AccessViolation-Error mit DLL

[jamma-markus]

hi,

ich bekomme jedes mal, wenn ich die prozedur "set_lang_values" aufrufe einen EAccessViolation-Error. die procedure hängt in einer dll.

Aufruf der Prozedur:
set_lang_values(language, mm_file, mm_exit, bt_add, bt_change, bt_del, bt_exit); Prozedur

Delphi-Quellcode:

procedure set_lang_values(
  language : TLanguage_values;
  mm_file, mm_exit : TMenuItem;
  bt_add, bt_change, bt_del, bt_exit : TBitBtn); stdcall;
begin
//Mainmenü
  mm_file.Caption := string(language[0,0]);
  mm_exit.Caption := string(language[0,1]);
//Buttons
  bt_add.Caption := string(language[1,0]);
  bt_change.Caption := string(language[1,1]);
  bt_del.Caption := string(language[1,2]);
  bt_exit.Caption := string(language[1,3]);  
end;

language ist so deklariert

Delphi-Quellcode:

type
  TLanguage_values = array [0..5, 0..50] of PChar;  

var
  language : TLanguage_values;
