I'm using an Interbase table, and have a field called field called "DOS" and
it's a date field.  How do i check if it's an empty date field.  This code
doesn't seem to work

if (DMOD->tableName->FieldByName("DOS")->Value != NULL) {
    // it should be an empty date field
} else {
    // it's not empty
}

Thanks for any help in advance
Jason

Sorry, had a little typo in the comments

if (DMOD->tableName->FieldByName("DOS")->Value != NULL) {
    // it should not be empty
 } else {
     // it should be empty
}
