Jess,

I was only using a jpg file to prove to you that VFP can indeed handle binary data inside a memo.

I think you may have an issue passing the memo field directly back to the OCX:

cBinary = Thisform.OleOCX.GetFingerPrint()
Replace mydbffile.memofield With cBinary

lcCheckFingerPrint = mydbffile.memofield && convert from memo back to string
cBinaryCheck = Thisform.OleOCX.CheckFingerPrint(lcCheckFingerPrint) && send string

>This is exactly my problem. Actually the OCX emits binary data. It is not a file.
