[Redemption] Retrieve a contact by his EntryID

[Samildanach]

Hi, i think all is in the title

I use redemption to retrieve/export datas of Outlook. And I need to find a contact by his EntryId. So i use the method Find, in which a WHERE clause can be used but as the entryID parameter is an hexadecimal, i am not sure i do the right request. I tried a lot a variation like :
Find(EntryID = 'myValue')
or
Find(EntryID = myValue)
or
Find(EntryID LIKE 'myValue')

no one works

i don't know if it's important but i use C++ (i know i'm not in the right section ;-) )

if someone can help me

Thanks
