Strange problem with database log in...

Question

Hi all,
I am doing a small interface which will contain the name and password textField for user to log in.
The strange thing is, the program doesn't go through the line
       rec = st.executeQuery( "SELECT * FROM tbladmin WHERE Name ='"+nField.getText()+"' AND Password = '"+pField.getText()+"'" );If I try to display some message before this line, it showing properly but if after that line, nothing happen.

#As long as you put in statements like
catch(SQLException ex)
                { };you don't deserve any help. Sorry.
