• fire an intent from the onCreate method in android

  - by Sephy

  Maybe my question might seem a bit weird, but I have an activity in which, in one case , I have to move to another activity before it finishes loading the screen. My condition is in the onCreate method, which means when I encounter it, i get a "startActivity called from outside an activity context" error and the app just crashes... But then, is there an easy way like a flag for the intent to make it work without having the activity context resolved? thanks for any answer

• how to tell which object called a delegate method (objective c)

  - by user353877

  Let's say you have two objects (UITextviews) in your class. When the text view changes, you have a delegate method that catches the change.. but how can you tell programatically WHICH object was changed and called the delegate ?? I have to be missing something, because this should be trivial, but I couldnt find anything. Note: In this case, its not possible to just break up the class to only have one object (there by bypassing ambiguity).. I looked for things like assigned variable names for nsobjects, nothing there

• Javascript equivalent of Python's iterkeys() dictionary method

  - by saltycrane

  In Python I can use the iterkeys() method to iterate over the keys of a dictionary. For example: mydict = {'a': [3,5,6,43,3,6,3,], 'b': [87,65,3,45,7,8], 'c': [34,57,8,9,9,2],} for k in mydict.iterkeys(): print k gives me: a c b How can I do something similar in Javascript?

• .NET IsValidXml Extension Method Performance

  - by tyndall

  I have a legacy application that I inherited that passes a lot of XML around as Strings. I often need the ability to check if a String will be valid XML. What is the fastest and least expensive way to check if a string is valid XML in .NET? I'm working in .NET 3.5 and would most likely use this as an extension method (off of string) in this one project within the solution.

• J2SE Client Server App: Client calls RMI method. Server handles RMI method and returns, but Client

  - by Mike

  J2SE Client Server App: Client calls RMI message. Server handles RMI method and returns, but Client never receives it. Any ideas how this could happen? Our attempted solution is to set client read timeouts and come up with a framework for resending requests or otherwise handling those failures gracefully. But really, I'd like to know any root causes for how this might happen rather than addressing the symptoms.

• How do I pass an ArrayList to method that takes a collection as an input

  - by Ankur

  I want to pass some ArrayList X into method a(Collection someCol) that takes Collection as an input. How can I do this? I thought an ArrayList was a Collection and thus I should be able to "just do it" but it seems that Collection is an interface and ArrayList implements this interface. Is there something I can do to make this work ... if you understand the theory that would also help me and possibly lots of other people. Thanks
