QUESTION

C++ convertStringToByteArray to Delphi convertStringToByteArray

Asked 2022-Apr-09 at 22:28

Im trying to use the GlobalPlatform library from Karsten Ohme (kaoh) in Delphi. Thanks to the help of some people here on stackoverflow i got it parially working and i am able to setup a connection to the cardreader. Now i am trying to select an AID, and therefore i need to pass the AID as array of Bytes to the function.

I use the GPShell (the commandline tool that uses the same library) source code as a reference to help me translate the functions. There i found the convertStringToByteArray function, which takes a string and converts it to a array of Bytes.

The original C++ function:

The original C++ code parses pairs of hex digits into bytes:

A000000003000000 -> A0 00 00 00 03 00 00 00

But your Delphi code is parsing individual hex digits into bytes instead:

A000000003000000 -> A 0 0 0 0 0 0 0 0 3 0 0 0 0 0 0

Try this instead:

QUESTION

Public static readonly vs passing a reference

Asked 2021-Sep-27 at 09:07

For a school project I have to design a system using UML, only I have ran into a problem.

Let's say that I have to design a (somewhat overcomplicated) vending machine. It has a class with the Creator pattern that makes controllers: VendingMachine. This class makes a SaleController object for every sale. The machine supports different kinds of payments, so the SaleController creates a Payment object. The job of this class is to request a payment with the CoinMachine or CardReader classes, based on a user input. However, it obviously needs a reference to the CardReader and CoinMachine objects, which are created by the the VendingMachine class.

Would it be better to create a public static readonly object reference in the VendingMachine? Or to pass an object reference to SaleController and then pass it on to Payment?

Thanks!

It seems to me that you need a PaymentService that is able to encapsulate such logic. This PaymentService would be the one deciding whether to use CardReader or CoinMachine to process the Payment object.

CardReader and CoinMachine should be dependencies of PaymentService. If you are using Spring, you could create CardReader and CoinMachine Beans by annotating them with @Component and in PaymentService you just need to make them dependencies (injected via @Autowired or constructor). If you are not using Spring or any other similar Inversion of Control Framework, your best option would be to create CardReader and CoinMachine instances on PaymentService and keep them as attributes.

SQL query in Excel throwing 'Missing Right Parenthesis' error

Asked 2021-Feb-05 at 15:44

Disclaimer: I am not a developer, I have no intimate knowledge of SQL.

I was handed an Excel document that has ODBC connections to our Oracle database. There are several queries, and this is not technology that I've used for this purpose before. I've figured out all queries except for one, and I keep getting an error:

[Oracle][ODBC][Ora]ORA-00907: missing right parenthesis error.

I believe I've validated all parentheses, and I've validated the presence of single quotes where appropriate - I cannot figure out where a syntax error would be. Is there anyone who can help?

Here is a much quicker way to find a formatting error in a large query as opposed to reviewing a 200-line query. Download Oracle SQL Developer (free), and paste the query in a sql window, try executing it. I pasted your query in, and tried to execute it. Get the error below:

The problem is that you are attempting to convert your CLOBs to VARCHAR2s when using the TO_CHAR function. REGEXP_SUBSTR can take CLOBs as the input parameter so try not casting the CLOBs, instead cast the result of the REGEXP_SUBSTR to be compared with SICIL_KOD.
