PHPLinkDirectory Unicode UTF-8 Characters Display Problem Solved

dcsaha — Fri, 12 Aug 2011 15:58:18 +0000

By default PHPLinkDirectory does not display unicode utf-8 coded characters. You need to change the init.php file at the root of your phpld directoy.

Edit init.php in both home directory of your phpld installation and the admin directory.

Change:
// $setCharset = $db->Execute (“SET NAMES ‘utf8′”);
// $setCharset = $db->Execute (“SET CHARACTER SET utf8″);

to:
$setCharset = $db->Execute (“SET NAMES ‘utf8′”);
$setCharset = $db->Execute (“SET CHARACTER SET utf8″);

MS Access Exported Query Expression Truncated at 255 Characters

dcsaha — Thu, 11 Aug 2011 17:26:30 +0000

MS Access exported query expressions usually get truncated at 255
Characters. Instead of exporting the query result directly, insert the
query result into “a table with Memo field”. Then export “the table with
memo field”. The solution detail can be found here: http://support.microsoft.com/kb/178743

Java String Comparison

dcsaha — Thu, 02 Jun 2011 19:00:44 +0000

To compare Strings for equality, don’t use ==. The == operator checks to see if two objects are exactly the same object. Two strings may be different objects, but have the same value (have exactly the same characters in them). Use the .equals() method to compare strings for equality. Similarly, use the .compareTo() method to test for unequal comparisons. For example,

    String s = "something", t = "maybe something else";
    if (s == t)      // Legal, but usually WRONG.
    if (s.equals(t)) // RIGHT
    if (s > t)    // ILLEGAL
    if (s.compareTo(t) > 0) // CORRECT>

There are many Twitter application that makes life easier for regular twitter users. One of the breeds of such application is having auto-tweeting capabilities.

Ability to spin and twist your tweets will ensure that your posts are fresh and natural. This is very important. Tweetinger will ensure this very thing that your tweets are spontaneous and not a mechanical output“. Let’s see how it turns out.

How do I format a number with leading zeros, in Java?

dcsaha — Thu, 05 May 2011 16:14:16 +0000

This is an example using java.text.DecimalFormat class to add leading zeros to a number. The method shown is available before Java 1.5
import java.text.DecimalFormat; import java.text.NumberFormat; public class NumberFormatLeadingZerosExample { public static void main(String[] args) { NumberFormat formatter = new DecimalFormat("0000000"); String number = formatter.format(2500); System.out.println("Number with lading zeros: " + number); } }

The following example shows you how to use the String.format() method to add zero padding to a number. If you just want to print out the result you can use System.out.format(). This method is available since Java 1.5, so If you use a previous version you can use the NumberFormat class shown above.
public class LeadingZerosExample { public static void main(String[] args) { int number = 1500; // // String format below will add leading zeros (the %0 syntax) // to the number above. The length of the formatted string will // be 7 characters. // String formatted = String.format("%07d", number); System.out.println("Number with leading zeros: " + formatted); } }

Downloaded “Zoundry Raven” again. Testing now. Looks like very useful. I think this utility will help me blog frequently as it can be launched from my USB drive also. I can post to any of my multiple blogs from this single utility. Indeed, I can keep all my blogs in my pocket and post a couple of lines to any one of those whenever I am in the mood.
