• Python grab class in class definition.

  - by epochwolf

  I don't even know how to explain this, so here is the code I'm trying. class Test: type = self.__name__ #self doesn't work, how do I get a reference to Test? class Test2(Test): pass #Test2.type should return "Test2" The reason I'm even trying this is I'm working on creating a base class for an orm I'm using. I want to avoid defining the table name for every model I have. Also knowing what the limits of python is will help me avoid wasting time trying impossible things.

• What is Mono Behaviour?

  - by Starkers

  I'm getting this message multiple times when I try to run my game: The referenced script on this Behaviour is missing For some reason, all my prefabs are missing a script that dictates something called their 'Mono Behaviour': What is the Mono Behaviour component, and what does it do? How can I fix this error? I can click the little target circle to bring up all my scripts, but that just gives me all of the scripts that I've written: So I don't really know how to replace my missing Mono Behaviour script... Maybe if I knew what it was I could have a clue how to fix it. I probably moved something. But how can I select the Mono Behaviour script (whatever it is) if the target just shows me my scripts? Update I've moved some assets in the project window, but not via the OS (Finder/Explorer) so why is this happening? Also I am told that Mono Behaviour is a script I've applied... Don't really get this...isn't the script component a reference to a script?

• What does MySqlDataAdapter.Fill return when the results are empty?

  - by Brian

  I have a 'worker' function that will be processing any and all sql queries in my program. I will need to execute queries that return result sets and ones that just execute stored procedures without any results. Is this possible with MySqlDataAdapter.Fill or do I need to use the MySqlCommand.ExecuteNonQuery() method? Here is my 'worker' function for reference: private DataSet RunQuery(string SQL) { MySqlConnection connection; MySqlCommand command; MySqlDataAdapter adapter; DataSet dataset = new DataSet(); lock(locker) { connection = new MySqlConnection(MyConString); command = new MySqlCommand(); command = connection.CreateCommand(); command.CommandText = SQL; adapter = new MySqlDataAdapter(); adapter.Fill(dataset); } return dataset; }

• Any particular reason why FaceBook's Subscribe Button isn't showing on my web page?

  - by Axonn

  I got this FaceBook profile for my upcoming website and I can't get the Subscribe button to show, NOT EVEN ON FaceBook's page! http://www.facebook.com/profile.php?id=100003492130845 Now, if you go here on FaceBook's page where we build the Subscribe button: http://developers.facebook.com/docs/reference/plugins/subscribe/ And add the above link, it will show nothing. I enabled subscribing and I also created myself a page, linked to the same profile: http://www.facebook.com/pages/Axonn-Says/372194956141393 But not even the page works ::- /. LATER EDIT: I temporarily added 2 other Subscribe buttons on my website to demonstrate that it works for example for Mark Zuck's page and to demonstrate that there are no JS conflicts. The 2 buttons appeared ok, but my button still didn't show up.

• NullReferenceException makes me want to shoot myself

  - by rockinthesixstring

  Ok, so once upon a time, my code worked. Since then I did some refactoring (basic stuff so I thought) but now I'm getting a null reference exception, and I can't bloody well figure out why. Here's where it starts. note, this is the logout method, but all of my ActivityLogs sections are throwing this error Function LogOut(ByVal go As String) As ActionResult ActivityLogService.AddActivity(AuthenticationHelper.RetrieveAuthUser.ID, _ IActivityLogService.LogType.UserLogout, _ HttpContext.Request.UserHostAddress) ActivityLogService.SubmitChanges() ''# more stuff happens after this End Function The service is pretty straight forward (notice the ERROR THROWN HERE) Public Sub AddActivity(ByVal userid As Integer, ByVal activity As Integer, ByVal ip As String) Implements IActivityLogService.AddActivity Dim _activity As ActivityLog = New ActivityLog With {.Activity = activity, .UserID = userid, .UserIP = ip.IPAddressToNumber, .ActivityDate = DateTime.UtcNow} ActivityLogRepository.Create(_activity) ''#ERROR THROWN HERE End Sub And the Interface that the Service uses looks like this Public Interface IActivityLogService Sub AddActivity(ByVal userid As Integer, ByVal activity As Integer, ByVal ip As String) Function GetUsersLastActivity(ByVal UserID As Integer) As ActivityLog Sub SubmitChanges() ''' <summary> ''' The type of activity done by the user ''' </summary> ''' <remarks>Each int refers to an activity.

• Can I create many tables according to the same entity?

