• Handling button presses in Gtk2::Image objects

  - by willert

  I've been trying to get an Gtk2::Image object in this perl Gtk2 application to get to react to button presses, but to no avail. The image shows as expected but the button events don't get handled. What am I missing? my $img = Gtk2::Image-new_from_file( $file ); $img-set_property( sensitive = 1 ); $img-can_focus( 1 ); $img-set_events([qw/ button-press-mask button-release-mask /]); $img-signal_connect( 'button-press-event' = sub { my ( $self, $event ) = @_; print STDERR "Coords: ", $event-get_coords; return; }); $window-add( $img ); $window-show_all;

• ruby, rails, railscasts example gone bad

  - by Sam

  If you saw the railscasts on nested forms this is the helper method to create links dynamically. However, after I upgraded to ruby 1.9.2 and rails 3 this doesn't work and I have now idea why. def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end here is the javascript function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); }

• ASP.NET Nested Repeater Accessing elements

  - by Rich

  I have a list of Accommodation objects bound to a Repeater, and then a nested Repeater which has the various attendee groups listed [e.g. Default, Seniors, Juniors]. This is all output fine, with the values displayed as LinkButtons, which when clicked gets sent to a code-behind event handler. Here is an example of the output to give you a picture [with some er... interesting attendee group names]: In the event handler, I test the object parameter to see which Repeater has been sent, as the outer repeater's links can also be clicked [so the Accommodation would be set, but no Attendee Group]. Is there a way to get a HiddenField from the outer RepeaterItem that contains the currently clicked inner repeater's LinkButton? E.g. From the image, I click the Attending link in the Women section. So the EventArgs via FindControl can get me the hidden field which contains the Attendee Group's ID, which is good, but I also need the Accommodation ID [to know whether it was either Wimbledon Hotel Inn or New Acc]

• Nothing = String.Empty (Why are these equal?)

  - by Ek0nomik

  I find it very puzzling that null equals String.Empty in VB.NET. There must be an explanation for it that I'm not understanding. Somehow, when the equality of String.Empty (which has an object type of string) is tested against Nothing (which has no type) the test returns true. It just seems like a turn around in logic to me. In SQL if I were to compare an empty char or varchar against a null value, the test wouldn't return true. A null value is not the same as an empty string in this case. Yet in VB.NET they are equal. I'd love it if someone could provide a good explanation around this.

• R: How to tell lapply to ignore an error and process the next thing in the list?

  - by John

  I have an example function below that reads in a date as a string and returns it as a date object. If it reads a string that it cannot convert to a date, it returns an error. testFunction <- function (date_in) { return(as.Date(date_in)) } testFunction("2010-04-06") # this works fine testFunction("foo") # this returns an error Now, I want to use lapply and apply this function over a list of dates: dates1 = c("2010-04-06", "2010-04-07", "2010-04-08") lapply(dates1, testFunction) # this works fine But if I want to apply the function over a list when one string in the middle of two good dates returns an error, what is the best way to deal with this? dates2 = c("2010-04-06", "foo", "2010-04-08") lapply(dates2, testFunction) I presume that I want a try catch in there, but is there a way to catch the error for the "foo" string whilst asking lapply to continue and read the third date?

• Django : proper way to use model, duplicates!

  - by llazzaro

  Hello, I have a question about the proper, best way to manage the model. I am relative newbie to django, so I think I need to read more docs, tutorials,etc (suggestions for this would be cool!). Anyway, this is my question : I have a python web crawler, that is "connected" with django model. Crawling is done once a day, so its really common to find "duplicates". To avoid duplicates I do this : cars = Car.Objects.filter(name=crawledItem['name']) if len(cars) 0: #object already exists, update it car = cars[0] else: car = Car() #some non-relevant code here car.save() I want to know, if this is the proper/correct way to do it or its any "automatic" way to do it. Its possible to put the logic inside the Car() constructor also, should I do that? Thanks a lot!

