Hi, Topiccategories list retrives data but I have made small test and wanted to save simple test data. Below is the code. Unfirtunately when I open checkboxprop.properties I can't see any data. Maybe property file must be located in any special place in project. I don't know. Can you help. Regards, Rafal
try
{
FileOutputStream fos =
null
;
properties.store((fos =
new FileOutputStream("checkboxprop.properties")), "Author: jasonX"
);
fos.close(); System.
out.println("Data are saved"
);
}
catch
(IOException e) {
System.
out.println("Error"
);