  - by jacob

  What I want to do is that I want to make the many tables dinamically which are the same entity structures. And then I want to refer to the dinamically created tables according to the table name. What I understood from hibernate reference is that I can only create only one table and it should be matched exactly with entity. So I can't find any solution to my problem. If you know any relevent open source related to my problem or any tip or web site, let me know. Thanks allways

• Windows Identity Foundation - Local STS on Windows Azure.

  - by joe

  Hello, I am trying to use Federated authentication on Azure. I found a example of having a local sts outside azure which is used for authentication from a web role hosted in azure. This works perfectly. My issue is, i dont want to have an application outside azure. Instead, I want to host the local sts website also in azure. So in effect I will have two web roles (1. my actual website, 2. the sts). I tried the above approach my creating a new webrole and moving the files from my original sts project. But i am getting compilation errors even if I reference the required dlls. I have also set "copy local" to true. It will be very helpful if somebody can guide me.. Thanks

• iOS: How to access the `UIKeyboard`?

  - by MattDiPasquale

  I want to get a pointer reference to UIKeyboard *keyboard to the keyboard on screen so that I can add a transparent subview to it, covering it completely, to achieve the effect of disabling the UIKeyboard without hiding it. In doing this, can I assume that there's only one UIKeyboard on the screen at a time? I.e., is it a singleton? Where's the method [UIKeyboard sharedInstance]. Brownie points if you implement that method via a category. Or, even more brownie points if you convince me why it's a bad idea to assume only one keyboard and give me a better solution.

• Where can I find boost::fusion articles, examples, guides, tutorials?

  - by Kyle

  I am going to go ahead and shamelessly duplicate this question because the accepted answer is essentially "nope, no guides" and it's been nearly a year now since it's been asked. Does anyone know of any useful articles, guides, tutorials, etc. for boost::fusion besides the barebones documentation on boost.org? (which I'm sure is great as a reference after one has learned the library.) I'm completely open to, say, a link to a book on Amazon. Searched for it myself just now but all I came up with was green tea. The top links on Google aren't much better.

• How to filter entities by their parents in ManyToOne side in Google App Engine

  - by palto

  I use Google App Engine. When I try to do a JPA query like this: "SELECT p FROM Participant p WHERE p.party.id = :partyKey AND p.name=:participantName" I get the following error Caused by: org.datanucleus.store.appengine.FatalNucleusUserException: SELECT FROM Participant p WHERE p.party.id = :partyKey AND p.name=:participantName: Can only reference properties of a sub-object if the sub-object is embedded. I gave the key of the Party object as a parameter to the "partyKey" named parameter. The model is like this: Party has multiple Participants. I want to query a participant based on the party and the name of the participant. I just can't figure out how to filter using the party. What options do I have?

• How do I access a DIV from javascript when using a master page?

  - by Rising Star

  I have a web page that contains a "div" element. On the page, there is javascript to reference the div: document.getElementById('divId'). This was working fine until another developer redesigned the page to use an ASP master page. Now, document.getElementById('divId') returns null. It appears that ASP.net prepends some characters to the names of elements within contents forms when you use a master page. How can I know what the id of the div is when the page loads? Update Allow me to give a specific example to clarify the question: My page had a div with ID divNotice. After changing my page to use a master page, I see when I print the source to the page that renders that the div ID is ctl00_ContentPlaceHolder1_divNotice. My question is, how am I supposed to know what the div ID is going to be when the framework is done with it?

• Can a Client Link to My JavaScript, Hosted on a Different Domain?

  - by DaveDev

  Is it possible for me to supply a client with a snippet of HTML which contains a reference to a javascript file that I host? They want to paste this HTML into their CMS, so that when their page loads, it'll load our content. I was under the impression that there was cross domain security preventing this from being possible. What if, instead of linking to the JavaScript, I gave them the snippet of HTML with the JavaScript already included so instead of <div> <!-- link to js --> </div> I gave them <div> $.get(/*url to my content*/); </div> Would that work?

• An Inaccessible JavaScript Object property - Why is Firebug showing this?

