SystemStrLIComp (Delphi)

Description

This example requires two text edits and a button. Enter text in the two text edits and click the button to compare the strings, without case sensitivity.

Code

procedure TForm1.Button1Click(Sender: TObject);
var
  S1, S2: String;
  Pos: Integer;
  Equal: Boolean;
begin
  Pos := 1;
  Equal := True;
  S1 := Edit1.Text;
  S2 := Edit2.Text;
  Form1.Repaint;
  while (Equal = True) do
  begin
    if StrLIComp(PChar(S1), PChar(S2), Pos) = 0 then
      Inc(Pos)
    else
      Equal := False;
  end;
  Canvas.TextOut(10, 10, 'The first ' + IntToStr(Pos - 1) +
    ' characters are equal.');
end;
