• Locating binding errors

  - by softengine

  I'm dealing with a large WPF application that is outputting a large number of binding errors. A typical error looks like this: System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.ItemsControl', AncestorLevel='1''. BindingExpression:Path=HorizontalContentAlignment; DataItem=null; target element is 'MenuItem' (Name=''); target property is 'HorizontalContentAlignment' (type 'HorizontalAlignment') Problem is I don't know where in the app this is coming from. Searching the entire solution for AncestorType={x:Type ItemsControl} doesn't necessary help since I still don't know which result is the culprit. I've tried setting PresentationTraceSources.DataBindingSource.Switch.Level = SourceLevels.All; but the extra information doesn't help locate the problematic bindings. File names and line numbers is really what I need. Is there anyway to get this information?

• java runtime 6 with socks v5 proxy - Possible?

  - by rwired

  I have written an application that (amongst other things) runs a local service in windows that acts as a SOCKS v5 proxy for Firefox. I'm in the debugging phase right now and have found certain websites that don't work correctly. For example the Java Applet for Picture Uploading on Facebook.com fails because is is unable to lookup domains. My app overrides a hidden FF config setting network.proxy.socks__remote__dns setting it to true. The whole purpose of the app is to allow access to websites when behind a firewall (e.g. if the user is in China), so this setting is essential to ensure domains are resolved remotely also (and not just HTTP requests). In the JRE6 settings (documented here) there isn't an equivalent setting, and since remote DNS resolution is a feature of SOCKS v5 and not v4 as the documentation seems to imply I'm worried that it's just not possible. How can I programmatically make sure the JRE uses a SOCKS v5 proxy for all requests (including DNS)? UPDATE: Steps to reproduce this problem: Make sure you are behind a firewall that blocks (or redirects) internet access including DNS Install PuTTY and add a dynamic SSH tunnel on some port number of your choice (e.g. 9870). Then login to a remote server that has full access to the internet Launch Firefox and you will not be able to browse the web In FF network settings set the SOCKS v5 proxy to localhost:9870 In FF go to about:config, change network.proxy.socks__remote__dns to true You will now be able to browse the web. Go to facebook.com, login, go to your profile and attempt to use the picture uploader java applet to add some pictures It will fail with a series of class not found errors looking similar to: load: class com.facebook.facebookphotouploader5.FacebookPhotoUploader5.class not found. I believe this is failing because the JRE is unable to resolve the domain that the class resides on. I'm basing this belief on the fact that the documentation (http://java.sun.com/javase/6/docs/technotes/guides/deployment/deployment-guide/properties.html) talks only about SOCKS v4 (which as far as I know does not support remote DNS). My deployment.properties file is located in %APPDATA%\Sun\Java\Deployment. I can confirm that modifications I make in the Java Control Panel get written into that file. If instead of "Use browser setting" the network settings for Java I override and attempt to use the SOCKS proxy settings manually, I still have the issue. There does not seem to be an easy way to force the JRE to do DNS remotely through the Proxy. UPDATE 2: Without the SOCKS proxy, from my local client www.facebook.com resolves to 203.161.230.171 upload.facebook.com resolves to 64.33.88.161 Neither host is reachable (because of the firewall) If I login to the remote server, I get: www.facebook.com 69.63.187.17 upload.facebook.com 69.63.178.32 Both these IPs change after a few minutes, as it seems Facebook uses round-robin DNS and other load-balancing. With the Proxy settings set in Firefox, I can navigate to www.facebook.com without any difficulty (since DNS is being resolved remotely on the Proxy). Whey I go to the page with the Java applet it fails with the stacktrace messages I've already reported. However if I edit Windows\System32\drivers\etc\hosts, adding the correct IP for upload.facebook.com I can get the applet to load and work correctly (restart of FF is sometimes necessary). This evidence seems to support my theory that the Java Runtime is not resolving DNS on the Proxy, but instead just routing traffic though it. My application is for mass-deployment, and needs to work with java applets on other sites (not just facebook). I really need a work-around for this problem. UPDATE 3 Stacktrace dump a requested by ZZ Coder: load: class com.facebook.facebookphotouploader5.FacebookPhotoUploader5.class not found. java.lang.ClassNotFoundException: com.facebook.facebookphotouploader5.FacebookPhotoUploader5.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.net.SocketException: Connection reset at java.net.SocketInputStream.read(Unknown Source) at java.io.BufferedInputStream.fill(Unknown Source) at java.io.BufferedInputStream.read1(Unknown Source) at java.io.BufferedInputStream.read(Unknown Source) at sun.net.www.http.HttpClient.parseHTTPHeader(Unknown Source) at sun.net.www.http.HttpClient.parseHTTP(Unknown Source) at sun.net.www.http.HttpClient.parseHTTP(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Exception: java.lang.ClassNotFoundException: com.facebook.facebookphotouploader5.FacebookPhotoUploader5.class Dumping class loader cache...

