  • How to install pyobjc on SnowLeopard's non-default python installation

    - by IgorJ
    Hi everybody. I'm having problems installing pyobjc on SnowLeopard. It came with python 2.6 but I need 2.5 so I have installed 2.5 successfully. After that I have installed xcode. After that I have installed pyobjc with "easy_install-2.5 pyobjc" But when I start my python 2.5 and from cmd line try to import Foundation, it says "no module named Foundation" Of course, from 2.6 everything works fine. How do I find out what's wrong and what should i do?

  • Default Object being modified because of LINQ Query

    - by msarchet
    I'm doing the following code to filter a list of objects before it gets sent off to be printed. Dim printList As New List(Of dispillPatient) For Each pat As dispillPatient In patList If (From meds In pat.Medication Select meds Where meds.Print = True).Count > 0 Then Dim patAdd As New dispillPatient patAdd = pat patAdd.Medication = DirectCast((From meds In pat.Medication Select meds Where meds.Print = True).ToList, List(Of dispillMedication)) printList.Add(patAdd) End If Next What is happening is patList, which is my initial list, for every dispillPatient inside of it, that specific patients Medication object (which is another list), is being shorten to the list that is returned to the patAdd object. I think this has something to do with both the way that .NET makes the copy of my pat object when I do patAdd = pat and the LINQ query that I'm using. Has anyone had a similar issue before and\or what can I do to keep my initial list from getting truncated. Thanks

  • What language has the longest "Hello world" program?

    - by Kip
    In most scripting languages, a "Hello world!" application is very short: print "Hello world" In C++, it is a little more complicated, requiring at least 46 non-whitespace characters: #include <cstdio> int main() { puts("Hello world"); } Java, at 75 non-whitespace characters, is even more verbose: class A { public static void main(String[] args) { System.out.print("Hello world"); } } Are there any languages that require even more non-whitespace characters than Java? Which language requires the most? Notes: I'm asking about the length of the shortest possible "hello world" application in a given language. A newline after "Hello world" is not required. I'm not counting whitespace, but I know there is some language that uses only whitespace characters. If you use that one you can count the whitespace characters.

  • ASP C# Web Developer default login, getting user ID session value

    - by m3n
    I've used the built-in wizard in Visual Web Developer 2008 to create a simple login system. I'd like to get hold of the logged in user's ID, but I'm not sure how. Peeking in the ASPNETDB.MDF in the table aspnet_Users, the column appears to be called "UserId". I gave it a go: Response.Write("ID: " + Session["UserId"]); but it's coming up blank. How do I do this? (This is not for a live project, no need to point out the sillyness in using the wizard.) Thanks

  • Indentation (and wrap-indentation) of debug strings output by printf()/fprintf() in C program

    - by mbaitoff
    I'm using a debug output using printf() in my functions, but the output goes to the console starting at the 1st columns. I'd like to distinguish the nesting level of functions by indenting their output strings each time I dive into the function (it's implemented easily having a static int indentlevel; variable, which is incremented at the beginning of a function, used as a space-filler-count and decremented at the end). But the flaw is that once the output line becomes too long to be wrapped at the console edge, lines' wrapped parts start at column 1 of the console. Should I take care about this, since once the output is redirected to a file, lines are, say, one-line-length, and widths of the lines depend only on the text file viewer settings?

  • Default values for model fields in a Ruby on Rails form

    - by Callum Rogers
    I have a Model which has fields username, data, tags, date, votes. I have form using form_for that creates a new item and puts it into the database. However, as you can guess I want the votes field to equal 0 and the date field to equal the current date when it is placed into the database. How and where would I set/apply these values to the item? I can get it to work with hidden fields in the form but this comes with obvious issues (someone could set the votes field to a massive number.

  • Perl OO frameworks and program design - Moose and Conway's inside-out objects (Class::Std)

    - by Emmel
    This is more of a use-case type of question... but also generic enough to be more broadly applicable: In short, I'm working on a module that's more or less a command-line wrapper; OO naturally. Without going into too many details (unless someone wants them), there isn't a crazy amount of complexity to the system, but it did feel natural to have three or four objects in this framework. Finally, it's an open source thing I'll put out there, rather than a module with a few developers in the same firm working on it. First I implemented the OO using Class::Std, because Perl Best Practices (Conway, 2005) made a good argument for why to use inside-out objects. Full control over what attributes get accessed and so on, proper encapsulation, etc. Also his design is surprisingly simple and clever. I liked it, but then noticed that no one really uses this; in fact it seems Conway himself doesn't really recommend this anymore? So I moved to everyone's favorite, Moose. It's easy to use, although way way overkill feature-wise for what I want to do. The big, major downside is: it's got a slew of module dependencies that force users of my module to download them all. A minor downside is it's got way more functionality than I really need. What are recommendations? Inconvenience fellow developers by forcing them to use a possibly-obsolete module, or force every user of the module to download Moose and all its dependencies? Is there a third option for a proper Perl OO framework that's popular but neither of these two?

