  • Can I destroy a class instance even if there are still references?

    - by DR
    For debugging reasons I want to destroy a class instance which still as references. Is that possible? It doesn't have to be elegant or stable, because this'll never end up in production code. To clarify: Public Sub Main Dim o as MyClass Set o = New MyClass //o is created, one reference DestroyObject o //Class_Terminate is called and the object destroyed //Further code, not using o End Sub //Possible runtime error here (don't care) Is that possible? One way would be to call IUnknown::Release to manually decrease the reference count, but how do I now how often I must call it?

  • How to retrieve XML attribute for custom control

    - by David
    I've created a combo box control with a edittext and spinner. I'm trying to let the android:prompt attribute be passed onto the spinner, which means I need to catch it in the constructor which passes my the AttributeSet and set it on the spinner. I can't figure out how to get the value of the prompt. I'm trying, int[] ra = { android.R.attr.prompt }; TypedArray ta = context.getTheme().obtainStyledAttributes(ra); int id = ta.getResourceId(0, 0); I get back 0, which means it didn't find the attribute. I also did a ta.count() which returned 0. So I'm not getting anything back. My XML simply defines an android:prompt value. Thanks

  • Unittest and mock

    - by user1410756
    I'm testing with unittest in python and it's ok. Now, I have introduced mock and I need to resolve a question. This is my code: from mock import Mock import unittest class Matematica(object): def __init__(self, op1, op2): self.op1 = op1 self.op2 = op2 def adder(self): return self.op1 + self.op2 def subs(self): return abs(self.op1 - self.op2) def molt(self): return self.op1 * self.op2 def divid(self): return self.op1 / self.op2 class TestMatematica(unittest.TestCase): """Test della classe Matematica""" def testing(self): """Somma""" mat = Matematica(10,20) self.assertEqual(mat.adder(),30) """Sottrazione""" self.assertEqual(mat.subs(),10) class test_mock(object): def __init__(self, matematica): self.matematica = matematica def execute(self): self.matematica.adder() self.matematica.adder() self.matematica.subs() if __name__ == "__main__": result = unittest.TextTestRunner(verbosity=2).run(TestMatematica('testing')) a = Matematica(10,20) b = test_mock(a) b.execute() mock_foo = Mock(b.execute)#return_value = 'rafa') mock_foo() print mock_foo.called print mock_foo.call_count print mock_foo.method_calls This code is functionally and result of print is: True, 1, [] . Now, I need to count how many times are called self.matematica.adder() and self.matematica.subs() . THANKS

  • What is the maximum number of controls that a VBA form can hold?

    - by Lunatik
    I'm currently building an Excel 2003 app that requires a horribly complex form and am worried about limitations on the number of controls. It currently has 154 controls (counted using Me.Controls.Count - this should be accurate, right?) but is probably only about a third complete. The workflow really fits a single form, but I guess I can split it up if I really have to. I see evidence in a Google search that VB6 (this usually includes VBA) has a hard limit of 254 controls in a form. However, I created a dummy form with well over 1200 controls which still loaded and appeared to work just fine. I did get some 'out of memory' errors when trying to add specific combinations of controls though, say 800 buttons and 150 labels, leading me to think that any limit might be affected by the memory requirements of each type of control. Does anyone have any information that might help ensure that I or, more importantly, other users with differing environments don't run into any memory issues with such a large form?

  • HTML: Display:none does this allow multiple ID-Attributes with same name (when "hidden")?

    - by Jan
    Hello, according to the HTML Standards ID-Attributes of any HTML Tag in a webpage have to be unique in the document!? Does this rule also apply to HTML Tags that have been "disabled/hidden" by using: display:none? Example: <html> <body> <div id="one"></div> <div id="one" style="display:none;"></div> </body> </hmtl> Is this valid HTML or not. So the question is do "display:none"= hidden Elements also "count/matter" in regard to the rule only having unique ID-Attributes in a single webpage? Thanks Jan

  • SQLite Transaction fills a table BEFORE the transaction is commited

    - by user1500403
    Halo I have a code that creates a datatable (in memory) from a select SQL statement.

