LogInfo

LogInfo can be one of the most useful and versatile tools at your disposal.

LogInfo creates an entry in the action Log of type User Info.

Declaration: procedure LogInfo (aMesg : string);

A simple example follows.

procedure OnMapEvent(var Value:Variant);
begin
  if MyData.EOF then
    LogInfo ('You are at the end of records in MyData recordset');
end;

LogInfo can be used for just about anything - as is illustrated in the Log snippet below, that was generated from the code block that follows.

  vDigits := ['0','1','2','3','4','5','6','7','8','9'];
  vCurrSym := ['$',',','.'];
  vStr1 := '$123.00';                        // digits and currency symbols only
  vStr2 := 'NZD123.00';                      // includes alpha characters
 
  LogInfo('');
  // test first string ... it should be OK
  If StringContainsOnly(vStr1, vDigits + vCurrSym) then
    LogInfo('String "' + vStr1 + '" contains only 0-9,$,.')
  else
    LogInfo('String "' + vStr1 + '" contains other than 0-9,$,.');
 
  // test second string ... it should fail
  If StringContainsOnly(vStr2, vDigits + vCurrSym) then
    LogInfo('String "' + vStr2 + '" contains only 0-9,$,.')
  else
    LogInfo('String "' + vStr2 + '" contains other than 0-9,$,.');
 
  LogInfo('');

To cause a blank line in the log, use LogInfo('') as above.
