I am currently working on Flex automation

I have a challenge in setting date in the date field below is the object hierarchy through QTP.

Browser("").FlexApplication("").FlexBox("").FlexPa nel("").FlexForm("").FlexDateField

I have tried SetDate,Set,selectdate,select none of the methods have helped me solve the issue.

Manually when I select the date I am getting the date in the format Mon-dd-yyyy(Sep-18-2014)

Thanks for all your support in advance.
