Search automatically on website and get their content

For my project, i need to insert an EAN (Productcode like 4009900508599) on this website: codecheck.info
In a normal case it isnt really an problem, because you can send the content directly to the website.
On this website, the call is:
https://www.codecheck.info/product.search?q=4009900508599&r=03AOLTBLSbwq8TlZl9bDf72tOekXcyrp8vCBu6pgfYvI-0fuFv40FWCX5XX5Z9DTOlo0J-l3WGmSRRUMmxGLl_oO9miNeJExZsrZwbaFFDovw5FrOMaM2CeuOTFQOMr4q__ixGx7jV7509DF_y7Y19maVN40kuCrjIE7JCV7p3uiu4DhOgU6BVlW8O5yrx8px7_fknOwseOiLXIFbxDlbZ6nD-67765YdL6zOiyoH3nHL1LO1L0_GQQkPOrP3QnjXHjjaDzg_RYT48cvkGnt3ER-8AUwB9LPwP-9OJp4uWzxtG-TiWngZEwzcJDJS4FEfsd2Xq2taU7sOhZquEiwi4pFdXQgAwb0PRYNEv9GR1tBb0LYnHUiF9LLMwOhvL3pnaididlwl--jMP_-ZvSnK04EHIKYKQm5CLPbgcfs68iC4GtWnLv63g6hD_W_1kElHdhR3rT_VdAhkjESo7CGcmUyKJ_TVw3Xy4rOZS8t3TCJSux98-otnmJh4
With q=03A... they generate some stuff, that i cant know.
So my question is, does someone know a way to insert the number into the searchbox automatically and get their content?

How to make a save function for a java based android app?

I have an app that encrypts inputs and I want to put a save function that will let users access the "notes" at any time. I thought about adding each in output to an ArrayList, but I still don't know how to save it and display it for the user to select. If you need me to clarify anything I'd be happy to. Thanks.

How to run a com add-in (with log-in and password) with VBA (or maybe other solutions)

update post of screenshotsI've got an COM excel add-in (name; Syntess Atrium Office add-in) which has a login button. When pushed i need to give a path to it's location on the server and after that I need a password to log in.
I need to run this Excel file a couple of times each month late at night with a scheduled task, and every time I need to be logged-in for it to function. So to make sure i'm always logged-in I want to create either a VBA script or any other script to push the log-in button, write down the path, hit enter, and then use my password and hit enter again.
The application (VBA excel sheet) runs at night because it takes several hours to create because of it's huge amount of data it takes from our financial database on the server(using the com add-in).
I hope someone can help me out!
I know I can use programs like Acces or even Excel it self for a direct link with the database, but our directors won't allow this, so that's not an option unfortunately.

If you can view the reference in the object browser you can start to get an idea of the functions (if exposed) that you can use.
You can see from the image below that the class DOMDocument60 (XML Document Object Model) has a loadXML function that "loads the document from a string".
Normally you would not have to use the object viewer as this same information is generally provided by the company:
MSDN - MSXML3.0/6.0 - 'loadXML'
However, if there is no public API available you may be able to read through the object and get an understanding of what you can call.
---If you can't find a 'login' function your best bet is to ask the company to expose such a method (function).

Java storing user preferences

I'm making a program with a simple GUI, where the user have to do the login before starting use the program.
I want to store username and password and, if the user check the "Remember me" checkbox, i want that he doesn't need to enter data next time.
I tried doing with Java Preferences API, this way:
private Preferences prefs = Preferences.userRoot().node(this.getClass().getName());
prefs.put("codCliente", txtCodCliente.getText());
prefs.put("username", txtUsername.getText());
prefs.put("password", DigestUtils.md5Hex(String.valueOf(txtPassword.getPassword())));
But if i close and reopen the app, if i print the content of variables, it returns "Null key" NullPointerException.
I tried to save them in a .properties file, but I don't want to overwrite every time the whole file, and if I try to use apache commons configuration, with setProperty, I can't put the value on the variables.
Which is the best way to store this kind of data?
Thank you all.

Yes preferences is really easy and good way of doing this , problem is that:
he doesn't need to enter data next time
That means he WONT PUT ANYTHING INTO TEXT FIELDS.
But if i close and reopen the app, if i print the content of
variables, it returns "Null key" NullPointerException.
What did you expected? You put this NULL values into preferences again as he starts his app again.
Problem is in your design
application starts->
read preference of checkbox state->
{reread login credentials} else {nothing} ->
show login ui , user enters credentials ->{compare credentials to whose with preferences} DONT STORE ANYTHING , why woud you store what user is trying to login with every single time you start application?
You only store credentials at user creation ,use encryption and store your data, for both name , and password.
In your question there is not enough code to help you out directly with code sample , you have problem with design , where you reading this information in your code? Why dont you post this part here? You only show us that you store soemthing , well ok , thats useless to person thats trying to help you out.
I recommend you to SIT DOWN, stop writing code , and write yourslef flowchart of your application startup and login process all the way with when you read/write anything to preferences etc.
