**UniquePosition, Protected**

{{blk2blue.jpg|blk2blue.jpg}}

The **UniquePosition** method checks the FileDropComboClass's queue for a duplicate record by checking for duplicate key values. A return value of zero (0 or False) means there was a matching value already in the queue. Any other return value indicates no match was found.

**Implementation:**

The UniquePosition method is called by the FileDropComboClass.AddRecord method which checks for duplicate values before adding the record to the filedropcombo's queue.

**Return Data Type:**     LONG
