  - by Blankman

  In my code, is there a shorthand that I can use to assign a variable the value of a object's property ONLY if the object isn't null? string username = SomeUserObject.Username; // fails if null I know I can do a check like if(SomeUserObject != null) but I think I saw a shorthand for this kind of test. I tried: string username = SomeUserObject ?? "" : SomeUserObject.Username; But that doesn't work.

• jQuery Selectable only select 1 and get a value?

  - by jphenow

  This might seem like an odd request but I'd like to use jQuery's Selectable tool to only select one item at a time and I'd like it to show me a value I'll have within each tag. At the very least I want the contents of that selection. Has anyone tried to do this? For some reason these little things seem to not be all that easily findable in their API for it.

• How to structure a table for additional data if a particular value of an enum/lookup table is chosen

  - by Soliah

  I'd like to store additional data if a particular value is chosen in the enumerated or looked-up column in a table.

• How to modify TaskDialog's Show() call to be blocking and return a value when closed?

  - by JustABill

  I'm using the WindowsAPICodePack's TaskDialog implementation, but it bugs me that I have to listen to click handlers on its buttons for even the more basic implementations. I'd like to convert/wrap it so that like the old MessageBox it blocks until closed and then returns a value based on what was done. Is there anything I can read for the basics on how to do this? I just have no idea where to even start, as I am admittedly not that familiar with the Win32 underpinnings.

• How to generate a random BigInteger value in Java?

  - by Bill the Lizard

  I need to generate arbitrarily large random integers in the range 0 (inclusive) to n (exclusive). My initial thought was to call nextDouble and multiply by n, but once n gets to be larger than 253, the results would no longer be uniformly distributed. BigInteger has the following constructor available: public BigInteger(int numBits, Random rnd) Constructs a randomly generated BigInteger, uniformly distributed over the range 0 to (2numBits - 1), inclusive. How can this be used to get a random value in the range 0 - n, where n is not a power of 2?
