Your frame is covered by a gray frame thats why paint method do not show anything.

Yes that didn't come to my mind...thank you :)

You should have a database layer. It should NOT have any gui code in it. It provides a public API that allows an external caller to interact with the layer. The layer interacts with the database. That public API would have a method/class that would represent "save interval" and "get interval" where the 'interval' values represent '1 month', '3 Months', '6 months' (and note that I am NOT saying to store "1 month" as a value.) The 'save' method uses a database insert or perhaps update statement. And the 'get' uses a database query statement. You code that and test it. After you do that THEN your gui code, specifically the JSpinner uses the two methods.

Thanks for the Idea. :)

thanks a lot :)

I have got the solution I have created two Printer Job 1. PrinterJob job = PrinterJob.getPrinterJob(); PrinterJob pj = PrinterJob.getPrinterJob(); And If I did this in my code job.setPrintable(this); I should not be doing this if (pj.printDialog() == true) pj.print(); Instead of "pj" I have to use "job". that was the problem I was not using the right job hehe.

Change Listener works fine .

To add anything in scrollPane , try this jscrollpane.setViewPortView(...) Regards Shubhashish

Yes now I know my mistake,thank you :)

You should go back to your Java documentation or tutorials and learn why and when it is possible to use casts. Simply stated, you cannot use a cast to convert one object type to another. You also need to decide in advance what object type you want to store in the database, and write the code to handle that specific situation. Veni, vidi, abiit domum

Are you using a SQL Express User Instance[^] (AttachDBFilename in your connection string)? These databases will automatically be closed and removed after a period of inactivity, which is why you can't see them in SQL Server Management Studio. "These people looked deep within my soul and assigned me a number based on the order in which I joined." - Homer

public class ConClass { public Connection con = null; // constructor to initialize con. public ConClass(DataSource ds){ try{ con = ds.getConnection(); } catch(SqlException ex){ System.out.println(ex.getMessage()); } } // the con to get. public Connection getCon(){ return con; } } public class SaveData { private Connection con = null; public void save(ConClass cObj){ if(con == null){ con = cObj.getCon(); } // do whatever and use whenever you want your con in this class. } }

By the way, your function createSalt() creates a new salt every time you call it! When you want to compare the original value and the database value, you hat to write the salt into a variable, then set it to your object, write to database, then retrieve from the database.

You shouldn't need to, that means anyone else can, and your system is not secure. Passwords should use one-way hashes so they can never be converted back to the original string. See Secure Password Authentication Explained Simply[^]. Use the best guess
