Zitat von Sharky:

Hai,

das habe ich mal so schnell hingetippelt.

Delphi-Quellcode:

function ExtractiMehl (aValue : string) : string;
var
  at : integer;
  start : integer;
  stop : integer;
  permittedChar : SET of Char;
begin
  permittedChar := ['a'..'z','.','_','-'];
  aValue := AnsiLowerCase(aValue);
  at := Pos('@',aValue);
  start := at-1;
  while (aValue[start] in permittedChar) and (start > 0) do
  begin
    Dec (start)
  end;
  stop := at+1;
  while (aValue[stop] in permittedChar) and (stop < length(aValue)) do
  begin
    Inc (stop)
  end;
  result := Copy (aValue,start,(stop-start));
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
  Label1.Caption := ExtractiMehl(Edit1.Text)
end;

He Sharky,

klappt !!!!

vielen lieben Dank!

Gruss
