• WPF WrapPanel - all items should have the same width

  - by John

  I have a ListBox whose ItemsPanel I have replaces with a WrapPanel. The WrapPanel now hosts the databound ListboxItems. Each item has a variable sized text in it, giving each item a different width. However, I want the width to be constant so that all items have the same width as the item with the longest text. Is that possible?

• Not Possible to Reference self in a Method Declaration?

  - by phasetwenty

  I wanted to write a method with an argument that defaults to a member variable like so: def method(self, arg1=0, arg2=self.member): Apparently this is not allowed. Should I write it a different way, or perhaps use a value of arg2 to signal when to use a different value?

• Help to comment a simple statement

  - by Woppie the Russian

  How does you call this statement?: $arr = array(); initialize an array or declare an array? In brief, how would you comment such a statement? (P.S. That array would then hold a bunch of values.) EDIT: I doubt because what I basically do is declare a variable of a particular type, don't I?

• iOS - Prompt User to Update to Latest App Version

  - by Kevin_TA

  Is there any method or plugin available that will alert the user to upgrade an app if the version they are using is not the latest? I suppose I could ping a web service to check what the current version is and compare with the user's version and go from there. As an aside, is there a way to check the current version of the app (some property I don't know about) or do you simply have to hardcode the version as some float variable or something? Thanks

  - by Lily

  I have a string representing bits, such as: "0000101000010000" I want to convert it to get an array of bytes such as: {0x0A, 0x10} The number of bytes is variable but there will always be padding to form 8 bits per byte (so 1010 becomes 000010101).

• Why are member constants available even if there are no instances of a its class?

  - by flockofcode

  1) Why are member constants available even if there are no instances of a its class? 2) Is the only reason why constant expressions need to be fully evaluated at compile time due to compiler replacing constant variable with literal value? 3) Since string is also an object, I would think the following would produce an error, but it doesn’t. Why? class A { const string b = “it works”; } thank you

• static NSStrings in Objective-C

  - by MikeyWard

  I frequently see a code snippet like this in class instance methods: static NSString *myString = @"This is a string."; I can't seem to figure out why this works. Is this simply the objc equivalent of a #define that's limited to the method's scope? I (think) I understand the static nature of the variable, but more specifically about NSStrings, why isn't it being alloc'd, init'd? Thanks~

• Java Definitions

  - by Brian

  I just had a test on java and we had to give the definition of 1) Static: 2) IOExcepion: What I said for static was...a static method is used to define a method as a class method. And I got it wrong so I asked my teacher and he said he wants the actually definition of static not a static method, class or variable just static. Can someone tell me the definition of this and for IOException please Thanks.
