The promps from this dialog can be modified from a database, string by string.
The database is called : AstCrtlDb.mdb, and can be found in C:\ProgramData\Graitec\AdvanceSteel\2010\Steel\Data
Here, open the table : ErrorMessages.
The lines containing string text for the names present in the Advance Copy dialog can be found starting with line : 8676 -> 8709 (see attached picture). Changing those names in the ErrorText column will influence the dialog in the program.
