1 by 1, begin to understand, only print_Text, print_Line succeed  :), 2 others still fail.

just want to bring this 4:
Code: Pascal  [Select][+][-]
  1.     procedure print_line();  overload;
  2.     procedure print_Text(_message: string);  overload;
  3.     procedure print_Custom(_message: string; _size:integer; _align:integer);  overload;
  4.     procedure print_Photo(var _fullFilename: string);  overload;
  5.  

Seems got the failed suspect  -> must be (Ljava/lang/String;II)  :)

Thank you!

for "print_Custom":

Quote
'(Ljava/lang/String;II)V'

But you don't need to code..... Use the code generator as shown in the picture!

And yes, you can generate code for several methods at once .....
