you can use some thing like this ,

function getuserlogin:string;
var pcusername:pchar; xchars:dwords; valor:integer;
begin
valor:=255;
xchars:=255;
pcusername:=strAlloc(valor+1);
getusername(pcusername,xchars);
result:=string(pcusername);
end;

Procedure onclick(sender:tobject)
begin
 edit1.text:=getuserlogin();
end;

Function LoggedName : string;
var
   sizeOfuser : cardinal;
   user : array[0..255] of char;
begin
   sizeOfuser := sizeof(user);
   IF getusername(user,sizeOfuser) = true then
   Begin
      Result := string(user);
   End
   Else
      Result := 'NO USER';
end; { LoggedName }

now you just need to call the function
ex:
   Edit1.Text := LoggedName;