Inalready.Clear() 'clears a dictionary Using connection As New SQLite.SQLiteConnection(conectionString) connection.Open() Dim sqliteTran As SQLite.SQLiteTransaction = connection.BeginTransaction() Try oMainQueryR = "SELECT * FROM detailstable Where name= :name AND Breed= :Breed" Dim cmdSQLite As SQLite.SQLiteCommand = connection.CreateCommand() Dim oAdapter As New SQLite.SQLiteDataAdapter(cmdSQLite) With cmdSQLite .CommandType = CommandType.Text .CommandText = oMainQueryR .Parameters.Add(":name", SqlDbType.VarChar) .Parameters.Add(":Breed", SqlDbType.VarChar) End With Dim c As Long = 0 For Each row As DataRow In list.Rows 'this is the list with 500 names If Inalready.ContainsKey(row.Item("name")) Then Else c = c + 1 Form1.TextBox1.Text = " Fill ....

  • django + xmppy: send a message to two recipients

    - by Agrajag
    I'm trying to use xmpppy for sending jabber-messages from a django-website. This works entirely fine. However, the message only gets sent to the -first- of the recipients in the list. This happens when I run the following function from django, and also if I run it from an interactive python-shell. The weird part though, is that if I extract the -body- of the function and run that interactively, then all the recipients (there's just 2 at the moment) get the message. Also, I do know that the inner for-loop gets run the correct count times (2), because the print-statement does run twice, and return two different message-ids. The function looks like this: def hello_jabber(request, text): jid=xmpp.protocol.JID(settings.JABBER_ID) cl=xmpp.Client(jid.getDomain(),debug=[]) con=cl.connect() auth=cl.auth(jid.getNode(),settings.JABBER_PW,resource=jid.getResource()) for friend in settings.JABBER_FRIENDS: id=cl.send(xmpp.protocol.Message(friend,friend + ' is awesome:' + text)) print 'sent message with id ' + str(id) cl.disconnect() return render_to_response('jabber/sent.htm', locals())

  • Asp.net mvc 2 and twitter authenticaton

    - by arinte
    I am using OAuth (linq2twitter and DotNetOpenAuth) to allow a user to post comments via their twitter account. So when you do the authorization twitter does a callback, so the way linq2twitter does it is to set the callback to the page that did the req. So if the req came from blah.com\twit it will redirect to blah.com\twit. This leads me to have code like this: public ActionResult Twit(){ var qString = Request.QueryString; if (qString.Count <= 0){ //do authorization } else{ //do authentication } } So I would like to split it to this(seemingly both of these calls are done via GET): public ActionResult Twit(){} public ActionResult Twit(string token1, string token2){} When I have this currently I get the .net yellow screen complaining about ambiguous action methods. How do I route this?

  • CSS3 Continous Rotate Animation (Just like a loading sundial)

    - by Gcoop
    Hi, I am trying to replicate an Apple style activity indicator (sundial loading icon) by using a PNG and CSS3 animation. I have the image rotating and doing it continuously, but there seems to be a delay after the animation has finished before it does the next rotation. @-webkit-keyframes rotate { from { -webkit-transform: rotate(0deg); } to { -webkit-transform: rotate(360deg); } } #loading img { -webkit-animation-name: rotate; -webkit-animation-duration: 0.5s; -webkit-animation-iteration-count: infinite; -webkit-transition-timing-function: linear; } I have tried changing the animation duration but it makes no difference, if you slow it right down say 5s its just more apparent that after the first rotation there is a pause before it rotates again. It's this pause I want to get rid of. Any help is much appreciated, thanks.