• Is there any way, short of "copy and paste inheritence" to share a .net class with a Silverlight app

  - by Jekke

  I have a project in two parts: a Silverlight front end and a WCF duplex service. Ideally, I would like to pass a message of a custom type (call it TradeOffer) from the WCF service to be consumed by the Silverlight application. When I try to, I get an error that indicates I can't pass an object of an unknown type across the wire like that and that, maybe, I could do so if I used the InternalsVisibleTo attribute on the server component. I'm not sure if that would work in this environment and know it would be messy in development. I originally put the message definition in a library to be used by both the service and the client, but couldn't add a reference to the library from the Silverlight client (because it's not a Silverlight assembly.) Is there some way I can access the definition of a message class from both the Silverlight client that consumes it and the service that publishes it without using the InternalsVisibleTo attribute or should I write the application another way?

• HTTP MODULE Event Does Not Fire When Click Browser's Back Button

  - by Ali

  I Wrote an Http Module that checks if logged user is restricted disables images on the page. void application_AuthorizeRequest(object sender, EventArgs e) { . . . if (context.User.IsInRole("Restricted")) { context.Response.StatusCode = 401; context.Response.End(); } The code works fine. When the page loads, every image on the screen disapears. but when I go to another page and click back button on the browser and goto previous page images appear. What should I? (I dont want to clear Cache every time) context.Response.Cache.SetNoStore(); context.Response.Cache.SetCacheability(HttpCacheability.NoCache);

• constructors and inheritance in JS

  - by nandinga

  Hi all, This is about "inheritance" in JavaScript. Supose I create a constructor Bird(), and another called Parrot() which I make to "inherit" the props of Bird by asigning an instance of it to Parrot's prototype, like the following code shows: function Bird() { this.fly = function(){}; } function Parrot() { this.talk = function(){ alert("praa!!"); }; } Parrot.prototype = new Bird(); var p = new Parrot(); p.talk(); // Alerts "praa!!" alert(p.constructor); // Alerts the Bird function!?!?! After I've created an instance of Parrot, how comes that the .constructor property of it is Bird(), and not Parrot(), which is the constructor I've used to create the object? Thanks!!

• Avoiding exceptions when uploading files in laravel

  - by occam98

  I've got a file upload field (attachment1) in a form that may or may not have a file uploaded in it when I process the form in laravel. When I'm trying to process the page, this line generates an exception: Input::upload('attachment1',path('storage').'attachments/'.$name); Here is the text of the exception: Message: Call to a member function move() on a non-object it seems that I need to check in advance to see if 'attachment1' has a file, and I found that the function Input::has_file('attachment1') is supposed to tell me whether or not 'attachment1' has a file, but even when I submit an empty form, it returns true. Also, from reading documentation, it seems that Input::upload is supposed to just return false when trying to upload a non-existant file, so why does it produce this exception instead, and how can I fix it?

• Android MediaPlayer crashing app

  - by user1555863

  I have an android app with a button that plays a sound. the code for playing the sound: if (mp != null) { mp.release(); } mp = MediaPlayer.create(this, R.raw.match); mp.start(); mp is a field in the activity: public class Game extends Activity implements OnClickListener { /** Called when the activity is first created. */ //variables: MediaPlayer mp; //... The app runs ok, but after clicking the button about 200 times on the emulator, app crashed and gave me this error https://dl.dropbox.com/u/5488790/error.txt (couldn't figure how to post it here so it will appear decently) i am assuming this is because the MediaPlayer object is consuming up too much memory, but isn't mp.release() supposed to take care of this? What am i doing wrong here?

• Enable intellisense for imported tlb in VC++ 6

  - by Kevin Day

  We have a library for a complex COM object that we are importing using the following: #import "library.tlb" this works fine, VC++ compiles a tli file and somehow that gets magically included in the build process, so code written against the tlb works. However, intellisense doesn't pick up the library entries. This is a crazy complex COM component, and having intellisense would help immensely. Can anyone provide some pointers on how to get intellisense to work properly with this? I have tried deleting the .ncb file, and that had no effect.

• Jabber .net rostertree error

  - by Farooq

  Hi, Whenever I add the rostertree control to my form, I can see that the PresenceManager and RosterManager property values for it have this error listed: "Unable to cast object of type 'System.Windows.Forms.DataGridViewTextBoxColumn' to type 'System.ComponentModel.Component'." I can compile the solution and all but this error keeps popping up randomly. Can someone advice when this may happen. I'm thinking it has to do with the controls not being added properly. I'm using Visual Studio 2008. Thanks.

