There has to be a simple way to do this that I am missing?

Of course one could strip out the '$' and ',' in code, it just seems those brilliant bunch of folks at Borland would have provided for this eventuality.

Thanx in andvance,

Greg

From the Delphi help file:

The DecimalSeparator global variable defines the character that is used as a decimal point. Thousand separators and currency symbols are not allowed in the string. If the string doesn't contain a valid value, StrToCurr raises an EConvertError exception.

Try this out for size instead:


Function StrToCurrEX(str:string;Delimiter:char;denominator:char):string;
var tempstr:string;
    Dollarsign,Comma:integer;
begin
   Tempstr:=str;
   Dollarsign:=pos(denominator,Tempstr);
   if dollarsign<>0 then Delete(Tempstr,dollarsign,1);
   Comma:=Pos(Delimiter,tempstr);
   if Comma<>0 then delete (Tempstr,comma,1);
   Result:=strToCurr(Tempstr);
end;



And just use FormatStr to get it all back.


Good luck!!

Copy that Doc!

There must be away to pass/convert a string like '$1,569.34' to
Fields[i].SomeThing := String; where fields[i] is a currency or float type.

Without having to preprocess the string to meet ‘1569.34’ first.

It just seems goofy that StrToCurr('$1,569.34') can’t handle this, it is after all pretty obviously a currency string!

Well, I suppose you could derive a new descendant class from TField and add a .AsMoney method to it... of course you'd have to put that into a string field (or blob, etc)... chances are that the table isn't going to like it otherwise.


Good luck!!

Thanx Doc,

Your code my style, works great, still can't believe this is not built into the language.

// Remove $ and , from currency strings --------- 1:00 PM 4/19/2002gr
function myStrToCurrEX( s: String): String;
var
   d, c: Integer;

begin
  // String Contains '$' Sign?
  d := pos( '$', s);
  if (d <> 0) then
    Delete( s, d, 1);

  // String Contains ',' Sign?
  c := Pos( ',', s);
  if (c <> 0) then
    Delete( s, c, 1);

    RESULT := s;

end;
