Hi,
I have a problem to check value of field in OnValidate event whether the 
field's type is TWidwStringField.
I am using MS access 2000 , C++ Builder 2006 under Windows XP. I get error:
Exception class EAccessViolation with message 'Access violation at address 
7714CA1E in module 'oleaut32.dll'. Read of address 00343000
 Previously I was using C++ Builder 5, it worked.
The code is as follows:

void __fastcall TForm2::ADOTable1textdate1Validate(TField *Sender)
{
     if(Sender->AsString.IsEmpty())
        // TODO
}

Any ideas???
Regards,
Oleg