• Fluent-NHibernate - Component property attributes ignored by Convention

  - by BobTodd

  I have a component with a number of properties that have various attributes Normally when these attributes are added to a plain old domain object they are picked up by my custom AttributeConventions. For the Component properties they are not. Is there some extra wiring needed for these? e.g. public class Component { [Length(Max=50)] public virtual string Name {get; set;} } public class MyClass { public virtual Component Component {get; set;} [Length(Max=50)] public virtual string Color {get; set;} } I get a table MyClass with columns Color & ComponentName Color is an nvarchar(50) whilst ComponentName is an nvarchar(255) (the default)

• Difference between "traditional" COM and COM+ (in Component Services)

  - by kizzx2

  By the "traditional" way I mean registering the DLL in registry. There seems to be another method to set up it by going to mmc-Component Services-COM+ Applications and adding the .tlb file. I have a COM library that supports both methods. When it installs, it registers itself in the registry as a COM component and it works fine. However, when I added the .tlb file using the Component Services method, the behavior seems to be different and it starts giving out errors. I suspect it has something to do with marshaling and inter-process object transfer? (Sorry, I'm really a noob in the COM area) Can anyone point me to a good resource to clear my understanding?

• Access 2003 - Embedded ppt slide or Excel Spreadsheet in a form, how do I communicate?

  - by Justin

  So if I was to take a an access form, and embed either an excel spreadsheet into it, or a powerpoint slide/pres, how would I reference it in VBA code? So I know I have to set the libraries, name the frame of the OLE object, and use applicable syntax to whatever I want to do, with whatever I stick in the form, however the only things I have ever done with excel and/or powerpoint is automate the opening of a seperate window/application from access, not within the access form....so I am not sure?? if I said its a new Excel.Application, then set xls = to (the ss in the file, and not some file path of another excel file somewhere)? does that make sense?

• Finding parents where child collection does not contain an item with a specific property value

  - by Colin Bowern

  I am trying to get a list of parents where the child collection does not contain an item of a specific type. The LINQ equivalent would be something like: dataset.Where(x => x.Items.FirstOrDefault(y => y.Type.Code == "ABC") == null) The object model is Parent Child (Items) Type Code If Parent is my aggregate root, how would I model this in NHibernate criteria/query? Here's my first attempt: var results = session.CreateCriteria<Parent>() .CreateCriteria("Items") .CreateCriteria("Type") .Add(Restrictions.Not(Restrictions.Eq("Code", "ABC"))) .SetResultTransformer(Transformers.DistinctRootEntity) .List<Parent>(); This doesn't seem to return the right entities - it just returns them all.

• Casting Error with Reflection

  - by Mitchel Sellers

  I have an application that uses plugins that are managed via an interface I then dynamically load the plugin classes and cast them to the interface to work with them. I have the following line of code, assume that IPlugin is my interface. IPlugin _plugin = (IPlugin)Activator.CreateInstance(oInfo.Assembly, oInfo.FullyQualifiedName) This should be pretty simple, create the instance and cast it to the interface. I know that the assembly and fully qualified name values are correct, but I am getting the following exception. Exception= System.InvalidCastException: Unable to cast object of type ‘System.Runtime.Remoting.ObjectHandle’ to type ‘MyNamespace.Components.Integration.IPlugin’. at MyNamespace.Components.Integration.PluginProxy..ctor(Int32 instanceId) Any ideas what could cause this?

• How to make Databinding type safe and support refactoring

  - by Ian Ringrose

  When I wish to bind a control to a property of my object, I have to provide the name of the property as a string. This is not very good because: If the property is removed or renamed, I don’t get a compiler warning. If a rename the property with a refactoring tool, it is likely the data binding will not be updated. I don’t get an error until runtime if the type of the property is wrong, e.g. binding an integer to a date chooser. Is there a design-paten that gets round this, but still has the ease of use of data-binding? (This is a problem in WinForm, Asp.net and WPF and most likely lots of other systems) I have now found "workarounds for nameof() operator in C#: typesafe databinding" that also has a good starting point for a solution.

