X++ character encoding?

(0) ShareShare
ReportReport
Posted on by bankk 6,611

Hello.

Are there libraries available within X++ to modify the character encoding from UTF-8 to ANSI? We're sending native label format instructions to a thermal printer. The format is stored in a SQL table but once retrieved the character set or encoding is changed so when it's sent to the printer the encoded logo does not print. I used Notepad++ to view the label data prior to storing it in AX and after it retrieved for printing from AX; Notepad++ shows the working set as "ANSI" (5K file size) while the non-printing logo version is "ANSI as UTF8" (8K file size). Any help would be greatly appreciated. Thank you.

    X++ offers some limited options, e.g. the codepage parameter of TextIo's constructor. Nevertheless you can do much more with System.Text.Encoding class and its specific implementations.

    This is just a generic answer because I don't know your specific situation.

    Martin, many thanks for the reference. Using TextIo and its codepage parameter, I was able to take in a UTF file, converted it to ACP, wrote it out to a file, sent the file to the printer and it worked great.

    My situation is a bit different in that I would retrieve the data from a query, then need to convert it to a different encoding, then using a StreamWriter to send the data directly to the printer. Could you enlighten me on how .Net objects would be referenced in the context of a X++ class?

    You can use .NET objects directly in X++ thanks to .NET Intereop from X++. It has some limitations, such as the need for fully qualified names, no support for generics, the fact that X++ doesn't understand properties etc., but it's a great tool anyway. I use it really often.

    For example, this is valid X++ code (if I didn't make any mistake):

    System.Text.UTF8Encoding utf8 = System.Text.Encoding::get_UTF8();

    Martin, I'm very appreciative of the information you've provided. Though they didn't directly resolve my issue, as you had already cautioned me, but they did lead me ultimately to a solution. Many thanks!