  • how have defined connection within function for pdo communication with DB

    - by Scarface
    hey guys I just started trying to convert my query structure to PDO and I have come across a weird problem. When I call a pdo query connection within a function and the connection is included outside the function, the connection becomes undefined. Anyone know what I am doing wrong here? I was just playing with it, my example is below. include("includes/connection.php"); function query(){ $user='user'; $id='100'; $sql = 'SELECT * FROM users'; $stmt = $conn->prepare($sql); $result=$stmt->execute(array($user, $id)); echo $count=$stmt->rowCount(); if (!$result || $stmt->rowCount()>=1){ echo 'balls'; } // now iterate over the result as if we obtained // the $stmt in a call to PDO::query() while($r = $stmt->fetch(PDO::FETCH_ASSOC)) { echo "$r[username] $r[id] \n"; } } query();

  • Intellisense in Visual Studio 2010

    - by Erik
    For some reason the Intellisense in vb.net stopped working when I use an Aggregate Lambda expression inside a With statement. With Me.SalesPackage .WebLinks = Sales.Where(Function(f) f.Current.BookerWeb > 0).Count .WebAmount = Aggregate o In Sales.Where(Function(f) f.Current.WebBooker > 0) Into Sum(o.Current.WebPrice) End With If I insert a new line between .WebLinks and .WebAmount and start typing, it works. But it won't work if I do it after the Aggregate statement... Any ideas?

  • How do I reset a countdown timer when it reaches 0? (Xcode 4)

    - by Zac Prunty
    first question and I have researched the heck out of this and can't seem to find any answers. I would like to implement a countdown timer in my app that starts at 30 seconds and resets when it hits 0. It will count back by 1 second intervals. I have played around with the resources that Apple provides and I can't seem to implement the NStimer to do as I just explained. Are there any suggestions on how I could code this? I would eventually like to link this to a button that will start the timer when it is pressed. I appreciate any advice on this topic!

  • How to prune data set by frequency to conform to paper's description

    - by sakura90
    The MovieLens data set provides a table with columns: userid | movieid | tag | timestamp I have trouble reproducing the way they pruned the MovieLens data set used in: Tag Informed Collaborative Filtering, by Zhen, Li and Young In 4.1 Data Set of the above paper, it writes "For the tagging information, we only keep those tags which are added on at least 3 distinct movies. As for the users, we only keep those users who used at least 3 distinct tags in their tagging history. For movies, we only keep those movies that are annotated by at least 3 distinct tags." I tried to query the database: select TMP.userid, count(*) as tagnum from (select distinct T.userid as userid, T.tag as tag from tags T) AS TMP group by TMP.userid having tagnum >= 3; I got a list of 1760 users who labeled 3 distinct tags. However, some of the tags are not added on at least 3 distinct movies. Any help is appreciated.

  • What good timesheet should and shouldn't have for a small (non programming) 50 people company?

    - by MadBoy
    I'm sure most people here had to fill at least one time sheet in their life that made their life miserable, hell it's even the worst time taker ever especially after you have to fill it in hurry. I will be developing some simple TimeSheet application for a small company of 50 people (non programming related, it's actually 4 companies working together) and would like it to be user friendly and as less disturbing as possible. So what in your opinion makes it a good timesheet (lack of it doesn't count :p), what data it should store? Should be only hours per day with possibility to choose project, company and simple overview what you have worked on like: Day 1, 3:00, 'Company 1', 'Project5', 'Name', Short Overview Day 1, 5:00, 'Company 2', 'Project6', 'Name', Short Overview Or should it gather more data? Would it be realy bad if it were an WinForms application considering that I don't know ASP.NET or any other web based language? I would be deploying it using ClickOnce or so.

Here's what i'm trying, but i get no output: #!/bin/bash deleted=`mysql mydb -e "delete from mytable where insertedtime < '2010-04-01 00:00:00'"|tail -n 1` I was expecting something like this as the output from mysql: deleted 999999 Which is why i have the tail -n 1 so i only pick up the count and not the column name. Any help would be most appreciated.
