MDIChild form from an MDIChild form in C #
I was working in a MDI Desktop Application, and I was looking for a way to open a new form (send some parameters) and make this new form a child of my MDIControl Form or main Form. I didn’t have to much luck looking around for an answer on Forums so here I post a very simple solution that I came up with.
I hope this help someone in need out there :)

The most important part of a GSM network is so called Base Transceiver Station (BTS). These transceivers form the areas called cells (this term gave the name to the cellular phone) and every phone connects to the BTS with the strongest signal (in a little simplified view).

JRuby 1.6.2 + Netbeans 7 + Windows 7
As everyone knows now, there is not official support for ruby in the new Netbeans 7. That’s sad, but there is a way (at your own risk) that we can make this combo works:

2. Set name to “beta 1”
3. Set URL to ‘http://updates.netbeans.org/netbeans/updates/7.0/uc/beta/stable/catalog.xml.gz’

CodeChef, Peer Problem 1
All submissions for this problem are available.
Reversed number is a number written in arabic numerals but the order of digits is reversed. The first digit becomes last and vice versa. For example, if the number is 1245,it will become 5421 .Note that all the leading zeros are omitted. That means if the number ends with a zero, the zero is lost by reversing (e.g. 1200 gives 21). Also note that...

Here i wrote a method that grab data from a DB, and I used it here to pass it through the screen. First, I get the data from the DB to a Dataset, so I use a Datatable to order my data and then I used a double for-loop to fill the DGV up.