• Winforms: Enabling Localization by default (enforcing a project/solution policy)

  - by Obalix

  Is there an easy way to set the Localizable property to true for newly created usercontrols / forms? The scope of the setting should ideally be a solution or a project. In other words I want to say that this project/solution should be localizable, and then if I add a new form or control VS should automatically set the property to true. Edit: Although custom templates are possible, in a larger team they might not be always used. So it's more about enforcing a policy, ensuring that the team members do not ommit to set the property for the projects/solutions where it is a requirement that all forms/controls containing text resources should be localizable. Note: Team Foundation Server is not an Option.

• Why does Silverlight 4 Tools only give partial intellisense?

  - by Edward Tanguay

  I finally got Silverlight 4 Toolkit installed , referenced and working after the difficulty of finding the right namespace described in this question. But intellisense doesn't work fully: after I type "tk:", it doesn't pop up the various controls I have available, but if I type a control name out, e.g. DockPanel, then it works, as shown below. It will even give me intellisense after I type tk:DropPanel, which is odd. How can I get intellisense to work in all cases for the Silverlight 4 Toolkit? I can imagine I need another namespace, but this site says that this reference: is now all you need (and will be automatically used by both Visual Studio and Blend)

• C# WinForms & SQL bindings

  - by vent

  I have a MSSQL database with many tables and relations. I want to bind it to my C# GUI application with text- and combo-boxes. Which one is the best way to do it: (1) Everything done manually by own classes and methods: Import data to dataset or to many datatables separately, then create dictionaries to comboboxes, manually retrieve data to textboxes and create a sql statement if update action will be invoked, or, (2) Done automatically by VS: Connect my controls with BindingSource and BindingNavigator if needed. I know how to deal with the first one, but if the second way would be better, my question is — how to achieve it? I haven't dealt with automatically created databindings and I don't know how to tell to DataBinding property (Key|Value|Text) about relations and current row's ID. And what is the method to cancel/update changes in all GUI elements? I need a simple solution for this scenario. It's a quick-and-dirty academical project, which must only "work" and be as fast implemented as it can. Thanks

• Problem with persisting interface collection at design time in winforms, .net

  - by Jules

  The easiest way to explain this problem is to show you some code: Public Interface IAmAnnoyed End Interface Public Class IAmAnnoyedCollection Inherits ObjectModel.Collection(Of IAmAnnoyed) End Class Public Class Anger Implements IAmAnnoyed End Class Public Class MyButton Inherits Button Private _Annoyance As IAmAnnoyedCollection <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As IAmAnnoyedCollection Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New IAmAnnoyedCollection Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class And this is the code that the designer generates: Private Sub InitializeComponent() Dim Anger1 As Anger = New Anger Me.MyButton1 = New MyButton ' 'MyButton1 ' Me.MyButton1.Annoyance.Add(Anger1) // Should be: Me.MyButton1.Annoyance.Add(Me.MyButton1.InternalAnger) ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub I've added a comment to the above to show how the code should have been generated. Now, if I dispense with the interface and just have a collection of Anger, then it persists correctly. Any ideas?

• What disables "Run Project" in Expression Blend 3

  - by Hugh

  I am developing a Sketchflow (Silverlight) project in Expression Blend 3. It has been working fine up until today, now I cannot run the project. Specifically in the Project menu the "Run Project" option is now greyed out (all the other options are fine). F5 also doesn't have any effect. I've obviously messed up the code somewhere but I can't find any information on what could cause the "Run Project" option to be disabled. This would obviously help the troubleshooting. Does anybody know what controls this functionality? I can build the project no problem. And if I package the project (so it runs outside Expression) this also works fine. It is just launching it from Expression that doesn't work.

• How to use RadSpell within a Telerik MVC Grid editor popup?

