We need a workable function that can strip embedded characters (single qoutes, 
double quotes, etc.,) from within string vars.

Answer:

Solve 1:

Here is a general method to remove characters from a string:


1   type
2     TCharSet = set of Ansichar;
3   
4   procedure RemoveCharacters(var S: AnsiString; const characters: TCharset);
5   var
6     i: Integer;
7   begin
8     for i := Length(S) downto 1 do
9       if S[i] in characters then
10        delete(S, i, 1);
11  end;
12  
13  
14  //In your case you would call it as:
15  
16  
17  RemoveCharacters(aString, [' ']);
18  
19  
20  //There are certainly faster ways to implement this but unless you call the 
21  procedure some ten-thousand times in a loop I would not worry about that.

23  function RemoveCharsFromString(const TheString: string; const CharsToRemove: array
24    of Char): string;
25  var
26    i:
27    Integer;
28  begin
29    Result := TheString;
30    for i := Low(CharsToRemove) to High(CharsToRemove) do
31    begin
32      Result := StringReplace(Result, CharsToRemove[i], '', [rfReplaceAll]);
33    end;
34  end;

35  type
36    TSetOfChar = set of char;
37  
38  function RemoveCharsFromString(const TheString: string;
39    const CharsToRemove: TSetOfChar): string;
40  var
41    i, j: Integer;
42  begin
43    SetLength(Result, length(TheString));
44    j := 0;
45    for i := 1 to length(TheString) do
46    begin
47      if not (TheString[i] in CharsToRemove) then
48      begin
49        inc(j);
50        Result[j] := TheString[i];
51      end;
52    end;
53    SetLength(Result, j);
54  end;
