==== About software tools to synchronize with subversion ====

**2013/03/22 update:** I've tried subversion in a Windows machine and I found out that it doesn't work because it requires a connector and the instructions to download the connector are not easily found. I recognize that I gave up at first difficulty, but talking about plugins, I don't give them many opportunities. Moreover, I found that the //subclipse// plugin has more popularity.

I have a 64 bit laptop --Intel--. I usually develop java in there. I found that the subclipse plugin for subversion crashes frequently, but the [[http://www.eclipse.org/subversive|Subversive]] doesn't. For anyone that may be interested.

And by the way, if you are planning to download something from sourceforge, choose SVN Kit 1.3.2 connector compatible with version 1.6.x of subversion. See this: http://sourceforge.net/scm/?type=svn&group_id=80882.

==== Launching a java batch file from a visual basic script ====

<code vbscript>
'
' sisyphus.vbs
'


dim osh 
dim classpath

classpath="./;./CopyTables.jar;./lib/*"

set osh = createobject("wScript.shell") 

' get the variables of the "process" environment
set objEnv = osh.Environment("Process")

objEnv("CLASSPATH") = classpath

osh.run "java App -Dorg.apache.commons.logging.Log=log4j.properties >> console.log 2>>error.log",1

==== Formatear fechas y números ====

Un ejemplo de tres formateadores: uno para fechas, otro para horas, y otro para números. Estos formateadores van a usar los formatos "a capón" en lugar de usar los que provee por defecto Locale, que debería ser la forma correcta de usarlos para que la aplicación fuese internacionalizable. 

<code java>

import java.text.DecimalFormat;
import java.text.DecimalFormatSymbols;
import java.text.SimpleDateFormat;
import java.util.Locale;

SimpleDateFormat formatDate = new SimpleDateFormat("dd/MM/yyyy");
SimpleDateFormat formatDateFecharea = new SimpleDateFormat("yyyyMMdd");

SimpleDateFormat formatTime = new SimpleDateFormat("HH:mm");
DecimalFormat formatNumber = new DecimalFormat("#,###.##");

DecimalFormatSymbols symbols2 = new DecimalFormatSymbols(Locale.US);
DecimalFormat formatNumberUS = new DecimalFormat("#,###.##", symbols2 );

</code>

==== Parsing a Date in Java ====

<code java>

try {
    // Some examples
    DateFormat formatter = new SimpleDateFormat("MM/dd/yy");
    Date date = (Date)formatter.parse("01/29/02");

    formatter = new SimpleDateFormat("dd-MMM-yy");
    date = (Date)formatter.parse("29-Jan-02");

    // Parse a date and time; see also
    // Parsing the Time Using a Custom Format
    formatter = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss");
    date = (Date)formatter.parse("2002.01.29.08.36.33");

    formatter = new SimpleDateFormat("E, dd MMM yyyy HH:mm:ss Z");
    date = (Date)formatter.parse("Tue, 29 Jan 2002 22:14:02 -0500");
} catch (ParseException e) {
}