My function for calculating age: function AmziusFunc(Mas : TZmogus) : longint; var i, s : integer; amzius, max : longint; begin max := 125 * 365; amzius := (Mas.mirY - Mas.gimY) * 365 + (Mas.mirM - Mas.gimM) * 31 + (Mas.mirD - Mas.gimD); if ( amzius >= max ) then amzius := 0; AmziusFunc := amzius; end; What should i change there? Thanks.

  • Functional testing of a 3-rd party java program

    - by Dmitri Nesteruk
    I have a 3-rd party java application (I don't own source code) and I want to perform functional testing on it, similar to the way it's done in watin/watij/selenium/nunitforms etc. Can anyone suggest a library that I can use to do this sort of testing. What I'm interested in is clicking the applet's buttons, reading off text values, and the like. Thanks!

  • Passing parameters to a flash movie inserted in a VB program

    - by Michael
    Hi! I need to insert a Flash movie in a Visual Basic 2008 express form and send parameters to the movie, but am a newbie to VB. The flash movie will plot points sent by VB in a graph. I tried to insert the Shockwave Flash control in the form but cannot find it anywhere. So I inserted the webbrowser control, which I understand can be used to a similar purpose. But how would I send the values of X and Y (coordinates to plot in Flash) to the flash swf? Thanks for any help!

  • Perl Imager::Screenshot not doing screenshot with default parameters

    - by Grigor
    I have the following code: use Imager::Screenshot 'screenshot'; my $img = screenshot(hwnd => 'active', left => 450, right => 200, top => 50, bottom => 50); $img->write(file => 'screenshot.png', type => 'png' ) || print "Failed: ", $img->{ERRSTR} , "\n"; it returns: "Can't call method "write" on undefined value at line 3" but when I do: use Imager::Screenshot 'screenshot'; my $img = screenshot(hwnd => 'active', left => 100, right => 300, top => 100, bottom => 300); $img->write(file => 'screenshot.png', type => 'png' ) || print "Failed: ", $img->{ERRSTR} , "\n"; it does take a screenshot. Why would the left, right, top and bottom values matter here?

  • Run a JGNAT program?

    - by anta40
    I just installed JGNAT on Windows (gnat-gpl-2010-jvm-bin.exe) This is a sample code hello.adb from the included manual: with Ada.Text_IO; use Ada.Text_IO; procedure Hello is begin Put_Line ("Hello GNAT for the JVM."); end Hello; First, compile it: jvm-gnatmake hello.adb jvm-gnatcompile -c hello.adb jvm-gnatbind -x hello.ali jvm-gnatlink hello.ali Looks fine.

  • Django - Specifying default attr for Custom widget

    - by Pierre de LESPINAY
    I have created this widget class DateTimeWidget(forms.TextInput): attr = {'class': 'datetimepicker'} class Media: js = ('js/jquery-ui-timepicker-addon.js',) Then I use it on my form class SessionForm(forms.ModelForm): class Meta: model = Session def __init__(self, *args, **kwargs): super(SessionForm, self).__init__(*args, **kwargs) self.fields['start_time'].widget = DateTimeWidget() self.fields['end_time'].widget = DateTimeWidget() No css class is applied to my fields (I'm expecting datetimepicker applied to both start_time & end_time). I imagine I have put attr at a wrong location. Where am I supposed to specify it ?

  • Inno Setup: Set default value for desktop icon-check box to true

    - by MB
    I am struggling with getting Inno Setup to set the check box to true whether a desktop icon should be created. The documentation has not been any helpful concerning this issue as well as Googlism and Stackoverflow. [Tasks] Name: "desktopicon"; Description: "{cm:CreateDesktopIcon}"; GroupDescription: "{cm:AdditionalIcons}"; Flags: unchecked My thought was a value like "checked" for "Flags" but the documentation told me, that Flags isn't responsible for this.

  • use doctest and logging in python program

    - by Luke
    #!/usr/bin/python2.4 import logging import sys import doctest def foo(x): """ foo (0) 0 """ print ("%d" %(x)) _logger.debug("%d" %(x)) def _test(): doctest.testmod() _logger = logging.getLogger() _logger.setLevel(logging.DEBUG) _formatter = logging.Formatter('%(message)s') _handler = logging.StreamHandler(sys.stdout) _handler.setFormatter(_formatter) _logger.addHandler(_handler) _test() I would like to use logger module for all of my print statements. I have looked at the first 50 top google links for this, and they seem to agree that doctest uses it's own copy of the stdout. If print is used it works if logger is used it logs to the root console. Can someone please demonstrate a working example with a code snippet that will allow me to combine. Note running nose to test doctest will just append the log output at the end of the test, (assuming you set the switches) it does not treat them as a print statement.