  - by Matty

  So, I'm attempting to access the content of an object and for the life of me can't figure out why I can't. I'm starting to believe that the object doesn't have the properties that Firebug indicates that it does. More likely than that I'm just not using the right syntax to access them. Give the following function: function(userData) { console.log(userData); // statement 1 console.log(userData.t_nodecontent); // statement 2 } Which generates the following FireBug output for statement 1 and unknown for statement 2. Is there something obvious that I'm overlooking in the way I'm attempting to reference the value of t_nodecontent? I'm at a loss :(

• download mail attachment with Java

  - by Don

  Hi, I had a look in the reference doc, and Spring seems to have pretty good support for sending mail. However, I need to login to a mail account, read the messages, and download any attachments. Is downloading mail attachments supported by the Spring mail API? I know you can do this with the Java Mail API, but in the past I've found that very verbose and unpleasant to work with. EDIT: I've received several replies pointing towards tutorials that describe how to send mail with attachments, but what I'm asking about is how to read attachments from received mail. Cheers, Don

• .NET TreeView causes application to crash when trying to check Parent node

  - by alexD

  I have a TreeView with check boxes, and when a user checks a child node, I want to go up the tree and check each parent. However, for some reason my application blows up whenever I touch the parent node. For the nodes in my tree, I've extended TreeNode to create my own objects with some data that I need to store in them, but I still reference them as TreeNodes when checking/unchecking. My code looks like this: //checkBox checked event handler if (node.Parent != null) { checkAllParents(node.Parent); } // private void checkAllParents(TreeNode node) { node.Checked = true; if (node.Parent != null) { checkAllParents(node.Parent); } }

• Sharepoint 2007 and <!DOCTYPE html>

  - by Kondor

  Greetings... I'm trying to get my Sharepoint 2007 site to render in Standards mode when browsing in IE. Since makes every browser that I might be worrying about do just that, I decided to use it. I've read here and there that Standards mode could cause unwanted behavior to some OOTB functionality and style (fly-outs, calendar items, etc...), but can't find a full list containing error reference and ways to correct it. So, I'm looking for any kind of info and guidance on the matter... Just trying to avoid endless clicking through my app and hopping that some one altruistic by nature has gone through testing hell already and is willing to share. Thanks...

• Disable IPV6 on specific NIC via PowerShell using a Com Object on Windows Server 2008 R2?

  - by user1256194

  I need to script some Windows Server 2008 R2 builds, preferably in PowerShell. I need to disable or uncheck IPV6 on a specific NIC (the same NIC every time). Currently, I have to set it manually. I do not want to disable IPV6 completely for the entire server other things may use that in the future. Is there an object I can reference in a PowerShell command specifying my NIC "Intel(R) PRO/1000 MT Network Connection" and disable IPV6? Unfortunately, Group Policy is not an option says the boss. I've tried finding an appropriate WMI object via "PowerShell Scriptomatic" but failed to find the difference between an enabled setting versus disabled on the Intel NIC. Thanks in advance.

• iPhone - Image overlay MapKit framework?

  - by Peter

  I can see with iOS4 you can now tile an image on google maps (Been looking at the TileMap example from apple). This is great as this is what I want to do, but from what I can see I need to know the GEO reference of the image so I can raster the images with the appropriate zoom levels, etc. What I have is an artist image, which is a map of a specific area and I want to overlay this image on google maps. Am I missing something here, but can this be done with a none standard map and having different zoom levels? The main reason why I need to use google maps is because of the GPS functionality, so the user will know where they currently are on the map.

• PHP DOMElement, replacing text of a node

  I have a HTML node like so: <b>Bold text</b> A variable $el contains a DOMElement reference to the text of that HTML node ("Bold text"), got from the XPath expression //b/text() I want to change the element to <b><span>Bold Text</span></b> So I tried: $span = $doc->createElement('span', "Bold Text"); $el->parentNode->replaceChild($span,, $el) which fails because parentNode is null. So, as a test, I tried: $el-insertBefore($span, $el); which throws no errors but produces no change in the output. Any thoughts?

• How to get at ResourceDictionary style when it is loaded from external xap and assemblies are MEF-fe

  - by user158503

  I've got the following setup: The main application loads a XAP with an IPlugin implementation. The Plugin contains a 'DisplayPanel' that contains a referenced Control with other controls. The DisplayPanel here is simply a container control to show referenced Control. This referenced Control, from an assembly, uses a Style from a ResourceDictionary xaml in this assembly. At least that's what I want to have. The problem is that the referenced Control throws an error: Cannot find a Resource with the Name/Key PlayerPanelGrad [Line: 1500 Position: 127] I've tried to get at the style by referencing the ResourceDictionary through a Merged Resource dictionary reference: <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="TableControls;component/ControlsStyle.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> But that doesn't work. How would you approch this?
