Sometimes you want to format a string with leading or trailing spaces or other characters. The Pad() function will do that for you. Say you have a string '123', but you want it to read '000123'. Simply call it like this: tmpStr := Pad('123', 6, '0', _LEADING);
type
PadType = ( _LEADING, _TRAILING );
function Pad ( targetStr: string;
targetLength: byte;
PadChar: string;
PadType: PadType ): string;
var
i, startLength: Byte;
begin
{ Make sure padchar is a 1-char string; }
{ default it to the space char. }
PadChar := PadChar + ' ';
PadChar := copy(PadChar, 1, 1 );
{ Pad the string }
startLength := Length( targetStr );
if startLength < targetLength then
for i := startLength + 1 to targetLength do
begin
if PadType = _LEADING then
TargetStr := PadChar + TargetStr
else
TargetStr := TargetStr + PadChar;
end;
Result := TargetStr;
end;