  - by Brian David Berman

  Is it possible to use RadSpell within a Telerik MVC Grid editor popup? I have followed some of the examples online to use RadSpell with ASP.NET MVC (http://www.telerik.com/help/aspnet-ajax/mvc-using-spellchecker.html and http://www.telerik.com/help/aspnet-ajax/spell-client-side-api.html) and I am able to attach multiple text controls to check but the display gets messed up when using Telerik MVC Grid editor popups since it's already in a modal. Sometimes it will randomly pick another div on the page and treats it like it's the main window (it will gray out just a portion of the page and I'll see the RadSpell popup peeking through but it's unusable). It seems like it chooses different places in the DOM to inject the iframe/radwindow for RadSpell as well. Any ideas? I didn't include any code because my implementation is a mess and I'd prefer to start with something simpler, from scratch.

• jQuery ajax in DotNetNuke preserving user authentication

  - by Michael Bradley

  I want to use jQuery's ajax functionality in a DotNetNuke module I'm developing. I want the ajax call to be authenticated via DNN's membership functionality. I want the ajax response as json. How can I do this? I've looked at IWeb and IWebCF -- it's not clear to me from much Googleing and scanning the forums whether these modules would allow me to create a web service that would accept a simple post request and return json (seems like they want to do it the ASP.NET AJAX way with a generated proxy, I'd prefer to just use jQuery's AJAX call functionality). Seems you can't create a simple webmethod in a DNN module (since they are developed as User Controls (.ascx)). I could deploy an .asmx file with module, but that won't leverage DNN's authentication system. Ideas? I'm currently developing against DNN 4.9.5

• How can I make a Qt widget ignore style sheets set on parent widgets?

  - by Hisham Abboud

  When adding a QComboBox control in Qt Designer, I get a terrible looking, non-native control, see: http://curiouschap.com/wp-content/uploads/2010/05/stack_qcombobox_question.png [as a newbie, SO wouldn't let me insert the image] On digging further, it turns out that two of the parent controls, QParentWindow and QStackedWidget, have style sheets that QComboBox is inheriting. If I delete the custom styles, then I get a native QComboBox like the one on the left. How can I have QComboBox (and widgets generally) NOT inherit parent styles? Or, how can I create a style for, say, QParentWindow, and do it so that it's local only and does not cascade?

• Silverlight SOS (Son of Strike) documenation

  - by Kris Erickson

  Is there any microsoft or even non-official documentation for SOS for Silverlight. Other than a few web posts I have seen zero documentation for it on MSDN. Even official documentation for the CLR version of SOS seems hard to find, this ancient article mentions a sos.htm file that is included in the windows SDK but it doesn't appear to be there any more. Any pointers to debugging Silveright with SOS?

• Save data in bulk.

  - by Muhammad Kashif Nadeem

  I have a window having multiple tabs. Each tab having different grids. I want to save all changes on any tab on any grid in bulk. I mean I have one save button which will save all changes in any grid on any tab. I think DataTables will work fine here. Can you suggest me that it is good to use DataTables to ADD/Edit data and save data in bulk using these DataTables OR is there any better way to achieve this. My DAL is generated from LLBLGen Pro (ORM) but you are open to suggest me a solution. Thanks. Edit: I am using Telerik controls so I can get all data in DataTable like DataTable dtProducts = this.radGridView1.DataSource as DataTable;

• Semi-transparent PNG Image on transparent Form

  - by Marco Bruggmann

  Hello, I have a problem dealing with transparent images on transparent Forms. I have been trying and looking for a solution but nothing useful came up. The problem is: I have a Form, this Form has a Panel and the Panel has a PictureBox. Form and Panel are transparent. Now, if the image of the PictureBox has no semi-transparent it works. But if there is a gradient transparency then the "transparent color" is shown. I need the Panel and the PictureBox, so the PerPixelAlpha does not apply for this case. The Form will also have more Controls that should be visible and non transparent (just the PNG image should be transparent). The image below shows: [Left] When the Panel is not transparent. [Center] When the Panel is transparent. [Right] Desired effect (done with PerPixelAlpha). http://www.freeimagehosting.net/uploads/3937fe974d.jpg THX Marco

• C#, WinForms: Why aren't KeyDown events chaining up to Form? I have to add event handler to each chi

  - by blak3r

  As i understand it, when a button is pressed it should first invoke the Control which has focus' KeyDown Handler, then it call the KeyDown handler for any Parent controls, all the way up to the main form. The only thing that would stop the chain would be if somewhere along the chain one of the EventHandlers did: e.SuppressKeyPress = true; e.Handled = true; In my case, KeyDown events never get to the main form. I have Form - Panel - button for example. Panel doesn't offer a KeyDown Event, but it shouldn't stop it from reaching the main form right? Right now as a work around I set every single control to call an event handler I wrote. I'm basically trying to prevent Alt-F4 from closing the application and instead minimize it.

