don't want to work in lib. I have a directory called File.join(Rails.root, 'classes') and I'd like the classes in this directory to reload automatically in dev. In my environment.rb I have this line config.load_paths << File.join(Rails.root, 'classes') which works fine and blows up if the path isn't there. The reloading line in my development.rb also works fine require_dependency File.join(Rails.root, 'classes', 'blah.rb') which blows up if the file is not there (a good sign). However, the file doesn't reload. This all works if the file is in the root of lib and I use the require_dependency line, but my whole point is to get stuff out of lib as suggested here.

• Flash AS3 and XML: way to fix line breaks in htmlText that uses <b> tags in the xml?

  - by HeroicNate

  I'm importing text in from an xml file and i'm using htmlText to try to keep some styling with tags. I have both the regular and bold face font embedded, and the bolding works fine. The problem is that it ads spaces around the words in bold like a paragraph indent and then makes a line-break after them. What's going on, is there a way to fix? fromxmlText.htmlText = theXML.contenttext; If I pull the text in from a txt file it will work fine, but taking it out of an xml file causing funky formatting. lil' help?

• Web Service in c# - "This web service is using http://tempuri.org/ as its default namespace."

  - by glenatron

  I've created a web service using Visual Studio ( 2005 - I know I'm old school ) and it all compiles fine but when it opens I get warned thus: This web service does not conform to WS-I Basic Profile v1.1. And furthermore: This web service is using http://tempuri.org/ as its default namespace. Which would be fine except my service begins thus: [WebService(Namespace = "http://totally-not-default-uri.com/servicename")] Searching the entire solution folder for "tempuri" returns nothing. I can't find it mentioned in any configuration page acessible from Visual Studio. And yet it's right there in the wsdl:definitions list for the xmlns:tns attribute on the web service descriptor page when I view it through the browser and as targetNamespace in the same tag. I'm viewing it using Visual Studio's "debug" mode with the built in server from that. Seems like something has got cached somewhere but I can't work out what and where- I've tried stopping and restarting the server, cleaning and rebuilding the service and going through the associated text config files with a text editor but no dice. Any idea what is going on?

• multiline gtk.Label ignores xalign=0.5

  - by thomas

  A gtk.Label can't be aligned in center when line-wrap is turned on. Example code: import pygtk pygtk.require('2.0') import gtk class testwin(gtk.Window): def __init__(self): gtk.Window.__init__(self) width,height = 300,300 self.set_size_request(width,height) self.set_position(gtk.WIN_POS_CENTER) self.set_title("test window") label = gtk.Label("test text") label.set_line_wrap(True) label.set_justify(gtk.JUSTIFY_CENTER) label.set_alignment(0.5,0.5) label.connect("size-allocate",lambda l,s: l.set_size_request(s.width-1, -1)) self.add(label) self.connect("destroy", gtk.main_quit) self.show_all() testwin() gtk.main() It looks like this, that means, it's aligned left: http://m45.img-up.net/?up=pic122x97.png If you comment out line 14 (set_line_wrap) everything is perfectly fine: http://o54.img-up.net/?up=pic2y00p9.png Please note that yalign works fine. So it seems like the first argument in the gtk.Misc.set_alignment-function has no effect when line wrap is turned on. Using Fedora 16, 64bit, gtk 3.2.4, pygtk 2.24.0, python 2.7.2 Question: Is this intended or a bug? How is it supposed to be made or is a workaround available?

• MOSS 2007 - Using Connectable WebPart - Consumer has TextBox

  - by JohnP

  I have 2 webparts which are connected, where the provider sends a string to the consumer. However it fails to work if I put any TextBox controls in the consumer webpart. (works fine if I use a Label or Literal control. The idea is that the consumer is to be composed of form controls like TextBoxes. e.g. the codeproject sample at http://www.codeproject.com/KB/sharepoint/ConnectingCustomWebParts.aspx Works fine... until you replace the consumer Label control with a TextBox. Any help gratefully received.

• Why won't my anonymous function fire on grid.prerender?

