I am currently building a custom container control. Everything was going along smoothly until I hit a snag during testing.
I noticed that the Enter key is not getting processed to the control that has focus inside the container. Everything else works as expected though. I am able to click the button with either the mouse or space bar, but enter…
I'm trying to implement some basic entities using Hibernate/JPA. Initially the code was deployed on MySQL and was working fine. Now, I'm porting it over to use PostgreSQL. In MySQL, my entity class defines its primary key as an auto-incrementing long value with the following syntax:
@Id
@GeneratedValue(strategy = GenerationType.AUTO)

If I create an array of strings (via key-value coding) containing the names of a Managed Object entity's attributes which are stored in the App Delegate the first time, I get an array of NSStrings without any problems. If I subsequently make the same call later from the same entry point in code, that same collection becomes an array of…

I want to cache that data in an array table for use later within a web page but I want to keep the keys from the query and separate out each grouping within a multidimensional array. However to save time iterating through…

I've got a ThinkPad W530 laptop, which replaces the Application Key (also known as Menu Key or Mouse Right Click key, usually between Right Alt and Right Ctrl) with the Print Screen key.
So, I need to replace Prt/Scr with Application key. That's easy, all key mapping software like SharpKeys or whatever can do that. There…

Hello everyone. I'm trying to determine the best course of action to implement a simple "licensing" system with a partner of mine. The concept is:

I'm using an Apple bluetooth keybord to control my Linux synergy server. SSH tunneling, Mouse, Keyboard, and Copy&Paste all work.

Why does Java not provide functions to get at the key/value pairs in a HashSet like in Hashtable? It seems like a real pain to have to iterate over it every time you need to get at something. Or am I just a newb missing something?
Most of the time,we just get the result from database,and then save it in cache server,with an expiration time.
When do we need to persistent that key/value pair,what's the significant benifit to do so?