• Conditions on the DetailsView

  - by jpabluz

  What is the best way of implementing conditions (requiring fields based in other fields) in a DetailsView? I have this: protected override ICollection CreateFieldSet(object dataItem, bool useDataSource) { var country = new BoundField(); country.DataField = "Country"; country.ReadOnly = ViewState["DifferentAddress"] != null; } I set the ViewState["DifferentAddress"] later, but since the change happens after the controls are created I lost the current state and get the old state. Which is the desired way of doing this? I am in the right path - or should I use another class to do this?

• Configure OutputCache for ASCX from web.config's cache profiles

  - by zar

  Hello, To configure aspx pages' OutputCache from one place, there is a great tool which is the CacheProfile attribute in <%@ OutputCache % associated with a custom cache profile defined in the web.config : <caching> <outputCacheSettings> <outputCacheProfiles> <add name="myProfile" duration="300" /> </outputCacheProfiles> </outputCacheSettings> </caching> And the line : <%@ OutputCache CacheProfile="myProfile" VaryByParam="None" %> does the job. But how to do the same thing for ascx user controls ? CacheProfile isn't in <%@ OutputCache % :S Is there a workaround ? Thanks.

• Newbie Android question

  - by DanyW

  Hi folks, I have just started with Android with the usual Hello World project template in Eclipse. I modified the layout XML and removed the label that says "Hello World, !", and added a couple of other controls. However, these are not reflected in the app, within the emulator. When I run this app from Eclipse again it is still showing the Hello World label! I'm sure it's something terribly simple that I have completely missed. Can someone please point me in the right direction? Many thanks, Dany.

• Combine master-detail databinding

  - by clawson

  I have created data sources from my objects in my project, some of which have other objects as members. When I want to bind a some objects to a data grid I would like to display some of the values from the member objects in the data grid as well but the examples I have come across seem to use an entire other datagrid or controls to display these member object values. How can I combine these values into one data grid? (Preferably without creating a wrapping class) Can I achieve this with LINQ somehow? Your help is greatly appreciated. Thanks P.S. C# or VB examples will do.

• Nested flowlayout panel not wrapping

  - by SnOrfus

  I've got a FlowLayoutPanel with properties: Dock = Fill (in a usercontrol) FlowDirection = TopDown WrapContents = false I do it this way so that each item added to the panel gets added to the bottom. The items that I add to this panel are usercontrols which themselves have FlowLayoutPanels on them, however they have the standard behaviour (LeftToRight, WrapContents = true). The problem that I'm having is that the interior usercontrol's FlowLayoutPanel isn't resizing to fill the outer control, but when I set autosizing to true on these controls, then the panel won't wrap its contents - which is a known problem apparently. If it helps visualize what I'm trying to do, it looks like this: ______________________________ | __________________________ | Outer box = exterior flowlayout | |Text____________________| | (TopDown, NoWrap) | | # # # # # # # # # # # #| | | | # # # # | | Interior boxes = usercontrols with text and a | |________________________| | flowlayoutpanel on them | __________________________ | (LeftToRight, Wrap) | |Text____________________| | | | # # # # # # # # # # # #| | # = pictures | | # # | | | |________________________| | |____________________________|

• Simple MPEG Video Stream player, cross-platform, in java, via NetBeans + Swing?

  Hello all, Trying to build a very simple video player component in a JPanel (or something similar) to sit in a swing app, connect to an mpeg (or, really, anything VLC can output) video stream, and play it. Don't need any controls or anything -- just a live connection to the video stream. It has to be cross-platform -- at least Mac and Windows (linux would be a nice bonus, but not necessary). I'm developing in NetBeans, so any specifics regarding that would be extra-helpful. JMF? Xuggler? Help! Thanks.
