How to do this using Delphi

I am using RAD Studio XE6. I want to know how to extract characters from a Edit Box that is I have something like EDABoard in EditBox and I want to extract one character at a time from the EditBox like 'E', 'D', 'A', .... and also want to get the ascill value of the charcaters of each extracted characters.

The entire content of the EditBox is held in its Text property like this: EditBox1.Text
To get one character from that just use an index. EditBox1.text[1] is the first character in the string.
To get the ASCII value of a character use the ord function.
So you could have something like this:

Code:

var
  ASCII_Val : byte;
  i : integer;
begin
  for i := 1 to length(Edit1.Text) do
  begin
    ASCII_Val := ord(Edit1.Text[i]);
    // Do whatever you want with the ASCII value here
  end;
end;