• Can't parse a 1904 date in ARPA format (email date)

  - by Ramon

  I'm processing an IMAP mailbox and running into trouble parsing the dates using the mxDateTime package. In particular, early dates like "Fri, 1 Jan 1904 00:43:25 -0400" is causing trouble: >>> import mx.DateTime >>> import mx.DateTime.ARPA >>> mx.DateTime.ARPA.ParseDateTimeUTC("Fri, 1 Jan 1904 00:43:25 -0400").gmtoffset() Traceback (most recent call last): File "<interactive input>", line 1, in <module> Error: cannot convert value to a time value >>> mx.DateTime.ARPA.ParseDateTimeUTC("Thu, 1 Jan 2009 00:43:25 -0400").gmtoffset() <mx.DateTime.DateTimeDelta object for '-08:00:00.00' at 1497b60> >>> Note that an almost identical date from 2009 works fine. I can't find any description of date limitations in mxDateTime itself. Any ideas why this might be? Thx, Ramon

• Automating Visual Studio 2010 from a console app

  - by JoelFan

  I am trying to run the following code (which I got from here). The code just creates a new "Output" pane in Visual Studio and writes a few lines to it. Public Sub WriteToMyNewPane() Dim win As Window = _ DTE.Windows.Item(EnvDTE.Constants.vsWindowKindOutput) Dim ow As OutputWindow = win.Object Dim owPane As OutputWindowPane Dim cnt As Integer = ow.OutputWindowPanes.Count owPane = ow.OutputWindowPanes.Add("My New Output Pane") owPane.Activate() owPane.OutputString("My text1" & vbCrLf) owPane.OutputString("My text2" & vbCrLf) owPane.OutputString("My text3" & vbCrLf) End Sub Instead of running it as a Macro, I want to run it as an independent console application that connects to a currently running instance of Visual Studio 2010. I'm having a hard time figuring out how to set the value of DTE. I think I may need to call GetActiveObject, but I'm not sure how. Any pointers?

• Which cross threading invoke function is better for a control that is inherited?

  - by Stevoni

  I have a relatively simple question regarding the best way to call the DataGridView.Rows.Add function when it is inherited into the current control. Which is the best way to make the call to the inherited control? Call it directly in the invoke or call it using recursive-like function? They both seem to produce the same result, a row gets added and the quantity is returned, but which is the most efficient? The delegate: Private Delegate Function ReturnDelegate() As Object The two ways are: A) Private Overloads Function AddRow() As Integer If InvokeRequired Then Return CInt(Invoke(New ReturnDelegate(AddressOf AddRow))) Else Return Rows.Add() End If End Function Or B) Private Function RowsAdd() As Integer If Me.InvokeRequired Then Return CInt(Me.Invoke(New ReturnDelegate(AddressOf MyBase.Rows.Add))) Else Return MyBase.Rows.Add End If End Function

• String to date (Invalid format)

  - by MrThys

  I am using Joda Time library to convert my String dates to a real date, because this seemed like the easiest solution to do this. I am using the DateTime object to do this; new DateTime(strValue); But when inserting some formats it throws me the exception; java.lang.IllegalArgumentException: Invalid format: "Mon, 30 Sep 2002 01:56:02 GMT" java.lang.IllegalArgumentException: Invalid format: "Sun, 29 Sep 2002 19:59:01 GMT" java.lang.IllegalArgumentException: Invalid format: "Mon, 30 Sep 2002 01:52:02 GMT" java.lang.IllegalArgumentException: Invalid format: "Sun, 29 Sep 2002 17:05:20 GMT" java.lang.IllegalArgumentException: Invalid format: "Sun, 29 Sep 2002 19:09:28 GMT" java.lang.IllegalArgumentException: Invalid format: "Sun, 29 Sep 2002 15:01:02 GMT" java.lang.IllegalArgumentException: Invalid format: "Sun, 29 Sep 2002 23:48:33 GMT" java.lang.IllegalArgumentException: Invalid format: "Sun, 29 Sep 2002 17:24:20 GMT" java.lang.IllegalArgumentException: Invalid format: "Sun, 29 Sep 2002 11:13:10 GMT" Is there a way to solve this, or should I use something else instead of DateTime.
