Save fingerprint data in sql VB6

I have to "update" a fingerprint system that works with vb6 but the digital personal SDK is no longer handled in platinum but in one touch it is in platinum to make the connection and save the data was:

    Dim blob() As Byte
    Dim bvariant As Variant
    If regtemplate Is Nothing Then
      Exit Sub
    End If
    regtemplate.Export bvariant
    blob = bvariant

But when doing the migration to the new SDK I was left in zeros in this part since regtemplate was replaced by 3 lib.

SDK Platinum

Dim WithEvents op As FPRegisterTemplate         
Dim regtemplate As FPTemplate  

SDK One Touch

Dim WithEvents Capture As DPFPCapture 
Dim CreateFtrs As DPFPFeatureExtraction
Dim CreateTempl As DPFPEnrollment 
Dim ConvertSample As DPFPSampleConversion
