Identifier

A HistoryField object, representing one field of a record.

Return value

A reference to an array of strings is returned.

Example

Perl

# This example assumes that there is at least 1 history 

# field associated with the record. Otherwise, GetHistoryFields

# won't return anything interesting and an error would be generated

$session = $entity->GetSession();

# Get the collection of history fields

$historyfields = $entity->GetHistoryFields();



# Get the first history field

$historyfield1 = $historyfields->Item(0)



# Get the list of unique keys for identifying each history.

$keys = $historyfield1->GetDisplayNameHeader();



# Iterate through the list of keys and print the key value

$x = 0;

foreach $key (@$keys)

 {

 $session->OutputDebugString("Displaying key number".$x." - 

      ".$key);

 $x++;

 }
