Scanning Datamatrix Codes in wxWidgets Application

[gbuergisser]

Hi all,

The application I'm developing allows the user to input data manually or by scanning a 2D datamatrix code. As you may know the datamatrix code can contain binary control characters, e.g. \x1d aka GS aka Group Separator, to terminate variable length data in the code.

Now if I scan a datamatrix into a wxText control, the GS character is stripped from the input. How can I suppress this behaviour?

Thanks for any help.

I don't think you can make the text control store non-printable characters. I would try to catch the key event early and store the data in a separate buffer.
