...einen String parsen?
Autor: Johan Stokking
// Parse a string, for example:
// How do I get the "B" from "A|B|C|D|E|F"?
function Parse(Char, S: string; Count: Integer): string;
var
I: Integer;
T: string;
begin
if S[Length(S)] <> Char then
S := S + Char;
for I := 1 to Count do
begin
T := Copy(S, 0, Pos(Char, S) - 1);
S := Copy(S, Pos(Char, S) + 1, Length(S));
end;
Result := T;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
ShowMessage(Parse('|', 'A|B|C|D|E|F', 2));
end;
{
Parameters:
Parse([Character, for example "|"], [The string],
[The number, the "B" is the 2nd part of the string]);
This function is handy to use when sending data over the internet,
for example a chat program: Name|Text. Note: Be sure there's no "Char" in the string!
Use a unused character like "|" or "×".
