Hello guys

I have a function that is not working so fine.

I'd like to run all of over my text and look for a determine word in determine color and change it to another color.

I did a function, but it doesn't work the way that it should be.

Maybe a hand can help me to reach my goal.

This is my code:

procedure ChangeWordColor(RE: TRichEdit; TheWord: String; Color: TColor; Style: TFontStyles);
var
  i, CharPos, noChars: Integer;
begin
  CharPos := 0;
  noChars := 0;
  for i := 0 to Pred(RE.Lines.Count) do
  Begin
    noChars := noChars + Length(RE.Lines[i]);
    CharPos := RE.FindText(TheWord, CharPos, noChars, [stWholeWord]);
    RE.SelStart := CharPos;
    RE.SelLength := Length(TheWord);

    if RE.SelAttributes.Color = clRed then
    Begin
      RE.SelAttributes.Color := color;
      RE.SelAttributes.Style := Style;
    End;
  End;
end;

Try this...
Procedure ChangeWordColor(RE:TRichEdit;TheWord:string; TheColor: TColor; TheStyle: TFontStyles);
Var
FoundAt : integer;
len: integer;
start_pos: integer;
begin
    start_pos:=0;
    len:=RE.GetTextLen - Start_Pos;
    FoundAt:=RE.FindText(TheWord,start_pos,len,[stWholeWord]);
    while FoundAt <> -1 do
    begin
      RE.SelStart := FoundAt;
      RE.SelLength := Length(TheWord);
//      if RE.SelAttributes.Color = clRed then Begin
        RE.SelAttributes.Style := TheStyle;
        RE.SelAttributes.Color := TheColor;
        RE.SelText :=TheWord;
//      End;
      start_pos:=RE.SelStart+RE.SelLength;
      len:=RE.GetTextLen - Start_Pos;
      FoundAt:=RE.FindText(TheWord,start_pos,len,[stWholeWord]);
    end;
end;
