Removing a character from a string

Is there a function that will remove a character from a string.  I wrote a little loop to do it for me but the problem is that I don't know how to terminate it the way I want it.  Take a look:

intTemp := pos('''',strTemp2);
if (intTemp > 0) then
begin
     intTemp := intTemp + 1;
     While (strTemp2[intTemp] <> #0) do
     begin
          strTemp2[intTemp - 1] :=    strTemp2[intTemp];
          intTemp := intTemp + 1;
     end;
     strTemp2[intTemp - 1] := #10;
end;

Basically what the code above does is remove any single quotes (') from strTemp2.  So if strTemp2 is 'hershey's' then after the routine it should be 'hersheys'.

The problem I have with this is that the results ends up being 'hersheys'#0.  I don't want that null-terminating character to be there, but I don't know what else I could do.

hi uhoang,

take a look to this procedure

Removes a substring from a s string.

Unit

System

Category

string handling routines

procedure Delete(var S: string; Index, Count:Integer);

Description

Delete removes a substring of Count characters from string S starting with S[Index]. S is a string-type variable. Index and Count are integer-type expressions.

If Index is larger than the length of S, no characters are deleted. If Count specifies more characters than remain starting at the S[Index], Delete removes the rest of the string.

hi again,

a little sample

Function StripChar(AString : String; AChar : Char) : String;
var
  P : Integer;
  S : String;
begin
  S := AString;
  P := pos(AChar,S);
  While P > 0 do
  begin
    Delete(S,P,1);
    P := pos(AChar,S);
  end;
  Result := s;
end;

//sample to call
procedure TForm1.Button1Click(Sender: TObject);
var s : string;
begin
  edit1.Text := StripChar(edit1.Text,'.');
end;
