[pmtzg]

gracias por tu ayuda pero
me manda un mensaje de error


me dice :

program or unit 'bde' recursively uses itself

y no corre el programa.

este es el cogigo completo :

Código Delphi [-]
function TForm1.GetConfigParameter(Param: string; Count: pword): string;
var
  hCur: hDBICur;
  rslt: DBIResult;
  Config: CFGDesc;
  Path, Option: string;
  Temp: array[0..255] of char;
begin
  Result := ''; hCur := nil;
  if Count <> nil then
    Count^ := 0;
  try
    if Pos(';', Param) = 0 then
      raise EDatabaseError.Create('Invalid parameter passed to function.  There must ' +
         'be a semi-colon delimited sting passed');
    Path := Copy(Param, 0, Pos(';', Param) - 1);
    Option := Copy(Param, Pos(';', Param) + 1, Length(Param) - Pos(';', Param));
    Check(DbiOpenCfgInfoList(nil, dbiREADONLY, cfgPERSISTENT, StrPCopy(Temp, Path), hCur));
    Check(DbiSetToBegin(hCur));
    repeat
      rslt := DbiGetNextRecord(hCur, dbiNOLOCK, @Config, nil);
      if rslt = DBIERR_NONE then
      begin
        if StrPas(Config.szNodeName) = Option then
          Result := Config.szValue;
        if Count <> nil then
          Inc(Count^);
      end
      else
        if rslt <> DBIERR_EOF then
          Check(rslt);
    until rslt <> DBIERR_NONE;
  finally
    if hCur <> nil then
      Check(DbiCloseCursor(hCur));
  end;
end;