  - by adam0101

  In my gridview I have fields for inserting a new record in the footer. In my objectdatasource selecting event if no records came back I bind a single mock row to force the footer to show so they can still add records. Since the row does not contain real data I hide the row. ... If result.ItemCount = 0 Then result = mockRow AddHandler mygridview.PreRender, AddressOf HideRow End If End Sub Private Sub HideRow(ByVal sender as Object, ByVal e as EventArgs) mygridview.Rows(0).Visible = False End Sub This works fine. However, I'd like to condense it like this: ... If result.ItemCount = 0 Then result = mockRow AddHandler mygridview.PreRender, Function() mygridview.Rows(0).Visible = False End If End Sub This compiles fine, but the row doesn't get hidden. Can anyone tell me why my anonymous function isn't getting hit?

• .odx Files in BizTalk 2009 (VS2008 IDE) Fail to open. "Unspecified Error"

  - by AllenG

  Okay, I'm not sure if this is an SO question, or a ServerFault question, but I figured I'd post here first. I have a BizTalk project which works like a champ for its original design. It's been deployed and it's working fine. Today, I went in to add some new fuctionality by modifying one of my orchestrations. When I attempted to open it, I got a message which simply stated: "The operation could not be completed. Unspecified error." I've closed the IDE and re-opened; I've restarted the machine; I've even allowed Microsoft Updates to run and restart the machine. Everything else opens just fine (.xsd files, .btms, etc.) so it appears only to be the orchestrations which are failing. Has anyone ever encountered a similar issue and resolved it (short of reinstalling BizTalk/VS, or blowing the orchs away and rebuilding)? Any help would be appreciated.

• Allow native DLL to output stdout / stderr in c# console application

  - by xaw

  I have a native DLL which outputs via stdout / stderr. I have a C# console application which calls this DLL and outputs binary data to a parent C# application which started the C# console exe, processing stdout / stderr. Currently when I call the C# exe it works just fine (the DLL hooks up to the stdout of my console application and puts its data in just fine). Is this by design (and shouldn't be broken in future .NET framework versions)? Are there limitations on my managed code's deployment with this strategy (full-trust, permission requirements, GAC issues, etc)? I can't seem to find any documentation about stdout with a managed exe and an unmanaged dll both putting data in that standard output on MSDN. Thanks,

• .net Studio Local Database

  - by testerwpf

  Hello everyone, i am designing a local database in .net with wpf as gui. I have added a new database, and added a new table. Through the TableAdapter i generated 2 statements ( 1 statement is a select stmt and 1 is a insert) , i insert name and firstname (id is auto generated). It works fine, i can display the table in a datagrid (wpf toolkit) and also add new items (name,firstname), when i close and start the application everything is fine (data in table is stored) BUT when i try to preview data in my database dataset (where my Adapters exist) , no data is displayed and then the table gets deleted.. why? public partial class MainWindow : Window { public MainWindow() { this.InitializeComponent(); PlayerTableAdapter objPlayerTableAdapter = new PlayerTableAdapter(); objDataGridResults.ItemsSource = objPlayerTableAdapter.GetDataAllPlayer(); } //Button Event onClick private void m_voidAddPlayer(object sender, System.Windows.RoutedEventArgs e) { PlayerTableAdapter objPlayerTableAdapter = new PlayerTableAdapter(); objPlayerTableAdapter.InsertQueryPlayer(objTextBoxPlayerName.Text.ToString(), objTextBoxPlayerFirstName.Text.ToString()); objDataGridResults.ItemsSource = objPlayerTableAdapter.GetDataAllPlayer(); } }

• Response.Redirect() will not redirect on Internet Explorer

  - by Amit

  Hi, I am using Response.Redirect("someurl",true); in the page_preInit event to redirect all the requests that come to a page. It works fine on Firexox, but if i access the page from internet explorer 7/8, it says page can not be found and will not redirect to new URL. Any idea why this happens?? Update: I tried giving a radom URL in the redirect such as google.com and it works fine. Actually the URL I am trying to redirect is not accessible on my machine, it is on another VPN. I guess IE will not change the URL on the addressbar if it can not access the URL. Firefox on the other hand changes the address on the address bar.
