I'm Not.. (But I am about to destroy the reputation that I know what I'm
doing :) )
One of the Functions in the Dll looks like this:
------
function kidfromint(var V1, prefix,lengde : integer) : PAnsichar; cdecl;
export;
var
formatertNR : string;
pre : char;
begin
formatertNR := trim(inttostr(V1));
Try
if lengde-1 > length(formatertNR) then
begin
while length(formatertNR) < lengde-1 do formatertNR :=
'0'+formatertNR; //LeftPadd 0 til lengde
if prefix > 0 then pre := (inttostr(prefix)[1]);
begin
formatertNR[1] := pre;
end;
end;
formatertNR := formatertNR
+trim(string(kontrollsifferfromstr(PAnsichar(formatertNR))));
Result := PAnsichar(formatertNR);
except
Result := '';
end;
end;
------
If this helps. Is it just luck that it works on a Window Server ?.
