  • Why can one null return be tested but another throws an exception?

    - by mickey
    I want to test if an xml attribute is present. Given this: XmlAttributeCollection PG_attrColl = SomeNodeorAnother.Attributes; This first test works: if (null != PG_attrColl["SomeAttribute"]) "GetNamedItem" is supposed to return null, but the following test throws an exception complaining about the null it returns. if (null != PG_attrColl.GetNamedItem("SomeAttribute").Value;) Why the difference? Just curious.

  • Objective C: Compare timeInMillis with current time

    - by Srivathsan Canchi
    Hello, In my iPhone application, I need to calculate the time difference between the time a message was created on the server, and the time my phone received it. The server (Java) puts in a number returned by System.currentTimeMillis() as metadata along with the message. How do I compare this number with the current time on the device? Could not find a suitable NSDate method to do this comparison. Thanks in advance!

  • jquery document height reported incorrectly by IE (on XP) first time

    - by Zhami
    I'm having a "first time" problem with IE, which reports a different value for $(document).height(); when the page first loads versus subsequent queries. The difference is 17 pixels regardless of the opening size of the window -- on document ready, the height reported is 17 pixels larger than is subsequently reported. I wonder if this is an artifact of some aspect of my page (some margins or paddings somewhere), but so far can't account for 17 pixels.

  • Will First() perform the OrderBy()?

    - by Martin
    Is there any difference in (asymptotic) performance between Orders.OrderBy(order => order.Date).First() and Orders.Where(order => order.Date == Orders.Max(x => x.Date)); i.e. will First() perform the OrderBy()? I'm guessing no. MSDN says enumerating the collection via foreach och GetEnumerator does but the phrasing does not exclude other extensions.

  • Qt releasing memory occopied by unneeded images

    - by Gerhman
    I have a QML Flickable with 3 QML image elements that cycle through 8 image files. My problem is for each new image it loads into memory it does not release the the unused image. This is causing memory usage to become double what is necessary at times. I would like to know if there is some function I can use to force it to unload all the unused images? If it makes a difference, this is mainly for Symbian.

  • Update one list from another

    - by lacqui
    I have two multi-select lists in HTML - one of categories, and another of items. What I want is that, when an item selected in the "category" list, everything in the "items" list from that category is also selected. For example, if "Categories" contains "Animal", "Mineral", and "Vegetable", and "Items" contains "Dog", "Cat", "Monkey", "Diamond", "Granite", "Carrot", "Tomato": If "Animal" is selected in one list, "Dog", "Cat", and "Monkey" should be selected; any other selections should remain as they are. I'm using a Symfony PHP backend on the server, if that makes any difference

  • speed of map() vs. list comprehension vs. numpy vectorized function in python

    - by mcstrother
    I have a function foo(i) that takes an integer and takes a significant amount of time to execute. Will there be a significant performance difference between any of the following ways of initializing 'a': a = [foo(i) for i in xrange(100)] , a = map(foo, range(100)) , and vfoo = numpy.vectorize(foo) vfoo(range(100)) ? (I don't care whether the output is a list or a numpy array). Is there some other better way of doing this? Thanks.

  • Using Variables for Class Names in Python?

    - by Sam McAfee
    I want to know how to use variables for objects and function names in Python. In PHP, you can do this: $className = "MyClass"; $newObject = new $className(); How do you do this sort of thing in Python? Or, am I totally not appreciating some fundamental difference with Python, and if so, what is it?
