• Getting a date value in a postgres table column and check if it's bigger than todays date

  - by Roland

  I have a Postgres table called clients. The name column contains certain values eg. test23233 [987665432,2014-02-18] At the end of the value is a date, I need to compare this date, and return all records where this specific date is younger than today I tried select id,name FROM clients where name ~ '(\d{4}\-\d{1,2}\-\d{1,2})'; but this isn't returning any values. How would I go about to achieve the results I want?

• 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?

• How to assign a value of a property to a var ONLY if the object isn't null

  - 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.

• Is there a way to get each row's value from a database into an array?

  - by Guyver

  Say I have a query like the one below. What would be the best way to put each value into an array if I don't know how many results there will be? Normally I would do this with a loop, but I have no idea how many results there are. Would I need run another query to count the results first? <CFQUERY name="alllocations" DATASOURCE="#DS#"> SELECT locationID FROM tblProjectLocations WHERE projectID = '#ProjectName#' </CFQUERY>

  - (void)applicationDidFinishLaunching:(UIApplication *)application{ // Override point for customization after application launch [window makeKeyAndVisible]; [self printFloat:1.3f]; } - (void)printFloat:(float)f { NSLog(@"%f",f); } I passed the "1.3f" to printFloat, but it was the wrong value (in this case, -2.000000) after "f" received.

• 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. The obvious option is to have an extra column in the table, but this will lead to a mostly empty column and seems to be like bad approach. Is there another option/method of doing this?

• 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.

• 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.
